Subject: Re: Cache Hit % dropping on NT
What platform are you running on you�re server. Is there any other
applications on your server witch could be pulling resorurces.
If you are using AIX, then is the database on one pv or spread across
multiple.Where on the pv is the lv witch you are keeping youre database, it
does matter when perfomance tuning, although i don�t think it would matter
to the SELFTUNESIZE.
