An important function of monitoring job variables is to identify jobs in the commands for job management (see for the "Job/program monitoring").
In these commands, jobs can be addressed either via the TSN or via a MONJV (monitoring job variable).
Some of these commands (SHOW-JOB-STATUS, CHANGE-TASK-PRIORITY, CANCEL-JOB and FORCE-JOB-CANCEL) can be issued on a multiprocessor basis, i.e. they are effective across more than one computer.
Defining a monitoring job variable in a computer network is useful because the task sequence number (TSN) of a job is normally not unique in an MSCF network. Using a monitoring job variable that is unique network-wide can help identify a job wherever it is running in the MSCF network (see also the manual “HIPLEX MSCF” [8]).
In this case there is no change in the processing characteristics when entering the monitoring job variable. In particular, users cannot reference other users' jobs, even if they can access the others' monitoring job variable.
