RE: controlling CPU usage through Oracle

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.
