JSTAT <jobname>

JSTAT is useful for monitoring the status and activity of another job. It displays a dynamically updated screen full of information such as the number of reads, writes and basic instructions, both total and rate/sec over the last sampling interval. It also shows the last basic instruction, last xcall, last line number, current PPN, program, job status flags, etc. This can be useful in a variety of circumstances, such as debugging a job that appears to be in an infinite loop, or determining whether operator is actively keypunching or a remote job is safe to kill.

As with other utilities that rely on inter-job communication, such as KILL, FORCE and SEND, there are privilege issues to consider under UNIX/Linux, whereas under Windows the main issue is the IJCFREQ setting in the miame.ini. Refer to File Ownership and Privileges for more information on the privilege issue.
