Can these tasks go on JOBQ?
Can they be given a lower priority than other tasks?
Can they go into their own sub-system which sets aside what resources they are to use up?

We use more than one JOBQ, with one reserved for long running jobs. Managing which end up on which JOBQ is a pain in the rear end.

On our 810 V5R2M0, we're having some problems with queries consuming a
lot of CPU, and slowing down all other tasks.



These queries originate mainly from 2 sources :

1.      Programs with embedded SQL, which produce statistics over a
specified period of time
2.      An SQL-tool, running on a PC-client, which does inquiries on the
AS400 database through ODBC.



The fact now is, that when a user starts a query (which he can define
himself) the system becomes very slow and the query consumes a lot of
CPU, killing all other jobs.



My question is : is there a way to prevent these tasks from putting the
AS400 to his knees.  I still want these tasks to be executed, eventually
at a slower rate.  But the essential is that the other jobs should not
suffer under this query.



Can anyone point me in the right direction ?
