General Availability Oracle RAC

Ø General Availability (GA) for RAC was announced by SAP in early January 2009

Ø No SAP/Oracle approval process for RAC projects required anymoreØ GA is valid for Oracle versions 10.2.0.4 and higherØ Configuration requirements as defined in SAP note 527843 still stay in place

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

Ø Oracle Clusterware solution SAPCTL for protecting SAP Enqueue Server

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

Ø Overall we currently have ~80 SAP customers successfully productive on RAC.

For details regarding RAC certification please see SAP note 527843

Virtualization Support

Ø Oracle does not support VMWare & XEN for productive SAP environments

Ø No existing support relationship between Oracle and corresponding vendors

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

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

Ø Metalink note 249212.2 is not valid for SAP systems


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

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

Ø Support for those products is fully ensured by existing support contracts between Oracle and OS vendor

Motivation:

Ø SAP promotes use of Unicode in future versions

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

Ø Customers can only afford limited downtime of their production system for the data migration phase

Achievements:

Ø Improved Table Split and R3load throughput for export and import phase

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

Ø Use of Optimizer Hints to force optimal access path

Ø Uses partitioning concepts of SAP BW and R/3

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

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

Ø 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

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

Ø ROWID table splitting dramatically reduces CPU and IO resources during export

Ø R3load export times up to 3-5 times faster

Real World AIX Customer Example:

Ø Complete export and import time for 2 Terabyte database was 2 hours 15 minutes

Ø To achieve this appropriate high end hardware required

Upcoming Optimization for Cluster Tables and R3load

Ø Goal: More than 1 Terabyte / Hour throughput

Partitioning Engine

DBA Tools


Partitioning Tools for SAP/Oracle non-BI systems

Motivation

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

Ø Archiving is a continuous process and generates significant system load

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

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

Ø Problem: Application tables usually do not have a direct time dependent column in the primary key

Ø 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

Ø Defining suitable ranges based on document number is difficult

Ø 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


New SAP ‘Partitioning Engine’

Ø New ABAP and BR*Tools based partitioning ‘engine’ to performance optimize SAP archiving

Ø Applicable to a set of ~ 40 predefined SAP application tables

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

Ø ‘Partitioning engine’ will be made available starting with WEB AS 6.20

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

Ø Customer piloting during Q2/2009

Ø GA planned during Q3/2009


Description of Partitioning Engine (Part 1)

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

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

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

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

Ø Analysis task can be done even on very large tables in less than 1 hour

Ø Partitioning is a multiple column partitioning with at least client and document number column (#NRIV)

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

Select table to apply partitioning



n Second part of partitioning engine is a new function in the „BRSPACE“ tool, which reads the previously created DDL statement und performs the online redefinition Ø Automatic Long -> LOB migration if table contains Long field

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

brspace command



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

Ø The ABAP program creates additional spare partitions within the table if necessary using fast partitioning split

Ø The ABAP program merges nearly empty partitions which remain after archivingØ By merging partitions unused space gets released

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

Ø Still significant improvement compared 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:')

MOPatch - Install Multiple Oracle Patches

Motivation for MOPatch:Ø 10.2 based SAP systems require additional number of Oracle one-off patches. To apply them

may be a time consuming and error-prone task.

Features of MOPatchØ Reduces installation and maintenance time for 10.2 based SAP systemsØ Simplifies the installation and guarantees the correctness of necessary patches to be applied –

Ø Easy two step process: 1. Download all patches from SMP 2. Apply all

Ø Automates the process of unpacking and applying the patches and eliminates the need for userinteraction

Ø Detects and handles appropriatelyØ • zip file errors • patch conflicts • warningsØ • errors • fatal errors

Ø Provides a concise execution summaryØ Collects patch READMEs and removes repeating template text, reducing them in size by

factor 5 – 6Ø NEW:

Ø Full support for existing installations not just new installations – Fully manages the delta of existing and new patches

Ø Cleanup Functionality – Reduces Disk Space Requirements
