Actual execution time of the job

Post by pawan.konduru » Tue Oct 07, 2014 1:56 am

Hi,

can any one tell me how to get the actual execution time of a job.

as per my understanding the execution time will be depend on the CPU utilization, so how to know actual time if the CPU utilization is 100%.

For ex. below are the stats for the job
STARTED - TIME=16.04.34
ENDED - TIME=16.08.36
TOTAL CPU TIME= 96.14.
TOTAL ELAPSED TIME= 242.30

------ JES2 JOB STATISTICS ------
06 OCT 2014 JOB EXECUTION DATE
222 CARDS READ
1,114 SYSOUT PRINT RECORDS
0 SYSOUT PUNCH RECORDS
87 SYSOUT SPOOL KBYTES
4.04 MINUTES EXECUTION TIME

Thanks in advance.

If your JOB elapsed for 242.30 seconds and only use 96.14 seconds of CPU, then it wasn't at 100% throughout the JOB.

Can you explain a little more what you mean, perhaps with reference to the figures you have shown?

Actual execution time of the job

My requirment is, in my project some of the processes are converting into Informatica.

so i want to compare the execution time in mainframe vs informatic.

here in mainframe whenever i submit the job the Total CPU Time is varying which is depending on the CPU avaliability, so how to know the actual execution time of the JOB. sothat i can compare with the Execution time in Informatica.

Well, the CPU time is the time the JOB/step would take at 100% CPU.

To find out how long something runs "on average" (elapsed time) you're going to have to collect some figures and work it out. Your "Production Control" people may have something to aid you there.

If you try to compare it to another system, "how long should it take" you have a very tricky task. You either go Informatica running it, within acceptable times on that system, or you don't, if the timings are unacceptable.
