I tried following the instructions for changing the IP in the document http://download.oracle.com/docs/cd/B32110_01/core.1013/b32196/host.htm#CIHHADCE, but it kept erroring out with ‘file not found’ errors. As a quick and easy work-around, I bound the old IP to the loopback and voila!
create the file /etc/sysconfig/network-scripts/ifcfg-lo:1 like so:
DEVICE=”lo:1″
IPADDR=”PUT_YOUR_OLD_IP_HERE”
NETMASK=”255.255.255.255″
