$JSTOP - Terminate monitor address space

Function

To terminate the JES2 monitor address space. You might need to stop the monitor address space because it is not functioning properly or you want to reset the time frame for the statistics the monitor has been maintaining.

If the JES2 address space is functioning, it restarts the monitor address space within 32 seconds of discovering it has terminated, or when you hot start JES2, JES2 determines if the monitor also needs to be restarted. This is either a normal termination ($JSTOP) or an abnormal termination (ABEND or CANCEL command).

Authority Required

This command requires display authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS™ system command group is assigned.

This command requires read security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide.

Processing considerations

The following restrictions apply to all monitor commands. They:
  • Can only be issued through the MVS command interface (consoles or MGCRE) or JES2 automatic commands.
  • Cannot be issued from the JES2 initialization data set, NJE/RJE, $M commands, or through a reader (INTRDR).
  • Can be the object of a $VS command.
  • Are not limited by CONDEF CMDNUM=.
  • Are not limited by CONDEF DISPMAX=.
  • Support L= for directing the output but do not honor CONDEF RDIRAREA= or REDIRECT= parameters.
  • Cannot use the JES2 command separator, semicolon (;), to separate monitor commands unless it is also the MVS command separator.
  • Starting in z/OS V2R3, the monitor address space no longer clears the history entries when it goes down.

Scope

Single Member. The command affects this member only.
