Hi All,
In environment we are using 2818-X02 box with around 1100 MIPS and this boxes
is utilized by couple of LPARS(SYSP & SYST). One is a PROD and other is Play
LPAR and almost 90% of weight is contributed to PROD SYSP system.
We have a scenario of High CPU utilized only during our batch window(4hours)
and few days back the system was recycled due to the high CPU utilized and we
feel that this may create impact during Peak season in November, December.
Also we got a report from our batch team and most of batch jobs are using more
CPU time with very high elapsed time and below is for your ref.
JOB NAME CPU TIME ELAPSED TIME
Job A 29:22.1 01.48.26.24
Job B 19:12.3 02.44.26.24
We are position to bring down the CPU Utilization time and make the system
healthy and we are trying to split the Batch jobs and run on different time.
I would like to get some clarity on the Elapsed time, whether this elapsed will
make use of the CPU and will it be the cause of high CPU utilized during batch
window? Kindly clear me.
We value your valuable inputs and that would be helpful and please suggest is
there any other way to rectify this issue.
Thanks,
Vinoth M
