In an Oracle RAC environment, it is recommended that you assign one node to be the preferred backup node for Oracle centralized backups. You can assign the preferred backup node by setting an asset-level option in the
PowerProtect Data Manager UI.
About this task
An update of
PowerProtect Data Manager from a previous version automatically migrates a
RAC_BACKUP_NODE_IP parameter setting in the configuration file to the preferred node setting on the
Assets page in the
PowerProtect Data Manager UI. If you later modify the preferred node setting in the UI, the UI setting takes precedence over the original parameter setting in the configuration file.
NOTE:
The preferred node setting in the
PowerProtect Data Manager UI takes precedence over a
RAC_BACKUP_NODE_IP parameter setting in the configuration file for the same asset.
Configuration file requirements for connection to local databases provides details about the
RAC_BACKUP_NODE_IP parameter.
In the
PowerProtect Data Manager UI, when you select
Infrastructure > Assets and then click the
Oracle tab, the
Name column on the
Assets page lists the Oracle application assets. Each asset name in that column is an Oracle database or instance name for a stand-alone system or a unique database name for a RAC system.
Use the following procedure to assign a preferred node for centralized backups of a selected Oracle database asset in the RAC environment.
Steps
In the
PowerProtect Data Manager UI, select
Infrastructure > Assets, and then click the
Oracle tab.
Select the required asset with the host type RAC by clicking the checkbox next to the asset name.
If you select more that one asset on the
Assets page, the option to assign a preferred node is disabled.
Select
More Actions > Assign Preferred Node.
In the
Assign Preferred Node for <asset_name> dialog box, select the preferred node from the list in the
Nodes field.
To change the
Nodes field value, select a different node name from the nodes list or click
Clear to delete the field value.
Click
Save in the
Assign Preferred Node for <asset_name> dialog box.
Results
After you assign the preferred RAC node by using this procedure, the node is used for backups of the selected asset during subsequent Oracle centralized backups.
