Dear Friends,
From the job log I will be able to take CPU time and Elapsed time.
Would any body tell me how to take the I/O count from joblog?
Thanks in advance for your reply

Look at EXCPs (Execute Channel Program). _________________ All the best,

Your site must use an SMF exit routine to write the end-of-step stats (such as EXCP count) to the JOBLOG. This is not a default action. Search for IEFACTRT. _________________ Regards,

Thanks papadi & Bill Dennis.
Just to confirm, let me ask again..
In our job log, I could see following lines,
-STEPNAME PROCSTEP RC EXCP CONN TCB SRB CLOCK SERV WORKLOAD PAGE SWAP VIO SWAPS.
So Papadi, you mean to say the number that appears under EXCP is the I/O count of that particular step. If I need the total I/O of the job then I need to sum the I/O count of all the steps in that job. Am I right?
Thanks

Am I right? | Basically, yes. Keep in mind that 1 excp does not always equal 1 i/o, but the numbers are quite close. Also, keep in mind that the count is physical records (blocks) rather than logical records (what a program reads). _________________ All the best,
