Home -> Community -> Mailing Lists -> Oracle-L -> RE: High % sys after Installing Solaris 8 on APP Server
E10K Specific Patches + Generic Solaris 8 Patches have been applied by the Sys Admin /etc/system parameters have Also been Changed NOW
Unfortunately I am NOT much acquainted with Sys Administration , So if you have Any Specific Pach Numbers OR /etc/system parameters please tell them Explicitly
Also the DB & APP Servers have been interchanged i.e. Application S/w moved to the machine which was previously Containing the Database & vice-versa to see if it is a machine specific Issue & whether HIGH % sys Utilization Occurs after interchange too .
This was done Because % sys Utilization on DB Server machine was observed to be LOW (10 to 15 %) when the same was High (50 to 90 %) on APP Server
Under Load We have yet to see How the %sys will be after moving the Application to the machine which was previously Containing the Database
NOTE - DB Server is also an E10K machine like APP Server
Thanks

Hi Vivek,
i am not an Oracle expert but check with Sun for Solaris 8 release
compatibilty with the Starfire(E10K)
as some of the older E10K's sold with Solaris 2.6 were never tested for
Solaris 8 performance and i suspect
your E10K is one of that lot of Starfire's sold.i may be wrong but still
check it out as it may help you isolate the cause.
Please also do check your /etc/system shared memory and semaphore parameters too.
Regards,
Amit
