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.

Third party tools would be nice, but not in the cards at the moment.

PEX is an extra cost program from IBM right? Also probably not in the cards at this point.

I've got 5722-PT1, Base, Manager, & Agent.

Just been a while since I've used them. Before jumping into the manual for them, do they have the
reports I need?

Last job I had, they had significantly oversized the box they purchased right before I got there. CPU
usage was less than 10% and often less than 5% all day long.
