JobWatcher is a tool that can show you wait states and times, and lots more. I think it is included with the system. Jim Oberholtzer mentioned it recently in these lists.

I have a complex SQL script that used to run in about 3 minutes and
processed through 700k records.

I made a bunch of changes and one of the changes has resulted in the run
time going out to 12 hours. I have all the advised indexes required by the
system.

I am trying to monitor system usage and found the following:

- CPU utilization is constantly around 40% (2 hours)

- Disk IO across all 10 drives is 1% or less (1 hours)

On the face of it, it appears the system is idle whilst it is processing the
data.

Does anyone have any advice on how to track this down. We are on V5r4 so no
IBM support?

Do you know how I can use the data base monitor to analyze what is going on?

Why can I not see where the processing is? It's almost like there is a wait
happening?

TIA
