RMAN restore process for RAC environment

Figure 5. RMAN restore process for RAC environment

1
You define the restore job in the NetVault Backup WebUI.
2
Plug‑in for Oracle converts the job definition into corresponding the RMAN restore and recovery commands.
3
The RMAN reads the backup metadata from the Recovery Catalog repository.
4
The RMAN uses the Oracle Media Management API to read the backup from the backup device managed by the NetVault Backup Server.
5
The RMAN restores the datafiles to the Oracle server and recovers the database.

Licensing

Licensing of the plug-in in a single-instance, or non-RAC environment, differs from the licensing of the plug-in in a multi-instance or RAC environment.

•
In a single-instance environment, one Edition-Based Plug‑in for Oracle license lets you back up and recover an unlimited number of Oracle databases that reside on a single Database Server.
•
In a multi-instance or RAC environment, one RAC Database-Based Plug‑in for Oracle license lets you back up and recover a single database within the single RAC environment. This guideline applies no matter how many instances or nodes reside in the RAC environment. If you have five databases residing in the single RAC environment, purchase five RAC Database-Based Plug‑in for Oracle licenses, and so on.

Each RAC environment needs its own licensing. For example, if the production RAC environment has five databases and the test RAC environment has one database, five licenses are required for the production environment and one license is required for the test environment.

RAC configuration requirements

Plug‑in for Oracle’s support for multi-instance RAC databases is limited to environments that meet the following criteria:

•
The version of Oracle and the platform are listed as a supported RAC environment in Quest NetVault Backup Compatibility Guide.
•
Oracle Clusterware is used as the cluster software.
•
Datafiles, Control Files, SPFILE, Log Files, and Archive Log Files are stored on shared storage.
•
ASM File System is used for shared storage.
•
Control File Autobackups are enabled.
•
Recovery Catalog Database is the highly recommended location for the RMAN Repository.
•
Single or Multiple RAC databases within the same RAC environment are supported.

Figure 6 and Figure 7 provide an overview of supported single and multiple RAC database deployments.
