Performance on Oracle 10g x64 and ECC5.0 (640 x64) on Windows 2003 R2 x64

Hello all,

We have a serious problem with this landscape. SAP kernel updated to 155. Oracle updated with OPatch to patch 12 (latest) and the new database statistics were updated. It seems an IO degradation because the Average Disk Queue is very high. We tested the hardware and it performs very well compared to other solutions. In the mean time we talked to the support from SAP and they didn't find any problems on configuration of parameters and recomended to turn off AUTO_SPACE_ADVISOR_JOB in Oracle, but the performance is still low. Does anyone tested/implemented these versions together?

Best Regards,

Emanuel
