Configuring default attributes

•
NetVault Backup (required for RMAN backups in a RAC environment): Specify the name of the NetVault Backup Server where the Oracle Database Server was added as a NetVault Backup Client.
•
Do Restores from NetVault Backup Server (required for RMAN backups in a RAC environment): Specify the name of the NetVault Backup Server where the Oracle Database Server was added as a NetVault Backup Client.
•
CLI Backup/Autobackup Target Set (required for RMAN backups in a RAC environment): Specify the name of the Backup Target Set that was specified in the Configuring a default Target Set for RMAN backups.

Determining the local Oracle SID and Home directory in a RAC environment

In a multi-instance RAC environment, the local SID and Oracle Home can be determined with the srvctl config database commands.

1
From a terminal window, connect as the Oracle Software Owner to the node where plug-in is installed.
2
Run the following command:
srvctl config database
A list of all databases in the RAC environment is displayed.
3
Run the following command, where <database_name> represents the database that is being added to the plug-in:
srvctl config database -d <database_name>
The name of the node, local Oracle SID, and local Oracle Home are displayed for each node in the RAC environment in the format:
<node> <local Oracle SID> <local Oracle Home>

In the following example, Plug‑in for Oracle is being installed on the “faro” node, the local Oracle SID is “o10rac3,” and the local Oracle Home is “/home/o10g/db.”

Example
faro:/home/o10g => srvctl config database
o10grac
o10rac
faro:/home/o10g => srvctl config database -d o10rac
lisbon o10rac1 /home/o10g/db
evora o10rac2 /home/o10g/db
faro o10rac3 /home/o10g/db
faro:/home/o10g =>

Adding a database to the plug-in

Adding a multi-instance database in Plug‑in for Oracle is almost identical to adding a single-instance, non-RAC database except for the following differences:

•
Oracle SID: Enter the local SID for the target RAC database. The local SID is the instance name for the target RAC database on the node where the plug-in is installed.
•
Parameter File(s) Path: In a multi-instance RAC environment, the plug-in requires the usage of an SPFILE as a dynamic method of maintaining initialization parameters. The SPFILE must be stored on the shared storage in ASM. Because the SPFILE is included in the Control File Autobackups, this field should be left blank in a RAC environment.
•
Control File Autobackup enabled: Select this option because Control File Autobackups are required in a RAC environment.

For more information, see Configuring the plug-in.

Backing up data

RMAN-based backups are the only supported backup method for multi-instance RAC databases. RMAN is RAC-aware in that it automatically identifies that a database is a multi-instance RAC database and backs up the selected data accordingly.

With the plug-in 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 Parameter File node is not selectable on the NetVault Backup Selection page.

For more information on selecting data for backup, setting backup options, and finalizing and submitting the job, see Performing RMAN backups.
