Hi Deepak,
Thanks for your help.
We didn't found SAP response time and certain operation become slow.
Just found the DB CPU utilizaion is between 69% to 99.9%.
Can't identified particular process which occupying very high CPU resorese.
I send an incident to sap and told me to make some tunings as below:
-------------------------------------------------------------------------------
please make some change to the parameter settings:
PARAMETER NAME WHAT YOU NEED TO DO
_ktb_debug_flags add with value "8"
_fix_control (7168184) add with value "7168184:OFF"
_fix_control (6120483) add with value "6120483:OFF"
_securefiles_concurrency_estimate add with value "50"
optimizer_index_caching delete
Then please monitor if the CPU usage is still very high.
---------------------------------------------------------------------------------
Do you think the solutoin above can work?
You're right. I do really need deep analysis and fine tuning.
I'll try my best.
I uploaded two attachment.
