Ravi,
If you are using host names instead of IP addresses in tnsnames.ora/init.ora
files - work with your SA/DNS administrators to either adjust the TTL (time
to live) for A records in DNS beforehand (1-3 days before - subject of your
current TTL settings) or flush nscd cache after re-IP on all other boxes to
avoid surprises after the move. This is a very common practice and your UNIX
SA should be aware of that - but it never hurts to double check.
