    how to limit oracle to use only 2 out of the 4 CPUs

    Hi,

    How would it be possible to limit an Oracle instance to use only 2 out of 4 CPUs.

    Would it work by using DBMS_RESOURCE_MANAGER and set CPU_P1 => 50 ?

    Thanks for any feedback

    no resource manager wont do it, that just assigns 50% of the available cpu which oracle has to the session. It is only used when there is resource contention.

    would it help to reduce the parameter CPU_COUNT to 2 ?
