You can define vital record specifications to control the retention of data sets that might have been left open by a system failure or that might be open during DFSMSrmm inventory management. Using the OPEN or ABEND data set name masks in a vital record specification allows you to you define specific policies for these data sets so that they are not retained like normal data sets.

Specify the JOBNAME operand with the DFSMShsm and ABARS procedure names in the vital record specifications that you define to manage open data sets. This ensures that DFSMShsm and ABARS volumes are always retained permanently under DFSMSrmm until DFSMShsm releases them.

DSNAME('ABEND')

A reserved data set name mask to manage all data sets closed as a result of an abnormal end in a task.

DSNAME('OPEN')

A reserved data set name mask to manage all data sets open when inventory management vital record processing is run or open when the system failed.

JOBNAME(hsm_proc)

DFSMShsm procedure name.

JOBNAME(abars_proc)

ABARS procedure name.

COUNT(99999)

Specifies to retain all data sets forever or until DFSMShsm releases the volume by notifying DFSMSrmm through the EDGTVEXT installation exit.

CYCLES

Specifies that DFSMSrmm should retain data sets based on cycles or copies of a data set.
