A venerable STC started getting 0470 ("user unauthorized for subsystem") when
trying to allocate an INTRDR after we
added a lot of new function in a separate subtask. Disabling the new subtask
allowed the allocation to work as before.
Searching I found OA50565 which describes the same thing happening to IDCAMS.
The problem was the new
subtask was calling IKJTSOEV and that causes the PSCBJCL flag to be turned off
so the task cannot submit jobs. The apar
states that IDCAMS now establishes a TSF with the PSCBJCL on without saying
how. I tried forcing the PSCBJCL flag on after
the call to IKJTSOEV but that resulted in an LE exception when I tried the
allocation in the other task. Toggling the flag in the
task that does the allocation seems to work OK so far: I set the flag on,
allocate the INTRDR, turn it off and nobody seems to
notice.
I am not too happy with this arrangement! Does someone know how to establish
the TSF with the PSCBJCL flag on as in IDCAMS, or equally good, how to cancel
the TSF once it is established. I could find no function call that does that.
Thanks
Robin
