1.The /etc/hosts file must contain the following information.
127.0.0.1 localhost.localdomain localhost
# Public
192.168.2.101 rac1.localdomain rac1
192.168.2.102 rac2.localdomain rac2
#Private
192.168.0.101 rac1-priv.localdomain rac1-priv
192.168.0.102 rac2-priv.localdomain rac2-priv
#Virtual
192.168.2.111 rac1-vip.localdomain rac1-vip
192.168.2.112 rac2-vip.localdomain rac2-vip
#NAS
192.168.2.101 nas1.localdomain nas1
2.create shared disks
First we need to set up some NFS shares. In this case we will do this on the RAC1 node, but you can do the on a NAS or a third server if you have one available. On the RAC1 node create the following directories.
mkdir /share1
mkdir /share2Add the following lines to the /etc/exports file.
/share1 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/share2 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)Run the following command to export the NFS shares.
chkconfig nfs on
service nfs restartOn both RAC1 and RAC2 create some mount points to mount the NFS shares to.
mkdir /u01
mkdir /u02Add the following lines to the "/etc/fstab" file. The mount options are suggestions from Kevin Closson.
nas1:/share1 /u01 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0 0 0
nas1:/share2 /u02 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0 0 0Mount the NFS shares on both servers.
mount /u01
mount /u02Create the shared CRS Configuration and Voting Disk files.
touch /u01/crs_configuration
touch /u01/voting_diskCreate the directories in which the Oracle software will be installed.
mkdir -p /u01/crs/oracle/product/10.2.0/crs
mkdir -p /u01/app/oracle/product/10.2.0/db_1
mkdir -p /u01/oradata
chown -R oracle:oinstall /u01 /u02
