Well, in the case of changing the cluster name, I don't think adding/dropping a node will work, since the cluster name is defined when the cluster is created. In my case, I had all the nodes in my cluster change names. When that happens, the cluster is 'broken'. I don't think I would have been able to drop/add each node, since there was not a functional cluster to drop/add nodes? So, following the procedure in Alex's blog was easier/faster than uninstalling/reinstalling all the cluster software. -Mark -- Mark J.

Is there an advantage in doing all of this rather than just, as the metalink suggests (and I *hate* to side with metalink on *anything*), drop and re-add the node? ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Bobak, Mark Sent: Thursday, November 13, 2008 5:17 PM To: aleon68@xxxxxxxxx; oracle-l Subject: RE: Change RAC name Alfonso, I think it's officially not supported, but it's possible, if you follow the procedure here: http://www.pythian.com/blogs/482/changing-hostnames-in-oracle-rac I used the above to rebuild CRS without having to reinstall, after changing hostnames and cluster name. It worked well for me. -Mark -- Mark J. Bobak Senior Database Administrator, System & Product Technologies ProQuest 789 E. Eisenhower, Parkway, P.O.
