According to ADM315 :

"if processing time is more than twice of CPU time then there is a CPU bottlenecks...."cpu.png

in st03 i found attached screen shot.

so is there any CPU bottleneck in my system or any another way to check ?

Thanks

Hi,

May be or may not be. You need to drill down to the top two (others, WS-RFC) that are contributing to high processing time.

High Processing Time: Processing time directly affected by CPU. Actually processing time must not exceed twice of CPU time. If there is a bigger difference between processing and CPU times, there could be two options. First there could be a CPU bottleneck which makes work processes to wait for CPU; in this case a greater processing time will be caused by CPU wait time. Secondly if the work process stays in STOPPED status, processing time without CPU time will keep on counting, so again significant difference between process and CPU time will take place.

I would look into the NMON statistics to identify any CPU issues. You may get the NMON report and see the CPU utilization.
