Oracle Deployment Flexibility Same code, functionality & tools across operating systems - Enterprise Manager Grid Control - SAP BR*Tools - SAP DBA Cockpit Customers can choose most cost effective platform Customers not locked into any particular platform Oracle to Oracle migration tools for changing OS platform: - Fast and efficient - O2O (Oracle to Oracle Offline migration) - Triple O (Oracle to Oracle Online Migration) - Transportable Tablespaces
Oracle Database 11g R2 Real Application Testing Real Application Testing Option Unique to Oracle Able to capture and replay full production database workload Important for 10.2 to 11.2 Upgrade tests, Important for testing new features More functionality, more flexibility, less expensive than 3rd party products
Real Application Testing with Database Replay Recreate actual production database workload in test environment Capture workload in production including critical concurrency Replay workload in test with actual production timings Analyze & fix issues before moving to production Client Client Client Production Test Middle Tier Replay DB Workload Oracle DB Capture DB Workload Test migration to RAC Storage
Real Application Testing SQL Performance Analyzer (SPA) Test impact of change on SQL query performance Capture SQL workload in production including statistics & bind variables Re-execute SQL queries in test environment Tune regressed SQL and seed SQL plans for production Client Client Client Production Test Middle Tier Re-execute SQL Queries Oracle DB Capture SQL Use SQL Tuning Advisor to tune regression Storage
Snapshot Standby Test with Production Data Before Deployment Physical Standby Apply Logs Open Database Back out Changes Snapshot Standby Perform Testing Continuous Redo Shipping Use Standby Database for testing and development - Eliminates cost of DR - Justify full scale test and DR environments by combining into one Preserves zero data loss while in test/dev mode - But no real time query or fast failover Similar to storage snapshots, but: - Provides DR at the same time - Single copy of storage

Oracle Database 11g R2 Online Patching Patches are applied while the database is up and running: Works for both Single Instance and RAC No more planned downtime needed for patching Processes jump to patched code at a safe execution point. Online patches are activated at an instance level - Different than traditional patches activated at the $ORACLE_HOME level Applying an online patch is performed using OPatch and MOPatch - also possible to apply via EM deployment procedures Each patch is assessed to determine if it can be applied online - The ultimate goal is to make all patches online patches

Most Efficient Use of Disk Space Variable length number representation Variable length character representation Variable length Unicode representation Highly compressed bitmap index technology
Storage Efficiency: Technology Stack Advanced Compression (Oracle 11g) Partitioning + Compression (Oracle 10g) Index Key Compression (Oracle 10g) Data Compression (Oracle 10g) Efficient Data Storage Most efficient storage of data - Number values - Bitmap Index Most comprehensive set of compression options Advantages increase when used in Combination with other Database options like Partitioning Easy administration - Reduces the number of required reorganizations
Oracle Database 11g R2 Advanced Compression OLTP Table Compression RMAN Backup Compression Unique to Oracle Expdp Compression Data Guard Network Compression Unique to Oracle SecureFile Compression for in-line & out-of-line LOB data Unique to Oracle for out-of-line LOBs - IBM can only do in-line compression Out-of-line LOBs are more used than in-line LOB data in SAP products such as; - SAP CRM - SAP XI - SAP Portal - SAP R/3 (almost all non-cluster tables use out-of-line LOBs)
<Insert Picture Here> Manfred Fischer, Manager of SAP system Maintenance, SWM Services GmbH, Information and Process Technology Testing results of Oracle Advanced Compression for SAP: When we were recording the basic data over two days for the test, we couldn t find any negative effects on the CPU or I/O load of the production system and the dialog response times didn t change. The compression result was quite impressive. The amount of disk space shrunk from almost 3.6 TB to around 1.6 TB, resulting in a space saving of 55%. Oracle Database for SAP Technology Update #19
Performance Improvement Factor Oracle Database 11g R2 SecureFiles SecureFiles 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) SAP VBDATA Throughput (Insert/Read/Delete) 2,5 2 1,5 1 0,5 0 1 2 4 8 16 32 64 row size in KB LONGs (9.2,10.2) LOBs (10.2,11.2) Securefiles 11.2
Flashback Database to reduce downtime Suitable for any DB size A new strategy as alternative to point in time recovery Eliminate the need to restore a whole database backup (reduces downtime) Integrated seamlessly with RMAN & BR*TOOLS (SAP note 1125923) Think of it as a continuous backup Restores just changed blocks It s fast - recover in minutes, not hours It s easy - single command restore RMAN> flashback database TIMESTAMP to_timestamp('2009-03-15 16:00:00', 'YYYY-MM-DD HH24:MI:SS'); SQL> flashback database to restore point <restore point>
Table & Index Partitioning SAP Support SAP NetWeaver BW All types of partitioning are supported Range partitioning used by default Same set of tables can be partitioned in all systems Standard solution (part of installation) SAP OLTP (e.g. ERP, CRM) All types of partitioning are supported Partitioning not used by default candidates need to be selected for every system Oracle Support & Services for SAP can be engaged SAP provides Partitioning Engine: SAP Note 1333328 As of SAP_BASIS Release 700 and with Oracle 11.2, Sub- and Interval Partitioning are also supported (SAP Note 742243)
