Re: job accounting or what?

I saw a demo of a performance tools suite called iDoctor from IBM. 

http://www-912.ibm.com/i_dir/IDoctor.nsf

In the demo they watched a job realtime and could tell exactly where it was
spending its time, waiting for CPU, using CPU, object lock, I/O, if it was
waiting on a file/object they could drill down and see what object. It
looked like an awesome tool, and they offered a free trial. Unfortunately I
installed the free trial, then had to go fight other more urgent fires, and
never got my system showing the cool stuff I saw in the demo, so I can't
really give you a personal testimonial of how much it helped us, but it
looked like a potentially wonderful tool.

Hi,

Job accounting could give you some starting values like CPU time used and 
database
activities (number of reads, writes and so on). This could already point 
you in the
right direction -> perhaps excessive reads or writes?
