The priority in the user profile is the maximum scheduling priority, not
the run priority. The scheduling priority determines the order in which
jobs are taken off the job queue.

The run priority, along with the time slice, is set in the class
description which is selected by the routing step in the sub system
description. Most interactive jobs are by default running at 20, but the
console is generally at 10 (so it can preempt runaway jobs), and batch jobs
are usually at 50. Timeslice can affect job performance as well since it
affects how long a process can run before it has to give up the processor.
Interactive jobs generally come in at 2000 while batch jobs get a much
longer timeslice at 5000. This can make batch jobs run faster than
interactive jobs even though they have to wait for all the interactive jobs
to give up the processor before they can grab it.

Hi, Normally if not adjusted the ODBC jobs run at prio 20. You can
change the class-object to prioritize down to 50 or similar.
Put a line in your startup program to set the prio ar evert IPL.

Interactive priority is set in the user profile and usually 3. That's way
more than 20, so reducing to 50 would not really help with my issue. AFAIR,
priorities are not an absolute setting but a relative-to-each-other
parameter. The machine isn't doing much when not processing bulk ODBC
inserts, so it's even not other jobs slowing down the interactive job.
