Home -> Community -> Mailing Lists -> Oracle-L -> RE: performance issues on sun
I did this and its taking the same amount of time. The difference this time is that it does not do the KAIO call. But the time has not improved. Its still doing pwrite calls.
TIA Babu

I think you have hit the nail on the head. By default, the Oracle port on Solaris sets 'disk_async_io' to TRUE. Set this to FALSE by introducing such an entry in init.ora. Let us know if tihis solves your issue...
