Oracle 10g @SAP



This only affects Unix/Linux-platforms! Windows platforms are not affected.

Starting with Oracle patchset 10.2.0.4 Oracle provides socalled Patch SetUpdates (PSU)

A PSU is a collection of important fixes encountered by Oracle customers

Oracle releases a new PSU every three months

The PSUs will contain the Critical Patch Updates (CPU)(Oracle CPU concept will vanish)

PSUs must be applied on top of an already installed Patch Set

New Oracle Patch Concept:Patch Set Updates (PSUs)


Oracle database patches for Unix-platforms are now delivered in form of so-called SAP Bundle Patches (SBP)

– Initial Oracle versions: 10.2.0.4.4 & 11.2.0.1.1

A SBP 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. The next SBP will contain all previous patches and thenew patches in addition.Notation of SBPs:

SAP_<Oracle-version>_<YYYYMM>_<plattform>.zipExample: SAP_102044_201004_AIX.zip

For the installation you'll need MOPatch Version 2.1.1 or higherFor more details please see SAP note 1027012

Oracle 10g @SAP


SAP only certifies Oracle Database 11g Release 2

Only SAP products based on 6.40_EX2 kernel and later get certified with 11.211.2 support only for SAP products which are in SAP Extended Maintenance at least until the end of 2010

SAP 11.2 certification and Rollout happens in three OS waves (due to availability from Oracle)

SAP 11.2 certification happens in three stages:

Stage1: Runtime certificationAllows 11.2 database upgrade of existing SAP systems

Stage 2: SAP Upgrade and Enhancement Package Update certificationAllows SAP Upgrades and Enhancment Package Updates of Oracle 11.2 based SAP systems

Stage 3: Support for Oracle 11.2 based direct SAP installations (incl. Unicode Migration)Allows direct SAP system installations with Oracle 11.2

11g Rollout Schedule

Deferred Segment CreationEmpty database objects will not consume any disk spaceVery important for SAP environments as 60-70% of all tables, lobs, indexes andpartitions in an SAP installation are empty

Saves disk spaceImproves query response times on space objects in Oracle Data DictionaryMakes database install part for SAP a lot faster

- Creation of empty tables, lobs, indexes and partitions are dramatically faster

Performance Impact when using ACO on production database- Measured through Capture Replay Functionality of Real Application Testing Option

- 10.2.0.4 production workload was captured for more than 2 days

- No impact on production database during capture

Results:

- Factor 2.2 Space Savings

- 60% less physical reads

- 5% less physical writes

- 10% better database cache hit rate

- 30% higher redo rate

- No overhead in CPU consumption

Implementation Guidelines for Compression Technologies in SAP Environments1. Start with Index Compression

- Improves R/3 Performance the most as all database access in R/3environments is index based, especially index range scans

- Up to 20% disk space reduction for complete database2. Implement OLTP Table Compression

- No real query performance benefit in R/3 environments- Provides very good disk space savings

3. Implement SecureFiles Compression- Very important for SAP Applications like CRM or XI who store large

(uncompressed) amount of data in LOBs.4. RMAN Backup Compression

- Additional disk space savings (even if database tables and indexes are alreadycompressed)

Partitioning Tools for SAP/Oracle non-BI systems

Motivation

Archiving of historical application data in SAP systems is a big challenge:

Archiving is a continuous process and generates significant system load

Archiving increases index and table fragmentation; reorganization of indexes and/ortables is a time- and resource-critical process

Range partitioning can be used to separate historical and current production data in order tominimize the above impacts

Problem: Application tables usually do not have a direct time dependent column in theprimary key

An alternative is to use an indirect time related column like document number, whichexists in large application tables and is usually part of the primary key

Defining suitable ranges based on document number is difficult

Transformation of an unpartitioned table into a partitioned one can be done online withOracle Table Redefinition package, but this is not a simple admin task

© SAP 2010 Development Update SAP on Oracle, Page 26

Full Integration of Range Partitioning into SAP OLTP products (e.g. ERP)

Partitioning Engine offers a predefined set of around 30 application tables to be partitionedbased on time based criteria

Existing non-partitioned tables will be converted through ABAP/SAP BR*Tools taskPartition Maintenance is fully automated through internal SAP SM37 job (no needfor DBA intervention)

PrerequisitesSAP systems based on 6.20 WebAS release and higher. Examples:

SAP ECC 5.0, ECC 6.0, Business Suite 7Requires minimum ABAP Basis Support Package (SP) level:

6.20 SP67, 6.40 SP25, 7.00 SP21, 7.01 SP 06, 7.10 SP 09, 7.11 SP04

BR*Tools 7.10 Patch 24 and higherOracle 10.2.0.4 and higher

General SAP support of Partitioning Engine started with availability of above mentionedSupport Packages

Entry point for interested customers: SAP Note 1333328

SAP Partitioning Engine (in a nutshell)


New Oracle 11g Features supported byBR*Tools 7.20 (1)

Online conversion to new SecureFile LobsImplemented as new action ‘lob2lob’ within BRSPACE reorganizationLob compression can be activated with the same actionCan be done only ‘online’ (by redefinition), not offline (by move/alter)

Support for the new table compression ‘FOR OLTP’The feature can be activated during table reorganization by BRSPACETable and Lob compression can be enabled at the same time

Support for the new features of Oracle 11g Data PumpComplete compression of the data in export dump filesComplete encryption of the data in export dump filesExport of individual tables from different schemas

Tablespace compression and encryptionAllows to set compression and encryption attributes at tablespace level


New Oracle 11g Features supported byBR*Tools 7.20 (2)

New features in the area of data encryption (TDE)Changing the Wallet password using ‘orapki’ utilityOpening the Oracle Wallet in the database mount statusPassword protection for closing the Oracle Wallet

Improvement in database reset/PIT recovery using flashbackIncreases the reliability of the determination of archivelog files needed

Cleaning up new Oracle 11g trace files in diagnostic directoriesBased on new Oracle 11g parameter ‘diagnostic_dest’Aware of new Oracle 11g trace file types, e.g. incident files
