Procedure

Create NFS Share on Narrabri

Using the admin web interface on NARRABRI, I created a NFS share called COURSERA_NFS. (See 04 Setting Cloud for IaaS 3 for a similar set-up.)

Create Mount Point

On COURSERA, I created the following mount-point as the oracle user: 

mkdir -p /opt/app/oracle/oradata/coursera

Set Up File System Options

On COURSERA, I created the following file system as the root user: 

cat >>/etc/fstab <<DONE
narrabri.yaocm.id.au:/data/COURSERA_NFS /opt/app/oracle/oradata/coursera nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600
DONE

Enabling Direct NFS Client

The procedure given in 8.4.10.7 Enabling Direct NFS Client is incomplete. The environment variable, ORACLE_HOME , must be set prior to invoking make .

As the oracle user, I ran the following commands: 

export ORACLE_HOME=/opt/app/oracle/product/12.1.0/dbhome_1
cd ${ORACLE_HOME}/rdbms/lib
make -f ins_rdbms.mk dnfs_on

The output was: 

rm -f /opt/app/oracle/product/12.1.0/dbhome_1/rdbms/lib/odm/libnfsodm12.so; \
    cp /opt/app/oracle/product/12.1.0/dbhome_1/lib/libnfsodm12.so /opt/app/oracle/product/12.1.0/dbhome_1/rdbms/lib/odm/libnfsodm12.so
