Chapter 1: Managing Identities and Access
This section contains the following topics:
User Management and Application Access (see page 9)
Role-Based Entitlements (see page 10)
Admin Roles for User Account Management (see page 12)
Provisioning Roles for Additional Accounts (see page 15)
Password Management (see page 16)

User Management and Application Access
The typical Information Technology (IT) department faces a constant demand to
maintain user accounts. IT administrators must address urgent needs of users, such as
resetting forgotten passwords, creating new accounts, and providing supplies and office
equipment.
Simultaneously, IT administrators must provide users with various levels of access to
applications. For example, a department manager generates purchase orders and needs
an account in a financial application.
To address the escalating demands on IT, CA Identity Manager provides an integrated
method of managing users and their access to applications, including:
■
Assignment of privileges through roles. Specifically:
–
Roles that enable administrators to create and maintain user accounts
–
Roles that provision additional accounts to existing users (requires provisioning
support)
■
Delegation of the management of users and application access
■
Self-service options so users can manage their own accounts
■
Integration of business applications with CA Identity Manager
■
Options to customize and extend CA Identity Manager
Chapter 1: Managing Identities and Access 9
Role-Based Entitlements
Role-Based Entitlements
You assign privileges to users by assigning roles. A role contains tasks that correspond to
application functions in CA Identity Manager, such as the Create User task, functions in
an application, such a Create Purchase Order function or account templates that give
the user accounts, such as an SAP account. When users are assigned a role, they receive
the corresponding privileges.
CA Identity Manager provides the following types of roles:
■
User management roles, which are called admin roles.
Admin roles can also include any task that appears in the User Console.
■
Account assignment roles, which are called provisioning roles
■
Application function roles, which are called access roles.
If you remove a task or account template from a role, the user can no longer perform
that task, use an endpoint account, or use an application function.
Admin Roles
The admin roles control what a user can do in CA Identity Manager. A system
administrator assigns a role to a user; that role defines a set of tasks that the user can
perform. Users can perform administrative tasks on user accounts, such as changing a
password or updating a job title.
Different users have different levels of access to these tasks. For example, an Employee
role could contains tasks that give users the ability to modify their name and address,
whereas the Human Resources Manager role contains tasks to modify the user's title
and salary.
The following illustration shows four tasks which are combined into one admin role and
assigned to three users:
Task 1
Task 2
Task3
R o le 1
10 Implementation Guide
Task 4
Role-Based Entitlements
Provisioning Roles
To grant users access to accounts in additional applications, such as an email system,
you assign provisioning roles. Provisioning roles contain account templates, which
define the attributes that exist in one type of account. For example, an account
template for an Exchange account defines attributes such as the size of the mailbox.
Account templates also define how CA Identity Manager user attributes are mapped to
accounts.
The following illustration shows four accounts which are combined into one provisioning
role and assigned to three users. Each user receives four accounts, when you assign the
provisioning role to that user
A ccount 1
A ccount 2
A ccount 3
R o le 1
A ccount 4
Access Roles
Access roles provide an additional way to provide entitlements in CA Identity Manager
or another application. For example, you can use access roles to accomplish the
following:
■
Provide indirect access to a user attribute
■
Create complex expressions
■
Set an attribute in a user profile, which is used by another application to determine
entitlements
Chapter 1: Managing Identities and Access 11
Admin Roles for User Account Management
Access roles are similar to identity policies in that they apply a set of business changes
to a user or group of users. However, when you use an access role to apply business
changes, you can see which users the changes apply to by viewing the members of the
access role.
In most cases, access roles are not associated with tasks.
Note: When CA Identity Manager integrates with CA SiteMinder, access roles can also
provide access to applications that are protected by CA SiteMinder. In this case, access
roles do include access tasks. For more information, see the chapter on SiteMinder
integration in the Configuration Guide.
Admin Roles for User Account Management
In CA Identity Manager, you manage user store objects (users, groups, and
organizations) through admin roles. You also use admin roles to manage the roles and
tasks through which you manage user store objects. For example, you use admin roles
to modify profile attributes of users, give users options for managing their own
accounts, and to approve tasks that use workflow.
12 Implementation Guide
Admin Roles for User Account Management
Profile Management at the Attribute Level
You can create admin roles for different administrators who need to read or write
different profile attributes. For example, a company may have several employees who
perform operations on user profiles, each accessing different attributes. The following
figure shows three roles and their associated tasks. Each role has different access to
profile attributes.

In this example, three roles can manage different attributes for the same user, Dan
Walton:
■
A Help Desk administrator views user names and addresses and resets user
passwords.
■
A Human Resources administrator modifies user IDs, user names, addresses, titles,
and number of vacation days.
■
An IT manager modifies the title of users and views their name and number of
vacation days.
Chapter 1: Managing Identities and Access 13
Admin Roles for User Account Management
Whatever roles you have when you log in to CA Identity Manager, a series of tabs, called
categories, appear based on the admin role assigned to your CA Identity Manager
account. You click a tab to see the tasks that you can perform in that category as shown
in the following figure:
The categories and the tasks in those categories that a user sees are determined by the
user's admin roles.
Workflow Approval of Admin Tasks
To help automate business processes, you can design an admin task to generate a
workflow process. A workflow process automates a well-defined procedure that a
company repeats frequently. CA Identity Manager includes the WorkPoint workflow
engine.
14 Implementation Guide
Provisioning Roles for Additional Accounts
Workflow processes are triggered by CA Identity Manager events which are part of an
admin task. For example, the Create User task includes events called CreateUserEvent
and AddToGroupEvent. When an event occurs, the workflow engine can:
■
Require approvals--An approver must approve an event, such as modifying a user
profile, before CA Identity Manager updates a user store. Approvers are
administrators who have the Approver role for a particular task.
■
Send notifications--The workflow engine can notify users of an event’s status at
different stages of a process, such as when a user initiates an event or when an
event is approved.
■
Generate work lists--Work lists specify the tasks that a particular user must
perform. The workflow engine updates administrators’ work lists automatically.
For common events, you can use the workflow processes supplied with CA Identity
Manager. Alternatively, you can create custom workflow processes.
Provisioning Roles for Additional Accounts
In CA Identity Manager, you provide additional accounts to users by using provisioning
roles. Provisioning roles contain account templates, which define accounts that exist in
managed endpoints, such as an email server. Once you have users in CA Identity
Manager, you can assign provisioning roles to some of those users. The user receives
the accounts defined by the templates in the role.
The account templates define the characteristics of the account. For example, an
account template for an Exchange account might define the size of the mailbox. The
account templates also define how user attributes are mapped to accounts.
To be able to use provisioning roles, you must install the Provisioning Server with the CA
Identity Manager server. Then, you create account templates in the User Console.
Chapter 1: Managing Identities and Access 15
Password Management
Password Management
CA Identity Manager includes several features for managing user passwords:
■
Password Policies—These policies manage user passwords by enforcing rules and
restrictions governing password expiration, composition, and usage.
Note: For advanced password policies, configure integration with SiteMinder. For
more information, see the Installation Guide.
■
Password Managers—Administrators who have the Password Manager role can
reset a password when a user calls the Help desk.
■
Self-Service Password Management—CA Identity Manager includes several
self-service tasks that allow users to manage their own passwords. These tasks
include:
■
■
Self Registration—Users specify a password when they register at a corporate
web site.
■
Change My Password—Users can modify their passwords without help from IT
or Help Desk personnel
■
Forgotten Password—Users can reset or retrieve a forgotten password after CA
Identity Manager verifies their identity.
■
Forgotten User ID—Users can retrieve a forgotten user ID after CA Identity
Manager verifies their identity.
Password Synchronization (for use with provisioning only)—Password changes are
synchronized in CA Identity Manager and in accounts on target systems called
endpoints. New passwords are verified against CA Identity Manager password
policies.
Self Service Options for Users
To further reduce the IT workload, CA Identity Manager includes features for registering
new users and supplying a forgotten password. These features require no administrator
involvement. The user gains access to CA Identity Manager through a public console,
which requires no login account. Through this console, a user can self-register at a site
or request a reminder about a forgotten password.
To save the time of IT administrators, CA Identity Manager users can manage their own
accounts. Because users have a self-management role, they can:
16 Implementation Guide
■
Maintain personal information
■
Change their own password
■
Join self-subscribing groups
Customization and Extensibility
Customization and Extensibility
You customize these CA Identity Manager features:
■
The CA Identity Manager directory, which describes a user store structure to CA
Identity Manager.
■
The appearance and functionality of the user interface.
■
User entry screens, which determine the fields and layout of each task screen.
■
Validation of user data entry, through regular expression, JavaScript, or Java
implementations.
■
Workflow, which defines automated workflow processes. Create or modify
processes by linking approvers and actions in the WorkPoint Process Designer.
■
Email messages, which inform users of a task’s status.
■
Task submission, which can be sent by a third-party application to the CA Identity
Manager Task Execution Web Service (TEWS). TEWS processes the remote task
request. Remote task requests comply with WSDL standards.
You can extend CA Identity Manager’s functionality using the following APIs:
■
Logical Attribute API—Enables you to display an attribute differently than how it is
stored physically in a user directory.
■
Business Logic Task Handler API—Allows you to perform custom business logic
during data validation or transformation operations.
■
Workflow API—Provides information to a custom script in a workflow process. The
script evaluates the information and determines the path of the workflow process
accordingly.
■
Participant Resolver API—Enables you to specify the list of participants who are
authorized to approve a workflow activity.
■
Event Listener API—Enables you to create a custom event listener that listens for a
specific CA Identity Manager event or group of events. When the event occurs, the
event listener can perform custom business logic.
Chapter 1: Managing Identities and Access 17
CA Identity Governance Integration
■
Notification Rule API—Lets you determine the users who should receive an email
notification.
■
Email Template API—Includes event-specific information in an email notification.
Note: For more information on the CA Identity Manager APIs, see the Programming
Guide for Java.
When CA Identity Manager includes provisioning, you can also extend provisioning
functionality as follows:
■
Custom connectors—Enable communication between a Provisioning Server and an
endpoint system. The code that makes up a connector can include a GUI plug-in,
server plug-in, and agent plug-in.
A dynamic connector can be generated by Connector Xpress, and a custom static
connector can be developed in Java or C++.
Note: For more information, see the Connector Xpress Guide.
■
Program exits—Let you reference custom code from the Provisioning Server
process flow.
Note: For more information about extending provisioning functionality, see the
Programming Guide for Provisioning, which is available in the Legacy Components
media.
CA Identity Governance Integration
CA Identity Governance is an identity lifecycle management product that enables you to
quickly and accurately develop, maintain, and analyze role models. It also provides
centralized identity compliance policy controls and automates processes associated with
meeting compliance and security demands. Using CA Identity Governance, you can do
the following:
18 Implementation Guide
■
Validate that CA Identity Manager user privileges are granted in accordance with
business compliance policies
■
Get suggested roles and compliance checking when creating or modifying CA
Identity Manager users, roles, and accounts
■
Understand what roles exist in your organization, establish a role model that fits
your organization, and re-create the desired role model within CA Identity Manager
■
Analyze and maintain that role model as business evolves
CA User Activity Reporting Integration
CA Identity Manager integrates with CA Identity Governance in two ways:
■
CA Identity Governance Connector for CA Identity Manager
A special type of connector that automatically synchronizes the privilege data
between CA Identity Manager and CA Identity Governance. By using this connector,
you can import data from CA Identity Manager to CA Identity Governanceor export
data from CA Identity Governance to CA Identity Manager.
■
Smart Provisioning
When CA Identity Manager integrates with CA Identity Governance, you can
configure additional functionality that allows you to use role and compliance
information, which is available in a role model, to support day-to-day identity
management operations. Changes made in CA Identity Manager dynamically
update the role model in CA Identity Governance.
Note: For more information about CA Identity Governance integration with CA Identity
Manager, see the CA Identity Manager Integration Guide found in the CA Identity
Governance bookshelf.
CA User Activity Reporting Integration
Beginning at CA Identity Manager r12.6, CA Enterprise Log Manager is called CA User
Activity Reporting (CA UAR).
CA UAR uses the CA Common Event Grammar (CEG) to map events that originate in
various systems in a standard format, and stores all events, even those which are not
yet mapped, for review and analysis. Furthermore, CA UAR provides users with a
high-volume solution for managing and reporting on collected data, using configurable
database queries and/or reports to search for various types of information and events.
CA UAR provides better wider and deeper insight into un-managed systems and systems
outside of CA Identity Manager's purview and control and also lets you investigate
deeper into identities.
Integrating with CA Identity Manager lets you view CA UAR identity centric reports
and/or dynamic queries into CA UAR user Console using the CA Identity Manager User
Console. From the User Console you can configure how existing CA Identity Manager/CA
UAR reports and/or queries are viewed and modified while you investigate deeper into
a specific identity.

Chapter 2: Addressing Business Needs
This section contains the following topics:
Processing Business Changes (see page 21)
Complying with Business Policies (see page 22)
Enforcing Segregation of Duties Requirements (see page 25)
Transforming Data in the User Store (see page 26)
Applying Custom Business Logic (see page 27)
Approving Business Changes (see page 28)
Processing Business Changes
You can automate the processing of certain identity management tasks by using identity
policies. An identity policy is a set of business changes that occurs when a user meets a
certain condition or rule. You can use identity policy sets to:
■
Automate certain identity management tasks, such as assigning roles and group
membership, allocating resources, or modifying user profile attributes.
■
Enforce segregation of duties (see page 25). For example, you can create an identity
policy set that prohibits members of the Check Signer role from having the Check
Approver role, and restricts anyone in the company from writing a check over
$10,000.
■
Enforce compliance. For example, you can audit users who have a certain title and
make more than $100,000.
Identity policies that enforce compliance are called compliance policies.
The business changes associated with an identity policy include:
■
Assigning or revoking roles, including provisioning roles (when CA Identity Manager
includes provisioning)
■
Assigning or revoking group membership
■
Updating attributes in a user profile
For example, a company may create an identity policy which states that all Vice
Presidents belong to the Country Club Member group and have the role Salary
Approver. When a user’s title changes to Vice President and that user is synchronized
with the identity policy, CA Identity Manager adds the user to the appropriate group
and role. When a Vice President is promoted to CEO, she no longer meets the condition
in the Vice President identity policy so the changes applied by that policy are revoked,
and new changes based on the CEO policy are applied.
Chapter 2: Addressing Business Needs 21
Complying with Business Policies
The change actions that occur based on an identity policy contain events which can be
placed under workflow control and audited. In the previous example, the Salary
Approver role grants significant privileges to its members. To protect the Salary
Approver role, the company can create a workflow process that requires a set of
approvals before the role is assigned, and they can configure CA Identity Manager to
audit the role assignment.
To simplify identity policy management, identity policies are grouped in an identity
policy set. For example, the Vice President and CEO policies may be part of the
Executive Privileges identity policy set.
Complying with Business Policies
Compliance is a corporate governance that includes a wide range of procedures that
ensure a company and its employees comply with business policies. These compliance
procedures often involve documenting, automating, and auditing the allocation of
entitlements to applications and systems.
CA Identity Manager includes the following features, which support compliance
management:
■
Smart Provisioning
Smart Provisioning is a collection of functionality that simplifies provisioning role
assignment when CA Identity Manager integrates with CA Identity Governance. This
functionality includes:
■
Suggested Provisioning Roles
CA Identity Manager can provide administrators with a list of provisioning roles
that may be appropriate to assign to a user. The list of provisioning roles is
determined by CA Identity Governance, based on criteria entered by the
administrator.
Suggested provisioning roles help ensure that users have the correct privileges,
while maintaining a company's role model.
■
Compliance and Pattern Messages
CA Identity Manager administrators can validate proposed changes against a
role model in CA Identity Governance before committing changes. Validating
changes before they are committed helps companies maintain the role model
that they have defined for their operations.
Users can validate proposed changes to provisioning roles (assigning or
removing them), and changes to user attributes.
22 Implementation Guide
Complying with Business Policies
CA Identity Manager performs two types of policy validations:
–
Compliance
Proposed changes are validated against the CA Identity Governance role
model to see if they violate explicit, predefined business policy rules in CA
Identity Governance.
–
Pattern
Proposed changes are compared to the CA Identity Governance role model
to see if they cause the subject of the change to become "out of pattern."
CA Identity Manager also makes sure that the changes do not significantly
alter an established pattern in the role model.
You can configure CA Identity Manager to perform these validations
automatically when users perform certain tasks, or allow users to initiate
the validation manually.
You can implement Smart Provisioning in a CA Identity Manager Environment once
there is an established role model, based on CA Identity Manager data, in CA
Identity Governance.
Note: For more information, see the Administration Guide.
■
Identity policies
You can create a compliance policy, a type of identity policy (see page 21), which
prohibits users from having certain privileges if they have other privileges. For
example, you can prohibit users who can approve checks from issuing checks.
Compliance policies enforce a segregation of duties in your environment.
■
Compliance reports
CA Identity Manager includes sample reports that display the compliance status for
users in your environment. Using these reports, you can see which users are not
compliant with your business policies.
Compliance Reports
CA Identity Manager includes the sample reports in the following table that you can use
to monitor compliance with corporate business policies.

Enforcing Segregation of Duties Requirements
Segregation of Duties (SOD) requirements prevent users from receiving privileges that
may result in a conflict of interest or fraud. CA Identity Manager provides the following
functionality to support SOD:
■
Preventative identity policies
These policies, which execute before a task is submitted, allow an administrator to
check for policy violations before assigning privileges or changing profile attributes.
If a violation exists, the administrator can clear the violation before submitting the
task.
For example, a company can create a preventative identity policy that prohibits
users who have the User Manager role from also having the User Approver role. If
an administrator uses the Modify User task to give a User Manager the User
Approver role, CA Identity Manager displays a message about the violation. The
administrator can change the role assignments to clear the violation before
submitting the task.
Chapter 2: Addressing Business Needs 25
Transforming Data in the User Store
■
Policy Validation through Smart Provisioning
CA Identity Manager administrators can validate proposed changes to provisioning
roles and user attributes against Business Policy Rules (BPRs) in CA Identity
Governance before committing changes. BPRs represent various constraints on
privileges. For example, a BPR may prevent users who have a purchasing
department role, which allows members to order stock from subcontractors, from
also having the subcontractor payment role. A system administrator, business
manager, auditor, or role engineer creates BPRs in CA Identity Governance.
Note: For more information about BPRs, see the CA Identity Governance Sage DNA
User Guide.
Note: For more information about preventative identity policies and Smart Provisioning,
see the CA Identity Manager Administration Guide.
Transforming Data in the User Store
In some cases, you may want CA Identity Manager to transform data before it is stored
in the user store. For example, you may want to store information in a different format
than it is entered, or you may want changes applied when certain types of information
are present.
CA Identity Manager includes the following features for transforming data:
■
Identity Policies
■
Logical Attribute Handlers
Note: You can also use identity policies and logical attribute handlers to implement
custom business logic.
Logical Attribute Handlers
Logical attribute handlers are custom Java code that transform user attribute values
used on CA Identity Manager task screens. Using logical attribute handlers, you can
control how a physical attribute is displayed on a task screen. You can also use logical
attribute handlers to transform a display value, such as cost, on the task screen to one
or more physical attributes, such as unit price and quantity, that are stored in the user
store.
Note: For more information about logical attribute handlers, see the Programming
Guide for Java.
26 Implementation Guide
Applying Custom Business Logic
Applying Custom Business Logic
You can customize CA Identity Manager to implement the business logic that your
company requires. CA Identity Manager includes the following options for implementing
custom business logic:
■
Identity Policies—You can use identity policies to define a set of business changes
that occur when a user meets a certain condition or rule. For example, identity
policies can automate certain identity management tasks, such as assigning roles,
or enforce business rules, such as preventing users from signing and approving
checks over $20,000.
Note: For more information about identity policies, see the Administration Guide.
■
Logical Attribute Handlers—You can associate these handlers with CA Identity
Manager task screens to control the display and modification of attribute values.
For more information, see the Programming Guide for Java.
■
Business Logic Task Handlers—Enable you to perform custom business logic, such
as the following, during data validation operations for a CA Identity Manager task:
–
Enforcing custom business rules (for example, an administrator cannot be
allowed to manage more than five groups).
–
Validating customer-specific task screen fields (for example, the value of an
Employee ID field must exist in the master Human Resources database).
Business logic task handlers can be implemented in Java or JavaScript.
Note: For more information, see the Programming Guide for Java.
■
Workflow—Allows you to create custom process definitions, which are associated
with a CA Identity Manager event.
Note: Before deciding whether to implement business logic in a business logic task
handler or a workflow process, see the following sections:
■
Business Logic Task Handler Considerations (see page 28)
■
Workflow Process Considerations (see page 28)
Chapter 2: Addressing Business Needs 27
Approving Business Changes
Business Logic Task Handler Considerations
Business Logic Task Handlers perform business logic validation during the synchronous
processing phase of the task, which occurs prior to event generation. This allows you to:
■
Perform task-level validation. For example, you can add or remove members of a
group based on their office location, which is specified in the user profile screen.
■
Prevent a task from being submitted if the validation fails.
■
Automatically transform all of the information on a task screen so that it conforms
to your business policies prior to task submission.
Note: You should not implement activities that take a long time to complete in a
Business Logic Task Handler. Long running activities delay the submission of the task and
are not well-suited for the synchronous phase where user interaction occurs. Instead,
use a workflow process, which executes during the asynchronous phase of the task.
Workflow Process Considerations
Workflow processes are called during the asynchronous phase of the task and are
associated with the execution of individual events. This allows you to:
■
Execute approval activities based on the individual event data
■
Execute long running custom business logic activities
While the Workflow API allows you to obtain task-level data from a Workflow Activity,
typically you are operating in the context of that specific event under workflow.
Approving Business Changes
Workflow describes a process that consists of one or more steps that must be
performed in order to accomplish some business objective, such as executing a hiring
procedure, or obtaining a user’s credit score from an external system. Typically, one of
the steps in a workflow process involves approving or rejecting the business change.
28 Implementation Guide
Approving Business Changes
In CA Identity Manager, a workflow process is associated with an event, an action that
occurs during task processing. When an event enters the Pending state in its lifecycle,
CA Identity Manager invokes any associated workflow process and pauses the event
execution until the process completes. CA Identity Manager then performs or rejects
the event based on the results of the workflow process.
This sequence is shown in the following diagram:
CA Identity Manager includes the InSession WorkPoint workflow engine for creating and
managing workflow processes.
Note: For more information, see the Administration Guide.
Chapter 2: Addressing Business Needs 29
Chapter 3: CA Identity Manager
Architecture
This section contains the following topics:
CA Identity Manager Components (see page 31)
Sample CA Identity Manager Installations (see page 39)
CA Identity Manager Components
A CA Identity Manager implementation may include some or all of the following
components:
■
Servers
■
User Stores
■
Databases
■
Connectors
Servers
A CA Identity Manager implementation includes one or more types of servers,
depending on the functionality you need.
CA Identity Manager Server (required)
Executes tasks within CA Identity Manager. The J2EE CA Identity Manager
application includes the Management Console and the User Console.
CA Identity Manager Provisioning Server
Manages accounts on endpoint systems.
This server is required if the CA Identity Manager installation will support account
provisioning.
Note: You must have the Provisioning Directory installed remotely (or locally for a
demonstration environment only) on a CA Directory Server before installing the
Provisioning Server.
SiteMinder Policy Server
Provides advanced authentication for CA Identity Manager, and provides access to
SiteMinder features, such as Password Services and Single Sign-On.
This server is optional.
Chapter 3: CA Identity Manager Architecture 31
CA Identity Manager Components
User Store and Provisioning Directory
CA Identity Manager coordinates two user stores:
■
The CA Identity Manager user store, the user store maintained by CA Identity
Manager. Typically, this is an existing store that contains the user identities that a
company needs to manage.
The user store can be an LDAP directory or a relational database.
In the Management Console, you create a CA Identity Manager Directory object to
connect to the user store and to describe the user store objects that CA Identity
Manager will maintain.
■
The Provisioning Directory, the user store maintained by the Provisioning Server.
It is an instance of CA Directory and includes global users, which associate users in
the Provisioning Directory with accounts on endpoints such as Microsoft Exchange,
Active Directory, and SAP.
Only some CA Identity Manager users have a corresponding global user. When a CA
Identity Manager user receives a provisioning role, the Provisioning Server creates a
global user.
32 Implementation Guide
CA Identity Manager Components
Separate User Store and Provisioning Directories
The following figure shows a separate user store and Provisioning Directory, which is the
supported scenario for a new installation of CA Identity Manager. In this figure:
■
A CA Identity Manager administrator uses an admin task that edits a user in the
user store, which affects the Provisioning Directory.
This change may also update an endpoint (such as an email server) which has a
connector to the Provisioning Server.
A change made in the Provisioning Server (or an endpoint with a connector to the
Provisioning Server) updates the CA Identity Manager user store and Provisioning
Directory.
For example, an endpoint, such as a Human Resources application, might update the
email addresses of users.
Databases
CA Identity Manager uses data sources to connect to databases that store information
required to support CA Identity Manager functionality. These databases can reside in a
single physical instance of a database, or in separate instances.
Object Database (required)
Contains CA Identity Manager configuration information.
Chapter 3: CA Identity Manager Architecture 33
CA Identity Manager Components
Task Persistence Database (required)
Maintains information about CA Identity Manager activities and their associated
events over time. This allows the system to accurately track CA Identity Manager
activities, even if you restart the CA Identity Manager Server.
Archive Database (required)
Archives data from Task Persistence Database.
Workflow Database
Stores workflow process definitions, jobs, scripts, and other data required by the
Workflow Engine.
Audit Database
Provides a historical record of operations that occur in a CA Identity Manager
environment.
Note: You can configure the amount and type of information that CA Identity
Manager stores in the audit database. See the Configuration Guide for more
information.
Reporting Database
Stores snapshot data, which reflects the current state of objects in CA Identity
Manager at the time the snapshot is taken. You can generate reports from this
information to view the relationship between objects, such as users and roles.
When you use the Installer, CA Identity Manager configures a connection to a single
database, called the CA Identity Manager Database, which contains the tables for each
database type.
Note: You can create a data store for task persistence, workflow, auditing, or reporting
in a separate database and configure CA Identity Manager to connect to it. For more
information, see the Installation Guide.
Connector Components
A connector is the software interface to an endpoint. The Provisioning Server uses the
connector to communicate with the endpoint. It translates Provisioning Server actions
into changes on the endpoint, such as “Create a new email account on a Microsoft
Exchange endpoint.”
Examples of endpoints are UNIX workstation, Windows PC, or an application such as
Microsoft Exchange (for email).
34 Implementation Guide
CA Identity Manager Components
Connector Servers
A connector server is a Provisioning Server component that manages connectors. It can
be installed on the Provisioning Server system or on a remote system.
A Connector Server works with multiple endpoints. For example, if you have many UNIX
workstation endpoints, you might have one Connector Server that handles all
connectors that manage UNIX accounts. Another Connector Server might handle all
connectors that request Windows accounts.
The distributed Connector Server works with multiple Connector Servers. It provides
load balancing when one Connector Server is busy and high availability when a
Connector Server is down.
There are two types of connector servers:
■
CA IAM Connector Server (CA IAM CS) manages connectors written in Java
■
C++ Connector Server (CCS) manages connectors written in C++
C++ Connector Server
The C++ Connector Server is a connector server that manages C++ connectors. It can be
installed on the Provisioning Server or on a remote system. The C++ Connector Server
provides an object-oriented application framework that simplifies development of
connectors, which are responsible for communication between the C++ Connector
Server and the endpoint.
CA IAM CS
CA IAM CS is a server component which handles hosting, routing to, and management of
Java connectors. CA IAM CS provides a Java alternative to the C++ Connector Server. It is
architecturally and functionally similar to the C++ Connector Server, except that it has a
Java API instead of a C++ API, which allows your connectors to be implemented in Java.
In addition, CA IAM CS is data-driven rather than code-driven, which allows more
functionality to be addressed by the container (or CA IAM CS) instead of by connectors
themselves.
The Provisioning Server handles provisioning of users, and then delegates to connectors
(using the C++ Connector Server or CA IAM CS) to manage endpoint accounts, and
groups.
Chapter 3: CA Identity Manager Architecture 35
CA Identity Manager Components
Connectors and Agents
CA Identity Manager Connectors run as part of the wider Provisioning Server
architecture and communicate with the systems managed in your environment. A
connector acts as a gateway to a native endpoint type system technology. For example,
machines running Active Directory Services (ADS) can be managed only if the ADS
connector is installed on a Connector Server with which the Provisioning Server can
communicate. Connectors manage the objects that reside on the systems. Managed
objects include accounts, groups, and optionally, endpoint type-specific objects.
Connectors are installed on the Connector Server and some components are installed
on the Provisioning Server (for example, Server plug-in) or Provisioning Manager (user
interface plug-ins).
Some connectors require an agent on the systems they manage in order to complete
the communication cycle, in which case, they can be installed using the Provisioning
Installer. Agents can be separated into the following categories:
Remote Agents
Installed on the managed endpoint systems
Environment Agents
Installed on systems, such as CA ACF2, CA Top Secret, and RACF
Certain components work on UNIX and Windows, including the following C++ Connector
Server-based options:
■
UNIX (ETC, NIS)
■
Access Control (ACC)
Note: The UNIX ACC connector can manage only UNIX ACC endpoints. The Windows
ACC connector is required to manage the Windows ACC endpoints but can also
manage UNIX ACC endpoints.
■
CA-ACF2
■
RACF
■
CA-Top Secret
The other C++ Connector Server-based connectors can be accessed from the Solaris
Provisioning Server by relying on the Connector Server Framework (CSF). The CSF allows
a Provisioning Server on Solaris to communicate with connectors running on Windows.
Note: The CSF must run on Windows to use these connectors.
36 Implementation Guide
CA Identity Manager Components
Connector Xpress
Connector Xpress is CA Identity Manager utility for managing dynamic connectors,
mapping dynamic connectors to endpoints, and establishing routing rules for endpoints.
You can use it to configure dynamic connectors to allow provisioning and management
of SQL databases and LDAP directories.
Connector Xpress lets you create and deploy custom connectors without the technical
expertise generally required when creating connectors managed by the Provisioning
Manager.
You can also set up, edit, and remove a connector server configuration (both Java and
C++) using Connector Xpress.
The primary input into Connector Xpress is the native schema of an endpoint system.
For example, you can use Connector Xpress to connect to a RDBMS and retrieve the SQL
schema of the database. You can then use Connector Xpress to construct mappings
from those parts of the native schema that are relevant to identity management and
provisioning. A mapping describes how the provisioning layer represents an element of
the native schema.
Connector Xpress generates metadata that describes, to a dynamic connector, the
runtime mappings to a target system.
The output of Connector Xpress is a metadata document produced when you complete
your mappings. The metadata is an XML file that describes the structure of your
connector to CA IAM CS.
It describes the Provisioning Server classes and attributes and how they are mapped to
the native schema.
The metadata is used to create dynamic endpoint types on one or more Provisioning
Servers.
Note: For more information on using Connector Xpress, see the Connector Xpress Guide,
in the CA Identity Manager bookshelf.
Additional Components
CA Identity Manager includes some additional components, which support CA Identity
Manager functionality. Some of these components are installed with CA Identity
Manager and some must be installed separately.
Chapter 3: CA Identity Manager Architecture 37
CA Identity Manager Components
WorkPoint Workflow
WorkPoint workflow engine and WorkPoint Designer are installed automatically when
you install CA Identity Manager.
These components enable you to place a CA Identity Manager task under workflow
control, and to modify existing workflow process definitions or create new definitions.
Note: For more information about workflow, see the Administration Guide.
Provisioning Manager
The CA Identity Manager Provisioning Manager manages the Provisioning Server
through a graphical interface. This is used for administrative tasks such as managing
Provisioning Server options. In some cases, you may also use the Provisioning Manager
to manage certain endpoint attributes, which you cannot manage in the CA Identity
Manager User Console.
The Provisioning Manager is installed as part of the CA Identity Manager Administrative
Tools.
Note: This application runs on Windows systems only.
For more information about the Provisioning Manager, see Provisioning Reference
Guide.
Report Server
CA Identity Manager provides reports that you can use to monitor the status of a CA
Identity Manager environment. To use the reports provided with CA Identity Manager,
you install the Report Server, which is included with CA Identity Manager.
Report Server is powered by Business Objects Enterprise XI. If you have an existing
Business Objects server, you can use that instead of the Report Server to generate CA
Identity Manager reports.
Note: For installation instructions, see the Installation Guide.
38 Implementation Guide
Sample CA Identity Manager Installations
Sample CA Identity Manager Installations
With CA Identity Manager, you can control user identities and their access to
applications and accounts on endpoint systems. Based on the functionality you need,
you select which CA Identity Manager components to install.
In all CA Identity Manager installations, the CA Identity Manager Server is installed on an
application server. You use the CA Identity Manager Installer to install the other
components you need.
The following sections illustrate some examples of CA Identity Manager
implementations at a high level.
Installation with Provisioning Components
CA Identity Manager provisioning allows you to create an Environment that connects to
a Provisioning Server for provisioning accounts to various endpoint systems. You can
assign provisioning roles to users you create through CA Identity Manager. Provisioning
roles are roles with account templates that define accounts that users can receive on
endpoint systems. Accounts provide users with access to additional resources, such as
an email account.
When you assign a provisioning role to a user, that user receives the accounts defined
by the account templates in the role. The account templates also define how user
attributes are mapped to accounts. The accounts are created in managed endpoints
defined by the account templates.
Chapter 3: CA Identity Manager Architecture 39
Sample CA Identity Manager Installations
The following figure is an example of a CA Identity Manager installation with
provisioning:
40 Implementation Guide
Sample CA Identity Manager Installations
Installation with SiteMinder Policy Server
A SiteMinder Policy Server provides advanced authentication and protection for your CA
Identity Manager environment. The following figure is an example of a CA Identity
Manager installation with a SiteMinder Policy Server:
A CA Identity Manager implementation that includes SiteMinder includes all of the
components of the basic installation or the installation with provisioning, plus these
additional components:
SiteMinder Web Agent
Works with the SiteMinder Policy Server to protect the User Console. The Web
Agent is installed on the system with the CA Identity Manager Server.
SiteMinder Policy Server
Provides advanced authentication and authorization for CA Identity Manager, and
other functionality such as Password Services and Single-Sign On.
Chapter 3: CA Identity Manager Architecture 41
Sample CA Identity Manager Installations
Extensions for SiteMinder Policy Server
Enables a SiteMinder Policy Server to support CA Identity Manager. Install the
extensions on each SiteMinder Policy Server system in your CA Identity Manager
implementation.
SiteMinder Policy Store
Stores information that SiteMinder needs to manage access to Web resources.
When CA Identity Manager integrates with SiteMinder, the policy store also
includes information about CA Identity Manager directories and environments so
that SiteMinder can provide advanced authentication.
Note: The components are installed on different platforms as examples. However, you
can choose other platforms. The CA Identity Manager databases are on Microsoft SQL
Server and the user store is on IBM directory Server. The SiteMinder Policy Store is on
AD LDS on Windows.
42 Implementation Guide
Chapter 4: Planning Your Implementation
To plan a CA Identity Manager implementation, you decide how CA Identity Manager
will manage users and what functionality you need to accomplish your business
objectives. Some questions to consider are:
■
How do I manage users?
■
Do I need account provisioning?
■
What are my custom business requirements and should I implement them using
workflow?
Based on the decisions you make, you can determine the best way to implement CA
Identity Manager for your environment.
This section contains the following topics:
Decide What to Manage (see page 43)
Determine Audit Requirements (see page 47)
Decide User Store Requirements (see page 49)
Select Components to Install (see page 50)
Decide Hardware Requirements (see page 51)
Choose a Method to Import Users (see page 54)
Develop a Deployment Plan (see page 57)
Decide What to Manage
Deciding what you want to manage will help you determine which components you
want to install. Using CA Identity Manager, you can manage the following:
■
User identities
■
Access to accounts on endpoint systems
User Identities
User identities represent the people that a company needs to manage, such as
employees, contractors, suppliers, and others.
To manage user identities, you need to install only the CA Identity Manager Server and
the Administrative Tools.
Chapter 4: Planning Your Implementation 43
Decide What to Manage
How to Configure User Management Support
In CA Identity Manager, you manage users with admin roles, which determine the CA
Identity Manager tasks that administrators can perform.
Note: Before implementing user management in CA Identity Manager, you should
determine which functionality you need and develop a plan (see page 57) for
implementing that functionality in stages.
To configure user management support, you complete the following high-level steps:
1.
Install the CA Identity Manager Server and Administrative tools.
If you need to provision accounts to managed users, you will also need to install
support for provisioning (see page 45).
Note: See the Installation Guide for instructions.
2.
Create the following in the CA Identity Manager Management Console:
■
CA Identity Manager directory
Describes a user store to CA Identity Manager. It includes the following:
■
–
A pointer to a user store, which stores managed objects such as users,
groups, and organizations.
–
Metadata that describes how managed objects are stored in the directory
and represented in CA Identity Manager.
CA Identity Manager environment
Provides a management namespace that lets CA Identity Manager
administrators manage objects such as users, groups, and organizations, with a
set of associated roles and tasks. The CA Identity Manager environment
controls the management and graphical presentation of a directory.
For more information about CA Identity Manager directories and environments, see
the Configuration Guide.
3.
Modify the default admin roles and tasks to suit your business requirements.
Typical role modifications include adding or removing default tasks from existing
admin roles, or creating new admin roles, which are based on the default roles.
Typical task modifications include customizing the default user profile tabs to
include only the information that you want to manage. (The default profile tabs
include all attributes that are defined for users.)
For information about modifying the default admin roles and tasks, see the User
Console Design Guide.
4.
44 Implementation Guide
Assign the admin roles to users who will perform user management tasks.
Decide What to Manage
Provisioning Accounts from Other Applications
The decision to implement provisioning depends on the type of information that you
need to manage. If you are managing a central user directory and you do not want to
manage user accounts in other systems, you do not need provisioning. If you want to
manage user accounts over a variety of systems, then you should implement
provisioning support.
Provisioning capabilities are provided through the Provisioning Server, which is
integrated with CA Identity Manager. The Provisioning Server provides the following
functionality for account provisioning:
■
Endpoint Management
■
Account Synchronization
■
Account Templates
■
Explore and Correlate Functionality
Note: Provisioning information is stored in a Provisioning Directory. If CA Identity
Manager maintains users in another type of directory, your deployment will include a
CA Identity Manager user store and a provisioning directory.
Endpoint Management
To provision accounts, you define and manage endpoints in the CA Identity Manager
User Console. An endpoint is a system for which users need access. Examples of
endpoints include Oracle databases, UNIX NIS servers, Windows servers, and Microsoft
Exchange servers. Use Account templates (see page 46) to create accounts and
determine the user capabilities in managed endpoints.
Note: You can also use the Provisioning Manager to define and manage endpoints.
Although we recommend using the User Console for most endpoint management tasks,
there are some tasks that require the Provisioning Manager, such as managing certain
endpoint attributes and managing endpoint objects other than accounts. For more
information about the Provisioning Manager, see the Provisioning Reference.
Account Synchronization
You can synchronize user accounts across multiple managed endpoints. When account
synchronization is enabled, a change made to a user profile in the Provisioning Server is
propagated to all of the endpoints where that user has an account.
Note: You specify account synchronization settings on the Profile tab for a CA Identity
Manager task. For more information about configuring account synchronization, see the
Administration Guide.
Chapter 4: Planning Your Implementation 45
Decide What to Manage
Account Templates
Account templates define how a user is represented in a managed endpoint. For
example, a template for an Exchange account could define the format of a user’s email
address, such as <first initial><last name>@mycompany.com.
Account templates also determine the privileges a user has within a managed system.
For example, in addition to defining the format of an email address, a template for an
Exchange account may also limit a user’s mailbox size.
You create and manage account templates in the User Console.
Explore and Correlate Functionality
The Explore and Correlate features simplify endpoint management by discovering and
synchronizing changes in managed sytems.
The Explore feature finds objects, including accounts, in endpoints, and stores
references to them in the Provisioning Directory. You can use the Explore feature to
detect any new objects to be managed. For example, if you provision accounts in an
LDAP directory and new organizations are added in that directory, you can use the
Explore feature to introduce those new organizations for use in account templates.
The Correlate feature associates an account in a managed endpoint with a global user in
the Provisioning Directory. When a change is made to the account through the
endpoint, the Correlate feature can synchronize those changes with the global user
account.
Note: For more information about the Explore and Correlate functionality, see the
Administration Guide.
How to Configure Support for Provisioning
After deciding to implement provisioning, you complete the following high-level steps.
1.
Use the CA Identity Manager Server installer to install the CA Identity Manager
Server, the Provisioning Server, the Provisioning Directory Initialization, and the
Administrative Tools.
Note: For more information about installing CA Identity Manager components, see
the Installation Guide.
2.
46 Implementation Guide
Configure the Provisioning Manager to connect to the CA Identity Manager Server.
Determine Audit Requirements
3.
Configure Provisioning in the CA Identity Manager Management Console:
a.
Enable Provisioning.
b.
Configure an environment for Provisioning by completing the following:
–
Importing custom role definitions
–
Configuring an inbound administrator
–
Connecting the environment to the Provisioning Server.
Note: For more information, see the Configuration Guide.
4.
Create endpoints in the User Console.
This allows CA Identity Manager to manage the endpoint.
Note: For more information about endpoint management, see the Administration
Guide.
5.
Explore and correlate the endpoint.
When you explore an endpoint, CA Identity Manager finds the objects in the
endpoint and stores instances of them in the provisioning directory. This action
populates the provisioning directory with accounts and other objects found in the
endpoint.
When you correlate accounts on an endpoint, CA Identity Manager associates them
with a global user in the provisioning directory. You may choose whether the
correlate function creates any global users that are not present or whether it
associates accounts with no matching global user to the [default user] global user.
6.
Create and maintain endpoint accounts by using account templates, which contain
the attributes that are used to create accounts.
7.
Associate the account templates with provisioning roles.
When you assign provisioning roles to users, CA Identity Manager creates accounts
in the associated endpoints for those users.
Note: For information about account templates and provisioning roles, see the
Administration Guide.
Determine Audit Requirements
CA Identity Manager includes auditing capabilities that allow you to monitor activities in
a CA Identity Manager environment.
This information is stored in an audit database. The amount and type of information
that is stored in the audit database is configurable.
Chapter 4: Planning Your Implementation 47
Determine Audit Requirements
You view audit data in the User Console through a task called View Submitted Tasks.
This task allows administrators to search for and view tasks that occur in the system.
Administrators can view task information at a high level or view task and event details.
CA Identity Manager Auditing Considerations
Audit data provides a historical record of operations that occur in a CA Identity Manager
environment. To audit data in CA Identity Manager, you need the following:
■
An auditing database
■
An audit settings file
Audit Database
When you use the CA Identity Manager Installer, CA Identity Manager configures a
connection to a single database, called the CA Identity Manager Database, and creates a
data source to connect to the database tables for auditing.
Note: The CA Identity Manager Database also includes data that is used by other CA
Identity Manager functionality, including task persistence, workflow, and reporting. For
scalability purposes, you can create a new, separate instance of a database for auditing.
Note: For more information about the auditing database, see the Installation Guide.
Audit Settings
You configure audit settings in an audit settings file. An audit settings file determines
the amount and type of information that CA Identity Manager audits. You can configure
an audit settings file to do the following:
■
Enable auditing for a CA Identity Manager environment.
■
Enable auditing for some or all of the CA Identity Manager events generated by
admin tasks.
■
Record event information at specific states, such as when an event completes or is
cancelled.
■
Log information about attributes involved in an event. For example, you can log
attributes that change during a ModifyUserEvent event.
■
Set the audit level for attribute logging.
Note: For more information about configuring auditing, see the Configuration Guide.
48 Implementation Guide
Decide User Store Requirements
CA Audit Considerations
CA Audit is an audit management system that enables you to collect and store security
related data for auditing, reporting, compliance verification and event monitoring.
To integrate with CA Audit, you install the iRecorder component when you install the CA
Identity Manager Server. The iRecorder retrieves events from CA Identity Manager.
Based on policies in the CA Audit Policy Manager, the iRecorder ignores the event or
routes it through to CA Audit.
Decide User Store Requirements
A CA Identity Manager implementation must include a user store that contains the user
identities that CA Identity Manager maintains. Typically, this is an existing user store
that an enterprise uses to store information about its users, such as employees and
customers.
If your implementation includes provisioning, CA Identity Manager also requires a
provisioning directory that includes global users, which are associated with accounts on
endpoints such as Microsoft Exchange, Active Directory, and Oracle.
Managing Multiple User Stores
An enterprise may maintain multiple user stores. In each user store, the user identity
allows access to different corporate resources. You can use one of the following
methods to manage multiple user stores:
■
Use CA Identity Manager to directly manage the Provisioning Directory and use the
Provisioning Server to indirectly manage the users and accounts in the different
user stores.
This approach allows you to:
–
Centrally manage users who can be assigned various enterprise resources from
one location
–
Implement common security and business rules across enterprise resources.
This may include the following:
■
Role-based access control
■
Delegated administration
■
Tasks and screens that are customized based on the type of corporate
identities they manage

Decide Hardware Requirements
The hardware that you need for a CA Identity Manager installation depends on the
functionality that you want to implement and the size of your deployment.
The following sections describe typical CA Identity Manager implementations and their
required hardware.
Chapter 4: Planning Your Implementation 51
Decide Hardware Requirements
Deployment Types
When planning the hardware needed for a CA Identity Manager deployment, consider
the features that you want to implement and the initial size of the deployment. Use one
of the following categories to estimate the size of the deployment.
Note: The deployment type you select determines the size of the DxGrid file that is used
by the Provisioning Directory. You specify the deployment type when you install the CA
Identity Manager Server.
Demonstration
A single server deployment for use in demonstrations or basic testing in a
Development environment. A demonstration deployment supports up to 10,000
provisioned accounts.
Note: This implementation type does not support production implementations.
Basic
A high availability implementation that is suitable for most small to medium size
implementations. A basic implementation supports up to 400,000 provisioned
accounts.
This type of implementation requires two servers for running the CA Identity
Manager application and its components and two servers for running the CA
Identity Manager database and the user store.
Intermediate
A high availability implementation that is suitable for medium size
implementations. An intermediate deployment supports up to 600,000 provisioned
accounts.
Large Enterprise
A high availability implementation that includes additional server clusters to
address additional users and an increased number of transactions. A large
deployment supports more than 600,000 provisioned accounts.
Note: For more information about high availability implementations, see the Installation
Guide.
52 Implementation Guide
Decide Hardware Requirements
Additional Requirements for Provisioning
In addition to the components required for a basic CA Identity Manager
implementation, the following additional components are required when CA Identity
Manager includes provisioning:
■
Provisioning Server
Can be installed on the same machine as the CA Identity Manager server.
■
Provisioning Directory Initialization
Important! The Provisioning Directory Initialization must be installed on CA
Directory.
■
Provisioning Manager
Can be installed on any Windows machine that can access the Provisioning Server.
Note: In a development environment, these components can be installed on one
machine that also includes the basic installation components.
Additional Requirements for SiteMinder Integration
When CA Identity Manager integrates with SiteMinder, the implementation must
include the components in the basic CA Identity Manager installation, plus the following
additional components:
■
Policy Server
Provides policy management, authentication, authorization, and accounting
services.
The Policy Server can be installed on the same machine as the CA Identity Manager
Server, if the Policy Server is dedicated to CA Identity Manager. If the Policy Server
is protecting other applications, we recommend installing it on a separate machine
to ensure best performance.
■
Policy Store
Contains all of the Policy Server data. You can configure a policy store in a
supported LDAP or relational database. In high availability implementations, we
recommend installing the policy store on a separate server.
■
Extensions to the Policy Server
Enables a SiteMinder Policy Server to support CA Identity Manager. Install the
extensions on each SiteMinder Policy Server system in your CA Identity Manager
implementation.
■
SiteMinder Web Agent
Works with the SiteMinder Policy Server to protect the User Console. Installed on
the system with the CA Identity Manager Server.

Choose a Method to Import Users
Choose a Method to Import Users
If you need to import users into an existing user store, the method you select should be
based on your business requirements.
The following sections describe options for importing users.
How to Import Users into a New User Store
After you decide how to store user data, you may need to import users from one store
to another. Depending on your implementation, you can use different methods to
import users.
Note: After importing users into a new user store, you can use identity policies (see
page 55) to apply changes to imported users.
Import Users Through CA Identity Manager
CA Identity Manager provides the following methods for adding users to a user store
that it manages directly.
Method
Features
Limitations
Bulk Loader
Allows you to use the Bulk
Loader task in the User Console
to upload feeder files that are
used to manipulate large
numbers of managed objects
simultaneously.
If you are using the Bulk Loader,
you may see out-of-memory
exceptions depending on the
number of users you are
importing.
The advantage of the Bulk
Loader method is that you can
automate the process of
manipulating a large number of
managed objects using an
information (feeder) file. The
Bulk Loader task can also be
mapped to a workflow process.
Remote Task

Execute Identity Policies on Imported Users
An identity policy is a set of business changes that occur when a user meets a certain
condition or rule. These changes can include assigning or revoking roles (including
provisioning roles for users in the provisioning directory), assigning or revoking group
membership, and updating attributes in a user profile.
You can use identity policies to apply changes to user accounts after they have been
imported to a new user store.
This section describes methods for executing identity policies for imported users in one
or two steps.
One-Step Approach
You can use the following import methods to execute identity policies on users that you
import into a new user store in a single step:
■
Bulk Loader in the User Console
■
Create User Task Execution via TEWS
■
Inbound Synchronization
Two-Step Approach
Using a two step approach, you first import users and then execute identity policies
against the those users. You can use this method when CA Identity Manager manages
users in the Provisioning Server. This method may provide more flexibility, depending on
your import requirements.
1.
Use one of the import tools for adding users into the Provisioning Directory.
2.
Invoke the CA Identity Manager Synchronize User Task through TEWS on each of
the imported users.

Develop a Deployment Plan
Synchronize Global Users with the CA Identity Manager User Store
After you import users into the Provisioning Server, you can use the following methods
to add those users to the CA Identity Manager user store:
■
Inbound Synchronization
Inbound Synchronization keeps CA Identity Manager users up to date with changes
that occur in the Provisioning Directory. Changes in the Provisioning Directory
include those made using Provisioning Manager or systems with connectors to the
Provisioning Server.
Note the following when using inbound synchronization to import users:
–
In the CA Identity Manager Management Console, you can customize how the
attributes from the inbound request are mapped to attributes in the CA
Identity Manager task.
Note: For more information, see the Administration Guide.
–
■
Consider which Provisioning Server changes require synchronization with the
corporate user store. Synchronizing a large number of changes may impact
performance and scalability.
Provisioning Roles and Account Templates
The Provisioning Server can manage accounts in the CA Identity Manager user store
using provisioning roles and account templates. This requires that a managed
endpoint, which points to the CA Identity Manager user store has been acquired
and the appropriate account templates and roles exist. In this case, global users
created through one of the options described in Import Users Through the
Provisioning Server can be assigned a provisioning role that creates the user
account in the CA Identity Manager user store.
Develop a Deployment Plan
When planning a large implementation, you should deploy CA Identity Manager
functionality in stages. The following deployment order allows you to gain significant
value from CA Identity Manager quickly, evaluate the changing needs of your
implementation over time, and carefully construct your environment for best
performance and scalability:
■
Self-service and password management
■
Identity policies
■
Workflow approvals
Chapter 4: Planning Your Implementation 57
Develop a Deployment Plan
■
Delegated administration for user, group, and organization objects
■
Delegated administration for role administration
After each deployment stage, be sure to evaluate performance and make adjustments
before proceeding to the next stage. Optimizing CA Identity Manager (see page 65)
provides information on performance, tuning, and scalability.
Deploy Self-Service and Password Management
Deploy self-service tasks and password management before deploying other CA Identity
Manager features for the following reasons:
■
Self-service tasks and password management are easy to deploy and provide
significant value quickly.
■
These features are independent of the delegated administration model and can be
reconfigured as needed to address changing business needs.
■
These features typically generate the highest volume of tasks that CA Identity
Manager processes on a regular basis. Because of this, they provide a way to test
the scalabilty of your implementation before you deploy additional features.
To deploy self-service tasks, you complete the following steps:
1.
Configure the self-registration task.
This is a public task, which is enabled by default during installation. To configure
this task, you add or remove fields from the default self-registration task, as
needed.
2.
Deploy the Self Manager role.
The member rule for this role should be configured to apply to all users, or should
include a member rule that automatically assigns the role to new users. For
example, you can create a member rule that assigns the Self Manager role to all
full-time employees. When a user self-registers, CA Identity Manager can set the
employee type to full-time (by using a logical attribute handler, or business task
handler). The user meets the criteria in the member rule and receives the Self
Manager role automatically.
Note: When you configure member rules for the Self Manager role, do not allow
administrators to add or remove role members. Since the role is assigned
automatically, there is no need for an administrator to explicitly assign the role.
58 Implementation Guide
Develop a Deployment Plan
To deploy password management capabilities, you complete the following steps:
1.
Configure the public password management tasks, such as the Forgotten Password
task.
2.
Create password policies that determine how passwords are created and when they
expire.
3.
Deploy the Password Manager role, which enables role members to reset user
passwords.
Note: For information on roles, tasks, and password management, see the
Administration Guide.
Deploy Identity Policies
An identity policy is a set of business changes that occurs when a user meets a certain
condition or rule. You can use identity policies to provide business-driven entitlements
before a complete delegation model is deployed. For example, you can create an
identity policy that assigns the Sales Manager provisioning role, which grants access to
sales applications, to all users whose title is Sales Manager. When a sales representative
is promoted to Sales Manager, he automatically receives access to all of the systems he
needs to do his job without waiting for administrator involvement.
To deploy identity policies, you complete the following steps:
1.
Configure identity policies that are triggered by changes to user profile attributes.
2.
Configure the User Manager role to allow a small number of administrators to use
user tasks, such as Create User and Modify User, to change the attributes that
trigger the identity policies.
Be sure to configure the scope rules in the User Manager member policies to
determine the set of users that role members can manage.
Chapter 4: Planning Your Implementation 59
Develop a Deployment Plan
Note the following when deploying identity policies:
■
Consider initially creating identity policies that grant entitlements that do not
require workflow approvals. This allows you to deploy identity policies without
having to define workflow processes, approval forms, and approver models.
■
Before creating identity policies, you should be familiar with other methods of
implementing business rules in CA Identity Manager, such as data validation rules,
logical attributes, business logic task handlers, and workflow processes, to
determine which method provides the best solution.
Note: For more information about these methods, see the Administration Guide
and the Programming Guide for Java.
■
Identity policies are an efficient way to assign entitlements in CA Identity Manager,
however, they may significantly impact performance (see page 80).
■
For the initial deployment of user tasks, consider removing or hiding relationship
tabs, such as Roles tabs, that manage the same entitlements as identity policies.
This prevents the risk of unauthorized entitlements and prevents the potential
performance impact of improperly constructed roles.
Note: For more information about identity policies, see the Administration Guide.
Deploy Workflow Approvals
Workflow approvals can add an additional level of security and automation to your CA
Identity Manager implementation.
Deploying workflow approvals requires the following tasks:
1.
Decide which events or tasks require approvals.
2.
Define the set of approvers, called participants, for each workflow process.
Note: All participants are determined dynamically by participant resolvers. To
maintain good performance, limit the number of participants to thirty users.
3.
Configure approval forms.
4.
Define custom workflow processes, if needed.
Environment and Task Level Workflow Approvals
CA Identity Manager supports two types of approvals: environment-level approvals and
task-level approvals. Environment-level approvals are defined for all instances of an
event, regardless of the tasks they are associated with. Task-level approvals are defined
for a specific event associated with a specific task. Task-level approvals take precedence
over environment-level approvals.
60 Implementation Guide
Develop a Deployment Plan
Most approvals are defined at the environment level to ensure that the same workflow
activities occur for an event, regardless of the task that it is associated with. However, in
the following situations, consider implementing task-level workflow:
■
You have specialized tasks that execute specific business changes that generate
events, which do not require approvals.
■
You have changes actions, triggered by identity policies, that generate events that
do not require workflow approval.
■
You need the flexibility to associate specific workflow processes with task-specific
changes.
Environment-level approvals may require significant processing and system resources as
the volume of transactions increases. This may eventually introduce performance and
scalability issues. Using task-level approvals, where appropriate, may reduce or
eliminate these issues.
Deploy Delegated Administration for Users, Groups and Organizations
Delegated administration is the management of users and their entitlements by having
different CA Identity Manager users perform the functions of modifying, assigning, and
using a role.
Note: Delegation models must be carefully constructed to ensure good performance
and scalability in your CA Identity Manager implementation.
Delegation is enforced by scope rules, which are defined in member and admin policies
for admin roles. A scope rule determines the objects on which a role member can use
the role. For example, a scope rule may enable a User Manager to manage users in his
department, but not in other departments.
Generally, scope rules should reflect the logical structure of the user store. For example,
in a hierarchical LDAP user store, scope may be defined by organizations. In a relational
database, scope can be defined using attributes such as department ID.
Chapter 4: Planning Your Implementation 61
Develop a Deployment Plan
Note the following when deploying delegated administration for users, groups, and
organizations:
■
Limit access to relationship tabs, such as the Admin Roles and Provisioning Roles
tabs, in user-related tasks. These relationship tabs are included in default user
tasks, such as Create User and Modify User. Consider removing them from the
default tasks and using them only in specialized tasks which are associated with a
small number of admin roles.
■
CA Identity Manager evaluates each scope rule dynamically; scope information is
not cached. Consider creating scope rules that contain simple directory queries to
ensure good performance.
■
Evaluate the performance of scope rules by determining how long it takes CA
Identity Manager to return the objects an administrator can manage.
Deploy Delegated Administration for Roles
Delegated administration of roles grants the most significant privileges in CA Identity
Manager and can have the greatest affect (see page 66) on performance. For these
reasons, you should consider deploying delegated administration for roles after you
have deployed all other functionality.
When deploying delegated administration for roles, note the following:
62 Implementation Guide
■
Limit the number of admin roles, admin role members, and admin role
administrators to protect the environment and ensure good performance.
■
Once you deploy delegated administration for roles, conduct performance and
scalability tests. Optimize the environment as needed.
Chapter 5: Integrating with SiteMinder
This section contains the following topics:
CA SiteMinder® and CA Identity Manager (see page 63)
SiteMinder Authentication (see page 64)
CA SiteMinder® and CA Identity Manager
When CA Identity Manager integrates with CA CA SiteMinder®, CA CA SiteMinder® can
add the following functionality to a CA Identity Manager environment:
Advanced Authentication
CA Identity Manager includes native authentication for CA Identity Manager
Environments by default. CA Identity Manager administrators enter a valid
username and password to log in to a CA Identity Manager Environment. CA
Identity Manager authenticates the name and password against the user store that
CA Identity Manager manages.
When CA Identity Manager integrates with CA CA SiteMinder®, CA Identity Manager
uses CA CA SiteMinder® basic authentication to protect the Environment. When
you create a CA Identity Manager Environment, a policy domain and an
authentication scheme are created in CA CA SiteMinder® to protect that
Environment.
When CA Identity Manager integrates with CA CA SiteMinder®, you can also use CA
SiteMinder® authentication to protect the Management Console.
Access Roles and Tasks
Access roles enable CA Identity Manager administrators to assign privileges in
applications that CA CA SiteMinder® protects. Access roles represent a single action
that a user can perform in a business application, such as generating a purchase
order in a finance application.
Directory Mapping
An administrator can possibly need to manage users whose profiles exist in a
different user store from the one that is used for authenticating the administrator.
When logging in to the CA Identity Manager Environment, the administrator is
authenticated using one directory and a different directory to authorize the
administrator to manage users.
When CA Identity Manager integrates with CA CA SiteMinder®, you can configure a
CA Identity Manager Environment to use different directories for authentication
and authorization.
Chapter 5: Integrating with SiteMinder 63
SiteMinder Authentication
Skins for Different Sets of Users
A skin changes the look of the User Console. When CA Identity Manager integrates
with CA CA SiteMinder®, you can enable different sets of users to see different
skins. To accomplish this change, you use a CA SiteMinder® response to associate a
skin with a set of users. The response is paired with a rule in a policy, which is
associated with a set of users. When the rule fires, it triggers the response to pass
information about the skin to CA Identity Manager, to build the User Console.
Note: For more information, see the User Console Design Guide.
Locale Preferences for a Localized Environment
When CA Identity Manager integrates with CA CA SiteMinder®, you can define
locale preference to a user using an imlanguage HTTP header. In the CA
SiteMinder® Policy Server, you set this header within a CA SiteMinder® response
and specify a user attribute as value of the header. This imlanguage header acts as
the highest priority locale preference for a user.
Note: For more information, see the User Console Design Guide.
More Information:
Installation with SiteMinder Policy Server (see page 41)
SiteMinder Authentication
CA Identity Manager includes the following consoles, which should be protected:
User Console
Enables CA Identity Manager administrators to perform tasks in a CA Identity
Manager environment.
Management Console
Enables CA Identity Manager administrators to create and configure a CA Identity
Manager directory, Provisioning Directory, and a CA Identity Manager environment.
CA Identity Manager includes native authentication, which protects the User Console by
default. The Management Console is not protected by default, but you can configure CA
Identity Manager to protect it. CA SiteMinder can also be used for protecting the
Management Console.
To configure other types of authentication for the User Console, such as certificate or
key authentication, CA Identity Manager must integrate with SiteMinder.
Note: For more information, see the Configuration Guide.

This section contains the following topics:
CA Identity Manager Performance (see page 65)
Role Optimizations (see page 66)
Task Optimizations (see page 73)
Guidelines for Group Member/Administrator Optimizations (see page 79)
Identity Policy Optimizations (see page 80)
User Store Tuning (see page 85)
Tuning for Provisioning Components (see page 86)
Runtime Components Tuning (see page 86)
CA Identity Manager Performance
CA Identity Manager performance depends on the individual performance of different
features and components.
You can optimize the following functionality in a CA Identity Manager environment:
■
Roles
■
Tasks
■
Group membership and management
■
Identity policies
For additional performance gains, you can also tune the following components:
■
User store
■
Provisioning components
■
Runtime components, including the databases, such as the task persistence
database, and application server settings
To ensure best performance, configure the CA Identity Manager functionality using the
guidelines in the following sections. Then, measure performance and tune components,
as needed. Because the components work together, it may take several iterations
before you find the best tuning settings for your environment.
Chapter 6: Optimizing CA Identity Manager 65
Role Optimizations
Role Optimizations
CA Identity Manager includes three types of roles:
■
Admin roles
Determine the privileges a user has in the User Console.
When a user logs into a CA Identity Manager environment, the user's account has
one or more admin roles. Each admin role contains tasks, such as Create User, that
a user can complete in that CA Identity Manager environment. The admin roles that
a user has determine the presentation of the User Console, therefore users see only
the tasks that are associated with their roles.
■
Provisioning roles
Give users accounts in managed endpoints, such as an email system.
■
Access roles
Offer an additional way to provide entitlements in CA Identity Manager.
Roles include policies that determine the following:
■
Who can use the role (for admin and access roles only) and where they can use it
■
Who can manage role members and administrators
■
Who can modify the role definition
Evaluating roles and their associated privileges can have a significant impact on CA
Identity Manager performance.
How Role Evaluation Affects Performance at Login
When a CA Identity Manager user attempts to log into the User Console, the following
actions occur:
66 Implementation Guide
1.
CA Identity Manager prompts the user to supply credentials, such as a user name
and password.
2.
The user's credentials are authenticated using one of the following methods:
■
CA Identity Manager native authentication
■
SiteMinder authentication, if the CA Identity Manager implementation includes
SiteMinder
Role Optimizations
3.
CA Identity Manager evaluates every member policy for every admin role in the
environment to determine which admin roles apply to the user.
Note: This evaluation occurs only once for a given user. After the initial evaluation,
CA Identity Manager caches the results. CA Identity Manager uses the cached
information until a change occurs to the user or to the set of member policies,
which causes CA Identity Manager to refresh the information in the cache.
4.
The CA Identity Manager User Console displays the categories that the user can
view based on his roles.
This process occurs for every user that logs into the User Console. If a CA Identity
Manager environment contains a large number of roles, or inefficient member policies,
role membership evaluation can significantly impact performance. In this case, the
initial screen that users see when they log into the User Console may display slowly.
Note: CA Identity Manager does not need to evaluate member policies when a user
accesses a public task to self-register or to request a forgotten password. In these cases,
CA Identity Manager does not need a list of the user's roles because it does not display
the complete User Console.
Role Objects and Performance
To support each role, CA Identity Manager creates a number of objects in the CA
Identity Manager object store (see page 33), depending on the role configuration.
CA Identity Manager creates one base object for each role. In addition to the base
object, CA Identity Manager creates one object for each policy.
Large numbers of role objects may impact the performance of the object store searches
and policy evaluations.
Chapter 6: Optimizing CA Identity Manager 67
Role Optimizations
Object Store Performance
CA Identity Manager stores information that it needs to manage users and entitlements
in an object store. Having a large number of role objects in the object store may cause
the following issues:
■
Searches for managed objects on CA Identity Manager tasks screens may take
longer.
To reduce the impact on searches, index attributes used in searches (see page 85).
■
Role management tasks may execute slowly.
Some examples of role management tasks that are affected by a large object store
include the following:
■
–
A Create Admin Role task is slow because CA Identity Manager must confirm
that the role name is unique in the object store.
–
The Delete Admin Role task must remove all objects created to support the
role and the object cache must be updated.
CA Identity Manager takes a long time to evaluate role policies.
CA Identity Manager caches information in the object store to improve performance.
Optimize Role Policy Evaluation
For each admin role, you can create three types of policies:
■
Member policies
Define a member rule, which determines the users who receive the role, and scope
rules, which determine the objects that role members can manage
■
Admin policies
Define admin rules, scope rules, and administrator privileges for a role
■
Owner policies
Define who can modify a role
To optimize performance when CA Identity Manager evaluates role policies, consider
the following:
68 Implementation Guide
■
Limit the number of admin roles in a CA Identity Manager environment.
■
Follow the guidelines for creating policy rules (see page 69).
■
Tune the user store.
■
Tune the policy store, if CA Identity Manager includes SiteMinder.
Role Optimizations
Guidelines for Policy Rule Creation
One of the key factors in determining the overall performance of role policy evaluations
is the amount of time it takes to evaluate any single policy rule. To improve policy rule
evaluation time, note the following when you create a policy:
■
When possible, limit the number of policy objects that CA Identity Manager creates
and the number of user store searches that it performs by creating policy rules with
complex expressions.
A single rule with a complex expression is more efficient than multiple rules with
simple expressions.
■
When possible, select the most efficient and scalable type of policy rule.
■
Enable the in-memory evaluation option for policy rules.
The in-memory evaluation option significantly reduces policy evaluation time by
retrieving information about a user to be evaluated from the user store and storing
a representation of that user in memory. CA Identity Manager uses the in-memory
representation to compare attribute values against policy rules.
Note: For more information about the in-memory evaluation option, see the
Configuration Guide.

Role Optimizations
Limit Policy Objects and User Store Searches
Each rule in a role policy requires a set of objects in the object store. When CA Identity
Manager evaluates a rule, it loads these objects and performs any required user store
searches.
The following example shows a member policy that includes three member rules. Each
rule includes four scope rules.
70 Implementation Guide
Role Optimizations
In this example, CA Identity Manager creates the objects and performs the user store
searches described in the following table when evaluating and applying the member
policy.
Rule
Policy Objects Potential User

■
Member rule: where (Department =
"Administration")

■
User scope: City = "Boston"

■
Provisioning role scope: Name = "Employee"
■

In this example, CA Identity Manager creates 15 objects and executes 15 directory
searches to determine membership and scope.
To limit the number of policy objects and user store searches that CA Identity Manager
performs, combine rules into complex expressions. The following example specifies the
same entitlements in the first example as one member rule.
Chapter 6: Optimizing CA Identity Manager 71
Role Optimizations
In this example, CA Identity Manager creates only ten policy objects and performs only
five user store searches.

Select Scalable Policy Rule Types
In addition to the number of policy rules, the type of policy rule may also impact
performance. Typically, policy rules are constructed based on how the user store is
structured and how entitlements are determined. For example, you may create policy
rules based on group membership, organization, or user attributes. However, when
there are multiple ways to construct policy rules, consider the performance guidelines in
the following table before deciding which type of rule to construct.

Note: The policy rule types in the following table are listed in order of performance,
beginning with the most efficient rule type.

Task Optimizations
In CA Identity Manager, the tasks that a user sees in the User Console depend on that
user's specific privileges. To display and execute tasks, CA Identity Manager must
perform multiple security evaluations, which may have a significant impact on
performance when applied over all of the users in a CA Identity Manager environment.
CA Identity Manager performs security evaluations when the following actions occur:
■
A user logs into the User Console
In this case, CA Identity Manager must evaluate a user's roles to determine which
tasks that user can access in the User Console.
■
A user invokes a task
When a task is invoked, CA Identity Manager must determine which objects that
user can manage with that task.
Chapter 6: Optimizing CA Identity Manager 73
Task Optimizations
■
A user accesses a relationship tab
A relationship tab is any tab where a user can view or manage a one-to-many
relationship between the task's subject and a set of entitlements. An example of a
relationship tab is the Admin Roles tab, which displays the roles that a user has.
■
A user adds objects on a relationship tab
For example, CA Identity Manager performs additional security checks when a user
adds additional roles to another user on the Admin Roles tab.
Task performance is affected by the following:
■
Task scope, which determines where an administrator can use a task
■
Relationship tabs, which display an object's relationship to other objects
Task Scope Evaluation and Performance
When an administrator uses an admin task that involves searching for a managed
object, such as a user, group, organization, task, or role, CA Identity Manager evaluates
and applies task scope rules. These rules can significantly impact the amount of time CA
Identity Manager takes to display the list of objects to select for the task.
Note: Unlike member, admin, and owner policy evaluations, information about scope
rule evaluations is not stored in a cache.
Task scope is determined by the following:
■
The type of object that the task manages.
■
Scope rules that apply to the admin role that includes the task. Scope rules are
defined in member, owner, and admin policies.
■
Any user-defined search criteria.
For example, consider a Modify User task, which is included in the User Manager role.
The User Manager role has a member policy with a scope rule that allows User
Managers to manage users in the Employees organization. An administrator opens the
Modify User task and enters the search criteria: Last Name starts with A. In this case, the
scope for the Modify User task is all users in the Employees organization whose last
name starts with A.
How CA Identity Manager Renders Relationship Tabs
A relationship tab allows users to view and manage the relationship that a task's subject
has with a set of entitlements. For example, the Provisioning Roles tab shows the
provisioning roles that a user has.
74 Implementation Guide
Task Optimizations
To determine the objects that appear on a relationship tab, CA Identity Manager
performs numerous security evaluations, which can significantly impact performance.
The following example shows the steps that CA Identity Manager takes to render the
Provisioning Roles tab:
1.
An administrator clicks the Provisioning Roles tab in the Modify User task.
2.
CA Identity Manager retrieves the provisioning roles where the selected user is a
member.
3.
If the tab is configured to allow management of role administrators, CA Identity
Manager makes a second call to retrieve the list of provisioning roles where the
selected user is an administrator.
4.
CA Identity Manager evaluates each provisioning role that the user has to see if the
administrator who initiated the task can manage membership for that role.
If the administrator can manage role members, CA Identity Manager displays an
active check box in the Membership column for that role in the list of roles on the
tab.
5.
CA Identity Manager evaluates each provisioning role that the user has to see if the
administrator who initiated the task can manage administrative rights for that role.
If the administrator can manage administrative rights, CA Identity Manager displays
an active check box in the Administrator column for that role in the list of roles on
the tab.
CA Identity Manager must complete steps 2-5 to display the provisioning roles the
user currently has. If the administrator needs to assign a new provisioning role, the
following additional steps are required.
6.
The administrator clicks the Add button to locate new provisioning roles to assign.
7.
CA Identity Manager displays a search screen that the administrator can use to
search for the role to add.
8.
The administrator enters a search filter to find the role to add.
9.
CA Identity Manager returns the list of provisioning roles that meet following
criteria:
■
The roles match the search filter entered by the administrator.
■
The administrator can manage membership for the roles.
■
The user is in the administrative scope of the administrator for the roles.
■
The user does not already have the provisioning roles.
10. CA Identity Manager repeats step 9 to determine the roles where the administrator
can manage administrative privileges.
Chapter 6: Optimizing CA Identity Manager 75
Task Optimizations
Relationship Tabs and Performance
Because of the number of security evaluations CA Identity Manager performs, rendering
a relationship tab can significantly impact performance. The factors that determine
performance vary depending on the type of tab.
For role relationship tabs, the following factors can impact performance:
■
Number of roles where the task's subject is a member
■
Number of roles where the task's subject is an administrator
■
Number of total objects in the system that CA Identity Manager requires to
calculate the subject's roles
■
Number of member/admin policies per role
■
Complexity of the member/admin policy scope rules
■
The ability to maintain cached authorizations for the task invokers to limit the effect
of the security enforcements
To determine group membership and administrative privileges on group relationship
tabs, CA Identity Manager must search all of the groups in the user store. Performance
of these searches depends on the following factors:
76 Implementation Guide
■
Number of group objects in the user store
■
Number of members in any group
■
Performance of the database or directory where the user store exists
Task Optimizations
Task Processing and Performance
Admin tasks include events, actions that CA Identity Manager performs to complete the
task. A task may include multiple events. For example, the Create User task may include
events that create the user's profile, add the user to a group, and assign roles.
When CA Identity Manager processes a task, it processes each event associated with the
task. During event processing, CA Identity Manager saves each event four times. This
allows CA Identity Manager to preserve in-process actions in the event of an unexpected
system shutdown.
When CA Identity Manager processes multiple events at the same time, the events are
added to a queue. When the first event completes the first stage of its lifecycle, it is
saved, and then moved to the back of the queue to wait for the second stage processing
to begin. CA Identity Manager then completes the first processing stage for the next
event in the queue, and that event moves to the end of the queue. The process
continues until all of the events in the queue have completed the first processing stage.
Then, the first event in the queue begins the second processing phase. This continues
until all of the events in the queue complete all four processing stages.
Under normal load conditions, this behavior does not impact performance. However, if
the system is processing a large number of tasks and events, such as during a bulk load
of a large user population, each event and task must wait longer in the queue and,
therefore, has a longer completion time.
To prevent performance issues under load conditions, consider the following actions:
■
Use the Task Priority setting on a task's Profile tab.
The Task Priority setting allows you to set the priority of a task to High, Medium, or
Low.
Tasks that need to be processed immediately should be set to High. Tasks involved
in a bulk load should be set to Low.
If a task priority is set, the events associated with the task are processed with other
tasks that have the same priority. For example, if the Modify User task is set to High
priority, and an administrator modifies a user profile, CA Identity Manager
processes that task before tasks with Medium or Low priority. If there are other
High priority tasks, CA Identity Manager completes the first processing stage for the
first High priority event and then moves that event to the end of the list of other
High priority events.
■
Install a separate, dedicated CA Identity Manager Server to handle bulk load
operations
Chapter 6: Optimizing CA Identity Manager 77
Task Optimizations
Guidelines for Optimizing Tasks
The default tasks, which CA Identity Manager deploys when you create a CA Identity
Manager environment, are configured to support a wide range of administration use
cases. Most CA Identity Manager implementations do not require all of the functionality
provided in the default tasks. After creating a CA Identity Manager environment, modify
these tasks to suit specific administration needs.
The following steps provide guidelines for modifying tasks:
■
Create specialized user management tasks
The default Create User, Modify User, and View User tasks provide full
administrative capabilities. In most implementations, only a small number of
administrators need all of the available capabilities.
Create new tasks that include only the required capabilities. For example, if most
user management tasks involve only profile and group management, create a new
Modify User task that includes only the Profile and Group tabs. Remove the Admin
Roles, Access Roles, and Provisioning Roles tabs, which are available in the default
Modify User task.
Unused tabs can cause significant overhead if they are left in frequently used tasks.
This is especially true when using a Task Execution Web Service (TEWS) client,
where these tabs may be inadvertently activated through the tab java class, which
is provided with CA Identity Manager.
The specialized tasks that you create should match the delegated administration
model (see page 62) that you defined for your environment.
■
Disable Manage Administrators in relationship tabs
By default, all relationship tabs provide the ability to manage administrative rights
for the object that the tab manages, such as roles and groups. Most
implementations do not need to provide this functionality to administrators.
To eliminate the additional overhead that occurs when CA Identity Manager
evaluates administrative rights, clear the Manage Administrators option on the
following tabs, if this functionality is not required:
■
Admin Roles
■
Provisioning Roles
■
Access Roles
■
Groups
To enable users to manage administrative rights on specific tabs, create copies of
the default tabs, enable the Manage Administrators option, and disable the Manage
Members option. Add the new tabs to specialized tasks, which are only used by the
administrators who need them.
78 Implementation Guide
Guidelines for Group Member/Administrator Optimizations
■
Enable scoped searches in role relationship tabs
You can configure each role tab to include searches that allow administrators to
specify criteria for new roles to assign to a user. Role searches limit the number of
member and admin policy rules that CA Identity Manager must evaluate to
determine which roles an administrator can assign to a user.
■
Set task synchronization options
For each CA Identity Manager task, you can specify a user synchronization option,
which synchronizes users with identity policies, and a provisioning account
synchronization option, which synchronizes users with provisioned accounts. The
options enable you to synchronize users when a task completes, or when an event
completes.
To eliminate evaluation and processing time, set the synchronization to occur when
a task completes, instead of when events complete.
Guidelines for Group Member/Administrator Optimizations
To improve performance of searches for group members and administrators, consider
the following:
■
Define well-known attributes in the directory configuration file (directory.xml),
which describes the user store structure and contents to CA Identity Manager.
A well-known attribute is an attribute that has a special meaning in CA Identity
Manager.
To improve group member\administrator searches, define the following
well-known attributes for the user object:
%MEMBER_OF%
Identifies an attribute on the user object that stores a list of groups where the
user is a member.
When defined, this attribute can prevent CA Identity Manager from searching
all of the members in all of the groups in the user store. Group searches can
significantly affect performance in very large groups.
%ADMINISTRATOR_OF%
Identifies an attribute on the user object that stores a list of groups where the
user is an administrator.
Like the %MEMBER_OF% attribute, this well-known attribute can eliminate
lengthy group searches.
■
Specify the Group Type in the directory configuration file
CA Identity Manager supports three types of groups: standard groups, nested
groups, and dynamic groups.
Chapter 6: Optimizing CA Identity Manager 79
Identity Policy Optimizations
When you define the group object in the directory configuration file, you can
specify the type of groups that the user store supports. If your implementation does
not support nested or dynamic groups, set the Group Type attribute as follows:
GroupType = NONE
The setting NONE specifies support for standard groups.
The default Group Type setting is ALL, which may impact performance.
Note: For more information about well-known attributes and group types in the
directory configuration file, see the Configuration Guide.
■
Set the Provisioning Directory cache indices to improve GlobalGroup performance
For CA Identity Manager implementations that include a combined user store and
Provisioning Directory, GlobalGroup membership can be optimized for policy rule
evaluation for roles and identity policies.
To enable this optimization, you index the following attributes, which the
Provisioning Server uses to resolve group membership, in the Provisioning Directory
cache:
eTID
The unique object ID attribute. For group membership lookups, the value is a
specific user or group involved in the lookup.
eTPID
The parent ID of the object used when searching for membership relationships.
eTCID
The child ID of the object used when searching for membership relationships.
Additionally, add the following hash entries:
eTSuperiorClass
The type of the parent object in a membership lookup
eTSubordinateClass
The type of the child object in a membership lookup
Note: For more information about the Provisioning Directory cache, see the
Installation Guide.
Identity Policy Optimizations
An identity policy is a set of business changes that occurs when a user meets a certain
condition or rule. These changes can include assigning or revoking roles, assigning or
revoking group membership, and updating attributes in a user profile.
80 Implementation Guide
Identity Policy Optimizations
CA Identity Manager evaluates identity policies when user synchronization occurs.
Identity policy performance is affected by the following:
■
How the identity policies are configured
■
How often user synchronization occurs
How Users and Identity Policies Are Synchronized
When using identity policies, it is important to understand how CA Identity
Manager evaluates and applies the policies to users. Without a thorough
understanding of the user synchronization process, you may configure identity
policy sets that yield unexpected results.
The following procedure describes how CA Identity Manager evaluates and applies
identity policies:
1.
The user synchronization process begins:
■
Automatically—You can configure CA Identity Managertasks to automatically
trigger user synchronization
■
Manually—Use the Synchronize User task in the User Console to synchronize a
user.
2.
CA Identity Manager determines the set of identity policies that apply to a user.
3.
CA Identity Manager compares the set of identity policies that apply to a user with
the list of policies that have already been applied to that user.
Note: The list of policies that have been applied to a user is stored in the
%IDENTITY_POLICY% well-known attribute in the user profile. For information on
configuring this attribute, see the Configuration Guide.
4.
■
If an identity policy is on the list of applicable policies, and the policy has not
been applied to the user previously, then CA Identity Manager adds the policy
to an allocation list.
■
If an identity policy is on the list of applicable policies, the policy has been
previously applied to the user, and the Apply Once setting for the policy is
disabled, CA Identity Manager adds the policy to a reallocation list.
■
An identity policy is not on the list of applicable policies, and the policy has
been applied to the user, the user no longer matches the policy condition. CA
Identity Manager adds these policies to a deallocation list.
After CA Identity Manager evaluates all of the policies for a user, it applies policies
in the following order:
a.
Identity policies from the deallocation list
b.
Identity policies from the allocation list
c.
Identity policies from the reallocation list
Chapter 6: Optimizing CA Identity Manager 81
Identity Policy Optimizations
5.
After the identity policies have been applied, CA Identity Manager reevaluates the
policies to see if any additional changes are needed based on changes that occurred
in the first synchronization process (steps 2-4).
This is to ensure that changes made by applying identity policies did not trigger
other identity policies.
6.
CA Identity Manager continues to reevaluate and apply identity policies until the
user is synchronized with all applicable policies, or until CA Identity Manager
reaches the maximum recursion level, which is defined in the Management
Console.
For example, an identity policy may change a user's department when the user is
assigned a role. The new department triggers another identity policy. However, if
the recursion level is set to 1, the subsequent change is not made until the user is
synchronized again.
For more information about setting the recursion level, see the Management
Console Online Help.
Design Efficient Identity Policies
Use the following guidelines when you create identity policies:
■
Limit the number of policy objects
CA Identity Manager creates objects in the object store that support identity
policies. To reduce the number of objects in the object store, create identity
policies with complex expressions.
A similar approach is recommended for role policies (see page 70).
■
Limit identity policy set iterations
You can configure the recursion level for an identity policy, which determines the
number of times that CA Identity Manager evaluates and applies identity policies
when a user is synchronized. For example, an identity policy may change a user's
department when the user is assigned a role. The new department triggers another
identity policy. However, if the recursion level is set to 1, the subsequent change is
not made until the user is synchronized again.
Setting the recursion level limits the number of times that CA Identity Manager
must evaluate identity policies.
82 Implementation Guide
Identity Policy Optimizations
■
Limit dependencies between identity policy rules
You can create an identity policy where the change action (Action on Apply Policy or
Action on Remove Policy) of one policy is used in the identity policy condition of
another policy as shown in the following table.
Identity Policy
Condition
Action on Apply Policy
where (Job Code =
"100")
Make member of (provisioning Remove member of
role "Account Manager")
(provisioning role "Account
Manager")
Who are members
Make member of (group
of (provisioning role "Account Managers")
"Account Manager")
Action on Remove Policy
Remove member of (group
"Account Managers")
When CA Identity Manager evaluates this type of policy, it must evaluate and apply
changes at least twice to ensure that both conditions are met. The recursion level,
which is set for an entire CA Identity Manager environment, must be greater than 1,
which then causes additional evaluations for each identity policy set.
Limit the Tasks that Trigger User Synchronization
Identity policies are evaluated and applied during the user synchronization process. You
can configure automatic synchronization by specifying one of the following user
synchronization options for a task:
On Task Completion
CA Identity Manager starts the user synchronization process after all of the events
in a task have completed.
On Every Event
CA Identity Manager starts the user synchronization process when each event in a
task completes.
Chapter 6: Optimizing CA Identity Manager 83
Identity Policy Optimizations
For best performance, limit the number of tasks that trigger automatic user
synchronization.
Consider the following when configuring user synchronization:
■
Disable user synchronization for password tasks
In most cases, passwords are not used in identity policy conditions.
■
Disable user synchronization for the Synchronize User task
Since the Synchronize User task triggers identity policy evaluations, CA Identity
Manager performs the evaluations again if the user synchronization option is
enabled for this task.
■
Create specialized tasks
When possible, create tasks that execute modifications that trigger identity policy
conditions and enable user synchronizations for those tasks only.
Optimize Identity Policy Rule Evaluation
To reduce the evaluation time for identity policy conditions that include user-attributes,
you can enable an in-memory evaluation option. When the in-memory evaluation
option is enabled, CA Identity Manager retrieves information about a user to be
evaluated from the user store and stores a representation of that user in memory. CA
Identity Manager uses the in-memory representation to compare attribute values
against policy conditions. This limits the number of calls CA Identity Manager makes
directly to the user store.
Note: For more information about the in-memory evaluation option, see the
Configuration Guide.
84 Implementation Guide
User Store Tuning
User Store Tuning
User store tuning involves a number of steps, including the following:
■
Optimizing the structure of the user store
■
Tuning underlying stores
■
Implementing load balancing and replication
These steps depend on the type of user store that you are using. For tuning information
in these areas, see the documentation for the database or directory that contains the
user store.
In addition to the general tuning considerations, the following tuning considerations are
specific to CA Identity Manager:
■
Measure user store search performance
For optimum performance, CA Identity Manager policy evaluation searches should
complete within 10-20 milliseconds.
To ensure that CA Identity Manager can consistently complete these searches in the
recommended time, consider testing search performance under multiple load
conditions.
You can also use this measurement to determine when a user store reaches its
physical limits and additional servers are required for load balancing.
■
Index attributes
Index each attribute that is used in a role policy or identity policy. Indexing
attributes can provide significant performance improvements.
Note: For information about indexing attributes, see the documentation for the
LDAP directory or relational database that contains the user store.
■
Cache LDAP Binds
In CA Identity Manager, all directory LDAP binds are executed by the proxy user
defined on the CA Identity Manager Directory object. For each connection, the
same LDAP bind occurs for this same user repeatedly.
If you are using an LDAP directory as a user store, configure the directory to cache
LDAP binds (or sessions), if the directory supports it.
■
Enable user store caches
When CA Identity Manager evaluates the policy decisions for a user, that
information is stored in an authorization cache. When the cached information
expires, CA Identity Manager evaluates all policies for that user again.
To improve performance of user store searches in subsequent policy rule
evaluations, enable the user store to cache searched data, if your user store
supports it.
Chapter 6: Optimizing CA Identity Manager 85
Tuning for Provisioning Components
CA Directory includes a cache, called dxCache, which is an in-memory database
implementation that can search across cached data.
Note: For more information about CA Directory, see the CA Directory Administrator
Guide.
Tuning for Provisioning Components
When a CA Identity Manager implementation includes provisioning, use the following
optimizations to ensure the best performance:
■
Optimize the connection between the CA Identity Manager Server and the
Provisioning Server
CA Identity Manager communicates with the Provisioning Server using the Java IAM
(JIAM) API. To improve communication performance, you configure the following:
–
JIAM session pool for multiple connections to the Provisioning Server
Note: CA recommends setting the initial sessions value to 8, and the maximum
sessions to 128.
–
JIAM cache for objects retrieved from the Provisioning Server
Note: For information on JIAM configuration settings, see the Administration Guide.
■
Set account synchronization to occur at the end of a task (see page 78), instead of
the end of each event
■
Tune the Provisioning Server
Note: See the Administration Guide and Installation Guide for more information.
Runtime Components Tuning
Business changes in CA Identity Manager are accomplished through tasks. A task
includes one or more events, which represent activities that CA Identity Manager
performs to complete the task. For example, a Create User task may include the
CreateUserEvent and the AddToGroupEvent.
CA Identity Manager includes the following components, which process tasks and
events at runtime:
86 Implementation Guide
■
CA Identity Manager databases, which support CA Identity Manager functionality
■
JMS messages, which are responsible for processing events
Runtime Components Tuning
Tuning CA Identity Manager Databases
When executing tasks, CA Identity Manager uses the following databases:
■
Task persistence
Maintains information about CA Identity Manager tasks and events over time. This
allows CA Identity Manager to restore the last known state of events and tasks in
the case of system failure.
Note: This database has the most significant impact on CA Identity Manager
performance because the task and its events are saved and retrieved from the
database during state transitions.
■
Audit
Provides a historical record of operations that occur in a CA Identity Manager
environment.
■
Workflow
Stores workflow process definitions, jobs, scripts, and other data required by the
workflow engine.
■
Reporting
Stores snapshot data, which reflects the current state of objects in CA Identity
Manager at the time the snapshot is taken.
CA Identity Manager communicates with each database through a JDBC connection
pool. You create and configure a JDBC connection pool in the application server that
hosts CA Identity Manager. When you configure the JDBC connection pool, note the
following:
■
Consider the number of concurrent tasks that will execute at any one time.
■
Consider the other runtime components when you configure the JDBC connection
pool size. Each runtime component works in conjunction with the other runtime
components.
Note: CA recommends setting the initial connection pool value to 128.
■
For the task persistence database, the number of database connections in the pool
must allow each executing task to retrieve and update task and event data
throughout the lifetime of the task.
■
The task persistence database uses prepared statements. Be sure to configure the
prepared statement cache for the database that you are using to store task
persistence data.
Note: See the documentation for the database that you are using for task
persistence for information on configuring the prepared statement cache.
Chapter 6: Optimizing CA Identity Manager 87
Runtime Components Tuning
JMS Settings
A CA Identity Manager task includes events, actions that CA Identity Manager performs
to complete a task.
During an event's life cycle, it transitions through the following states:
■
BEGIN
■
APPROVED
■
EXECUTING
■
COMPLETED
■
INVALID
Workflow controlled events can also have such states as the following:
■
PENDING
■
REJECTED
CA Identity Manager uses JMS messages to control these state transitions.
How JMS Messages Drive Event Transitions
CA Identity Manager uses JMS messages to drive an event’s state transitions. The
following procedure describes the steps involved:
1.
A user submits a task.
2.
The task generates one or more events.
3.
When an event is ready for processing, CA Identity Manager sets the event's state
to BEGIN and the event is persisted in the task persistence database.
4.
CA Identity Manager creates a JMS message containing the event ID and posts that
message to the Event Message Queue.
5.
Upon receiving the message, JMS then invokes an instance of the Event Message
Driven Bean, which is an implementation of the Event Controller.
6.
The Event Controller uses the event ID in the message to retrieve the event from
the task persistence database, and executes the actions for the event’s current
state.
7.
Upon completion of that state, the event is set to the next state, persisted in the
task persistence database, and a new JMS message is posted for processing the
next state.
This cycle continues until the event has completed its state machine.
88 Implementation Guide
Runtime Components Tuning
JMS Messages and Performance
For any event, there are three to five states that require JMS messages for state
transition:
■
BEGIN
■
PENDING
■
APPROVED or REJECTED
■
EXECUTING
■
COMPLETED or INVALID
(only under Workflow control)
To process a single event, the following actions take place:
■
Three to five posts to the Events Message Queue
■
Three to five invocations of the Message Driven Bean
■
Six to ten connections to the task persistence database (one read action and one
write action per state)
These actions may impact the amount of time it takes CA Identity Manager to process a
task.
To ensure best performance during state transitions, tune the JMS resources in the
application server that hosts CA Identity Manager so that adequate JMS resources are
available.
Tuning JMS Settings
The following application server JMS tuning parameters define Queue connections and
Message Driven Bean instance pools.
■
WebSphere JMS Tuning
WebSphere provides Queue Connection Factories two parameters that you can
configure to improve performance. Use the WebSphere Administration Console to
set the following properties:
–
Under Resources, locate the following Queue Connection Factories:
iam-im-neteQCF and iam-im-wpConnectionFactory.
–
For each one, edit the connection pool properties to set the maximum
connections to 128.

WebLogic Tuning
In WebLogic application servers, Queue Connection Factories obtain
connection-handling threads from the server's JMS Thread Pool or the default
execute pool, depending on the JMS Thread Pool size. If the JMS Thread Pool size is
0, then WebLogic uses the threads in the execute pool.
We recommend setting the number of JMS Thread Pool threads equal to the
maximum Bean Pool size for the CA Identity Manager Event Message Driven Bean,
which is set to 128 by default.
You use the WebLogic Server Console to set the JMS Thread Pool size in the JMS
Services properties for the domain and server where CA Identity Manager is
installed.
The CA Identity Manager Event Message Driven Bean pool size is set by modifying
the max-beans-in-free-pool setting in the descriptor file in the following location:
WebLogic_home\domain\applications\iam_im.ear\identityminder_ejb.jar\META-IN
F\weblogic-ejb-jar.xml
<weblogic-enterprise-bean>
<ejb-name>SubscriberMessageEJB</ejb-name>

■
JBoss Tuning
In JBoss application servers, Queue Connection Factories obtain
connection-handling threads from the server’s Standard JMS Pool session factory.
By default, the number of maximum threads is set to 15.
We recommend setting this value to match the maximum size value of the Standard
Message Bean Container.
90 Implementation Guide

The JMS Session Pool section factory is set in the MaximumSize element of the
JMSContainerInvoker in the following file:

Tuning JBoss 5 Performance
In a default installation of JBoss 5, the JBoss hot deployment scanner runs every 5
seconds, which affects JBoss performance. You can disable this feature, if it is not
needed, or change how often it runs.
To disable or modify hot deployment
1.
Edit the hdscanner-jboss-beans.xml in this location:
Single Node: jboss_home/server/default/deploy
Cluster: jboss_home/server/all/deploy
2.
To disable this feature, add the following line inside the HDScanner bean:
<attribute name="ScanEnabled">False</attribute>
3.
To modify the scan frequency, increase the scanPeriod attribute value above 5000
(milliseconds).
Note: For more details, see this link:

Loss of Service from a Disaster
In the event of a disaster, users can lose access to services that are critical to their jobs.
As a result, these users cannot provide services to other users.
The urgency to restore access to services depends on the actual use of CA Identity
Manager. In some organizations, users require uninterrupted access to services
provided by CA Identity Manager while other users require system restoration within a
day. In either case, we recommend that you make preparations to protect your CA
Identity Manager implementation from an event that causes partial or complete loss of
your systems.
By configuring a redundant architecture for CA Identity Manager, you can ensure that
services are highly available to users. When a primary component fails, the alternate
component continues to provide the same service. In addition, you can routinely back
up critical systems and software, so you can restore any system or data that is
completely lost.
This document provides general planning guidelines for these scenarios. We
recommend that you use these guidelines to develop specific disaster recovery
procedures that address your organization's requirements.
Chapter 7: Creating a Disaster Recovery Plan 93
How to Plan for Disaster Recovery
How to Plan for Disaster Recovery
To develop an effective disaster recovery plan, you engage in the following phases,
which are detailed in this chapter.
Phase
1. Define Disaster Recovery Requirements (see page 95)
Based on your organizational needs, identify what types of disaster to
anticipate and how quickly you would need to restore services.
2. Design a Redundant Architecture (see page 95)
According to your requirements, design an architecture with redundant
components at a remote location.
3. Develop Backup Plans (see page 97)
To protect your installation, develop plans for backing up components.
4. Develop Restore Procedures (see page 99)
Develop procedures for restoring lost components.
5. Document the Recovery Plan (see page 101)
Document your plans for recovering CA Identity Manager from a disaster.
6. Test the Recovery Plan (see page 102)
Based on your disaster recovery procedures, verify that you can reinstate
your CA Identity Manager implementation as it existed before the event.
7. Provide Disaster Recovery Training (see page 103)
Complete the effort by making sure that the people responsible to recover
systems from a disaster are trained to do so.
94 Implementation Guide
Define Disaster Recovery Requirements
Define Disaster Recovery Requirements
The following are some general guidelines to consider for defining requirements for a
disaster recovery plan:
1.
Assemble a team with the following knowledge:
■
Knowledge of the architecture and systems that support CA Identity Manager
■
Knowledge of how to back up the relational databases and LDAP user stores
used by CA Identity Manager
2.
Identify potential disaster scenarios to address, including partial or complete loss of
systems at one or more sites.
3.
List the systems that are critical to be available to support your installation.
4.
Define the acceptable maximum downtime for each of these systems.
For example, systems that support an alternate server may have a lower priority for
restoration.
Design a Redundant Architecture
To protect against failure of a critical component, consider the following protective
actions using alternate components (servers and directories) and redundant databases
at remote locations.
Configure redundancy for CA Identity Manager, using the Installation Guide. Include the
following components:
■
Redundant CA Identity Manager application server nodes as part of a cluster
■
A Policy Server cluster provides failover (if you are using CA SiteMinder to protect
CA Identity Manager)
■
Alternate Provisioning Servers, Provisioning Directories, and connector servers. If a
primary component is lost, the system switches over to the alternate component.
Configure redundancy for databases including the following:
■
Any of the runtime databases that are part of CA Identity Manager such as the
workflow or audit database.
See the documentation supplied with ORACLE or Microsoft SQL Server.
■
The Business Objects database if you are using the Report Server.
See the Business Objects Enterprise, Release 2 and Release 2 SP 4 documentation
on the SAP documentation web site.
Chapter 7: Creating a Disaster Recovery Plan 95
Design a Redundant Architecture
Alternate CA Identity Manager Servers
Providing redundant Application Server nodes for the CA Identity Manager Server
provides scalability and performance benefits and disaster recovery if individual servers
fail. The most common method of providing failover for an application server is to
create a cluster. The procedures for creating the cluster are covered in the cluster
section of the Installation Guide.
Note: For CA Identity Manager r12.0 and higher releases, an application server cluster is
the only valid method to implement a multi-node deployment. CA Identity Manager
environments require the industry standard J2EE cluster architecture, which uses JMS
queues for the backbone. As a result, the only valid method of using multiple nodes in a
CA Identity Manager configuration is an application server cluster.
For more details on this change, see TechDoc 545594.
Alternate Provisioning Components
Several provisioning components have the option of an alternate component to provide
high availability. The alternate component should be at a remote site for the highest
protection.
See the High Availability Provisioning chapter of the Installation Guide for specific
configuration details of alternate servers and directories.
Multi-Site Provisioning Directories
You can create primary and alternate provisioning directories with the alternate
directories at a remote location. CA Directory recommends that you install three
Provisioning Directories, one primary and two alternate directories.
Multi-Site Provisioning Servers
To protect against failure of the primary Provisioning Server, you can configure an
alternate Provisioning Server. The difference between primary and alternate
Provisioning Servers is that the primary server installation populates the Provisioning
Directory container entries. Also, uninstalling a primary server removes those entries.
Apart from installation and uninstallation, the primary and alternate servers function in
the same manner.
96 Implementation Guide
Develop Backup Plans
Multi-Site Connector Servers
For either the Java or C++ Connector Server, you can configure multiple connector
servers to serve the same endpoint or endpoint type.
For each connector server you configure, you should configure an alternate connector
server at a remote location to handle the same endpoints. If the connector server fails,
the alternate server immediately manages the communication with the endpoints.
Redundant Databases
The supported database software, Microsoft SQL Server and Oracle, provide the
capability to provide redundant databases. If the main database fails, the redundant
database is immediately available. The redundant database should be at a remote site in
case the entire site is affected.
Develop Backup Plans
To protect against the loss of any or all systems, use off-site storage for all data that you
back up and a backup schedule that meets your maximum downtime requirements. The
backup and restore procedures use different applications, so they should be
coordinated for recovery of the CA Identity Manager system as a whole.
Include the following components in your backup plans:

Develop Restore Procedures
The restore procedures depend on the backup method. The recovery process for a
failed system depends on the circumstances. However, in many cases, reinstalling the
software is the restore method. See the High Availability Provisioning chapter of the
Installation Guide for details.
Restore the CA Identity Manager User Store
To restore the CA Identity Manager user store, see the documentation supplied with
your database or LDAP software. Verify that the data store from backup is intact
including access to all user stores.
Restore the CA Identity Manager Databases
To restore the CA Identity Manager databases, see the documentation supplied with
your database. Verify that the data store from backup is intact including access to all
databases.
Restore the SiteMinder Policy Store
To restore the SiteMinder policy store, see the documentation supplied with your
database or LDAP software. Verify that the data store from backup is intact including
access to all user stores.
Restore the CA Identity Manager Server
If you lose a cluster node for a CA Identity Manager server, perform the following steps:
1.
Use the standard documented procedure to add a node.
See the Installation Guide chapter on cluster installation.
2.
Update the connection to the Provisioning Server.
See the section on Provisioning failover in the High Availability chapter of the
Installation Guide for details.
Chapter 7: Creating a Disaster Recovery Plan 99
Develop Restore Procedures
Restore a Provisioning Server and Directory
You can restore a lost Provisioning Server by installing an alternate server. If all systems
have failed, restore the data lost during the disaster.
Use the following steps:
1.
Copy any custom schema files to CA Directory config\schema directory.
2.
Install the new Provisioning Directory.
The datastores will be empty.
3.
Restore the data from the backup location.
4.
Use the Provisioning Server installer, providing the details for the newly restored
Provisioning Directory.
The domain information should be there already.
5.
Restore any custom connector and configuration files from backup.
Note: For more detail, see the CA Directory documentation.
Restore Connector Servers
If you lose a connector server, perform the following steps:
1.
Use the Connector Server installer to install a new connector server
Register it with the Provisioning Server during installation.
2.
Remove the registration of the lost connector server using csfconfig or Connector
Xpress.
Restore a Report Server
If you lose the report server, see the Business Objects documentation for the
procedures that apply. On the SAP documentation web site, check for Business Objects
Enterprise, Release 2 and Release 2 SP 4 documentation.
100 Implementation Guide
Document the Recovery Plan
Restore Admin Tasks
If an admin task was in process at the time of disaster, it can be recovered under the
following conditions.
■
Any admin task that was in a Pending state waiting on approvals continues to be
available if the stores used to maintain that state information are preserved. The
stores include the Task Persistence database, the JMS store that holds the task and
event JMS Messages, and the Workflow database.
■
Tasks in the In Progress state (any state other than Pending) are subject to
additional conditions.
A task in this state requires the posting of a new JMS Message to the CA Identity
Manager Event message queue to continue being processed. Outages that occur
before that event being posted to the queue prevent the task from continuing upon
recovery.
In this situation, two options exist to recover the task:
–
If the task is present in the View Submitted Tasks task in the failed state, go to
the task details page and use the Resubmit Task option to resubmit the task.
–
Submit a new task with the same changes.
Document the Recovery Plan
Based on the guidelines in this chapter, we recommend that you develop specific
disaster recovery documentation that applies to your organization.
Consider the following approach:
1.
Identify the names and locations of systems in your architecture and alternate
components for each system.
For each system, list the software installed, such as the specific JDK installed, the fix
release of an application server, and the amount of memory installed. This detail is
necessary for any system that you decide you need to rebuild completely.
2.
Write procedures for recovering each component or for rebuilding a complete
system, if necessary.
3.
Identify a method of locating or resetting usernames and passwords to systems and
CA Identity Manager user interfaces if they are known only to one or two people.
4.
Protect your disaster recovery documentation for loss by creating a backup copy
that you store at a well-known off-site location.
Chapter 7: Creating a Disaster Recovery Plan 101
Test the Recovery Plan
Test the Recovery Plan
To help ensure a successful recovery from a disaster, you can schedule a simulated
disaster, where certain systems become unavailable. Consider the following tests, which
are described in the following sections.
1.
Test the failover process.
2.
Test restoration of systems.
Test the Failover Process
All servers or directories should have an alternate server or directory at a remote site,
including these components:
■
CA Identity Manager server
■
Provisioning Server
■
Provisioning Directories
■
C++ and Java Connector Servers
■
Report Server
■
Policy Server
Manually stop each component and verify that all operations continue to function, using
the alternate component. For example, you could perform the following test of the
Provisioning Server:
1.
On a system with the Primary Provisioning Server, stop the Provisioning Service
services from the Windows services dialog.
The Primary Provisioning Server is stopped.
2.
In the User Console, perform the following actions:
a.
Assign a Provisioning Role to a user.
b.
Verify that the endpoint accounts are created for that user.
The accounts being created depend on the alternate Provisioning Server
handling the communication with the CA Identity Manager server.
This procedure is an example of one test. For each component that you stop, develop
similar tests to verify that the alternate component is in use.
Test the Restore Procedures
According to your disaster recovery documentation, perform a test of each critical
component to confirm that you can restore the lost system.
102 Implementation Guide
Provide Disaster Recovery Training
Provide Disaster Recovery Training
Once you believe that the recovery procedures are reliable, you help ensure that the
people who must implement the recovery are able to do so. Your organization may
require other steps, however, the following are some general guidelines:
1.
Publicize the location of the recovery documentation.
2.
Perform a dry-run of the training.
3.
Incorporate feedback from the training to help ensure the final disaster recovery
procedures are sufficient.
Note: You may also choose to use the training as an opportunity to assign recovery
coordinators, including one person as the recovery coordinator and a second person as
an alternate coordinator. These people should be instructed to meet at a documented
location to begin the disaster recovery plan.
