Genaral Availability Oracle RAC

General Availability (GA) for RAC was announced by SAP in early January 2009No SAP/Oracle approval process for RAC projects required anymoreGA is valid for Oracle versions 10.2.0.4 and higherConfiguration requirements as defined in SAP note 527843 still stay in place

RAC 10.2 is certified for all SAP Products based on 4.6D_EXT ff.

Oracle Clusterware solution SAPCTL for protecting SAP Enqueue Server

No support for Raw Devices and ASM (ASM planned in 2011)

Overall we currently have ~60 SAP customers successfully productive on RAC.

For details regarding RAC certification please see SAP note 527843


Oracle RAC 10.2.0.4 News

AIX 5.3 and 6.1Support for GPFS 3.2

Improved Failover, Faster Recovery, 255 filesystems

Linux – RHEL 5.2 and SLES10 SP2Support for OCFS2 1.4

Online Resize, mmap, sparse Files, Data in inode, local mounts, freeze/thawIntegration with Cluster LVM to support stretched clusters

SAPCTL (Clusterware Solution for SAP HA) EnhancementControl of SAP Message Server as a separate entity


Virtualization Support

Oracle does not support VMWare & XEN for productive SAP environments

No existing support relationship between Oracle and corresponding vendors

Oracle does not plan to change support status in the near- to midterm future

Use of VMWare or XEN in non-productive SAP environments is supported

Metalink note 249212.2 is not valid for SAP systems

For details please see SAP note 1173954

Oracle plans to support the native OS/hardware vendor virtualization products

HP Integrity VM, WPAR AIX, Sun VM, Hyper V for Windows, …..

Support for those products is fully ensured by existing support contracts between Oracleand OS vendor


Agenda

Motivation:

SAP promotes use of Unicode in future versions

Migration of an existing SAP system to Unicode requires a complete export and import of thedatabase through SAP R3load utility

Customers can only afford limited downtime of their production system for the datamigration phase

Achievements:

Improved Table Split and R3load throughput for export and import phase

NEW – Advanced ROWID Table Split functionality allows data to be read in physical order from disk

Use of Optimizer Hints to force optimal access path

Use of OCI Direct Path Interface instead of SQL Inserts for R3load

Use existing system resources (CPU, Memory, IO) more effectively through Parallel Query,Parallel Index Creation and Automatic Index Statistics Calculation

Optimizations available for 6.40 and 7.00 based SAP systems with Oracle 9.2 and Oracle 10.2



New ROWID table splitting functionality available for transparent tables

ROWID ranges for a table are being calculated in less than 30 seconds – Calculation timeis independent from the table size

ROWID table splitting dramatically reduces CPU and IO resources during export

R3load export times up to 3-5 times faster

Real World Customer Example:

Complete export and import time for 6 Terabyte database was 10 hours

To achieve this appropriate high end hardware required

Upcoming Optimization for Cluster Tables, BW Systems and R3load

Goal: More than 1 Terabyte / Hour throughput

MOPatch - Install Multiple Oracle Patches

Motivation for MOPatch:10.2 based SAP systems require a larger number of Oracle one-off patches. To apply them is atime consuming and error-prone task.

Features of MOPatchReduces installation and maintenance time for 10.2 based SAP systemsSimplifies the installation and guarantees the correctness of necessary patches to be appliedAutomates the process of unpacking and applying the patches and eliminates the need for userinteractionDetects and handles appropriately

• zip file errors • patch conflicts • warnings• errors • fatal errors

Provides a concise execution summaryCollects patch READMEs and removes repeating template text, reducing them in size by factor5 – 6NEW:

Full support for existing installations not just new installations – Fully manages the delta ofexisting and new patchesCleanup Functionality – Reduces Disk Space Requirements

Partitioning Tools for SAP/Oracle non-BIsystems

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


New SAP ‘Partitioning Engine’

New ABAP and BR*Tools based partitioning ‘engine’ to performance optimize SAParchiving

Applicable to a set of ~ 40 predefinded SAP application tables

A partitioning service for non-BI SAP systems is offered by Oracle since a while, butup to now was not integrated into SAP’s DB admin tools

‘Partitioning engine’ will be made available starting with WEBAs 6.20

Next 6.20, 6.40 and 7.00 support packages will contain this feature

Customer piloting during Q2/2009Interested customers are still invited

GA planned during Q3/2009


Description of Partitioning Engine (Part 1)

First part is an ABAP program, which analysis the content of the document column of an application tableand creates as output a DDL statement for the table and indexes with suitable partition ranges

Analysis of document column is done with the help of the underlying number-range object defined intable NRIV -> “NRIV Partitioning”

For each NRIV number range a series of partitions with equal size (2GB – 20GB, depending on tablesize) is generated including empty spare partitions for each number range with precalculated borders.

The DDL statement also generates a max partition that is always empty (latter is necessary for laterfast partitioning split)

Analysis task can be done even onvery large tables in less than 1 hour

No full table scan, instead jumpingin calculated increments through rows

Partitioning is a multiple column partitioningwith at least client and document column(#NRIV)

Additional columns can be part of partitioningkey if number range is year dependent (MSEG)or contains sub objects (COEP) or both (BSIS)

Select table toapply partitioning



Second part of partitioning engine is a new function in the „BRSPACE“ tool, which reads thepreviously created DDL statement und performs the online redefinition

Automatic Long -> LOB migration if table contains Long field

BRSPACE required because online redefinition must run as user ora<sid> (sys)

brspace command



Third part is an ABAP program which runs in batch (SM37) for maintaining the tablepartitions

The ABAP program creates additional spare partitions within the table if necessary usingfast partitioning split

The ABAP program merges nearly empty partitions which remain after archivingBy merging partitions unused space gets released

During merge indexes are not usable(~ minutes for local indexes, global indexes take longer)

Still significant improvementcompared to a full table reoganization


PARTITION BY RANGE ("MANDT","DOCNUM")(

….PARTITION "EDIDC_800_01_00001" VALUES LESS THAN ('800','0000000000400001'),PARTITION "EDIDC_800_01_00002" VALUES LESS THAN ('800','000000000800001')…PARTITION "EDIDC_800_01_MAX" VALUES LESS THAN ('800','999999999999999:')
