ALTER CATALOG
ALTER CATALOG
The ALTER CATALOG command changes the configured attribute values of the
catalog process that affect the management of online and audit dumps.
RELEASED {OFF | ON}
determines the status of an online or audit dump tape volume after all the dumps
on it have been marked for deletion.
•
RELEASED OFF specifies that when all the dumps on a tape volume have
been marked for deletion, the status of the tape volume is changed to
SCRATCH. This status indicates that the tape can be reused for dumping and
that its contents are no longer available for file recovery.
•
RELEASED ON specifies that when all the dumps on a tape volume have been
marked for deletion, the status of the tape volume is changed to RELEASED.
This status indicates that the tape is not available for reuse in dumping or for
file recovery.
Dumps are marked for deletion according to the RETAINDEPTH option specified.
The originally assigned default is RELEASED OFF.
RETAINDEPTH integer
determines the number of online dump generations that remain in the catalog for
purposes of file recovery. Each generation is an instance of an online dump that
provides a point from which the file recovery can start; if three dumps were made
of the same set of files, the first dump would constitute the first generation, the
second dump would be the second generation, and so forth. The range for
integer is 1 through 99. The originally assigned default is 3.
ALTER CATALOG, attribute [,attribute]
where attribute is:
[RELEASED {OFF | ON}]
[RETAINDEPTH integer]
[RESET RETAINDEPTH ]
[ROUNDROBIN {OFF | ON}]
Note. For this and other optional parameters, the originally assigned default is the value
initially assigned to the parameter 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.
