Performing DB2 HADR Restores

You can perform an out-of-place restore for DB2 HADR scenarios.

Note: The destination target database path (Restore Options dialog box, General tab, Target Database path) and the destination storage path (Advanced Restore Options dialog box, Storage Path tab, Paths) must match the values that you used on the source.

Before You Begin

  • Configure the standby database to be in roll-forward pending state.

    On the standby database, edit the /etc/CommVaultRegistry/Galaxy/Instance001/Db2Agent/.properties file and add the following line, substituting the Db2_instance_name parameter with the standby instance name and the STANDBY_DB_NAME parameter with the standby database name.

    Note: The Db2_instance_name parameter must be in lower case and the STANDBY_DB_NAME parameter must be in upper case.

     
    <Db2_instance_name>_<STANDBY_DB_NAME>_sDb2RFPendingReqd Y
