Oracle Database 10g certification at SAP

Ø All SAP products based on 4.6D kernel and later will be certified for 10g in Q4-2005 – Q1-2006

Ø Oracle 10g certification starts with SAP Business Suite 05 (ERP05, SRM05, SCM05)Ø 1. Step: Certification of Release 10.1 for BS 05 (10.2 comes

to late). BS 05 Ramp Up started end of October 2005.Ø 2. Step: Certification of Release 10.2 for BS 05 during Q4/05Ø GA of BS 05 with Release 10.2 only

Ø Validation & Certification of 46D_EXT and 6.40 kernel during Q1/2006

Ø Initial 10g certification does not include RAC

For current status please check OSS Note 720886


10g Features immediately supported by SAP

Instant Client Lite

Rename Tablespace

Online Segment Shrink

Auto Stats Collection

End to End Tracing

Online LONG to LOB Migration


10g Features to be supported later by SAP

Backup Compression

Full Database Begin Backup

Change-Aware Incremental Backup

Secured Redo Transmission

Data Pump

Cross-Platform Transportable Tablespaces

Flashback Technology

Recycle Bin

Automated Storage Management


Performance and Scalability

n Faster Drop and Truncate Tableu Using new hash mechanism for detecting dirty blocks in

database buffer cachel Less CPU usagel Less latch contention

u The more dirty blocks in buffer cache the higher the improvementsl Early tests show at least a performance improvement of factor 2

n In Memory Undou Information on block changes by short transactions have

been improved which results in less CPU usage

New Functionality with SAP BW 7.0 and 10.2


Performance and Scalability

n Improved Scalability for partitioned Objectsu Sharing Partitioning Metadata results in less SQL memory

usage in SGAl Example for one query on a table with 1,000 partitions:

9.2.0.6: 52KB10.2: 11KBImprovement by a factor of almost 5 !!!(Every query on this table will use 5 times less memory)



Installation and Maintenance

n Instant Client Liteu Easier deployment as only three Oracle client files are

needed for SAP kernel installationu Less memory neededu Oracle Client can be patched u Before: 10g SAP needed to provide a new kernel for any

Oracle client fix



§ New join and outer join syntax§ Switch to Ansi standard

§ Star query transformation on UNION ALL of E and F fact tables§ Oracle 10g allows SQT for views as well

§ No more drop/creation of views§ Views are completely replaced by From List Subqueries

(InLine Views)§ Reduced contention in system catalog

§ Less temporary tables used

§ Use of new SQL Merge command to move data from F into E fact table§ Rows with same key were aggregated -> compression

§ Use of Append Hint for direct load inserts§ Faster inserts and rollbacks

New DB Functionality in BW 7.0


Oracle 10g & RAC

§ Start with 1-2 10g RAC pilot projects after initial 10g certification in Q1/2006

§ Planned completion of pilot projects: end Q3/2006

§ Controlled availability of 10g RAC planned for end Q3-Q4/2006
