You could set in fstab ipaddress instead of the server name, so there is
no need for name lookup or you can put the ip and name in /etc/hosts

Where the nameserver is? On the backup server or on the oracle (or on
completely separate machine?)
- If on oracle server, you could make that one to start before oracle in
init.
- If on separate machine you could write your own init script which
tests that the name resolution works and runs the oracle startup after that.
I would put the ip in hosts if the backup server has fixed ip-address.
If not then making special init-script could be the trick.
