Number of jobs generated

The following BMCTRIG options determine the number of jobs generated:

  • NUMJOBS or MINJOBS is the number of jobs to generate.
  • MAXOBJECTS is the maximum number of objects per job.
  • MAXSTEPS is the maximum number of steps per job (not available in the exit).
Warning

Note

Specify the lowest MAXOBJECTS value feasible, especially if you intend to use parallel processing. Workload balancing uses the exit only to obtain the job card but not to determine whether to issue a new job command.

BMC recommends using syntax to control job options and using an exit only for job cards.

The sample user exit generates new jobs, at least until the MINJOBS value is reached. If the user exit generates enough jobs to process all objects with exceptions before reaching the NUMJOBS value, null IEFBR14 jobs are generated for the remaining jobs. For example, if you specify NUMJOBS=4 and the first three jobs include all selected objects, a fourth job is still generated. The fourth job contains only an IEFBR14 step.

If you are not doing workload balancing and BMCTRIG finds more exceptions than the specified minimum number of jobs can contain, it continues to produce jobs until all objects with exceptions have been placed in jobs. If you are performing workload balancing, after BMCTRIG generates the number of jobs, BMCTRIG does not add work, and exceptions remain active.
