OEM 10.2.0.5 is the way to go◦ Many fixes

◦ Stable release

If using older release◦ Check Metalink for (many) fixes

Task automation◦ Reduction of complexity

Usage of simple Wizards

◦ Reduction of costs

Use highly skilled DBA’s for more complex tasks

◦ Time to Market

Configure Clusters, Servers in matters of hours instead of days

◦ Standardization

Standardized Components (SWL), Baselines etc.

Standardized Procedures

Software Library◦ Provisioning Backbone

◦ Partially in Repository

MGMT_PAF…

MGMT_SWLIB…

Software Library◦ Partially on OMS file system

At configuration time

SWL configuration that is...

If multiple OMS’s are used

SWL needs to be located on a shared file system

Components◦ Files◦ Golden Images Oracle Clones, CRS, ASM, DB

◦ Baselines◦ (Ingredients)

Directives◦ Logic Scripts: Perl - shell

◦ What to do with … (Component)◦ (Recipes)

Networks◦ Network definitions - BMP

Images◦ Bundle of Components, Directives◦ Used for BMP

Suites◦ Collection of heterogeneous components,

grouped together◦ Example: Oracle Collaboration Suite (database,

application server, Web server, and an Identity server )

Suite Instances◦ Group of Hardware Servers that will run each of

these components (Suites)

Assignments◦ Provisioning of an Image or a Suite of Images on a

Server

Hardware◦ Hardware specification

Cluster◦ Specification of Hardware Servers in a Cluster◦ BMP

Administration◦ Configuration of Software Library

Use Case◦ Setup Cluster (Let’s pretend we have...)

Installed OS

Configure based on Best Practice / Pre-Requisites

Installed Agent

◦ Setup Oracle Software

Installed CRS Software + Configuration

Installed ASM Software + Creation of ASM Instance

Installed DB Software

◦ ... and this what we want to do (Requirements)

◦ Create RAC Database

Nodes to create Instance on based on user input

Apply CPU

Apply Company specific settings

Register in OEM

Create some default RAC Services

Register in OID (Oracle Internet Directory)

Assign privilege to Administrators via Role in OEM

Apply Monitoring Template (< 10.2.0.5)

Setup TMS (Tape Management System)

Perform 1st Backup

Use Case◦ Run “Out of Box” Procedure

Oracle Clusterware / RAC Provisioning

Used to do the CRS / ASM / DB Software part

◦ Characteristics Starter (RAC) Database – 1 Instance in each node

Listener Port 1521 (Want Port 39000)

Uses Disk group DATA (Want this to be variable)

Missing requirements previously mentioned

Use Case◦ Solution:

Customize “Out of Box” ProcedureOracle Clusterware / RAC Provisioning

Create custom Procedure to create RAC Database

Create custom Procedure:Create RAC Database

Base on “Patch Oracle Database”◦ Type 2, so customizable GUI

Create like…◦ Unable to modify “Out of Box” procedures

Need one Directive ◦ Related to script that will create the database

Need one Directive◦ From scratch or,

Based on existing script

runDatabaseConfigTools.pl (Out of Box)

Upload the custom Perl script to the Directive

Activate the Directive

Create like…

Delete all steps…

Insert new Step… (Phase)

◦ At the same time:

Latest CPU got applied

Registration in OEM completed

Groups, Services

Some default RAC Services created

Database, Instances, Services registered in OID

Privileges were assigned to Administrators

Monitoring Template were applied (< 10.2.0.5)

TMS Setup completed (Tape Management System)

1st Backup has been run
