Adding an On-Demand Instance for Oracle RAC

You can create an on-demand instance to perform Oracle RAC database backup operations for a specific purpose. These backup operations are run on an "as needed" basis. Use customized RMAN scripts to run backup operations for on-demand instances.

When you create an on-demand instance, a default subclient is automatically created for that instance.

Note

After you create an on-demand instance, you cannot change it to a traditional instance.

Do not create on-demand instances to run maintenance scripts. Instead, run third-party command line jobs to perform maintenance operations.

Procedure

  1. Enable on-demand instance creation for Oracle RAC in the CommCell Console if you have not done that yet. For more information, see Enabling Oracle RAC On-Demand Instance Creation in the CommCell Console.

  2. From the CommCell Browser, expand Client Computers > client > All Tasks, and then click New On Demand Instance.

    A dialog appears to ask if you are sure you want to create an on-demand instance.

  3. Click Yes to confirm the creation of an on-demand instance.

What To Do Next

You can run on-demand backup operations using qoperation commands.
