this was to determine how many CPU's you would need to license for the

Hi,
I am trying to configure PAV on RHEL 4 and am running into a problem. I
have been working from the "How to Improve Performance with PAV November
17, 2006" document.
So it appears PAV is configured.

Here are my results and this is the case before and after the change to
multipath.conf per the bugz workaround.

Actually, I think I know how to do that:

So is it your impression that PCS variables and IBM variables are

If you are using standard Oracle tools for checking I/O response

When we ran on aix/sun and compared to zVM and Linux on z-Series, we
found the numbers to be very much the same. The only thing that the
Oracle tools cannot do is the
