Once JES2 has been started, you can display the status of the JES2 subsystem using the MVS™ DISPLAY command. For a description of the DISPLAY command, see z/OS MVS System Commands, SA38-0666.

JES2 status information is also maintained by a JES2 monitor address space. The $JD STATUS command can be used to display any problems JES2 might be experiencing. The $D JES2 command can be used to display the current activity in the JES2 address space.
