Installation prerequisites
The following prerequisites must be met before you can install Plug‑in for Oracle in a RAC environment:
|
• |
Oracle RAC environment in place: You must have a properly configured Oracle RAC environment that matches the configuration as specified in RAC configuration requirements. |
|
• |
Separate NetVault Server machine: The machine that is to serve as the NetVault Server must be properly configured. This machine must exist outside the Oracle RAC environment, but have network connectivity to the nodes and hosts within the RAC environment. |
|
• |
Separate Recovery Catalog Server: Quest recommends that you store the RMAN repository in a Recovery Catalog database on a server outside the Oracle RAC environment. For more information, see Creating the RMAN repository. |
|
• |
Additional prerequisites: In addition to the preceding RAC-specific requirements, meet the requirements that are specified in Prerequisites. |
|
• |
Oracle 11g Release 2 and later: If you are using Oracle 11g Release 2 or later, ensure that the snapshot Control File is shared by all nodes in the RAC database. The snapshot Control File must be saved in a shared location, such as in one ASM instance or on a shared drive. The location of the snapshot Control File is managed by the snapshot Control File name RMAN parameter. In Oracle 11g Release 2, by default, this parameter refers to a persistent file in the local file system on each of the RAC nodes. If this configuration applies to your environment, ensure that you change the parameter to point to a shared location. Otherwise, RMAN backups that include the Control File might fail with an “ORA-00245: control file backup operation failed” message. |
Enabling Control File Autobackups in a RAC environment
Control File Autobackups are required in a RAC environment. For more information, see Reviewing the Control File backup types. For more information on single-instance RAC databases, see Enabling Control File Autobackups.
Installing or upgrading the plug-in
Installing Plug‑in for Oracle in a multi-instance database environment is almost identical to installing it in a single-instance database environment. 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. Installing the plug-in is a two-step process:
During installation of the NetVault Client software on the selected node of the RAC environment, a name that represents the entire RAC environment should be specified as the NetVault Machine Name versus the machine name of the selected node. For example, if the machine name for the node where the NetVault Client software is being installed is called RAC_NODE_1, RAC_NODE_1 should not be specified as the NetVault Machine Name; it should be a generic or virtual name that represents the entire RAC environment such as PROD_RAC.

Configuring the plug-in
Configuring Plug‑in for Oracle in a multi-instance RAC environment is almost identical to configuring the plug-in in a single-instance, non-RAC environment except for the items identified in the following topics.
