WORK WITH MONITOR STATUS
The Work with Active Jobs display shows the performance and status information for jobs that are currently active on the system. All information is gathered on a job basis. The jobs are ordered on the basis of the subsystem in which they are running. Jobs that run in a subsystem (autostart jobs, interactive jobs, batch jobs, readers and writer) are alphabetized by job name and indented under the subsystem monitor field they are associated with. Subsystem monitors (with the jobs in the subsystem grouped under each monitor job) are alphabetized and presented before system (SYS) jobs. The system jobs (SCPF, QSYSARB, QLUS) are alphabetized by job name and presented following the subsystem monitors and jobs within the subsystems.
It is possible for a job to not appear on the WRKACTJOB display even though an active status is shown for the job on one of the following displays:
•Work with Job (WRKJOB)
•Work with Subsystem Job (WRKSBSJOB)
•Work with Submitted Jobs (WRKSBMJOB)
•Work with User Jobs (WRKUSRJOB)
This is because a status indicator that is used to determine whether a job is active in the job’s internal structure indicates an active status just before and just after the actual processing of the job. Normally, the amount of time that a job is in this state is very short, but the following conditions can make it longer:
•If there are many jobs in the system competing for processor use, each job has a smaller share of processor time, which can increase the amount of time a job is in this state.
•The machine does not start the process for the job until an activity level is available for the job being started. If the activity level has already been reached, the job remains in this state until an activity level is available.
