Updating the DFSMShsm control data sets

You can use the UPDTCDS command to update specific fields within the control data sets. Specifically, you can update the expiration date of copy pool dump copies. DFSMShsm updates all of the corresponding control data set records with the value specified on the UPDTCDS command.

To display the current versions, dump classes and expiration dates for existing dump copies associated with a copy pool, use the LIST COPYPOOL(cpname) command. You can then use this information to issue the UPDTCDS command to update an expiration date for a dump copy.
