7 New Oracle Patch Concept: Patch Set Updates (PSUs) This only affects Unix/Linux-platforms! Windows platforms are not affected. Starting with Oracle patchset Oracle provides socalled Patch Set Updates (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 SAP 2010, Development Update SAP on Oracle, Page 7

8 New SAP/Oracle Patch Concept: SAP Patch Bundles & Patch Set Updates (PSUs) Oracle database patches for Unix-platforms are now delivered in form of socalled SAP Bundle Patches (SBP) Initial Oracle versions: & 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 the new patches in addition. Notation of SBPs: SAP_<Oracle-version>_<YYYYMM>_<plattform>.zip Example: SAP_102044_201004_AIX.zip For the installation you'll need MOPatch Version or higher For more details please see SAP note SAP 2010, Development Update SAP on Oracle, Page 8

17 11g News for SAP Oracle Feature Availability (with 11.2 SAP GA) Space (V) Implementation Guidelines for Compression Technologies in SAP Environments 1. Start with Index Compression - Improves R/3 Performance the most as all database access in R/3 environments is index based, especially index range scans - Up to 20% disk space reduction for complete database 2. 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 already compressed) SAP 2010, Development Update SAP on Oracle, Page 17

18 11g News for SAP Oracle Feature Availability (with 11.2 SAP GA) Performance (I) 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 SAP VBDATA Throughput (Insert/Read/Delete) Performance Improvement Factor 2,5 2 1,5 1 0, row size in KB LONGs (9.2,10.2) LOBs (10.2,11.2) Securefiles 11.2 SAP 2010, Development Update SAP on Oracle, Page 18

25 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/or tables is a time- and resource-critical process Range partitioning can be used to separate historical and current production data in order to minimize the above impacts Problem: Application tables usually do not have a direct time dependent column in the primary key An alternative is to use an indirect time related column like document number, which exists 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 with Oracle Table Redefinition package, but this is not a simple admin task SAP 2010, Development Update SAP on Oracle, Page 25

26 SAP Partitioning Engine (in a nutshell) 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 partitioned based on time based criteria Existing non-partitioned tables will be converted through ABAP/SAP BR*Tools task Partition Maintenance is fully automated through internal SAP SM37 job (no need for DBA intervention) Prerequisites SAP systems based on 6.20 WebAS release and higher. Examples: SAP ECC 5.0, ECC 6.0, Business Suite 7 Requires 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 higher Oracle and higher General SAP support of Partitioning Engine started with availability of above mentioned Support Packages Entry point for interested customers: SAP Note SAP 2010 Development Update SAP on Oracle, Page 26
