Subject: UFS direct I/O ?

Hi list,

Anybody out there running Oracle 9.2.0.4.0, Solaris 9 64-bit on UFS mount oracle datafile filesystem with forcedirectio option and set the init.ora parameter filesystemio_options to setall? What kind of performance gain by doing this?

BTW, our application is SAP R/3 4.6C.

Thanks,
