In MVS™, you can use the System Display and Search Facility (SDSF) to monitor and control a job. You can also use the TSO/E CANCEL, STATUS, and OUTPUT commands.

In the shell, you use the ps command or the jobs command to check the status of a job, and the kill command to end a job before it completes.

Additionally, in the shell you can stop, or suspend, a foreground job, and then enter the bg command to run it in the background or the fg command to start it back up in the foreground.
