Goal

The purpose of this document is to provide information about the Direct NFS client and Step by Step to configure Direct NFS client.

Note :-The following steps are purely provided for evaluative and educational purpose only.Any issues with configuring the NFS server/client on Linux ie PART A ,you need to contact your Vendor.Oracle will not provide support/troubleshoot PART A.

 

WARNING:
The DNFS Guide says to enable the init.ora param filesystemio_options to enable direct I/O support.
Doing this, all DB access to all files will be via DIO.
There is no way to only enable direct IO for certain files and exclude others.
So ensure ALL the places where are located your database files (including pfile/spfile, logs,....) are configured to accept Direct IO.
