The data set must be cataloged, and it must be a partitioned data set.
The MINIMUM and PDS parameters are always used together and are never used with other Basic Scheduling parameters.
The PDS parameter identifies a library. The MINIMUM parameter specifies the minimum number of free tracks required by that library.
These parameters are intended for use (that is, definition) in jobs or started tasks that compress, clean and/or enlarge libraries, or which issue a warning message to the IOA Log file, that is, if the TASKTYPE parameter is set to WRN.
If the MINIMUM and PDS parameters are defined for a job, the scheduling of the job is not related to or dependent upon any date criteria. Instead, the job is scheduled if the actual number of free tracks available in the specified library is below the specified minimum when the New Day procedure is run. The job or started task can then compress, clean, or enlarge the library, or issue the appropriate warning.
Note: The PDS parameter does not work with PDSE-type libraries because they always appear to be 100 percent full.
