You can manage scratch tape pools based on job names and data set names.

Recommendation: Use SMS ACS Storage Group assignment to manage scratch pooling with jobname and data set name for system-managed volumes. For information, see Making an ACS storage group assignment. For non-system-managed volumes, use the EDG_EXIT100 installation exit. See Using DFSMSrmm installation exits for information about using the EDG_EXIT100 installation exit.

Use the EDG_EXIT100 installation exit to select the correct scratch pool for non-specific requests for non-system-managed volumes and to decide whether the cartridge loader should be used. You can also use EDG_EXIT100 with criteria other than job names and data set names, but you must modify the supplied EDGUX100 exit module to do this.
