We tried the automatic tuning, and ran into severe optimizer problems.  The
system re-optimizes stored procedures when changing memory pool sizes, which
causes much greater performance issues than to be slightly 'out of tune'.
Perhaps the fact that we have several hundred stored procedures makes it
unworkable in our environment.

Are we doing something wrong?  Is there a way to override the re-optimizing
when changing pool sizes?
