Release processing is done through the DSCL RELEASE action command. To select data sets to be processed. use the DSCL selection criteria.
The RELEASE command syntax is:
RELEASE PCTUSED=,PCTSECONDARY=,CONVERT
Specify the percent of used space that is desired in the data sets after processing. If no value is specified, all space in the data set is used. (Default is 100 percent.)
(Optional) Include this parameter to reset the amount of secondary space that is allocated for non-VSAM data sets selected for release of idle space. Specify a percentage (0-100) of the new primary allocation (after release of idle space) to be used to compute a new secondary space allocation.
This parameter causes non-VSAM data sets using less than one cylinder and allocated by cylinders, to have their allocations changed to tracks. (The secondary space allocation quantity is also appropriately converted; for example, one 3350 cylinder converts to 30 tracks.)
