Re: How to identify a runaway job

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Others have suggested WRKSYSACT.  You don't mention which OS level your 
running.  At V6 and above WRKSYSACT is part of the OS, at V5R4 it's part 
of the Performance tools.

Try just plain old WRKACTJOB and use F11 once to bring up elapsed 
numbers.  Put the cursor on the column labeled AuxIO and press F16 to 
sort.  The highest I/O job will pop to the top.  Chances are strong you 
just found your problem job.

Commercial products however good they are won't help when the system is 
nearly in a critical state.
