JES3, a z/OS MVS subsystem, manages resources and work flow before and after jobs are processed. You can enable JES3 to allocate TS1130 (3592 Model E06) tape drives and tape volumes in an SMS-managed IBM tape library environment (automated or manual) for 3590 Model B emulation only. To do so, you need to specify at least one of these library device group (LDG) names in your JES3plex. An LDG is a predefined set of tape subsystems within a JES3plex.
