This can turn SAP deployment and expansion into a lengthy and complex process. In addition, keeping SAP landscapes up to date through patching, updating software, and adding hardware requires a lot of skilled manpower and training. Oracle’s engineered systems for SAP are designed to help savy IT managers deploy more services faster on a streamlined infrastructure that costs less to run. Oracle’s Engineered Systems for SAP For more than 25 years, companies have trusted their business-critical SAP environments to state-of-the art Oracle software. Today, Oracle’s integrated infra structure stack — consisting of servers and storage, operating systems, database software, middleware, networking, and built-in virtualization features — is optimized to deliver agility and performance to SAP applications. Now this integrated stack is available as a family of Engineered Systems that are pre-integra ted, pre-tested, and pre-configured to simplify data center operations, ensure fast and easy SAP infra structure deployment, and accelerate business inno vation. Oracle Exadata Database Machine Designed to deliver extreme performance to data ware housing, OLTP, and mixed-load database applications, the Oracle Exadata Database Machine is ready to perform out of the box. The system is pre-configured with all necessary software—Oracle Database, Oracle Database Real Application Clusters (RAC), Oracle Grid Infrastructure, and storage servers are pre-cab led in racks using Infiniband and Ethernet switches. The complete Oracle Exadata package arrives pre integrated and pre-tested, and can save weeks and sometimes months of time to deployment. Highly optimized for database use and purpose-built for database consolidation, the core of the Oracle Exa data Database Machine is the Oracle Database 11g software and Oracle Exadata Storage Servers and Software. These storage servers overcome the limita tions of conventional storage with a massively-parallel architecture to dramatically increase data bandwidth between the database server and storage. In addition, innovative Exadata technologies, such as Exadata Smart Scan, Exadata Smart Flash Cache, accelerate database processing and speed I/O operations for SAP applications. As the SAP central services (message and enqueue server) and the database can run on the same machine, high availability comes out-of-the-box with the sys tem; the massively scalable, secure, and redundant Oracle Exadata Database Machine is SAP certified and supported, and provides an ideal database-as-a-service platform for SAP applications. Improved application performance, effortless workload management, greater datacenter efficiency, and faster time-to-deployment enable enterprises to make better business decisions in real time and at less cost. O r a c l e ’s E n g i n e e r e d S y s t e m s f o r S A P Oracle Exalogic Elastic Cloud Oracle Exalogic Elastic Cloud is the first engineered system specifically designed to be a foundation for secure, mission-critical, private clouds. Delivering virtually unlimited scalability, unbeatable performance, and previously unimagined management simplicity, the Oracle Exalogic Elastic Cloud is an ideal platform for applications—from small-scale departmental applications to the largest and most demanding SAP applications. Balanced for compute-intensive work loads, each pre-assembled, pre-configured Exalogic system contains fully-integrated, hot-swappable x86 compute nodes, a high-performance ZFS Storage Appliance, and high-bandwidth interconnect fabric and switches. An extremely fast, high-throughput interconnect connects all systems together to create a single large computer with extreme scalability, elasticity, and redundancy. The system exploits the I/O fabric, deli vering performance results that are ten times faster than standard application server configurations. Thousands of applications with differing security, reliability, performance, and service-level requirements can run on a single Exalogic system, making it an ideal platform for SAP applications consolidation. In addition, it forms the foundation of an ideal specialpurpose system when used in combination with an Oracle Exadata Database Machine running Oracle Database. Oracle SPARC SuperCluster SPARC SuperCluster T4-4 combines Oracle inno vation—the computing power of Oracle’s nextgeneration SPARC T4 servers, the performance and scalability of Oracle Solaris 11, the optimized data base performance of Oracle Database 11g and Exadata storage, and the accelerated middleware pro cessing of the Oracle Exalogic Elastic Cloud—into a general-purpose engineered system that provides high availability for enterprise SAP applications. Multiple databases and applications can run on a single system and take advantage of fast improve ments for data compression, queries, OLTP response time, and Java middleware performance. The Oracle SPARC SuperCluster is well suited as an SAP general-purpose system with SAP central in stances, central services and database software installed together on the system. Because the system is pre tested and ready to run, organizations can deploy SAP services in days rather than months. Consolidated SAP applications can run on a mix of Oracle Solaris 10 and Oracle Solaris 11 via Oracle‘s integrated virtualization technologies. In addition, the Oracle SPARC SuperCluster is SAP certified and supported, and is also offered as an Oracle Optimized Solution for SAP that includes deployment best prac tices, ongoing full-stack and patch testing, and more. Oracle Database Appliance The Oracle Database Appliance is a fully redundant, integrated database appliance—software, servers, sto rage, and networking—that offers one-button instal lation, patching, and diagnostics. A complete Oracle RAC database cluster in a box, it ships with Oracle Database Enterprise Edition 11g and Oracle Real Application Clusters al-ready installed to support highly available database services for SAP applicati ons. Maintenance is easy: a single patch handles all firmware and software in one operation, using an Oracle-tested patch engineered specifically for the appliance. With the ability to consolidate databases up to 4 TB in size, it is ideal for midsize companies and departmental systems. Conclusion Built and tuned to run business-critical applications with extreme requirements for network bandwidth, access, and data growth, Oracle’s engineered systems provide a number of options for optimizing SAP infrastructure and improving operation. Deploying one or more Oracle engineered systems within an SAP landscape results in more solid infrastructure, increased performance, greater efficiency and utiliza tion, simplified management through application and database consolidation, and improved total cost of ownership.

The Oracle Exadata Database Machine is an easy to deploy solution for hosting the Oracle Database that delivers the highest available levels of database per formance. The Exadata Database Machine is a “cloud in a box” composed of database servers, Oracle Exadata Storage Servers, an InfiniBand fabric for storage networking and all the other components required to host an Oracle Database. It delivers outs tanding I/O and SQL processing performance for online transaction processing (e.g. SAP ERP 6.0), Business Warehouse (e.g. SAP BW 7.x) and consoli dation of mixed workloads. Extreme performance is delivered for all types of database applications by leveraging a massively parallel grid architecture using Real Application Clusters and Exadata storage. Database Machine and Exadata storage delivers break through performance with linear I/O scalability, is simple to use and manage, and delivers mission-critical availability and reliability. SAP customers can easily migrate their database to Exadata that runs SAP applications unchanged. The migration to Exadata (DB server on either Oracle Linux or Oracle Solaris) is smooth and is not more than a homogeneous or heterogeneous OS platform migration depending on the source platform the database is running on today. The migration can be done either online or offline depending on the source platform and the migration tool (R3Load, RMAN duplicate database, RMAN transportable tablespaces or O2O/Triple-O) as well. For more details see on scn.sap.community/oracle and check Oracle Engine ered Systems”. The advantages of Exadata for SAP customers are obvious since it’s transparent to the application, runs on proven technology such as Oracle 11.2, RAC, etc, eliminates systems integration try-and-error, relies on existing personnel and skills, performs database queries much faster (large and complex Infocubes, queries, or transactions that show a large amount of time spent in the database), less administration time, simpler patching, and greater uptime. Exadata provides High availability and disaster recovery out-of-the-box and highly proven at SAP customers, it helps to consoli date platforms and database, thus reduce power and cooling consumption. Last but not least Oracle Exa data relies on Single vendor, bundled OS and RDBMS patch sets – ends the Multi vendor nightmare. SAP Application with Oracle Exadata Database Machine Presentation Application Database on Exadata SAP Instances SAP ECC 6.0 SAP Instances SAP BW 7.x SAP Instances SAP CRM 7.x The flexible three tier architecture allows for any combination of hardware and operating systems run ning the SAP instances to be used with the Oracle Exadata Database Machine. For instance you can run SAP Application servers on AIX, HP-UX, Linux or any other SAP certified platform against the Oracle Exadata Database Machine. This flexibility allows an easy introduction of the Oracle Exadata Database Machine into existing SAP environments that keeeps SAP layer unchanged. Oracle Exadata Database Machine for SAP Customers Additionally to the database instances running on the database servers, customers can make SAP central services high available on the database nodes through SAPCTL based on Oracle Clusterware, but only if the SAP system is UNICODE. If a separate cluster other than the database cluster is already used for the SAP Central Services then customers can continue to use this separate cluster for the SAP Central Services when deploying the Oracle Exadata Database Machine. Last but not least, BR*Tools are supported to run on Exadata database servers as well. The migration methods of the database are described in the paper “Using SAP NetWeaver with the Oracle Exadata Database Machine: A Best Practices Guide”. See on scn.sap.community/oracle and check Oracle Engineered Systems”. The pure database migration to Exadata actually does not differ from the migration to ASM (Automatic Storage Management file system) already described in detail. The Oracle Exadata Database Machine is an easy to deploy solution for hosting the Oracle Database that delivers the highest levels of database performance available. The Exadata Database Machine is a “cloud in a box” composed of database servers. The Database Machine is a pre-configured system ready to be turned on day one, taking significant integration work, cost and time out of the database deployment process. Since it is a well known configuration Oracle Support is very familiar with how to service the system resulting in a superior support experience with the system. The benefit of a common infrastructure to deploy a database for any application, whether OLTP, OLAP, a mix of the two, or as a platform for consoli dation of several databases, creates tremendous oppor tunities for efficiencies in the datacenter. It is truly a “cloud in box”. 7 8 There are two versions of Exadata Database Machine: • The Oracle Exadata Database Machine X3-2 comes in Eighth, Quarter, Half, and Full Rack configurations to meet any application require ment and to enable you to easily scale as your requirements change. The Full rack comes com plete with eight 2-socket database servers, 14 Oracle Exadata Storage Servers, InfiniBand swit ches and more than 22 terabytes of Exadata Smart Flash Cache to support extremely fast transaction response times and high throughput. See Data Sheet for more details: http://www.oracle.com/us/products/database/ exadata/database-machine-x3-2/overview/index.html • The Exadata Database Machine X3-8 is desig ned for database deployments that require very large amounts of data, delivering extreme perfor mance and scalability for all applications including Online Transaction Processing (e.g. SAP ECC 6.0), Data Warehousing (e.g. SAP BW 7.0 and higher) and consolidation of mixed workloads. It comes complete with two 8-socket database ser vers, 14 Oracle Exadata Storage Servers, InfiniBand switches and more than 22 terabytes of Exadata Smart Flash Cache to support extremely fast trans action response times and high throughput. See Data Sheet for more details: http://www.oracle.com/us/products/database/exadata/ database-machine-x3-8/overview/index.html Exadata Storage Server The Exadata Storage Server runs the Exadata Storage Server Software and provides the unique and power ful Exadata software technology of the Database Machine including Smart Scan, Smart Flash Cache, Smart Flash Logging, IO Resource Manager, Storage Indexes and Hybrid Columnar Compression(not cer tified yet by SAP). The hardware components of the Exadata Storage Server (also referred to as an Exadata cell) were carefully chosen to match the needs of high performance database processing. The Exadata software is optimized to take the best possible advantage of the hardware components and Oracle Database. Each Exadata cell delivers outstanding I/O performance and bandwidth to the database. The CPU cores in the Exadata Storage Server are dedicated to providing features such as Smart Scan SQL processing that is done in the Exadata storage. Building on the high security capabilities in every Oracle Database, the Exadata storage provides the ability to query fully encrypted databases with near zero overhead at hun dreds of gigabytes per second. This is done by moving decryption processing from software into the Exadata Storage Server hardware. The Oracle software and the Intel processors used in the Exadata Storage Server provide Advanced Encryption Standard (AES) support enabling this. The Exadata Storage Expansion Rack is engineered to be the simplest, fastest and most robust way to add additional storage capacity to an Exadata Database Machine or SPARC SuperCluster. A natural extension of the Exadata Database Machine, the Exadata Storage Expansion Rack can be used to satisfy the Big Data requirements of the largest mission critical databases. The Exadata Storage Expansion Rack is designed for database deployments that require very large amounts of data. The expansion rack is extremely simple to configure as there are no LUNs or mount points to configure. Storage is configured and added to a data base with a few simple commands, completed in minutes. Exadata Innovations The Oracle Exadata Database Machine delivers extreme performance and scalability for all database applications whether they are Online Transaction Processing (e.g. SAP ECC 6.0), Data Warehousing (e.g. SAP BW 7.0 and higher) or consolidation of mixed database work loads. One of the key enablers of this is the Exadata Smart Flash Cache hardware and the intelligent Oracle Exadata Storage Server Software that drives it. The Exadata Smart Flash Cache feature of the Exadata Oracle Exadata Database Machine for SAP Customers Storage Server Software intelligently caches database objects in flash memory, replacing slow, mechanical I/O operations to disk with very rapid flash memory operations. The Exadata Storage Server Software also provides the Exadata Smart Flash Logging feature to speed database log I/O. Exadata Smart Flash Cache is one of the essential technologies of the Oracle Exadata Database Machine that enables the processing of up to 1.5 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 100 GB/second. Oracle’s Exadata Smart Flash Cache features are unique. Exadata Flash storage is not a disk replacement – Exa data software intelligence determines how and when to use the Flash storage, and how best to incorporate Flash into the database as part of a coordinated data caching strategy. Scale out Exadata storage enables the benefits of flash performance to be delivered all the way to the application. Traditional storage arrays have many internal and network bottlenecks that pre vent realizing the benefits of flash. Flash can be added to storage arrays, but they cannot deliver much of the potential performance to applications. Oracle has implemented a smart flash cache directly in the Oracle Exadata Storage Server. The Exadata Smart Flash Cache holds frequently accessed data in very fast flash storage while most of the data is kept in very cost effective disk storage. This happens auto matically without the user having to take any action. The Oracle Flash Cache is smart because it knows when to avoid trying to cache data that will never be reused or will not fit in the cache. The Oracle Database and Exadata storage allow the user to provide direc tives at the database table, index and segment level to ensure that specific data is retained in flash. Tables can be moved in and out of flash with a simple com mand, without the need to move the table to diffe rent tablespaces, files or LUNs like you would haveto do with traditional storage with flash disks. The Exadata Smart Flash Cache is also used to reduce the latency of log write I/O eliminating performance bottlenecks that might occur due to database logging. The time to commit user transactions is very sensitive to the latency of log writes. When using Exadata, much SQL processing is offloa ded from the database server to the Exadata cells. Exadata enables function shipping from the database instance to the underlying storage in addition to pro viding traditional block serving services to the data base. One of the unique things the Exadata storage does compared to traditional storage is return only the rows and columns that satisfy the database query rather than the entire table being queried. Exadata pushes SQL processing as close to the data (or disks) as possible and gets all the disks operating in parallel. This reduces CPU consumption on the database server, consumes much less bandwidth moving data between database servers and storage servers, and returns a query result set rather than entire tables. Eliminating data transfers and database server workload can greatly benefit data warehousing queries that traditionally become bandwidth and CPU constrained. Eliminating data transfers can also have a significant benefit on online transaction processing (e.g. SAP ECC 6.0) systems that often include large batch and report processing operations. Exadata is totally transparent to SAP applications using the database. The exact same Oracle Database 11g Release 2 that runs on traditional systems runs on the Database Machine – but on Database Machine it runs faster. Existing SQL statements, whether ad hoc or in packaged e.g. SAP or custom applications, are unaffected and do not require any modification when Exadata storage is used. The offload processing and bandwidth advantages of the solution are delivered without any modification to the application. All fea tures of the Oracle Database are fully supported with Exadata. Exadata works equally well with single-in stance or Real Application Cluster deployments of the Oracle Database. Functionality like Oracle Data Guard, Oracle Recovery Manager (RMAN), Oracle GoldenGate, and other database tools are administered the same, with or without Exadata. Users and database administrators leverage the same tools and knowledge they are familiar with today because they work just as they do with traditional non-Exadata storage. Since the same Oracle Database and functionality exist on the Database Machine as on traditional systems, the IT staff managing a Database Machine must possess similar knowledge about this same software they will manage on the Database Machine. Oracle Database administration, backup and recovery, RAC, Oracle Solaris, and OL experience are important to possess when managing a Database Machine. 9 10 Oracle Exadata Database Machine for SAP Customers Exadata Smart Flash Cache Each Exadata cell comes with 384 GB of Exadata Smart Flash Cache. This means in the Database Machine X2-8 and Full Rack X2-2 there is 5.3 TB of Flash – larger than most databases. This solid state storage delivers dramatic performance advantages with Exadata storage. It provides a ten-fold improvement in response time for reads over regular disk; a hun dred-fold improvement in IOPS for reads over regu lar disk; and is a less expensive higher capacity alternative to memory. Overall it delivers a ten-fold increase performing a blended average of read and write operations. One of the key enablers of Exadata’s extreme perfor mance is the Exadata Smart Flash Cache hardware and the intelligent Oracle Exadata Storage Server Software that drives it. The Exadata Smart Flash Cache feature of the Exadata Storage Server Software intelligently caches database objects in flash memory, replacing slow, mechanical I/O operations to disk with very rapid flash memory operations. The Exadata Storage Server Software also provides the Exadata Smart Flash Logging feature to speed database log I/O. Exadata Smart Flash Cache is one of the essential technologies of the Oracle Exadata Database Machine that enables the processing of up to 1.5 million random I/O oper ations per second (IOPS), and the scanning of data within Exadata storage at up to 75 GB/second. Exadata Storage Capacity, Performance, Bandwidth and IOPS The Oracle Exadata Storage Servers comes with eit her twelve 600 GB 15,000 RPM High Performance SAS disks or twelve 3 TB 7,200 RPM High Capacity SAS disks. The High Performance SAS disk based Exadata Storage Servers provide up to 3.25 TB of uncompressed useable capacity, and up to 1.8 GB/ second of raw data bandwidth. The High Capacity SAS disk based Exadata Storage Servers provide up to 16 TB of uncompressed useable capacity, and up to 1.3 GB/second of raw data bandwidth. When stored in compressed format, the amount of user data and the amount of data bandwidth delivered by each cell significantly increases. The performance that each cell delivers is extremely high due to the Exadata Smart Flash Cache. The Exa data software can simultaneously scan from Flash and disk to maximize bandwidth. The automated caching within Flash enables each Exadata cell to deliver up to 5.4 GB/second bandwidth and 125,000 database IOPS when accessing uncompressed data. When data is stored in compressed format, the amount of user data capacity, the amount of data bandwidth and IOPS achievable, often increases up to ten times, or more. This represents a significant improvement over tradi tional storage devices used with the Oracle Database. Enterprise Manager Support for Exadata Database Machine Oracle Enterprise Manager Cloud Control 12c uses a holistic approach to manage the Exadata Database Machine and provides comprehensive lifecycle manage ment from monitoring to management and ongoing maintenance for the entire engineered system. Integrated System Monitoring Oracle Enterprise Manager provides comprehensive monitoring and notifications to enable administrators to proactively detect and respond to problems with Oracle Exadata Data Machine and its software and hardware components. Administrators can easily ad just these monitoring settings to suit the needs of their datacenter environment. When notified of these alerts, administrators can easily view the history of alerts and associated performance metrics of the pro blem component, such as the network performance of an InfiniBand port or the disk activity of an Exadata storage cell, to identify the root cause of the problem. With direct connectivity into the hardware compo nents of Exadata, Oracle Enterprise Manager can alert administrators to hardware-related faults and log ser vice requests automatically through integration with Oracle Automatic Service Requests (ASR) for imme diate review by Oracle Support. Problems that would have required a combination of database, system and storage administrators to detect in traditional systems can now be diagnosed in minutes because of integrated systems monitoring for the entire Exadata Database Machine.

It follows Oracle’s Engineered Systems philosophy (similar to Exadata) of integrating all components of a system at the factory level providing a highly standardized, optimized and integrated solution that minimizes risk while maximizing performance and reliability. SAP customers are traditionally facing the challenge of building infrastructure for deploying SAP out of individual components: Servers, storage, networking, virtualization, OS, database, etc. This introduces a high amount of complexity and therefore risk, as well as sub-optimal performance due to lack of integration. The power of Engineered Systems such as Exadata and Exalogic show that the right point of integration is at the factory level, where server, storage, networking and software engineers can build a highly integrated, optimized and tested solution that is ideally suited for customer needs. Combining the Oracle Exalogic Elastic Cloud with the Oracle Exadata Database Machine for SAP NetWeaver When running SAP NetWeaver on Oracle Exalogic, it uses an Oracle database for SAP running on an Oracle Exadata database machine. The Oracle Exadata Database Machine is an easy to deploy solution for hosting the Oracle Database that delivers the highest levels of database performance available. The Exadata Database Machine delivers outstanding I/O and SQL processing performance for online transaction processing (OLTP), data ware housing (DW) and consolidation of mixed workloads. Exalogic connects to Exadata through the same highspeed, low-latency InfiniBand fabric that is used inside the systems, providing a scalable and powerful net working foundation for communication between nodes in a system, as well as for scaling across multiple Exa data and Exalogic racks. The InfiniBand fabric that spans Exalogic and Exadata components provides the following key ways of simplifying and accelerating SAP NetWeaver instal lations running on Exalogic: • NFS mounts from the ZFS Storage Appliance to SAP application nodes in Exalogic use the InfiniBand infrastructure for faster data transport than traditional TCP/IP over 10 GbE. This benefits both SAP application servers running in Exalogic and Enqueue Servers running on Oracle Exadata. • SAP application servers running the ABAP stack use Oracle Net through Oracle Instant Client to connect to the Oracle database. This enables them to easily use the SDP protocol over InfiniBand at high bandwidth and low latency, bypassing the traditional TCP/IP stack. • All remaining standard TCP/IP connections running on the InfiniBand fabric will benefit from the 4x higher bandwidth per network connection compared to 10 GbE. • Both networking and storage connections to and from SAP NetWeaver application server nodes are handled through a single fabric, reducing com plexity and improving reliability through using reduced component counts. In addition, IP over Infiniband can be used for the communication between the SAP work processes and the Enqueue Server on Exadata. Compared to typical alternatives, Oracle Exalogic delivered 2-3x improved OLTP performance due to its superior I/O connectivity to Exadata.1 While detailed SAP performance data is not yet available, we expect 1) Please see the Oracle white paper Using SAP NetWeaver with the Oracle Exadata Database Machine for details on how to set up Exadata for use with SAP www.oracle.com/sap Oracle Exalogic for SAP Customers – SAP Oil & Gas 2005 / 6.x – SAP Banking Services 5.0 / 6.0 / 7.0 / 8.0 • Running SAP on Exalogic is only supported as a Three-Tier SAP installation. SAP instances run on the Oracle Exalogic Elastic Cloud server nodes. The Oracle database for SAP must run on an Oracle Exadata system. Oracle Exalogic can only be used in combination with Oracle Exadata and may not be used in combination with other database server hard ware or non-Oracle databases. In this setup, SAP Central Services need to run on the Exadata system. Exalogic to deliver similar performance gains for SAP NetWeaver as well. Exalogic is also the best solution for realizing the full performance benefits of Exadata for SAP, because it integrates directly into the the heart of the Exadata backplane: The InfiniBand fabric. The following image illustrates the relationship between the SAP components, Exadata and Exalogic in a Three-Tier configuration: Simplicity is another key advantage for SAP on Exa logic: Because all components of Exalogic have been engineered, assembled and tuned together at the factory, set-up time is reduced by up 95%. And by reducing risk of errors, simplifying diagnosis, and enabling more efficient, lower-cost operation, total infrastructure costs can be reduced by as much as 60%. Prerequisites for running SAP NetWeaver 7.0 on Oracle Exalogic Elastic Cloud When using Oracle Exalogic Elastic Cloud in SAP environments, the following prerequisites need to be in place: See Oracle White Paper: Oracle Exalogic Elastic Cloud: A Brief Introduction http://www.oracle.com/us/ products/middleware/exalogic-wp-173449.pdf • Only SAP NetWeaver 7.x or higher is supported, including SAP products which are based on SAP NetWeaver 7.x. Please check the SAP Product Availability Matrix for details regarding supported SAP product releases. Examples include: – SAP ERP (ECC) 6.0 – SAP BW 7.x – SAP CRM 2005 / 2007 / 7.x – SAP PLM 6.0 / 7.0x – SAP SRM 2005 / 2007 / 7.x – SAP SCM 2005 / 2007 / 7.x Please see the Oracle white paper Using SAP NetWeaver with the Oracle Exadata Database Machine for details on how to set up Exadata for use with SAP (http://www.oracle.com/us/products/data base/sap-exadata-wp-409603.pdf). • Only Unicode installations of the SAP Software are supported. • As of this time, only Oracle Exalogic X2-2 models are supported. • As of this time, only Oracle Linux is supported as the operating system on the Oracle Exalogic Elastic Cloud server nodes. The minimum release is Oracle Linux 5 Update 5. Both kernels are supported: The Red Hat Enterprise Linux compatible kernel and the Unbreakable Enterprise Kernel (UEK), which is recommended. • Solaris 11 support is planned for a later date. 15 16 • The minimum supported Oracle Database Release is 11g Release 2 Patchset 1 (18.104.22.168) on Oracle Exadata with SAP Software on Oracle Exalogic. Using the ZFS Storage Appliance in Exalogic for SAP Environments The ZFS Storage Appliance included in the Oracle Exalogic Elastic Cloud is ideally suited to act as a “Central Storage Repository for SAP” by providing shared file systems in a highly available and high performance manner for the complete SAP landscape, consisting of application servers running on Exalogic servers nodes and the SAP Central Services running on Exadata. This configuration offers one of the highest potential service levels and throughput compared to more traditional implementations. The ZFS Storage Appliance supports the concepts of Projects and Shares for allocating and organizing sto rage to users, applications and other consumers. In the case of SAP storage for Exalogic, the following strategy is recommended: • One project per SAPSID, with three shares per project: 1. “usrsap” for the /usr/sap/<SAPSID> directory, 2. “sapmnt” for the /sapmnt/<SAPSID> directory, 3. “oracle” for the /oracle/<SAPSID>/<RELEASE> directory. Furthermore, additional Oracle ZFS Storage Appliances connected to Exadata and Exalogic using the same back-plane InfiniBand network can be used as a target for very fast backups from the Oracle Exadata Data base Machine and from Oracle Exalogic, providing a simple, reliable and powerful off-site backup and replication option. Using the Oracle ZFS Storage Appliance as the Central Storage Repository also leverages the facility to easily create unlimited additional Application Servers with minimal effort using the ZFS “snapshot” and “clone” capabilities of the appliance. Because of the broad variety of supported protocols, including HTTP which allows access to the ZFS appliance through WebDAV, ZFS Storage Appliances can be used in combination with Exalogic to imple ment SAP’s ILM concept using either the standard ArchiveLink ADK or the XML Direct Archiving Service. High Availability for SAP NetWeaver on Oracle Exalogic and Oracle Exadata Inside Oracle Exalogic, all servers, networking compo nents and connections as well as other infrastructure components such as power distribution systems are fully redundant. Similarly, the Oracle Exadata Database Machine, where the Oracle database for SAP and the SAP Central Services are running, is composed out of fully redundant components as well. • One project “trans” with one share “saptrans” for the /usr/sap/trans directory. • One project “oracle” with one share for providing the /oracle directory and one share per Oracle client software release, mounted as /oracle/client/<RELEASE>. Therefore, Exalogic and Exadata are ideally suited for setting up a highly available infrastructure for SAP. Since both systems leverage industry standard x86 servers for running applications, standard practices like Oracle RAC, Oracle Clusterware or Oracle Data Guard can be used unchanged for making the Oracle database, SAP services and application servers highly available. Oracle Exalogic for SAP Customers The following SAP support notes are helpful in setting up HA for SAP on Exalogic and Exadata: • SAP Note 1552925 – Linux: High Availabillity Cluster Solutions • SAP Note 1496927 – Protection of SAP instances through Oracle Clusterware Expanding Capacity through multiple Exadata and Exalogic systems In addition to extreme performance, lower risk, simplified deployment and operations, Exadata and Exalogic offer a simple and comprehensive way of scaling the SAP NetWeaver infrastructure. Within a rack, both Exadata and Exalogic offer de ployment units of a quarter, half or a full rack. By using the InfiniBand fabric, multiple racks can be joined together to quickly and easily grow the under lying infrastructure. Conclusion The Oracle Exalogic Elastic Cloud offers a simple, reliable and high performance solution for providing infrastructure to SAP application servers, in combi nation with the Oracle Exadata Database machine. Especially in consolidation scenarios, where Exalogic is used as a platform for hosting WebLogic, Oracle and other applications, the recent certification of SAP for Exalogic allows the consolidation of SAP dev, test and production environments onto Exalogic as well, maximizing the utilization of Exalogic compute nodes. Furthermore, environments that are especially sensi tive to network latency can greatly benefit from Exa logic’s direct Infiniband connection to Exadata as a way of minimizing network latency by a factor of 10 while maximizing bandwidth by a factor of 4. Installation of SAP on Exalogic is straightforward and leverages existing Oracle Linux best practices for running SAP on x86 systems, as well as the innova tive Oracle ZFS Storage Appliance that is built-in into Exalogic. High availability for SAP can be achieved through leveraging standard mechanisms such as Oracle RAC, Oracle Clusterware, Oracle Data Guard etc. Through growing Exalogic and Exadata from Quarter to Half and Full Rack configurations and by adding more racks of Exalogic and Exadata, Exalogic provides a very flexible and scalable infrastructure solution for SAP, while maintaining simplicity and high levels of stability. For growing SAP NetWeaver 7.x environments, this capability offers a simple, quick, low-risk, and modu lar growth path. This avoids the typically long, com plex, time and resource intensive, and error-prone process of selecting, qualifying, acquiring, testing, and quality assuring of multiple individual components. Instead, with the Oracle Exalogic Elastic Cloud and the Oracle Exadata Database Machine, infrastructure for SAP environments of any size can now be instal led and expanded in a matter of days instead of months, while substantially reducing TCA and TCO costs. With Oracle Exalogic and Oracle Exadata, deploying simple, reliable and high performance infrastructure for SAP can now be achieved quickly, cost-effectively and at low risk, compared to traditional ways of deployment.

It’s a complete package of software, server, storage, and networking that’s engineered for simplicity; saving time and money by simplifying deployment, maintenance, and support of highly available database workloads. Fully Redundant Integrated System Providing access to information 24/7 and protecting databases from unforeseen as well as planned down time can be a challenge for many organizations. Indeed, manually building redundancy into database systems can be risky and error-prone if the right skills and resources are not available in-house. The Oracle Database Appliance is designed for simplicity and reduces that element of risk and uncertainty to help customers deliver higher availability for their databases. The Oracle Database Appliance hardware is a rackmountable system containing two Oracle Linux servers and one storage shelf. Each server features two 8-core Intel Xeon E5-2690 processors, 256 GB of memory, and 10-Gigabit Ethernet(10GBase-T) external networking connectivity. The two servers are connected together via a redundant 10-GbE interconnect for cluster communication and share direct-attached high performance SAS storage. The appliance contains 18 TB of raw storage that’s doublemirrored or triple-mirrored, offering 9 TB or 6 TB, respectively, of resilient usable database storage. And, there are four 200 GB solid-state disks for the database redo logs to boost performance. The appli ance is also designed with mission-critical require ments in mind, with hot-swappable and redundant components. The Oracle Database Appliance runs Oracle Database, Enterprise Edition, and customers have the choice of running Oracle Real Application Clusters (Oracle RAC). Oracle Database Appliance Certified for SAP Ease of Deployment, Management, and Support To help customers easily deploy and manage their databases, the Oracle Database Appliance features the Appliance Manager software for one-button automa tion to provision and diagnose database servers. The Appliance Manager feature greatly simplifies the deployment process and ensures that the database configuration adheres to Oracle’s best practices. Its built-in diagnostics also monitor the system and detect component failures, configuration issues, and deviations from best practices. Should it be necessary to contact Oracle Support, the Appliance Manager collects all relevant log files and environmental data into a single compressed file. In addition, the Oracle Database Appliance Auto Service Request (ASR) feature can automatically log service requests with Oracle Support to help speed resolution of issues. Certified and Supported for SAP All SAP products and solutions based on SAP NetWeaver Technology using a minimum SAP NetWeaver Version 7.0 are certified and supported to be used with the Oracle Database Appliance. Therefore SAP products such as SAP ERP 6.0, SAP ECC 6.0, SAP BW 7.0, SAP CRM 7.0, SAP SRM 7.0 or SAP Solutions such as SAP Banking Services version 7.0 can be used with the Oracle Database Appliance. The Oracle Database Appliance provides the following capabilities for an SAP environment: • Highly available active-active clustered database server for SAP Applications • Highly available file server for SAP required shared file systems such as /sapmnt • Complete clustering solution for SAP High Availability Resources such as Central Services for both ABAP and JAVA stack While the SAP database administration tools (BR*Tools) and the SAP Central Services (SCS and ASCS) can be deployed and run on the Oracle Database Appliance, SAP application instances have to run on separate machines which use the Ethernet network to exchange data with the database(s) on the Oracle Database Appliance. In SAP terminology this is called a three tier architecture. This flexible three tier architecture allows for any combination of hard ware and operating systems running the SAP instances to be used with the Oracle Database Appliance. So for example you can run or keep exi sting SAP Application servers on Solaris, AIX or HP-UX platforms connected to the Oracle Database Appliance. This flexibility allows for an easy intro duction of the Oracle Database Appliance in existing SAP environments as it leaves the SAP application layer unchanged. 23 24 O R A C L E V M S E RV E R F O R X 8 6 V I RT U A L I Z AT I O N N O W AVA I L A B L E F O R S A P C U S T O M E R S Oracle VM Server for x86 is a free server virtualiza tion and management solution that makes SAP and other enterprise applications easier to deploy, manage, and support.

For the implementation, Oracle Exadata Database Machine was selected as their integrated database infrastructure. By switching the database for their accounting system running on SAP ERP 6.0, application speeds have dramatically improved, while large-scale storage compression has been achieved. Lion has reaped great rewards with migra tion work that took only two and a half months. They are also planning a future migration of their Teradata information system to Oracle Exadata as part of their proactive efforts further to reduce costs. Migration of business applications to the cloud Building an integrated database infrastructure Lion is a major Japanese manufacturer of toiletry products including detergents, soaps, toothpaste and the like, pharmaceutical products and chemical goods. Since its founding over 120 years ago, Lion has continued to grow and to expand the scope of its business endeavors. Mr. Masatoshi Utsunomiya, Director of the Integrated Systems Division at Lion, had this to say about Lion’s business prospect “In our business management vision that named “Vision 2020,” we have established plans looking forward from the year 2011 to the year 2020. We have positioned our company aggressively to undertake four specific strategic activities, 1) qualitative growth of domestic business; 2) quantitative expansion in of overseas businesses; 3) development of new business value; and 4) enhancement of organizational learning capabilities.” Moreover, Lion is pushing to penetrate into Korea, China, and countries throughout Southeast Asia, and also to developing countries. IT services provided by their Integrated Systems Division supports all of Lion’s business endeavors. The backbone system is composed of business systems that include order and shipping control, sales control, inventory control, accounting, and human resources control. On average, Lion receives tens of thousands of orders, and ships hundreds of thousands of packages every day. It is highly critical that they maintain a system that enables their de livery to distributors the same day after they receive an order. That is precisely IT Services’ mission. Additionally, from the viewpoint of management, keeping down TCO associated with IT Services is also a key issue. Hence, Lion migrated their business applications that were running on mainframes to a private cloud. They also took proactive steps for their open-system database toward switching from decentralization of each system to an integrated system that works as a shared infrastructure. Oracle Exadata for SAP at Lion Mr. Utsunomiya added, “When we operated data base setups for each system, version control or ap plying security patches was always a very time consuming task.” Then, in June, 2010, Lion intro duced a six-terabyte (TB) Oracle Exadata Database Machine V2 which they initially utilized as their backbone system as database migrated from the mainframe. Says Mr. Utsunomiya: “Oracle Exadata supported online data updates from the transaction processing.” The SAP accounting database also integrated to Oracle Exadata The next target for database integration was the SAP ERP 6.0-based accounting system which had been running since 2006 on an open system. Lion completed its migration to a private cloud in August, 2011 as the servers were aging. At the beginning of 2011 when the migration plan was made, Oracle Exadata was not an SAP-certified platform. For that reason, Lion used a cloud service also for Oracle Database 11g and the storage. In June, 2011, just before operations began, Oracle Exadata obtained SAP certification. Mr. Utsunomiya said: “We intended from the beginning to integrate our accounting database to Oracle Exadata, so we started considering it early on when we heard of the product from Oracle Japan.” As a result, they found that Oracle Exadata X2-2, the upgraded version, was a SAP-certified plat form. Lion set about completing all the necessary internal procedures by the end of 2011, and star ted the project in order to migrate their database from the cloud at the beginning of 2012. Mr. Katsuya Utsugi, a manager in the supervising section of the Integrated Systems Division that supervises the accounting system at Lion, said “When we migrated our database from the private cloud, we did not have to set detailed require ments.” Lion had carefully verified Oracle Exadata’s performance with benchmark tests when they introduced it in 2010, and found it to be adequate. 27 The SAP accounting database also integrated to Oracle Exadata Backbone system (mainframe) • Sales distribution • Master control • Initial cost control • Sales analyses (DWH) Accounting system (SAP) • Runs with Linux • Integrates development, testing, production environment The storage had enough free space, so Lion could forecast that detailed sizing would not be necessary. Work actually commenced in the middle of Feb ruary in 2012. Mr. Utsugi added “We were able to upgrade Oracle Exadata from V2 to X2-2 with about 10 days of preparation time, and to com plete it over a weekend. Then we could switch databases in about two and a half months.” Lion needed to ensure that their migration was secure and completed in a short amount of time, so for the upgrade and migration, they relied on support from ACSS (Advanced Customer Support Services) at Oracle Japan. Lion also utilized the O2O (Oracle to-Oracle) Migration Service for database migra tion. Three SAP ERP environment databases, namely one for development, one for verification and one for production use, were targeted for migration. One rehearsal was carefully conducted for actual use. By switching databases over the last Saturday and Sunday of May, Lion was able to migrate its databases without any disruption to its accounting division’s work. 20x faster for SAP accounting sys processing 50% storage compression Reduces maintenance and operating costs Teradata replace integration in the planning stage 28 Oracle Exadata for SAP at Lion 20x increase in accounting query processes speed with half for storage consumption “We intended from the beginning to integrate our accounting database to Oracle Exadata, so we started considering it The Integrated Systems Division at Lion was extremely satisfied with the migration results. The new system improved speeds 20x for a portion of accounting query, compared to processing speeds they experienced while referencing in the private cloud. For that reason and others, the Accounting Division has given the system high marks. Furthermore, by utilizing Advanced Compression in Oracle Database 11g to its fullest, Lion success fully achieved a major reduction in storage con sumption. The 1.4TB-database volume on their cloud storage has been reduced to approximately 700GB or half of that with the new integrated database infrastructure. early on when we re ceived information about the product from Oracle Japan.” – Masatoshi Utsunomiya, Lion Corporation, Director of System Department Lion will continue to push forward with improve ments in their operation and control structure according to increases in business systems that use their integrated database infrastructure. “We are vertically split – the person in charge at each business unit watches over everything from appli cations to hardware.” Mr. Utsunomiya added in his evaluation that “by integrating our database with Oracle Exadata, we can now leave the database-layer to our central database administrator.” With the success of migration of their accounting system database, Lion began at a heightened speed to integrate databases in other business systems that are still running in the open system. Lion is planning to migrate their information systems from datawarehouse-dedicated Teradata (capacity: 1.6 TB) to Oracle Exadata soon. Thereafter, Lion is considering integrating their manufacturing control systems and supply and demand control systems by the end of 2013. From 2014, Lion is forecasting that they will proceed with preparing countermeasures to ensure sustained business and to handle natural disasters by implementing repli cation at a backup site. By migrating business system applications to private cloud and integrating databases to Oracle Exadata, Lion successfully keeps TCO down, while ensuring their system infrastructure is strengthe ned. These are positive steps toward achieving their basic strategy of Vision 2020. To achieve these strategic goals, Lion will continue utilizing Oracle products and services.

Wuhan, China Industry: Automotive Employees: Dongfeng Motor Co., Ltd. (DFL) was established on June 9, 2003 as a joint venture between Dong feng Motor Corporation and Nissan Motor Co. It is the biggest joint-venture enterprise in China’s automotive sector, with registered capital valued at US$2 billion. In July 2011, DFL launched a 2011 to 2015 de velopment program, which will be worth around US$7.9 billion to the Chinese economy. The program will increase the company’s sales from 1 million to 2.3 million vehicles and its sales outlets from 1,400 to 2,044. 70,000 Annual Revenue: Over $5 Billion DFL needed to ensure its IT services and infrastruc ture could support this rapid business development, while minimizing infrastructure implementation and maintenance costs. Oracle Product and Services: • Oracle Exadata Database Machine • Exadata Storage Server Software The company developed a private cloud database based on Oracle Exadata Database Machine to integrate enter prisewide data services and support its SAP-based, spare-parts, logistics manage ment system and in-house-developed, distributor-management system. By taking advantage of Oracle Exadata’s superior performance, DFL has easily supported both systems on a single database machine. In preliminary tests, Oracle Exadata improved the performance of the spare parts logistics management system by 15x, compared to its legacy architecture-based database environment. The database machine also provides the storage capacity and scalability to easily support the expect ed growth in sales, products, and concurrent system users over the next three years. This will save DFL a significant amount in system upgrade costs. In addition, running the distributor management system centrally on Oracle Exadata ensures DFL can support the large volume of data in the com pany’s distributor-management system and the rapid increase in system users. This will signifi cantly reduce the hardware required, compared to running the system separately at each location. Why Oracle? DFL chose Oracle products to develop its private cloud database as Oracle Exadata’s integrated hardware and software offers high reliability, easy integration and scalability, reduced costs, and is convenient to manage. The company was attracted to Oracle Exadata’s excellent performance, which significantly reduced purchasing costs by elimina ting the need for extra database software and disk arrays. Oracle Exadata would also improve the company’s return on investment for its private cloud database, and save energy, data center space, and management and service expenses. In addition, DFL was impressed by Oracle’s com plete, enterprise, cloud lifecycle management solution. It is currently testing Oracle Enterprise Manager 12c, which offers a consolidated view of the Oracle Exadata hardware and software. This will help DFL centralize its systems and simplify system and data center management, improving IT service quality and reducing operational costs. Implementation Process DFL purchased an Oracle Exadata Database Ma chine X2-2 Quarter Rack in November 2011, engaging Oracle Diamond Partner Accenture and Oracle partner Shenzhen Lan-You Technology Co., Ltd. to install the machine at the company’s data center in Huadu District, Guangzhou. Shenzhen Lan-You Technology deployed the test and develop ment environment later that month, followed by the main Oracle Exadata hardware in December 2011. Oracle Exadata for SAP at Dongfeng In January 2012, the Oracle partners deployed the databases for the spare parts logistics management and distributor management systems. Due to Oracle Exadata’s pre-assembled, configured, and balanced, out-of-the box features, the deployment time was reduced from one month to one week, minimizing the impact on the company’s opera tions. In March 2012, the partners carried out perfor mance tests and additional tuning, and deployed and tested the management monitoring tool. The spare parts logistics management and distri butor management systems went live on the Oracle Exadata-based, private, cloud database in mid-2012. Partner • Oracle Partner • Shenzhen Lan-You Technology Co., Ltd. • Accenture Shenzhen Lan-You Technology helped DFL purchase Oracle Exadata, coordinate its related IT resources, and install the software and hardware. The partner also helped commission and conduct application software, equipment operation, and maintenance management tests. Accenture deployed the databases for the spare parts logistics management system on Oracle Exadata and took part in the performance tests.

To date, Atos has installed SAP on more than 5,000 systems around the globe. The leading IT service provider is also a long-standing partner to Oracle, hosting or managing more than 4,200 Oracle databases. There are plenty of good reasons why Atos uses the Oracle Exadata Database Machine for SAP, as Guido Maushart, Solution Design Authority at Atos AG, Zurich, explains in the following interview. When did Atos start using the Oracle Exadata Database Machine? Over four years ago. Initially mainly in The Netherlands, one of the global Atos sites where we had over 2000 large database installations. We’ve always wanted IT operations here to be as good and efficient as possible while offering the appropriate performance. Exadata was the perfect solution. The Netherlands is also home to our Global Exadata Competence Center (GECC). Maushart: What is the GECC? What does it do? What were the main reasons for Atos choosing Exadata in the SAP environment? One of the deciding factors was the fact that with SAP response times are seen as critical Service Levels so they really matter. SAP response times are critical to the business. Exadata is able to support entire business processes and dramatically reduce response times with outstanding performance depending on the individual circumstances. Given its high availability, Exadata also allows greater use to be made of the active-active database technology, Real Application Clusters. And does so at minimal cost. Another benefit of Exadata is that it allows SAP database landscapes to be consolidated within SAP and even also with other Oracle databases. For us as an outsourcer, Exadata therefore solves several pro blems at once – all in all, the Oracle Database Machine simplifies IT operation and reduces the total cost of ownership for Oracle database landscapes that run under SAP. And what is true for us in hosting or managed services, is of course also true for SAP customers. Maushart: One of the central jobs of the GECC is to provide support to all the Exadata systems used or supported. It is also responsible for Big Data and Business Analytics. This special global competence center is able to support local organizations in their use of Exadata. Atos has several experienced consul tants and Engineered Systems specialists based here who produce customized proofs of concepts and TCO scans. Maushart: What SAP cases or scenarios does Atos encounter for the POCs? These are usually customized SAP instal lations – and a BW environment, a dedicated ERP infrastructure landscape or an SAP webshop, which almost directly accesses the database and is conside red mission critical. This setup produces concrete facts on performance. Individual key facts, such as response times at RFC interfaces and much more besides, are taken into account. We are also able to indicate the value added from using Exadata, for example a higher level of availability, cost savings from database consolidations etc. An Oracle Exadata X2-2 half rack is currently used for this purpose. Atos also currently uses 26 Exadata systems for non-SAP work. Maushart: Atos IT – Oracle Exadata Services for SAP Customers And what about the TCO scans you mentioned? The idea behind these TCO scans is to take stock of a particular customer environment to allow us to quickly comment on costs and benefits, inclu ding potential for optimization, ROI and value added from using Exadata. In short, whether it’s worth using Exadata and if so, how. Based on our far-reaching experience of IT operations, the results of these TCO scans are important decision-making bases which companies need when using a new system. Maushart: Has there been anything in particular that you have learned from the Exadata POCs or TCO scans thus far? We always start with performance; it’s our main concern. We’ve identified two performance as pects to which customers are most sensitive. Firstly of course Exadata generally results in better response times. Secondly, we’ve really noticed communication links, especially the RFC interfaces in the SAP envi ronment. More and more importance is being attached to the best possible way of interacting with peripheral or sub-systems. Again Exadata can bring optimizati ons – ultimately improving the dialog performance of complete IT systems. Maushart: From what you have seen, how do companies using SAP benefit in particular from Exadata in the SAP environment? As I’ve already said, SAP customers gain important benefits from enhanced performance – also in terms of backup performance. Using Exadata, they also stand to gain from optimized high availability for both unscheduled and scheduled downtimes. The latter applies especially to maintenance. Exadata shortens maintenance windows because the patch management time is minimized thanks to standardized components in a stack and is also associated with less risk. For global companies which have to provide SAP operation 24/7 – which is most companies these days – this is a crucial benefit. Maushart: And security also benefits from Exadata through the Oracle Enterprise Vault solution provided by Exadata. For example, there is no scope for forgetting a compo nent in patches. And this is something that shouldn’t be underestimated. By way of conclusion, we have found that using Exadata delivers multiple, clearly demonstrable benefits for IT and the business. 35 36 “We chose Oracle Exadata over products from other vendors for its cost-efficiency; reduced hardware, data center, and energy requirements; and faster implementation times. We have established a centralized, enterprisewide, private-cloud platform for our core business applications and cut system maintenance and operational costs by 80%.” – D I N G TA O , Vice General Manager, Information Management Department, Shenhua Group Corp.

It also wanted to conform to international IT development trends. “We evaluated various domestic and international IT vendors but chose Oracle Exadata for our pri vate cloud platform, due to its cost-efficiency; reduced equipment, data center, energy, mainten ance, and management requirements; and faster implementation times,” said Ding Tao, vice gene ral manager, information management depart ment, Shenhua Group Corp. Ltd. The company then seamlessly migrated Oracle Siebel CRM and other important resource plan ning systems onto the database machine. In October 2012, Shenhua Group worked with Oracle Diamond Partner Accenture to complete the project by deploying the critical SAP enterprise management systems onto Oracle Exadata. Partner Shenhua Group chose to work with Accenture, due to the company’s strong reputation and exten sive experience. “Accenture had provided consultation services for many large, state-owned enterprises in China, and it had rich experience in implementing Oracle and SAP products,” said Tao. “This experience guaran teed the smooth implementation of Oracle Exadata.” Implementation Process Shenhua Group completed the Oracle Exadata implementation and database migration in several stages. In May 2011, the company implemented Oracle Exadata Database Machine Quarter Rack and con figured Oracle Linux and a third-party hard drive to build its private cloud database platform. It also deployed Oracle Enterprise Manager 12c.

SAP: • IS Retail ECC 6.0; • Netweaver BW 7.3 / BO / POSDM HCM, • Netweaver PI 7.1 Other infrastructure: OS system: Oracle Linux – Suse Linux Enterprise In Koçtas stores, more than 40.000 products are sold; from decorative products to furniture, home textile products, kitchen items, bathroom fixtures, ceramics, garden furniture, lighting products, room sets, ready-made curtains, carpets, paint and floor ing. Koçtas was one of the first companies of the Turkish Koç Holding (USD 43 billion in revenue in 2011), with a history dating back to the 1950s as a wholesaler of construction materials. The com pany entered the retail sector in 1995, opening its first store in 1996 in Izmir Bornova. Over the years store openings continued. Today the leader of the home improvement sector in Turkey owns 37 stores in 19 cities. As business continued to grow, it was only natural for the expansion-focused firm’s data volumes to also increase year on year. But that wasn’t all. The use of IT and the demands placed on it, especially on the IT infrastructure when using corporate SAP solutions, have continued to grow over time at Koçtas. Since 2002, Koçtas has used central infra structure components from Oracle and Sun for its retail software: on the SAP market leading Oracle Database and Sun’s high-performance database and application servers. From Oracle Sun to Oracle Sun As Koçtas make intensive use of SAP’s core cor porate application systems, the IT infrastructure obviously had to be adapted to requirements over time, not least because of the increased number of users. However, in the past most of this tuning work had been very localized, for example in the storage area or in terms of the servers used. Koçtas currently has around 2,000 SAP users, around 800 of whom are intensive users. In mid-2012, the company needed to radically change its infrastructure. “Last year we were forced to think about restructuring our infrastructure. We were wanting several, long-term optimizations ranging from improved performance in our use of SAP applications, better cost effectiveness or simpler system handling to even better system availability of corporate applications,” explains Koçtas IT Director, Orkun Sueer. A solution which proved ideal to Koçtas was quick ly found: the Oracle Exadata Database Machine for SAP which allowed several important requirements to be met at the same time. Oracle’s Database Machine combines hardware, networking and software in one optimized system to deliver maximum performance for little cost, and is an ideal platform for customized company-wide database use. Oracle Exadata for SAP at Koçtas Why Oracle? Oracle has long numbered among the company’s strategic partners. Oracle’s solutions represent the future high-performance platform for missioncritical applications and offer incomparable perfor mance, availability and administrative efficiency, particularly as it dramatically simplifies the com plexity of heterogeneous infrastructures. As a successful company, Koçtas consistently relies on modern technologies to drive business growth. In use: Exadata X2-2 quarter rack From a strategic standpoint, the main reasons for Koçtas opting for Exadata were as follows: “We opted for Exadata for SAP because of its modern scale-out infrastructure. Oracle Exadata will clearly have benefits for us. We will be able to gain impor tant performance boosts and we can also we save costs through the consolidation of multiple work loads in a single infrastructure”, Mr. Sueer said. In terms of operations, the ability to significantly improve performance and system output when using SAP Business Warehouse was a crucial factor in the company selecting the Oracle Exadata Database Machine. Furthermore, Exadata is ideal for con solidating SAP database landscapes – with the corresponding cost savings. The firm’s IT team was assisted in implementing Oracle Exadata, or more precisely, in migrating the previous system environment to the new one with Oracle Exadata, by its long-standing IT service provider KoçSistem. KoçSistem is also part of the Koç Holding and provides Koçtas with a number of IT services and outsourcing services. Tests demonstrated boost in performance Koçtas IT, the service provider/outsourcer and Oracle worked together to gradually implement a defined migration plan. They had decided to use a quarter rack version of the Oracle Exadata Database Machine X2-2 with 24 Database Grid Cores and 192 Database Grid Memory. The system environment including Exadata was virtually as good as new. In other words, the application servers were also replaced, a process involving migration from Sun to Sun. As Koçtas IT Director Sueer says, “once a test system environment had been established, very thorough system analyses were undertaken. Around 250 relevant SAP transactions were used for extensive testing with the new infrastructure. We expected the Oracle Exadata Database Machine to significantly improve performance and the results confirm that it did just that.” Further testing, including an integration and high availability test, was then carried out and a migra tion system environment set up (as a QA system) followed by the actual productive system environ ment. One of the last steps was to transfer data from the previous SAP ERP database to the Exadata Database Machine by using SAP tools. This step in the migration process involving the transition (database export/import) of a data volume of around 2.7 TB (total database volume of all Oracle SAP database) was also played through several times. Everything went fully according to plan and the new modern scale-out infrastructure with the Oracle Exadata Database Machine X2-2 for SAP went into operation in March 16 2013 as scheduled. Until August, our project team will complete the migration of BW. 39 40 Oracle Exadata for SAP at Koçtas Highly satisfied – “huge, huge benefit” As Koçtas IT Director Sueer says, “the performance improvements gained by using Exadata for SAP ECC queries alone represent a huge, huge benefit. There is a huge difference between whether a report takes minutes or seconds to produce. The end result is that important information is made avai lable faster in many parts of the company and business decisions can be made faster.” The tests carried out show that Oracle Exadata has enabled the query performance to be improved by around 400 percent (In some reports 10 times). And one of the reasons for this is the much faster data throughput which Exadata provides thanks to its unique technology concept. But the firm’s IT department doesn’t see this as the end of the road. They are expecting “average overall performance to also be improved to above-average levels through fine tuning.” One of the 37 Koçtas stores in Turkey It is also assumed that the money invested in the new SAP IT infrastructure will be paid off very quickly and that IT costs can be saved – simply by consolidating the database using the Oracle Exadata Database Machine. But that’s not all. As Mr. Sueer explains, “now we can easily realize the power of Exadata by experi encing the improvement of our own SAP applica tions running on Exadata without any changes at application level.” This enables the company to effortlessly and quickly incorporate more applica tion servers into the environment. What’s more Oracle Exadata has allowed Koçtas to further improve its high availability level. As Koçtas IT Director Sueer says by way of con clusion, “the move to the Oracle Exadata Database Machine was well worth it. We’ve got all perfor mance requirements covered in our use of SAP – both for now and the future. We benefit in many ways from the numerous benefits we gain from the Oracle Exadata Database Machine. Throughout the company, not just in the IT department.” 100% of the Global Fortune 100 Get Better Results With Oracle Oracle.com/industries or call 1.800.ORACLE.1 Copyright © 2012, Oracle and/or its a affiliates.

Many nonSAP applications (PLM, asset management, BDE/BME) run on Oracle Database 11g as well. In addition, the multinational corporation has long relied on Oracle’s Advanced Customer Support Services (ACS). And since the end of January 2012, the customer has been reaping the benefits of the Oracle Exadata Database Machine, a one-of-a-kind appliance and outof-the-box solution with innovative, perfectly matched hardware and software. To the Database Machine via Oracle Advanced Customer Services (ACS) “We devote a lot of resources to keeping our systems running smoothly for SAP application use, especially for SAP BW. In many cases, this consists of constantly tuning the systems to maximize overall performance,” explained Group Lead IT. This had been a hot topic of discussion between the IT team and Oracle ACS experts – and the subject of several proposed solutions. Finally, the ACS specialists suggested the Oracle Exa data Database Machine in the spring of 2011 and gave a presentation in July. SAP customer with Oracle Exadata Machine in production According to the ERP expert, “We loved the Oracle Exadata Database Machine from the start. It was clear that Oracle’s out-of-the-box solution could greatly optimize our SAP activi ties, not just in terms of performance, but also in terms of minimizing the resources tied up in system tuning, which we were very keen to do.” Though the expectations were high, Oracle Exadata delivered all the hoped-for improve ments in BW and CRM use from the very first day. Plus, not only was the implementation of two X2-2 Exadata quarter racks (with Oracle Database 11g and Oracle Enterprise Linux) completely painless, it was also completed very quickly: in slightly more than three weeks. ECC6.0 on Exadata after BW and CRM The IT team and Oracle ACS joined forces to systematically carry out an Exadata implemen tation project plan; Oracle SAP specialists were brought in as needed. After installing and checking the hardware, the partners got to work on the main step in the project: setting up the 4.5 TB Oracle Exadata Database Machine as the standby database for NetWeaver BW and CRM. This took less than two days, which left plenty of time for testing. Once the preparations were complete, the team “pulled the lever” and switched the BW and CRM database infrastructure over to the Exa data Database Machine. The Exadata standby database had become the production database. As IT Group Lead recalled, “Everything went off painlessly, just as planned. Exadata has been our sole SAP database layer for BW and CRM since January 29.” The Exadata appliance replaced an HP DL580 (database) server (with SUSE Linux) and an EVA8100 storage system (including 4 Gb SAN system), which have been redeployed elsewhere in the company. The customer is already plan ning to move ERP ECC6.0 (including GTS) over to Exadata to improve performance even more. The benefits are enormous The advantages and improvements offered by Oracle Exadata represent a giant leap forward that has delivered countless benefits for the company. “We can make massive reductions in system tuning, which has been a real boon. Between Exadata’s excellent performance and the way in which the data is prepared, we have essen tially eliminated the need to tune our systems for BW use. For example, we no longer have to analyze certain reports or statements and create additional indexes. That lets us put our resour ces to more productive uses,” noted the IT ex pert. Also, the customer has reported enormous improvements in overall BW performance. But it saw entirely new benefits, too. “We can now generate BW reports that were simply unheard of in our pre-Exadata days,” said the SAP application expert. “And that’s a great thing. Not just for us in IT, but also for people in the user departments, whose satisfaction with BW has risen enormously. Exadata has unlocked an entirely new dimension of the application for them.” Before Exadata, many large reports could not be generated because they would time out after reaching the tenminute mark set by the customer. 43 44 SAP customer with Oracle Exadata Machine in production The reports and queries have obviously seen improvements as well – quite dramatic ones, in some cases. According to the company’s measurements, some queries (including revenue queries) are up to 14 times faster with Exadata than the previous database environment. Reduction of complexity When the IT Group Lead says that the Oracle Exadata Database Machine “just inspires a sense of trust and confidence,” he is obviously refer ring to improvements in system tuning and performance. However, he has another issue in mind, too: “reduction of complexity” or, to put it another way, “patch risk reduction.” “Whenever you patch a conventional SAP database environment, you have to look out for compatibility conflicts between compo nents.” A database server patch, for example, may require the switch or storage system to have a particular patch version. Managing all these patches can be extremely complicated. “Exadata, by contrast, is an out-of-the-box solution with perfectly matched and tested components. It doesn’t require time-consuming patching, which drastically reduces and simpli fies our workload,” explained the IT expert. Next, the customer plans to switch ERP ECC 6.0 (including GTS, 5 TB) over to Exadata. The company expects to see additional bene fits from this move. Tests have already shown that data can be loaded from the ERP system to the database much faster with the Oracle Exadata Database Machine. That will give an additional fillip to performance and, by exten sion, user satisfaction. If necessary, the Exadata system can scale up easily and painlessly: The quarter racks can be upgraded to half racks, full racks or multiracks. Will the automotive customer use one of these options? Only time will tell, but it certainly seems possible. After all, in the me dium term, they plan to supply application services to its sites in China and the United States from Germany.

Exadata customers can run Oracle databases with multiple workloads, SAP and non-SAP, on a single Exadata Database Machine. Simple and fast to implement, the Exadata Database Machine is ready to tackle the largest and most important database applications – and often run them up to 10 times faster or even more. Since 2011, SAP customers can use Oracle Exa data Database Machine for their SAP applica tions. As an easy to deploy solution for hosting the Oracle Database it runs SAP unchanged with better performance out-of-the-box, con solidates SAP NetWeaver applications and reduces the number of vendors to just two, SAP and Oracle. It allows better support, fast and online migration, DBaaS deployment platform, advantages of the Enterprise Database Cloud Solution with a rapid deployment of its infra structure and lowers costs through consolida tion. integration, development, and run-time costs were associated with their current database design. “Overall we were concerned about our capability to meet our KPI when outages occur with the existing BW performance and a lack of scalability issues”, stated the IT-department. Federated Reporting was not supported in the current design as all the data was not in one place. Deployment, administration, hardware, and environmental costs had to be reduced drama tically by increasing the performance of data processing and loading, rationalizing and consolidating the Database Infrastructure and derisking future-state SAP BW operations by leveraging the Oracle Exadata communal best practices.

Federated Reporting was not supported in the current design as all the data was not in one place. Decreasing “Time-to-Market” in Food Business One of North Americas largest food retailer operates under 22 banners with 110,000 fulltime and part-time employees over 8,00 cor porate and franchised stores across the country. In 2012 the company expected a data volume growth of 50 to 100 percent. Higher RDBMS with built-in high availability and offering high performance One week after the delivery of the Exadata Database Machine and SAP Database Migra tion significant “Cost to Deploy” savings appeared. A doubling of performance by meanings of a processing time reduction to less than 50% compared to current/latest model of IBM P7 server was recognizable. 45 46 Oracle and SAP teams are currently engaged to further improve this. The Backup time for 5 TB was reduced from 30 hours to 45 minu tes. In regards to a “Green Power” initiative for energy conservation, expenses were signifi cantly lowered by reducing the hardware foot print. Inspiring a Sense of Trust and Confidence A leading manufacturer of electric connection and industrial automation technology located in Germany is benefiting from global demand in the automotive business, a growing market with an increasing data volume. It was clear that Oracle’s out-of-the-box solu tion could greatly optimize their SAP activi ties, not just in terms of performance, but also in terms of minimizing the resources tied up in system tuning. The Exadata replaced an HP DL580 database server with SUSE Linux and an EVA8100 storage system including 4 GB SAN systems, which have been redeployed elsewhere in the company. Migrating SAP ERP to Exadata with RAC on two nodes two IBM 3950 and an IBM DS 5300 Storage system were replaced. When the IT Group Lead says that the Oracle Exadata Database Machine “just inspires a sense of trust and confidence,” he is obviously re ferring to improvements in system tuning and performance. However, he also has another issue in mind: the reduction of complexity and patch risks: “Whenever you patch a conventional SAP database environment, you have to look out for compatibility conflicts between com ponents.” A database server patch, for example, may require the switch or storage system to have a particular patch version. Managing all these patches can be extremely complicated. Exadata, by contrast, is an out-of-the-box solution with perfectly matched and tested components. It doesn’t require time-consuming patching, which drastically reduces and simplifies the workload.

Consequently, each decision related to performance maximization becomes more critical and complex, particularly in today’s outlook. Oracle Exadata is the best solution to ensure optimal performance and fully integrated platform that will support our company’s fast growing pace and success story.” – CYRIL REOL, CIO, Glencore International plc. Customer Success Story Glencore is a leading producer and marketer of com modity products, predominantly in the supply of metals, minerals, energy and agricultural products. It operates 24 hours a day, 7 days a week, supported by a global network of 50 offices in 40 countries throughout Europe, North, Central and South America, the CIS, Asia, Australia, Africa and the Middle East. Over 2,800 people work in its marke ting division, while over 54,800 people are directly or indirectly employed in industrial operations. In today’s globalization, success or failure depends largely on capacity to make the right decision based on the latest information available. A commodity marketer has to understand the political uncertain ties, risks specific to a particular production region, changes in weather conditions that may affect deli very of goods, market volatility on supply/demand, amongst hundreds of unpredictable changes. In order to respond to all these challenges, Glencore has established a solid backbone of trading and risk management platforms, and reporting databases, which allows a dynamic decision making process in its globally distributed business. More than 200 dif ferent IT solutions are operating on a daily basis, with the highest level of transactional integration possible, particularly for its corporate data warehouse and global accounting. A significant part of these key solutions are hosted in Glencore’s headquarter in Baar, Switzerland. As a leading and innovative company, Glencore IT has always had a culture for performance. The reason is obvious: by allowing early adoption of technolo gies that bring a true competitive advantage IT is enabling business opportunities. In that respect, Glencore embraced Oracle Exadata platform as a new foundation for company data warehouse and global SAP programs. Two projects, one goal: maximum availability for mission-critical business “We considered Oracle Exadata solution before it gets fully certified on SAP ECC 6.0, enabling a leading edge solution to support a major accounting program change but certification was an essential prerequisite for our company” recalled Sveto Putinca nin, Head of IT Engineering and Operations. Back in July 2011, Glencore decided to proceed with an evaluation of Oracle Exadata Database Machine with assistance from Tradeware AG, an Oracle Pla tinum Partner based in Switzerland. After reviewing Oracle Exadata core features and capabilities through a Proof of Concept (benefiting from a quarter-rack infrastructure environment for that purpose), Glencore was convinced that Oracle’s new system represented the way of the future. Decision was made to upgrade its global data ware house environment – plus underlying data feed pro cesses – as the new SAP-based global financial solution to Oracle Exadata Database Machine. Oracle Exadata at Glencore Phase 1 The first phase of the Exadata roll-out project was to upgrade Glencore data warehouse environment. A major performance gain was identified, especially in terms of I/O, and due to the high system load. Before considering any migration, Glencore thoroughly tested the platform using an Exadata system which was provisioned by its partner Tradeware. Because the preparation work was crucial, Glencore was able to leverage Oracle GoldenGate with limited issues. It has performed the necessary upgrade tasks of Oracle Database from 10g to 11g. “Any benchmark in terms of performance between the new Oracle Exadata and our previous Oracle environment would be impressive” added Sveto Putincanin. The major improvement is about the generation of business reports that users urgently need to market commodities. In the past, some reports were genera ted overnight due to the volume of data retrieved and processed; now, it appears on the decision maker screens in less than an hour. “This is very valuable in our competitive industry which depends heavily on market information and how you can anticipate change. Being able to quan tify and correlate any technical improvement with the Glencore overall financial performance is quite difficult. Nevertheless, I consider that we have today a key component for future successes” commented Cyril Reol. This first deployment fulfilled all Glencore’s expecta tions placed in Oracle Exadata Database Machine. The underlying components harmonized together perfec tly and particularly increase performance on the I/O side. As a matter of fact, Glencore no longer need to ensure the interoperability of the server, operating system, firmware, storage and other heterogeneous components. Key complexity was visibly reduced, greatly simplifying system operation. Oracle Exadata also drastically reduced the number of systems that had to be administered. It replaced many production, testing and development machines along with the adequate SAN environment. “We saved on resources as well, particularly as the platform only needs to be administered by one team instead of four previously. It will clearly pay off in all our subsequent activities” said Sveto Putincanin. Phase 2 SAP Financial & Controlling solution on Exadata Since Glencore was an early adopter, the Walldorf based Oracle team helped to deploy the first SAP FI/CO environment on Oracle Exadata in Switzerland, as a second step for Glencore. The Oracle experts supported the Glencore team throughout the entire process – from planning, conceptual design, infra structure sizing to production startup – to ensure that no issue might delay this critical program go-live. Glencore’s ambitious new Global Accounting Pro gram – based on SAP FI/CO – aimed to streamline its accounting and financial processes worldwide and across all commodity divisions. It was initially deployed in Baar, Switzerland for its global Metal, Minerals and Coal marketing businesses. Afterwards, the project will be continue across other operations, covering Oil and Gas divisions in UK, US and Sin gapore, plus Agricultural business in The Netherlands. As the Global Accounting Program was launched prior to Oracle announcement about Exadata, Glencore IT had to catch-up quickly during the project and decided to migrate the Test environment first. After wards, Glencore completed the remaining environ ments and went live on SAP FI/CO based on Oracle Exadata Database Machine in January 2012. “We highly valued Oracle's support. Their employees had the required expertise to select the perfect hard ware for our requirements and prepare meticulously for go-live. While there were a few stressful moments for everyone in the project, we went live very smooth ly for an early adopter project” said Sveto Putincanin. “We now have a SAP-certified solution and a single provider supplying the operational support for all its components. Additionally, we can administer and further develop our IT infrastructure more efficiently thanks to the Oracle Exadata solution, making our team even more effective in the future” 49 50 Challenges Solution • Being able to make the right decision based on the latest information available; Glencore, as a leading producer and marketer for commodity products, is operating globally and requiring high-perfor mance solutions. • A Proof of Concept, supported by Oracle partner Tradeware AG, confirms that the new IT environ ment based on Oracle Exadata could deliver the expected performance and reduce the complexity inherent to heterogeneous infrastructures. • Managing the underlying risks to introduce a major technology change while ensuring daily support, best performance and availability for business-critical requirements. • Oracle Exadata Database Machine in conjunction with Oracle Real Application Clusters and Oracle Advanced Compression forms the foundation for a successful architecture. • Identifying eligible applications/projects that would benefit the most of Oracle Exadata improve ments; Glencore selected its data warehouse and new SAP FI/CO program. • Leveraging Oracle GoldenGate to eliminate per formance bottlenecks and to ensure a smooth migration of a complex data warehouse environ ment. • Finding the right partner(s) that would fit into the company culture and support a smooth transitio ning to Oracle Exadata; Glencore established a partnership with Tradeware and Oracle in that respect. • Minimizing the infrastructure's complexity to ensure efficient system operations and to optimize support processes, making its operational team even more effective.

Oracle Exadata at Glencore Why Oracle? As a fast-growing, successful company, Glencore consistently relies on the latest technologies to im prove its competitive edge. Oracle has long numbe red among the company’s strategic partners; it relies on many Oracle products in addition to its database. Oracle Real Application Clusters, for example, effi ciently ensures high availability, while Oracle Advan ced Compression optimizes storage resources. Oracle’s solution represents the future high-perfor mance platform for mission-critical applications and offers incomparable performance, availability and administrative efficiency particularly as it dramati cally simplifies the complexity of heterogeneous infrastructure. Tradeware AG was given the “EMEA Exadata Partner of the Year” award at Oracle Open World 2011 in San Francisco in recognition of its outstanding con tributions.

Customers can choose either clustered or single-servers that run Windows, all major Linux distributions or any major vendor UNIX distributions. It provides comprehensive features to easily manage the most demanding transaction pro cessing, business intelligence, and content management applications. Oracle Database 11g Release 2 Enterprise Edition comes with a wide range of options to extend the world’s #1 database to help grow your business and meet your users performance, security and availability service level expectations. SAP has certified Oracle Database 11g Release 2 (please see SAP Note 1398634) with the following details: • Only SAP products based on SAP Kernel 6.40_EX2, 7.x and higher are certified with Oracle Database 11.2. • A general release of Oracle Database 11g Rel. 2 is not provided for earlier SAP releases (SAP R/3 3.1I up to and including SAP R/3 4.6C). Similar to Oracle Database Version 10.2, there is only a temporary 11.2 release in direct connection with an SAP upgrade project for these older SAP versions. • The SAP release of Oracle Real Application Clusters (RAC) 11g Release 2 occurred at the same time as the general release of Oracle Database 11g Release 2 in the SAP environment. For information about Oracle RAC support, (see SAP Note 527843). It contains important details about the released RAC configurations. • As of Oracle 11g Database version 188.8.131.52, SAP fully supports Oracle Automatic Storage Manage ment Oracle (ASM) and its extended functionality to manage ALL data: Oracle Database files, Oracle Clusterware files and non-structured general pur pose data such as Oracle and SAP kernel binaries, external files and text files. Oracle ASM simplifies, automates and reduces cost and overhead by provi ding a unified and integrated solution stack for all file management needs, eliminating the need for 3rd party volume managers, file systems and clusterware platforms. Oracle ASM has two major enhance ments that are important for running SAP: • Oracle Cluster Repository (OCR) and voting files can be stored on Oracle ASM. • Oracle RDBMS Home can be stored on Oracle’s new cluster file system ACFS. This makes Oracle ASM the preferred storage platform for SAP running on Oracle Real Application Clusters as well as for SAP systems running on a single instance Oracle Database (for more information about Oracle ASM, see the article on page 32). For details see SAP Note 1550133. Oracle Database 11g Release 2 provides customers more benefits: saving disk space with lower hardware costs, more performance, higher security, better manageability, exceeding productivity and at least in an outstanding high availability/disaster recovery for SAP applications. The following provides a list of important features available for SAP customers today and many of them are unique to Oracle. Index Compression The Oracle Database provides a highly efficient techno logy for storing regular indexes in an efficient manner. For performance and throughput reasons almost every access to SAP data in the Oracle Database happens via indexes. Therefore indexes in the database are critical for the throughput of an SAP system. The more efficient indexes are stored in the database the more efficient the SAP application will run. By using index compression in the Oracle Database the performance of the SAP applicaton will be improved. Queries may run three to four times faster using compressed in dexes. Index compression will reduce the total disk space for the Oracle Database by up to 20%. The use of index compression in the Oracle Database for SAP Applications is described in SAP Support Note 1109743 and fully integrated in the BR*Space utility of SAP. Oracle Database 11g Release 2 for SAP D A T A B A S E Compressed Index Organized Tables The Oracle Database provides another important and ideal technology for SAP applications. Many tables used by the SAP application have only a single unique index (primary key). These tables with a single unique index can be stored much more efficient in the Oracle Database by using compressed index organized tables (IOTs). By using compressed IOTs queries may run up to five times faster. Insert and Delete operations against compressed IOTs will perform up to twice as fast. The use of compressed IOTs will reduce the total disk space of the Oracle Database by up to 25%. The implementation of compressed IOTs provides the capa bility to keep single index tables entirely or almost entirely in-memory avoiding any disk IO and there fore providing extremely fast access to data in the Oracle Database. The use of compressed IOTs in the Oracle Database for SAP Applications is described in more detail in SAP Support Note 1856270. OLTP Table Compression Oracle Database 11g introduced a new feature called OLTP Table Compression that allows data to be compressed during all types of data manipulation operations, including conventional DML such as INSERT and UPDATE. In addition, OLTP Table Compression reduces the associated compression overhead of write operations making it suitable for transactional or OLTP environments as well. OLTP Table Compression, therefore, extends the benefits of compression to all application workloads. Oracle’s OLTP Table Compression, part of Advanced Compression, uses a unique compression algorithm that eliminates duplicate values within a database block, even across multiple columns. Compressed blocks contain a structure called a symbol table that maintains compression meta data. When a block is compressed, duplicate values are eliminated by first adding a single copy of the duplicate value to the symbol table. When compared with competing com pression algorithms that maintain a global database symbol table, Oracle’s unique approach offers signifi cant performance benefits by not introducing addi tional I/O when accessing compressed data. The benefits of OLTP Table Compression go beyond just on-disk storage savings. One significant advantage is Oracle’s ability to read compressed blocks directly without having to first uncompress the block. Therefore, there is no measurable performance degra dation for accessing compressed data. In fact, in many cases performance may improve due to the reduction in I/O since Oracle will have to access fewer blocks. Further, the buffer cache will become more efficient by storing more data without having to add memory. Since Oracle Database Rel. 10.2.0.2, SAP has certified the use of Index compression to save disk space for indexes and reduce total database size on disk. Custo mer experiences show that even after a full database reorganization has taken place, an additional 20% of total disk space reduction for the whole database can be achieved using index compression. SecureFile Data Compression SecureFiles is a new feature in Oracle Database 11g that introduces a completely re-engineered large object (LOB) data type to dramatically improve performance, manageability, and ease of application development. SecureFiles data is compressed using industry standard compression algorithms. Compression not only results in significant savings in storage but also improved performance by reducing IO, buffer cache requirements, redo generation and encryption overhead. SecureFile compression provides significant storage and handles in-line and out-of-line LOB data which are getting more and more important in SAP applications and are widely used in SAP pro ducts such as SAP CRM, SAP XI, SAP NetWeaver Portal, and even in SAP ERP. Almost all non-cluster tables in SAP ERP use out offline LOBs that are unique to the Oracle database. RMAN Backup Compression The continuous growth in enterprise databases creates an enormous challenge to database administrators. The storage requirements for maintaining database backups and the performance of the backup procedures are directly impacted by database size. Oracle Advan ced Compression includes compression technology that can dramatically reduce the storage requirements for backup data. Due to RMAN’s tight integration with Oracle Database, RMAN backup (widely used by SAP customers) data is compressed before it is written to disk or tape and doesn’t need to be uncom pressed before recovery – providing an enormous reduction in storage costs. 53 11g 54 D A T A B A S E 11g Data Pump Compression The ability to compress the meta data associated with a Data Pump job was first provided in Oracle Database 10g Release 2. In Oracle Database 11g, this compres sion capability has been extended so that table data can be compressed on export. Data Pump compression is an inline operation, so the reduced dump file size means a significant savings in disk space. Unlike operating system or file system compression utilities, Data Pump compression is fully inline on the import side as well, so there is no need to uncompress a dump file before importing it. The compressed dump file sets are automatically decompressed during import without any additional steps by the Database Ad ministrator. Data Guard Network Compression Data Guard provides the management, monitoring, and automation software infrastructure to create, maintain, and monitor one or more standby databases to protect enterprise data from failures, disasters, errors, and data corruptions. Data Guard maintains synchronization of primary and standby databases using redo data (the information required to recover a transaction). As transactions occur in the primary database, redo data is generated and written to the local redo log files. Data Guard Redo Transport Services are used to transfer this redo data to the standby site(s). With Advanced Compression, redo data may be transmitted in a compressed format to reduce the network bandwidth in an efficient way. Redo trans port compression is no longer limited to compressing redo data only when a redo gap is being resolved. When compression is enabled for a destination, all redo data sent to that destination is compressed. • Empty database objects will not consume any disk space • Very important for SAP environments as 60-70% of all tables, LOBs, indexes and partitions in a SAP installation are empty • Makes database installation for SAP a lot faster because creation of empty tables, LOBs, and indexes are dramatically faster • Oracle Data Dictionary Space queries run substantially faster Enhanced Add COLUMN Functionality Before Oracle Database 11g adding new columns with DEFAULT values and NOT NULL constraint required both an exclusive lock on the table and the default value to be stored in all existing records. Now in Oracle Database 11g, the database can opti mize the resource usage and storage requirements for this operation, default values of columns are maintai ned in the data dictionary for columns specified as NOT NULL. Adding new columns with DEFAULT values and NOT NULL constraint no longer requires the default value to be stored in all existing records. This not only enables a schema modification in subseconds and independent of the existing data volume, it also consumes no space. Especially for large tables, updating table column results in reduced execution time and space saving. Because ADD column is very common within SAP BW applications and SAP upgrades, enhanced ADD Column Functionality leads to: • Factor 10-20 performance improvement for SAP BW during ADD column process • Saving large amount of disk space Compared to Oracle Database 10g, the listed Oracle Database 11g features give the following results: Deferred Segment Creation Beginning in Oracle Database 11g Release 2, when creating a table in a locally managed tablespace, table segment creation is deferred until the first row is in serted. In addition, creation of segments is deferred for any LOB columns of the table, any indexes created implicitly as part of table creation, and any indexes subsequently explicitly created on the table. The advantages of this space allocation method for customers running Oracle database underneath their SAP applications are the following: Without Compression With Compression and other space optimizations Space Savings SAP ECC 6.0 SAP BW 7.0 SAP CRM 7.0 4,782 GB 1,413 GB 950 GB 1,976 GB 543 GB 334 GB 59% 62% 64% RMAN Backup (for compressed database) 2,817 GB 667 GB 76% 973 GB 156 GB 84% Database (fully reorganized) Export Data Pump Oracle Database 11g Release 2 for SAP SecureFile Performance Additional Encryption SecureFiles offer the best solution for storing file content, such as images, audio, video, PDFs, and spreadsheets. Traditionally, relational data is stored in a database, while unstructured content—both semi-structured and unstructured—is stored as files in file systems. SecureFiles is a major paradigm shift in the choice of files storage. SecureFiles is specifically engineered to deliver high performance for file data comparable to that of traditional file systems, while retaining the advantages of the Oracle Database. SecureFiles offers the best database and file system architecture attributes for storing unstructured content. Advanced Security Option (ASO) within Oracle Data base 11g includes RMAN Backup Encryption, so no one can read data from a (stolen) backup. In addition customers can easily encrypt export file with Oracle Data Pump unstructured LOB data with SecureFile Encryption. Overall transaction throughput increases when LOB data is stored in SecureFiles (see figure beside). LOB data stored in SecureFiles delivers equal or better per formance compared with LOB data stored in LONG or BasicFiles (LOB implementation prior to Oracle Database 11g). SecureFiles improve dramatically the scalability of SAP applications running against Oracle Database 11g RAC but also Oracle Database 11g Single Instance benefits substantially from SecureFiles. Therefore, a clear recommendation is given to migrate all existing LONG and Basicfile LOB data to SecureFiles. Data Guard provides a secure environment and prevents tampering with redo data as it is being transferred to the standby database. To enable secure transmission of redo data, set up every database in the Data Guard configuration to use a password file, and set the password for the SYS user identically on every system. More Security – Database Vault Oracle Database Vault is also certified for use with SAP applications. With Oracle Database Vault, protective realms around SAP application database objects can be established to prevent privileged database users from accessing sensitive data and to enforce separation of duties among privileged database users. SAP VBDATA Throughput (Insert/Read/Delete) Performance Improvement Factor SAP customers benefit from SecureFiles because of: • Significantly faster access times compared to LOBs in SAP environments • Increased transaction throughput on SAP cluster tables especially with RAC • Prerequisite for compression of SAP tables containing LOBs (e.g. cluster tables) DG Secure Network Transport g row size in KB Tablespace Encryption LONGs (9.2,10.2) On many agendas, security is in the forefront and becoming much more important for customers. Oracle has a lot of features in the area of security. Especially for SAP customers, it is now very easy to encrypt sensitive data. Included within the Advanced Security Option (ASO) is the technology to encrypt all data in a tablespace. Prior to Oracle Database 11g, Oracle provided security features such as Column Encryption through Transparent Data Encryption (TDE) and Client Server (SAP Application Server) Network Encryption. LOBs (10.2,11.2) Securefiles 11.2 BR*Tools Support for Oracle Database 11g As of version 7.20, BR*Tools support the new features provided by Oracle Database 11g Release 2 which makes it very easy to implement them even in existing systems (see SAP Note 1430669). In particular, the following operations are possible: • BRSPACE provides special options for online reorganization, which allow you to activate the new OLTP table compression 55 56 • To convert the “old LOBs” (data type LONG or LOB) to the “new LOBs” (data type SecureFiles), BRSPACE provides a new action “lob2lob” within the reorganization function “tbreorg” • As of patch 3, BRSPACE 7.20 supports the management of the index compression for Oracle Database 10g as well as Oracle Database 11g (see SAP Note 1464156) • BRSPACE allows you to set the compression and encryption attributes at tablespace level when you create a new tablespace. Tables that are created in (or moved to) such a tablespace then implicitly adopt these attributes, except if they are set explicitly at table level • BRSPACE is aware of columns which contain data that are compressed by SAP. It makes sure that the useless overhead of an additional compression is avoided Real Application Testing (RAT) • Database Replay provides DBAs and system administrators with the ability to faithfully, accurately and realistically rerun actual production workloads, including online user and batch work loads, in test environments. By capturing the full database workload from production systems, including all concurrency, dependencies and timing, database Replay enables you to realistically test system changes by essentially recreating production workloads on the test system, something that a set of scripts can never duplicate. With database Replay, DBAs and system administrators can test: Database upgrades, patches, parameter, schema changes, etc. • Configuration changes such as conversion from a single instance to Oracle RAC, Oracle ASM, etc. • Storage, network, interconnect changes • Operating system, hardware migrations, patches, upgrades, parameter changes statistics by running the SQL statements serially before and after the changes • SQL Performance Analyzer (SPA) can predict and prevent SQL execution performance problems caused by environment changes. SQL Performance Analyzer provides a granular view of the impact of environment changes on SQL execution plans and statistics by running the SQL statements serially before and after the changes The Oracle/SAP Development Team recently con cluded comprehensive testing of SAP applications using Real Application Testing to measure the effects of Advanced Compression for OLTP and SecureFiles on DML operations for SAP ERP. The testing activity consisted of using Database Replay to capture a pro duction workload from a Oracle Database Rel. 10.2.0.4 SAP database. This workload was then replayed multiple times against both compressed and noncompressed Oracle Database 11g Release 2 databases. The test results can be read in the newsletter http://www.oracle.com/us/solutions/volume19-en-183572.pdf on page 12. Direct NFS With Oracle Database 11g Release 2, you can confi gure Oracle Database to access NAS devices directly using Oracle Direct NFS Client, rather than using the operating system kernel NFS client. Oracle Database will access files stored on the NFS server directly through the integrated Direct NFS Client eliminating the overhead imposed by the operating system kernel NFS. These files are also accessible via the operating system kernel NFS client thereby allo wing seamless administration. SAP customers can benefit from Direct NFS in the following way: • Improves throughput of NAS solutions such as NetApp • Up to 50% more database throughput in NAS environments with multiple NICs • Up to 20% CPU savings on database server • Works for Single Instance and Real Application Clusters (RAC) • Works for UNIX, Linux and Windows Platforms • Highly Available Network Solution • Faster, easier and more available than any OS or NAS based bonding or trunking solution • Direct NFS with NAS may provide higher throughput than traditional, more complex SAN solutions • Superior to any bonding solution – faster and easier • Better throughput than most SAN solutions Oracle Database 11g for SAP Release 2 D A T A B A S E Online Patching A regular RDBMS patch is comprised of one or more object files and/or libraries. Installing a regular patch requires shutting down the RDBMS instance, relink ing the Oracle binary, and restarting the instance; uninstalling a regular patch requires the same steps. With Oracle Database 11g, it is possible to install single or bundle patches completely online, without requiring the database instance to be shut down, and without requiring RAC or Data Guard configurations. With online patching, which is integrated with OPatch, each process associated with the instance checks for patched code at a safe execution point, and then copies the code into its process space. Snapshot Standby Easy conversion of a physical standby database to a reporting database – A physical standby database can be opened read/write for reporting purposes, and then flashed back to a point in the past to be easily converted back to a physical standby database. At this point, Data Guard automatically synchronizes the standby database with the primary database. This allows the physical standby database to be utilized for read/write reporting activities for SAP applications e.g. NetWeaver BI. Out-of-place Upgrade Starting with the first patch set for Oracle Database 11g Release 2 (184.108.40.206), Oracle Database patch sets are full installations of the Oracle Database software. In past releases, Oracle Database patch sets consisted of a set of files that replaced files in an existing Oracle home. Beginning with Oracle Database 11g Release 2, patch sets are full installations that replace existing installations. This is Oracle’s recommended way to apply a patch set. You install the patch set into a new, separate Oracle home location. After you install the patch upgrade, you then migrate the Oracle Database from the older Oracle home. The patch set upgrade is now the same process to upgrade from one version to another. Oracle recommends that you perform an out-of-place patch set upgrade, because this patch set application option requires much less downtime, and is safer because it does not require patching an ORACLE_HOME that is already being used in production. However, you must ensure that you have sufficient free disk space to accommodate two Oracle home directories at the same time (for more information check SAP note 1524205). SAP Bundle Patches (SBP) Oracle database patches for UNIX-platforms are now delivered in form of so-called SAP Bundle Patches (SBP) as of Oracle Database Rel. 10.2.0.4. SBPs are based on Oracle Patch Set Updates (PSUs) that are proactive cumulative patches containing recommen ded bug fixes and Critical Patch Updates (CPU) that are released on a regular and predictable schedule. A SAP Bundle Patch consists of Current Patch Set Update (PSU), SAP specific necessary Single-and Merge-Patches which are not contained in the PSU, current SAP specific Optimizer-Merge-Patch, README.html: installation manual for SBP, bugs_fixed.html: list of patches contained in SBP. SBPs are cumulative and the current one contain all previous patches and then nes patches in addition. In other words, customers always need to install only one, the most current, SBP using MOPatch. Oracle Database 12c for SAP customers directions Oracle Database 12c will support SAP applications. More details will be available in the SAP Product Availability Matrix (PAM) Currently we are testing – among others: Oracle Database 12c options and features for SAP. • Multitenant Option • Information Life Cycle Management/Automatic Data Optimization (ADO), requires Advanced Compression Option (ACO) • Hybrid Columnar Compression (HCC) 57 57 11g 58 A N E W H O M E F O R Y O U R D ATA O R A C L E D ATA B A S E M I G R AT I O N T E C H N O L O G I E S Summary The term “database migration” can mean different things in SAP environments. On the one hand, you may want to keep the hardware as well as the opera ting system of your database server machine, but replace the database provided by vendor X with that provided by vendor Y. This is what SAP calls a hete rogeneous copy, and this is not what we want to dis cuss in this article. On the other hand, you may want to upgrade your existing hardware and/or change the operating system of your database server machine, but keep the database. Copying the existing database from legacy hardware to a new Exadata machine is one, but not the only example why you may need to perform such an operation. This is what SAP calls a homogeneous copy, and this is preci sely the subject of the following dis cussions. Even if it is clear that “migration” is to be understood in the sense of “homo geneous copy”, there are still several options and therefore many decisions to be taken. The most important one is related to this question: If you move to a new house, do you really put all your effort into building an exact copy of the old one, or do you rather try to avoid your previous mistakes and con struct a better one? That is why part I of this article discusses the difference between a migration strategy based on file copies (reproduction of the old house) and a strategy based on data export and import (construction of a new and more comfortable home). will change Oracle’s behavior as far as new data are concerned, but will not have any effect on existing data. However, a migration based on data export and import is precisely a database reorganization. So why not bundle the activities? Why perform two, three or four reorganizations, if one is sufficient? Part III, finally, explains yet another choice to be made. The strategy based on data export and import comes in two main flavors. One is called offline migration, which means that the Oracle database (and therefore the whole SAP system) is down while the migration is performed. The other one is called online migration. It is more complex. But it requires almost no downtime, even if your database is a very large one. Figure 1a: Database migration using a method based on operating system files. The database is not reorganized, and it needs to be prepared for use of new features after migration. Figure 1b: Database migration using a method based on database objects. The database is reorganized implicitly, and it can be configured for immediate use of new features. Part II presents compression, partitioning, and en cryption as optional Oracle features that can help build a better home – one that is more comfortable for the data as well as for the administrator. What these features have in common is the need to reorga nize existing data. Whether you just switch on com pression, or partitioning, or encryption, these features Part I: Database Migration in Context SAP System Copies As “migration” is such a fuzzy word, SAP prefers the term “system copy”. Whatever the goal of your pro ject is, and whichever method you choose – somehow you copy the data from a source database to a desti nation database. As, in this context, we are not O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s interested in modifications of the hardware and/or the operating system used to run the SAP applicati ons, it can be said that a heterogeneous system copy is a migration that moves the data from a database provided by one vendor to a database provided by a different vendor, whereas in the case of a homogeneous system copy the database vendor remains the same, but the data are moved to a different hardware/operating system platform. As stated in the summary, this article discusses only strategies for homogeneous system copies. But there is yet another distinction to be made, be cause there are two kinds of system copies. In the first case, your plan is to run two independent SAP on Oracle systems in the future. To accomplish this, you create a copy of an existing Oracle database, start a new SAP instance and connect it to the new database, but nevertheless you keep the old system up and running. A typical example for this procedure is the creation of a test or training system in addition to (but based on) the existing production system. In other words, this kind of system copy means database cloning. In the second case, the idea is to create a copy of the database and make it part of a new SAP system, but to stop the old system as soon as it is clear that the new system runs without issues. Only this can be called migration. The distinction between cloning and migration is important. If you need a clone, you need an exact copy of the database. There is no point in optimizing the test database (unless you want to test possible opti mizations). However, the very goal of a migration (e.g. migration to a new hardware platform) is improve ment (e.g. performance improvement), and therefore optimization of the database can help achieve even better results. Database Migration Options From an operating system perspective, a database is nothing but a set of files. Therefore the simplest migration strategy would be to copy those files from the source to the target storage using operating system commands. However, this approach has severe limitations. First, operating system and file system must be the same on source and target system. Second, this operation can only be performed, if the Oracle database (and therefore the SAP system) is down. If Oracle Recovery Manager (RMAN) is used in combination with the file copy approach, additional migration options are available. The first additional option is based on Oracle’s Transportable Tablespace technology. The basic steps are: (1) Create a new database consisting of all tablespaces that the database system itself needs (SYSTEM, SYSAUX, UNDO, TEMP). This is going to be the target database. (2) Use RMAN‘s data file conversion feature to copy (file system to Oracle ASM) and convert (big endian to little endian) all data files from all tablespaces that contain SAP-owned objects. (3) Plug-in the trans ported tablespaces into the newly created database. – As in this approach RMAN converts the data files according to the target requirements, the benefit is that source and target database can run on different operating systems and storage platforms. The dis advantage however is that it requires system down time. The second migration option that RMAN adds to a simple file copy is known as duplicate from active data base, because it is based on RMAN’s DUPLICATE DATABASE command. As the name suggests, this operation can be performed, even if the source data base is up and running, which is certainly its most important benefit. From an operating system perspec tive, source and target are not required to be identical, however the supported combinations of source and target platforms are somewhat more limited than in the transportable tablespace case. (For details see the Oracle white paper “Moving your SAP Database to Oracle Automatic Storage Management 11g Release 2. A Best Practices Guide”). An additional requirement is that source and target database must be on Oracle Database version 220.127.116.11 or higher. All this means that you have several options to choose from. Nevertheless, all strategies based on the file copy approach have one disadvantage in common: File copy does not change the structure of the files. File copy (with or without RMAN) copies all data from source to destination, and that is what you want it to do. But file copy copies the problems and issues as well. If your database files are fragmented, i.e. contain many small and empty fragments, because rows had been deleted or archived and the database has not been reorganized for a long time, then the new file (the file copied to the target system) has the same old fragmentation problem (see figure 1a). To 59 60 Figure 2a: Typical Oracle database used for SAP ERP (uncompressed). Figure 2b: Implementation of Oracle Index Key Compression. come back to the comparison already used in the summary: If in your old home you had a broken chair and a dirty wall, you start with a broken chair and a dirty wall in your new home as well. Two major benefits of this approach are obvious: (1) As the data transport relies on a database-to-data base communication, it is completely independent of the underlying operating system and storage plat forms. Any combination of source and target platform is possible. (2) As data are inserted into empty tables and indexes are recreated, the database is implicitly optimized. It is not uncommon that the target data base needs 20-25% less disk space than the source database. That is exactly why there is yet another, completely different migration approach. If, from en operating system perspective, the database is just a set of files, from a database perspective it is a set of database objects (mainly tables and indexes) containing data. On the database level, therefore, it is possible to provide tools that do not copy files, but data. Generally speaking, such a process consists of four main steps: • A new, empty database (the target database) is created. This time, however, the new database does not only consist of those tablespaces that are required by the database system. All user tablespaces (in this case: all tablespaces for SAP data) are created as well. The new tablespace structure may or may not be equal to the old one. • All tables are created (as empty tables) in the new database. This can be done, even in large databases with many tables, by generating SQL scripts in the source database and then running them in the target database. • The data are moved from the source tables to the target tables. • Finally the required indexes are created in the target database. However, there is a third benefit. You can really build a new home for your data, with a different room struc ture, different furniture, and walls painted differently. This means: In the new database, you can make use of Oracle features that you had not been implemented in the old database (see figure 1b). And you can make use of them immediately. One example is data compression. Whereas, if you rely on the file copy approach, you need to copy the files first and then implement compression, the export/import approach allows you to combine everything in one single step. Because data that had been exported from an uncom pressed database can be directly imported into a compressed database, you just create tables and in dexes in the target database with the COMPRESS flag – and that’s it. O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s Figure 2c: Implementation of Oracle OLTP Table Compression for structured table data. Figure 2d: Implementation of Oracle SecureFiles Compression for unstructured table data. As in the file copy case, there are several ways to make this strategy happen. Especially for SAP on Oracle environments, Oracle provides two methods. One is called Oracle to Oracle (“O2O” or “O2O Classic”), the other one Oracle to Oracle Online (“Triple O”) database migration. Both are much more than just a combination of data export and import. They rely on a combination of technologies that make them as fast, flexible, and reliable as possible. As their names sug gest, the main difference is that O2O requires the system to be shut down as long as the migration takes, whereas Triple O needs almost no downtime. Details are discussed in part III of this article. Triple O rebuild the database anyway, it makes sense to consider, whether or not you want to combine migration and compression in one single step. Part II: Optional Database Features If you decide to rely on an export/import-based migration approach (O2O or Triple O) instead of a file-copy-based approach, you can configure the tar get database for immediate use of new Oracle fea tures. But which features should you consider? Generally speaking: all features that require a data base reorganization. If you want to change, say the parallelism used to access data, that changes the way how Oracle works with the data (in this case: the number of processes), but not the data themselves. But if you want to compress your data (and that means: new as well as existing data), you need to rebuild tables and indexes. And because O2O and But there are more Oracle features that require a re organization of all or some database objects. In SAP environments, the most important ones are partitio ning and encryption. Therefore part II of this article discusses compression, partitioning and encryption in SAP environments. Can you combine migration, compression, partitio ning, and encryption in one single step? Yes, you can. Do you really want to do this? Well, it is up to you to make this decision. All Oracle can do and has done is to give you the flexibility, so you really have a choice and you can make a decision. You can do it in one step, or in four steps, or do something in between. Compression What is simply called “compression”, is actually a comprehensive set of compression capabilities. Not all of them are relevant for database migration pro jects. Those that are, are index and table data com pression. Figure 2 shows a typical implementation strategy, based on an Oracle database that is part of an SAP ERP system. 33% of the allocated disk space are used for indexes, 67% are used for tables, and the table data must be divided into structured and unstructured data (see figure 2a). 61 62 For historical reasons most customers start, and SAP still recommends to start with Index Key Compres sion, if compression is implemented in an existing database. In migration projects based on O2O or Triple O however, the sequence must be changed, as indexes are created after tables. Index Key Compres sion saves disk space by eliminating repeating values in the leaf blocks of B*Tree indexes (see figure 2b). Bitmap indexes, used in SAP BW, are already “com pressed”, so they cannot be compressed again. The term “structured table data” means that infor mation which consists of several items (e.g. first name, last name, city, zip code, etc.) is stored in separate table columns. Therefore the different items can be recognized by database tools such as SQL*Plus. Structured table data can be compressed using Oracle’s Table Compression, which – again for historical rea sons – is also called OLTP Data Compression. This does not mean that only data used in OLTP (e.g. SAP ERP) systems can be compressed. Exactly the op posite: It means that, unlike its predecessor (data compression in Oracle Database 10g), data compres sion in Oracle Database 11g cannot only be imple mented in OLAP systems (e.g. SAP BW), but in OLTP systems as well. Leaving aside history, OLTP Table Compression can be implemented in all SAP systems. Similar to Index Key Compression, Table Data Compression saves disk space by eliminating repeating values (see figure 2c). The term “unstructured table data”, then, means that information which consists of several items is not stored in separate table columns, but in one single column only. A typical example would be a PDF file stored in a database table. Unstructured data occur in SAP systems as well, because SAP applications sometimes bundle data sets and store them as one single value, which means that SAP applications can recognize the individual items, but the Oracle data base and Oracle tools cannot. In Oracle Database versions prior to 11g these data had been stored in LONG or LOB columns. However, LONG as well as LOB values cannot be compressed. Therefore Oracle Database 11g comes with a new data type, called SecureFiles, which can be compressed, and that is why compression of unstructured table data is called SecureFiles Compression. Strictly speaking, this is the only case of compression, as Index Key and OLTP Data Compression just store data in a different (more efficient) format, whereas SecureFiles Compression is similar to what a ZIP utility does (see figure 2d). Lab tests and customer results prove that by combi ning these three compression capabilities the disk space needed for your database can be reduced by 50% or more. This comparison assumes that the database was completely reorganized before compression. If the source database is fragmented, disk space savings will be considerably higher. Lab tests and customer results also show that – con trary to most expectations – compression has no negative impact on database performance. Again the opposite is true: In most cases customers have seen performance improvements, as compression reduces I/O and improves the buffer hit ratio (SGA). Partitioning The basic idea of partitioning is very simple: group rows of a “table” based on the value(s) in one (or more) column(s) and store the distinct groups as “sub-tables” (see figure 3). That rows can be grouped “based on the value(s)” in one or more column(s) is a very generic statement. Oracle provides many possible strategies to do exactly that. The strategies which are most important in SAP environments are called list and range partitioning. Figure 3: Oracle table and index partitioning. O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s Table 1: Oracle table/index partitioning and SAP applications In order to implement list partitioning, a list of values has to be established which explicitly mentions every single value (example: countries, locations). In order to implement range partitioning, it is sufficient to define ranges by stating a start and end (example: January 1-31, February 1-28, etc.). Oracle does not only support table partitioning, but also index partitioning. So database designers can group the rows in a table or the entries in index (leaf) blocks and store the results as virtual subsets called “partitions.” Nevertheless, the table or the index can still be accessed as one single object, if this is neces sary. Depending on application needs, an index on a table can be partitioned (“local index”), but can as well remain unpartitioned (“global index”). If multiple indexes on a table exist – a situation which is rather normal in SAP systems–, some of them can be local, some global. The main benefit of table and index partitioning for users is improved performance. The technical reason for this performance improvement is called “partition pruning”. Let us suppose a table partitioned by month and an application that wants to generate a monthly report based on this table. Receiving the request, the Oracle database will immediately realize that all partitions which need to be considered are located in one single partition, and therefore it will scan this partition only. This reduces I/O, memory usage and CPU workload dramatically, and therefore customers almost always see a performance improvement by a factor of 5, 10, or even more. The main benefit for administrators is the fact that partitions can be managed individually and indepen dently. If a table consists of 90% historical and 10% active data, and if partitioning was used to separate historical and active data, it is rather likely that ad ministrative procedures such as daily backup or reorganization can be restricted to the partitions containing active data, whereas procedures such as archiving can be performed on very few historical partitions. This reduces unnecessary workload as well as the time needed for these jobs. Moreover, partitions can be created, dropped, or merged inde pendently and online, so no additional maintenance downtime is required Many years ago, SAP realized the benefits, and in particular the performance improvements provided by table and index partitioning. Therefore, Oracle Partitioning is supported by SAP for SAP BW systems as well as OLTP systems such as SAP ERP (see table 1). However, there is a difference. For SAP BW, Oracle 63 64 However, with SAP ERP databases reaching a size of 10, 20 or 30 Terabytes (in some cases even more) and 90% of the data located in a handful of giant tables, there was an urgent need for a solution. This solution, which was developed over several years, consists of 2 parts: a partitioning method provided by Oracle and a management interface provided by SAP, which is called the “SAP Partitioning Engine.” Figure 4: Unencrypted tablespace, use of column encryption, and use of tablespace encryption. However, there is a difference. For SAP BW, Oracle Partitioning is not only supported, but also imple mented. This means that the questions as to which tables should be partitioned and how, are already answered by SAP, that partitioning is implemented during the installation and configuration process, and that partition management tools are provided by SAP. This can be done, because the answer to the question, which tables should be partitioned and how, is the same for all SAP BW systems. In contrast, Oracle Partitioning for SAP ERP is supported, but there is no default implementation provided by SAP. It is easy now, to guess the reason: the answer to the question which tables should be partitioned and how is not the same for all customers and all systems. Figure 5: Column encryption and data access Figure 6: Tablespace encryption and data access However, in Oracle to Oracle migration projects the SAP Partitioning Engine is not needed. O2O and Triple O are actually more flexible and more powerful. They can generate customized migration scripts which create partitioned tables and indexes in the target database. They do not only support range partitioning, but also list partitioning (based on the column “MANDT”). And they provide enhanced partitioning support (e.g. subpartitioning). Encryption Oracle provides many security features which can be used in SAP environments (for an overview see the article “Oracle Database Security for SAP Applica tions” in this volume). Most of them (Database Vault, Network as well as Backup Encryption) can be im plemented without changes to the data in the data base, i.e. without the need to rebuild tables and indexes. The only exception is Transparent Data Encryption, a feature designed to encrypt data in the production database. Transparent Data Encryption comes in two flavors. The first one, which had already been available in Oracle Database 10g, is called Column Encryption, because you select just a few of the many SAP tables, or even individual columns of these tables that contain sensitive data and encrypt them. Everything else re mains unencrypted. The second one, called Tablespace Encryption, is new in Oracle Database 11g. It allows you to encrypt complete tablespaces, which may contain hundreds, thousands, or tens of thousands of tables – you don’t care (see figure 4). This sounds as if the difference between these two encryption types was just the number of tables or the amount of data to be encrypted. The reality is that column encryption and tablespace encryption are based on completely different approaches (see figures 5 and 6). O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s Figure 7: Oracle to Oracle ("O2O") database migration technology overview If column encryption is used, database blocks that contain at least some encrypted data are transferred to the database cache (SGA) and stored in the cache in exactly the same format as on disk. This means that applications that want to read those data can find them in the SGA, but still in encrypted format. And this, in turn, means that every single application (or rather every single Oracle server process receiving a read request from an application) needs to decrypt the data. Time and again. It is clear that this causes a certain CPU overhead and slows down the system, unless only very few columns had been selected for encryption and are accessed rarely. Tablespace encryption is based on the idea that the goal of encryption is to prevent attackers from reading database using some kind of editor. As long as data are stored on disks or tapes, they are unsecure, because disks and tapes can be stolen. However, when they enter the database server, they are protected, because the database server machine is like a castle or a town protected by a wall. Therefore it is sufficient to decrypt data once, when they enter the machine (i.e. when they are read from disk and before they are stored in memory), and encrypt them again, when they leave the machine (i.e. when they are written to disk). All applications, then, find unencrypted data in the SGA and can immediately work with them. Considering that a physical read operation can be followed by tens, hundreds, or even thousands of inmemory accesses by applications, it is clear that this new approach reduces CPU overhead and negative performance impacts dramatically. That the hardware encryption feature provided by some of the recent CPUs can be used for tablespace encryption (but not for column encryption), is an additional plus. It means that tablespace encryption finally comes with almost no CPU overhead. Part III: Oracle to Oracle Migration Methods Oracle-to-Oracle Offline ("O2O”) Migration Method The O2O database migration method was developed by Oracle ACS services, to offer customers, having a very large database, a fast, smooth and reliable migra tion method. This method offers a migration speed of more than 1 TB/hour and reduces the efforts which must be spent for configuring and testing of the migration. O2O supports all operating systems on which SAP products are certified. Because O2O is operating sys tem independent, it can be used to perform homoge nous and heterogeneous system copies. 65 66 The advantage of this method is that, you can com bine the operating system change with multiple options to get the most out of the migration: • With O2O it is possible to combine a platform migration with a release upgrade. The migration method supports every combination of Unix, Windows or Linux on the source and target system. So, you can migrate an existing Oracle 10.2 data base on HP-UX to an Exadata Solaris database • It is possible to upgrade directly to a higher data base release. Currently with the O2O method direct database migrations are possible between different Oracle versions. So it is possible to up grade directly from Oracle 9i to Oracle 11g by using O2O. You also do not need the most current patch set of the lower Oracle release to run the migration • As part of the database migration, the whole data base is reorganized. This can free up a significant amount of space within tables and indexes • The tablespace layout can be changed to the new SAP standard or to a customer’s customized one. It is also possible to move single tables and indexes to separate tablespaces or to merge them into existing or new ones. This allows you to unify the SAP landscape by using a default tablespace name like “PSAPSR3” in all SAP systems • The SAP schema name can be changed, for instance to “SAPSR3”, to unify the SAP landscape • The number of data files and mount points can be significantly reduced, by either optimizing the tablespace layout or the size of the data files and file systems. • Tablespaces are created with LMTS and ASSM. • The method creates the appropriate scripts to create either a database using normal files systems or a database using ASM or Exadata file systems • Data files will be converted from file system to Oracle ASM. The method provides you with the needed scripts to create the database and the tablespaces automatically • LOB or LONG data types can be converted to SecureFiles (11.2 only). SecureFiles will also be compressed, if possible. • You can compress the indexes on the target data base by using Oracle index compression. The compression calculation is executed as described in SAP Note 1109743. The correct index compres sion for each index is determined automatically. • You can compress tables on the target system. The compression will compress all SAP tables as recommended in SAP Note 1431296. The downtime needed to migrate a database with the O2O method is dependent on the database size, the included database objects (SAP cluster tables, partitioned tables) and the available hardware resources (CPU, Memory, Storage, Network). Up to 1TB/hour is possible. Although O2O was originally developed to perform database migrations, it can be an interesting method to perform a simple database upgrade, because you can implement all new database features you want into a single step: • Database upgrade directly from 9i or 10g to 11g. There is no need for a special database release on the source, which can save additional time, because you don’t need to patch the current database re lease before you perform the upgrade. • Reorganization of the complete database to free up unused space. • Implementation of index and table compression, which will result in a 50% smaller database size. O2O Technology The O2O method is based on the following steps: (see figure 7) 1. Prepare the source system, by defining the needed Oracle directories on the file system and load the into the source system. To hold the scripts on the file system, only a few MB are needed, typically less than 50 MB. 2. Define the basic conditions for the migration, e.g. definition of the setup for the target database (ASM configuration, usage of table and index compres sion, or other database features). The PL/SQL package is then executed to generate the needed migration scripts. A typical package run will take 30 – 60 minutes on a SAP system. O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s 3. Creation of an empty target database, either with the provided scripts generated by the PL/SQL package or with your own scripts 4. After the scripts are created they are copied to the target system, to run the database migration itself. To run the migration process a program named “scheduler” is available, which runs all needed migration scripts in the correct order and also controls the correct execution of each script. Using this scheduler you have full control over the migra tion. This includes the possibility to restart failed scripts or to set it to “Done”. The scheduler is written in ksh and runs on all Unix or Linux ope rating systems. It’s also possible to run the sche duling software on a remote machine, e.g. if Windows is used on source or target. The throughput depends on the available hard ware on the source and target machine. In best cases you can build up the target database with more than 1 TB/ hour. Typically the throughput will be on average between 250 GB/hour and 500 GB/hour. To achieve this throughput, different migration methods are used for the database tables. Based on the table size and datatype (e.g. SAP cluster tables), the best migration for the particular tables is chosen to achieve the best migration per formance. Typically most of the data is transferred directly over the network, not using a dumpfile for the migration. This saves space on the file system. To verify the migration, source and target databases are compared on object level (based on the object name) to ensure the correctness of the migration. In a second step, all tables on source and target are compared based on the number of rows. So at the end of the migration you can prove the cor rectness of the migration based on object and row level. 5. Once the migration is completed the post SAP migration tasks can be started. The systems are fully supported by SAP as mentioned in SAP note # 1508271 The O2O method is developed and maintained by the Oracle ACS service in Walldorf Germany. O2O is available either as an ACS service or can also be used directly by customers. Oracle-to-Oracle Online ("Triple O”) Migration Method If the downtime requirements cannot be fulfilled with the O2O offline method, you can use as an alternative the Triple-O method. The first step, estimate the downtime available for the technical database migra- Figure 8: Oracle to Oracle Online ("Triple O") database migration technology overview 67 68 tion. During this period of downtime not only the database migration must be performed, but in case of a heterogeneous system copy, user acceptance tests, interface tests and post-SAP migration tasks must be performed. As a result, the real available downtime for the technical database migration is much shorter than the application downtime. So the Triple-O method was developed to reduce the technical database migration time to a minimum. Typically the required downtime for the database migration is between 30-60 minutes, independent from the database size. On customer request the source and target database can be compared based on the row count after the migration is completed to ensure the correctness of the online migration. Triple-O Technology Triple-O Technology is a real online migration of the database. It uses GoldenGate software for the online synchronisation of the changes and modifies the O2O version, to perform a consistent initial database load. GoldenGate reads the online redo log or the archive log of the database and extracts DDL and DML changes, recorded in the redo log of the database. GoldenGate transforms the physical changes from the redo log file into a general description, which is operating system and database release independent, and saves these changes into trail files. The volume of the trail files is typically 30% - 50% of the redo log volume. To use GoldenGate supplemental logging must be enabled on the database. The GoldenGate trail files are sent to the target data base server, either with GoldenGate, using a network connection, or by providing the trail files via NFS to the target system. On the target side the trails files are read by apply processes, which execute native SQL statements, generated out of the contents of the trail file on the target system. So each DML is transformed into the appropriate insert, update or delete command. Also, allowing the use of GoldenGate for heterogene ous system copies as well. It’s possible to start or stop an online migration at any time. There is no downtime needed for the start or the stop of the migration. Furthermore the migration method doesn’t need any special database patches, nor a special database patch level. Triple-O runs on any 9i, 10g or 11g version and supports DML and DDL changes. So there are no limitations (e.g. transport stop) on the usage of the SAP system during the migration. All operations can be performed as usual. Both, R/3 and BW systems are fully supported. Because GoldenGate is operating system indepen dent, also heterogeneous database migrations are supported. The minimum Oracle release on the source is 9.2. Direct database upgrades to 10g and 11g are possible. When using Triple-O, you can make use of all features listed for the O2O method. So the basic configuration is very similar between O2O and Triple-O. Beside the migration scripts, for Triple-O, the GoldenGate configuration scripts will be generated automatically. The online migration is running in a very similar way, as the previously described O2O migration. A PL/SQL package is loaded into the database, and creates all necessary scripts, to perform the online migration. Instead of running the migration scripts offline (SAP is down), these scripts are now executed, while SAP is up and running. To allow a consistent export of the data, Oracle flashback capabilities are used. This allows on one side a consistent export of the tables to a specific SCN (System Change Number), on the other side it’s possible to configure the GoldenGate processes for each table to the table specific SCN, to guarantee an error free apply. The fetch of an indi vidual SCN for each table and the update of the GoldenGate configuration files is executed by the scheduler software, which runs the migration. One challenge in an online migration is handling the additional load generated by the GoldenGate processes and the initial data load. Very often the current hardware on the source system is outdated and already fully used by the current application load. So it’s not possible to add additional load on the system, without harming the production. To allow an online migration, even under these circum stances, it’s possible to run a downstream capture of the GoldenGate processes. In such a configuration the archive files from the production system are an alysed and extracted on a different server. This server is not required to have the same OS but only the same endian byte order. So it’s possible to process database archive files from HP-UX, AIX and Sun Solaris (big endian) and Linux, Windows (little endian) cross-platform. O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s Therefore it’s possible to run the GoldenGate proces ses on different hardware, to unload the productive environment and preserve the resources on the production system. If any conflicts exist handling the initial data unload on the productive system, a shadow database can be used instead. So it’s possible to run a Triple-o migra tion completely outside of the productive systems, which allows us to perform an online migration even on old and outdated hardware. GoldenGate can be configured in many different ways in order to support very large databases with a huge system load. To increase the capabilities to process a larger redo log volume, up to 34 GoldenGate processes can be defined. Each process gets a number of tables to extract the DML and DDL changes of these tables. The PL/SQL package will perform a load distribution, based on the recorded DML changes in the database for each table. It's possible to configure up to 34 processes for the redo log extraction. One GoldenGate extract process is capable of handling up to 1 TB of redo within 24 hours. In general, the apply on the target system requires more process than to extract the redo log file. Typi cally for a normal SAP system 5 – 10 apply processes are needed. For large BW systems more than 20 apply processes could be needed. To allow a maximum flexibility for the GoldenGate configuration, for each extract process up to 34 apply processes can be defined. Once again, the assigned tables in each extract are assigned to the number of defined apply processes by performing a work load balancing. So, with 2 tier architectures more than 1000 apply processes would be possible. The typical project plan for an online migration generally has the following phases (see figure 8): 1. Prepare the migration, generate migration scripts. 2. Start the GoldenGate processes to record the data base changes either on the productive system or downstream on a different server. The recorded changes, listed in the trail files are sent over the network to the target machine, where they are stored in the file system. 3. Run the SCN-based initial data load either from the productive server or from a shadow database. During the initial load the database changes are recorded permanently to the GoldenGate trail files. The duration of the initial load depends on the database size and the number of jobs which can be executed in parallel to unload the database. Typically the unload is completed within 48 hours. 4. Once the initial load is completed the apply pro cesses on the target machine are started. Because the apply couldn’t be started as long as the initial data load is running a time gap between the source and the target system will now exist, which must be closed to bring both systems into sync. 5. Now, there must be enough time to close the time gap between the source and target database. The needed time depends on the number of changes which have to apply, the kind of operations which have to be apply, the number of apply processes and the performance of the target system. 6. If the time gap between source and target system is closed, both systems can run in parallel up to the final switch. Typically an online migration starts 5 days before the final switch. But if needed the migration can start more than a week before, to have enough time for all needed activities. 69 70 O r a c l e D a t a b a s e M i g r a t i o n Te c h n o l o g i e s Triple-O for Datacenter Migration Very often systems must be transferred between data centres. This can be due to a data centre consolidation, or is needed when the provider is changed. In this case it’s very likely that there exists only a limited network connection between the database centres, which doesn’t provide the necessary band width to run the initial data load and the GoldenGate proces ses in parallel. To run a full database load over a net work at least a one Gigabyte connection is needed. For WAN connections typically 100 Megabit or even less is available. In this case it’s still possible to run a full online migration, with the above mentioned minimum downtime between 30-60 minutes. To achieve this, the following approach is used: 1. Prepare the migration, generate migration scripts 2. Start the GoldenGate processes to record the data base changes either on the productive system or downstream on a different server. The recorded changes, listed in the trail files are sent over the network to the target machine, where they are stored in the file system. To optimize the usage of the network band width, the GoldenGate transfer can be compressed by a factor of approximately 5-7. 3. Run the SCN-based initial data unload either from the productive server or from a shadow database. To save the band width the database is dumped out to a NAS server in multiple dump files. With a single NAS device you can achieve a throughput of 150 GB/h. 4. Once the initial unload is completed, the NAS device is detached from the source system and transported to the target data centre. 5. The NAS device is attached to the target system and the target database is loaded from the NAS device. 6. Once the initial load is completed, the applies on the target machine are started. 7. Now, there must be enough time to close the time gap between the source and target database. The time needed depends on the number of changes which have to be apply, the kind of operations which have to be applied, the number of apply processes and the performance of the target system. 8. If the time gap between the source and target system is closed, both systems can run in parallel up to the final switch. Using this approach it’s possible to migrate databases between date centres, which are connected only by a limited network connection. Using the enhanced configuration option for GoldenGate (downstream capturing, usage of a shadow database for the initial database load) even very large databases with very critical performance can be migra ted with a minimum downtime. The online migrations are performed without creating additional downtime during a larger migration project, so migration costs are reduced.

Together they deliver one solution for managing all business data, application binaries and personal data in a cloud infrastructure. Oracle customers will benefit from a single integrated solution instead of dealing with the complexities of managing different software layers from different vendors. It eliminates the need for 3rd party volume managers and file systems. Oracle Cloud File System that compliments Auto matic Storage Management for Oracle Databases is certified by SAP as of Oracle version 18.104.22.168 for Oracle Single Instance and Oracle Real Application Clusters (Oracle RAC). Starting with 11g (22.214.171.124) Oracle Cloud File System is the preferred storage platform for SAP systems running on Oracle Real Application Clusters (RAC), as well as SAP systems running on a single Oracle Database. SAP customers are now able to use Oracle Cloud File System to manage ALL data: Oracle Database files, Oracle Clusterware files and nonstructured general purpose data such as Oracle and SAP kernel binaries, external files, and text files. Oracle Cloud File System can help to reduce costs, minimize the administration effort, and increase the availability of the SAP systems of all those custo mers who have been using Oracle single instance and Oracle Real Application Clusters (RAC) for SAP on the various platforms and using the underlying shared cluster file systems, required by Oracle RAC. The Oracle Cloud File System comprises the follo wing features: Oracle Automatic Storage Manage ment Cluster File System and Oracle Automatic Storage Management Dynamic Volume Manager. These three main parts of Oracle Cloud File System create an integrated foundation for database and general purpose files as well as an infrastructure for cluster and single node server configurations. The Oracle Grid Infrastructure simplifies and streamlines management of volumes, file systems and cluster con figurations, therefore eliminating the need for multi ple 3rd party software layers, complexity and cost. Complexity and cost can be reduced enormously for SAP customers using Oracle RAC by using SAPCTL (SAP Control) starting by Oracle Database Rel. 10.2 Clusterware and higher, making SAP services highly available and eliminating the need of 3rd party soft ware. Overview of Automatic Storage Management (ASM) Oracle ASM is a volume manager and a file system for Oracle database files that supports single-instance Oracle Database and Oracle Real Application Clusters configurations. Oracle ASM is Oracle’s recommen ded storage management solution for SAP on Oracle RAC and Oracle single instance that provides an alternative to conventional volume managers, file systems, and raw devices. Oracle ASM lowers the Oracle database storage total cost of ownership and increases storage utilization while improving performance and availability over traditional file system and volume management so lutions. Oracle ASM is easier to manage than con ventional file systems, has the performance of raw volumes, and is tightly integrated with the Oracle Database forming the foundation of a storage grid for Oracle. Additionally, Oracle ASM eliminates the need for 3rd party volume managers and file systems for managing the Oracle database files. Oracle ASM uses disk groups to store data files; an Oracle ASM disk group is a collection of disks that Oracle ASM manages as a unit. Within a disk group, Oracle ASM exposes a file system interface for Oracle database files. The content of files that are stored in a Oracle Cloud File System for SAP disk group is evenly distributed to eliminate hot spots and to provide uniform performance across the disks. The performance is comparable to the performance of raw devices. You can add or remove disks from a disk group while a database continues to access files from the disk group. When you add or remove disks from a disk group, Oracle ASM automatically redistributes the file contents and eliminates the need for downtime when redistributing the content. Oracle ACFS can be accessed and managed using native operating system file system tools and standard application programming interfaces (APIs). Oracle ACFS can be configured and managed using Oracle Enterprise Management tools. Oracle ACFS can be accessed using industry standard Network Attached Storage (NAS) File Access Protocols: Network File System (NFS) and Common Internet File System (CIFS). The Oracle ASM volume manager functionality provides flexible server-based mirroring options. The Oracle ASM normal and high redundancy disk groups enable two-way and three-way mirroring respectively. Oracle ASM files can coexist with other storage management options such as raw disks and third-party file systems. This capability simplifies the integration of Oracle ASM into pre-existing environments. Overview of Oracle ASM Cluster File System (ACFS) Prior to Oracle Database 11g Release 2, Oracle ASM was a volume manager and a file system for Oracle database files only. Now, Oracle customers can bene fit from a single integrated solution instead of acting as the systems integrator and dealing with the com plexities of integrating different software layers from different vendors in house. Oracle ASM, Oracle ACFS, Oracle ADVM snapshot are tightly integrated with the Oracle Database, Oracle RAC, Clusterware and other Oracle technologies and presents a comprehen sive and well tested solution for SAP customers run ning the Oracle Database. Oracle Automatic Storage Management Cluster File System is a multi-platform, scalable file system, and storage management technology that extends Oracle Automatic Storage Management functionality to sup port customer files maintained outside of the Oracle Database. Oracle ACFS is tightly coupled with Oracle Clusterware technology, participating directly in Clusterware cluster membership state transitions and in Oracle Clusterware resource-based high availability (HA) management. In addition, Oracle installation, configuration, verification, and management tools have been updated to support Oracle ACFS. Figure 1 An Oracle ACFS file system is a layer on Oracle ASM and is configured with Oracle ASM storage, as shown in Figure 1. Oracle ACFS leverages Oracle ASM func tionality that enables: • Oracle ACFS dynamic file system resizing • Maximized performance through direct access to Oracle ASM disk group storage • Balanced distribution of Oracle ACFS across Oracle ASM disk group storage for increased I/O parallelism • Data reliability through Oracle ASM mirroring protection mechanisms Overview of Oracle ASM Dynamic Volume Manager (ADVM) Oracle ASM Dynamic Volume Manager (Oracle ADVM) provides volume management services and a standard disk device driver interface to clients. File systems and other disk-based applications send I/O requests to Oracle ADVM volume devices as they would to other storage devices on a vendor operating system. 73 74 Oracle Cloud File System for SAP Moving SAP databases to Oracle Database 11g Release 2 ASM SAP customers can now move their databases to ASM, the preferred storage platform for SAP systems run ning on RAC and single instance. Customers can migrate their current file systems to ASM/ACFS/ADVM in a smooth way based on the best practices published on http://www.oracle.com/sap, http://www.sdn.sap.com/irj/sdn/ora and SAP Note 1550133. Based on these white papers the migration can be briefly described as follow: An Oracle ADVM volume device is constructed from an Oracle ASM dynamic volume. One or more Oracle ADVM volume devices may be configured within each Oracle ASM disk group. The Oracle ADVM Driver maps I/O requests against an Oracle ADVM volume device to blocks in a corresponding Oracle ASM dynamic volume and disk set located within an Oracle ASM disk group. An Oracle ADVM volume device exports Oracle ASM volume manager features and ensures that volume mirrors remain consistent in the face of abnormal system shutdowns, Oracle ASM instance failures, or system failures. Oracle ADVM extends Oracle ASM by providing a disk driver interface to Oracle ASM storage allocated as Oracle ASM volume files. You can use Oracle ADVM to create virtual disks that contain file systems. These file systems contained on Oracle ASM volumes are able to support files beyond Oracle database files, such as executable files, report files, trace files, alert logs, and other application data files. Because Oracle ADVM volumes are actually Oracle ASM files, they require the same administrative privileges as the Oracle ASM files. Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is layered on Oracle ASM through the Oracle ADVM interface. With the ad dition of the Oracle ADVM, Oracle ASM becomes a complete storage solution of user data for both data base and non-database file needs. • Oracle ASM Disk Groups configuration • Oracle Grid Infrastructure installation • Oracle Database 11g Release 2 and first patch set (126.96.36.199) installation • Configuration of Source and Target system • Online database migration through RMAN using “duplicate from active database” in case the OS platform does not change or if the source and target system have the same ENDIAN • Off line database migration thorough RMAN using “transportable tablespaces” or export/import or Triple O based on Oracle GoldenGate if the platform changes (can also be used for homogeneous migra tion) • For more information about the migration process, check the white papers mentioned above BR*Tools support for Oracle ASM and Exadata SAP provides the tools BRBACKUP, BRARCHIVE, BRRESTORE, BRRECOVER, BRSPACE, BRCON NECT, and BRTOOLS to manage and protect the data in your Oracle database.

The effects of an unexpected problem could be widely felt and have serious consequences. For this reason, testing of changes prior to production deployment is con sidered critical. The cost involved in testing using traditional methods can be very high both in time and money. Even after testing, many problems will only be discovered in production, and as a result end-users will suffer from poor performance or possibly even outages. Oracle now has a new and unique testing tool for the Oracle Database called Real Application Testing. This Database option comprises of two complementary features, SQL Performance Analyzer (SPA) and Database Replay. Together, these features can help ensure that database changes do not neg atively impact SAP availability and performance. They significantly improve the quality and lower the cost of testing changes to the SAP database system. SQL Performance Analyzer (SPA) One of the key tasks for a DBA is to tune SQL statements for optimal performance. Changes to database systems (such as optimizer statistics refresh, database upgrades, and patches) can cause the performance of previously well tuned SQL statements to regress, which can dramatically impact system performance for end-users. Until now, it was difficult if not impossible to predict how day to day operational changes to the data base will impact application SQL performance. With SQL Performance Analyzer, or SPA, you can now know exactly how SQL will behave after routine system changes. SPA automatically captures production SQL state ments from your SAP database and re-executes them following a change to measure the impact. The statements are executed serially, in isolation from each other and regressed statements are auto matically highlighted. Integration with SQL Plan Management and SQL Tuning Advisor enables automatic tuning of these statements to address any regressions prior to a change being implemen ted in production. Orchestration of the entire SPA process can be done using Enterprise Manager, which provides a number of workflows for testing common operati ons such as Database Upgrades. There is also a Guided Workflow which enables custom experi ments to be conducted. 75 76 Real Application Testing was introduced in the 11g release of the Oracle Database, however, SQL Performance Analyzer is also available for previous releases of the Oracle Database. Consequently, SQL Performance Analyzer can be used to test changes in SAP environments even if there are no immediate plans to move to Oracle Database 11g Release 2. Some examples of changes that could be assessed using SQL Performance Analyzer in SAP environ ments are: • Upgrade SAP Database from Oracle Database 10g Release 2 to 11g Release 2 • Install Database Patchset • Migration from single instance to RAC • Implement Partitioning • Implement Advanced Compression • Changes to _FIX_CONTROLS parameter settings Technical White Paper: SQL Performance Analyzer Viewlet: SQL Performance Analyzer in Oracle Database 11g Oracle Database Real Application Testing User’s Guide Database Replay Load testing today is generally done using tools that allow testing teams to generate synthetic workloads based on what they expect users to do on a system. These workloads can then be replayed by application virtual users, which simulate the end users by submitting requests to the applica tion. Although widely used, this approach has a number of shortcomings when it comes to testing database level changes: • Creating the synthetic workload can take a considerable time and requires programming expertise • User behaviour is not well understood, so many possible workflows are often missed in the synthetic tests • Creation of Histograms on SAP tables • Production scale database concurrency is near impossible to simulate with these tools There are no SAP specific patches required to use SQL Performance Analyzer. Further general infor mation on using SQL Performance Analyzer can be found in the following documents: There are no SAP specific patches required to use SQL Performance Analyzer. Further general infor mation on using SQL Performance Analyzer can be found in the following documents: • A full application stack is required for testing as these tools simulate end users Database Replay makes it possible to capture a workload on a production system with negligible performance overhead and replay it on a test system with the exact timing, concurrency, and transaction characteristics of the original workload. R e a l A p p l i c a t i o n Te s t i n g f o r S A P Database Replay is suitable for testing changes to the database tier and anything below it, such as storage or OS platform. This also means that tiers such as the Web and Application Server tier are not required in the test environment. The Database Replay capture process has been backported and certified for SAP databases running on Oracle Database 10g Release 2 (10.2.0.4). Changes that Database Replay could be used to validate include: • SAP Database upgrade from 10gR2 (10.2.0.4) to 11gR2 • Platform migration such as from Windows to Oracle Solaris • Database Patchset install • Changes to _FIX_CONTROLS parameter settings • Schema changes Results of Testing The Oracle/SAP Development Team recently con cluded comprehensive testing of SAP applications using both SQL Performance Analyzer and Data base Replay. The testing consisted of SAP R/3 and BW workloads running in-house on the ABAP stack. Further testing was undertaken at a large utilities customer running the SAP IS-U (Industry Specific Utilities) module. The objective was to use Real Application Testing to measure the effects of Advanced Compression for OLTP and SecureFiles on DML operations for SAP R/3. The testing activity consisted of using Database Replay to capture a production workload from a 10.2.0.4 SAP database.

The company is the undisputed leader in major markets such as Italy, the UK, and Russia. Founded in 1975 and listed on the Milan stock exchange since 1987, the Group posted sales of € 2.8 billion in 2011. Indesit Company has 14 production facilities (in Italy, Poland, the UK, Russia and Turkey) and 16,000 employees. The Group’s main brands are Indesit, Hotpoint and Scholtès. Indesit Company, a leading European manu facturer of household appliances, originally opted for Oracle Database and SAP over 10 years ago. The combination proved to be a stable, reliable and powerful basic infrastruc ture component. With every new release, Indesit expanded its capabilities – for example during the change from Oracle Database 9i to Oracle Database 10g and also from 10g to Oracle Database 11g. Laura Benedetti from Indesit’s Information Technology / Application Infrastructure team says, “We have always benefited from the combination of SAP and Oracle. With Oracle Database 11g and the Advanced Compression feature we have achieved considerable cost savings and optimized the whole SAP IT infrastructure very effectively.” Improvements and optimizations deliver major benefits Indesit first decided to implement long-term space savings and thus long-term cost savings with Oracle Advanced Compression techno logy before the switch from 10g to 11g. As soon as Oracle Database 11g appeared on the horizon, Indesit first decided to implement long-term space savings and thus long-term cost savings with Oracle Advanced Compres sion technology before the switch from 10g to 11g. As soon as Oracle Database 11g appeared on the horizon, the company was enthusiastic about the improvements that could be achie ved with the technology. Indesit decided not to make Advanced Compression productive during the migration in 2011, but was eager to achieve this as soon as circumstances allowed after the upgrade. Oracle Advanced Compression at Indesit Once the database migration was complete, the Application Infrastructure Team at Indesit consulted with outsourcing partner IBM to establish how best to implement Advanced Compression. It was important to Indesit that the cost and efficiency benefits of Advanced Compression should not be limited to the ERP system ECC but also extend to the BI/BW and CRM systems to maximize the savings. The SAP applications are used at virtually all Indesit sites, in Russia, the UK, Turkey, Poland, Germany, Italy, and elsewhere in Europe. The SAP environment is used as the central system, while the IT infrastructure and all applications are outsourced. The applications are accessed by a total of 2,800 users, and together with Oracle Database, they keep Indesit’s essential business processes up and running. “A system failure, however brief, would have serious consequences for business,” says Laura Benedetti. Indesit: focus on Table Compression feature The implementation and deployment of Oracle Advanced Compression was defined by Indesit’s IT team in a detailed project plan, which was worked out step by step. Their target was to achieve average space savings of around 50%. Oracle Database 11g Advanced Compression offers businesses a range of compression features that translate into real cost savings. Advanced Compression includes Table Compression, RMAN Compression, Data Pump Compression and Data Guard Network Compression. The Index Compression feature was first introduced with 10g. Indesit wanted to achieve savings with the Oracle Advanced Compression feature Table Compression (OLTP). Table Compression allows data to be compressed during all types of data manipulation operations, including conven tional DML such as INSERT and UPDATE. In addition, OLTP Table Compression reduces the associated compression overhead of write operations making it suitable for transactional or OLTP environments as well. OLTP Table Compression, therefore, extends the benefits of compression to all application workloads. The benefits of OLTP Table Compression go beyond just on-disk storage savings. One sig nificant advantage is Oracle’s ability to read compressed blocks directly without having to first uncompress the block. Therefore, there is no measurable performance degradation for accessing compressed data. In fact, in many cases performance may improve due to the reduction in I/O since Oracle will have to access fewer blocks. Further, the buffer cache will become more efficient by storing more data without having to add memory. 79 80 Oracle Advanced Compression at Indesit Tests confirm high expectations Before Advanced Compression went live, the IT team and an external consulting company carried out a database analysis. “We were par ticularly interested in the tablespaces. The data reorganization and the activation of Oracle Advanced Compression/OLTP Table Compression were implemented one after the other or in some cases in parallel. Our out sourcer IBM was very much involved throug hout the process,” says Benedetti. Implementation and testing took place on the SAP test and development system, and the ECC system was selected as the first to benefit from Advanced Compression. The results con firmed the high expectations – that Oracle Advanced Compression could reduce storage space by at least 50%. The same procedure was repeated in the quality assurance system so that Advanced Compression could be utilized in the productive system. After the ERP ECC system, Indesit tackled the BI/BW system and then the CRM system – again with substantial space savings of around 50% or slightly more. Huge benefit, minimal effort “Thanks to Oracle Advanced Compression we achieved huge space savings with minimal effort, which resulted in substantial and meas urable cost savings. We are very satisfied with the results,” says Laura Benedetti. The company’s satisfaction is partly due to the fact that the outsourcing fees it pays for SAP system operation are based on resource usage, for example CPU or storage utilization. The intensive application use and growing volume of data meant that resource usage was close to exceeding the agreed levels. Oracle Advanced Compression eliminated this excessive use of resources, reducing utilization to below the agreed fixed-rate level. In concrete terms, Indesit achieved the follo wing database storage / space savings in the three SAP applications: Through Oracle Advanced Compression the ERP ECC data base volume (the required storage resources) was reduced from 8 TB to approximately 4 TB. In the BI/BW system, the database volume was reduced from 5 TB to around 2.5 TB, and in the CRM system from 1 TB to around 500 MB.

Its brands are found in 97 percent of America’s households. Consumers can buy them in grocery, convenience, mass merchandise and club stores. The company sells nearly 13 million packages of food products every day, including 4 million frozen food packages. ConAgra is a Fortune 500 company with net sales totaling 13+ billion US dollars in 2012 and employs more than 26,000 people. For any company trying to foresee the future can be a challenging process. Especially when it comes to accurately determining the size of a database or storage capacities over a period of two or three years. It becomes more than a trivial matter and in some cases it is simply impossible. For everytime that you make a change to the system it must be throughly tested and validated from an infrastructure perspective, an application prespective, as well as from a value prespective. At ConAgra Foods, SAP ECC is the core system used for our manufacturing business, the entire process revolves around it. So anytime we decide to make a change to our environment, we run it up through the landscape before promoting it into production. This gives us a chance to see how it affects the database, hosts, disks, and response times, as well as from the frontend applications. Alarming data / storage growth At the start of 2012, ConAgra Foods realized that it was growing faster than what was initi ally forcasted for a 3 year period in their SAP ERP ECC environment. “Our ECC database was growing at an alarming rate, exceeding projected growth rate estimates and jumping 3 TB in a 9-10 month period. Our current storage environment was capped at 10 TB of SSD with 9.6 TB in use by DB,” says Rene Vana, Lead Database Administrator at ConAgra Foods. Oracle Advanced Compression at ConAgra Foods How could they overcome this challenging trend of increasing data with a limited amount of resources? One solution of course would be to order an additional 10TB of new SSDs, and let the database continue to grow. But this approach wasn’t even considered, as Vana ex plains, “there was no plan in the current budget to buy any additional disk until the next fiscal year.” Starting with a workable action plan Given the situation, ConAgra sought and found an alternative, implement Oracle’s 11g Advan ced Compression for SAP. Oracle Advanced Compression is a beneficial and innovative way of overcoming data growth challenges while meeting the demand for more space. For ex ample, it allows IT managers to effectively handle or manage larger volumes of data with limited IT budgets. ConAgra Foods has long been a customer of Oracle, using the Oracle database as a safe, stable and highly effective pillar of its infra structure, both for its SAP and non-SAP en vironments. Over the last 3 years, the total number of users in the ECC system has grown to over 3000, increasing the load and demand for quicker response times. In a period of roughly 4 months, between September 2011 and January 2012, the database grew by more than 1.4 TB. This above average increase in database growth was due to an unexpected change in business direction that could not have been foreseen by the IT department. More specifically, the business and marketing goals required more data to be kept online and accessible in real time. As ConAgra Foods DBA Manager Jenny Powers explains, “we had to take rapid and effective action to be on the safe side. We were running the risk of exceeding our storage capa city limit for ECC use of 10 TB.” Alternative ways of solving the problem were then quickly investigated and discussed. A direction and a plan needed to be devised to bring the data base growth problem under control. The focal point of the plan should be to significantly decreased volume of data, while reducing the current database foot print, and spending a minimal amount of capital in the process. This can be accomplished by implementing Oracle Advanced Compression. First, ConAgra Foods decided to request an additional 5 TB of SSD, swaping out the old 10TB of SSD for 15TB of new SSD, to relieve growth limitation in the short term, and to provide space to reorganize and compress data. Secondly, start a pilot test to see how much they could actually benefit from implementing compression on an older 6TB copy of the SAP ECC database. This would help set expecta tions, and develop the processes and procedures to solve the problem within the newly added additional 5 TB of disk. Thirdly, by implemen ting Advanced Compression, ConAgra could further reduce the need to buy any additional disk and extend the life the disk they already had in place. Pilot Test Results Total Database Size before and after compression For the pilot test, we used BRSPACE (version 7.2), tables and indexes were compressed in accordance to SAP Notes (#1431296, #1464156, #646681, #541538, #46272, #771191). In addition, we broke out largest table space (9 TB) into smaller sets of Data and Index tablespaces (Data Classes w/in SAP), taking into account the table names, roles and functionality. This would make it easier to re organize the next time around, reducing the need for such large chunks of free space. All the lower landscapes were reorg’d and compressed 85 86 first before moving into production, giving us the opportunity to evaluate the impact on the application and environment. Some of the key things we watched for included dead locks, DB latch contention increases, Disk IO and CPU load. Tests confirmed high expectations We went into our OAC pilot test with two main objectives, reduce the current database size by at least 40%, and find a way to reduce the rapid database growth rates. Both of these objectives were achieved and exceeded based on our initial estimates. “The ECC database size and disk space usage was reduced by more than 60 percent. Our initial expectations were exceeded, we were very impressed,” reported both DBA Lead, Vana, and DBA Manager, Powers. Based on their findings and results, Oracle Advanced Compression was then im plemented in the SAP ECC environment, all the way up through production. SQL Performance Metrics Sample Query used to Validate IO affects of Advanced Compression: SELECT * FROM SAPR3.ZSD_ORDER WHERE MANDT=100 AND ZZCSR between '0000060019' and '0000060030' AND VKORG=1000 AND VTWEG=10 AND VBTYP='C' AND ZZERDAT_O > 20110720; Disk reads, buffer gets, time waited, I/O wait time all showed decreases. Table and Indexes before and after Compression used in query. Oracle Advanced Compression at ConAgra Foods Other DB Performance Metrics observed From a SAP Metric perspective we saw the “%DB Time” wait go from 56%, down to around 38%. We attributed this change to a combination of the new storage array consist ing of the 15TB of SSD and compression. Where the disk change out got us a 10% boost and the Oracle compression an additional 8-10% of the “%DB Time.” Our “Average Response Time per Dialog Step” dropped from 500ms to 435ms after just im plementing compression. Our backup times went from 5.62hrs for a full backup using rman across 8 channels down to around 2hrs after releasing the free space (green bar dropping in chart below) back to the OS. After implementing Advanced Compression in Production By having the DBA team ReOrg in chunks of 300GB to 1000GB of data every weekend, and starting in July. We were able to complete the project by DST weekend, only taking off a couple weekends to attend Oracle Open World. The DBA team was able to reclaim over 5TB of disk space previously held by the database, and watch the Database drop from 9.6TB in size, down to 4.2TB, leaving us with about 10TB of free disk space for future growth over the coming years.

Oracle RAC 11g fully met our expectations by delivering a high-availability, high-performance and flexible SAP database within our template approach. Our overall experience with Oracle RAC and ASM was very positive.” – ARNE ZIEGLER, Infrastructure Group Leader for Architecture at LUNAR GmbH High-profile retailer opts for Oracle RAC (Real Application Clusters) in one of the biggest projects in the European retail industry O R A C L E R A C 1 1 G AT E D E K A : DELIVERING SECURITY AND STABILITY With 12,000 stores, almost 300,000 employees and an anticipated turnover of € 42.1 billion, the Hamburg-based EDEKA Group is a leader in the German food retail industry. Every day, 12 million customers buy items of the group’s food and non-food ranges with up to 50,000 articles. EDEKA’s IT subsidiary, LUNAR GmbH, is responsible for dovetailing retail, wholesale and central business processes. The company pro vides the full range of innovative IT services. As well as being the name of the company, LUNAR is also the name of a program to develop and roll out a requirements-based standard software solution for EDEKA in a partnership between the seven regional com panies, headquarters and partner SAP. All three levels of the enterprise – retail, regional and headquarters – use one standard, integra ted SAP-based software solution. The project, one of the most ambitious in the European food retail industry, involves the Oracle RAC 11g database for SAP with Automatic Storage Management (ASM). The infrastructure tech nology solution serves as an anchor providing security and stability to satisfy the group’s key availability and performance requirements. 7040 instances of Oracle RAC 11g are being used in the project with x86 server technology and SuSE Linux. The LUNAR solutions will be rolled out across the EDEKA regions in various phases. The complete infrastructure solution for all EDEKA units currently addresses some 450 TB of net SAN storage. EDEKA / LUNAR GmbH Industry: Retail dd Workforce: appr. 300,000 Oracle products and Services: Oracle Database RAC 11g, with ASM Oracle Recovery Manager (RMAN) Oracle ACS Standardized technology stack The high-profile retailer has already made significant progress in its IT reorganization. The different regions have always operated their own data centers with their own system environments. Local and regional system rollouts of the LUNAR x86 infrastructure pro duct took place in all seven EDEKA regions and at headquarters in Hamburg, and in most places the changeover to the newest release is already underway. The individual implemen tations are projects in their own right, integra ting the new systems into the existing system technology. Arne Ziegler, Infrastructure Architecture Group Leader at LUNAR GmbH, says: “LUNAR has already converted a large part of its own SAP system landscape to the new infrastructure solution, as has one large EDEKA region. This represents some 300 SAP systems, including around 119 systems in Oracle RAC.” Key benefits: high availability, cost reduction, high performance, less complexity, high scalability; future-oriented infrastructure with innovative technologies, based on standards SAP: Retail, ERP ECC 6.0, Netweaver BW, Portal and others Other Infrastructure: IBM Bladeserver, SuSE Linux, EMC Storage, Veritas Cluster (for SAP SPOF processes), VMwar 90 “ASM ensures effective administration and highly productive management of the RAC databases,” is the opinion at LUNAR.” – Arne Ziegler, Infrastructure Group Leader for Architecture at LUNAR GmbH Any business software roll-out in the LUNAR program is based on a standard infrastructure platform. This platform is based on the EDEKA Group’s approved design rules and is configured on the basis of an x86 computer architecture in the LUNAR lab to create a fine-tuned technology stack that serves as a system template for productive data center use. Crucially, the LUNAR x86 infrastructure plat form delivers a scalable, cost-effective and highavailability SAP IT infrastructure system with standardized standard components and support processes that also represents a secure invest ment. The application software template is then adapted to this system. The LUNAR x86 infrastructure platform, a standardized but flexible complete solution, consists of an application platform (to support the SAP application stack), Oracle database, OS/virtualization, x86 server hardware, and storage. The package also includes a design concept, automatic installation routines for the OS environment, configuration parameters, installation guidelines, and lists of test cases to check that the implementation is fully fun ctional in the EDEKA data centers. LUNAR handles solution support and ongoing product development on behalf of the EDEKA Group. One key design rule is that there are few or no dependencies between individual function blocks and the system is largely manufacturerneutral at all levels. In terms of software the new standardized SAP system landscape will replace several individual solutions and various retail pro grams, and in terms of infrastructure, host systems and varus UNIX systems. The overri ding objective throughout is to reduce invest ment and operating costs (including support and maintenance) through standardization. Oracle – the sound choice on business and technology grounds Before implementation is carried out, the LUNAR lab performs compatibility tests to see which vendor products can be used for each function block in the infrastructure solution. “As far as the SAP database is concerned, the most important evaluation criteria were avai lability, stability, performance, and future compatibility,” says Ziegler. “The future data base had to support both smaller and larger system versions as required. Both technological and operational factors made Oracle and Oracle RAC the obvious choice.” He adds: “We had already had positive experience with Oracle database technology as a high-availability so lution and more generally with Oracle data bases in SAP and non-SAP environments, which also tipped the balance in favor of Oracle.” Oracle Database 10g (single-instance) and Oracle RAC 10g were already in use through out the EDEKA Group. Oracle Database 11g and Oracle RAC 11g for SAP provide even more customer benefit with useful extra fea tures such as disk space reduction (Advanced Compression) with lower hardware costs, hig her performance, improved manageability, and above-average high availability (with disaster recovery) for SAP applications. Satisfied expectations “Oracle RAC is a vital infrastructure compo nent that helps us to achieve 99.9 % overall IT availability and satisfy our design and architecture criteria. Oracle RAC 11g fully met our expectations by delivering a highperformance, high-availability, efficient and flexible SAP database within our template approach. Our overall experience was very positive,” says Ziegler, who is extremely satis fied with Oracle RAC 11g so far. Oracle RAC and ASM at EDEKA Lunar EDEKA runs the Oracle RAC productive data bases, based on an active/active architecture, on physical servers, each of which is part of a two-node cluster environment. If one node becomes unavailable for any reason, the other immediately takes over the workload of the failed node in the local data center. In addition to RAC databases, EDEKA uses Oracle Data base 11g single-instance databases, for example in development systems and smaller productive systems with lower SAPS requirements. The failure of a cluster node has been tested several times by simulating a range of failure scenarios in the lab. As well as a local data center there is a second data center with the same hardware for disaster recovery. In the event of a disaster it can provide 100 % fai lure capacity with no need to switch back to the original data center once the problem has been resolved. Effective administration with Oracle ASM The Oracle RAC databases are managed and operated with Oracle Automatic Storage Mana gement (ASM). “ASM ensures effective admini stration and highly productive management of the RAC databases,” is the opinion at LUNAR. The company is also evaluating the possibility of using ASM for mirroring purposes, which is very straightforward. Synchronous data repli cation is currently taking place at storage level. All in all, Oracle RAC 11g with ASM is en abling EDEKA/LUNAR to operate a scalable, cost-efficient and high-availability SAP IT infrastructure system representing a secure investment with standardized standard com ponents and support processes – which ulti mately translates into hard financial benefits. The solution also offers maximum future compatibility. EDEKA/LUNAR may well choose to expand its use of Oracle features. For example, the group is evaluating the option of protecting itself against logical errors in the database function block with the standby database so lution Oracle Data Guard. The group is also considering the possibility of harnessing ad ditional benefits of Oracle RAC: perhaps by using the innovative database clustering tech nology not just to deliver high availability, but also for scaling purposes, or by using Oracle Database 11g Advanced Compression. 91 92 O r a c l e A C S – Tr i p l e O a t A k z o N o b e l “Oracle ensured a risk-free migration with zero downtime, which resulted in better performance and cost savings.

With operations in more than 80 countries, AkzoNobel is a Global Fortune 500 company. Its products protect buildings and infra structures around the globe and promote safety and good health, while bringing color to the world and furnishing homes and offices. In addition to paints and coatings, AkzoNobel’s chemicals serve as essential ingredients in everything, from ice cream to asphalt, soup to soap, and plastics to paper. $1 to $5 Billion Oracle Product and Services: • Oracle Database 11g • Oracle GoldenGate AkzoNobel wanted to upgrade its entire Oracle Database 10g infrastructure to Oracle Database 11g with zero downtime to ensure business continuity. In addition, the company wanted to reduce its total cost of database ownership and ensure an easier roll-out for the entire production system in new countries. Following the upgrade, AkzoNobel reduced its total cost of database ownership approximately 50% by compressing storage from 3.7 to 1.8 terabytes. In addition, it enhanced productivity for several tasks, such as monthly reporting and customer service, by as much as 100%. Challenges • Upgrade the database system containing all production data used in business intelligence, supply chain management, and enterprise core component systems, with zero downtime to ensure full, business continuity • Ensure an easier roll-out for the entire production system in new countries by using copies of the production database for testing purposes • Lower total cost of ownership by reducing costs of back-up, storage, and database maintenance • Improve overall productivity for customer service and monthly reporting systems by enhancing database performance, allowing for faster order entries and searches for information to answer customers’ questions Solutions • Ensured full business continuity with zero downtime, while upgrading to Oracle Database 11g using Oracle GoldenGate • Enhanced production system deployment in 15 new countries by using database copies for realistic testing without interfering with the live production database • Reduced total cost of ownership approximately 50% by compressing storage from 3.7 to 1.8 terabytes and lowering database backup costs • Improved productivity for several tasks by 50% to 100%, such as for mobile order picking, by allowing customer orders to be automatically picked from the shelves; monthly financial and productivity reporting; and customer service, due to the ability to enter orders and answer customer queries more quickly • Reduced time to dialog with the database from approximately 800 milliseconds to 450 millise conds for more than 8,500 users, even during peak usage periods, when there are 1,400 con current users Implementation Process Preparations in the first phase took approximately six months. It then took AkzoNobel approximately two months to complete the actual migration and compression for all 21 systems.

As a strategic database platform, Oracle is an essential element that supports our realignment.” –MAX BÜTTIKER,MANAGER SAP customer Competence Center, Helsana-Group Switzerland’s biggest health insurer replaces mainframe in SAP environment with new strategic www.helsana.ch Industry: Insurance HELSANA GROUP REPLACES DB2 W I T H O R A C L E D ATA B A S E Workforce: 3,000 Oracle products: Oracle 11.2.02 for SAP Key benefits: Strategic database, cost savings, more flexibility and better performance SAP: ERP ECC 6.0, FI, CO, HCM, HR-PF, FS-ICM Enterprise Portal, ESS, MSS, LSO, ECM Infrastructure: Database layer IBM servers with Red Hat Linux, application layer Standard Intel servers with Windows and VMware ESX Last year the Helsana Group decided to phase out its z/OS mainframe environment in favor of a new client/server IT landscape. It was decided to replace IBM’s DB2 with Oracle Database as the group’s strategic database platform. “In March 2012 we passed an important mile stone on the road to a new IT landscape,” says Max Büttiker, Manager of the SAP Customer Competence Center at Helsana. On this date, the databases for the SAP applications, which have been in use for a long time and have around 3,000 users, were migrated from the IBM zOS mainframe with DB2 to a client/ server hardware setup (with x3850 as the data base server) using Red Hat Linux and Oracle Database 11g. The application servers are standard Intel systems running Windows and VMware ESX. Support for migration project The SAP applications themselves were virtu ally unaffected by the project to migrate from DB2 to Oracle Database 11g. Infrastructure experts from SAP Switzerland and Oracle collaborated on the project. The migration con cept was designed by SAP, who also supplied the migration tools for the export of the DB2 (Version 9.1) database. One of the first steps was to create a sandbox environment and test the export tools. The various systems, including the D, Q, and P systems, were then migrated and the latest version of Solution Manager was installed and thoroughly tested. “At the end of the day, we implemented the DB2-to-Oracle migration exactly as planned,” recalls Büttiker. “A few issues with the export tools were resolved with the help of SAP. The migration required a Uni-code conversion, which was also successfully implemented. The adaptation of various interfaces also went smoothly, with no major delays.” Helsana DB2 migration to Oracle Database “New environment running perfectly” The new SAP environment with Oracle Database 11g is “running perfectly”, says Büttiker with satisfaction. Even without detai led measurements, it was clear from the outset “that response times have im-proved, even though no database optimizations have been carried out so far”. As the IT team at Helsana also discovered: “The high integration of Oracle in SAP has several advantages, for example in system administration.” So far the Helsana Group has not taken advan tage of Oracle Database 11g features such as Advanced Compression or Advanced Security. However, these are possible options for the future, especially as the company is already familiar with compression processes in a data base environment. The Oracle database for the ERP system is currently around 500 GB. “Replacing the mainframe has allowed us to reduce IT operating costs in the SAP environ ment and increase the flexibility of our IT use,” says Büttiker. “As a strategic database platform, Oracle is an essential element that supports us.” Helsana Group The Helsana Group is Switzerland’s leading healthcare insurer, providing illness and accident insurance and other health-related services to private individuals and enterpri ses. With premium revenues of 5.6 billion Swiss francs, the company occupies the top position on the Swiss insurance market. The Helsana Group operates in all regions of the country and employs 3,000 people. It is a non-listed stock corporation structured as a holding company. The Helsana Group in cludes Helsana, Progrès, Sansan, Avanex and Maxi.ch (for more information, visit www.helsana.ch). The Helsana Group protects almost 1.9 million people in Switzerland against the financial consequences of illness, accident, maternity and old age. In its corpo rate insurance business, which operates solely under the Helsana brand, Helsana insures 58,000 companies and organizations (with over 710,000 insured persons) against the financial consequences of employee incapacity due to illness or accident. The group also offers corporate health management services. 95 96 ORACLE ADVANCED CUSTOMER SERVICES FOR SAP Database Services for SAP Environments Oracle Support for SAP A key attribute to the deep customer focused partnership with SAP, is SAP’s requirement for a permanent onsite technical staff.

In order to minimize the risk of unplanned downtime in a mission critical environment, IT organizations must pro actively plan for failover and recoverability. Oracle database products enable different approaches, such as hardware clusters, mirror technologies, standby databases, RAC and Data Guard. Oracle Advanced Customer Services can advise on the comparative advantages and disadvantages of these different approaches as it applies to your particular situation and, of course, assist with the implementation of the chosen solution. The majority of all SAP ERP installations run on an Oracle database. The Oracle Advanced Customer Services for SAP group is certified by SAP for database migrations and can assist companies who wish to migrate their SAP Business Suite installation from a non-Oracle database to Oracle. A much valued aspect of Oracle’s migration services is the deep fami liarity of the change from a DBA perspective. Oracle Advanced Customer Services can assist your staff in executing a migration plan while familiarizing them with the new database operations. Oracle RAC Enablement for SAP The “Real Application Clusters” (RAC) option enables the distribution of your database instance across different servers, or nodes. This offers new possibilities in the area of high avai lability of an Oracle database system, and also provides greater flexibility in the dimensio ning and scalability of system resources. Oracle Advanced Customer Services provides professional services, in the areas of planning, technical workshops and implementation, to assist you with enabling RAC for your SAP environments. Oracle Partitioning for SAP Customers Oracle Partitioning is an option to Oracle Database 10g Enterprise Edition (also along with Oracle Database 11g certification). At a technical level, Oracle Partitioning allows tables and indexes within a database to be subdivided into smaller pieces. Oracle can “partition” a table by ranges of values, so for example, the data for Jan 1, 2010 through Jan 31, 2010 can reside in its own partition. Oracle can also partition a table by a list of values, so, for example, North American data is in one partition, while the European data is in another partition. Partitioning is a critical feature for managing large databases. Partitioning is the feature that allows a database to scale for very large datasets while maintaining consistent performance, without an unduly in-creased need for hardware resources or administrative efforts. Oracle Partitioning is embedded into the core database engine and supported by Oracle’s administrative tools. From a SAP application perspective, partitio ning is completely transparent. Thus, no chan ges need to be made to the application or to the SQL statements in order to use partitioning. Partitioning for SAP has been supported since SAP Release 4.6C (see SAP Note 742243) for the SAP Kernel 6.20. Oracle Advanced Customer Services (ACS) for SAP Oracle Database 11g With the many new capabilities and enhance ments of Oracle Database 11g, such as Advan ced Compression, DirectNFS, Secure-files and Online Patching, enthusiasm and advanced demand continues to build for fast deployment.

Oracle Advanced Customer Services ACS at Centrica 101 ORACLE ADVANCED CUSTOMER SERVICES AT C E N T R I C A , U K Centrica (British Gas) serves around 12 mil lion homes – half the homes in Britain and nearly 1 million businesses. High availability is a main focus. Multiple large SAP applica tions were at the time running on a huge Oracle database with more than 23TB of data, on HP UX systems. Centrica planned a move of their four most important SAP platforms to a new data cen tre. Due to interdependencies between these mission critical systems, they all needed to be moved in one go. Along with the transition, the Oracle database was to be upgraded to 11iR2. Long outages during the change were out of the question. ACS had been in the account for many years and got engaged to assist with the migration, because Centrica trusted their expertise. A team of SAP specialists from the ACS SAP Expertise Centre in Walldorf, Germany set to work and planned and delivered the transition. Using the ACS O2O (Oracle-to-Oracle) methodology, Centrica were able to achieve migration of 2TB an hour, completing the migration well within the given 24 hours downtime window. The ACS team provided guidance and best practice and was able to identify and mitigate any risk factors along the way. After the August bank holiday weekend of the transition, the systems went live, providing a stable service to the users from the first hour. ACS experts stayed onsite during this initial phase to provide immediate support and gui dance and were able to quickly resolve the few minor post migration issues experienced.

It allowed us to start preparing for this important migra tion, only a few months after initial contact with Oracle. And indeed, we achieved our goals in a very short timeframe with minimal downtime for the SAP system, while reducing the size of our target database by 50%.” – MARION FOKKINGA, NXP Semiconductors N.V.

Founded in 2006 and formerly a division of Philips, the company provides highperformance, mixed-signal, and standard product solutions that use its leading expertise in radio frequency, analog, power management, interface, security, and digital processing. These innovations are used in a wide range of automotive, identifi cation, wireless infrastructure, lighting, industrial, mobile, consumer, and computing applications. NXP invests more than US$550 million per year in research and development and has approximately 11,000 issued and pending patents. NXP operated SAP enterprise resource planning (ERP) and Oracle Database, Enterprise Edition 10g. The company had scheduled a data center migration with change of hardware and operating system, and upgrades for the database and SAP ERP. Nevertheless, using traditional approaches with native SAP tools (r3load), it would have taken approximately 20 hours to migrate 7.5-tera bytes (TB) of SAP application data stored in Oracle Databases. As a 24/7 manufacturer of elec tronic products used in automotive, lighting, aero space, computing, and many other applications and industries—such as chips, sensors, and diodes—NXP needed to keep the SAP systems up-and-running, with only minimal downtime during migration because business processes would otherwise have been interrupted. Upgrading to Oracle Database, Enterprise Edition 11g based on proven Oracle methods and using O2O (Oracle-to-Oracle) Transition Services, NXP estimated that it completed the migration twice as fast as it would have using native SAP tools. It also reduced the required storage space for the company’s SAP application data by approximately 50%, while shortening total database downtime from hours to minutes. Challenges • Migrate a complete data center with change of hardware and operating system, upgrades of the database, and SAP ERP within less than eight hours downtime to avoid interrupting business processes, like shipments of the company’s 24/7 production, which includes tens of thousands of electronic products used in automotive, lighting, aerospace, computing, and many other industries • Migrate 7.5-TB of SAP application data to Oracle Database 11g within the scheduled down-time of a few hours—impossible to realize using native SAP tools (r3load), which would have required approximately 12 hours for the migration • Reduce storage costs associated with SAP application data and free IT resources required to maintain it O r a c l e O 2 O – N X P S e m i c o n d u c t o r s N .

This was due, in part, to the short-term schedule, but also to the excellent relations between NXP and Oracle, and the fact that O2O Transition Services are available for all operating systems and are fully hardware-independ ent–a key benefit for this project,” said Marion Fokkinga. “Since we run SAP Resources – Marion Fokkinga, Additional High Technology successes with Oracle Database enterprise resource planning on Oracle Database” Teamlead Technology Advancement SAP, NXP Semiconductors N.V 104 SUPPORT FOR ORACLE “RESOURCE MANAGER” OPENS NEW HORIZONS OF PRODUCTIVITY FOR SAP USERS All4it Group • For additional information regarding All4it, please visit our website at www.All4it.com or contact Olivier Lambert at +33 6 08 73 09 92 “Resource Manager” is the native scheduler of Oracle server resources. It helps balance the resources between different applications and different servers (in the RAC case). With a simple implementation, it allows you to create rules in case of use of several SAP instances on the same physical server. This way, you can also use Resource Manager to explicitly allocate CPU resources to the multiple work loads or applications that are sharing the database. For example, you can prioritize a « qualification » landscape against a « develop ment » one. So you can configure CPU allo cations and limits for each application in a consolidated database, and therefore auto matically manage case of overflow of one over the other. It allows also you to define safeguard in case of malfunction of a component, or a trans action ...Using Oracle Database Resource Manager, you can ensure that your database’s CPU load is always healthy, thus avoiding all of these problems. A detailed white paper on the implementation and support with SAP is available at the following address: http://www.oracle.com/technetwork/database/ focus-areas/performance/resource-manager twp-133705.pdf “Customer case 1”: Managing multiple instances of SAP/R3 databases on a single server Background The Customer currently uses the physical partitioning technology offered by the IBM pSeries to manage its various test, qualifica tion and production instances. Although Oracle recognizes physical partitio ning by the IBM pSeries, this means that the Customer1 must satisfy the minimum pro cessing requirements of each partition created. Technology alternatives Fortunately, Oracle (and SAP, thanks to certi fication through ALL4IT) provides an alter native to this problem, which is supported by SAP. 1. Oracle single-instance approach Currently, the following process is applied for each SAP environment: • Install Oracle distribution medium (ONE ORACLE_HOME) • Create an instance (e.g. “SID”) • Install on “SAPR3” schema in the “SID” instance However, SAP now supports multiple schemas. In other words, it is possible to have one Oracle installation and a single instance for the QBR, DBR, QBX and QBY schemas. Advantages: • Saves disk space • Saves Oracle licenses Disadvantages: • Bigger database and therefore more cumbersome to use (although TBS exports are possible) • Resources can no longer be distributed among SAP schemas. It is therefore no longer possible to allocate more or less capacity to a particular instance.

Founded in 1874, the company has always been a pioneer in the sector and is continually setting new trends with its comprehensive system solutions. Its product range includes sanitary systems with installation systems, cisterns and mechanisms, faucets and flushing sys tems, waste fittings and traps, shower toilets and piping systems with building drainage systems and supply systems. Geberit is listed on the Swiss stock market, has agencies in 41 different countries and maintains 16 production sites in seven countries. In 2011 the Geberit Group (global workforce in excess of 6,000) produced a turnover of 2.1 billion Swiss francs. The focus of Geberit’s trend-setting change in infrastructure was to optimize cost-effectiveness in the long term. “This involved us putting all components, including the Oracle “SAP database” and the non-Oracle standby database solution used, through their paces. From a cost standpoint, comparing with IBM DB2 didn’t bring any improvements so we decided to continue using the Oracle Database for SAP. And in terms of the standby database solution, Geberit decided to use Oracle Data Guard 11g. We were convinced that combin-ing this with Oracle Database 11g would deliver numerous benefits. And that proved to be the case,” explains Manfred Bantle, Head of SAP Service Center. 2013: 20 years of Oracle for SAP Standby databases: long history, ongoing Geberit has something to celebrate in 2013 as the company will have been using the Oracle Database in conjunction with SAP applications for 20 years. Over this time the IT infrastructure environment and the landscape in which the products of the European market leader in sanitary technology are used have of course changed. improvements As far as the SAP infrastructure is concerned, the global company realigned its strategy in 2011. An initiative known as “SAP infrastructure fit for the future” was implemented. This basically meant Linux rather than UNIX, and x86 blade servers (including virtualization) rather than Itanium UNIX servers. The approach taken over the years to use standby databases to protect data / “SAP databases” (poten tial logical errors, increase in availability) as part of the Geberit disaster recovery / high-availability concept has stood the test of time. The group of companies has two transnational data center sites, located over 100 kilometers apart; one is at the Group headquarters near Rapperswil in Switzerland and one is in Pfullendorf in Germany, which is also home to the successful sanitary specialist’s central European warehouse. The SAP servers (in total 14 productive systems for applications, around 3,000 SAP users) responsible for all sites around the globe are split between the two sites. Geberit Group – Oracle Data Guard 11g A backup data center is operated at each data cen ter site. The respective data center and backup data center mirror the data (databases) and pro duce or generate the standby databases. A power line (100 Mbit/s) links the two data centers (in Germany and Switzerland). There is a reserved power line (50 Mbit/s) for the standby databases. The company had been using its standby data-base solution for a long time and had many reasons for replacing it with Oracle Data Guard 11g. As Bantle, head of the SAP Service Center reports, “Oracle Data Guard allowed us to save money and make progress with our consolidation plans. It also enabled us to significantly develop what we had accomplished in terms of standby databases – something we had wanted to do for a long time. The decision to use Oracle Database11g was also linked to the choice of Oracle Data Guard 11g.” Rapid implementation using template approach Oracle Data Guard 11g was implemented by the Geberit IT team as a physical standby database (without automatic fail-over function) in line with the SAP requirements and together with the Data Guard management software, Data Guard Broker. The Flashback Database option was also installed. This enables a standby database to be very quickly reset to a chosen point in time, to be used as a read/ write system and to be changed back to the pre vious current time. It can then be immediately put back into recovery mode. The various standby databases (Oracle Data Guard systems) were im plemented at the same time as Oracle Database 11g during the x86 Linux SAP migration (SuSE Linux rather than HP-UX; HP blade servers rather than Itanium servers; VMware used for virtualization). Geberit’s IT specialists learned how to implement and operate Data Guard in a two-day workshop run by a Data Guard expert from Oracle. SAP Basis Administrator Daniel Rothmund comments, “we built a test system with Oracle Data Guard. To quickly familiarize ourselves with and use the solution, we used templates provided by Oracle. Later on, we used these templates to produce our own generator with automatic script generation for quickly and easily setting up and configuring a standby database.” Wealth of usage scenarios delivers meaningful benefit The well-known sanitary specialist is benefiting in numerous ways from using Data Guard 11g with Flashback – in addition to the advantages gained from using Oracle Database 11g (such as storage requirements being roughly halved thanks to Oracle Advanced Compression). “Demonstrable added value and a major additional benefit can be gained from the huge number of different and flexible ways in which Oracle Data Guard and the Flashback Database option can be used and the fact that the package offers much more than just availability or disaster recovery. This results in great cost effec tiveness,” explains Bantle, head of the Geberit SAP Service Center. “Oracle Data Guard allowed us to save money and make progress with our consolidation plans.” – Manfred Bantle, Another benefit of the Oracle Data Guard/Oracle Advanced Compression combination is related to the network traffic. With Oracle Data Gguard Network Compression (a feature included in the Oracle Advanced Compression bundle), redo data may be transmitted in a compressed format to reduce network band-width consumption. For the data transfer between production and standby database via WAN, Geberit measured a compression rate of 3, i.e. the data to be sent over the network was compressed to one third of its original size. Geberit also uses the sophisticated Oracle standby database solution to realize performance-critical evaluations, to test batch inputs, batch jobs, release upgrades and to activate enhancements for example. Data Guard has also be used during a live switch over when relocating an entire system (Oracle Database including SAP BW with a total size of around 5 TB) from Rapperswil to Pfullendorf. While this certainly wasn’t an everyday task, it was completed smoothly. But that’s not all... As part of the “SAP infrastruc ture fit for the future” initiative, Geberit has deci ded to discontinue the two local backup data centers in Rapperswil and Pfullendorf in the long term. The two data centers will then also assume backup duties. Oracle Data Guard 11g including the Flashback Database will also have an important role to play in this consolidation process.
