Avoid A and B queues for your programs/jobs - those are reserved for
system processes.
Generally use the C queue for sessions and D queue for jobs, although
some 3rd party products that run via background jobs need up-lifting to
CQ. We also run some of our own "important" background jobs in the C
queue.
I've not often seen the E queue being used except for un-important jobs
that have no possiblity of impeding (e.g. tranasction locks) other
processes.

Subject: [HP3000-L] SHOWQ command and Quantum question
Greetings to all you Listers out there!
I want to pick at some of those massive brains out there with some MPE
wizardry.
I was wondering about how others have their systems setup with regard to
running jobs in different queues.
If I issue a "showq;active":
I get a table like this:
DORMANT RUNNING
Q PIN JOBNUM Q PIN JOBNUM
B U2603 #J3459
C M993 #S6417
C U1833 #J3917
D U3000 #J3941
------QUANTUM-------
QUEUE BASE LIMIT MIN MAX ACTUAL BOOST TIMESLICE
----- ---- ----- --- --- ------ ----- ---------
CQ 152 200 1 2000 2 DECAY 200
DQ 202 238 2000 2000 2000 DECAY 200
EQ 240 253 2000 2000 2000 DECAY 200
I guess I need some more information about how this mechanism works.
It seems to me that the CQ gets all the available QUANTUM allocated to
it, yet is currently using 2.
I guess I'm wondering if this should be a little more "balanced" and is
there a way to change this situation or is it even necessary?
I know that since we migrated to UC4 (on MPE) most of the production
jobs that
UC4 processes run at a DQ.
We only have some higher priority jobs running all the time at CQ and 1
or 2 of our realtime jobs run at BQ.
Thanks,
Bruno
