CPU idle time is very low in pick hours

Dear Freinds,

When I check into the st06 during our pic hours the idle time is very low.

Even I checked the top 40 CPU processes, the users are as below

<sid>adm

ora<sid>

ora<sid>

ora<sid>

<sid>adm

daaadm

<sid>adm

root

<sid>adm

orapnc

sapadm

root

root

ora<sid>

ora<sid>

root

root

root

Can anyone tell how to analyze further to increase the CPU idle time of the system.

Regards,

Hi,

Also take into mind that st06 depends on saposcol/saphostexec data.

It may be worth it to at in the peak times have a look at O/S level as well i.e. task manager in windows and/or top in unix/linux environment to see if the results you see are accurate.

Idle time in peak times would be a blessing but also could mean if this information is accurate perhaps you can re-assign them somewhere assuming it is possible on your servers.

Kind Regards,

Hello Sonal,

The purpose of the CPU is to be used .

So, if you see a low CPU idle time during peak hours, I would not say that this is a problem itself.

Is this causing performance issues in the system? For example, the users are experiencing slowness during peak hours, and when performing the same task at non-peak hours it is faster.

If there is indeed a performance issue, you can consider to:

  • add more CPUs;
  • move the database or the SAP instance to a different server, using one server exclusively for the database system and other server exclusively for the SAP instance. This way, both systems (DB and SAP) would not "compete with each other" for CPU time.
