Glossary
Licensing
|
• |
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, you must purchase five RAC Database-Based Plug‑in for Oracle licenses, and so on. |
To request permanent RAC Database-Based Plug‑in for Oracle license keys, go to https://support.quest.com/licensing-assistance.
Installing the plug-in in a RAC environment
Before completing any additional or different steps that are outlined in this section, review the information provided in earlier sections, such as Installing and removing the plug-in and Configuring the plug-in.

The version of Oracle® and the platform are listed as a supported RAC environment in Dell NetVault Backup Compatibility Guide. |
Figure 6 and Figure 7 provide an overview of supported single and multiple RAC database deployments.

Installation prerequisites
|
• |
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 Backup Server machine: The machine that is to serve as the NetVault Backup 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: Dell 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, you must meet the requirements that are specified in Prerequisites. |
|
• |
Oracle 11g Release 2 and later: If you are using Oracle 11g Release 2 or later, you must 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. |
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 the plug-in
|
1 |
Install the NetVault Backup Client software. |
During installation of the NetVault Backup 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 Backup 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.
