To control the JES2 health monitor and request data it has recorded, you can issue appropriate JES2 $J commands. (The dollar sign ($), is your specific command prefix as assigned by the CONCHAR= parameter on the CONDEF statement and changeable as appropriate for your instance of JES2.) However, the J is unique to this set of commands and distinguishes them so they receive special JES2 processing. These commands are routed immediately to the monitor command subtask, and except for SAF Exits 36 and 37, bypass exit processing, including Exit 5, the command pre-processor routine. This can cause $J commands to be processed out of order from other JES2 commands issued by the same source.
