• Oracle Clusterware / RAC Provisioning for UNIX

• Installs

• CRS

• ASM

• DB

• Allows you to

• Create + ASM instance

• Create starter Database

15


• Consists out of 43 Steps

• Allows the source to be:

• Existing OracleHome

• Software Library

• Use Software Library!

• Central located baselines

• CRS / ASM / DB

16


• Enable notification (see next slide)

• 10.2.0.4

• Results in e-mail message like:

• Subject 45.Attention.Step.Failed

• No message text

• 10.2.0.5 Not tested yet

• Should be fixed

19


• Notice that: (see next slide)

• each step can be:

• Edited

• Enabled

• Disabled

• Removed

• Step outcome

• Can be inherited

• Ingnore

21


• We don’t use Create Starter Database (See next slide)

• We use a separate DP Procedure for this

• Create RAC Database on configured Stack

26

• ASM Disk String

• /dev/mpath/36* not allowed

• No use of wildcards

• 10.2.0.4

• 10.2.0.5 Not tested yet

• Should be fixed

28


• Procedure takes 2 – 2 ½ hours

• Includes +/- 22 Steps – “Checks and Fixes”

• Takes +/- half of processing time

• Doesn’t make sense if target platform is guaranteed the same

• Was configured with same image – BMP

• Split the Out of Box procedure

• Just checking

• To be used when BMP image changes

• Do the actual job

• Reduces processing time to approx 50 Minutes33

Customizing – DP Procedure

• New procedure with Create Like

• Unable to edit the Out Of Box procedures!

• So Create Like and then edit

34

Customizing – DP Procedure• Requirements

• Diskgroup to be used

• Default DATA

• We use DGO, DGT… (Development, Testing,…)

• Listener port

• Default 1521

• We use 39000

• We use one Listener per Server

• Network Admin

• Default $ORACLE_HOME/network/admin

• We use /u01/app/oracle/admin/network/admin

• Shared for server35


• Software Library

• Components

• Directives

• Oracle Directives

• RABO Directives

36


• Make new “RABO” Directives

• RABO – Run Oui Only Prerereqs

• Based on Run Oui Only Prerereqs

• runOuiOnlyPrereqs.pl copied to raboRunQuiOnlyPrereqs.pl

• then make modifications

• RABO – Run ASM Config Tools

• Based on Run Database Config Tools

• runDatabaseConfigTools.pl copied to

raboRunASMConfigTools.pl

• then make modifications

38


• Next, edit the procedure

• Rabo – CRS / ASM / DB Provisioning

• Edit steps you want to modify

• In this example:

• Verify Prerequisite Checks

• Run ASM Configuration Tools

43

Customizing – DP Procedure• Save the modifications

• Start testing

• Notice that when running a DP procedure

• When a Step fails – because of Input typo

• Do an update and retry or…

• Ignore the failure and proceed

• Check /u01/app/oracle/product/10.2.0/agent10g/EMStage/PA

F/Job_59beb3609b747a3fe04048914d0a3729 (this should be

the most recent directory that is present in the ../../PAF directory)

• outputFile

Wrap-up• It does work!

• Make sure you have your requirements

• Start testing the Out Of The Box procedure

• Enhance the Software Library for custom Directives

• Create your customized Directives

• Create your customized Procedure

• Edit the Procedure Steps you want to customize

• Assign the new created Directive

• Configure how the Directive Arguments should be processed

• Ask User at Runtime

• Choose Variable

• Set Value 47
