RE: Database using 100% of CPU

It sounds like you may need more ram.

I've looked at the server. Total Commit Charge is 574968. Total Physical Memory is 523680. I can see that it's over, but what am I looking at? I understand physical memory, but the help on 'Commit Memory' in windows is less than helpful.

Do I need to reboot the box?

Thanx,
Mike

How much memory is being used, vs. available physical RAM?

Check Task Manager | Performance tab, compare Commit Charge Total (LL
corner) vs. Physical Memory Total (UR corner).

You should stay below physical RAM as much as possible, because Oracle
really does not like NT virtual memory.

        Steven:

        I also have this happen on one of our smaller DBs running NT.  I
haven't
        found a cause yet either.  Rebooting seems (so far) to be the only
cure.
        If you get any replies would you please summarize to the list?

        Thanx,
        Mike

        We are having a problem with our database - it is using 100% of the
CPU.
        This has only started happening recently, and restarting the
database
        temporarily
        stops it happening - it usually recurrs a few hours later.
        There are no jobs running, and at the moment there are no active
        connections.
        Obviously something has kicked this off, can anyone shed any light
on this
        or
        suggest how to find out what is running on the db?


        Thanks in advance,

        Steven H.
