Tomek,

You can have multiple job queues in SUBSYSTEM QBATCH.  Each job queue can
have multiple priorities, and each priority can have a maximum number of
jobs running that can run a the same time.

To see this do a WRKSBSD QBATCH and then take the option to show job queue
entries (option 6 on V5R4) This will show you what the maximum number of
jobs is for each priority and jobq.  As Rob said, you can control what jobq
and prioriy a job runs through by the job description.

For the user that needs the high priority regardless of what they are
running, they could get their own JOB QUEUE.  I have done that for a lot of
years for programmers, not because they need high prority, but because they
can have compiles or test runs that can clog the system.

Remember that there are three max active numbers - SUBSYSTEM,  JOB QUEUE or
PRIORITY within the JOB QUEUE. If you set the maximum number of jobs in your
QBATCH subsystem to 10, and allow only one or two long running report jobs
at a time, it will leave 8 slots for higher priority jobs to run.  If you
use 3 of those slots for print jobs, you have 5 left for the really high
priority jobs.  Of course you must tune this to what your system resources
can handle.
