2. This Presentation… Is pretty technical
Includes several (many) Screen dumps
Covers OEM –
Gives you an insight overview of: How to … / How it works
Is about how we do this at Rabobank

3. Agenda Previously at Rabobank… Requirements Database in ECO
Out of the Box procedures
Customize Directive
Customize Deployment Procedures
In the meantime, think about…
Q & A

4. Previously at Rabobank
“Manual” Database creation
Run Database creation script
Configure TSM – File System
Discovery of Database in OEM
Assignment to Monitoring Group
Assignment of Monitoring Templates
Assignment to Role
Configure Backup
Include in Backup Job

5. Previously at Rabobank
2 – 3 Hours to complete
High risk of Human Errors
Very hard to force Standards

6. Requirements Database in ECO
On pre-configured Stack
Provisioning of Clusterware – ASM – DB
1..n Nodes
Standardized – 1 Preferred – 2 Available
Specific Disk Group to be used
Development – Test
1 “Large” Disk Group
Production
Based on Security Category
1 per Application

7. Requirements Database in ECO
Application of EM Monitoring Templates
Cluster Database
Database Instance
Assign access Privilege – Role
All necessary Target Privileges are assigned to Role
Inclusion in Backup Job
By assignment to Group
Creation of 2 default RAC Services
SRV<DatabaseName>ORA
SRV<DatabaseName>RMN

8. Requirements Database in ECO
Registration with OID
Database Unique Name
Database Instances
RAC Services
Listeners were registered in earlier phase
Registration with OMS
Cluster Database

9. Out of Box Procedures Oracle Database Provisioning
Single Instance Database
Hard to customize / to modify GUI
(Use EMCLI to execute DP)
Oracle Clusterware – RAC Provisioning for Unix
Starter Database
Not very efficient

10. Customize Deployment Proc
2 Types of Procedures (Database Deployment)
RAC Provisioning Procedures
Patch Procedures
Impossible to modify GUI
Impossible to modify GUI, except for one….
Patch Oracle Database

11. Customize Deployment Proc
General Structure
Software Library
Components
Deploy Software Library Component and associated Directive
Directives
Logic
Scripting
Shell
Perl

12. Customize Deployment Proc
Create custom Directive
Upload customized script
Start with Patch Oracle Database Procedure
Delete all Steps
Create ‘Rolling’ type Phase
Creation Database initiated from 1st Node
Create Step within the Phase
Create RAC Database and Instances
Map Properties
Run Procedure

13. Customize Directives Contains Arguments Static value
Entered by User at runtime
Script
Containing the actual logic

19. Next
Customize the Deployment Procedure

35. In the meantime, think about…
Development / Test Environment
Production Environment
Deployment of Deployment Procedures ;-)

Perl knowledge

40. Wrap Up
Creation of RAC Database and completion of all necessary tasks in 20 Minutes instead of 2-3 Hours
Task automation
Fully standarized
Multiple executions at the same time
