If you use an Oracle Data Guard configuration that has the primary databases and the standby databases in different data centers, then you must configure a region-based storage plan or use the following procedure to configure the storage policies on each client so that the software uses the local MediaAgent after a failover. Ensure that the configuration covers all the primary and standby regions.
Procedure
-
From the CommCell Browser, expand Client Computers > client.
-
Right-click the agent, and then click Properties.
The agent properties dialog box appears.
-
On the General tab, do the following:
-
From the Data Storage Policy list, select the data storage policy that the software uses for data backups when a failover occurs.
-
From the Log Storage Policy list, select the storage policy that the software uses for log backups when a failover occurs.
-
-
Click OK.
