Here are the steps to set up the NFS ODM library file:1. cd $ORACLE_HOME/lib2. mv libodm11.so libodm11.so.ORIG3. ln -s libnfsodm11.so libodm11.soOnce the setup is complete, you will list the file to confirm that it is pointing to the rightfile:DBA11g1 > ls -l libodm11.solrwxrwxrwx 1 oracle oinstall 14 Sep 5 09:02 libodm11.so -> libnfsodm11.soNext, create the oranfstab file in the $ORACLE_HOME/dbs directory. Since Oracle first looksfor the oranfstab file in the $ORACLE_HOME/dbs directory, DBAs can implement Direct NFS withoutthe Unix system administrator’s intervention.The oranfstab file is not a requirement to implement Direct NFS. The oranfstab file is aspecial file to list additional options specific for Oracle Database to Direct NFS. The oranfstabfile has the following attributes for each NFS server to be accessed using Direct NFS:• Server: NFS server name• Path: IP or hostname of up to four network paths to the NFS server• Export: Exported path from the NFS server• Mount: Local mount point for the NFS server■Note For RAC implementations, you must use the oranfstab file from /etc. The oranfstab file mustbe synchronized across all the RAC servers.For our simple demonstration, we will just have one entry in the oranfstab file. Thecontents of the oranfstab file look like this:DBA11g1 > cat oranfstabserver: nas103path: 192.168.1.103export: /apps/oracle/share mount: /oradataAn example of an oranfstab with multiple paths looks like this:server: nas103path: nas1path: nas2path: nas3path: nas4
