Doh!!!
stupid me :)
Ok Mandy, it is always better for perfomance to have your database spread
across muptiple PV.
I�ts more dificult perfomance tuning NT than Unix so you need to bee careful
in what decisions you make.
I have never seen this message beefore.
You should know that this problem you are talking about should be memmory
problem. You need to look carefully on your memmory recources. I think
SELFTUNESIZE uses no more than 25% of youre real phisical memmory any more
than that you have to tune youre self. Bee careful to not take memmory to
mutch memmory, that could have undesired affects.
Hope this helps.
Kvedja/Regards
