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
