Oracle 10g R2 RAC - IP address Change

447582Nov 9 2005 — edited Feb 18 2008

We succsessfully installed Oracle 10gR2 single database on two node RAC on Windows 2003. I followed the Oracle RAC installation documentation and assigned a public IP for the machine and another Virtual Public IP and a Private IP. We have also changed the "hosts" file in Windows to reflect the above mentioned confiuration. Here is a snippet of the "hosts" file in Windows.

xxx.xxx.xx.xxx NODE1
xxx.xxx.xx.xxx NODE1-VIP
192.168.1.161 NODE1-PRIV

xxx.xxx.xx.xxx NODE2
xxx.xxx.xx.xxx NODE2-VIP
192.168.1.161 NODE2-PRIV

After succsessful installation and testing for a few days, we are in a situation where we need to chanage the public IP's for NODE1-VIP and NODE2-VIP. If I change the IP's in the "hosts" file for NODE1-VIP and NODE2-VIP and restart the computer, both the nodes are not starting up and it comes back with a windows error. But If I change back to the old IP's, it works absolutely fine. How can we change the Virtual IP's associated for each node after a successful RAC installation?

Thanks.
