RE: Quantify processing wasted by lots of little jobs

PEX is not extra cost. You don't need anything extra to run PEX 
traces - it's part of the OS. Now IIRC, Performance Tools might have 
some reports. But I think a better tool is a thing called PTDV. Go to 
www.iseries.ibm.com/perfmgmt and take the link there to PTDV 
(Performance Trace Data Visualizer). It's free. There are also Job 
Watcher and iDoctor there, and you CAN get a 45-day trial, IIRC. But 
PTDV might give you all you need.


Of course, there is no reason not to run your own queries over the 
PEX output files - there's a bunch, and there is documentation on 
which ones might be useful. Of course, the developers of PTDV have 
already done the heavy lifting.
