RE: Slow AS400 performance

["Sellers, Eric" <Eric.Sellers@xxxxxxxxxxxx>]

Mike,
MPG Inc. makes a great tool for looking at most aspects of iSeries
performance. I have seen their product in action. I would be more than
glad to tell you my experience with it and put you in touch with them or
a partner that can help you use the tool.

Subject: Slow AS400 performance


I am getting vague complaints from our users/developers that one of our
AS400's (a 270, v5r3) is "running slow". I don't think it's a CPU
problem, more like IO is getting thrashed. 
One Developer suggested that it may be QYIVRIPS. I did notice the
message "Attempt to download a current phone list was unsuccessful." in
it's job log, but I'm not too excited over that. 

What tools/methods are there for determining who/what is thrashing the
IO on the machine? 
I'd rather start this way rather than calling IBM, telling the vaguely
"our machine is running slow", and then imagining the IBM Tech's eye's
rolling back in his head upon hearing the question.
