RAC

17

Real Application Clusters for SAP

18

One of Oracle’s main differentiators vs. other DB’s

for SAP customers:

Oracle Real Application Clusters (RAC)

• Removes database Server as Single Point of Failure

• All RAC nodes are active and serve production workload

• Enables a flexible way to scale applications using a simple scale-out model

• Servers can be added easily and dynamically without taking any of the active users offline

• Database is online as long as at least one node is still running

• Transparent and availabe for all kind (ABAP/JAVA) of SAP Applications

• Integrated clusterware and interoperated with HP Serviceguard Cluster

RAT

RAT for SAP

21

… …

Client Client

… Client

Capture DB Workload

Real Application Testing with

Database Replay

• Recreate actual production database workload in test environment

• Capture (10.2.0.4,5) workload in production including critical concurrency

• Replay workload in test with production timing

• Analyze & fix issues before production

Middle Tier

Capture SQL

• Test impact of change on SQL query performance

• Capture SQL workload in production including statistics & bind variables

• Re-execute SQL queries in test environment

• Tune regressed SQL and seed SQL plans for production

Middle Tier

Re-execute SQL Queries

Use SQL Tuning Advisor to tune

Real Application Testing with

SQL Performance Analyzer (SPA)

23

Real Application Testing

Benefits

• With RAT customers can capture and replay real

workloads, not synthetic or artifical loads.

• RAT provides 100% code coverage. It can replay 100%

of the orginal workload.

• Requires similar effort for small and large

captures/replays.

• Allows to proactively detect problems and to find

solutions in a testing environment before changes in the

production enviroment are made. E.g. during upgrades

or after applying patches.

• Reduces costs for testing significantly

24

Real Application Testing

Benefits

• RAT works with Single Instance and Real Application

Clusters (RAC)

• Workload can be captured in Oracle 10gR2 (10.2.0.4)

and replayed in Oracle 11gR2.

• Workload replay does not need to be done on the

same OS platform.

• Capturing adds only very low additional workload on

the system that is being captured (<5%)

Data Guard for SAP

27

Data Guard Redo Apply

Physical Standby Database is a block-for-block copy of the primary database

Uses the database recovery functionality to apply changes

While apply is active can be opened in read-only mode for reporting/queries*

Can also be used for fast* backups, further offloading the production database

28

Data Guard for SAP

• You can use "Physical Standby"

• You cannot use "Logical Standby"

• You can use Data Guard Broker

• You can use

– Maximum Performance Mode

– Maximum Availability Mode

– Maximum Protection Mode

29

• Use Standby Database for testing

and development

– Eliminates cost of DR

– Justify full scale test and DR

environments by combining into one

• Preserves zero data loss while in

test/dev mode

– But no real time query or fast failover

• Similar to storage snapshots, but:

– Provides DR at the same time

– Single copy of storage

Kompresia

31

Storage Efficiency: Technology Stack

• Most efficient storage of data

– Number values

– Bitmap Index

• Most comprehensive set of

compression options

• Combination with other Data-

base Options (Partitioning)

increases advantages

• Easy administration

(e.g. reduction of reorga-

nizations required)

Advanced Compression (Oracle 11g)

Partitioning + Compression (Oracle 10g)

Index Key Compression (Oracle 10g)

Data Compression (Oracle 10g)

Efficient Data Storage

• Deffered Tables

32 32

• Advanced Compression

– OLTP Table Compression (on data block level)

– RMAN Backup Compression – Unique to Oracle

– Expdp Compression

– Data Guard Network Compression – Unique to Oracle

– SecureFile Compression for in-line and out-of-line LOB data

• Unique to Oracle for out-of-line LOBs (DB2 can only do in-line

compression).

• Out-of-line LOBs are more used than in-line LOB data in SAP

products such as

– SAP CRM

– SAP XI

– SAP Portal

– SAP R/3 (almost all non-cluster tables use out-of-line LOBs

Oracle Database 11g R2 Advanced Compression

• Adaptive and continual compression

• Compression runs automatically after PCTFREE reached

• Compression eliminates holes after DELETE operations and maximize data block utilization

• SAP kernel 6.4, new install 7.0

Advanced Compression Option for SAP

Advanced Compression Option Performance

37 37

1. Start with Index compression for the n largest tables

(100<n<500)

2. Migrate all SAP transparent tables (except queue type

tables like VB or RFC tables) to oltp compressed tables

3. Migrate all LOBs of SAP tables (except cluster, pool and

INDX tables) to compressed securefiles

• CREATE TABLE COEP (...) COMPRESS FOR OLTP;

• ALTER TABLE COEP (...) COMPRESS FOR OLTP;

• CREATE TABLE DYNPSOURCE (...) LOB (FIELDINFO) STORE

AS SECUREFILE (COMPRESS MEDIUM);
