Home -> Community -> Mailing Lists -> Oracle-L -> Re: Re[2]: controlling CPU usage through Oracle
Kevin,
Thanks for your input.
Just to clarify; I only want to control this
one database. I want to limit its resources
so it does not impact the other 4 databases on
the box. So, in that case would resource
manager be beneficial ?
Also, besides profiles, and resource manager,
does anyone know of any other tools provided
by Oracle which would limit resources ?
Or, any 3rd party tools that my be beneficial ?
I thank everyone for providing their input; it's much appreciated.
I don't think Resource Manager is going to do the trick here (I just read about it over the last week while preparing for OCP exam 4). Resource Manager would work great for a single database but Ed is trying to divvy up resources between 5 databases.
I don't have any good solution. I suppose if everything running on this one database was less important than anything on the other 4 databases, you could renice the one database. I think that would be ok provided all components of the one database were at the same nice level.

If you take RAC out of Oracle you get OLE! What can this mean?

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.
