Configuring Oracle for Direct NFS

You can configure Oracle as a Direct Network File System (NFS) client by performing the steps in the following example procedure. In this example procedure, Oracle Database version 11.2.0.2 (single instance) is installed on a Linux box.

To configure Oracle for Direct NFS

  1. Mount the NFS file systems.

    See Recommended mount options for NFS.

    [orahost1]# mount -t nfs -o  \
rw,bg,hard,nointr,rsize=1048576,wsize=1048576,noac,forcedirectio,vers=3,suid  \   
virtual_IP:/oranfsdata  /oranfsdata

    Note:

    Use the virtual IP (VIP) in the mount command.
  2. Enable the Oracle Disk Manager (ODM) library that supports the Direct NFS client.

    Note:

    You must replace the standard ODM library with one that supports the Direct NFS client to enable the Direct NFS client.

    		 
    [orahost1]# cd $ORACLE_HOME/lib  
[orahost1]# mv libodm11.so libodm11.so_bak  
[orahost1]# ln -s libnfsodm11.so libodm11.so
  3. Set up oranfstab.

    See About oranfstab.
