Re: wrksysval QPFRADJ

Adjustment at IPL may be necessary if you add new hardware that requires a 
larger machine pool (more comm lines for example) - however, if you;r 
system has been tuning itself over time based on actual usage, then you 
IPL with QPFRADJ set to adjust at IPL, it will "undo" that tuning and use 
teh algorithm to calculate pool sizes and activity levels at IPL. 
I usually leave QPFRADJ at '3' - but change to '2' just before powering 
down the system if new hardware is going to be added (then change it back 
afterwards to '3').

Wow!  We just had a real eye-opener!

Some of you may recall that we've had some annoying performance problems
with one of our branch AS/400's over the past month.

On a whim, I finally checked QPFRADJ, and the dam*ed thing was set to
"1=Adjustment at IPL".  Seeing as we only IPL when absolutely necessary,
this setting doesn't help us a whole lot. 

I changed it to "2=Adjustment at IPL and automatic adjustment" and magic
happened!  Really smelling like a rose now!

I checked our other boxes, and they were all set to "3=Automatic
adjustment".  Is there any reason why, if you're already doing the
automatic adjustment, you wouldn't also choose to do the adjustment at
IPL?
