Monitoring process activity

To monitor process activity, you can display pending jobs. You can also enable applications to monitor activities of z/OS® UNIX processes.

While z/OS UNIX is being started or restarted, jobs are not processed. After the start or restart process has been completed, jobs will begin processing again. An operator message tells the system operator that jobs are waiting for z/OS UNIX to become available again.

The system operator can also use the D OMVS,A=DUBW command to show which jobs are in wait status. When the BPXO040I message is displayed in response, the PID field shows a ''-" instead of a PID value and the STATE field is set to D, indicating that the job is waiting to be dubbed. For example:
*10.52.00 STC00010 *BPXP022E ONE OR MORE JOBS ARE WAITING FOR UNIX SYSTEM  
 * SERVICES AVAILABILITY.
