Look into Oracle Resource Manager.

You could use profiles to control CPU usage as well, more info is in
manuals.

Hi,
I'm looking for a way to control CPU usage of
particular queries on a database.
After exploring, and implementing ways of optimizing the code,
these queries can run anywhere from 45 seconds
to 2 minutes.
This database is 1 of 5 on this box. So, although it's important
to build effective queries, it's also important in this
environment that these queries do not impact the other
4 databases.
What I want to do is place a limit on CPU usage
without terminating the query. I've looked at profiles
with the "cpu_per_call" and "cpu_per_session" settings.
I have never used profiles, but from what I understand,
these will kill the session once they reach a threshold.
I'm also looking at database resource management.
This may be more appropriate for this situation.
Has anyone used this, and if so what are you
experiences ? Would you recommend it ?
Would the only way to control CPU usage on this
box, be through the operating system ?
I welcome any suggestions. I appreciate your time.
The environment is Oracle 8.1.7.2, AIX 4.3.3.
