Installation prerequisites
The following prerequisites must be met before you install Plug‑in for Oracle in a clustered environment:
|
• |
Oracle® Failover clustering environment in place: You must have a properly configured Oracle Cluster environment. |
|
IMPORTANT: Support for this feature was tested on Windows Server® using the Oracle Fail Safe Clustering feature and employing a two-node Oracle (v6.5) cluster configuration with shared storage containing the database data files and logs. If you intend to use clustering in a different configuration, test backups and restores before deploying it in a production environment. |
|
• |
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 Server cluster, but have network connectivity to the nodes (hosts) within the cluster. |
Installing or upgrading the software
Installation of the plug-in for a clustered environment is different than the traditional installation of this plug-in. This process is completed through the creation of a Virtual Client on the NetVault Backup Server. A Virtual Client is a group of nodes within the cluster that are seen by the NetVault Backup Server as a single client that is created to back up a single clustered service.
Creating a Virtual Client
As noted earlier, the Virtual Client creation process is not plug-in-specific, and you can find complete details in the Quest NetVault Backup Administrator’s Guide. However, consider the following points during the Virtual Client creation process:
|
• |
Assign a name to the Virtual Client: Quest recommends that you use the virtual-network name assigned to the Oracle® Database as the NetVault Backup Virtual Client name; you can also use a name that is easily associated with the Oracle Database or cluster environment. This configuration makes it easier to recognize the Oracle Database for which the NetVault Backup Virtual Client was created. |
|
• |
Only include relevant cluster nodes in the Virtual Client: The hosts that are to be included in the creation of a Virtual Client should only be those nodes within the cluster that are relevant to the Oracle Database Server that is to be backed up and restored. |
After the creation of the Virtual Client, the plug-in is transferred to all designated cluster nodes and installed locally. You can use the installed Plug‑in for Oracle by using the Virtual Client to back up and restore shared data; you can only perform backups and restores of data established as shared within the cluster.
Licensing the plug-in
Another difference between using Plug‑in for Oracle in a clustered environment is how it is licensed for use. The plug-in supports backup and restore of shared data only. Hence, for an Oracle® Database Server Failover Cluster environment, only a single license would be needed — a clustered application license for the Virtual Client.
For information on the licensing process, including how to obtain the proper license keys, see the Quest NetVault Backup Installation Guide.
