Middle-Tier Administration
SAS Web Server and SAS Web
Application Server
The SAS 9.4 middle-tier software includes SAS Web Server for use as an HTTP server and SAS Web Application Server. SAS Web Application Server is a lightweight server that provides enterprise-class features for running SAS web applications. Both products can be installed and configured automatically with the SAS Deployment Wizard.
Enhancements to Support SAS Web
Application Server Clustering
The SAS Deployment Wizard has been enhanced to simplify clustering SAS Web
Application Server. In previous releases, the following steps required manual configuration, but are performed automatically in this release: n install a Java environment and web application server software n create repository configuration files for each instance of SAS Content Server n configure a load-balancing HTTP server
With the enhancements, you can easily configure vertical cluster members (additional server instances on the same machine) and horizontal cluster members (install and configure servers on additional machines).
Combining vertical and horizontal clustering is also supported and can be configured easily.
Enhancements to SAS Logon Manager
xi
SAS Environment Manager
SAS Environment Manager provides a number of systems and application management features for managing the SAS servers in your deployment. An agent is installed on each machine in the deployment. The agent collects metrics from the server processes and operating system running on the machine and sends them to the SAS Environment
Manager server.
Both the agents and the server can be installed and configured automatically with the
SAS Deployment Wizard.
SAS Web Infrastructure Platform Data
Server
SAS Web Infrastructure Platform Data Server replaces the SAS Framework Data
Server that was used in SAS 9.3. The data server provides a transactional store for
SAS middle-tier software.
The server can be installed and configured automatically with the SAS Deployment
Wizard. The server is based on PostgreSQL 9.1.9. SAS configures a single server instance and SAS Web Application Server instances are configured with JDBC data sources that access the server. SAS Environment Manager also stores transactional information in the server.
Enhancements to SAS Logon Manager
In previous releases, the SAS Logon Manager enabled administrators to deny concurrent logons. In this release, this feature is enhanced to offer the ability to log off

the existing session. This setting enables users can access to the applications that they need and administrators are assured that only one session is active at a time.
For SAS 9.4, SAS Logon Manager uses the Central Authentication Service (CAS) that is available from Jasig. This change enables single sign-on so that users to access multiple SAS web applications seemlessly.
Enhancements for SAS Content Server
SAS Content Server is a web application that provides WebDAV features for your SAS deployment. The SAS 9.4 release includes an update for SAS Content Server to provide JCR 2.0 features.
By default, the SAS Content Server is also enhanced to use the SAS Web Infrastructure
Platform Data Server for storage. In previous releases, this was an option during the installation process. Using the database for storage simplifies using SAS Content
Server in a web application server cluster because there is no longer any need for repository reconfiguration.
Support for Web Application Archive
Files
In previous SAS releases, the SAS web applications were managed and deployed as enterprise web application archive (EAR) files. For the SAS 9.4 release, the web applications are managed as EAR files, but they are deployed as web application archive (WAR) files.

Understanding the Middle-Tier
Environment
The middle tier of the SAS Intelligence Platform enables users to access intelligence data and functionality with a web browser. This tier provides web-based interfaces for report creation and information distribution, while passing analysis and processing requests to the SAS servers.
The middle tier of the SAS Intelligence Platform provides an environment for running applications such as SAS Web Report Studio and SAS Information Delivery Portal.
These applications run in a web application server and have a graphical user interface that users navigate with a web browser. These applications rely on servers on the SAS server tier to perform SAS processing, including data query and analysis.

n the Cache Locator, which is used by SAS web applications to locate and connect to a distributed cache. The SAS web applications use the cache to maintain awareness of user sessions and to share application data.
n
SAS Environment Manager, which is used to monitor and manage the server tier and middle tier of the SAS deployment.
The SAS Intelligence Platform architecture provides the flexibility to distribute these components according to your organization's requirements. For small implementations, the middle-tier software, SAS Metadata Server, and other SAS servers, such as the
SAS Workspace Server and SAS Stored Process Server, can all run on the same machine. In contrast, a large enterprise might have multiple servers and a metadata repository that are distributed across multiple platforms. The middle tier in such an enterprise might distribute the web applications to many web application server instances on multiple machines.

Cache Locator
SAS Web Application Server uses the distributed data cache that is available with
VMware vFabric GemFire. SAS uses the cache as a peer-to-peer cache. In order for the instances of SAS Web Application Server to join as members of the cache, the Cache
Locator is used. The locator provides the mechanism for peer discovery. The locator is used by instances of SAS Web Application Server and the SAS Web Infrastructure
Platform Scheduling Services.
SAS Environment Manager
The SAS middle-tier environment includes SAS Environment Manager. This software includes an agent process that is installed on each server-tier and middle-tier machine in the deployment. Each agent gathers performance metrics and transfers the data to a server process that runs on a middle-tier machine. The server process includes a web application server that provides a web-based administrative interface.. Administrators use a web browser to monitor and manage numerous components in the SAS environment.
SAS Web Infrastructure Platform
The SAS Web Infrastructure Platform is a collection of services and applications that provide common infrastructure and integration features for the SAS web applications.
Services and Applications in the SAS Web
Infrastructure Platform
Services and applications in the Web Infrastructure Platform provide the following benefits: n consistent installation, configuration, and administration tasks for web applications n consistent user interactions with web applications, such as logon n integration among web applications as a result of sharing common resources

A user enters information in an HTML form using a web browser and then submits it. The information is sent to a web server, which invokes the first component, the SAS
Stored Process Web Application.
The Stored Process Web Application accepts data from the web server, and contacts the SAS Metadata Server for retrieval of stored process information.
3
4
5
The stored process data is then sent by the Stored
Process Web Application to a stored process server via the object spawner.
The stored process server invokes a SAS program that processes the information.
The results of the SAS program are sent back through the web application and web server to the web browser.
Enables administrators to create and edit messages that are sent as notifications to end users of SAS applications.

In the middle tier, the SAS Web Infrastructure Platform plays a critical role with a collection of middle-tier services and applications that provide basic integration services.
In the web application server, two sets of services are available to all SAS web applications: n
SAS Foundation Services
SAS Web Infrastructure Platform
13 n
SAS Web Infrastructure Platform Services
SAS Foundation Services
The SAS Foundation Services is a set of core infrastructure services that enables Java programmers to write distributed applications that are integrated with the SAS platform.
This suite of Java application programming interfaces provides core middleware infrastructure services. These services include the following: n client connections to SAS Application Servers n dynamic service discovery n user authentication n profile management n session management n activity logging n metadata and content repository access n connection management n
WebDAV service
Extension services for information publishing, event management, and SAS Stored
Process execution are also provided. All of the SAS web applications that are described in this document use the SAS Java Platform Services. If you have correctly installed and configured the web applications, the platform services are defined in your SAS metadata repository.
You can verify this metadata in the SAS Management Console. Depending on the web applications that were installed, the SAS Portal Local Services (used by the SAS
Information Delivery Portal) are displayed in the SAS Management Console.
In addition, other applications and portlets might have deployment of their own local services.
14
Chapter 1 / Working in the Middle-Tier Environment
SAS Web Infrastructure Platform Services
The SAS Web Infrastructure Platform Services provide common infrastructure and integration features that can be shared by any SAS application. Here is a description of the features: n
Audit provides a single, common auditing capability.
n
Authentication is a common method for authenticating middle-tier applications. A corresponding web service provides connectivity based on WS security standards for web service clients.
n
Configuration is a standard way to define, store, and retrieve configuration information for SAS applications.
n
Directives provide application integration so that SAS applications can share intelligence and data. Applications can link to one another without requiring specific information about a particular deployment location.
n
Mail is a single, common mechanism for Simple Mail Transfer Protocol (SMTP)based mail.
n
Status and monitoring is a collective set of services providing information about the configured or functioning system.
n
Comment service enables users to add comments, with or without an attachment.
This feature enables the capture of human intelligence and supports collaborative decision making related to business data.
n

Portal.
n
Themes provide access to theme definitions for presentation assets used in web applications.
n
SAS Workflow Services enable applications to interact with business processes that run in the SAS Workflow Engine.
SAS Content Server
15 n
Registry provides access to services for desktop clients; a client needs to know only a single endpoint to determine other required locations.
SAS Workflow
SAS Workflow provides services that work together to model, automate, integrate, and streamline business processes. It provides a platform for more efficient and productive business solutions. SAS Workflow is used by SAS solutions that benefit from business process management.
SAS Workflow Studio is a desktop client application that is used to design and deploy workflows. The SAS middle tier hosts the workflow engine and the workflow services.
SAS Content Server
The SAS Content Server is part of the SAS Web Infrastructure Platform. This server stores digital content (such as documents, reports, and images) that is created and used by SAS web applications. For example, the SAS Content Server stores report definitions that are created by users of SAS Web Report Studio, as well as images and other elements that are used in reports. A process called content mapping ensures that report content is stored using the same folder names, folder hierarchy, and permissions that the SAS Metadata Server uses to store corresponding report metadata.
In addition, the SAS Content Server stores documents and other files that are to be displayed in the SAS Information Delivery Portal or in SAS solutions.
To interact with the SAS Content Server, client applications use Web Distributed
Authoring and Versioning (WebDAV) based protocols for access, versioning, collaboration, security, and searching. Administrative users can use the browser-based
SAS Web Administration Console to create, delete, and manage permissions for folders on the SAS Content Server. Administrative users can also search the SAS Content
Server by using industry-standard query syntax, including XML Path Language (XPath) and DAV Searching and Locating (DASL).
16
Chapter 1 / Working in the Middle-Tier Environment
SAS Web Applications
The SAS web applications described in this section have user interfaces that are used by people other than administrators. These applications require a web browser on each client machine and run in an instance of SAS Web Application Server that is installed on a middle-tier machine. These applications communicate with the user by sending data to and receiving data from the user's web browser. For example, these applications display a user interface by sending HTML that includes HTML forms, Java Applets, or
Adobe Flash content. The user can interact and submit input to the application by sending an HTTP response, usually by clicking a link or submitting an HTML form.
SAS Web Report Studio
SAS Web Report Studio is a web application that anyone can use to view, interact with, create, and distribute public and private reports. Reports can be scheduled to run unattended on a recurring basis and then distributed using e-mail. SAS Web Report
Studio requires the SAS BI Report Services (which includes the report output generation tool) and the SAS BI Report Services Configuration (which creates libraries used by the SAS Web Report Studio).
SAS Information Delivery Portal
The SAS Information Delivery Portal is a web application that enables you to aggregate data from a variety of sources and present the data in a web browser. The web browser content might include the output of SAS Stored Processes, links to web addresses, documents, syndicated content from information providers, SAS Information Maps, SAS reports, and web applications. The portal also provides a secure environment for sharing information with users.
Using the portal, you can distribute different types of content and applications as appropriate to internal users, external customers, vendors, and partners. You can use the portal along with the Publishing Framework to perform the following tasks: n
Publish content to SAS publication channels or WebDAV repositories
SAS Web Applications
17 n
Subscribe to publication channels n
View packages published to channels
The portal's personalization features enable users to organize information about their desktops in a way that makes sense to them.
For more information, see the SAS Information Delivery Portal Help, which is available from within the product.
SAS BI Dashboard
SAS BI Dashboard enables users to create, maintain, and view dashboards to monitor key performance indicators that convey how well an organization is performing. SAS BI
Dashboard includes an easy-to-use, drag and drop interface for creating dashboards that include graphics, text, colors, and hyperlinks. The application leverages Flash in the
Rich Internet Application (RIA) architecture.

Chapter 1 / Working in the Middle-Tier Environment
SAS BI Portlets
The SAS BI Portlets are based on JSR 168 and are available with SAS Enterprise
Business Intelligence Server. These portlets are seamlessly integrated into the SAS
Information Delivery Portal. SAS BI Portlets enable users to access, view, or work with content items that reside in either the SAS Metadata Server or the SAS Content Server.
SAS Help Viewer for the Web
Your installation can include the SAS Help Viewer for the Web. This application enables users to view and navigate SAS online Help in the various SAS web applications. This application combines the Help viewer with the Help content for various SAS web applications and creates a WAR file that is deployed on the web application server.
Users access the Help contents for each application through the Help menu that is provided with each SAS web application.
The application also provides an administrative interface that is used to view the status of the documentation products. Administrators can use this interface to determine whether the documentation products were installed correctly, or whether there was a configuration problem. The administration interface is available from http://
hostname.example.com/SASWebDoc.

Configuration Shared between the
Middle Tier and the Server Tier
The web applications and services that form the SAS middle tier require specific connections to servers that are associated with the server tier. You might want to modify the connections and settings in the following ways: n
Change the connection to an SMTP mail server.
22
Chapter 2 / Interacting with the Server Tier
n
Understand the use of the SAS Web Infrastructure Platform Data Server.
n
Modify the JDBC data source that provides a connection to a relational database.
n
Modify the Job Execution Services settings.
SMTP Mail Server
The SAS Web Infrastructure Platform includes a SAS Mail Service that is used by SAS web applications and services to send e-mail messages such as alert notifications and administrative status updates. The SAS Mail Service relies on a Java Mail Session that is defined in SAS Web Application Server. The Java Mail Session provides the single point of configuration to an external SMTP mail server that your site designates to use for application e-mail. Because the SAS Mail Service relies on this single configuration location, if the SMTP mail server changes, you can modify the appropriate settings in a single place.
The Java Mail Session depends on configuration information that defines the mail transport capabilities. The SAS Mail Service requires that the following minimum set of mail properties be specified: mail.transport.protocol
This property must be set to smtp.
mail.smtp.host
This property must be set to the host name of the SMTP mail server.
mail.smtp.port
This property must be set to the corresponding port (typically 25 for SMTP servers).
mail.debug
This property is set to false. You can set the value to true for assistance with debugging mail transactions.
In a standard installation of SAS middle-tier components, the configuration of the Java
Mail Session is typically automated using prompted values that are provided by the installer. To modify the settings for the Java Mail Session (for example, if the host name
SAS Web Infrastructure Platform Data Server
23 of the SMTP mail server changes), edit the SAS-config-dir\Levn\Web
\WebAppServer\SASServer1_1\conf\server.xml file. If you have more than one server instance, edit the server.xml file for each server. Change the following line:
<Resource auth="Container"
mail.smtp.host="smtp.example.com"
mail.smtp.port="25"
name="sas/mail/Session"
type="javax.mail.Session"/>
If the mail server information, such as host name or port number, is changed, then it must be changed in SAS metadata as well. To set the new values, follow these steps:
1 Log on to SAS Management Console and select Application Management
Configuration Manager.
2
Right-click SAS Application Infrastructure and select Properties.
3
Click Advanced, and then set the new values for Email.Host or Email.Port.
SAS Web Infrastructure Platform Data
Server
About the Server
SAS Web Infrastructure Platform Data Server is included in your deployment for use as transactional storage by SAS middle-tier software and some SAS solutions software.
The server is based on PostgreSQL 9.1.9. The server is configured specifically to support SAS software. Some of the settings are provided in the next section.
The server is automatically configured by the SAS Deployment Wizard during installation and configuration. By default, the SAS installer account is used to start the server.
The databases that are managed by the server are backed up and restored with the
Backup and Recovery Deployment Tool. For information about the tool, see SAS
Intelligence Platform: System Administration Guide.
24
Chapter 2 / Interacting with the Server Tier
Installation Directory
The SAS Deployment Wizard installs and configures a server instance in the SAS-
config-dir\Lev1\WebInfrastructurePlatformDataServer directory. This path includes the following script and directories: webinfdsrvc.bat
This script is used to start, stop, and determine the running status for the server. It specifies the network port number and the path to the data directory. For UNIX deployments, the script is named webinfdsrvc.sh and is configured to start the server as the SAS installer account.
data
This directory contains server configuration files and the data files for the databases that are managed by the server. SAS configures the server to store data in the
UTF-8 character encoding. Do not modify the files in this directory without direction from SAS technical support.
Logs
SAS configures the server to generate log files in this directory. Log files are rotated automatically after they reach 10 MB.
The _webinfdsvrc_console.log file is generated during start-up. Look at this log first if you have trouble starting the server.
Databases
In a SAS 9.4 Enterprise Business Intelligence deployment, the server is configured to manage the following databases:
Administration
This database contains configuration information for the modules that SAS develops to extend the features of SAS Environment Manager.
SAS Web Infrastructure Platform Data Server
25
EVManager
This database is used by SAS Environment Manager. The database contains configuration and metric information for the machines and servers that SAS
Environment Manager manages in your deployment.
SharedServices
This database is used by the SAS web applications and middle-tier software. For example, comments that are added through various web applications are stored in this database. Digital content that is stored with SAS Content Server is also stored in this database.
Note:
You can choose to use a third-party vendor database server for this database when you install and configure software with the SAS Deployment Wizard. This database is identified as the SAS Web Infrastructure Platform Database on the pages in the wizard.
If your deployment includes SAS solutions software that supports SAS Web
Infrastructure Platform Data Server, then more databases might be configured on the server.
Network Access
The server is configured to accept connections on all network interfaces and requires password authentication. By default, SAS configures the server to use network port number 9432. This network port number avoids conflicts with the default port (5432) that other PostgreSQL servers might use.
SAS Web Application Server instances are configured with JDBC Data Sources that reference the SharedServices database and the Administration database. SAS
Environment Manager is configured for access to the EVManager and the
Administration database.
26
Chapter 2 / Interacting with the Server Tier
JDBC Data Sources
About the Data Sources Used by the Middle
Tier
The SAS Web Infrastructure Platform and some solutions provide a set of features that rely on a relational database to store service data. These relational tables differ from the data that is analyzed, modeled, or otherwise processed by SAS applications, which typically is derived from a site's enterprise or legacy sources. Instead, the relational tables in the SAS Web Infrastructure Platform database are intrinsic to or used primarily for the operations of a particular application, product, or service.
SAS web applications and services access data from the SAS Web Infrastructure
Platform database through JDBC. SAS Web Infrastructure Platform provides support for the following third-party vendor databases: n
Oracle Database n
IBM DB2 n
Microsoft SQL Server n
MySQL n
PostgreSQL n
Teradata Database
Your site can choose to use the database that you are familiar with. However, some
SAS solutions have requirements for specific databases. Consider these requirements when you select a database to use as the data source for the SAS Web Infrastructure
Platform. As a default option, the SAS Web Infrastructure Platform Data Server can be configured as the data source for SAS Web Infrastructure Platform.
JDBC Data Sources
27
Connection Information for the JDBC Data
Source
The database used by the SAS Web Infrastructure Platform must be configured in SAS
Web Application Server as a JDBC data source. The JDBC data source is configured with the JDBC driver and connection information for the selected database. These settings are provided to the SAS Deployment Wizard during installation and configuration. You need to know the JDBC connection parameters if you make changes later, such as changing the connection to access a database on another machine.
JDBC connection settings typically require a user ID and password for access to the data source.
The default database server for SAS Web Infrastructure Platform is the SAS Web
Infrastructure Platform Data Server. The JDBC connection parameters for the server are provided in the following table:
Table 2.1 JDBC Connection Parameters for SAS Web Infrastructure Platform Data Server

In the URL, substitute the server name and port number of the
SAS Web Infrastructure Platform Data Server at your site. The default port is 9432.
org.postgresql.Driver
These settings are configured during initial deployment. However, you need to know the connection information if you make changes later, such as moving the server to another host system.
Note:
You must specify the user name and password values as required to access the data source.
28

The service provides a common, standardized way for applications to create, submit, store, retrieve, and queue jobs for SAS servers. The service can be configured with the
Configuration Manager plug-in to SAS Management Console. The settings define the
Job Execution Service
29 job thread pool and the execution thread pools for all logical servers that the service uses for delegating work.

Jobs are kept in memory only if persistence is disabled. If persistence is disabled and the
SAS Web Infrastructure Platform Services application or the web application server is stopped, then no records are written to the
SAS Web Infrastructure Platform database about any jobs that were submitted. When persistence is enabled, the job execution services can restart any jobs that were submitted, queued, or running. For jobs that are complete, clients can fetch the results after a restart, when persistence is enabled.
Note:
Persistence must be enabled when
SAS Web Application Server is clustered.
If enabled, then the distributed in-process scheduler is used for running scheduled jobs.
Disable this setting if Platform Suite for SAS is available and the preferred scheduling method.
Use the controls to select the server context to configure.
If enabled, then the servers in the associated server context perform interactive workspace tasks and interactive stored process tasks only. If disabled, then the servers can perform batch and interactive job execution.

Description
Maximum number of task threads to create if the demand requires additional resources.
You can associate resources with servers and then a job can specify that it requires a resource. For example, you can associate a printer name with SASApp. When a client submits a job, and specifies that it requires the printer resource, the job execution service makes sure that the job runs on that server even when other servers are available.
The default settings are designed to provide good performance in a variety of operating environments. Before modifying the settings, consider enabling the auditing features of the job execution services to review the performance with the default settings. For
information about enabling auditing, see “Configuring Auditing for SAS Web
.
To modify any of these settings, follow these steps:
1
Log on to SAS Management Console as an administrator.
2
On the Plug-ins tab, navigate to Application Management
Configuration
Manager SAS Application Infrastructure Web Infra Platform Services 9.4.
3 Right-click JobExecutionService and select Properties.
4 Click the Settings tab.
5 Modify the settings and then click OK.
Settings are not applied and made active automatically. They are activated when restart the SAS Web Infrastructure Platform Services or SAS Web Application Server.
Alternatively, you can set the state of some properties at run time through the JMX bean
(MBean) for the service with a JMX console.

About SAS Web Server
SAS Web Server is an HTTP server. The server is based on VMware vFabric Web
Server. SAS configures the server with the following features: n automatically configured as a load-balancing HTTP server when SAS Web
Application Server is clustered.
38
Chapter 3 / Administering SAS Web Server
n automatically updated to route web sessions (round robin) to SAS Web Application
Server instances when clustered.
n can be configured for HTTPS automatically. You must supply a signed certificate and a private key. You can follow manual steps to change a configuration that used
HTTP to HTTPS.
n automatically configured to cache static web content like JavaScript files, cascading style sheets, and graphics files.
The followinge advanced configurations are possible, but require manual configuration that is not automatically updated: n adding instances of SAS Web Server to form a cluster n interacting with customer-supplied load-balancing hardware or software
Installing SAS Web Server
Automatic Configuration
SAS Web Server is installed with the SAS Deployment Wizard. The wizard can also automatically configure the server. By default, the server is installed on the same machine as SAS Web Application Server. However, because the topology is defined in a plan file that the wizard uses, the server can be deployed to a different machine if the topology is defined that way in the plan file.
To use this feature, select the Configure SAS Web Server automatically check box on the SAS Web Server: Automated or Manual Configuration Option page of the SAS
Deployment Wizard.
Manual Configuration
If you prefer to configure SAS Web Server manually, make sure the Configure SAS
Web Server automatically check box is not selected when you use the SAS
Deployment Wizard. Once the wizard completes, the Instructions.html file provides step-
Installing SAS Web Server
39 by-step instructions that describe how to configure the server manually. The instructions are customized for your deployment, including the correct host names and file system paths.
If you choose to configure the server manually, you must also configure SAS Web
Application Server manually.
Using HTTPS
If you plan to use HTTPS, then it is best to enable the feature during the installation and configuration time frame with the SAS Deployment Wizard. The SAS Deployment
Wizard prompts for a CA-signed certificate and private key. Both must be in PEM encoded format.
If you have a CA-signed certificate, the SAS Deployment Wizard prompts for the path to the certificate and the path to the RSA private key that is not protected with a pass phrase. An RSA private key file that is not protected with a pass phrase begins as follows:
Example Code 3.1 RSA Private Key without a Pass phrase
-----BEGIN RSA PRIVATE KEY-----
MIICXgIBAAKBgQC4vPQMyiVKvjIERVNfa34iVxeauzcUa8zc2xBHRlJ43uAvvWuL
63yeGl8QQoT55yqhAWhs62i24lE34t2ituhCm0QYbU1KiyB9PNyfOk3/2E7Y7o1T
Do not use an encrypted private key. An encrypted RSA private key file begins as follows:
Example Code 3.2 Encrypted RSA Private Key
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,FB353F5E4F1719EB

Io5V/YZUa+uGG82ULsAUy3zWTHP+OjxpTV/3gjLwbmD3+JM5Dd0jFLGenfPF5hld
The SAS Deployment Wizard also prompts for the certificate. A certificate file from a certificate authority typically begins as follows:
Example Code 3.3 Certificate Authority-Signed Certificate
Certificate:
Data:

Understanding the SAS Web Server
Configuration
The default location for SAS Web Server is SAS-config-dir\Levn\WebServer. Key files and directories are as follows:
bin
This directory includes a command for starting and stopping the server. For more
information, see “Using the httpdctl Command”
.
conf
SAS software manages the configuration files in this directory. If you modify a file, your customizations are overwritten the next time SAS software configures the server.
Do not modify configuration files manually. Many settings, such as network port number, are managed in SAS metadata as well. Use the SAS Deployment Manager and SAS Deployment Wizard for configuring SAS Web Server.
ssl
If you enabled HTTPS during installation and configuration with the SAS Deployment
Wizard, then this directory is used to store the certificate and private key for the server. If you supplied a CA-signed certificate and private key to the wizard, both files are copied to this directory. The files are also renamed to include the host name, as follows:
hostname.crt
hostname.key
Understanding SAS Web Server Management
41
TIP If you need to replace a certificate—for example, to avoid having a certificate expire—then replace the file in this directory.
Understanding SAS Web Server
Management
Using the httpdctl Command
The server is configured with a httpdctl.ps1 command in the bin directory. On
UNIX and z/OS, the command is httpdctl.
UNIX Specifics:
If you configured SAS Web Server to use network port numbers below
1024, then you must run the httpdctl command with super user privileges, such as
sudo.
sudo ./httpdctl restart
Windows Specifics:
The httpdctl.ps1 is a Windows PowerShell script. You might need to set the execution policy with powershell set-executionpolicy
remotesigned.
powershell .\httpdctl.ps1 restart
Using the appsrvconfig Command
A configuration scripting tool for SAS Web Server is located in the SAS-config-dir
\Levn\Web\Scripts\WebServer directory. The appsrvconfig.cmd command can be used for starting, stopping, and restarting SAS Web Server.
appsrvconfig.cmd start appsrvconfig.cmd stop appsrvconfig.cmd restart
The actual task is identified in a command task file that is located in the SAS-config-
dir\Levn\Web\Scripts\WebServer\props. The file is generated and then executed. The file does not exist until the appsrvconfig.cmd command is used.
42
Chapter 3 / Administering SAS Web Server
Information about using the appsrvconfig.cmd command for configuration tasks is
provided in SAS Configuration Scripting Tools on page 301
.
Using Windows Services
For deployments that use the Windows operating environment, the default action for the
SAS Deployment Wizard is to register each server instance as a service. The naming convention is similar to the following example:
SAS [Config-Lev1] httpd - WebServer
Using SAS Environment Manager
SAS Environment Manager provides an interface that you can access with a web browser. You can start and stop SAS Web Server with the web interface.
Monitoring SAS Web Server
Viewing Performance with SAS Environment
Manager
The primary user interface for monitoring the server is SAS Environment Manager.
Numerous metrics are collected from the server.
In SAS Environment Manager, SAS Web Server is represented as vFabric Web
Server 5.2 Virtual Host.
For administrators that are familiar with monitoring Apache HTTP Server, the metrics that are collected for vFabric Web Server 5.2 Virtual Host are related to mod_bmx.

Viewing Load-Balancing Statistics
SAS Web Server is configured to load-balance requests, even if only one SAS Web
Application Server instance is configured. You can access the information by opening a web browser from the machine that is hosting SAS Web Server and accessing the following URL: http://localhost/balancer-manager
The web page provides information about each load balancer. Some of the information is identified in the following list: n routes (each instance of SAS Web Application Server is identified as a route) n route status n the amount of network traffic to and from each route

Chapter 4 / Administering SAS Web Application Server
About SAS Web Application Server
SAS Web Application Server is a lightweight server that provides enterprise-class features for running SAS web applications. The server is based on VMware vFabric tc
Server. By packaging the server and software that can automate server configuration tasks, SAS simplifies the demands for managing a web application server.
Though the server is based on a commercially available third-party software product, the server is deployed and configured specifically to provide an environment for the
SAS web application and the middle-tier environment. The configuration tools that are packaged with the software ease the administration of the server in a SAS environment because the tools are designed to interact with the SAS Metadata Server and other
SAS software products to maintain reliability and reduce administration in the SAS deployment.
The following list identifies some enhancements that are implemented in SAS Web
Application Server: n automatically connects to Cache Locator on server start-up for distributed communication.
n accesses the JMS resources provided by JMS Broker.
n automatic directory scanning for changes to files is disabled. This change conserves computing resources.
n
JAR file scanning is optimized to reduce start-up times.
Installing SAS Web Application Server
Automatic Configuration
By default, SAS Web Application Server is installed by the SAS Deployment Wizard when you install SAS software for your deployment. The SAS Deployment Wizard can
Installing SAS Web Application Server
47 automatically configure a server instance, deploy the web applications, and also automatically configure related middle-tier components such as SAS Web Server, JMS
Broker, and Cache Locator.
To use this feature, select the Configure the web application server automatically check box on the Web Application Server: Automatic Configuration page of the SAS
Deployment Wizard.
Manual Configuration
If you prefer to configure SAS Web Application Server manually, make sure the
Configure the web application server automatically check box is not selected when you use the SAS Deployment Wizard. Once the wizard completes, the Instructions.html file provides step-by-step instructions for how to configure the server manually. The instructions are customized for your deployment, including the correct host names and file system paths.
The generated Instructions.html file also includes information about installing and configuring the related middle-tier components: SAS Web Server, JMS Broker, and
Cache Locator.
Multiple Machine Installation
You can install and configure SAS Web Application Server on multiple machines to provide better performance, scalability, and high availability. This is called horizontal clustering.
You can have the SAS Deployment Wizard automatically configure the additional
instances, or configure them manually. For more information, see “Adding a Horizontal
.
48
Chapter 4 / Administering SAS Web Application Server
Understanding the SAS Web Application
Server Configuration
Server Naming
The default name for the first server instance is SASServer1_1.
The server name and instance is broken down as follows:
SASServer1
This portion identifies the server name.
_1
This portion identifies the first instance of the server. Additional instances of this server (for vertical clustering) increment the number as in _2, _3, and so on.
Your deployment might include additional managed servers. If your deployment includes a SAS solution, the web applications related to the solution might be deployed to managed servers with names like SASServer8_1 or SASServer12_1.
Your deployment might include SASServer2_1. This server instance is created when the SAS Deployment Wizard is used at the custom prompting level and enabling the multiple managed server option. This option is useful for distributing some of the web applications to the SASServer2_1 instance.
If you have configured multiple instances of a managed server, such as SASServer1_1 and SASServer1_2, then the web applications that support clustering are deployed identically to each instance. Each of these instances is a vertical cluster member. For applications that do not support clustering, only one instance is configured on the first server instance.
See Also
“Adding a Vertical Cluster Member” on page 211
Understanding the SAS Web Application Server Configuration
49
Server Directories
Configured instances of SAS Web Application Server are stored in the SAS-config-
dir\Levn\WebAppServer directory and subdirectories.
SAS-config-dir\Levn\Web\WebAppServer\SASServer1_1
This directory represents an instance of the SAS Web Application Server.
Information about some of the subdirectories is as follows:
bin
This directory includes a command for starting and stopping the server. More
information about controlling the server is described in “Understanding SAS Web
Application Server Management”
.
conf
SAS software manages the configuration files in this directory. If you modify a file, your customizations are overwritten the next time SAS software configures the server.
sas_webapps
This directory is used for the SAS web applications. SAS software manages the addition and removal of web applications from the directory.
Specifying JVM Options
For some advanced configuration procedures, you might need to change JVM options for the server.
For Windows deployments, the JVM options are specified in the SAS-config-dir
\Lev1\Web\WebAppServer\SASServer1_1\conf\wrapper.conf file and the
SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\bin\setenv.bat
file. If you have multiple instances of SAS Web Application Server, make the same changes in each of the files.
For UNIX deployments, JVM options are specified in the SAS-config-dir/
Lev1/Web/WebAppServer/SASServer1_1/bin/setenv.sh file. If you have multiple server instances, make the changes in each setenv.sh file.
50
Chapter 4 / Administering SAS Web Application Server
Deploying Web Applications
During the installation and configuration that is performed with the SAS Deployment
Wizard, the SAS web applications are automatically deployed if SAS Web Application
Server is automatically configured.

Understanding SAS Web Application
Server Management
Using the tcruntime-ctl Command
Each server instance provides a tcruntime-ctl.cmd command in the bin directory.
The command is tcruntime-ctl.sh on UNIX and z/OS.
If you use this command to start, stop, or restart a server instance, be aware that it affects only the single server instance. The command does not start or stop any middletier components that the server depends on. The command syntax is as follows: tcruntime-ctl.cmd start tcruntime-ctl.cmd stop tcruntime-ctl.cmd restart
Note:
On Windows, the status option does not indicate whether the server is running or stopped.
Using the appsrvconfig Command
Each machine that is used to run SAS Web Application Server for the SAS middle-tier includes the SAS Configuration Scripting Tools in the SAS-config-dir\Levn\Web
Understanding SAS Web Application Server Management
51
\Scripts\AppServer directory. The appsrvconfig.cmd command can be used for starting, stopping, and restarting all the SAS Web Application Server instances on the machine as well as any middle-tier components that the server depends on.
For example, the command appsrvconfig.cmd restart automatically performs the following tasks:
1 Stops all SAS Web Application Server instances
2 Stops JMS Broker
3 Stops Cache Locator
4 Starts Cache Locator
5 Starts JMS Broker
6 Starts all SAS Web Application Server instances
The actual tasks are identified in a command task file that is located in the SAS-
config-dir\Levn\Web\Scripts\AppServer\props. The file is generated and then executed. The file does not exist until the appsrvconfig.cmd command is used.
Information about using the appsrvconfig.cmd command for configuration tasks is
provided in SAS Configuration Scripting Tools on page 301
.
Using Windows Services
For deployments that use the Windows operating environment, the default action for the
SAS Deployment Wizard is to register each server instance as a service. The naming convention is similar to the following example:
SAS [Config-Lev1] WebAppServer SASServer1_1
The Windows service has the advantage of providing the server status (started or stopped), which is not available with the tcruntime-ctl.bat command line tool. In addition, the Windows service manages the service dependencies.
52
Chapter 4 / Administering SAS Web Application Server
Using SAS Environment Manager
SAS Environment Manager provides an interface that you can access with a web browser. You can start and stop SAS Web Application Server with the web interface.
When you start a server instance with SAS Environment Manager, the application indicates that the server started successfully before the server actually completes starting.
The command-line interface (tcsadmin) that is available with SAS Environment
Manager can be used for inventory and control operations. Do not use it for application management or configuring instances and groups because you can create inconsistencies with the deployment software developed by SAS.

SAS Environment Manager: User's Guide
Monitoring SAS Web Application Server
The SAS 9.4 release introduces SAS Environment Manager. A SAS Environment
Manager Agent is installed on the same machine as SAS Web Application Server and reports metrics to SAS Environment Manager.
You can access SAS Environment Manager from a URL that is similar to the following example: http://hostname.example.com:7080
Note:
The server portion of SAS Environment Manager runs in its own instance of a web application server. However, SAS Environment Manager is configured to use SAS
Logon Manager for authentication, and this requires that SAS Web Application Server is running before you can access SAS Environment Manager.

About the Cache Locator
The Cache Locator is based on VMware vFabric GemFire. The software is used by applications on server-tier and middle-tier machines to locate other members and form a data cache. When SAS Web Application Server starts, it contacts one of the locators that is specified in the sas.cache.locators JVM option to initialize communication with the distributed cache. With that information, SAS Web Application Server instances form the cache that is needed to share run-time information.
A locator is also configured on the server tier to provide access to the data cache for stand-alone client applications like the SAS Web Infrastructure Platform Scheduling
Services (wipschedbatch.bat).
54
Chapter 5 / Administering Cache Locator
Installing Cache Locator
Single Machine Deployments
In a single-machine deployment where the middle tier and the server tier are on the same machine, only one locator is installed by the SAS Deployment Wizard.
SAS Web Application Server uses the locator. If more than one instance of SAS Web
Application Server is configured, each instance uses the locator to learn about the other server instances to form the cache.
Multiple Machine Deployments
A locator is installed on the first middle-tier machine by the SAS Deployment Wizard. A locator is also installed on each server-tier machine that includes SAS Web
Infrastructure Platform Scheduling Services.
Understanding the Cache Locator
Configuration
The default location for the cache locator is SAS-config-dir\Levn\Web\gemfire
\instances\ins_port-number. Key files and directories are as follows: gemfire-locator.sh
This script exists on UNIX deployments only. It can be used with one of the following arguments: start, stop, or status.
gemfire-start-locator-sas.sh
This script exists on UNIX deployments only. Use this file to specify JVM options for
UNIX deployments.
Setting the Bind Address
55 gemfire-locator-zos.jcl
This script exists on z/OS deployments only. Use this file to specify JVM options for z/OS deployments.
gemfire.log
This is the log file for the cache locator. Be aware that it is different from the log file with the same name that is written to SAS-config-dir\Levn\Web
\WebAppServer\SASServer1_1\logs.
wrapper.conf
This file exists on Windows deployments only. It is used when you operate the SAS
[Config-Lev1] Cache Locator service. Use this file to specify JVM options for
Windows deployments.
Setting the Bind Address
When the locator is deployed on a machine that has more than one network interface, one network interface is used by default. In some cases, the network interface that is selected as the default is not the network interface that you want the locator to use.
You specify the network bind address to use for network traffic, add the -
Dgemfire.bind_address=preferred-ip-address JVM option. For information
about how to specify the options, see “Understanding the Cache Locator Configuration” on page 54
.
If SAS Web Application Server is deployed on the same machine, specify the same -
Dgemfire.bind_address=preferred-ip-address JVM option. For more
information, see Specifying SAS Web Application Server JVM Options on page 49
.

61616.
SAS middle-tier software uses the broker for Java Messaging Services (JMS). Some
SAS web applications use JMS connection factories, queues, and topics for implementing business logic. These resources are configured in SAS Web Application
Server for use by the SAS web applications.
Installing JMS Broker
The broker is installed and configured with the SAS Deployment Wizard. If you perform an automatic configuration of SAS Web Application Server, then the broker is automatically installed and configured. If you prefer to perform a manual configuration of
58
Chapter 6 / Administering JMS Broker
SAS Web Application Server, then you must install and configure the broker. The stepby-step instructions are provided in the Instructions.html file that is generated by the
SAS Deployment Wizard.
An instance of the broker is installed on the first machine that is used for the SAS middle tier. If you use the SAS Deployment Wizard to configure an additional middle-tier node on another machine, then those server instances are configured with connection information for the broker.
Understanding the JMS Broker
Configuration
The default location for the broker is SAS-config-dir\Levn\Web\activemq. Key files and directories are as follows:
bin
On UNIX deployments, the activemq command is included in this directory. You can use the start, stop, restart, or status options with the command.
On Windows deployments, use the service that is registered with Windows to manage the broker. The activemq.bat command is not configured for use with
SAS software.
data
The activemq.log file is written in this directory.
Monitoring JMS Broker
The primary user interface for monitoring the server is SAS Environment Manager.
Numerous metrics are collected from the broker.
In SAS Environment Manager, the broker is represented as host-name ActiveMQ 5.7.
Statistics for the broker itself as well as the queues and topics are also gathered.

Portal
Specify the position of the portal navigation bar in the SAS Information Delivery
Portal. You can also specify the sort order for packages that are published in the portal. You can sort packages in descending order (newest packages are at the top) or in ascending order (oldest packages are at the top).
SAS Comment Manager
The SAS Comment Manager can be used by SAS web applications to capture user comments. For example, in SAS Web Report Studio, the File Comments menu item enables users to add comments to reports and graphs.
By default, all users who can log on to an application that uses the SAS Comment
Manager can view and create comments. As an administrator, you might also want to edit and delete comments. Editing and deleting comments are considered administrative functions.
To edit and delete comments, you must belong to the predefined role, Comments:
Administrator. This role includes the capabilities in the following list. Users that have a need to edit or delete comments should be assigned to this role.
Note:
Due to possible conflicts that can occur when multiple users delete comments in the same comment thread, the best practice is to limit the number of users to just a few.
To edit or delete a comment, follow these steps:
1
Select the comment in the left pane of SAS Comment Manager.
2
To edit the comment, in the right pane, click Edit. An Edit Comment page opens in which you can make changes. When you are finished, click Save.
3
To delete the comment, in the right pane, click Delete. You are prompted to confirm the deletion.

About Internal and External Connections
The connection information for each application is stored in metadata. This information is as follows: n
Communication Protocol n
Host Name n
Port Number n
Service
76
Chapter 7 / Administering the SAS Web Infrastructure Platform
This information is used to construct a URL (for example, http://
hostname.example.com/SASBIDashboard). This information is also used by SAS applications that need to communicate with another application. In this case, the requesting application can look up the information from metadata.
By default, the information in the previous list is identified on the Internal Connection tab for each application. (In previous releases, this was the Connection tab.) In many network topologies, end users and SAS web applications can send requests to the same URL. In these cases, the External Connection tab has the Use internal
connection information check box selected, and all communication is sent to the internal connection.
Some network topologies can prevent communication between SAS web applications.
The following figure shows a sample topology that prevents applications in the SAS middle tier from accessing each other through the proxy.
Figure 7.1 Network Topology with a Firewall

In these topologies, the External Connection tab can be used to specify different connection information. This might be necessary in the following scenarios:
Specifying Connection Properties
77 n
A firewall denies access to the SAS Web Server machine that originates from the
SAS Web Application Server machine.
n
A third-party product such as IBM Tivoli Access Manager WebSEAL or CA
SiteMinder is used to protect or rewrite URLs.
The previous two items are examples of a topology or software product that interacts with SAS Logon Manager. Any change that affects access to SAS Logon Manager can require you to specify external connection information because the change can affect the call backs that occur between the applications and SAS Logon Manager.
In any network topology that prevents access to the front-end processor (identified as the proxy in the previous figure) from the SAS middle tier, you can specify different settings for the external connection. When a SAS web application accesses another application, it uses the internal connection. When a user is redirected to a URL (for example, SAS Logon Manager redirecting to SAS BI Dashboard), then the external connection information is used.
Changing Connection Properties
The Internal Connection tab in the properties dialog box for SAS applications enables you to modify the parameters for connecting to a SAS web application. The selections that are displayed on the tab determine the URL that is used to access the application's resources or services.
The following display shows the internal connection information for SAS BI Dashboard properties.
78
Chapter 7 / Administering the SAS Web Infrastructure Platform
Display 7.6 Internal Connection Tab for BI Dashboard Properties
If a SAS web application is moved to a different machine (and you are not using SAS
Web Server), you must modify the connection information. If you configured SAS Web
Server manually for HTTPS, you must change the protocol.
Changing the values for the Host Name, Port, or Service fields on the tab enables the
SAS Web Application Infrastructure Platform to redirect clients to the proper locations in a custom environment. For the host name, you can supply an IP address. If you enter an IP version 6 address, you must enclose the address in brackets.
For example: [FE80::202:B3FF:FE1E:8329]
Changing External Connection Properties
If your site changes its configuration after initial deployment, you might need to edit the external connection information parameters. One example is adding a third-party product to the network, such as IBM Tivoli Access Manager WebSEAL or CA
SiteMinder. In this case, you must route connections through the proxy. These changes must be made on the External Connection tab.

Chapter 7 / Administering the SAS Web Infrastructure Platform
Configuring Auditing for SAS Web
Applications
Overview of Auditing
SAS web applications and other SAS middle-tier services provide auditing features.
Depending on the application and its configuration, these auditing features can record all actions performed both by the direct users of the system and by the system itself.
Some applications might provide a more complete audit, detailing not only the actions that are performed but also the states of the objects that are affected by those actions.
Log on, log off, and unsuccessful log on attempts create audit records for all deployments. Additional actions that can be audited for SAS Web Infrastructure
Platform are described in this section. If a SAS solution is installed, see the solution documentation for information about additional actions that can be audited.
Audit Record Storage
Audit records are stored in the SAS Web Infrastructure Platform database. These audit records are stored in two relational tables, SAS_AUDIT and SAS_AUDIT_ENTRY. Two additional tables, SAS_AUDIT_ARCHIVE and SAS_AUDIT_ENTRY_ARCHIVE, provide archival audit data.
Do not access the tables directly for audit reporting. The SAS Web Administration
Console provides an interface for viewing log on, log off, unsuccessful log on attempts, and last user logon information.
Depending on the auditing configuration of the deployed SAS applications, audit records can contain different types of audit information. However, all audit records contain the following information: n user ID that performed the audited action.
n action that occurred. This is stored as an action code.
n data and time that the audited action occurred.

Guidelines for Auditing the SAS Middle Tier
The auditing process in the SAS middle tier is designed to be efficient for both processing time and storage. However, you might want to limit the number of audited events to minimize any effect on performance and minimize the size of the audit trail.
The SAS middle tier auditing features provide the tools to help you balance the need to gather sufficient security or historical records with the ability to store and process it.
Consider these guidelines to make efficient use of the SAS middle tier auditing features: n
Evaluate the purpose of auditing an action. Make sure that records for an audited action can be used to serve a business purpose.
n
When auditing for security, audit generally and then audit specifically. Analyze the records from general audit options to provide the basis for targeting specific audited actions.
n
When auditing for historical information, audit for actions that are important to your business only. Avoid cluttering valuable audit records with less relevant audited actions. Narrowing the focus to valuable actions also reduces the amount of audit trail administration.
n
Align the audit requirements to the most strictly regulated application. If your SAS deployment includes a number of SAS applications, the applications might have varying requirements. Make sure that the audited actions match the most strictly regulated application.
When auditing is enabled and audit records are generated, the audit trail size increases according to two factors: n the number actions that are enabled for auditing n how frequently the audited actions are performed
If the SAS Web Infrastructure Platform database becomes completely full and audit records cannot be inserted, the audited actions cannot be successfully executed until the audit trail is purged. The system administrator must control the rate of increase and size of the audit trail. To control the size of the audit trail, consider the following strategies:
82
Chapter 7 / Administering the SAS Web Infrastructure Platform
n
Be selective about which actions are enabled for auditing. If the number of audited actions is reduced, then unnecessary and useless audit records are not generated and are not stored in the audit trail.
n
Design archive rules to move important, but not critically important, information out of the audit trail. This process archives the audit records of interest and removes
them from the main audit table. For information about archiving, see “Archive
Process for Audit Records” on page 83
.
n
Purge the audit archive tables as needed.
Enable Auditing for Additional Services
All SAS products that include the SAS Web Infrastructure Platform provide audit records for logon, log off, and unsuccessful log on attempts. Other standard services can also be audited: n mail service n content service n job execution service n workspace service n scheduling service n impersonation service
To enable auditing for any of these services, follow these steps:
1 Edit the
SASHOME\SASWebInfrastructurePlatform\9.4\Static\wars
\sas.wip.services\WEB-INF\spring-config\aop-config.xml file.
2 Review the comments to locate the service that you want to audit. Each of the services is commented out in the initial deployment. The following example shows the job execution service:
<!-- Job Execution Service auditing
<bean class="com.sas.svcs.aop.auditing.jes.SuccessfulSubmitJobAuditAdvice">
Configuring Auditing for SAS Web Applications
83
<property name="auditRecorder" ref="auditService" />
</bean>
3 Add closing comment markup and then remove the original closing comment markup (––>) from the bottom of the code block. Save your changes.
4 Rebuild the SAS Web Infrastructure Platform with the SAS Deployment Manager.
Note:
Subsequent upgrade activities can overwrite this file. For example, if you later install a maintenance release that includes aop-config.xml, then you must repeat this procedure.
5 Redeploy the SAS Web Infrastructure Platform Services web application
(sas.wip.services9.4.ear).
Enabling auditing for other SAS applications requires editing different files, but the steps are similar to the previous procedure. For example, auditing for SAS Workflow is controlled with the SASHOME\SASWebInfrastructurePlatform\9.4\Static
\wars\sas.workflow\WEB-INF\spring-config\aop-config.xml file.
Archive Process for Audit Records
Once the audit features are enabled, records are added to the SAS_AUDIT and
SAS_AUDIT_ENTRY tables. The records can be archived to the
SAS_AUDIT_ARCHIVE and SAS_AUDIT_ENTRY_ARCHIVE tables. An archive job is used to control which records to archive. The archive job reads the archive rules in the
SAS_AUDIT_ARCHIVE_RULE table. The archive job always starts when SAS Web
Infrastructure Platform Services starts. In addition, the default archive job is scheduled to start every Monday at the start of day, but the archive job schedule can be configured.
84
Chapter 7 / Administering the SAS Web Infrastructure Platform
The following table describes the columns in table SAS_AUDIT_ARCHIVE_RULE.
Rows must be added to this table to identify the objects, actions, and age for the archive job to process.
Table 7.3 SAS_AUDIT_ARCHIVE_RULE Column Description
Column Name
OBJECT_TYPE_ID
ACTION_TYPE_ID
FREQUENCY_NO
Description
Object type. Each object type is assigned an ID in table
SAS_TYPE_OBJECT.
Type of change. Each action type is assigned an ID in table
SAS_TYPE_ACTION.
A numeric value in milliseconds. Records that meet the criteria for OBJECT_TYPE_ID and ACTION_TYPE_ID, and are also older than this value, are archived.
To control the archive job schedule, you can add a JVM option to SAS Web Application
Server. The -Dsas.audit.archive.cron JVM option can be used to specify the schedule. The schedule is set with a syntax that is similar to cron:
-Dsas.audit.archive.cron="second minute hour day_of_month month day_of_week"
The following example schedules the archive job to run each day at midnight:
-Dsas.audit.archive.cron="0 0 0 * * *"
You can confirm the archive job runs and reads the archive rules by adding a logging context to com.sas.svcs.audit at the INFO level.
The following table identifies the common object types and actions that you might want to include in the SAS_AUDIT_ARCHIVE_RULE table:

Chapter 7 / Administering the SAS Web Infrastructure Platform
Performing Server Maintenance
Overview
Tasks such as making changes to the metadata, restarting a metadata server, restarting the object spawner, or restarting a web application can be performed safely only when users are not logged on to applications or when new users are prohibited from logging on to the applications.
You can use the console to enable session draining for a SAS Web Application Server instance. This prevents new sessions from being sent to the server instance. You can use this feature as one step in a sequence of other tasks to prepare the system for maintenance.
The SAS Web Administration Console cannot stop, pause, or start servers. For instructions about system maintenance tasks such as stopping, pausing, or starting servers, see the SAS Intelligence Platform: System Administration Guide.
Enable Session Draining
To enable session draining, follow these steps:
1 Connect to the load balancer manager at http://
saswebserver.example.com/balancer-manager.
Note:
By default, the load balancer manager is accessible from the same host as
SAS Web Server. Modify WebServer\conf\extra\httpd-info.conf to enable connections from other machines.
2 On the load balancer manager page, select the worker URL to drain, enable the
Drain option, and click Submit.
3 In the SAS Web Administration Console, select Environment Management
Server Maintenance in the navigation pane.
4
On the Server Maintenance page, select the check box for the server to drain sessions from.
Using the SAS Web Administration Console
91
Note:
If a server does not run an application that provides middle-tier services, then the server is not listed. This is because there is no reason to redirect connections away from that server.
5 Click the action menu in the heading of the last column, and select Drain
Sessions.
Existing sessions on the server continue to work, but new sessions are not directed to the server. You can monitor the progress of session draining with SAS Environment
Manager.
In SAS Environment Manager, monitor the hostname tc Runtime SASServern_m resource. Use the Views Application Management page to view the number of sessions. For more information, see the Help or SAS Environment Manager: User’s
Guide.
Note:
The sessions for the SAS BI Dashboard Event Generation application do not reach zero.
New sessions are accepted once you restart the server instance.
Managing Notification Templates and
Letterheads
About Notifications
Applications that are part of the SAS Web Infrastructure Platform can send event-driven notifications to users. When an event occurs, the application uses the notification template that is associated with that event to create an e-mail message and send it to the appropriate users. SAS Workflow Studio is an example of an application that uses notifications.
SAS provides standard notification templates for the SAS Web Infrastructure Platform applications that you have licensed. You can use SAS Web Administration Console to do the following: n customize the wording and format of the standard templates n define customized letterheads to be incorporated into notifications
92
Chapter 7 / Administering the SAS Web Infrastructure Platform
n create new templates and delete existing ones n activate a previous version of a notification template or letterhead

Managing Web Infrastructure Platform
Privileges and Roles
About Web Infrastructure Platform Privileges and Roles
Some SAS applications (such as SAS Workflow Studio) use Web Infrastructure
Platform privileges and roles to control the availability of features to users and groups.
A privilege represents a specific action in an application. Privileges can affect the visibility of certain application features (such as menu items, tabs, and buttons) to users.
Using the SAS Web Administration Console
95
A role is a collection of privileges. Administrators grant privileges to users or groups by making them members of roles.
There is no order of precedence for privileges. A user has a privilege if he or she is a member of any role that provides that privilege.
Several predefined roles are provided in a new deployment. For example, the ADMIN role makes the authorization tasks visible in SAS Web Administration Console. The
SAS Administrative User is the only initial member of the ADMIN role. Other predefined roles are provided for specific applications. For information about those roles, see the application’s administration documentation.
Note:
The Web Infrastructure Platform roles and privileges are separate and distinct from the metadata-layer roles and capabilities that are administered in SAS
Management Console.
Assign One or More Roles to a User or Group
To assign one or more roles to a user or a group, follow these steps:
1 Select Environment Management Authorization Assign Roles in the navigation pane.
2
On the Principal Type page, select Users or Groups. Click Next.
3
On the Choose Principal page, select the user or group to which you want to assign roles. The drop-down list displays users and groups that are registered in SAS metadata. After making a selection, click Next.
4
On the Choose Roles page, select the check box for each role that you want to assign to the user or group. To remove a role assignment, clear the check box.
5
Click Finish to save your changes.
Use Bulk Assign to Assign a Role to Multiple Users or Groups
You can use the bulk assign feature to assign a single role to multiple users or groups.
Follow these steps:
96

4 Click Finish to save your changes.
Managing Web-layer Permissions
About Web-layer Permissions
Some SAS applications (such as SAS Workflow Studio) use SAS Content Services to manage content. Web-layer permissions control users’ access to the folders and documents that make up this content. Five permissions are supported: Read, Write,
Create, Delete, and Administer. Not all permissions are applicable to all objects. For
Using the SAS Web Administration Console
97 information about how a particular application uses these permissions, see the administration documentation for the application.
In general, permissions for these folders and documents are managed by the SAS applications that use them. SAS Web Administration Console enables administrators to review the permissions and, as necessary, to update them. You should use SAS Web
Administration Console to update web-layer permissions only when directed to do so by
SAS Technical Support.
Note:
Some SAS applications use the SAS Content Server (instead of SAS Content
Services) to manage content. To manage SAS Content Server permissions, see
“Administering the SAS Content Server” on page 136
.
Precedence in Web-layer Permissions
Authorization decisions are based on where web-layer permissions are set and to whom they are assigned. The precedence principles are as follows: n
A permission that is set directly on an object has precedence over a permission that is inherited from a parent object.
n
At any particular level in the object hierarchy, a permission that is assigned to a user has precedence over a permission that is assigned to a group. n
If a user has a grant from one group and a denial from another group, the outcome is a denial.
Applications use the following process to make authorization decisions:
1 Examine any direct access controls on the target object.
a If the requesting user has a direct grant or denial, that determines the outcome. b If a group to which the requesting user belongs has a direct denial, the outcome is a denial.
c If a group to which the requesting user belongs has a direct grant (and no relevant group denial is found), the outcome is a grant.
2 Examine any direct access controls on the object’s immediate parent, following the same process as in step 1.
98
Chapter 7 / Administering the SAS Web Infrastructure Platform
3 Continue moving up the inheritance hierarchy, parent-by-parent, until a relevant direct access control is found.
4 If the top of the hierarchy is reached and no relevant access control is found, the outcome is a denial.
Reviewing and Setting Web-layer Permissions
You can use SAS Web Administration Console to review and update permissions for folders and documents that are managed by SAS Content Services.
CAUTION! In general, permissions for these folders and documents are
managed by the SAS applications that use them. You should use SAS Web
Administration Console to update permissions only when directed to do so by
SAS Technical Support.
To review or update permissions on a folder or document that is managed by SAS
Content Services, follow these steps:
1 Select Environment Management Authorization Permissions in the navigation pane.
2
The Web Authorization: Access Controls page displays content folders and objects in a tree format. Click the plus icons to expand the nodes, and use the scroll bars as needed to view the expanded tree.
3
Click the folder or object of interest to select it. The Properties section displays the path, object type, and owner information for the selected folder or object, and the
Direct Access Controls section displays the current permission settings.
4
In the Direct Access Controls section, select the check box to select or clear the option Child objects can inherit these settings.
5
For each user or group that is displayed, use the drop-down boxes as needed to modify the permission settings.
6
To specify permissions for additional users or groups, follow these steps:
Using the SAS Web Administration Console
99 a In the first column of the last row of direct access controls, select the appropriate principal type (User or Group). From the second drop-down box, select the user or group for which you want to assign permissions. (The drop-down list displays users and groups that are registered in SAS metadata.) Use the drop-down boxes in columns three through seven to assign settings for each permission.
b To specify permissions for another user or group, click the plus icon (+) at the end of the last row. In the new row, select the principal type, the user or group, and the appropriate permission settings. To specify permissions for more users and groups, repeat this step as needed.
7 When you are finished, click Save.
Viewing Information about Web Applications
The SAS Web Administration Console provides configuration information about the SAS web applications that are installed and configured at your site. This information is also available in SAS Management Console. However, SAS Web Administration Console enables you to view the information from any machine with a web browser, without the need to have SAS Management Console installed on the machine.
To display a list of configured web applications, expand the Application Management node in the navigation pane. When you click the name of an application, the right pane displays information under the following headings:
Application Settings displays settings that are currently configured for the application. For example, SAS
Information Delivery Portal settings include the locale that is in use, the location where portlets are deployed, the e-mail host, and default settings for various user preferences.
You cannot change any of the application settings here. To change settings, use the
Application Management Configuration Manager plug-in in SAS Management
Console.

About SAS Deployment Manager
The SAS Deployment Manager enables a SAS administrator to perform the following tasks that are typical for the middle tier:
102
Chapter 8 / Administering SAS Web Applications
n
Rebuild Web Applications. You can rebuild web applications that have previously been configured but whose configuration has changed. This option rebuilds the web
application based on the current configuration. See “Rebuilding the SAS Web
.
n
Redeploy Web Applications. You can redeploy web applications that have rebuilt.
See “Redeploying the SAS Web Applications” on page 107
.
n
Remove the existing configuration. You can remove the product configuration for one or more products in the deployment. This option enables you to remove the product configuration for an application that you are no longer using or that you are moving to another machine. You can then use the SAS Deployment Wizard to reinstall or reconfigure the application. For details, see “Removing a SAS
Configuration” in the SAS Intelligence Platform: Installation and Configuration Guide.
Note the following about removing a configuration: o
Installed products are not removed.
o
If you remove the configuration for the SAS Information Delivery Portal, do not select the Remove all User Content option unless you have made a backup copy of the content repository. If you choose this option, you must re-create the content later from your backup. When you choose to remove portal content, all pages, portlets, and other items created by the users are removed. o
If you remove the configuration for the Web Infrastructure Platform, the contents of the SAS Content Server repository (located in the SAS-config-dir
\Lev1\AppData\SASContentServer\Repository directory) are not deleted. If you do not need the contents of this directory, you should manually delete the contents before rebuilding the Web Infrastructure Platform with the
SAS Deployment Manager.
Access the SAS Deployment Manager by running the SAS-install-dir
\SASDeploymentManager\9.4\sasdm.exe command. On UNIX and z/OS operating environments, the command is sasdm.sh.

103
Rebuilding the SAS Web Applications
When to Rebuild the SAS Web Applications
The Rebuild Web Applications option of the SAS Deployment Manager provides an automated way to rebuild the web applications that are deployed in your environment.
You should rebuild the web applications in the following situations: n
You might need to rebuild applications that you have reconfigured. For example, if you change the HTTP time-out interval for an application, then you should rebuild the application.
n
Note:
This administration guide informs you when an application must be rebuilt after reconfiguration.
Rebuild an application after you change the Java security configuration for the application.
n
If a custom theme is created for your organization, then rebuild the SAS Web
Application Themes.
n
If custom content is created, then add files to the WAR directory and rebuild the application to which the custom content applies. For example, to create custom forms for SAS Stored Process, place the file for the EAR or the WAR in the SAS-
config-dir\Lev1\Web\Common
\SASServer1\SASStoredProcess9.4\CustomContent\ears
\sas.storedprocess\input directory. Then, use the SAS Deployment Manager to rebuild the SAS Stored Process application.
n
If custom portal content is created, such as a custom portlet, then rebuild the SAS
Information Delivery Portal. For more information, see “Rebuild Web Applications” on page 104
.
n
Rebuild SAS Help Viewer for Midtier Applications after your initial deployment if you install or upgrade a SAS web application that offers online Help. (SAS Help Viewer
104
Chapter 8 / Administering SAS Web Applications
for Midtier Applications combines SAS Help Viewer for the Web software with various help content into its EAR file.)
The following web applications use SAS Help Viewer for Midtier Applications: o
SAS Information Delivery Portal Help o
SAS Web Report Studio Help o
SAS Web Report Viewer Help o
SAS BI Dashboard Help o
SAS Comment Manager Help n
After installing a maintenance release or hot fixes, rebuild the web applications that were updated at your site. Follow the instructions in the maintenance documentation or the hot fix instructions. Because the web applications are rebuilt, you might lose any customizations that you added after the initial deployment.
Rebuild Web Applications
The Rebuild Web Applications option in the SAS Deployment Manager enables you to rebuild one or more web applications. The rebuild process updates two directories for each rebuilt web application: n SAS-config-dir\Lev1\Web\Staging. An EAR or WAR file for each rebuilt application is placed in this directory.
The approximate size of the collection of applications for SAS Enterprise Business
Intelligence is 4 GB.
n SAS-config-dir\Lev1\Web\Staging\exploded. An exploded version of each rebuilt application is placed in this directory.
Note:
You can delete any unwanted directories in the exploded directory to save disk space.
To rebuild one or more web applications, follow these steps:
1 The web application server can be running or stopped.

Redeploying the SAS Web Applications
About Redeploying Web Applications
When the SAS Deployment Manager rebuilds SAS web applications, the rebuilt EAR files are placed in the SAS-config-dir\Lev1\Web\Staging directory. All EAR files
108
Chapter 8 / Administering SAS Web Applications
are placed in a single directory even if your deployment includes multiple web application servers (for example, SASServer1_1 and SASServer2_1).
If you have web application servers that were installed and configured by the SAS
Deployment Wizard in your environment, make a note of the server names and the web applications that are installed on each server. For example, if six applications are located on SASServer1_1 and three applications are located on SASServer2_1, make a list of the applications that are installed on each of these servers. Alternatively, you can refer to your Instructions.html file, which specifies the following: n the list of web applications to be deployed n the location of the applications n the web application server where each application should be deployed
When you redeploy the SAS web applications, you can refer to your list or the
Instructions.html file, to ensure that you redeploy each application to the correct server.
Redeploy Web Applications
Steps to Perform with the SAS Deployment Manager
The SAS Deployment Manager manages the SAS web applications as EAR files but the applications are deployed as WAR files.

Before the SAS Deployment Manager redeploys a web application, it creates backups of the existing version and the context file. The backups are as follows: n n
Application backups are in the SAS-config-dir\Levn\Web\WebAppServer
\SASServer1_1\sas_webapps\Backup directory.
Context file backups are in the SAS-config-dir\Levn\Web\WebAppServer
\SASServer1_1\conf\Catalina\localhost\Backup directory.
A timestamp is appended to the web application directory and context file to indicate when the backup was performed. If you frequently redeploy web applications, you can consume disk space. You can delete backup files that are no longer needed.
Additional Steps for Horizontal Clusters
To redeploy web applications on additional machines in a horizontal cluster, follow these steps:
1 Stop the SAS Web Application Server instances on the additional machines.
2 Copy the updated application EAR and WAR files from the primary machine to the staging directory on the additional machines.
110
Chapter 8 / Administering SAS Web Applications
The staging directory is typically SAS-config-dir\Levn\Web\Staging.
3 Use the appsrvconfig command on each additional machine to undeploy and redeploy the web applications: appsrvconfig.cmd -e run undeploy application application-name server SASServer1 appsrvconfig.cmd -e run deploy application application-name server SASServer1
The command is located in the SAS-config-dir\Levn\Web\Scripts
\AppServer directory. On UNIX deployments, the command is
appsrvconfig.sh. For more information, see
“SAS Configuration Scripting Tools” on page 301
.
4 Start the SAS Web Application Server instances on the additional machines.
5 Restart SAS Web Server.
Reconfiguring the Web Application
Server
Reconfigure your web application server when any of the following conditions apply: n
A new SAS web application is added to your deployment.
n
A web application is unconfigured and reconfigured.
n
A software bundle is added to an existing configuration.
It is important to reconfigure your web application server in the same manner that it was initially configured. If you manually configured SAS Web Application Server when you initially deployed, then configure it manually again. If the SAS Deployment Wizard automatically configured your web application server, then choose the automatic configuration option again.
If the environment was initially configured with the Web Application Server: Multiple
Servers option in the SAS Deployment Wizard, then reconfigure SAS Web Application
Server by using the Custom path in the SAS Deployment Wizard and selecting the Web
Administering Logging for SAS Web Applications
111
Application Server: Multiple Servers again. Reconfiguring SAS Web Application
Server can cause the loss of some customizations, and they need to be reapplied.
For more information, see “Managing Your SAS Deployment” in the SAS Intelligence
Platform: Installation and Configuration Guide.
Administering Logging for SAS Web
Applications
Logging for SAS Web Applications
The SAS web applications use log4j to perform logging. As each web application begins running, the log4j configuration file for the application is read from SAS-config-dir
\Lev1\Web\Common\LogConfig. After the log4j configuration file is read, the applications that permit dynamic logging changes check for modifications that were set with the SAS Web Administration Console.
The following table identifies if customizations can be performed by editing the log4j configuration file, using dynamic logging changes, or both:

Changes
For information about the log4j configuration file, see
http://logging.apache.org/log4j/ index.html
and
http://logging.apache.org/log4j/1.2/manual.html
.
Logging categories use the fully qualified class name of the class where the logging message originates. Categories for the following classes are common to all SAS web applications: n com.sas
n com.sas.services
n com.sas.services.deployment
n com.sas.services.discovery
n com.sas.services.util
Change the Logging Levels
Logging Level Descriptions
Log4j files offer many levels of logging detail. Enabling a level also enables the less detailed levels above the selected level. The default level is set to WARN, which means that WARN, ERROR, and FATAL messages are recorded. In large-scale deployments, the size of the log file can grow rapidly when INFO messages are enabled. However, you might want to enable the INFO messages during the development and testing phases.
CAUTION! Excessive logging can degrade performance. Therefore, you should
not use the DEBUG level unless you are directed to do so by SAS Technical
Support.
Administering Logging for SAS Web Applications
113
If you need to debug a problem, it is recommended that you dynamically change the log output temporarily.
Here is a brief description of each level:
ALL enables all logging.
TRACE displays finer-grained informational events than DEBUG.
DEBUG displays the informational events that are most useful for debugging an application.
INFO displays informational messages that highlight the progress of the application.
WARN displays potentially harmful situations.
ERROR displays error events that might allow the application to continue to run.
FATAL displays very severe error events that might cause the application to end abnormally.
OFF disables all logging.
Using log4j Files
To modify the logging level by editing the log4j files, follow these steps:
1 Change directory to SAS-config-dir\Lev1\Web\Common\LogConfig and edit the log4j file for the application to modify.
2 Locate the category for the class that you want to modify and modify the value of the priority parameter:
<category
additivity="false"
name="com.sas.workflow">
114
Chapter 8 / Administering SAS Web Applications
<priority

Chapter 9 / Administering SAS Logon Manager
About SAS Logon Manager
The SAS Logon Manager is a web application that handles all authentication requests for SAS web applications. As a result, users see the same logon page when they access the SAS web applications.
The purpose of the SAS Logon Manager is to authenticate and direct a successful logon to the appropriate web application. The application also serves as the central point for handling changes to authentication mechanisms, such as the addition of Windows SSPI or third party single sign-on products.
When a user successfully authenticates to SAS Logon Manager, the user receives a global single sign-on session. This is introduced in the SAS 9.4 release. The global single sign-on session enables the user to access all the SAS web applications that the user is authorized to use, without a credential challenge for each web application. The global single sign-on time-out is independent of the web application time-out interval.
For more information, see the Log user off on timeout policy in Configuring Middle
Customizing Log On, Log Off, and Time
Out Messages
Step 1: Customize the Message
You can configure a customized message that is displayed when users of SAS web applications log on, log off, or the session reaches the time out interval. To enable the display of a custom message, follow these steps:
1
In the SASHOME\SASWebInfrastructurePlatform\9.4\Static\wars
\sas.svcs.logon\WEB-INF\view\jsp\default\ui directory, edit the files that you want to change: n logon_custom.jsp
Customizing Log On, Log Off, and Time Out Messages
121 n logoff_custom.jsp
n timeout_custom.jsp
Each file is included as part of an HTML page. Therefore, each should contain valid
HTML code.
2 Save your changes.
Step 2: Configure SAS Application
Infrastructure
1
Log on to SAS Management Console.
2
On the Plug-ins tab, select Application Management Configuration Manager, right-click SAS Application Infrastructure, and select Properties.
3
Click the Settings tab.
4
Select Policies in the left pane.
5
Set any or all of these properties to Yes: n
Display custom logon message n
Display custom logoff message n
Display custom timeout message
Click OK.
6
Exit from SAS Management Console.
Step 3: Rebuild and Redeploy SAS Web
Infrastructure Platform
1
Rebuild the SAS Web Infrastructure Platform with the SAS Deployment Manager.
122
Chapter 9 / Administering SAS Logon Manager
2 Redeploy the SAS Web Infrastructure Platform with SAS Deployment Manager.
(Stop SAS Web Application Server before performing the redeploy.)
3 Verify that the custom logoff message is displayed when you log on and log off from the web application.
Step 4: Back Up the Customized Files
Back up the customized files from the SASHOME\SASWebInfrastructurePlatform
\9.4\Static\wars\sas.svcs.logon\WEB-INF\view\jsp\default\ui
directory.
If a maintenance release is applied to the system, those files are overwritten and your changes are lost. After applying a maintenance release, restored the customized files.
Displaying a Warning Message for
Inactive User Sessions
Understanding Inactive Users and Time-out
Warnings
Inactive users are directed to a time-out page when their sessions are inactive for 30 minutes or for the amount of time specified by the administrator in the web.xml files.
(You can change this behavior to log users off instead by setting the Log user off on
timeout policy.)
Before being directed to the time-out page, you can alert users about the impending time-out by displaying a warning message. When the warning message is displayed, users can click the Continue button to activate and extend their sessions. The following applications support the display of a warning message: n
SAS Web Report Studio n
SAS Information Delivery Portal
Displaying a Warning Message for Inactive User Sessions
123 n
SAS BI Dashboard n
SAS Package Viewer n
SAS Shared applications n
SAS Preferences n
SAS Web Administration Console n
SAS Stored Process
If you want to specify a different session time-out interval for each SAS application, complete this task for each SAS application by defining the
App.SessionTimeoutWarningInterval property and a custom value in minutes.
Step 1: Configure the SAS Application
Infrastructure
To configure the SAS application infrastructure:
1
Log on to SAS Management Console.
2
On the Plug-ins tab, select Application Management Configuration Manager, right-click SAS Application Infrastructure, and select Properties.
3
In the SAS Application Infrastructure Properties dialog box, click the Advanced tab.
Step 2: Set the Interval for the Inactive
Session Warning
This set of steps is optional. If you do not specify a value for the
App.SessionTimeoutWarningInterval, a default value of 5 minutes is used.
To set the interval for the inactive session warning:
1
Click Add to define a new property.
2
Enter App.SessionTimeoutWarningInterval in the Property Name field.
124
Chapter 9 / Administering SAS Logon Manager
3 Enter the number of minutes for the inactive session warning in the Property Value field and click OK.
Step 3: Enable the Inactive Session Warning
To enable the inactive session warning:
1 Click Add to define another new property.
2 Enter Policy.DisplaySessionTimeoutWarning in the Property Name field.
3 Set the value to true and click OK.
To enable these properties to take effect, restart the web application server.
Configuring the HTTP Session Time-out
Interval
A session time-out interval logs off users' inactive sessions after a specific period of time that is defined in the web application server configuration. The default value for a session time-out interval is 30 minutes. You can customize the session time-out interval for your environment by modifying one or more of the web.xml files, and specifying a different time-out interval.
Be aware that reaching the time-out limit for an application does not end the user’s global single sign-on session unless the Log user off on timeout policy is set to Yes.
For more information, see Configuring Middle Tier Security Policies.
To specify a session time-out interval, follow these steps:
1
Use the table that follows this procedure to identify the files to modify.
2
Modify the following code in the appropriate files:
<session-config>
<session-timeout>time-out-interval</session-timeout>
</session-config>
Configuring the HTTP Session Time-out Interval
125
Replace time-out-interval with the time-out interval in minutes. As a recommendation, the number should be no smaller than 5.
When you are finished, save and close the file.
3 Use the SAS Deployment Manager to rebuild the modified SAS web applications.
4 Use the SAS Deployment Manager to redeploy the modified SAS web applications.
The following table lists the file or files that should be modified to specify a time-out interval for each web application.

Configuring the Global Single Sign-On Time-out Interval
129
Configuring the Global Single Sign-On
Time-out Interval
Understanding the Time-out Interval
The time-out interval for the global single sign-on is different from the HTTP session time-out interval that is set in the web.xml file for web applications. The default HTTP session time-out interval is 30 minutes. When it is met, the web application ends the
HTTP session. However, the default value for the global single sign-on time-out interval is 12 hours. If the user accesses a timed-out web application within that interval, or any other SAS web application, a new HTTP session is created.
TIP
This behavior can be changed so that reaching an HTTP session time-out causes the global single sign-on session to time-out as well. Set the Log user off on
timeout policy is set to Yes. For more information, see Configuring Middle Tier
One area where the HTTP session time-out and global single sign-on time-out are similar is that they both are reset when a user accesses an application.
Considerations for Changing the Time-out
Interval
The interval should be short enough to alleviate security concerns that the single signon session remains available for too long.
The interval must be long enough that users do not reach the time-out interval while they are using the application. If a user reaches the global single sign-on time-out interval, the user must provide credentials and reauthenticate.
130
Chapter 9 / Administering SAS Logon Manager
Specifying a Different Time-out Interval
If you choose to use a different value than the default, 12 hours, then specify the number of milliseconds in the -Dsas.tgt.expiration.period=inverval-in-
milliseconds JVM option.
You need to specify this option for the instances of SAS Web Application Server that are used for running SAS Logon Manager only.
Windows Specifics:
Add the JVM option to the SASServer1_1\conf
\wrapper.conf file.
UNIX Specifics:
Add the JVM option to the SASServer1_1/bin/setenv.sh file.

Disabling Concurrent Logon Sessions
The default behavior for the SAS Logon Manager and the other SAS web applications is to permit multiple logon sessions. However, it is possible to configure an advanced middle-tier security policy to prevent multiple logon sessions. When this policy is active, users can log on to one SAS web application at a time. When users use the Log Off link that is provided in the application banner, the logon session is destroyed, and users can log on to a SAS web application again.
You must specify the concurrent logon session behavior: deny
When you specify deny, the user receives a message from SAS Logon Manager that a session is already active. The user cannot log on until the existing session expires or an administrator uses the SAS Web Administration Console to Force Log Off the user.
logoff
When you specify logoff, the existing session is logged off and the user is logged on to the requested web application.
To disable concurrent logon sessions, follow these steps:
1 Log on to SAS Management Console.

About the SAS Content Server
The SAS Content Server is a content repository that stores digital content (such as documents, reports, and images) created and used by SAS client applications.
Examples of such content include reports and documents created by users of SAS Web
Report Studio and the SAS Information Delivery Portal.
The Web Distributed Authoring and Versioning (WebDAV) protocol is currently the main method used to access the SAS Content Server. In addition to the basic features of
HTTP, the WebDAV protocol is an extension to HTTP and provides Write access, version control, search, and other features.
The SAS Content Server is a web application and starts when the web application server is started.
Three JVM options are related to the SAS Content Server deployment. In the event that the deployment of SAS Content Server changes, the JVM options can be used to set the new values.

-Dsas.scs.repository.dir
Specify the path to the repository. The specified directory is used for indexes and metadata. The digital content is stored in a relational database.
Moving Content or Backing Up the SAS Content Server
137
SAS Content Server Storage
The SAS Content Server uses a database for storage. SAS Content Server uses the same database that is used by the SAS Web Infrastructure Platform. The default configuration for the SAS Web Infrastructure Platform is to use the SharedServices database instance on the SAS Web Infrastructure Platform Data Server. However, the
SAS Web Infrastructure Platform can be configured to use a third-party vendor database such as Oracle, MySQL, PostgreSQL, DB/2, SQL Server, or Teradata.
When a third-party vendor database is used, make sure that the database is configured to accept large binary objects such as documents and images. For example, on
MySQL, the max_allowed_packet variable must be set at least as large as the largest binary object in the SAS Content Server repository.
Moving Content or Backing Up the SAS
Content Server
The SAS Content Server should be backed up whenever the metadata server is backed up. For instructions about how to back up the SAS Content Server, see “Best Practices for Backing Up Your SAS System” in the SAS Intelligence Platform: System
Administration Guide.
Use the WebDAVDump and WebDAVRestore utilities to: n
Back up specific locations such as a subset of the WebDAV content.
n
Create a backup for input to a system other than the SAS Content Server.
n
Move content from one SAS Content Server to another one.
n
Share content that is available in the SAS Content Server.
For instructions about using the WebDAVDump and the WebDAVRestore utilities, see
SAS Note 38667.
138
Chapter 10 / Administering the SAS Content Server
Deploying Content Manually to the SAS
Content Server
Overview
SAS web applications such as the SAS Information Delivery Portal and SAS Web
Report Studio require the availability of content for its users. The SAS Content Server provides a WebDAV content repository that stores digital content (such as documents, reports, and images) that is created and used by SAS client applications.
To enable the availability of the content in the SAS Content Server, you can load content, update existing content, and adjust web applications that store SBIP URLs.
These tasks can be automated or they can be performed manually.
The following table shows the choices available in the SAS Deployment Wizard, and the results or manual tasks that follow these choices.

The following table shows the files associated with loading content to the SAS Content
Server or updating content. The filename for the batch or script file includes the order number.
Security Considerations for SAS Content
Server Scripts
The scripts that are described in this section for loading content, updating content, and adjusting URLs use the SAS Administrator and SAS Trusted User credentials. For deployments that performed a manual deployment of the SAS web applications, these scripts include the user IDs and an encoded form of the password. For deployments that performed an automatic deployment of the SAS web applications, the scripts include the user IDs, but do not include the passwords in any form.
Passwords in these files, whether added by the SAS Deployment Wizard, or by a SAS administrator, are not updated with the Update passwords feature of the SAS
140
Chapter 10 / Administering the SAS Content Server
Deployment Manager. Running the scripts with an expired password, or no password, provides a log result like the following example:
Output 10.1 Log File Example for Invalid Credentials

If you need to update or add a password, use the PWENCODE procedure. The following code example shows how to generate the encoded form of the password
changeit. Copy and paste the result into the scripts.
Example Code 10.1 PWENCODE Procedure Example
proc pwencode in="changeit" method=sas002; run;
The SAS log shows the value to copy and paste into the script:
{SAS002}4DE4CF4F130AC6BE4A6934E0596C8222
After you run the scripts, remove the encoded form of the passwords from the scripts as an additional security measure.
Load Content Manually to the SAS Content
Server
If you deploy SAS web applications manually, you need to load content manually to the
SAS Content Server. For information about how to load content manually for SAS web applications, see your Instructions.html file.
Use the following batch file or shell script to load content manually: n
On Windows:
Deploying Content Manually to the SAS Content Server
141 n
SAS-config-dir\Lev1\Web\Utilities\manualLoadContent-
OrderNumber.bat
On UNIX and z/OS:
SAS-config-dir/Lev1/Web/Utilities/manualLoadContent.sh-
OrderNumber.sh
If web applications were deployed manually, this script contains the credentials for the
SAS Administrator, as well as the SAS Trusted User. The password is always encrypted in the file. After loading content successfully, remove credentials for the SAS
Administrator and the SAS Trusted User.
If web applications were deployed automatically, the script does not contain the required credentials. You must manually enter the required credentials in this script file.
Update Content Manually for the SAS
Content Server
If you deploy updated SAS web applications manually, you must manually update the
DAV content in the SAS Content Server. For more information, see your
UpdateInstructions.html file, which is located in the SAS-config-dir /Lev1/
Documents directory.
You must update content manually before portal content is promoted to SAS
Information Delivery Portal 4.4. In this case, data explorations must be converted to reports, and directive URLs should be adjusted manually. For more information, see
“Promote the Entire Portal Application Tree” in Chapter 13 of SAS Intelligence Platform:
Web Application Administration Guide.

Administrator and the SAS Trusted User.
If web applications were deployed automatically, the script does not contain the required credentials. You must manually enter the required credentials in this script file.
Adjust Directive URLs Manually
Directive URLs are updated either during the migration of a product from one version to another version, or when a product's content is modified and updates are required.
When the script is run to adjust URLs, it updates references to metadata that has moved either during migration or an upgrade. These references are stored as SBIP
URLs.
You must update content manually before portal content is promoted to SAS
Information Delivery Portal 4.4. In this case, data explorations must be converted to reports and directive URLs should be adjusted manually. For more information, see
“Promote the Entire Portal Application Tree” in Chapter 13 of SAS Intelligence Platform:
Web Application Administration Guide.
Here are some examples of instances that require adjusting URLs manually: n
When a migration is performed, some reports might be moved to a user’s home folder. If there were references to the data in those reports (in the form of SBIP
URLs), then those references are updated by the script.
n
During a migration or an upgrade, data explorations are converted to reports. If there were references to the data explorations (in the form of SBIP URLs), then those references are updated by the script.

The instructions for running the script or batch file are provided in the
Instructions.html migration or the UpdateInstructions.html file during an upgrade. The script contains the credentials for the SAS Administrator, as well as the
SAS Trusted User. The password is always encrypted. When you have successfully loaded the content, remove the credentials for the SAS Administrator and the SAS
Trusted User.
Log Files Generated by the Scripts
When any of the scripts in the previous sections are run, log files are produced for each
SAS web application that is affected. Log messages are written to a file called
product-name_script-name_date-and-time.log For UNIX and z/OS machines, the log filename always includes the date and timestamp. For Windows machines, the log filename includes the date and timestamp for machines that use an English locale only.
These log files are located in the following directories:
On Windows:
SAS-config-dir\Lev1\Logs\Configure
On UNIX and z/OS:
SAS-config-dir/Lev1/Logs/Configure

Using the SAS Content Server
Administration Console
About the SAS Content Server Administration
Console
The SAS Content Server Administration Console enables you to manage files and
WebDAV folders in the SAS Content Server. Using the console, you can perform the following management tasks: n view folders n control access to WebDAV folders and files by setting permissions n create folders n delete folders
Access the SAS Content Server
Administration Console
To access the console, enter the following URL in your web browser and substitute the server name and port number of your SAS Content Server:
http://server:port/SASContentServer/dircontents.jsp
Note:
This console is also part of the SAS Web Administration Console. You can administer the SAS Content Server by using either interface. For more information
about accessing the SAS Web Administration Console, see “Using the SAS Web
Administration Console ” on page 86
.
Log on to the console with an unrestricted user ID (for example, sasadm@saspw). In order to use the console, you must be logged on as an unrestricted user. This provides full administrator rights to use the console.
Using the SAS Content Server Administration Console
145
As a security precaution, make sure that you log off when you are finished using the console. If you go to another URL or close the tabbed page in your browser without logging off, your console logon remains in effect. This means that the console can be accessed again without re-entering a user name and password.
A Brief Tour of the Console Interface
The following display shows an example SAS Content Server Administration Console as it appears in a browser window:
Display 10.1 SAS Content Server Administration Console
Objects in the console are either folders or files. By default, the initial view of the console displays the following folders:
sascontent
contains content that has been added to SAS Content Server by SAS applications.
You see a folder only if the folder contains content.
sasdav
contains content that has been added to the SAS Content Server. By default,
sasdav contains the following folders: n sasdav/Users contains personal repository folders for users. A user's folder is created automatically when the user logs on to a SAS web application. Users have full rights to their own folders.
n sasdav/Templates contains templates that are used for e-mail notification in
SAS solutions.
146
Chapter 10 / Administering the SAS Content Server
sasfolders
contains content that has been defined in the SAS Folders tree in the SAS Metadata
Server. You see a folder only if the folder contains content.
CAUTION! Administrators should not manage folders and content here.
The content within this folder and subfolders is mapped to SAS Folders in the SAS
Metadata Server. It is recommended that you use the SAS Management Console to add and manage folders.
Depending on the software that is installed at your site, your console might contain additional folders.
To navigate in the console, follow these steps:
1 Click an item in the list to display information about that item.
2 Use the breadcrumb trail above the list to return to a parent folder. For example, in the breadcrumb trail, click sasdav to return to the sasdav folder.
The console displays the following information for each item listed:
Item name
displays the name of the folder or file.
Primary type
is an internal value that designates the type of object in the repository.
Date created
is the date on which the object was created.
Date modified
is the date on which the object was modified.
Delete
when the delete button is clicked, the selected objects are deleted.
Permissions
when the permissions icon is clicked, opens a page where permissions can be modified for the object.
Using the SAS Content Server Administration Console
147
Modify Permissions for WebDAV Folders and
Files
The sasfolders directory should be accessed only by trusted or unrestricted users.
These users are recognized as unrestricted administrators for the SAS Content Server, and do not require the Access Control List (ACL) to grant them access to this directory.
If other types of users attempt to access this location, their permissions are verified before they are granted any access.
The sasdav directory can be accessed by regular users, and ACLs can be used to grant access to specific users and groups.
Principals can be granted permissions for folders and files. In the SAS Content Server, a principal is either a user or a group of users defined in the SAS Metadata Server.
Principals can be given permissions that allow them to perform specific tasks such as reading an object, writing to an object, deleting an object, and so on.
You set permissions for an object by specifying which principals have which types of access. To modify permissions for an object, follow these steps:
1
Click the permission icon next to the item that you want to modify. A permissions page appears.
2
For each principal listed, modify the permissions by changing each permission to
Yes or No.
Note:
You might see a principal named jcr:authenticated. This principal refers to any user who can log on to a SAS web application. By default, authenticated users have Read and Inherit Read permissions only.
3
To add more principals to the page, do one of the following: n
If you know the principal's name, enter it in the field and click Save changes.
n
Click Search for Principals to search for a name. When you find the principal that you want to add, select the check box next to the principal's name and then click Return.
148
Chapter 10 / Administering the SAS Content Server
After the principal's name appears on the permission page, you can set permissions for the principal.
The following display shows a portion of the console with permissions for a folder:

150
Chapter 10 / Administering the SAS Content Server
Note:
Although you can add a folder to the sasfolders location, the folder that you add is not added to the SAS Metadata Server. The best practice is to add folders to metadata using SAS Management Console.
Add Files to the SAS Content Server
You cannot use the SAS Content Server Administration Console to add files to folders.
To add files, you can use one of the following methods: n
Use Microsoft web folders to add content to the appropriate folder. You must use a browser on a Windows client machine in order to use this method.
For example, the sasdemo user might open the following location as a web folder:
http://myServer/SASContentServer/repository/default/sasdav/
Users/sasdemo/
Then, copy and paste content into the folder.
n
Use the SAS DAVTree utility to drag and drop folders or files into console folders.
To use this utility, run the following command:
SAS-config-dir\Levn\Web\Utilities\DAVTree.bat
On UNIX and z/OS, the utility command is DAVTree.sh.
For more information about using DAVTree, see “Using the DAVTree Utility to
Manage WebDAV Content ” on page 282
.
n
Use the SAS Publishing Framework to publish files to the WebDAV repository.
Portal users can publish portal content to the WebDAV repository by using the portal's publish and subscribe tools.
n
Programmatically publish content to WebDAV.
Usage of these tools and techniques is beyond the scope of this documentation (with the exception of the DAVTree utility).
Implementing Authorization for the SAS Content Server
151
Delete Folders or Files
Delete a single or multiple folders when you are sure that the folders and their contents are not required.
CAUTION! Exercise caution when deleting items from the SAS Content Server.
When deleting folders, the following rules apply: n n
Do not delete the sasdav or sasfolders directories.
If you delete an item in the sasfolders tree, then applications that rely on the content mapping between the SAS Content Server and the SAS Metadata Server might not be able to access the content. To add and delete SAS metadata objects, use SAS Management Console.
For information about the best practices to follow for managing SAS folders in SAS
Management Console, see “Working With SAS Folders” in the SAS Intelligence
Platform: System Administration Guide.
n
When you delete a folder, all objects within that folder are also deleted.
To delete a folder or file, select the check box for the folder or file from the Delete column. Click the Delete button. The item is deleted. You are not prompted to confirm the deletion. To delete multiple items, select multiple check boxes from the Delete column.
Implementing Authorization for the SAS
Content Server
Overview of SAS Content Server
Authorization
SAS users and groups are defined in a SAS Metadata Repository. The SAS Web
Administration Console enables you to specify which users or groups are authorized to
152
Chapter 10 / Administering the SAS Content Server
access specific folders in the SAS Content Server repository, and what type of access permissions they have for the folders.
Use the SAS Web Administration Console to create folders and associate access controls with the folders.
Note:
This topic does not describe authentication for the SAS Content Server. By default, SAS Content Server users are authenticated by using SAS token authentication.
Before you can associate access controls with a folder, you must complete these tasks:
1 Use the SAS Web Administration Console to create the folder on the SAS Content
Server.
2 Ensure that the appropriate user and group definitions exist on the SAS Metadata
Server for the SAS Content Server users and groups for whom you want to control access to the folder.
After you have created the WebDAV folders and have ensured that the appropriate user and group definitions are created on the SAS Metadata Server, use SAS Web
Administration Console to associate access controls with the folders.
Example Scenario: SAS Content Server
Authorization
Within your portal implementation, you might use the publish and subscribe capabilities to publish (write) and subscribe to (read) group folders on a WebDAV publication channel.
The following scenario shows the application's publish and subscribe setup for sales and executive teams that need different access to read (subscribe to) and write
(publish) information that is stored in three different directories on the SAS Content
Server. On the SAS Metadata Server, these teams are represented by two groups,
Americas Sales and Sales Executives.
This publish and subscribe scenario has a requirement for three different content areas, or group folders, on the SAS Content Server:
Implementing Authorization for the SAS Content Server
153 n
Catalog Sales: The /sasdav/Catalog Sales directory contains catalog sales information. The Americas Sales and Sales Executives groups can both read
(subscribe to) and write (publish) information.
n
Field Sales: The /sasdav/Field Sales directory contains direct sales information. The Americas Sales and Sales Executives groups can both read, but only the Sales Executives group can write information. n
Sales Execs: The /sasdav/Sales Execs directory contains executive-level sales information. Only the Sales Executives group can read and write information.
The following table summarizes this scenario's group-based folders on the SAS Content
Server, and the permissions for each group:

Manual Configuration Tasks
When Do I Need to Perform These Tasks?
Whenever there is a change that affects how applications access SAS Content Server, the connection information related to the server might need to be updated. Two common changes that require that you update the information are as follows: n changing from HTTP to HTTPS manually. (When HTTPS is configured with the SAS
Deployment Wizard, the wizard sets all the connections automatically.) n adding a proxy to the network, such as Apache HTTP Server, IBM Tivoli Access
Manager WebSEAL, or CA SiteMinder.
Reconfiguring the WebDAV Repository URL
In a SAS Enterprise Business Intelligence deployment, the following applications use an information service to retrieve the repository connection information from metadata:

Chapter 10 / Administering the SAS Content Server
For a network topology or protocol change, the SAS Content Server web application must also be updated with information about the connection point that is accessed with a web browser. For a topology change, the connection point might be a load balancer or an existing customer-supplied reverse proxy. For a protocol change, you need to perform these steps if SAS Web Server is reconfigured manually from HTTP to HTTPS.
To reconfigure the connection information in the SAS Content Server web application, edit the following files and change all instances of the connection information: n
SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\sas_webapps
\sas.svcs.scs.war\WEB-INF\web.xml
n
SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\sas_webapps
\sas.svcs.scs.war\WEB-INF\spring-config\webapp-config.xml
As an alternative, you can edit the ORIG files that are part of the installed files in
SASHome. In this case, you need to rebuild and redeploy the web application with the
SAS Deployment Wizard.

Overview of SAS BI Web Services
A web service is an interface that enables communication between distributed applications. Web services enable cross-platform integration by enabling applications that are written in various programming languages to communicate by using a standard web-based protocol, typically the Simple Object Access Protocol (SOAP) or
Representational State Transfer (REST). This functionality makes it possible for businesses to bridge the gaps between different applications and systems.
The following list identifies key changes that were introduced with SAS 9.3:
160
Chapter 11 / Administering the SAS BI Web Services
n
SAS BI Web Services is supported only in a Java application server deployment.
Previously, in SAS 9.2, there were two implementations of SAS BI Web Services: one written in Java that requires a servlet container, and another written in C# that uses the .NET framework.
n
Artifacts are not required to be generated in SAS 9.3. Only the metadata that is associated with the generated web service is published.
n
All stored processes are presented as web services without the need for any additional processing. If the metadata for a web service is not required to be published to the SAS Metadata Server, the additional step to generate the metadata is no longer required.

SAS Stored Processes: Developer's Guide
Managing Generated Web Services
You can select a set of stored processes in SAS Management Console and use the
Web Service Maker to deploy them as web services. The Web Service Maker generates a new web service that contains one operation for each stored process that you selected. For information about developing web services, see the SAS BI Web
Services: Developer's Guide. For information about using the Deploy as Web Service wizard in SAS Management Console, see the product Help.
When you generate a web service, the Web Service Maker publishes metadata about the new web service to the SAS Metadata Server. The metadata includes information such as the URL of the web service, keywords, and the stored processes are used by the web service. You can view and update some of this information by using SAS
Management Console and the Configuration Manager plug-in in. To import or export a generated web service, use the SAS Management Console folder view.

To delete a web service that was generated by the Web Service Maker, use SAS
Management Console. Navigate to Application Management Configuration
Manager
SAS Application Infrastructure
BI Web Services for Java 9.4
WebServiceMaker. Expand the node, right-click the web service, and select Delete.
Deleting a web service removes the metadata that is associated with the service. This action cannot be reversed.
Note:
You must grant permissions on the /System/Services folder to users who want to create SAS BI Web Services. You can also delete a web service directly from the /System/Services folder. Users need ReadMetadata and WriteMemberMetadata to create and delete web services. By default, a group named BI Web Services Users has these permissions. You can add users to this group to enable them to create and delete web services, or use your own groups and permission settings.
Configuring SAS BI Web Services for
Java
SAS BI Web Services for Java is initially configured during installation using the SAS
Deployment Wizard. To modify this initial configuration, use the Configuration Manager plug-in for SAS Management Console.
To modify common configuration properties that apply to XMLA, WebServiceMaker, and generated web services, go to SAS Management Console. Navigate to Application
Management
Configuration Manager SAS Application Infrastructure BI
Web Services for Java 9.4. Right-click to select Properties and click the Settings tab.
In the Application
General Configuration section, you can modify the following configuration properties:
Acceptable SYSCC List
When a web service operation is invoked, it in turn calls the appropriate SAS Stored
Process running on the server tier. SAS execution always returns the SYSCC macro variable upon completion. By default, if this completion code is not 0, a SOAP fault is generated and returned to the invoking client. Alternatively, a comma-separated list of acceptable SAS completion codes can be specified to alter this behavior. Also, a
162
Chapter 11 / Administering the SAS BI Web Services
hyphen separating two values can be used to specify a range of acceptable completion codes. In this case, the acceptable list of completion codes are treated as warnings rather than errors and do not cause a SOAP fault.
Note that SYSCC can be set directly by SAS code developers. Likewise, some SAS procedures set this value. See the appropriate SAS documentation to determine possible values that might be returned and whether these values are errors or warnings. For example, if a SAS procedure states that a SYSCC value less than 4 is a warning and you are willing to accept those values, set this property as follows:
0-4. Therefore, if the SAS stored process returns a value of 4 or less, it is considered successful as far as the web service is concerned and the client receives an appropriate response rather than a fault.
Enable dynamic prompts validation
When invoking web service operations for stored processes that have been configured with dynamic prompt data parameters, you can turn off validation to obtain better throughput if you are certain that these stored processes have been written in a robust manner to handle any possible data passed by clients. Dynamic prompt validation is enabled by default so that the middle-tier web service validates the client data against data providers to ensure that incoming data meets the specified criteria before calling the appropriate stored process on the server.
SAS Stored Process timeout
Set this property if you want to limit the amount of time that a stored process is allowed to run. If the stored process fails to execute in the specified time, it is canceled and a SOAP fault is returned to the invoking client. A value of zero indicates no time-out period.
Enable allowing anonymous execution
Specify whether you want to enable or disable anonymous execution.
To modify configuration properties that are specific to the Web Service Maker, navigate to the WebServiceMaker folder. Then, navigate to the Settings tab within the
Properties dialog box.
Base namespace
This property is the base namespace that is concatenated with the service name to create a target namespace to uniquely identify generated web services. For
Configuring SAS BI Web Services for Java
163 example, if the base namespace is set to http://tempuri.org, and a client creates a new service named test without specifying an overriding namespace for this new service, then the target namespace for the web service becomes http://
tempuri.org/test.
Attachment conformance
Specifies the attachment conformance that should be enabled for generated web services. There are two options: Message Transmission Optimization Mechanism
(MTOM) and SOAP Messages with Attachments (SwA). The default is MTOM.
Validate Request With Schema
Setting this property to True causes the incoming request to be validated against the service’s schema. The default is false because this operation can be CPU intensive.
Validate Response With Schema
Setting this property to True causes the resulting output created by the service execution to be validated against the service’s schema. The default is false because this operation can be CPU intensive.
Attachment Optimized Threshold
The default value is 2048 bytes. This attachment threshold is the number of bytes contained in the attachment that causes the data to be included as an out-of-band
XOP/Include MTOM attachment. An attachment containing fewer bytes is transferred inline as base64 encoding for optimization.
To modify configuration properties that are specific to a web service, navigate to the folder for that service. Then navigate to the Advanced tab within the Properties dialog box. Specify the name of each configuration property and its value in the Define New
Property dialog box.
The following advanced configuration properties are available:
AcceptSysccList
See “Acceptable SYSCC List” on page 161
. This property overrides its analogous common configuration property.
DynamicPromptsSupport
See “Enable dynamic prompts validation” on page 162
. This property overrides its analogous common configuration property.
164
Chapter 11 / Administering the SAS BI Web Services
MaxSTPExecTime
See “SAS Stored Process timeout” on page 162
. This property overrides its analogous common configuration property.
AnonymousExecution
Enabled by default. This property requires the SAS Anonymous Web user or
Webanon account to have been created previously.
BaseNameSpace
This property is the base namespace that is concatenated with the service name to create a target namespace to uniquely identify web services. For example, if the base namespace is set to http://tempuri.org, and a client creates a new service named test without specifying an overriding namespace for this new service, then the target namespace for this web service becomes http://tempuri.org/test.
AttachmentConformance
This property specifies the attachment conformance that should be enabled for generated web services. There are two options: Message Transmission Optimization
Mechanism (MTOM) and SOAP Messages with Attachments (SwA). The default is
MTOM.
ValidateRequestWithSchema
Setting this property to true causes the incoming request to be validated against the service’s schema. The default is false, because this operation can be CPU intensive.
ValidateResponseWithSchema
Setting this property to true causes the resulting output that is created by the service execution to be validated against the service’s schema. The default is false because this operation can be CPU intensive.
AttachmentOptimizedThreshold
The default is 2048 bytes. This attachment threshold is the number of bytes contained in the attachment that causes the data to be included as an out-of-band
XOP/Include MTOM attachment. An attachment containing fewer bytes is used as base 64 encoding for optimization.
Changes to properties do not take effect immediately. To apply these changes, perform one of the following tasks:

166
Chapter 11 / Administering the SAS BI Web Services
Overview of Security for Web Services
A default installation of SAS BI Web Services for Java is not highly secure. The default security mechanism for SAS web applications is SAS authentication. All requests and responses are sent as clear text. If users want to authenticate as a specific user, then they can send a user name and password as clear text as part of the WS-Security headers. If you use a RESTful request, send the user name and password in a base64 encoded Authorization HTTP header. Authentication is performed by authenticating client credentials at the SAS Metadata Server. Whenever user names and passwords must be sent as clear text or base64 encoded, SSL should be enabled to provide transport layer security.
If you want to use HTTPS to secure the transmission of credentials with the web services, and you also want to use the Deploy as Web Service wizard in SAS
Management Console, then you need to import the server certificate to SAS
Management Console. To import the server certificate to SAS Management Console, follow these steps:
1 Create a Java keystore on the local machine and import the server certificate of the server that you want to communicate with. For more information about how to perform this step, see
http://docs.oracle.com/javase/1.5.0/docs/tooldocs/windows/ keytool.html
.
2 Pass the keystore location and password into SAS Management Console using JVM options. The options that need to be set are: javax.net.ssl.trustStore=
"fully qualified path to keystore created with keytool from step 1" javax.net.ssl.trustStorePassword=
"trust store password"
To complete this step, add the following JavaArgs arguments to the sasmc.ini file, which is found at C:\Program Files\SASHome\SASManagementConsole\9.4:
JavaArgs_14=-Djavax.net.ssl.trustStore =
"fully qualified path to keystore created with keytool from step 1"
JavaArgs_15=-Djavax.net.ssl.trustStorePassword =
Securing SAS BI Web Services for Java
167
"trust store password"
If you are using XMLA web services or generated web services, an anonymous user can be configured. The anonymous web user is configured during SAS Deployment
Wizard configuration. Anonymous users cannot use the Web Service Maker; credentials must always be provided to use the Web Service Maker. If you are using XMLA web services, you can pass user credentials as XMLA properties in the payload.
SAS BI Web Services can also be secured by configuring web authentication. This provides a way for SAS BI Web Services to identify the calling user with basic web authentication that uses HTTP transport-layer security.
Note:
Web authentication can be used with both XMLA web services and generated web services. Web authentication cannot be used with the WebServiceMaker web service when SAS clients are used because these clients authenticate by using onetime passwords.
Securing SAS BI Web Services for Java
SAS Authentication
When SAS authentication is used, SAS Web Application Server does not perform any authentication on behalf of the application. Instead, SAS BI Web Services for Java authenticates client credentials against the SAS Metadata Server. Client credentials are obtained by one of the following ways (in this order):
1 Use credentials that are passed in the UsernameToken WS-Security SOAP header.
For RESTful invocation, use the credentials passed in the Authorization HTTP header.
2 Use credentials that are passed in the payload as properties (XMLA only).
3 Use anonymous credentials that are configured with the Webanon SAS metadata login account (XMLA and generated web services).
168
Chapter 11 / Administering the SAS BI Web Services
Typically, the WebServiceMaker service is invoked via the Deploy As Web Service wizard in SAS Management Console. Therefore, this service must be able to process
SAS one-time passwords. For this reason the WebServiceMaker service functions only in SAS authentication mode.
Web Authentication
As an alternative to SAS authentication, SAS Web Application Server can be configured to perform the authentication on behalf of the SAS BI Web Services for Java application. This is known as web authentication. Beginning with SAS 9.3, web authentication can also be used with RESTful web services.
Editing the web.xml File for Third-Party
Authentication
If you configure third-party authentication with products such as CA SiteMinder, and use the JavaScript Objects Notation (JSON) and REST web services, edit the deployment descriptor file. This file is located in the SASHOME \SASWebInfrastructurePlatform
\9.4\Configurable\wars\sas.biws\WEB-INF directory. Change the configuration section in the web.xml.orig file as follows:
<!-- comment out or remove this filter
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>
org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
-->
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<!-- specify different URL patterns
<url-pattern>/*</url-pattern>
-->
<url-pattern>/j_spring_cas_security_proxyreceptor</url-pattern>
<url-pattern>/j_sprint_cas_security_check</url-pattern>
</filter-mapping>
Securing SAS BI Web Services for Java
169
Rebuild and redeploy the SAS Web Infrastructure Platform web application with the
SAS Deployment Manager.
Transport-Layer Security
HTTP transport-layer security can be used instead of message-level security. The following security constraints should be applied to the web.xml.orig deployment descriptor. (See the previous section for the location.) Change the file by adding the security constraints as follows:
<security-constraint>
<web-resource-collection>
<web-resource-name>All-resources</web-resource-name>
<url-pattern>/services/XMLA/*</url-pattern>
<url-pattern>/services/dynamicServicePath/*</url-pattern>

Overview
Introduction to SAS Web Application Themes
SAS Web Application Themes provide a way to define a consistent look and feel across
SAS web applications. You can use themes to apply uniform visual customizations and company branding to all SAS web applications that support the theme infrastructure. A typical custom theme might include a banner with a standard corporate color scheme and company logo, a navigation bar with colors that coordinate with the banner, and new colors for borders and title bars.
Theme Components
A theme is a collection of resources that control the appearance of a SAS web application. The following figure shows the components of a theme:
Figure 12.1 Components of a Theme
Here is an explanation of each theme component:
Overview
173 theme templates are HTML fragments that render specific portions of pages in SAS web applications.
The templates contain dynamic substitution variables of the form
%VARIABLE-NAME that are replaced by application-specific values when the templates are used in SAS web applications.
cascading style sheets determine the colors, fonts, backgrounds, alignment, and spacing for page elements in SAS web applications. A cascading style sheet (CSS) is a standard mechanism for defining consistent and reusable presentation for web-based content.
theme descriptors are XML files that describe the style sheets, templates, and images that make up a theme.
images include graphics for icons, a company logo, and banner and page backgrounds. You can incorporate your own customized graphics files as part of a new theme. Images can be in any format supported in the browser, including GIF, PNG, and JPEG.
Note:
The application title that appears in the banner of the SAS web application is not part of the theme. You also cannot use themes to change the application name that appears in the title bar of the browser window.
The SAS Default Theme
The initial theme that is installed with the theme infrastructure is named Default. This theme is typically used as the basis for creating new themes, so you should understand its structure before you attempt to create a custom theme. Specifications for the Default theme are provided in SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions\specs\Default\index.html.
How Custom Themes Are Created and
Deployed
The SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions directory contains the scripts and resources needed to create a new theme:
174
Chapter 12 / Administering SAS Web Application Themes
n
The NewTheme script creates a directory structure for your new theme, and populates it with configuration files that are modified to create a new theme definition. The new theme is based on the SAS default theme that is shipped with the software.
n
The specs directory provides documentation for the general color palette and color and image guidelines that are specific to each user interface component. This document is useful when you are designing and defining your custom theme.
Developing a custom theme involves creating CSS files, image files, theme template files, and theme descriptor files. It is possible to create a new theme by authoring these files from scratch, but the task is laborious and requires a thorough understanding of web page design. The theme infrastructure provides a templating mechanism to simplify the process.
Instead of editing CSS and theme descriptor files directly, template files
(extension .vtl) are provided that contain key and value pairs that isolate the elements of the theme that you are likely to want to customize. In addition, context files
(extension .vctxt) enable you to create a centralized set of definitions for key values that you can use in place of explicit values to simplify the process of maintaining the template files. When you use the SAS Deployment Manager to rebuild the SAS Web
Application Themes, the context files are merged into the template files to create a complete set of shared and product-specific style sheets and theme descriptors. The build process also packages your new theme into a WAR file that is deployed to make the themes available in your production environment.
Once the theme archive is deployed, users can use the Preferences page in their SAS web application to apply the new theme (or any other deployed theme). You can also specify the custom theme as the default for all SAS web applications. This means that the theme is applied automatically for users who do not make a selection on the
Preferences page.
Note:
Previously, SAS Web Report Studio 3.1 used product-specific branding.
Product-specific branding is not available for SAS Web Report Studio 4.4. Use themes to create branding in SAS Web Report Studio 4.4. A few properties for branding that existed in SAS WebReport Studio 3.1 are supported in SAS Web Report Studio 4.4. For information about these properties and usage, see “Customizing Report Styles for SAS
Web Report Studio” in Chapter 6 of SAS Intelligence Platform: Web Application
Administration Guide.

To deploy multiple themes in your environment, follow steps 1 to 6 to design and create your themes. Then follow step 7 to move each theme from test to production environment.
176
Chapter 12 / Administering SAS Web Application Themes
You can deploy multiple themes in your corporate environment. Before deploying the new theme in a production environment, you should first test it in a test environment to ensure that SAS web applications function as expected with the new theme applied.
Step 1: Design the Theme
Overview
The first step in creating a custom theme is to plan the visual elements. Usually, the new theme is based on an existing design, your organization's intranet standards, another in-house written application, or a purchased application or solution. Some organizations have a standard color palette with color specifications.
Review the specifications for the Default theme at SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\specs\Default\index.html, and identify the component keys and image keys for the visual elements that you want to change in the new theme. Establish a set of colors that are compatible with your organization, and choose the images (for example, logos, banner images) you want to use in the new theme.
Generally, you can make the largest impact by updating the background colors, border colors, and text attributes for web application pages and SAS Information Delivery
Portal portlets. In addition, you might want to replace the SAS logo in the banner with our own organization's logo. If you select a different color palette, consider that you might need to adjust the colors in images to match the new palette.
The Color Palette page at SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions\specs\Default\html\colorPalette.html lists all 55 color keys of the default theme and specifies the default hexadecimal color value for each color key. It also provides links to documentation on each user interface element where the color is applied.
Options in Designing the Theme
When you create a new theme, there are three ways to define your theme: n
Use the Color Palette and replace the 55 default SAS colors with your organization's palette. The colors are applied automatically across the user interface.
Steps for Defining and Deploying a New Theme
177 n
Specify the color to be used for each interface component. You must specify the color for each context key of the user interface component. This approach takes more time, but it provides maximum flexibility and control.
n
Start with the Color Palette, and make individual changes to selected user interface components. This approach overrides how the color palette is applied in some cases.
If you choose to set colors for the context key of each user interface component, the web pages at SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions
\specs\Default\index.html provide tools and resources to assist you with this process.
Step 2: Create a Work Area for the Theme
To create a work area that contains a copy of the Default theme as a basis for your new theme, use one of the following scripts provided in the SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions directory: n n for Windows: NewTheme.bat theme-name true for UNIX and z/OS: NewTheme.sh theme-name true
To use the Color Palette option, the true parameter is required in the command.
Note:
The theme name must not contain spaces.
The following figure shows the theme-name directory, which is the root directory for theme resources. The \theme-name\MetadataTools directory contains SAS programs for managing the theme. The Velocity directory contains several subdirectories with files.
178

The following figure shows the subdirectory structure that is created under the SAS-
config-dir\Lev1\Web\Utilities\SASThemeExtensions\themes\theme-name\themes
\theme-name directory.
Steps for Defining and Deploying a New Theme
179
Figure 12.3 Subdirectories for Images, Styles, and Templates
Here is an explanation of the folders and their contents:
\theme-name\themes\theme-name\images
contains the standard collection of images for SAS web applications that use the theme infrastructure. The images are divided into the following subdirectories by category:
Common
contains images that are commonly used in SAS web applications.
Components
contains images for the collection of components (widgets) that are shared by
SAS web applications.
180
Chapter 12 / Administering SAS Web Application Themes
WRS
contains images for SAS Web Report Studio.
\theme-name\themes\theme-name\styles
contains a cascading style sheet file named custom.css that can be used to define additional style elements for the theme. This file is empty when the work area is created.
\theme-name\themes\theme-name\templates
contains theme templates, which are HTML fragments that render specific portions of pages in SAS web applications. The template files are divided into the following subdirectories by category:
Common
contains theme templates for page elements that are commonly used in SAS web applications.
Components
contains theme templates for the collection of components that are shared by
SAS web applications.
WRS
contains theme templates for elements in SAS Web Report Studio pages.
The following figure shows the subdirectories below the SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\themes\theme-name\Velocity directory.
Steps for Defining and Deploying a New Theme
181
Figure 12.4 Subdirectories within the Velocity Directory
Here is an explanation of the contents of the directories:
\theme-name\Velocity\Stylesheets\_shared\contexts\themes
contains a context file named theme-name.vctxt that defines context values for font families and standard colors that can be used in CSS templates.
\theme-name\Velocity\Stylesheets\Common\contexts\themes\theme-
name
contains CSS template files that are used to build style sheets for page elements that are commonly used in SAS web applications, including portal.theme-
name.vtl, sasStyle.theme-name.vtl, and sasScorecard.theme-name.vtl.
182
Chapter 12 / Administering SAS Web Application Themes
\theme-name\Velocity\Stylesheets\Components\contexts\themes
\theme-name
contains a CSS template file named components.theme-name.vtl that is used to build style sheets for the collection of components that are shared by SAS web applications.
\theme-name\Velocity\Stylesheets\WRS\contexts\themes\theme-name
contains a CSS template file named wrs.theme-name.vtl that is used to build style sheets for SAS Web Report Studio.
\theme-name\Velocity\ThemeDescriptors\contexts
contains a context file named theme-name.themeDescriptor.vctxt that defines context values that can be used in theme descriptor templates.
\theme-name\Velocity\ThemeDescriptors\contexts\custom\theme-name
contains theme descriptor template files for building the XML files that define the available collections of style sheets, theme templates, and images, including
ComponentsThemes.vtl, CustomThemes.vtl, SASThemes.vtl,
SolutionsThemes.vtl, and WRSThemes.vtl. The SemanticThemes.vtl file is added in the second maintenance release for SAS 9.3.
If you were to build the new theme at this point, it would be a fully functional duplicate of the Default theme.
Step 3: Make Desired Changes to the Styles,
Graphics, and Theme Templates
Changing Colors
To make style changes to specific page features, you must first identify the component key associated with that feature and then locate the CSS template file that sets the value for that key.
For example, suppose your new theme design calls for changing the color for the title text in the banner at the top of SAS web applications. The Banner specifications at the
Themes web site SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions\specs\Default\Components\html\Banner.html
Steps for Defining and Deploying a New Theme
183 show that the context key for the title text is Banner_Title_Text_Color and it displays its context value.
Each Themes web page displays the context keys and context values.
You can specify a new color explicitly, as follows:
Banner_Title_Text_Color=#e69b00
Because components.theme-name.vtl is a CSS template file, another option is to use the generic color values that are defined in the theme-name.vctxt file in the
\Velocity\Stylesheets\_shared\contexts\themes subdirectory of the work area for the new theme. For example, you might specify the following value instead of an explicit value:
Banner_Title_Text_Color=${Color53}
The corresponding color value is substituted in the resulting CSS when the new theme is built.
The general form for using a context value in a template file is ${context-value-name}.
Using context values instead of explicit values can make it easier to maintain the theme because you can change all component keys that use a given value by making one change to the context file.
Changing Graphics
Image files are located in three subdirectories located in the SAS-config-dir
\Lev1\Web\Utilities\SASThemeExtensions\specs\Default folder. These
184
Chapter 12 / Administering SAS Web Application Themes
subfolders are: Common, Components, and WRS. The properties of each image are defined in the Theme Descriptors files.
The process for customizing images is similar to that for customizing styles. For example, suppose your new theme design calls for changing the background image for the banner at the top of SAS web applications. A review of the Banner specifications at
SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions\specs
\Default\index.html shows that the image key for the banner background is
banner_background. A search for that string in the work area for the new theme shows the following IMAGE element in the ComponentsThemes.vtl file in the Velocity
\ThemeDescriptors\custom\theme-name subdirectory of the work area:
<Image name="banner_background" ... file="BannerBackground.gif"/>
You can change the image used for the banner background image in either of the following ways: n by replacing the existing BannerBackground.gif file in the themes\theme-
name\images\Components subdirectory of the work area with a revised image with the same name. Make sure that the new image has the following criteria: o
The filename of the new graphic is identical to the filename of the graphic being replaced.
o
The new graphic is in the same format as the original image (for example, .jpg or .gif).
n o
The dimensions of the new graphic and its pixels are same as the graphic being replaced.
If you need to change the size, filename, or the image format of the graphic, modify the theme descriptor. For example, if you replace the logo.gif file with a new file called myLogo.jpg that has a width of 300 pixels and height of 70 pixels, modify the ComponentsThemes.vtl file as follows:
<Image name="logo" description="My Logo" altTextKey="desktop.logo.text" appliesTo="ALL" width="300" height="70" file="myLogo.jpg"/> by changing the FILE= attribute in the IMAGE element in the
ComponentsThemes.vtl context file to point to a different image file.
Steps for Defining and Deploying a New Theme
185
Note:
You should not change the value of the NAME= attribute in the IMAGE element. SAS web applications depend on the NAME= attributes remaining constant.
Another common image change is to replace the SAS logo in the standard banner with your organization's logo. You can change the graphic used for the banner logo either by replacing the existing logo.gif file in the themes\theme-name\images
\Components subdirectory of the work area with a copy of your logo with that filename or by changing the target of the FILE= attribute for the IMAGE element in the
ComponentsThemes.vtl context file for which the NAME= attribute has the value
logo.
Note:
Beginning with the second maintenance release for SAS 9.3, the SAS Logon
Manager application uses graphics from the themes\theme-name\images
\semantic directory. If you want to change the logo on the SAS Logon Manager, or any other graphic shown on the logon page, review the graphics in the semantic directory and the IMAGE elements in the SemanticThemes.vtl file.
When customizing images, you should ensure that the replacement graphics have approximately the same dimensions as the original graphics. Otherwise, the images might disrupt the appearance of the applications in which they are used.
Changing Theme Templates
You should make changes to theme templates only in situations where you want to change the layout of a page element (for example, to change the logo's placement in the banner or to adjust the padding between rows in a menu). If you decide to alter a theme template, proceed with caution. SAS web applications rely on the template structure being consistent with the versions that are shipped with the software. Improper changes to theme templates might prevent SAS web applications from functioning properly. In particular, do not change the dynamic substitution variables in theme templates because SAS web applications expect the existing values.
Dynamic substitution variables should not be changed in theme templates because SAS web applications expect the existing values. However, if you need to change a dynamic substitution variable, here is an example where %BANNER_TITLE is the dynamic substitution variable:
<td nowrap id=”bantitle”
186
Chapter 12 / Administering SAS Web Application Themes
class="banner_title">%BANNER_TITLE</td>
Note:
When a new release of themes is installed at your site or an upgrade is performed, the existing theme template files are replaced by the new theme template files. If you have customized theme template files and want to retain them for future use, copy them to a different location before the installation or upgrade.
Additional Considerations
Another change that you might want to make when creating your new theme is to update the theme_displayName= element in the theme-
name.themeDescriptor.vctxt file in the Velocity\ThemeDescriptors
\contexts subdirectory of the work area. Provide a descriptive name for the new theme. The name is used in the selection list of available themes in the Preferences page in SAS web applications.
Step 4: Rebuild SAS Web Application Themes
To rebuild SAS Web Application Themes and register your themes in metadata, follow
the steps provided in “Rebuild Web Applications” on page 104
.
The rebuilt SAS Web Application Themes archive file ( sas.themes.ear) can be found in the SAS-config-dir\Lev1\Web\Staging directory. It should contain a new web archive (WAR) file for the new theme named sas.theme.theme-name.war.
Step 5: Deploy SAS Web Application Themes in Your Test Environment
To deploy the rebuilt SAS Web Application Themes to your web application server in a
test environment, see “Redeploying the SAS Web Applications” on page 107
.
If you chose to configure the web application server manually or deployed the SAS web applications manually, see your Instructions.html generated by the SAS
Deployment Wizard.
Steps for Defining and Deploying a New Theme
187
Step 6: Test the New Theme
After you have completed the deployment procedures, follow these steps to test the new theme:
1 Navigate to the portal in the production environment.
2 Log on and select Options Preferences. The new theme should appear as a selection on the Preferences page.
3
Select the new theme and observe the effect of the changes that you made in “Step
3: Make Desired Changes to the Styles, Graphics, and Theme Templates” on page
. To view the new theme, log off from the portal. Then log in to the portal to view the new theme that was applied.
4
Repeat the procedures outlined in “Steps for Defining and Deploying a New Theme ” on page 175
until you are satisfied with the display of the new theme.
If you test the new theme several times, log off from the portal and log on again to view the updated theme each time.
Step 7: Move the New Theme from Test to
Production Environment
To move a theme from a test to a production environment, follow these steps: n
Copy the entire contents of the SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions directory to the same directory path on the production machine.
n
Run SAS Deployment Manager, and use the Rebuild Web Applications option to
register the theme in the metadata. See “Step 4: Rebuild SAS Web Application
.
n
Deploy SAS Web Application Themes to your web application server. See “Step 5:
Deploy SAS Web Application Themes in Your Test Environment ” on page 186
.
188
Chapter 12 / Administering SAS Web Application Themes
Step 8: Assign the Default Theme
Overview
If you want your new or custom theme to be the default theme for all users who have not selected a theme for themselves in their application's Preferences, then you should set the new theme as the default.
There are two ways to modify the theme metadata: n
Use SAS Management Console. See “Assign the Default Theme from SAS
Management Console” on page 188
.
n
.
Assign the Default Theme from SAS Management Console
To assign a new theme as the default theme by using the SAS Management Console, follow these steps:
1 Deploy SAS Web Application Themes using the SAS Deployment Manager.
2 In SAS Management Console, on the Plug-ins tab, navigate to Application
Management Configuration Manager SAS Application Infrastructure and right-click to display the SAS Application Infrastructure Properties dialog box.
3
Click the Settings tab.
4
In the Default Theme field, enter the name of your theme.
5
Click OK to exit the SAS Application Infrastructure Properties window.
6
To enable the new theme to go into effect, restart the SAS Web Infrastructure
Platform application in the web application server.
Migrating Custom Themes
189
Assign the Default Theme with the UpdateDefaultTheme.sas
Program
To assign a theme as the default theme, use the UpdateDefaultTheme.sas program located in the SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions
\themes\theme-name\MetadataTools directory. After the
UpdateDefaultTheme.sas program has been run, the new theme will be in effect for users who have not selected a different theme on their Preferences page.
If SAS is not installed on the middle-tier machine, copy the UpdateDefaultTheme.sas program to the metadata server, and submit the SAS program on that machine.
Deleting a Custom Theme from the
Metadata
To delete a custom-developed theme from the deployment for the SAS Information
Delivery Portal, use the DeleteTheme.sas program located in the SAS-config-dir
\Lev1\Web\Utilities\SASThemeExtensions\themes\theme-name
\MetadataTools directory.
If SAS software is not installed on the middle-tier machine, copy the DeleteTheme.sas program to the metadata server, and submit the program on that system machine.
Migrating Custom Themes
Overview
To apply a custom theme that you developed for an earlier release, follow these steps:
1
Create a new theme structure. For information about creating a work area in which
to construct the new version of your existing theme, see “Step 2: Create a Work
Area for the Theme” on page 177
.
2
Migrate the cascading style sheets used in your theme.
190
Chapter 12 / Administering SAS Web Application Themes
3 Migrate the images used in your theme.
4 Migrate the theme templates.
5 Migrate the descriptors used in your theme.
Migrating Cascading Style Sheets
Before attempting to move any CSS files from an existing theme to the \themes
\theme-name\styles subdirectory of the work area for the new theme, you should first review the specifications for the Default theme at SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\specs\Default\index.html. For any feature for which a component key has been defined, you should update the corresponding component key values in the CSS template (.vtl) files in the
\Velocity\Stylesheets\Common\contexts\themes\theme-name, \Velocity
\Stylesheets\Components\contexts\themes\theme-name, and \Velocity
\Stylesheets\WRS\contexts\themes\theme-name subdirectories of the work area to achieve a compatible look and feel.
Custom style sheet files are required only if you need to provide theme support to features that are not covered by the CSS templates. For each style sheet file that you add, you must ensure that a corresponding STYLESHEET element is added to in the appropriate theme descriptor template (.vtl) file in the \Velocity
\ThemeDescriptors\contexts\custom\theme-name subdirectory of the work area for the new theme. The STYLESHEET element must specify the value all for its
PRODUCT= attribute.
Migrating Images
Before attempting to move any image files from an existing theme to the \themes
\theme-name\images subdirectory of the work area for the new theme, see the image specifications for the Default theme at SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\specs\Default\index.html. If the image from the existing theme replaces one of the images in the new theme, then you should ensure that the image from the existing theme is saved over the default image in the proper directory under the \themes\theme-name\images subdirectory. If the image
Migrating Custom Themes
191 from the existing theme does not replace an image in new theme, save it in the
\themes\theme-name\images\Common subdirectory.
For each image file that you update or add, you must ensure that a corresponding
IMAGE element is present in the appropriate theme descriptor template (.vtl) file in the
\Velocity\ThemeDescriptors\contexts\custom\theme-name subdirectory of the work area for the new theme.
Migrating Theme Templates
Before attempting to move any theme template files from an existing theme to the
\themes\theme-name\templates subdirectory of the work area for the new theme, you should consider carefully whether they are compatible with the SAS web applications. SAS web applications rely on the theme template structure being consistent with the versions that are shipped with the software. Theme templates must have the expected set of dynamic substitution variables in order for the applications to function properly.
Migrating Theme Descriptors
The theme descriptor template (.vtl) files in the \Velocity\ThemeDescriptors
\contexts\custom\theme-name subdirectory of the work area for the new theme should represent the structure of the migrated theme resources. Review the files to ensure the following: n
If you add cascading style sheet files to provide theme support for features that are not covered by CSS templates, ensure that you add corresponding new
STYLESHEET elements to the STYLES section.
n
For each image file that you update or add, ensure that you update or add a corresponding IMAGE element in the IMAGES sections.
n
If you migrate existing theme template files, ensure that you update or add a corresponding TEMPLATE element in the TEMPLATES sections to reflect the change.
192
Chapter 12 / Administering SAS Web Application Themes
Special Considerations for SAS Logon
Manager
Overview
Beginning with the second maintenance release for SAS 9.3, the SAS Logon Manager web application uses two different designs: "logon classic" and "logon corporate." The classic design is used with SAS web applications that use mostly HTML and JSP. The corporate design is used with SAS web applications that use mostly Adobe Flash technology.
The corporate design uses a different directory for images and a template file than the classic design. When you migrate your custom themes, review whether your custom images or template changes should also be added to the following images and themes.
Migrating the Logon Logo Image
To migrate a custom logo image for the logon page:
1
Change the context file to point to a new logo image.
a
Edit SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions
\theme-name\Velocity\ThemeDescriptors\custom\theme-name
\SemanticThemes.vtl
b
Change the following line to specify to a different image path.
<Image name="logo_png" file="semantic/logo.png" description="SAS: The Power to Know" altTextKey="image.sas.logo.txt" />
If you want to use your existing customer logo.gif, then change the entry to resemble the following example:
<Image name="logo_png" file="logo.gif" description="your-description-here" altTextKey="image.sas.logo.txt" />
TIP
You can change or remove the description attribute. It is used as a tooltip for the logo image.
Migrating Custom Themes
193
2 Add styles to your theme's SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions\theme-name\themes\theme-name\styles
\custom.css file. Adjust some of the values in the following example, depending on the dimensions of your logo image and the desired appearance.
.figure1 img {
width: your-image-widthpx;
height: your-image-heightpx;
}
.figure1 {
width: 100%;
min-width: your-image-widthpx;
max-width: your-image-widthpx;
}
.logonabout {
margin-bottom: 0em;
}
.banner .clearfix {
display: none;
}
.logonhd {
height: 5.0em;
}
.logonhd h1 {
padding-top: 1em;
}
Logon Banner Background Image
To migrate your logon banner background image:
1 Create a new image and copy it to a new location.
a Create a new PNG version of your custom image at SAS-config-dir
\Lev1\Web\Utilities\SASThemeExtensions\theme-name\themes
\theme-name\images\Components\BannerBackground.gif and name it
BannerBackground.png. You can use an application like Microsoft Paint to do this.
194
Chapter 12 / Administering SAS Web Application Themes
b The dimensions of BannerBackground.png are 781x145 pixels. The dimensions of BannerBackground.gif are 1063x479 pixels. You might need to resize your new image to match the size of BannerBackground.png. Again, you can use an application like Microsoft Paint to make the change.
c Copy BannerBackground.png to SAS-config-dir\Lev1\Web\Utilities
\SASThemeExtensions\theme-name\themes\theme-name\images
\semantic\.
2 If you want your BannerBackground.png image to repeat, then add a style override to the SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions
\theme-name\themes\theme-name\styles\custom.css file:
.banner {
background: url("../images/semantic/BannerBackground.png")
repeat-x scroll left top transparent;
}
TIP As an alternative to step 1, you can change the URL value to specify a different image, if you prefer.
Note:
The corporate design shares the .banner style with the classic design. If you include the preceding .banner style in your custom.css file, then the
BannerBackground.png appears in the corporate design—which might be undesirable. You can either create a BannerBackground.png image that works well for both the classic and corporate designs, or you can eliminate
BannerBackground.png by adding the following style to your custom.css file:
.banner {
background: none;
}
Logon Banner Background Color
This setting applies to the classic design only. If you want to change the banner background color that is to the right of the banner background image, edit SAS-
config-dir\Lev1\Web\Utilities\SASThemeExtensions\theme-name
\Velocity\Stylesheets\Common\contexts\themes\theme-name
\logon.theme-name.vtl. Change the Logon_Classic_Banner_Background_Color value.
Migrating Custom Themes
195
LogonArtTile.gif File
This file is not used in the new logon page for the classic or corporate designs. You do not need to migrate it.
LogonArtTop.gif File
To migrate your custom LogonArtTop.gif file:
1 Copy your custom LogonArtTop.gif from SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\theme-name\images\Common\ to SAS-
config-dir\Lev1\Web\Utilities\SASThemeExtensions\theme-name
\images\semantic\.
2 If you want this image to repeat down the page from top to bottom, edit the custom.css file and add a repeat-y attribute as shown in the following example:
.content {
background: url("../images/semantic/LogonArtTop.gif")
repeat-y scroll 0 5em transparent;
}
TIP As an alternative to step 1, you can change the URL value to specify a different image, if you prefer.
Note:
Similar to the .banner style, the .content style is used by both the classic and corporate designs. One setting might not look attractive on both designs. If you want to eliminate the graphic from the designs, you can set it to none
(background: none;).
Colors for the Classic Design
To customize the color for the About link that appears in the banner for the classic design:
1
Edit SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions\theme-
name\Velocity\Stylesheets\Common\contexts\themes\theme-name
\logon.theme-name.vtl.
2
Change the Logon_Classic_About_Link_Color value to a color that works well with your custom theme's Banner_UtilityBar_Background_Color value in SAS-config-
196
Chapter 12 / Administering SAS Web Application Themes
dir\Lev1\Web\Utilities\SASThemeExtensions\theme-name\Velocity
\Stylesheets\Common\contexts\themes\theme-name
\components.theme-name.vtl.
3 Change the additional About colors as needed. These are
Logon_Classic_About_Link_Focus_Color and
Logon_Classic_About_Link_Hover_Background_Color.
4 Adjust other Logon_Classic* colors in the logon.theme-name.vtl, as needed.
Colors for the Corporate Design
To customize the colors for the corporate design:
1 Edit SAS-config-dir\Lev1\Web\Utilities\SASThemeExtensions\theme-
name\Velocity\Stylesheets\Common\contexts\themes\theme-name
\logon.theme-name.vtl.
This file is used by the classic and corporate designs. The rest of the instructions apply to modifying the corporate-related design colors.
2 Change the page body color: a Change Logon_Corporate_Body_Background_Color to one in your theme’s color palette or set to white (#FFFFFF) to match the classic design.
b Set Logon_Corporate_Body_Background_Gradient_Start_Color and
Logon_Corporate_Body_Background_Gradient_End_Color to the same color as
Logon_Corporate_Body_Background_Color.
3 Change the page text color by setting Logon_Corporate_Page_Text_Color to one in your theme’s color palette or set to black (#000000) to match the classic design.
4 Change the About link colors: a Change the Logon_Corporate_About_Link_Color value to a color that works well with your custom theme's color palette.
Migrating Custom Themes
197 b Change additional About colors as needed. These are
Logon_Corporate_About_Link_Focus_Color and
Logon_Corporate_About_Link_Hover_Background_Color.
5 Adjust other Logon_Corporate* colors in the logon.theme-name.vtl, as needed.
Additional Changes for the Corporate Design
If you are migrating the corporate design, edit the SAS-config-dir\Lev1\Web
\Utilities\SASThemeExtensions\theme-name\themes\theme-name\styles
\custom.css file and add the following styles: body {
filter: none;
-ms-filter: none;
}
#page {
/*
* The following is required to override background image. It does not
* inherit the color key value.
*/
background: insert-Logon_Corporate_Body_Background_Color-value;

Introduction to SAS Flex Application
Themes
Some SAS Web applications, such as SAS BI Dashboard and SAS BI Portlets, are displayed with the Flex interface that is provided by SAS Flex Application Themes. At start-up time, Flex applications load Flex themes automatically. A theme consists of
ShockWave Flash (SWF) files that include cascading style sheets (CSS) files. The theme content is downloaded to the client and is cached by the user's web browser. As a result, subsequent uses of the web application result in quicker loading of theme content than it is at initial loading. The SAS Corporate theme is the default theme for all
Flex applications.
Themes can be created with the SAS Theme Designer for Flex. For information about custom themes for Flex applications, see SAS Theme Designer for Flex User’s Guide.

Benefits of SAS Flex Application
Themes
SAS Flex Application Themes are required for Flex applications, and they are downloaded as SWF files to the client's web browser. Flex theme content runs within the Adobe Flash player and offers the following benefits: n
SAS Flex Application Themes coexist with SAS Web Application Themes. For example, SAS Information Delivery Portal uses the default web theme, but it displays SAS BI Portlets with SAS Flex Application Themes.
n
Applications that use SAS Flex Application Themes offer more visual impact, interactivity, and responsiveness.
n
Improved visual impact and perceived depth are achieved through the use of skins.
Skins are graphics that are applied to common user interface components that change their appearance. For example, the Corporate theme provides skins with a color palette that reflects the SAS visual identity. Skins also include some stylized graphics in the user interface.

Scenarios
Overview of Middle-Tier Deployment
Scenarios
This section describes sample topologies for the middle-tier components. These sample topologies can help you design a middle-tier configuration that meets the needs of your organization with regard to performance, security, maintenance, and other factors.
As with all tiers in the SAS Intelligence Platform, deployment of the middle tier involves careful planning. When you design and plan the middle tier, you must balance performance requirements against a number of other criteria.
The topologies that are presented in the following sections range from simple to complex. Scenario 1 represents the deployment that results from using the SAS
Deployment Wizard to configure all the middle-tier software automatically and deploy the SAS web applications. Scenario 2 provides advanced features, such as greater security and efficiency, but can require more effort to implement and to maintain.
All scenarios include the SAS server tier. The server tier consists of a SAS Metadata
Server that resides on a dedicated machine. The server tier also includes additional systems that run various SAS Application Servers, including SAS Workspace Servers,
SAS Pooled Workspace Servers, SAS Stored Process Servers, and SAS OLAP
Servers.
Scenario 1: Web Applications Deployed in a
Single Web Application Server
Overview
This scenario illustrates the most basic topology. All of the SAS middle-tier components are installed on a single system. All the SAS web applications run in a single SAS Web
Application Server instance.
Sample Middle-Tier Deployment Scenarios

Topic
Security
Performance

Availability
Maintainability
Advantages Disadvantages
SAS Web Server acts as a reverse proxy and provides a layer of security.
TLS (SSL) can be enabled on the client side of SAS Web Server without affecting the work load on the SAS Web Application Server or the performance of the applications.
Adding firewalls to the network is a good next step.
SAS Web Server is automatically configured to cache static content.
The SAS Deployment Wizard can automate the configuration and deployment.
This topology is simple to maintain and is ideal for development environments where frequent changes might be required.
This topology does not support hundreds of concurrent users.
There are no advantages in this scenario, but the topology provides an upward path to clustering web application servers.
None
This topology does not support hundreds of concurrent users.
This topology has no provision for planned or unplanned down time.
None
Further Considerations for Scenario 1
As the maintainability advantages in the previous table indicates, scenario 1 is easy to implement. This middle-tier topology can be completely installed and configured by the
SAS Deployment Wizard.
Sample Middle-Tier Deployment Scenarios
207
A variation of this scenario is to use the SAS Deployment Wizard to add web application server instances on the same middle-tier machine. This is vertical clustering and can be configured automatically by the SAS Deployment Wizard.
Similar to clustering, the applications can be distributed to different managed servers.
Distributing the applications is similar to clustering in that additional web application server instances are used. It is different in that the managed server profiles are different
—single instances of the applications are distributed to web application servers rather than redundant instances. Distributing the applications enables more memory availability for the applications deployed on each managed server and also increases the number of users that can be supported. Some SAS Solutions are configured with multiple servers by the SAS Deployment Wizard automatically. However, you can choose to configure multiple managed servers by running the wizard with the custom prompting level and selecting this feature.
Scenario 2: Web Applications Deployed across a Web Application Server Cluster
Overview
The sample topology in this scenario includes a cluster of web application servers and deploys SAS Web Server on its own machine.
The following figure illustrates the sample topology. In most cases, the SAS Web
Application Server instances and applications are identically configured. Some applications, such as SAS BI Dashboard Event Generator, and some SAS solutions
208

applications cannot be clustered. Those are examples of when the server instances and applications are not identically configured.

The majority of the topology can be configured automatically with SAS software.
Because SAS Web Server is deployed on its own machine, it can be configured

Availability
Advantages
The SAS web applications and the web application server cluster are protected by firewalls.
The web application server and
SAS web applications can be configured to perform web authentication for single sign-on to the applications and other web resources in the network.
Disadvantages
None
Response time is improved because static content is cached by
SAS Web Server.
The greater computing capacity of the web application server cluster also improves performance.
None
Once the cluster is established, additional server instances can be added to support larger numbers of concurrent users.
None
Clustering provides fault isolation that is not possible with a single web application server. If a machine in the cluster fails, then only the users with active sessions on that machine are affected.
You can plan downtime for maintenance by taking some servers offline. New requests are then directed to the applications deployed on the remaining servers while maintenance is performed.
SAS Web Server remains a single point of failure. Software and hardware high-availability options exist to mitigate this disadvantage.
210
Chapter 14 / Best Practices for Configuring Your Middle Tier
Topic
Maintainability
Advantages Disadvantages
Configuration and deployment of the cluster and the applications can still be automated with the SAS
Deployment Wizard.
Some operations, such as redeploying web applications, can require more effort when more machines are used.
Understanding Clusters
In order to provide greater scalability, availability, and robustness, SAS Web Application
Server supports both vertical and horizontal clustering. With clustering, multiple server instances participate in a load-balancing scheme to handle client requests. Workload distribution is managed by the SAS Web Server. SAS Web Server is configured as a load-balancing HTTP proxy.
The server instances in a cluster can coexist on the same machine (vertical clustering), or the server instances can run on a group of middle-tier server machines (horizontal clustering). The web applications can be deployed on both vertical and horizontal clusters.
Requirement for Session Affinity
For SAS web applications to be deployed into a clustered environment, the SAS Web
Server implements session affinity. Session affinity is an association between a web application server and a client that requests an HTTP session with that server. This association is known in the industry by several terms, including session affinity, server affinity, and sticky sessions. With session affinity, once a client has been assigned to a session with a web application server, the client remains with that server for the duration of the session. By default, session affinity is enabled.
Understanding Demilitarized Zones
Many organizations use a series of firewalls to create a demilitarized zone (DMZ) between their servers and the client applications. A DMZ provides a network barrier between the servers and the clients. A DMZ provides this protection whether the clients reside within the organization's computing infrastructure (intranet) or reside outside the organization on the Internet.
In the previous figure, the outer firewall that connects to the public network is called the domain firewall. Typically, only the HTTP (80) and HTTPS (443) network ports are open
Adding a Vertical Cluster Member
211 through this firewall. Servers that reside directly behind this firewall are exposed to a wide range of clients through these limited ports, and as a result the servers are not fully secure.
An additional firewall, the protocol firewall, is configured between the non-secure machines in the DMZ and the machines in the secure middle-tier network. The protocol firewall has additional network ports open. However, the range of IP addresses that are allowed to make connections is typically restricted to the IP addresses of the servers that reside in the DMZ.
The DMZ usually contains HTTP servers, reverse proxies, and load-balancing software and hardware. Do not deploy SAS Web Application Server or any SAS servers that handle important business logic, data, or metadata in the DMZ.
If your applications are accessed by clients through the Internet, then you should include a DMZ as part of your deployment in order to safeguard critical information. For deployments on a corporate intranet, you might want to implement a DMZ as an additional layer of security.
Adding a Vertical Cluster Member
Vertical clustering is the practice of deploying multiple identically configured web application server instances on a single machine. This can assist with improving performance so long as the hardware is sufficiently powerful to run additional server instances. It can also offer some improvement for availability. In the event that one web application server instance crashes (or an application on one server instance stops), the applications remain available on the other web application server instances.
To add a vertical cluster member:
1 Stop the web application server instance and other middle-tier servers.
SAS-config-dir\Lev1\Web\Scripts\AppServer\appsrvconfig.cmd stop
2 Locate the SAS software depot on the machine and start the SAS Deployment
Wizard. When you start the SAS Deployment Wizard, specify your plan file or select the plan that you used from the list of standard plans.
212
Chapter 14 / Best Practices for Configuring Your Middle Tier
3 When offered the choice to install and configure software, select the check box for configuring software, clear the check box for installing software, and click Next.
4 When you specify the configuration directory, the wizard provides a warning that the directory contains existing files. Click Yes to confirm the warning.
5 On the Select Products to Configure page, select the check box for SAS Web
Application Server Configuration only and click Next.
6 On the Web Application Server: Managed Server Ports page, use the Cluster
Member Multiplier menu to specify the number of web application server instances to configure.
For the pages before this one, and after it, specify the same values that were entered during the initial configuration.
7 Stop the middle-tier servers again (they were started when the SAS Deployment
Wizard completed).
SAS-config-dir\Lev1\Web\Scripts\AppServer\appsrvconfig.cmd stop
8 Configure the SAS web applications and resources, such JDBC data sources and
JMS queues.
SAS-config-dir\Lev1\Web\Scripts\AppServer\appsrvconfig.cmd -a
The configuration scripting tool (appsrvconfig.cmd) starts the servers when it completes.
TIP Log on to SAS Environment Manager and add the new servers to your inventory.
Adding a Horizontal Cluster Member
Horizontal clustering is the practice of deploying SAS Web Application Server instances on multiple machines. This can assist with improving performance and provide greater availability to guard against hardware failure. In the event that one machine or web
Adding a Horizontal Cluster Member
213 application server instance crashes (or an application on one server instance stops), the applications remain available on the other machines.
The SAS Deployment Wizard is used to add an additional middle-tier node. When it runs, it performs the following tasks: n installs and configures a SAS Web Application Server instance n configures SAS Web Server to load-balance HTTP requests to the new server instance n starts the server instance
To add a horizontal cluster member:
1 On the machine that hosts the SAS Web Server, make sure the SAS Deployment
Agent is running. The agent can be started from SASHome\SASDeploymentAgent
\9.4\agent.bat start.
If the first instance of SAS Web Application Server is not installed on the same machine as SAS Web Server, then start the deployment agent on that machine too.
2 Copy the SAS software depot to the machine to use, or make sure the depot is available from a network share.
3 Start the SAS Deployment Wizard on the new machine to use. On the deployment step page, select Middle Tier Node.

Chapter 14 / Best Practices for Configuring Your Middle Tier
Note:
You can use the Cluster Member Multiplier menu on the Web Application
Server: Managed Server Ports page to combine vertical clustering with horizontal clustering.
4 On the first web application server instance that was configured with the SAS
Deployment Wizard, set the following JVM option when the SAS Deployment Wizard completes.
-Dcom.sas.server.isclustered=true
After you make this change, restart the web application server instance.
TIP Log on to SAS Environment Manager and add the new machine and servers to your inventory.
Tuning the Web Application Server
In addition to specifying Java Virtual Machine options, you can improve the performance of SAS web applications by configuring other aspects of the web application server's behavior. For example, two obvious ways to improve the performance of any web application are: n to limit the frequency with which servers check for updated JavaServer Pages and servlets n to make sure that the server can create sufficient threads to service incoming requests
SAS provides a set of JVM option settings in the Instructions.html file that is generated by the SAS Deployment Wizard. Use those settings as a starting point for your tuning.
Configuring HTTP Sessions in Environments with Proxy Configurations
215
Configuring HTTP Sessions in
Environments with Proxy Configurations
Resolve HTTP Session Requests in a Secure
Environment
SAS Web Report Studio uses absolute URL addresses that must be associated with the correct HTTP session. The SAS Logon Manager knows only the address that is stored in metadata, and the SAS Logon Manager redirects requests to that location.
If that address differs from the URL specified by the user, then the user's session is not tracked correctly. (For example, suppose the user specifies the internal address
http://shortname/application instead of the external address http://
shortname.example.com/application.)
When SAS Web Report Studio receives an HTTP request, the request is redirected to the SAS Logon Manager. The SAS Logon Manager authenticates the request, and redirects it back to SAS Web Report Studio.
An exception applies to this process if your environment has any front-end processor
(for example, Apache HTTP Server, web clustering, IBM Tivoli Access Manager
WebSEAL, or CA SiteMinder) configured. In these scenarios, or if a reverse proxy is configured with WebSEAL, the HTTP session request comes via an internal address.
For example, the request might come via http://host:port/application instead of an external address http://proxiedhost/application. This sequence of events triggers a redirection filter, which typically sends the request to a location in the metadata where the request format is expected in the form of shortname.example.com.
However, the redirection filter is not required because the proxy sends the request to the same location, and the same address is always used.
To ensure successful resolution of HTTP session requests in a secure environment
(any environment with a front-end processor), the redirection filter must be disabled for
SAS Web Report Studio. In addition, it is highly recommended that you disable this filter for all SAS applications.
216
Chapter 14 / Best Practices for Configuring Your Middle Tier
To disable the redirection filter for all SAS web applications, follow these steps:
1 In SAS Management Console, navigate to Plug-ins Application Management
Configuration Manager
SAS Application Infrastructure Properties and rightclick to display the SAS Application Infrastructure Properties dialog box.
2
Click the Advanced tab.
3
Click Add to display the Define New Property Window.
4
Enter the property name as shown, and specify the property value:
Property Name: App.RedirectionFilterDisabled
Property Value: True
5
Click OK to exit the Define New Property window.
6
Click OK to exit the SAS Application Infrastructure Properties dialog box.
7
To enable this change to go into effect, restart SAS Web Application Server.

Chapter 15 / High-Availability Features in the Middle Tier
Overview of High-Availability Features
The SAS middle tier can be configured for high availability. Some components, like SAS
Web Application Server, can be configured in a cluster automatically. Other components, like JMS Broker, require manual configuration to enable high availability.
The following sections provide information about strategies for enabling high availability for each component in the middle tier.
SAS Web Server
SAS Web Server is used as a load balancer for distributing HTTP requests to SAS Web
Application Server instances. The web server is the unique access point for customer to access all SAS web applications. It detects when an application server in the cluster is down and routes requests to other nodes. However, it does not have the capability to monitor the availability of individual web applications, or to monitor the health of an application server that is running, but might be performing poorly.
A single instance of the web server can be installed with the SAS Deployment Wizard.
Additional instances must be configured manually by copying an existing instance to the machines to use. From that point, there are several options to achieve high availability: n
Hardware strategy You can run multiple identical web server instances behind a hardware load balancer. Because the web server is stateless, the server instances can be cloned. There is no overhead for session management. There is no failover, but the next request after the failure is directed to a running web server instance.
Session stickiness to the web application server is honored by any web server instance. Multiple hardware load balancers can be used in combination with roundrobin DNS (the next strategy) if you require it.
n
Round-robin DNS strategy Multiple identical web server instances can be run on different hosts, and a special DNS name is created to resolve to multiple IP addresses. When clients resolve the name with DNS, they receive a list of IP
SAS Web Server
219 n addresses to use. Typically, the first IP address in the list is selected and some clients might use the next IP address if the connection times out. The DNS server rotates the sequence of the IP addresses that it returns with each request. Some products can be configured to drop an IP address from the list if a heartbeat stops.
Round-robin DNS has some limitations but is simple and widely used.
Operating system strategy You can use high-availability features in the operating system to achieve failover for the web server. Configure the web server identically on the main machine and on the hot standby. The two machines maintain a heartbeat between them. If the main machine fails or runs into difficultly, the operating system on the hot standby machine assumes the network address of the main machine and starts to service requests. Operating system failover support is available with Windows Server 2008 failover clusters and Red Hat failover domains.
For other operating systems, such as IBM AIX or Oracle Solaris, there are similar functions to support high availability for failover. See your vendor documentation for more information.
To install additional web server instances, you can use the Install Additional Software option for the SAS Deployment Wizard and install SAS Web Server only. After the software is installed, you can copy SAS-config-dir\Lev1\Web\WebServer from the primary machine to the additional machine. You need to modify the httpd.conf file so that the ServerName property matches the host name. You might need to set additional configuration options to match your network topology or to match features that are enabled in your deployment, such as HTTPS.
For the hardware-based strategy and the round-robin DNS strategy, perform the following tasks:
1 Update the connection information for each web application. For more information,
see “Specifying Connection Properties” on page 75
.
2 Based on the network topology or protocol change, perform the tasks that apply from
“Manual Configuration Tasks” on page 155
.
3 Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\server.xml file and specify the new connection information in the proxyName attribute for the Connector.
220
Chapter 15 / High-Availability Features in the Middle Tier
4 Update the server for SAS Environment Manager with the new connection information. Edit the following files and specify the correct host name and port: n
SAS-config-dir\Lev1\Web\SASEnvironmentManager\server-5.0.0-
EE\hq-engine\hq-server\webapps\ROOT\WEB-INF\web.xml
n
SAS-config-dir\Lev1\Web\SASEnvironmentManager\server-5.0.0-
EE\hq-engine\hq-server\webapps\ROOT\WEB-INF\spring\securityweb-context.xml
SAS Web Application Server
SAS Web Application Server Clustering
You can configure a cluster of SAS Web Application Server instances to provide high availability for the SAS web applications. SAS Web Server provides load balancing to direct requests to the web application server instances. You can use the SAS
Deployment Wizard to configure a vertical or horizontal cluster automatically.
SAS Web Server uses both cookies and URL encoding for session stickiness. As a result, requests are proxied to the same SAS Web Application Server instance where the session was established. Session replication across the cluster is not supported. If an instance becomes unavailable, subsequent requests are sent to a different server instance, but the original session and any data in the session are lost. Users do not need to log on again because the browser maintains a ticket granting ticket cookie from the CAS servlet in SAS Logon Manager.
SAS Environment Manager and the SAS web applications rely on the SAS Logon
Manager web application for authentication. In a clustered configuration, a failure of a web application server instance that hosts SAS Logon Manager causes a brief impact to users that do not already have a session. Once SAS Web Server detects that the web application server instance is unavailable, it directs subsequent requests to available instances. There is no impact for users who already have a session. Restarting a web application server instance that hosts SAS Logon Manager does not require a restart of any other web applications that rely on it for authentication.

Update the Connection to the Relational
Database
SAS Web Application Server uses the SAS Web Infrastructure Platform Data Server (or a third-party vendor database). The web application server is configured to test the database when it provides a new connection from the connection pool. The checks occur, at most, every 30 seconds. As a result, the web application server can recover from a failover or restart of the database but can experience up to 30 seconds of trouble connecting to the database before it recovers.
The following steps show how to configure SAS Web Application Server to take advantage of SAS Web Infrastructure Platform Data Server when it is configured for high availability. If you use a third-party vendor database, the steps for using a high availability JDBC driver and modifying the server.xml file are similar.
To configure SAS Web Application Server for a high-availability SAS Web Infrastructure
Platform Data Server, follow these steps:
1
Copy the hapostgresql.jar and ha-jdbc-properties.xml files from SASHome
\SASWebInfrastructureDataBaseJDBCDrivers\9.4\Driver to SAS-
config-dir\Lev1\Web\WebAppServer\SASSServern_m\lib.
2
Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASSServern_m\conf
\server.xml file. Locate the JDBC resources that use
org.postgresql.Driver and change the driverClassName attribute to
com.sas.postgres.ha.Driver. Then change the JDBC subprotocol. See the following example:
<Resource auth="Container" driverClassName="com.sas.postgres.ha.Driver"
factory="com.sas.vfabrictcsvr.atomikos.BeanFactory" maxPoolSize="100"
minPoolSize="10" name="sas/jdbc/SharedServices"
password="${pw.sas.jdbc.SharedServices}" testQuery="select 1"
type="com.atomikos.jdbc.nonxa.AtomikosNonXADataSourceBean"
uniqueResourceName="sas/jdbc/SharedServices"
222
Chapter 15 / High-Availability Features in the Middle Tier
url="jdbc:hapostgresql://primary.example.com:9432/SharedServices"
user="SharedServices"
/>
3 Edit the ha-jdbc-properties.xml file. The file includes sample configuration values.
Use the following information for reference: a Set activeServerCount to the number of data server instances. A value of zero for this property, or a missing configuration file, results in the driver running in pass-through mode to the standard driver.
b Add the following elements: activeServerHostn specifies the host name for the data server.
activeServerDBn
(optional) specifies the database name.
activeServerPortn
(optional) specifies the network port number for the data server.
If you want to monitor the high-availability JDBC driver, you can include logging information in the SAS Web Application Server logs. Edit the SASServern_m\lib
\log4j.xml file and a category that is similar to the following example:
<!-- =================== -->
<!-- HA driver logging -->
<!-- =================== -->
<category additivity="false" name="com.sas.postgres.ha">
<priority value="INFO"/>

Update the Connection to JMS Broker
If you configure JMS Broker for high availability, then you need to update the connection information in SAS Web Application Server.
JMS Broker
223
To configure SAS Web Application Server for a high-availability broker connection, edit
SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\server.xml. Locate the Resource elements that use the
org.apache.activemq.ActiveMQXAConnectionFactory class name and update the xaProperties.brokerURL attribute as follows:
<Resource auth="Container"
factory="com.sas.vfabrictcsvr.atomikos.BeanFactory" maxPoolSize="20"
name="sas/jms/TopicConnectionFactory"
type="com.atomikos.jms.AtomikosConnectionFactoryBean"
uniqueResourceName="sas/jms/TopicConnectionFactory"
xaConnectionFactoryClassName="org.apache.activemq.ActiveMQXAConnectionFactory"
xaProperties.brokerURL="failover:tcp://primary.example.com:61616,tcp://secondary.example.com:61616"
/>
JMS Broker
The broker is based on Apache ActiveMQ. The Apache documentation offers more than one strategy for enabling high availability. One method is to use the Shared File System
Master Slave configuration.
The SAS Deployment Wizard does not install or configure an additional instance of the broker. You can add an instance by archiving the component directory and extracting the archive on an additional machine.
To configure high availability for the broker:
1 In the existing Active MQ directory, edit the SAS-config-dir\Lev1\Web
\activemq\conf\activemq.xml file.
2 Change the directory that is specified in the kahaDB element. It initially references $
{activemq.data}/kahadb. Specify a directory that is shared between the machines that you want to use:
<kahaDB directory="/shared/directory/kahadb"/>
3 Archive SAS-config-dir\Lev1\Web\activemq with a utility like zip or tar and then extract the files on the additional machine. Use an identical directory structure.
224
Chapter 15 / High-Availability Features in the Middle Tier
4 Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASServern_m/conf/
server.xml file. Change all the brokerURL attributes for the resources to resemble the following example: brokerURL="failover://(tcp://primary.example.com:61616,tcp://secondary.example.com:61616)?randomize=false"
For more information about the broker implementation, see

Cache Locator
Number of Installed Cache Locators
The locator is used to tell new, connecting members like SAS Web Application Server where running members are located and provides load balancing for server use.
Whether one or two locators are installed depends on your deployment topology: n
In a single machine deployment, the SAS Deployment Wizard prompts for a cache locator port on the Web Application Server: Cache Locator Configuration and
Scheduling Services Cache Locator pages. If you specify different port numbers, then two locators are configured.
n
In a multiple machine deployment, two locators are configured. One is configured on the primary middle-tier machine and one is configured on the server-tier machine.
The SAS Deployment Wizard does not install and configure more than two locators. The two locators are peers and when one is down, the other can do all the work. The two locators provide a failover support.
Cache Locator
225
Configuration Steps for Windows
To configure an additional locator for Windows deployments, follow these steps:
1 On the primary middle-tier machine, the locator software is archived at SAS-
config-dir\Lev1\Web\Scripts\AppServer\src\Config\vfabrictcsvr
\gemfire663.zip
2 Extract the archive to the identical SAS-config-dir\Lev1\Web\gemfire directory on the additional machine.
3 Create an instance directory that is identical to the primary machine, for example
SAS-config-dir\Lev1\Web\gemfire\instances\ins_41415.
4 Copy the files from the instance directory on the primary machine to the additional machine.
5 Copy the gemfire\bin\winx86_64\wrapper.conf to the instance directory
(gemfire\instances\ins_41415).
Update the following lines in the wrapper.conf file: set.GEMFIRE_HOME=../..
set.INSTANCE_NAME=ins_41415 set.INSTANCE_PORT=41415 set.JAVA_HOME=$globalResource.jreHome
set.GEMFIRE_SERVICE_NAME=SAS [Config-Lev1] SAS Cache Locator 41415 set.GEMFIRE_LOCATORS=primary.example.com[41415],secondary.example.com[41415]
Specify a comma-separated list of all the locators in the GEMFIRE_LOCATORS property.
6 Install Windows service for SAS Cache Locator:
C:\SAS\Config\Lev1\Web\gemfire\bin\winx86_64\installservice.bat
7 Start the locator with the Windows service name SAS [Config-Lev1] SAS
Cache Locator 41415.

Chapter 15 / High-Availability Features in the Middle Tier
SAS Environment Manager
SAS Environment Manager supports a hot-standby fail over cluster. An overview of the concepts is available from
http://pubs.vmware.com/vfabricHyperic50/index.jsp?topic=/ com.vmware.vfabric.hyperic.5.0/Clustering_Hyperic_Servers_for_Failover.html
.
An operating system-level fail over cluster can be used to replace the hardware-based load balancer that is mentioned in the VMware documentation. SAS Environment
Manager can be configured to use an external database, so an operating system-level fail over cluster does not require shared storage devices.
The following list highlights some considerations for SAS deployment: n
As VMware indicates, the cluster detection and cache peer detection relies on multicast. Make sure that your router does not block multicast packets. Otherwise, the cluster fails to initialize properly. It is also common for virtualization technologies like VMware and Xen to not enable multicast by default.
n
By default, SAS Web Infrastructure Platform Data Server is used to provide the database for SAS Environment Manager. Even though the data server can be configured for high availability, you must configure a different database for SAS
Environment Manager to use.
Because SAS installs and configures SAS Environment Manager, the information provided by VMware about installation and configuration of the initial server instance and additional instances does not apply. The initial instance is installed and configured with the SAS Deployment Wizard.
To install and configure additional instances, follow these steps:
1 Use the Install Additional Software option for the SAS Deployment Wizard to install SAS Foundation and SAS Environment Manager on the remaining cluster machines. Use the same SASHome path that was used for the initial server instance.
SAS Web Infrastructure Platform Data Server
229
2 Copy the SAS-config-dir\Lev1\Web\SASEnvironmentManager files and directories from the first machine to the remaining cluster machines.
3 Edit the server and agent property files to change the host name to the appropriate value.
4 When you follow the rest of the steps from the VMWare documentation, keep in mind these two changes: n
The load balancer needs to route traffic for the HTTPS port 7443 in addition to port 7080.
n
Steps 5 and 6 in the VMWare documentation should be reversed. The servers need to be running before you configure the agents with the hq-agent script.
SAS Environment Manager makes calls to applications that are deployed in SAS Web
Application Server. High availability for those applications is enabled when you cluster
SAS Web Application Server.
SAS Web Infrastructure Platform Data
Server
About This Task
The information in this section describes how to configure the server for streaming replication. It is based on the information that is available from
http:// wiki.postgresql.org/wiki/Streaming_Replication
. The information is modified to accommodate for the SAS installation and configuration processes.
Throughout this section, the following terms are used: primary the host and SAS Web Infrastructure Platform Data Server that was installed first with the SAS Deployment Wizard.
230
Chapter 15 / High-Availability Features in the Middle Tier
secondary an additional machine and instance of the data server that is used for standby purposes.
Prerequisite
The account that is used to run SAS Web Infrastructure Platform Data Server must be configured with passwordless SSH between the primary machine and the secondary machine. If the account is not already configured for passwordless SSH, perform the following task.
To configure passwordless SSH, follow these steps:
1 Generate a private key that does not use a passphrase: ssh-keygen -t rsa -P ""
2 Install the public key in the authorized_keys file on the secondary machine: ssh-copy-id -i ~/.ssh/id_rsa.pub secondary.example.com
3 Log on to the secondary machine, generate a private key, and install the public key on the primary machine: ssh secondary.example.com ssh-keygen -t rsa -P "" ssh-copy-id -i ~/.ssh/id_rsa.pub primary.example.com
Install the Server Software on an Additional
Machine
To install an additional server instance, you can use the Install Additional Software option for the SAS Deployment Wizard and install SAS Web Infrastructure Platform
Data Server only. This installs the server software to the SASHome location. The server configuration directory and files, SAS-config-dir
\Lev1\WebInfrastructurePlatformDataServer, are copied from the primary server later.
SAS Web Infrastructure Platform Data Server
231
Configure the Primary and Secondary Server
To configure the servers:
1 Stop the existing server if it is not already stopped.
2 Make a SAS-config-dir\Lev1\WebInfrastructurePlatformDataServer
\archive directory on the primary server.
3 Edit the SAS-config-dir\Lev1\WebInfrastructurePlatformDataServer
\data\pg_hba.conf file and add rules that enable the secondary server to act as replication agent. The following example enables all database users from all machines to access the primary server for replication: host replication all all trust local replication all trust
4 Edit the SAS-config-dir\Lev1\WebInfrastructurePlatformDataServer
\data\postgresql.conf file and set the following: listen_address = "*" wal_level = hot_standby checkpoint_segments = 30 archive_mode = on archive_command = 'cp %p /opt/SAS/Config/Lev1/WebInfrastructurePlatformDataServer/archive/%f' max_wal_senders = 10 wal_keep_segments = 5000 hot_standby = on
Note:
Adjust the path in the archive_command value to match your deployment.
5 Copy the SAS-config-dir\Lev1\WebInfrastructurePlatformDataServer
\ directory, files, and subdirectories to the standby machine. Use the identical directory names.
6 On the secondary machine only, create a recovery command file that is named
SAS-config-dir\Lev1\WebInfrastructurePlatformDataServer\data
\recovery.conf. See the following example that applies to streaming replication:
# Note that recovery.conf must be in $PGDATA directory.
232
Chapter 15 / High-Availability Features in the Middle Tier
standby_mode = 'on'
# Specifies a connection string which is used for the secondary server
# to connect with the primary.
primary_conninfo = 'hostaddr=192.168.1.119 port=9432 user=dbmsowner'
# Specifies a trigger file whose presence should cause streaming
# replication to end (i.e., failover).
trigger_file = '/path_to/trigger'
# Specifies a command to load archive segments from the WAL archive. If
# wal_keep_segments is a high enough number to retain the WAL segments
# required for the secondary server, this may not be necessary. But
# a large workload can cause segments to be recycled before the secondary
# is fully synchronized, requiring you to start again from a new base backup.
restore_command = 'cp /path_to/archive/%f "%p"'
7 Start the server on the primary machine and then start the server on the secondary machine.

Usage Notes
How to perform a failover
Create the trigger file on the standby server after the primary server fails.
How to stop the primary server or the standby server
Use the webinfdsvrc.sh command.
How to restart streaming replication after failover
Repeat the configuration steps from step 5. These steps include copying the database files, some configuration steps, and starting the original primary server as the standby server. The primary server does not need to be stopped during these operations.
How to restart streaming replication after the standby fails
Restart the standby server after eliminating the cause of failure.
SAS Web Infrastructure Platform Data Server
233
How to disconnect the standby server from the primary server
Create the trigger file on the standby server while the primary server is running. The standby server starts and stops replicating changes.
How to resynchronize the standby server after isolation
Shut down the standby server as usual. Repeat the configuration steps from step 5.

Configuring the Middle Tier to Use an
Existing Customer Reverse Proxy
Some network topologies already have a web server that is used to proxy connections.
In these deployments, you can reconfigure the SAS middle tier so that it interacts with the existing web server. In these network topologies, it is simplest to keep SAS Web
Server in the deployment so that it can continue to load balance connections to a SAS
Web Application Server cluster.
To use an existing web server proxy:
1
Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\server.xml file. Change the value for the proxyName in the /Service/Connector element. Check the values for proxyPort and scheme:
<Connector acceptCount="100" bindOnInit="false" connectionTimeout="20000"
executor="tomcatThreadPool" maxHttpHeaderSize="16384"
maxKeepAliveRequests="15" port="${bio.http.port}"
protocol="org.apache.coyote.http11.Http11Protocol"
proxyName="proxy.example.com" proxyPort="443"
redirectPort="${bio.https.port}" scheme="https"
useBodyEncodingForURI="true"
/>
If you have more than one SAS Web Application Server instance, make the change for each one.
Note:
If the existing reverse proxy uses HTTPS with a site-signed certificate, import the certificate to the SASHome\SASPrivateJavaRuntimeEnvironment
\9.4\jre\lib\security\cacerts file.
2
In order to determine which URLs to proxy, review the SAS-config-dir
\Lev1\Web\WebServer\conf\sas.conf file.
Web Authentication
237
Each application that is identified in a pair of ProxyPass and ProxyPassReverse directives must be proxied.
3 Use SAS Management Console to specify an external connection for each SAS web
application. For more information, see “Specifying Connection Properties” on page
.
4 Use SAS Management Console to update the WebDAV connection information. For
more information, see “Manual Configuration Tasks” on page 155
.
5 Restart SAS Web Application Server.
Web Authentication
About Web Authentication
By default, SAS web applications use the form-based authentication that is provided by the SAS Logon Manager application. When credentials are provided to SAS Logon
Manager, the credentials are sent to the SAS Metadata Server for authentication. The metadata server then authenticates the credentials against its authentication provider.
The default provider is the host operating system.
As an alternative, you can configure the SAS web applications to authenticate on the middle tier. When users log on to a SAS web application, SAS Web Application Server handles the initial authentication for container-managed security.
Performing web authentication facilitates single sign-on. Most likely, your organization has several applications behind a common set of reverse proxy and HTTP servers. By having a common server handle authentication, users do not need to re-authenticate for access to each application.
See Also
For more information, see Chapter 11, “Authentication Mechanisms,” in SAS
Intelligence Platform: Security Administration Guide.
238
Chapter 16 / Enterprise Integration
Configuring Web Authentication
If you have server instances on multiple machines, then perform these steps on each machine. If you use vertical clustering (multiple servers on a machine), then you need to perform these steps only once on the machine. These instructions configure every instance of SAS Web Application Server on a machine. The following list identifies some considerations: n
Before you perform this procedure, make sure that you grant administrators access to SAS Environment Manager. Once web authentication is configured, internal accounts like sasadm@saspw are unlikely to exist in the authentication provider that you use for web authentication.
n
If you have users in SAS metadata that do not have a user ID on the Accounts tab, then a SAS identity will not be found after authentication to the web application server container succeeds and authorization takes place. Use SAS Management
Console to create an authentication domain named web. Add an account on the
Accounts tab for each of those users in the web authentication domain.
To configure web authentication, follow these steps:
Modify SAS Logon Manager Installation Files
1 Edit SASHome\SASWebInfrastructurePlatform\9.4\Static\wars
\sas.svcs.logon\WEB-INF\cas-servlet.xml and add the following code above the closing </beans> tag:
<bean id="principalFromRemoteAction"
class="org.jasig.cas.adaptors.trusted.web.flow.
PrincipalFromRequestRemoteUserNonInteractiveCredentialsAction"
p:centralAuthenticationService-ref="centralAuthenticationService" />
Note:
The previous bean definition must be entered on one line. It is shown on more than one line for display purposes only.
2 Edit SASHome\SASWebInfrastructurePlatform\9.4\Configurable\wars
\sas.svcs.logon\WEB-INF\deployerConfigContext.xml.orig and add the following bean definition. Add this within the /beans/
Web Authentication
239 bean[id="authenticationManager"]/ property[name="credentialsToPrincipalResolvers"]/list:
<bean class="org.jasig.cas.adaptors.trusted.authentication.principal.
PrincipalBearingCredentialsToPrincipalResolver" />
Note:
The previous bean definition must be entered on one line. It is shown on more than one line for display purposes only.
3 In the same file, add the following bean definition within the /beans/ bean[id="authenticationManager"]/ property[name="authenticationHandlers"]/list:
<bean class="org.jasig.cas.adaptors.trusted.authentication.handler.support.
PrincipalBearingCredentialsAuthenticationHandler" />
Note:
The previous bean definition must be entered on one line. It is shown on more than one line for display purposes only.
4 Edit SASHome/SASWebInfrastructurePlatform/9.4/Static/wars/
sas.svcs.logon/WEB-INF/login-webflow.xml. Locate the following block:
<action-state id="generateLoginTicket">
<evaluate
expression="generateLoginTicketAction.generate(flowRequestContext)" />
<transition on="success" to="viewLoginForm" />
</action-state>
Replace the previous block with the following:
<action-state id="generateLoginTicket">
<evaluate
expression="generateLoginTicketAction.generate(flowRequestContext)" />
<transition on="success" to="remoteAuthenticate" />
</action-state>
<action-state id="remoteAuthenticate">
<evaluate expression="principalFromRemoteAction" />
<transition on="success" to="sendTicketGrantingTicket" />
<transition on="error" to="viewLoginForm" />
</action-state>
5 Edit SASHome\SASWebInfrastructurePlatform\9.4\Configurable\wars
\sas.svcs.logon\WEB-INF\web.xml.orig and add the following code above the closing </web-app> tag:

</security-role>
Note:
Replace ROLE_USER with an attribute that you can use to distinguish users that are granted access to the web applications.
Note:
As an alternative to updating the web.xml.orig file, you can edit the deployed file, SAS-config-dir\Levn\Web\WebAppServer
\SASServer1_1\sas_webapps\sas.svcs.logon.war\WEB-INF\web.xml.
This avoids the need to rebuild and redeploy the application, but you need to make sure your changes are not overwritten if the application is redeployed at a later date.
Modify SAS Visual Analytics Transport Service Installation Files
These steps apply to deployments that distribute reports for SAS Mobile BI users. Make sure that you use BASIC for the auth-method. SAS Mobile BI supports BASIC authentication only.
6 Edit SASHome\SASVisualAnalyticsServices\6.2\Configurable\wars
\sas.bitransportservices\WEB-INF\web.xml.orig and remove the comment that encloses the security-constraint:
<!-- uncomment for BASIC Auth -->
<security-constraint>
<web-resource-collection>

<realm-name>SASrealm</realm-name>
</login-config>
<security-role>
<role-name>SASWebUser</role-name>

-->
Note:
As an alternative to updating the web.xml.orig file, you can edit the deployed file, SAS-config-dir\Levn\Web\WebAppServer
\SASServer1_1\sas_webapps\sas.bitransportservices.war\WEB-INF
\web.xml. This avoids the need to rebuild and redeploy the application, but you need to make sure your changes are not overwritten if the application is redeployed at a later date.
7 Replace the SASWebUser value in the file with an attribute that you can use to distinguish users that are granted access to the web applications. Using the same value that was used for SAS Logon Manager is common.
Rebuild and Redeploy Web Applications
8 Use the SAS Deployment Manager to rebuild the SAS web applications. Rebuild
SAS Web Infrastructure Platform.
If you modified SAS Transport Services, also rebuild Visual Analytics Services.
9 Stop SAS Web Application Server and then use the SAS Deployment Manager to redeploy the SAS Web Infrastructure Platform and Visual Analytics Services (if it was modified).
Do not start SAS Web Application Server now. Start it when this procedure is complete.

Chapter 16 / Enterprise Integration
Confirm that Users Have Accounts in SAS Metadata
10 Start SAS Management Console and access the User Manager plug-in.
11 Check that each user has an account on the Accounts tab. If any user that requires access to the web applications does not, then right-click the User Manager plug-in and select Authentication Domains. Click New and specify web as the name.
12 For each user that does not already have an account on the Accounts tab, add an account with the user ID in the web authentication domain.
(Optional) Validate the Previous Steps
13 You can validate the previous steps by using "file" validation at this point. This is possible because SAS configures a UserDatabaseRealm by default in server.xml.
Edit SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\tomcat-users.xml to be something similar to the following example:
<?xml version="1.0"?>
<tomcat-users>
<role rolename="ROLE_USER" />
<user username="sasdemo" password="Password1" roles="ROLE_USER" />

Update the Connection Information for SAS
Web Applications
When users authenticate through WebSEAL, it adds headers to the request to indicate that the user has already authenticated. When the request gets to SAS Web Application
Server, the valve intercepts the request and determines that the user was authenticated. The valve sets a principal in the request with the user name that was authenticated and the role AMTomcatAuthenticated. In order for user’s requests to be directed back through the WebSEAL server, the external connection information for each SAS web application must reference the WebSEAL server. See the following information: n

Support for CA SiteMinder
Overview
SAS 9.4 support for CA SiteMinder requires configuring a Web Agent to communicate with SAS Web Server and a custom Tomcat valve for SAS Web Application Server.
SAS provides the custom valve. Successful authentication results in a security token
(SMSESSION) being set in the user's web browser cookies. The valve is part of the
Tomcat request pipeline. It receives the security token in the request and communicates with the policy servers through an API to decode the user credentials from the security token. This works in conjunction with web authentication to integrate with existing CA
SiteMinder single sign-on environments.
Dependencies
SAS 9.4 integration with CA SiteMinder depends on two software applications from CA: n
CA SiteMinder Web Agent (any version) n
CA SiteMinder SDK r12.x
The software applications are not included with SAS software. They can be downloaded from the CA support page. (Downloading the packages requires a CA support account and license.)
The custom Tomcat valve has a run-time dependency on the SDK. For Java agents, CA provides two distinct implementations of the API. Either implementation can be used by including the API JAR file shown below in the classpath. However, the detailed
248
Chapter 16 / Enterprise Integration
instructions that follow describe how to use the Pure Java API (smagentapi.jar in the following table).
Table 16.1 API JAR Files and Dependencies
API JAR File
smjavaagentapi.jar

Notes
This JAR file requires setting the library path to the SDK and Web
Agent native libraries in the Java process that runs SAS Web
Application Server. You can share the SmHost.conf configuration file with the Web Agent.
This JAR file requires the Java
Unlimited Strength Cryptography
Extension (JCE).
Create two host configurations. Configure one for the Web Agent to use with SAS Web
Server and a separate one for the agent to use with SAS Web Application Server. The following table shows the sample values that are used in the following sections.

Configure the Java Unlimited Strength
Cryptography Extension
The CA SiteMinder Pure Java API requires that the Java environment used by SAS
Web Application Server to be updated with the Java Unlimited Strength Cryptography
Extension.
To configure the extension, follow these steps:
1
Download the Unlimited Strength JCE from Oracle. It is available from
http:// www.oracle.com/technetwork/java/javase/downloads/jce-7-download-443124.html
.
2
Extract the archive. In the jce directory, extract all four files (COPYRIGHT.html, local_policy.jar, README.txt, US_export_policy.jar) to JAVA_HOME\jre\lib
\security.
Note:
The default JRE is located in SASHome
\SASPrivateJavaRuntimeEnvironment\9.4\jre
Configure the Web Agent
Purpose
You can use this information to configure SAS Web Server with a web agent. This can be necessary if your site does not already have a web server that is configured with a web agent or the existing web agent is in a different top-level domain (company.com versus organization.com).
Note:
If your site already has a web server that is configured with a web agent, you can
skip to “SAS Web Application Contexts” on page 252
.
The Tomcat valve for CA SiteMinder relies on using SAS Web Server as a reverse proxy. The SAS Web Server can be configured with the Web Agent plug-in module for
Apache HTTP Server. The following sections describe how to perform this configuration. The Web Agent software must already be installed.
250
Chapter 16 / Enterprise Integration
Note:
SiteMinder provides a configuration utility. However, on Windows, it does not recognize SAS Web Server, so manual configuration is necessary.
Register the SAS Web Server Host
To register the machine with the CA SiteMinder policy server, follow these steps:
1 On Windows 64-bit platforms only, copy the ICE_JNIRegistry.dll from C:\Windows
\System32 to C:\Windows\SysWOW64.
2 Run the smreghost.bat command in the bin directory under the Web Agent installation to register the host with the policy servers. On UNIX, make sure you source the ca_wa_env.sh script first.
smreghost -i policyserver.example.com -u siteminder -p Pass
-hc hostname_apache -hn hostname_apache
-o -f ../config/SmHost.conf
If successful, the command generates the SmHost.conf file.
Configure SAS Web Server for the Web Agent
TIP You can try to use the CA SiteMinder Web Agent installer. If it does not detect
SAS Web Server, then follow the manual steps in this section.
To configure the server manually, follow these steps:
1
Create a WebAgent.conf file in the SAS-config-dir\Lev1\Web\WebServer
\conf directory. Make sure that it specifies the path to the SmHost.conf file that was generated earlier and that the agent name is correct. See the following example:
HostConfigFile="C:\Program Files (x86)\CA\webagent\config\SmHost.conf"
AgentConfigObject="sasagentconf"
EnableWebAgent="YES"
ServerPath="c:\SAS\Config\Lev1\Web\WebServer\conf"
LoadPlugin="C:\Program Files (x86)\CA\webagent\bin\HttpPlugin.dll"
AgentIdFile="C:\SAS\Config\Lev1\Web\WebServer\conf\AgentId.dat"
For UNIX deployments, the library for the LoadPlugin property is named libHttpPlugin.so instead of HttpPlugin.dll.
2
Edit the SAS-config-dir\Lev1\Web\WebServer\conf\httpd.conf file. Add lines that are similar to the following at the beginning of the LoadModule directives:
Support for CA SiteMinder
251
LoadModule sm_module "C:/Program Files (x86)/CA/webagent/bin/mod_sm22.dll"
SmInitFile "C:/SAS/Config/Lev1/Web/WebServer/conf/WebAgent.conf"
For UNIX deployments, the name of the library is libmod_sm22.so instead of mod_sm22.dll.
3 Add lines that are similar to the following in the Aliases section. Change the paths to match the location of the Web Agent software on your machine.
<IfModule alias_module>

Considerations for Multiple SAS Web Application Server
Instances
If you have more than one instance of SAS Web Application Server, perform the steps in the following sections for each server instance.
Configure Web Authentication
Follow the steps in the “Web Authentication”
procedure, but specify
SiteMinderAuthenticated for the role-name element in the web.xml.orig file.
Register the SAS Web Application Server Host
A host configuration object must be configured on the policy server for each host that runs SAS Web Application Server. Use a separate host configuration from the Web
254
Chapter 16 / Enterprise Integration
Agent used for SAS Web Server, even if the web server runs on the same host as SAS
Web Application Server.
To register the machine with the CA SiteMinder policy server, follow these steps:
1 Check the smreghost.bat command in the bin directory where the CA SiteMinder
SDK is installed. Check the values for the following variables:
JAVA_HOME
Make sure this identifies an installation of Java. You can use SASHOME
\SASPrivateJavaRuntimeEnvironment\9.4\jre.
SM_REGHOST_CLASSPATH
Make sure this path includes the smagentapi.jar and crypto.jar files. They are located in the CA SiteMinder SDK java or java64 directories.
2 Run the script to register the host with the policy servers. On UNIX, make sure you source the ca_wa_env.sh script first.
smreghost.bat -i policyserver.example.com -u siteminder -p Pass
-hc hostname_tc -hn hostname_tc
-o -f "C:\SAS\Config\Lev1\Web\WebAppServer\SASServer1_1\conf\SmHost.conf"
If successful, the command generates the SmHost.conf file.
Configure SAS Web Application Server for the Web Agent
To configure the server, follow these steps:
1 Create a WebAgent.conf file in the SAS-config-dir\Lev1\Web\WebAppServer
\SASServer1_1\conf directory. Make sure that it specifies the path to the
SmHost.conf file that was generated earlier and that the agent config object is correct. See the following example:
HostConfigFile="C:\SAS\Config\Lev1\Web\WebAppServer\SASServer1_1\conf\SmHost.conf"
AgentConfigObject="sasagentconf"
EnableWebAgent="YES"
2 Copy the sas.svcs.security.vfabrictcsvr.siteminder.jar file from the SASHOME
\SASWebApplicationServer\9.4\templates\sas\lib directory to SAS-

Configure the Policy Server
Configure the Realm
In the CA SiteMinder Administrative UI, configure the realm used by the Web Agent for
SAS Web Server, if you used it, and the Web Agent that is used for SAS Web
Application Server.
If you used an existing reverse proxy instead of SAS Web Server, the SiteMinder domain, realm, rule, and policy should be configured from the SiteMinder Administrative
UI. Use a resource filter that protects /SASLogon/login only. This is essential to internal web service calls between SAS web applications so that they are not blocked at the proxy by the Web Agent.
Configuring a single resource filter also keeps performance as high as possible. If you want to protect every SAS web application with CA SiteMinder, then you need to create a separate Realm and filter for each web application that is accessed with a web browser. (For example, /SASWebReportStudio, /SASAdmin, /SASPortal, and so on.).
Here are the high-level steps:
258
Chapter 16 / Enterprise Integration
n
Create a domain for the reverse proxy server.
n
Add the user directory to the domain.
n n n
Create a realm under the domain. Select the agent from the menu. Check that the resource filter is /SASLogon/login.
Create a rule with the resource specified as *. When you view the rule that you generated, the attribute value for the Effective Resource should appear as follows:
agent_name/SASLogon/login*
Create a policy and add users from the user directory that you defined in the domain. Add the rule that you defined to the policy.
Repeat the preceding high-level steps for SAS Web Application Server.
If you plan to use CA SiteMinder authentication for SAS BI Web Services, you also need to create a Realm and filter to protect /SASBIWS.
Special Considerations for Agent Configuration Parameters
The following table identifies some agent configuration parameters that are known to cause problems in a SAS deployment:
Parameter
BadUrlChars
RequiredCookies
Issue
This parameter is used by the Web Agent to reject requests that have certain characters in them. This parameter interferes with the DAV requests that are used by SAS Content Server. You can remove the parameter or modify it to allow all the characters that are used in the DAV requests.
This parameter can interfere with clients that use SiteMinder authentication to SAS web services. Set this parameter to access to web services is affected.

Support for Integrated Windows Authentication
259
Support for Integrated Windows
Authentication
Overview of Integrated Windows
Authentication in the Middle Tier
Integrated Windows Authentication (IWA) is a Microsoft technology that is used in an environment where users have Windows domain accounts. With IWA, the credentials
(user name and password) are hashed before being sent across the network. The client browser proves its knowledge of the password through a cryptographic exchange with the web application server.
The key components of IWA in the middle tier are an Active Directory Controller machine (Windows 2000 Server or higher), a Kerberos Key Distribution Center (KDC) in a Domain Controller machine, a machine with a client browser, and SAS Web
Application Server.
When IWA is used in conjunction with Kerberos, IWA enables the delegation of security credentials. Kerberos is an industry
‐standard authentication protocol that is used to verify user or host identity. The Kerberos protocol uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure network connection.
When Active Directory is installed on a Domain Controller running Windows 2000
Server (or higher), and the client browser supports the Kerberos authentication protocol,
Kerberos authentication is used. Use of the Kerberos protocol is determined by the following requirements: n
The client must have a direct connection to Active Directory.
n
Both the client and the server must have a trusted connection to a Key Distribution
Center (KDC) and be compatible with Active Directory.
n
Service Principal Names (SPNs) are required for multiple worker processes.
260
Chapter 16 / Enterprise Integration
Dependencies
Review the following list of software requirements and required information: n
An Active Directory Domain Controller that is running Windows 2000 Server or higher is needed.
n
The desktops for users must be Microsoft Windows 2000 (or higher) domain members and have a browser client that supports the SPNEGO authentication mechanism. Microsoft Internet Explorer Version 7.0 or later qualifies as the client.
n
The clock on the desktop machines, the domain controller, and the machine for SAS
Web Application Server should be synchronized to within five minutes.
n
The machine that is used for SAS Web Application Server must have the service principal name (SPN) registered with Active Directory. If you need to request this from your information technology support group, also request the following: o keytab file o the user name that the principal is mapped to n
Understand the organization of users and groups in your Active Directory deployment if you plan to use organizational unit or group information for authorizing access to the SAS web applications.
Verifying Prerequisites
Verify the Kerberos Service Principal Name
Active Directory provides support for service principal names (SPN). SPNs are a key component in Kerberos authentication. SPNs are unique identifiers for services running on servers. Every service that uses Kerberos authentication needs to have an SPN set for it so that clients can identify the service on the network. An SPN usually matches the pattern of [email protected]. You need to confirm that an SPN for the machine used with SAS Web Application Server is registered in the Kerberos realm. If an SPN is not set for a service, clients have no way of locating that service. Without correctly set
SPNs, Kerberos authentication is not possible.
Support for Integrated Windows Authentication

To verify that the SPN for the service is registered, follow these steps:
1 Verify that there is a mapping already configured: setspn -F -Q HTTP/hostname.example.com

The value for hostname-http is identified in the CN from the previous command output.
Verify the Kerberos Keytab File
A keytab is a file containing pairs of Kerberos principals and encrypted keys. The keys are derived from the Kerberos password. The keytab file contains the information for
SAS Web Application Server to authenticate to the Key Distribution Center (KDC). You can get the keytab file from your information technology support group. The file must be copied to the machine used for SAS Web Application Server. The file must be readable by the user account running SAS Web Application Server. The file should not be readable by other accounts.
262
Chapter 16 / Enterprise Integration
To verify the keytab file, follow these steps:
1 (Optional) Move the keytab file to SAS-config-dir\Lev1\Web\WebAppServer
\SASServer1_1\conf directory.
If you do not copy the keytab to the SASServer1_1\conf directory, then make sure that you substitute the path in the configuration files.
2 The command for verifying a key tab depends on the operating environment.
Windows Specifics:
ktab.exe —l —k FILE:hostname-http.keytab
KVNO Principal
-----------------------------------------------
1 HTTP/[email protected]
UNIX Specifics:
ktutil rkt path-to/hostname-http.keytab
list -e slot KVNO Principal
---- ---- ------------------------------------------------------------
1 3 HTTP/[email protected] (arcfour-hmac)
TIP The encryption type or types (arcfour-hmac) is used in the next section for configuring SAS Web Application Server.
For more information about the ktab.exe or ktutil commands, see the vendor documentation.
Configuring SAS Web Application Server
The information in this section is modified from
http://tomcat.apache.org/tomcat-7.0doc/windows-auth-howto.html
.
If the machine already has a Kerberos configuration file, such as either C:\windows
\krb5.ini or /etc/krb5.conf, you can use the existing file. In this case, specify
Support for Integrated Windows Authentication
263 the -Djava.security.krb5.conf= JVM option to specify the path. Substitute the path in the examples.
To configure SAS Web Application Server, follow these steps:
1 If you do not have an existing configuration file, you can create a SAS-config-dir
\Lev1\Web\WebAppServer\SASServer1_1\conf\krb5.ini file with contents that are similar to the following example:
[libdefaults] default_realm = EXAMPLE.COM
default_keytab_name = FILE:C:\SAS\Config\Lev1\Web\WebAppServer\SASServer1_1\conf\
hostname-http.keytab
default_tkt_enctypes = arcfour-hmac default_tgs_enctypes = arcfour-hmac forwardable=true
[realms]
EXAMPLE.COM = {
kdc = adsvr.example.com
}
[domain_realm]
EXAMPLE.COM= EXAMPLE.COM
example.com= EXAMPLE.COM
Note:
The encoding types in the example are based on the ktutil command output from the previous section. If AES256 encryption ciphers are included in the ktutil output, be aware that they require using the Java Unlimited Strength
Cryptography Extension.
2 Verify that Kerberos authentication succeeds. Use the kinit command that is provided in the SASHOME\SASPrivateJavaRuntimeEnvironment\9.4\jre
\bin directory.
kinit -k —t c:\path-to\hostname-http.keytab
HTTP/hostname.example.com
Be sure the results are similar to the following:
New ticket is stored in cache file C:\path
3 Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\jass.conf file. Add the following to the end of the file: com.sun.security.jgss.krb5.initiate {
264
Chapter 16 / Enterprise Integration
com.sun.security.auth.module.Krb5LoginModule required
doNotPrompt=true
principal="HTTP/[email protected]"
useKeyTab=true
keyTab="C:/SAS/Config/Lev1/Web/WebAppServer/SASServer1_1/conf/ hostname-http.keytab"
storeKey=true;
}; com.sun.security.jgss.krb5.accept {
com.sun.security.auth.module.Krb5LoginModule required
doNotPrompt=true
principal="HTTP/[email protected]"
useKeyTab=true
keyTab="C:/SAS/Config/Lev1/Web/WebAppServer/SASServer1_1/conf/ hostname-http.keytab"
storeKey=true;
};
4 Edit the SAS-config-dir\Lev1\Web\WebAppServer\SASServer1_1\conf
\server.xml file. Configure a Realm to establish roles for authenticated users.
The following example uses a JNDIRealm to retrieve a user's roles from the Active
Directory LDAP:
<Realm className="org.apache.catalina.realm.JNDIRealm"
connectionURL="ldap://adsvr.example.com:389"
connectionName="CN=oneUser,OU=User Accounts,DC=example,DC=com"
connectionPassword="********"
userBase="OU=User Accounts,DC=example,DC=com"
userSearch="sAMAccountName={0}"
commonRole="ROLE_USER"
/>
Lnow the role name that is returned from Active Directory. The name is either a role name that is associated with the user such as ROLE_USER.
Note:
For deployments that include SAS Mobile BI you need to modify the realm so that it can also be used for BASIC authentication.
5 Either of the previous realm definitions uses the keytab file to connect to the Active
Directory LDAP. In order for the connection to succeed, SAS Web Application
Server must be started with the following JVM options:
-Djava.security.krb5.realm=EXAMPLE.COM
-Djava.security.krb5.kdc=example.com
-Djava.security.krb5.conf=/path-to/krb5.ini
Support for Integrated Windows Authentication
265
-Djavax.security.auth.useSubjectCredsOnly=false

Follow the steps in the “Web Authentication” on page 237
procedure, but specify
SPNEGO as the method in the web.xml.orig file for SAS Logon Manager. The changes are similar to the following example:
<security-constraint>
<web-resource-collection>
<web-resource-name>All resources</web-resource-name>
<url-pattern>/login</url-pattern>
</web-resource-collection>
<auth-constraint>

Using the SAS Anonymous Web User with SAS Authentication
The SAS Anonymous Web User (webanon) is an optional account that can be used to grant web clients anonymous access to certain SAS Web Infrastructure Platform applications (SAS BI Web Services and SAS Stored Process Web Application). This anonymous account is configured with the SAS Deployment Wizard and is applicable only when SAS authentication is being used. If web authentication is used, the web application server processes authentication requests, and this anonymous account has no effect.
270
Chapter 17 / Middle-Tier Security
If the webanon account is configured, it is used when a web service is configured for
SAS authentication, and credentials are not supplied. If the webanon account is not configured, there are no credentials for authentication, and the request fails.
In a default deployment, this anonymous account is configured as an internal user account. To determine whether to enable the webanon user account, administrators must decide whether they want to require clients to provide credentials for all requests.
When clients provide credentials to an incoming request, these credentials are always used for authentication whether the account has been enabled or not.
The webanon user is defined in the following locations: n in metadata. In default deployments, the SAS Anonymous Web Service User is an internal user account that is known only to SAS and that is authenticated internally in metadata. When internal authentication is used, it is not necessary for this user to have a local or network account.
n in the operating system of the metadata server machine, only if you selected the
External authentication option for this user during a custom installation.
Configuring SAS Web Server Manually for HTTPS
Use of TLS with SAS Web Applications
Transport Layer Security is a successor protocol to SSL. It is used to provide network security and privacy. In addition to providing encryption services, TLS uses trusted certificates to perform client and server authentication, and it uses message authentication codes to ensure data integrity.
This documentation assumes that you have a basic understanding of TLS and SSL and that you know how to obtain and use trusted certificates.
The best practice is to acquire CA-signed certificates before you install and configure
SAS software. You can specify the location of the certificate to the SAS Deployment
Configuring SAS Web Server Manually for HTTPS
271
Wizard and it can configure SAS Web Server to use it. For more information, see “Using
.
Reconfiguring to Use HTTPS
If you did not choose to configure with secure sockets during the initial installation and configuration with the SAS Deployment Wizard, you can SAS Web Server to use
HTTPS. Follow these steps:
1 Create a private key, generate a certificate signing request, and get a signed certificate. For more information, see Encryption in SAS.
2 Stop SAS Web Server and all SAS Web Application Server instances.
3 If the directory SAS-config-dir\Lev1\Web\WebServer\ssl does not exist, then create it.
Put the certificate file and key file in this directory.
4 Edit SAS-config-dir\Lev1\Web\WebServer\conf\httpd.conf and remove the # from the following line:
#Include C:/SAS/Config/Lev1/Web/WebServer/conf/extra/httpd-ssl.conf
5 Edit SAS-config-dir\Lev1\Web\WebServer\conf\extra\httpd-ssl.conf and make the following changes: a Locate the following line and make sure it refers to the HTTPS port that you want the server to listen on:
Listen 443 https
Note:
Be aware that on UNIX platforms, you must start SAS Web Server as root in order to listen on ports below 1024.
b Locate the following line and make sure it refers to the same HTTPS port:
<VirtualHost _default_:443> c Locate the following lines for the certificate file and key file and enter the correct filenames:
272
Chapter 17 / Middle-Tier Security
SSLCertificateFile "ssl/myhost.crt"
SSLCertificateKeyFile "ssl/myhost.key"
6 For each instance of SAS Web Application Server, edit SAS-config-dir
\Lev1\Web\WebAppServer\SASServern_m\conf\server.xml and make the following changes to the Connector element: n n
Change the proxyPort attribute to specify the HTTPS listen port.
Change the scheme to https.
7 Use SAS Management Console to update the protocol and port number for each
web application. For more information, see “Specifying Connection Properties” on page 75
.
8 Use SAS Management Console to update the SAS Content Server connection
information. For more information, see “Manual Configuration Tasks” on page 155
.
9 If the certificate that you use is not signed by a certificate authority (CA) that would be located in the JRE default trust store (for example, VeriSign), then add all the CA certificates in the chain to the SAS Private JRE trust store (the cacerts file). Do this for all middle tier machines before starting any servers.
You also need to import the certificate chain for server-tier machines to support any
Java clients such as PROC SOAP. Also do this for client tier products.
10 Configure the server tier and client tier.
UNIX Specifics:
For the server tier, you can create a PEM file that contains all trust certificates in the chain and use the file in the SSLCALISTLOC= SAS system option or use the SSL_CERT_DIR environment variable. For more information, see SAS
Intelligence Platform: Installation and Configuration Guide.
Windows Specifics:
For server and client tiers machines, add any required CA certificates to the Windows trust store.
11 Start SAS Web Server and then start each SAS Web Application Server instance.

SAS Intelligence Platform: Installation and Configuration Guide
Configuring SAS Web Application Server to Use HTTPS
In deployments that use SAS Web Server, the SAS Deployment Wizard does not include an option to configure SAS Web Application Server for HTTPS. The communication path between SAS Web Server and SAS Web Application Server uses
HTTP.
In order to use HTTPS between SAS Web Server and SAS Web Application Server, follow these steps:
1
Create a private key, generate a certificate signing request, and get a signed certificate. For more information, see Encryption in SAS.
274
Chapter 17 / Middle-Tier Security
2 If the certificate that you use is not signed by a certificate authority (CA) that would be located in the JRE default trust store (for example, VeriSign), then add all the CA certificates in the chain to a JKS format keystore.
openssl pkcs12 -export -chain -inkey myhost.key -in myhost.cer -name "web app server" -CAfile chain.pem -out myhost.p12
keytool -importkeystore -deststorepass storepass -destkeypass keypass -destkeystore myhost.jks -srckeystore myhost.p12 -srcstoretype PKCS12 -srcstorepass passwd -alias myhost
For information about the openssl and keytool commands, see the vendor documentation.
3 Edit SAS-config-dir\Lev1\Web\WebAppServer\SASServern_m\conf
\server.xml. Duplicate the existing Connector element and add the following attributes: n
secure="true"
n
SSLEnabled="true"
n
keystoreFile="/path-to-/myhost.jks"
n
keystorePass="storepass"
Note:
Once you have completed your changes and confirmed that SAS Web
Application Server is using HTTPS, edit the server.xml file again and remove the
Connector element that was left using HTTP.
4 For SAS WebApplication Server, set the following JVM options:
-Dsas.scs.port=8443 -Dsas.scs.scheme=https -Dsas.auto.publish.port=8443
-Dsas.auto.publish.protocol=https
5 For SAS Web Server, make the following changes: a Edit SAS-config-dir\Lev1\Web\WebServer\conf\sas.conf and change the BalancerMember directives to use https as the protocol and the HTTPS port that SAS Web Application Server is listening on. See the following example:
BalancerMember https://myhost.example.com:8443
route=myhost.example.com_SASServer1_1
b Edit SAS-config-dir\Lev1\Web\WebServer\conf\extra\httpd-

FIPS 140-2 Compliance
About FIPS Compliance in the SAS Middle-
Tier
The following sections describe how to configure components in the middle tier to use cryptographic modules that are FIPS 140-2 compliant. Completing these procedures do not result in middle tier components that are FIPS-140 compliant, only that the components are using a FIPS-140 compliant cryptographic module.
More information about the Federal Information Processing Standard 140-2 can be found at
http://csrc.nist.gov/publications/fips/fips140-2/fips1402.pdf
.
Before You Begin
One of the tasks in this section is to configure SAS Web Application Server to use the following native libraries: n
APR library n
JNI wrappers for APR used by Tomcat (tc native) n
OpenSSL libraries
The binaries for these native libraries that are shipped with SAS 9.4 have a known problem that prevents them from being used. Contact SAS Technical Support for assistance with getting the native libraries for your platform.
276
Chapter 17 / Middle-Tier Security
Configuring SAS Web Server
SAS Web Server must be configured to use HTTPS. This is performed most easily during initial configuration with the SAS Deployment Wizard. Selecting the option to use
HTTPS with SAS Web Server causes the server to use OpenSSL though the mod_ssl module for Apache HTTP Server. OpenSSL has a FIPS module that is certified as FIPS
140-2 compliant. As a result, the server can initialize the OpenSSL software in FIPS mode with a change to the server’s configuration file.
Edit the SAS-config-dir\Levn\Web\WebServer\conf\extra\httpd-
ssl.conf file and add the following statement before the VirtualHost directive:
SSLFIPS on
Restart the server and verify from the log\server.log file that the server successfully initialized in FIPS mode. In this mode, the server only establishes connections with clients that use the TLSv1 protocol and strong encryption.
Configuring SAS Web Application Server
The Apache Portable Runtime (APR) is a native web server library that can be used by
SAS Web Application Server to leverage native library support for OpenSSL. Using a native library typically results in better performance than approaches that use Java.
SAS Web Application Server can be started in FIPS mode by setting FIPSMode="on" on the APR listener. This option is new to Tomcat 7 (that is part of SAS Web Application
Server). Three native components are required:
To modify an existing SAS Web Application Server instance to use the APR, follow these steps:
1
Perform the steps in “Configuring SAS Web Application Server to Use HTTPS”
.
However, look at Connector settings in Step 4b
. You can make the changes all at once.
2 Locate the libraries that you received from SAS Technical Support.
3 Edit the script files for SAS Web Application Server to use the libraries.

For UNIX deployments, edit SASServer1_1/bin/tcruntime-ctl.sh to include lines similar to the following example:
Example Code 17.2 Changes to tcruntime-ctl.sh for UNIX
LD_LIBRARY_PATH="/path_to/lib" export LD_LIBRARY_PATH
4 Edit SASServer1_1\conf\server.xml and make the following changes: a Add the following listener to the Server element:
<Listener
SSLEngine="on"
className="org.apache.catalina.core.AprLifecycleListener"
FIPSMode="on" /> b Change the Connector to use Http11AprProtocol and specify the other SSL parameters. Here is an example:
<Connector acceptCount="100" connectionTimeout="20000"
executor="tomcatThreadPool" maxKeepAliveRequests="15"
port="8443" scheme="https" secure="true"
protocol="org.apache.coyote.http11.Http11AprProtocol"
proxyName="hostname.example.com" proxyPort="8443"
redirectPort="8443" useBodyEncodingForURI="true"
SSLCertificateFile="${catalina.base}/ssl/hostname.crt"
SSLCertificateKeyFile="${catalina.base}/ssl/hostname.key"
SSLCertificateChainFile="${catalina.base}/ssl/chain.pem"

About the DAVTree Utility
The DAVTree utility is a stand-alone Java application that provides a tree view of
WebDAV resources. The utility enables you to manipulate content by copying files to a
WebDAV repository or by creating text files such as forms and templates.
The utility presents information in a tree view. When you select a resource item in the tree on the left side of the window, the WebDAV properties for the resource are displayed on the right side.
Here is an example DAVTree interface:
In the interface, you see only the content that you are authorized to see.
Start the Utility and Connect to a WebDAV
Location
To use this utility, follow these steps:

Using the Package Cleanup Utility to
Remove Packages
Overview of the Package Cleanup Utility
The Package Cleanup utility provides a simple, command-line interface for deleting or listing packages that have been published in a publication channel or in a WebDAV repository.
The SAS Publishing Framework supports channels that you define in the SAS Metadata
Repository. Once channels have been defined, users can publish packages to the channels. For example, portal users can subscribe to available channels, view the persisted packages, and publish content (files, links, stored processes, and information maps).
Channels can be defined with archive or WebDAV persistent stores. When a package is published to a channel that is defined with a persistent store, the package is first persisted to that location and then it is published to all subscribers of that channel. All persisted packages have an expiration date. However, expired packages are not deleted automatically; you must explicitly delete them. You can use the Package
Cleanup utility for this purpose.
Here is the path to the utility:
On Windows:
SAS-config-dir\Levn\Web\Utilities\PackageCleanup.bat
On UNIX and z/OS:
SAS-config-dir/Levn/Web/Utilities/PackageCleanup.sh.
The Package Cleanup utility enables you to review basic information about a persisted package and delete both the metadata and the actual package. Deletions are based on the expiration date of the package. This utility supports the deletion of packages from
Using the Package Cleanup Utility to Remove Packages
287 either type of persistent store (archive or WebDAV). The utility also supports the deletion of packages that are not defined in any channel.
The Package Cleanup utility also supports a listing feature. The utility can be used to display information about packages that are published in a particular channel, packages that are not defined in any channel, and packages that exist on a WebDAV server.
Note:
You must have the appropriate permissions on a channel in order to delete packages from the channel. See the “Authorization Model” chapter in the SAS
Intelligence Platform: Security Administration Guide.
Deleting Packages
Delete Packages
To delete packages, follow these steps:
1 Run the command and specify the deletion date. You can also provide one of the following arguments: n a channel name in order to delete packages that are defined in a specific channel n a WebDAV URL in order to delete packages that are in the specified WebDAV location
Note:
If you do not provide the channel or WebDAV URL, then the utility deletes only orphaned packages that are not defined for any channel or WebDAV URL.
After you run the command, the utility displays a list of packages that match your deletion criteria and prompts you to confirm deletion.
2 Respond to the prompt to confirm deletion of the packages or to exit without deleting any packages.
Minimal Syntax for Deleting Packages
Here is the minimal syntax for deleting packages that are defined in a channel:
PackageCleanup
-d expiration-date
-ch channel-name
288
Chapter 18 / Using the SAS Web Infrastructure Platform Utilities
-metauser Metadata-Server-username
-metapass Metadata-Server-password
-domain authentication-domain
The utility deletes all packages in the specified channel that expire before the date and time specified.
Here is the minimal syntax for deleting packages that are not defined in a channel:
PackageCleanup
-d expiration-date
-metauser Metadata-Server-username
-metapass Metadata-Server-password
-domain authentication-domain
Here is the minimal syntax for deleting packages that are defined in a WebDAV server:
PackageCleanup
-url WebDAV-URL
-username WebDAV-Server-username
-password WebDAV-Server-password
-d expiration-date
-metauser Metadata-Server-username
-metapass Metadata-Server-password
-domain authentication-domain
Delete Specific Packages
To delete a specific package, specify -package package-name (or -pkg package-
name) along with the date. The PACKAGE option enables you to specify the name of the package to delete.
Change Prompt Behavior
When you run the utility command, the utility displays a list of packages that match your deletion criteria and prompts you to confirm deletion of all the packages that are listed.
You can override this default behavior in order to be prompted for each package individually.
To override the default, specify -prompteach. You are then prompted to delete each package that meets the deletion criteria. After each package is processed, the utility displays a final list of all packages that were selected. You can then choose to delete all of those packages or exit without deleting any packages.
Using the Package Cleanup Utility to Remove Packages
289
You can also turn off prompting altogether by specifying -noprompt. When you run the utility in batch mode, you must use the -noprompt option (unless shell programming is provided to respond to the prompts). It is best to run with prompts when you are learning how to use the application. With prompts, you can review proper date formatting and correct package deletion candidates with the option to exit without deleting any packages.
List Packages
To obtain a list of packages, run the command and specify the -list option. You can also provide one of the following arguments: n a channel name in order to list packages that are defined in a specific channel n a WebDAV URL in order to list packages that are in the specified WebDAV location
Note:
If you do not provide the channel or WebDAV URL, then the utility displays only orphaned packages that are not defined for any channel or WebDAV URL.
The LIST option lists the following information for each package: n package name n date and time that the package was created n date and time that the package expires
Here is the minimal syntax for listing packages that are defined in a channel:

Using JMX Tools to Manage SAS
Resources
About JMX and MBeans
SAS servers implement common administrative interfaces. These interfaces enable you to perform basic administrative functions such as stopping, pausing, and resuming servers. You can also use the interfaces to monitor the health of the servers via realtime and historical metrics. Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, system objects, devices
(such as printers), and service-oriented networks. JMX managed beans, known as
MBeans, have been implemented to provide a standard way of managing SAS resources.
Accessing the SAS MBeans
About Accessing the SAS MBeans
You can use any of the standard JMX monitoring tools to access the MBeans that manage SAS resources. To use these tools, you must do the following:
1
Enable access to the MBeans from the web application server. See “Configure the
Web Application Server to Enable JMX Client Access” on page 294
.
294
Chapter 18 / Using the SAS Web Infrastructure Platform Utilities
2 Use an application to connect and access the SAS MBeans. Follow the specific instructions for your JMX tool. For information about using the JConsole tool, see
“Manage SAS Resources Using JConsole” on page 294
.
Configure the Web Application Server to Enable JMX Client
Access
You configure the web application server to enable access to the MBeans by setting specific Java system options.
Specify the following Java Virtual Machine (JVM) argument to access the MBeans locally: com.sun.management.jmxremote
Specify the following JVM argument to access the MBeans from a remote system.
Replace portNum with the port number to use for JMX RMI connections: com.sun.management.jmxremote.port=portNum
Remote monitoring and management requires security to ensure that unauthorized persons cannot control or monitor your application. It is recommended that you set the following JVM arguments when MBeans are accessed remotely: com.sun.management.jmxremote.authenticate=true | false com.sun.management.jmxremote.ssl=true | false
For information about these arguments, see the Java documentation.
Manage SAS Resources Using JConsole
JConsole is a JMX tool that is included with the standard Java Development Kit (JDK).
The information provided through JMX technology enables JConsole to provide information about application performance and functions. You can use JConsole to interact with the JMX MBeans that are available to manage SAS resources. The console's simple user interface displays all MBeans in a tree navigator on the left side of the window. When you select a specific MBean, its attributes, operations, notifications, and other information are displayed on the right side of the window.
To access information about SAS resources using JConsole, follow these steps:
1 Start JConsole by running the following command:
Using JMX Tools to Manage SAS Resources
295
JDK-HOME\bin\jconsole
2 Connect to the MBean server as follows: n
If you are accessing the MBeans locally, the Local tab should display every JVM that is running on the local system that was started with the same user ID as
JConsole. Select the appropriate JVM and click Connect.
n
If you are accessing the MBeans remotely, follow these steps:
1 Select the Remote tab.
2 Enter the host on which the JVM is running, along with the port where the
RMI connector was registered.
3 You might need to specify credentials if authentication to the MBean server is required.
4 Click Connect to connect to the MBean server.
3 Select the MBeans tab. This tab displays a tree view of all the registered MBeans.
4 Expand the com.sas.services domain to see all MBeans registered in this domain.
5 Select the ServerFactory MBean.
6 In the right pane, select the Operations tab. You can now see the operations
(listing, stopping, pausing, and so on) so that you can list the defined SAS servers and manage your running SAS servers. When you invoke one of the manage-server operations, a new MBean is registered. The MBean is connected to the specified, running SAS server. The newly registered MBean can then be used to manage and monitor that particular SAS server.
Understanding How to Use the SAS MBeans
About the SAS MBeans
There are three primary MBeans provided by the SAS Web Infrastructure Platform for managing and monitoring SAS resources:
296
Chapter 18 / Using the SAS Web Infrastructure Platform Utilities
n
ServerFactory MBean n
Spawner MBean n
Server MBean
The following sections describe these MBeans.
ServerFactory MBean
The ServerFactory MBean is the starting point for managing SAS servers. This MBean is registered during deployment of the SAS Web Infrastructure Platform and is named as follows: com.sas.services:type=ServerFactory
During initialization, the ServerFactory MBean connects to the SAS Metadata Server.
This enables the MBean to list all SAS servers defined in the metadata. The MBean can then be used to register additional MBeans that enable the running servers to be managed and monitored directly. The ServerFactory MBean does not have any attributes, but supports three operations: listDefinedServers() provides a list of SAS IOM servers that are defined in the Metadata Server.
Information that is returned for each defined server includes the server name, host, port, and server type. To begin actively managing a server, specify the name of the server on the manageServerByName operation.
manageServerByName(String ServerName, String Host) registers a Server MBean that enables you to actively manage the specified IOM server. The newly registered MBean connects to the running IOM server and can then be used to manage and monitor that server. The host name can be left blank if the IOM server is defined to run on only one host. If defined to run on multiple hosts, the proper host name should be provided.
The manageServerByName() operation does not work on a server that is spawned by the SAS Object Spawner.
manageServer(String Host, Integer Port, String Username, String Password) registers a Server MBean that enables you to actively manage the specified IOM server. The IOM server that is managed is identified by the host and port provided
Using JMX Tools to Manage SAS Resources
297 on the manageServer operation. The newly registered MBean can be used to manage and monitor that specific IOM server. This operation is useful when the IOM server is not defined in the Metadata Server.
Spawner MBean
The Spawner MBean is created whenever an IOM Spawner is identified in one of the
ServerFactory MBean's manageServer operations. The name of the registered MBean uses the form: com.sas.services:type=Server,serverType=Spawner,
name="Server Name",
host=Host Name,port=Port
The Spawner MBean enables you to manage and monitor the running Object Spawner.
You can perform SAS Spawner operations such as stop, pause, and resume.
Here are some commonly used Spawner MBean attributes: n the number of times the counters have been reset n the amount of time the server has been idle n the number of currently connected clients n the server start time n the number of currently abandoned servers n the number of currently launched servers n the total number of servers that have been launched n the number of currently failed servers n the process identifier of the server process n the amount of time spent in server method calls n the number of method calls that the server has processed
298
Chapter 18 / Using the SAS Web Infrastructure Platform Utilities
Server MBean
The Server MBean is created whenever a SAS server is identified in one of the
ServerFactory MBean's manageServer operations or when a server is managed via the
Spawner MBean's manageLaunchedServer(s) operation.
A server MBean can represent a SAS Workspace Server, a SAS Stored Process
Server, a SAS Framework Data Server, a SAS Metadata Server, or a SAS OLAP
Server. The name of the registered SAS Server MBean uses one of these three forms: com.sas.services:type=Server, serverType=Workspace, logicalServer=
"LogicalServerName", name="Server Name",
instanceid="Unique instance ID" com.sas.services:type=Server, serverType=StoredProcess, logicalServer=
"LogicalServerName", name="Server Name",
instanceid="Unique instance ID" com.sas.services:type=Server, serverType=Table, logicalServer=
"LogicalServerName", name="Server Name",
host=Host Name,
port=Port Number
The Server MBean enables you to manage and monitor the running SAS server. You can perform server operations such as stop, pause, and resume.
Here are some commonly used Server MBean attributes: n the number of times the counters have been reset n the amount of time the server has been idle n the number of currently connected clients n the server start time n the last time the counters were reset n the execution state of the server n the amount of time spent in server method calls n the number of method calls that the server has processed n the number of clients that the server has serviced n the process identifier of the server process

Overview
The configuration scripting tools enable administrators to perform the following tasks: n
Create the SAS Web Application Server configuration rather than following the
manual instructions. If the automatic configuration option was disabled in the SAS
Deployment Wizard, then the SAS Deployment Wizard provides an Instructions.html file that describes the configuration steps to perform the web application server configuration. You can use the configuration scripting tools to perform these steps automatically instead of manually.
n
Rebuild the web application server configuration. The results are identical to what is performed by the SAS Deployment Wizard and SAS Deployment Manager.
302
Chapter 19 / SAS Configuration Scripting Tools
The SAS configuration scripting tools also enable an administrator to perform the following additional tasks: n
Use a command line to perform a configuration operation on a single resource. For example, creating a server instance can be performed with a single command.
n
Edit property files that are associated with specific resources and then update the resources with the configuration scripting tools.
n
Use existing property files as templates for creating additional resources. For example, an administrator can copy the definitions for SASServer1 to a new file and then use it as a template to create a new server instance.
Special Considerations
n
If you are rebuilding or reconfiguring a web application server, then make sure that all the web application servers are stopped.
n
If you encounter errors while configuring a web application server, review the properties that are being used by the tool and rerun the tool. The tool can be run many times without deleting the configuration between runs, so long as the server is not running. If the server starts in between runs, there can be locks on files that prevent subsequent runs from succeeding.
Scripting Tool for SAS Web Application
Server
Command Syntax
Start, Stop, and Restart Syntax
The syntax for the start, stop, and restart operations is as follows: appsrvconfig.cmd start appsrvconfig.cmd stop
Scripting Tool for SAS Web Application Server
303 appsrvconfig.cmd restart
Note:
For UNIX operating environments, the command is appsrvconfig.sh.
The requested operation is performed on all the SAS Web Application Server instances on the same machine.
The script is located in the SAS-config-dir\Levn\Web\Scripts\AppServer directory.
Command Syntax
The positional command syntax is as follows:
<operation> <resourceType> <targetName> <scope ...>
The following example shows the commands for starting a server and deploying an application: start server SASServer1 global global deploy application SASWIPAdmin9.4 server SASServer1
TIP You can deploy all applications with deploy application all server

Managing Credentials
Credentials are required to configure resources such as data sources and login modules. You can store credentials in the SAS-config-dir\Lev1\Web\Scripts
\AppServer\props\credentials.properties file.
By default, the SAS Deployment Wizard does not persist credentials in the specified file.
When you run the configuration scripting tool, you are prompted for all credentials that are required to configure the resources—but are not specified in the credentials.properties file.
If the option to cache credentials was enabled when the SAS Deployment Wizard was run, then the credentials are stored in the credentials.properties file. In this case, the configuration scripting tool reads the credentials from the file rather than prompting for them. When the Update passwords feature of the SAS Deployment Manager is used, the passwords for the login modules and mail sessions are updated in the credentials file. Passwords for data source definitions are not updated.
Scripting Tool for SAS Web Application Server
305
Log File
Details for the command execution are stored in the SAS-config-dir\Lev1\Web
\Scripts\AppServer\logs\config.log file. The SAS Deployment Wizard invokes the configuration scripting tool, so this file already contains messages for an installed system. This file can be useful for troubleshooting middle-tier configuration tasks performed with the SAS Deployment Wizard and the SAS Deployment Manager.
Rebuilding the SAS Web Application Server
Configuration
You can rebuild the server configuration by running the configuration scripting tool. The tool can re-create the entire configuration and restore it to the originally configured state. The tool configures the resources according to the settings in the props
\appserver.properties file.
Executing a Batch Script
You can supply a file that contains a series of commands for the configuration scripting tool to execute. You can supply a file with different commands to configure different resources. The following example shows the syntax for using the configuration scripting tool with a commands file that is named cmds.txt: appsrvconfig.cmd cmds.txt
The following example shows the commands for undeploying and redeploying the SAS
Web Application Themes: undeploy application SASThemes9.4 server SASServer1 deploy application SASThemes9.4 server SASServer1
If you are creating a resource that requires credentials, such as a data source, remember to create property keys in the credentials.properties file.
Executing a Single Command
You can execute a single command on a single resource from a command line. The following example shows how to undeploy SAS Web Application Themes: appsrvconfig.cmd undeploy application SASThemes9.4 server SASServer1

About the SAS Environment File
A SAS environment file defines the available set of SAS environments for SAS client applications, and is generated during the configuration of the SAS Web Infrastructure
Platform. The SAS Logon Manager includes a servlet that provides default information for the initial deployment. The sas-environment.xml file is automatically deployed on
SAS Web Server at http://hostname.example.com/sas/sas-
environment.xml.
Your site might have requirements that application clients interact with separate development, test, and production environments. Or, you might elect to have separate
SAS deployments to support distinct business units. In either scenario, when multiple environments are required, you can customize and deploy the sas-
environment.xml file as needed.
Make sure that the file is available to SAS desktop clients. In environments that protect
URLs with third-party products like IBM Tivoli Access Manager WebSEAL or CA
SiteMinder, do not protect the URL to the file. The SAS desktop clients that use the fill are unable to respond to a prompt for credentials. In these environments, you can
324
Appendix 1 / Configuring the SAS Environment File
deploy the file from a different HTTP server. Update the SAS desktop clients with the new location if you change it.
Configuring the SAS Environment File
Customizing the SAS Environment File
The sas-environment.xml is located in the SAS-config-dir\Lev1\Web\WebServer
\htdocs\sas directory.
Here is a sample sas-environment.xml file that is configured for two environments:
<?xml version="1.0" encoding="UTF-8">
<environments xmlns="http://www.sas.com/xml/schema/sas-environments-9.4"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.sas.com/xml/schema/sas-environments-9.4
http://www.sas.com/xml/schema/sas-environments-9.4/sas-environments-9.4.xsd"
version="2.0">
<environment name="Red" default="false">
<desc>test server Red for SAS Financial Management Studio</desc>
<service-registry>http://red.example.com:80/SASWIPClientAccess/ remote/ServiceRegistry</service-registry>

<service-registry interface-type="rest">http://blue.example.com:
80/SASWIPClientAccess/rest</service-registry>
</environment>
</environment>
The service registry that is specified in the file enables desktop client applications to determine the location of required services on the middle tier. It also enables the applications to obtain a list of services available in the environment. Note that this sas-
Configuring the SAS Environment File
325 environment.xml file is used by SAS Web Server, and the configuration in the file refers to the host name and port number of SAS Web Server.
If SSL is configured at your site, specify the https protocol and the SSL port number for the service registry.
If your site has multilingual users, you can configure the sas-environment.xml file to include localized descriptions. In the next example, the Blue environment is specified in
German:
<environment name="Blue">
<desc>test2 Blue</desc>
<desc xml:lang="de">Blau</desc>
<service-registry>http://blue.example.com:80/SASWIPClientAccess
/remote/ServiceRegistry</service-registry>
<service-registry interface-type="soap">http://blue.example.com:
80/SASWIPSoapServices/services/ServiceRegistry</service-registry>
<service-registry interface-type="rest">http://blue.example.com:
80/SASWIPClientAccess/rest</service-registry>
</environment>
When the customized sas-environment.xml file is available for multiple environments, see to the documentation for your SAS application or solution for instructions about how to enable the availability of these environments for the users. If you change the location of the sas-environment.xml file, be aware that SAS desktop applications such as SAS
Enterprise Miner need to be updated with the new location. The SAS desktop applications that integrate with the middle tier use the -Denv.definition.location
JVM option in INI files to identify the location of the sas-environment.xml file. Refer the documentation for the SAS desktop applications that you use. The SASHome/
sassw.config file is also used to identify the location of the sas-environments.xml file.
Update the SASENVIRONMENTSURL= value in the sassw.config file.
Element Description
The following list identifies and describes the elements that can be used in the sasenvironment.xml file: environment has a name attribute that cannot contain space characters. This attribute is used internally by SAS software to identify each of the environments that are available in

the deployment. This element has an attribute that is named default. This attribute is used to identify a default environment for client applications. If this attribute is set to true for more than one environment element, then the last environment in the file with the attribute set to true is set as the default environment. It is not necessary to set the attribute to false for all other environments.
desc used in the client applications to provide a menu of environment choices. As shown in the previous example, this field can provide a localized message when the xml:lang attribute is set.

Appendix 2 / Administering Multicast Options
Overview of Multicasting
Multicast communication is used to communicate among SAS middle-tier applications in a single SAS deployment (the set of applications connected to the same SAS Metadata
Server). When installation is performed with the SAS Deployment Wizard, the wizard generates a default multicast address that is based on IP address of the SAS Metadata
Server. The combination of multicast address and multicast UDP port number must be different for each SAS deployment and also different from any other multicast applications at your site.
The multicast communication includes all the information that is needed to bootstrap the
SAS middle-tier applications. Because this information includes the SAS environment credentials (such as the sasadm account name and its password), time to live (TTL) and encryption options are provided to secure the multicast communication.
Multicast options are specified as JVM options. Multicast options provide the ability to tune and change the behavior of the multicast communication that occurs within the
SAS deployment. The multicast address and UDP port number must match the values in the SAS Web Application Server start-up script and the environment.properties file located in the SAS-config-dir\Lev1\Web\Applications\RemoteServices directory.
Administering multicast options typically involves the following: n setting options such as the multicast address n configuring security with a multicast authentication token n configuring the bind address that is used for multicast communication
Multicast Security
329
How Much Multicast Network Traffic is
Generated?
The amount of multicast network traffic that is generated by SAS applications is fairly small. The greatest amount of traffic is generated during application start up. When SAS
Remote Services starts, the largest packet that it generates is 124 bytes. Once startup is complete, the typical rate is less than 64 Kb per hour.
When the web application server starts, the largest packet is 256 bytes. Once startup is complete, the typical rate for an entire SAS Enterprise Business Intelligence Server deployment (including SAS Remote Services) is less than 128 Kb per hour.
Once the applications are generating multicast traffic, the amount of traffic is steady regardless of the load on the SAS Web applications.
Multicast Security
A multicast group communications protocol is used to communicate among middle-tier
SAS applications in a single SAS deployment (the set of applications connected to the same SAS Metadata Server). During installation, the SAS Deployment Wizard supplies you with a default multicast address and port number that it generates based on the machine's (metadata server) IP address. The combination of multicast IP address and multicast UDP port should be different for each SAS deployment and also different from those used by other multicast applications at your site.
The IP address and multicast UDP port number for the multicast host must match the values in the SAS Web Application Server start-up script and the environment.properties file.
The multicast group communication includes all information needed to bootstrap SAS middle-tier applications. Because this includes sending the SAS environment credentials (such as the sasadm account name and its password), scoping and encryption options are provided in the SAS Deployment Wizard. The defaults are most
330
Appendix 2 / Administering Multicast Options
appropriate for deployments in the firewall, isolated data center environment. After installation, if you choose to modify the scoping or encryption options, you can do so by specifying the options for the -Dmulticast.security parameter for the web application server.
For more information, see “Administering Multicast Options” on page 328

Key Multicast Properties
The following table shows some key multicast properties.
Table A2.1 Multicast Properties
Property Default Value Unit
multicast.address
239.X.Y.Z Not applicable multicast.port
8561 Not applicable
Description
This value is provided by the SAS
Deployment Wizard prompting mechanism and defaults to
239.X.Y.Z. Values for X, Y, and Z are the last three octets of the metadata server's IP address.
In an IPv6 environment, the value defaults to ff14::/16.
This value is provided by the SAS
Deployment Wizard prompting mechanism and represents the port on which UDP communication occurs.
332
Appendix 2 / Administering Multicast Options
Property Default Value Unit
multicast_udp_ip_ ttl
1 Decimal. Specifies how far a multicast packet should be forwarded from a sending host.
0 is restricted to the same host.
1 is restricted to the same subnet.
32 is restricted to the same site.
64 is restricted to the same region.
128 is restricted to the same continent.
255 is unrestricted.
Description
The IP multicast routing protocol uses the Time to Live (TTL) field of IP datagrams to decide how far a multicast packet should be forwarded from a sending host.
The default TTL for multicast datagrams is 1, which results in multicast packets going only to other hosts in the local network.
If all SAS applications participating in the multicast (this includes Remote Services, any
Java applications in the middle tier, and BI Report Services) are on the same machine, the value should be 0.
If your site has a SAS middle-tier application that resides on a different subnet but uses the same metadata server within the same SAS deployment, increase the value for this property.
multicast.security
Not applicable Not applicable multicast.config.fil
e
Not applicable URL string (file://, http://, and so on)
By default (with no value), both encryption and authentication are enabled. Valid values are: n ENCRYPT: encrypt but do not require authentication n NONE: do not encrypt and do not require authentication
By default, a JGroups configuration is provided.
However, you can provide your own configuration by specifying the URL path to that configuration. This option enables you to specify a port range or change from IP multicast to the gossip router capabilities of
JGroups.
Configuring a Multicast Authentication Token
333
Configuring a Multicast Authentication
Token
Understanding the Multicast Authentication
Token
By default, the multicast communication is protected with encryption because it conveys credentials. This default setting for encryption uses a fixed encryption key that is built into the software and is common to all SAS middle-tier software. This strategy prevents access to the multicast communication from unauthorized listeners. This setting might be sufficient for deployments where multicast communication is isolated from the user community with a firewall, a TTL option, or the deployment is in an isolated data center.
If your middle tier meets any of the following criteria, then you might want to set a multicast authentication token value: n the middle-tier environment is not well isolated from end-user access n the security procedures at your site require protection among administrative and operational staff in various roles n you want more protection against eavesdroppers and unauthorized participants
For these deployments, set a multicast authentication token value that is known only to the appropriate personnel. A multicast authentication token is a password-like string that is needed to connect to the multicast group and create a site-specific encryption key. In a multi-tier configuration, the SAS Deployment Wizard displays a prompt for a multicast authentication token on each tier that has an application participating in multicast communication. The same authentication token value must be specified for each tier in the same SAS deployment (each tier associated with the same metadata server).
The multicast authentication token has an interaction with the multicast.security property. By default, clients that want to join a multicast group to receive messages are required to provide an authentication token for the join request. (This is true whether a custom token value is used or if the default token value that is built into the software is used.) If you determine this process is causing an impact on performance, or that it is
334
Appendix 2 / Administering Multicast Options
unnecessary, you can disable the use of authentication tokens. If you set the multicast.security property to NONE, encryption and authentication are disabled. If you set the property to ENCRYPT, then encryption is enabled with no authentication of the join request.
Reconfiguring to Use a Multicast
Authentication Token
Generate a Token and Set the Token for SAS Remote Services
1
Use SAS and the PWENCODE procedure to generate an encoded password to use as the multicast authentication token. For example,
{SAS002}DA9A0A5C20629B7F34D2C88A165E5530.
2
Edit the SAS-config-dir\Lev1\Web\Applications\RemoteServices
\RemoteServices.bat file to add a -DMULTICAST_AUTHENTICATION_TOKEN
JVM option.
For Windows, add the option in the runasScripts section:
:runasScripts set MULTICAST_AUTHENTICATION_TOKEN=token
For UNIX and z/OS, add the option to the RemoteServices.sh file after the
SERVERUSER variable:
SERVERUSER=sas
MULTICAST_AUTHENTICATION_TOKEN="token" export MULTICAST_AUTHENTICATION_TOKEN
3

Configuring the JGroups Bind Address
Understanding JGroups the Bind Address
Some SAS middle-tier applications use JGroups to perform multicast communication between applications and to perform caching of application properties. The JGroups software binds to the IP address of first non-loopback network interface that it can detect on the machine. Many machines have multiple network interfaces (multihomed), and each network interface has its own IP address. In some cases, the Web application server selects the value of InetAddress.getLocalHost().getHostName() as the bind address to use for multicast communication and SAS Remote Services selects a different IP address to bind to.
Multicast communication does not function correctly if the IP address selected by
JGroups for SAS Remote Services does not match the IP address selected by the web
