    TWO NODES
    $/home/oracle
    mkdir .ssh
    chmod 777 .ssh
    ssh-keygen -t rsa
    ssh-keygen -t dsa

    SINGLE NODE
    ssh rac1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    ssh rac1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
    ssh rac2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    ssh rac2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
    scp authorized_keys rac2:/home/oracle/.ssh
    scp known_hosts rac2:/home/oracle/.ssh

    BOTH NODES
    $/home/oracle
    mkdir .ssh
    chmod 777 .ssh
    ssh-keygen -t rsa
    ssh-keygen -t dsa


    NODE1 Only:

    ssh rac1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    ssh rac1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
    ssh rac2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    ssh rac2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
    scp authorized_keys rac2:/home/oracle/.ssh
    scp known_hosts rac2:/home/oracle/.ssh
