CPU utilization Hitting 100% :

[Former Member]

Hello all,

In our Production system CPU utilization hitting close to 100% at certain hours:

Possible Suspects:

STO3N analysis shows that RBDAPP01 report is been used by several background jobs and it is consuming almost all work-process (on an average 28  wp of 34 ) on high CPU utlization hours

Also ALE ,RFC, SPOOL  consume a lot and have high response time.

We have many idocs with status 51 and 52 in BD87.

SP12 several objects with status inconsitency.

Could you please advice with a possible way to eliminate the problem : Many Thanks in Advance!!!

regards

alen

Hi Alen

we faced similar issue , and As RBDAPP01 Programs process IDOC ( SO,PO and Others ) those are very resources extensive . No. of Work Process used is reason for high CPU utilzation. There is two way to hadle this type of issue .

i) Increase Capacity : Adding Additional Server or add capacity( CPUs ) in Current Server . Increase the Work Process in Server .

ii) Change Parameters  : RFC server Group assigned in Batch Job (RBDAPP01 )  for parallel Processing have some parameter which decides like ( How many work Process used, % free WPs )  Reduce the no. of WPs used for such Jobs can reduce the CPU utilization and can be utilized for other Jobs, Processes . But it can increase runtime of RBDAPP01 job.

Thanks

Hi Alen,

From the SAP note

During the inbound processing of idocs through program RBDAPP01 the BDT objects were called to get the business partner relationship details .

When reading the relationship details due to the improper handling of read statement in OBJAP_CHECK routine causes duplicate entries in the internal table resulting in the performance issue.

It refers to a program correction which needs to be applied to resolve this issue.

Hope this helps.
