Hi Folks
For seeing that direct_io is enabled is this the only method
trace the dbwr session and then see that dbwr opens the file in
DIRECTIO in the open system call.
open("/tmp/test.dbf", O_RDWR|O_SYNC|O_DIRECT|O_LARGEFILE) = 21
I am on redhat Linux Advanced server 3.0
regards
Hrishy

I may be in left field here, but according to this article oracle doesn't take advantage of direct i/o on linux...
It says direct i/o is "available (2.4 kernels), not yet used by Oracle"

This article was published 2002. So this could no longer probably be true. I'll check if I have time the kernel versions of linux o.s. later.
