Command Reference Guide

The -messages option removes session messages for all sessions older than
NumberOfDays.
The -daily option starts the same purge session as started every day at 12.00
(depending on the Application Recovery Manager global options file setting)
and is a part of Application Recovery Manager daily maintenance tasks. This
purge session deletes DCBF based on the catalog protection and removes obsolete
sessions and their messages, by running the omnidbutil -purge -sessions
KeepObsoleteSessions -messages KeepMessages -dcbf command,
where KeepObsoleteSessions and KeepMessages are specified in the
Application Recovery Manager global options file. Default values for these two
parameters are 30 and 0, respectively. The Application Recovery Manager
global options file resides in /etc/opt/omni/server/options on a UNIX
Cell Manager or in AppRM_home\config\server\options on the Windows
Cell Manager. The scheduled time for the -daily option to start every day is
defined by the DailyMaintenanceTime option in the Application Recovery
Manager global options file.
At least one of these options must be specified. You can change
DailyMaintenanceTime for the -daily option in the global options file.
-purge_stop
Use this option to stop a running file name purge session. This command only
sends a stop request to the Purge Session Manager. The response may not be
immediate.
-extendinfo
Displays information about existing extents.
-info
Displays information about the IDB.
-clear
Sets the status of all sessions that are actually not running but are marked In
Progress/Failed, to failed. It requires exclusive database access to ensure
that no session is running.
-change_cell_name [old_host]
This option changes the owner of the CDB to the current Cell Manager. It also
changes all references in the CMMDB from old_host to the current Cell
Manager. It modifies all media entries within the MMDB or CMMDB associated
with the original Cell Manager (old host).
If the old_host parameter is not specified, omnidbutil determines the previous
owner of the CDB (old host) from the database itself.
