Mounting NFS Storage Devices with Direct NFS Client

Direct NFS Client determines mount point settings to NFS storage devices based on the configurations in /etc/mtab, which are changed with configuring the /etc/fstab file.

Direct NFS Client searches for mount entries in the following order:

1. $ORACLE_HOME/dbs/oranfstab

2. /etc/oranfstab

3. /etc/mtab

Direct NFS Client uses the first matching entry found.

Oracle Database is not shipped with Direct NFS Client enabled by default. To enable Direct NFS Client, complete the following steps:

1. Change the directory to $ORACLE_HOME/rdbms/lib.

2. Enter the following command:

   make -f ins_rdbms.mk dnfs_on
