<private IP node1> <private hostname node1>
<private IP node2> <private hostname node2>
<public IP node1> <public hostname node1>
<public IP node2> <public hostname node2>
<virtual IP node1> <virtual hostname node1>
<virtual IP node2> <virtual hostname node2>

<public hostname node2> oracle
<virtual IP or hostname node1> oracle
<virtual IP or hostname node2> oracle
