Using RESET or UNCATALOG in a logical data set dump (PN60114)

For a logical data set dump operation, use of the RESET or UNCATALOG keyword causes the enqueue on a data set to be held until all data sets are dumped. DFSMSdss does not reset the data-set-changed indicator or uncatalog the data set until after all data sets are dumped.

This function is affected by setting the flag at offset X'1E' in ADRPATCH. The settings are listed below:

X'00': DFSMSdss functions normally as described above.
Any setting other than X'00': DFSMSdss resets the data-set-changed indicator or uncatalog the data set when the data set is dumped. The enqueue on a data set is released after DFSMSdss has completed resetting the data-set-changed indicator or uncataloging the data set.

To set the flag to on dynamically, use the SET PATCH command. To set the flag to on permanently, modify the sample JCL (see Sample JCL) as follows:

//SYSIN DD *
   NAME ADRDSSU ADRPATCH
   VER   1E        00
   REP   1E        FF
