Motivation

SAPinst Oracle 11.2 Backward Release

Runtime release Oracle 11.2 created approx 6 months ago

System copy to Oracle 11.2 is only possible with the backward

releases

Very high logistical effort (approx.15 inst masters with 40 products)

Oracle 11.2

Disk space and I/O optimization by table compression and index

compression

Automatic storage management ASM

Deferred segment creation

– 60-70% of SAP tables are empty

Database file system (open)

Exadata, Oracle Enterprise Linux (open)

Tablespace – compression

Tablespace compression via Advanced DB Configuration

Only for DB server version 11.2

• DB on raw device is

not supported as of 7.3

Compression - SecureFile

SecureFile handling at SAP

Oracle 10.2: BasicFiles (CLOBS, BLOBS) are still created

Oracle 11.2 without table compression: BasicFiles are still created

Oracle 11.2 with table compression: SecureFiles are created

– SAP standard: table compressed -> SecureFile compressed

– SecureFile compression medium

– Available with Oracle Advanced Compression option

Indexes are not compressed

Changes can be made via online reorg or with BRSPACE functions

System Copy SMIGR_CREATE_DDL

SAPinst Compression - SecureFile

AusblickAutomatic Storage Management ASM ab Netweaver 7.03Dual Stack Split ab Netweaver 7.03, 7.30

System Copy –

SMIGR_CREATE_DDL

ABAP report executable on the source system

Must be executed on the source system before every export

Creates R3load SQL files for Oracle partitions (BW systems)

Creates R3load SQL files for exception lists (table compression)

ABAP: “copy as it is”

Report attempts to build the target system as an identical copy of the

source system

Java: “standard”

There is so far no SAP DDIC information on the compression of

tablespaces or tables

Changes in SAP Installation

New user oracle

New groups oinstall, asmadmin, asmoper, asmdba

ASM software and also database software are installed as user

oracle:oinstall

Two ASM groups (+DATA und +ARCH) are recommended

ASM: available as of Netweaver 7.03

Oracle files in ASM

Tablespace data files in +DATA

Control file, spfile, and redolog files in +DATA

Oracle archive files in +ARCH

– Raw device installations are no longer supported

Dual-Stack Split

Dual-Stack Split

Installation ABAP & Java dual-stack installation no longer possible as

of 7.02

ABAP & Java instances receive their own SID

The Oracle database schema is unchanged

SAPinst separates the Java instances from the ABAP instance by:

– Deletion of the Java instance and recreation of it with a new SID

– Export of the Java schema and import to another server
