Database and backup server time synchronization
The database server time and backup server time should be set to the present time, or the task status
related to replica management operation is not updated correctly. If the time zone of the database
server and backup server is changed, from the Explorer menu, choose Administration and then
Information Source. Choose the relevant server, and then click Refresh Agent to update the information.
Deleting copy groups used for replica operations
When an attempt is made to delete a copy group that is in a HORCM instance used by Application
Agent, the Pair Configuration Wizard task may fail with the error message KAVN02521-E
(RPM-00527). If this occurs, first delete the HORCM instances from the Setup Application Agent dialog
box on the database server and the backup server.
Exchange Server offline address book data
Application Agent cannot treat Exchange Server offline address book data as a backup or restore
target. As a result, do not put data files, transaction log files, or checkpoint files that are backup
targets in the volume that is storing the offline address book data. If the backup target files are stored
in the same volume that is storing the offline address book data, you must backup and restore the
offline address book data separately.
Changing a backup server
When changing a backup server using the database server Application Agent settings, first delete
any existing replica tasks, change the backup server, and then recreate the replica tasks. If any replica
tasks remain from before the backup server is changed, those tasks might be executed for the old
backup server.
Simultaneous operations
Host-refresh operations, replica-mounting operations, and replica-unmounting operations all take
longer than usual if they are performed while a replica-creation or replica-restoration task is being
executed. To avoid this, use the Task List to ensure no replicas are being created or restored for any
hosts where you plan to perform such operations.
Task scheduling
When a schedule is set from the Create Replica Wizard or the Task List, the window may not display
a response when Monthly is selected for the schedule type and one of the following dates is selected:
• 31, when the system date is April 1, June 1, September, 1 or November 1
• 30 or 31, when the system date is February 1 on a leap year
• 29, 30, or 31, when the system date is February 1 on a non-leap year
To recover from this condition, follow this procedure:
1. On the database server, start the Windows Task Scheduler.
2. In the Processes tab, select the process whose name in the Image Name column is drmjobsch.exe.
3. Click End Process.
If the recovery procedure above is not performed, the next time an attempt is made to create or edit
a replica task, the RPM-24103 message might be output and the operation may fail.
