Ed,
The only way your going to do this is through Oracle Resource Manager.
You'll need an 8.1.x Enterprise database. Then you can setup your resource
plans and groups to manage who gets how much CPU at a time. Any of the
operating level tools out there cannot get down to the level of granularity your
asking for since all of the activity happens within Oracle. All those tools can
do is control the amount of CPU that Oracle gets which has a global effect that
hampers all users of the database.

Raj,
Thanks for your input.
>From what I understand with profiles,
the session will be terminated once a
threshold is reached.
In this particular case, I cannot
terminate the session. I need to be able
to control the CPU usage of a session, without
ending it.
If this cannot be done within Oracle, then
maybe it can be accomplished through the OS.
thanks.

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

Subject: controlling CPU usage through Oracle
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.
