Enabling Direct NFS
You must follow these steps to enable Direct NFS:
1.You must mount all NFS mount points with your kernel NFS client. You must make sure you mount any file systems you plan on using through ODM NFS and make the file systems available to Oracle over regular NFS mounts.
2.If you want to specify Oracle-specific options to Direct NFS, you’ll need an oranfstab file. This is an optional step. The oranfstab file must have the following attributes so the database can access all NFS servers through Direct NFS:

3. You must replace the standard ODM library, libnfsodm10.so, with the ODM NFS library, as shown here:
$ cd $ORACLE_HOME/lib
$ mv libodmll.so libodmll.so_stub
$ ln -s libnfsodm11.so libodm11.so
