Defining a deployment strategy

Deploying Plug‑in for Oracle in a multi-instance database environment is almost identical to a single-instance database environment except that RMAN-based backups are the only available backup method for RAC databases. The plug-in is installed on one of the nodes that hosts one of the instances for the RAC-enabled database. All RMAN-based backups and restores are performed from this single installation of the plug-in. The following sections detail how the plug-in performs RMAN backups and restores in a RAC environment.

RMAN backup process for RAC environment

Figure 4. RMAN backup process for RAC environment

1	The user defines the backup job in the NetVault Backup WebUI.

2	Plug‑in for Oracle converts the job definition into the corresponding RMAN backup commands.

3	The RMAN executes the backup commands, which read data from the Oracle database datafiles.

4	The RMAN uses the Oracle Media Management API to store the backup on the backup device managed by the NetVault Backup Server.

5	The RMAN stores the backup metadata in 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 no matter the number of instances or nodes that reside in the RAC environment. If you have five databases residing in the single RAC environment, you must 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 RAC Database-Based Plug‑in for Oracle licenses would be required for the production RAC environment and one RAC Database-Based Plug‑in for Oracle license would be required for the test RAC environment.
