ALTER DATAVOLS
ALTER DATAVOLS
The ALTER DATAVOLS command changes the configured attribute values of a data
volume.
volume
identifies the data volume whose attributes are to be altered.
RECOVERYMODE {ONLINE | ARCHIVE}
determines whether audit-trail files associated with the data volume are held on
disk until they are no longer required for volume recovery.
ONLINE retains sufficient audit-trail files on disk so that volume recovery does not
need to restore audit records from an archived audit dump. Retaining audit-trail
files on disk, however, can affect audit trail management and transaction
processing. As an example, if this retention causes an audit trail to exceed a
capacity threshold before the TMP is allowed to purge the audit-trail file,
transaction processing is disabled.
ARCHIVE releases audit-trail files so that they are not retained on disk solely for
volume recovery; therefore, if volume recovery becomes necessary, one or more
audit dumps might need to be restored. You can only select ARCHIVE mode if
audit dumping is configured for the associated audit trail.
The originally assigned default is ONLINE.
Security Restrictions
You can issue the ALTER DATAVOLS command only if you are a member of the super
user group.
ALTER DATAVOL[S] {volume }
{(volume [,volume]...)}
[,RECOVERYMODE {ONLINE | ARCHIVE}]
Note. TMF is shipped from the factory with the $DSMSCM disk volume configured as a
TMF data volume. Although you are free to add other TMF data volumes to the
configuration, you should not remove $DSMSCM as a TMF data volume. See also the
note about the preconfiguration of active-audit volumes that appears under the discussion
of the ALTER AUDITTRAIL
command.
Note. For this optional parameter, the originally assigned default is the value initially
assigned by TMF. The originally assigned default is used for the parameter when no one
has explicitly specified or altered this parameter’s value in a previous command. For more
information about how defaults are assigned, see Usage Guidelines
