The total number of active jobs is shown in the status bar at the bottom of the GUI window. Make
sure the include criteria specifies all jobs except system jobs to ensure that this number is
accurate. Select to include everything except System in the Type field. System jobs are not
considered when assigning a value to the active jobs at restart system value.
The Total Jobs (QTOTJOB) system value represents the minimum number of jobs for which
storage is allocated when you restart the system. The number of jobs is the number supported by
the system at any one time. This number includes the jobs on job queues, active jobs (including
system jobs), and jobs with output on output queues.
Additional storage is allocated when the QTOTJOB value is set so that the amount of
storagerequired exceeds the amount currently allocated. No action is taken when this value is set
so that the amount of storage required is less than the amount currently available. Set the
QTOTJOB value high enough so it is not normally exceeded by the total number of jobs.
In the GUI, right-click your system and select System Status to find the number of total jobs in
the system. Keep this number within reason because it is a factor in the time to perform a restart
and some internal searches. This can require periodic removal of jobs that have only job logs.
The CL Programming manual contains a discussion about the job logs and how to remove them
for jobs that complete normally. Knowledge of the job remains in the system and counts toward
the DSPSYSSTS value as long as a job has one or more spooled output files attached to the job.
Consider changing the Spooled File Action (QSPLFACN) system value to *DETACH such that
when a job ends, the spooled files are detached from the job and the job itself is removed from
the system.
Additional active jobs (QADLACTJ) and additional total jobs (QADLTOTJ) are two system values
that specify the additional number of active jobs and total jobs for which auxiliary storage is to be
allocated when the initial number of active jobs and total jobs at restart is reached.
QADLACTJ specifies the additional number of active jobs for which auxiliary storage is to be
allocated when the initial number of active jobs at restart is reached. An active job is one that has
started running but has not ended. This auxiliary storage is allocated whenever the number of
active jobs exceeds the storage which has already been allocated. .
QADLTOTJ specifies the additional number of jobs for which auxiliary storage is to be allocated
when the initial number of jobs at restart is reached. This auxiliary storage is allocated whenever
the number of jobs exceeds that for which storage has already been allocated.
