Since batch jobs are typically low priority jobs that require a special system environment in which to run (such as running at night) they are placed in batch job queues. In the job queue the batch job receives a run time schedule and a priority. To submit a job to a batch job queue, you use the character-based interface and one of two commands.
Command: Submit Database Job (SBMDBJOB)
The difference in these commands is the source of the job:
SBMJOB JOBD(QBATCH) JOB(WSYS) JOBQ(QBATCH) CMD(WRKSYSSTS)
