refer: http://www.netapp.com/library/tr/3369.pdf
FYI:
forcedirectio is an NFS mount options relevant in a Solaris environment.
It is not used for Linux clients.
I also see that referenced PDF has no mention of the
filesystemio_options parameter either. Ugh.
For a Linux client, use:
rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0
Now, 9i does require a patch with the Linux port so that Oracle will do
an open(,O_DIRECT,) of NFS files subsequent to setting
filesystemio_options=DirectIO
I'll have to dig for that patch number.
Hmmm...blog entry time
maybe it works.

Per note 359515.1 nfs mounts are supported for datafiles with oracle 10.
Does anyone know if the same applies for 9.2 databases? I urgently need
to create a clone of a 9.2 environment, but suprise surprise don't have
disk space available directly attached to the server. And yes I have
opened a tar, but figure someone where must have done this, been bitten
etc etc.
