DEALLOCATE Command
Function
The DEALLOCATE command removes a volume set from your job's list
of allocated resources. DEALLOCATE implies a DISMOUNT of the
specified resource. The logical name for the volume set is
cleared, and you will not be able to use that logical-name to
refer to the volume set.
Format
DEALLOCATE resource-name,resource-name...
Where: For disk volume sets, the resource-name is the volume
set-name or the structure name.
For tape volume sets, the resource-name is the logical
name.
DEALLOCATE has one switch:
/HELP Prints a short description of the command. If you
specify an argument with this switch, the argument will
be ignored.
Associated Commands
ALLOCATE Informs the system of your future need for a
resource.
MOUNT Requests ownership of a resource.
DISMOUNT Removes the resource from your job's search
list. Dismounts the volume set from the unit if
no other users are accessing the resource.
SHOW ALLOCATION Prints a list of the resources that are
allocated and mounted for your job.
SHOW QUEUE Prints a list of the jobs in the system queues.
Characteristics
Runs the QUEUE program.
Destroys your core image.
Requires LOGIN.
Example
The following example shows the use of the ALLOCATE, DEALLOCATE,
MOUNT, DISMOUNT, and SHOW ALLOCATION commands. The resources are
reserved for a multivolume tape volume set with the ALLOCATE
command. The name of the volume set is TAPE-SET, and it contains
three volumes. The logical name TS is assigned to the tape set.
The tape is write enabled, and it does not have standard labels.
.ALLOCATE TAPE-SET(VOL1,VOL2,VOL3):TS/WRITE-ENABLE/LABEL:NONE<RET>
[ALLOCATE REQUEST TS QUEUED, REQUESTS #672]
A file structure named DSKR: is mounted for the job:
.MOUNT DSKR:<RET>
[MOUNT REQUEST DSKR QUEUED, REQUEST #673]
[STRUCTURE DSKR MOUNTED]
The job's resources are shown using the SHOW ALLOCATION command:
.SHOW ALLOCATION<RET>
ALLOCATION FOR JOB 59 MARY MAROTTA [27,5434]

The tape set is mounted, and the resources are again displayed:
.MOUNT TS<RET>

TAPE-SET VOL2 MAGTAPE VOL. 1 0
TAPE-SET VOL3 MAGTAPE VOL. 1 0
After work is finished by accessing the tape set and the
structure, the structure is dismounted. Because the structure
was not explicitly allocated, it is automatically deallocated.
.DISMOUNT DSKR<RET>
[STRUCTURE DSKR DISMOUNTED]
The tape volume set is dismounted:
.DISMOUNT TS<RET>
[VOLUME SET TS DISMOUNTED]
The job's resources are displayed:
.SHOW ALLOCATION<RET>

At this point, the tape set can again be mounted, or it can be
deallocated. The tape set is deallocated:
.DEALLOCATE TS<RET>
[VOLUME SET TS HAS BEEN DEALLOCATED]
.SHOW ALLOCATION<RET>
