DYNCAT Commands
1 This scratches the volume that contains Version 3 of dataset OLD TRANS.
The volume serial number is unknown.
2 This deletes the version of 'SORTED AR' on volume 1766, and returns
1766 to SCRATCH status. If the 'SORTED AR' version contains multiple
volumes, all will be scratched.
3 This deletes Volume 1766 from the Catalog.
4 This deletes the dataset TEST FILE from the Catalog and returns all of the
tapes associated to the scratch pool.
5 This deletes externally owned volume 333333.
Note: The DELETE function, whether to delete an entire dataset, a volume
serial number, or a version of a dataset, is effective immediately.
DEQUEUE Command
Use the DEQUEUE command in a multi-CPU environment to release a Catalog
lock-out condition. This condition can occur if the DYNCAT program is canceled
while updating the Catalog.
The format of the command is shown next.
DEQUEUE
(no associated operands)
Example
An example follows:
// JOB UNLOCK THE CATALOG
// EXEC DYNCAT,SIZE=128K
DEQUEUE
/*
/&
The above job stream could be used to unlock the Catalog file.
Important! Before using the DEQUEUE function, ensure that no Catalog
update is actually in progress in any partition in any system. If the Catalog is
enqueued by a looping program, cancel the program before issuing the
DEQUEUE command.
