You have to do it both with oifcfg, and I think you have to use srvctl as well. One changes it, and the other registers it. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Roman Podshivalov Sent: Thursday, September 18, 2008 11:27 AM To: eglewis71@xxxxxxxxx Cc: oracle-l@xxxxxxxxxxxxx Subject: Re: changing ip interface in a cluster Hi, I performed RAC re-ip in the past by following that note, one node went fine, but other had some issues, cannot recollect what exactly. To fix them I had to use crs_unregister to remove all related stuff and re-run vipca to recreate them with correct IPs. Also make sure to work with your SA to adjust TTL in DNS or whatever name resolution system you are using internally to avoid flushing name cache on the clients. --romas On Wed, Sep 17, 2008 at 8:30 PM, ed lewis <eglewis71@xxxxxxxxx> wrote: Hello, The ip addresses for the VIP and public interfaces are going to be changed in our cluster. I found a paper on metalink, that recommends using the oifcfg utility to do this. Basically, shut down the cluster and change the ip's using this utility. Has anyone done this, and are there any other issues I should consider. Thanks for your help. ed solaris 5.10, oracle 10.2.0.4 <http://10.2.0.4/>
