UNCATALOG


>>-+-----------+-----------------------------------------------><
   '-UNCATalog-'

UNCATALOG applies to physical and logical data set dump operations.

For a physical data set dump operation, UNCATALOG instructs DFSMSdss to uncatalog any single-volume, non-VSAM, cataloged data sets successfully dumped from the current volume.

For a logical data set dump operation, UNCATALOG instructs DFSMSdss to uncatalog any successfully dumped single or multivolume non-VSAM data sets that are currently cataloged. (For VSAM or SMS-managed data sets, use the DELETE keyword.)

Note:

UNCATALOG is ignored for VSAM and SMS-managed data sets.
Do not specify UNCATALOG with CONCURRENT, because after the concurrent copy operation has begun, the original data can still be updated.
For a logical data set dump operation, the use of the UNCATALOG keyword causes the enqueue in a data set to be held until all data sets are dumped. DFSMSdss does not uncatalog the data set until after all data sets are dumped.
Any non-SMS, non-VSAM data set that has a high-level qualifier of SYS1 cannot be uncataloged unless PROCESS(SYS1) is specified.

For information about a patch to modify the UNCATALOG algorithm, see Using RESET or UNCATALOG in a logical data set dump (PN60114).
