Re: 11gr2 Clusterware config (or: does anyone know what an endpoint is?)

There are 2 mos notes about how to change the scan post the installation. I have also bogged about it (see below for the link, I don't have the exact url to my post at hand right now). None of the solutions involves crsctl BTW, and I would definitely not use this command for ora.* prefixed resources.

Let me know if you can't locate the post and I will dig up the url.

Hope this helps,

Martin

I guess I didnt explain the problem. There are now 3 ips for SCAN, and they show up properly in DNS and in srvctl config scan, but according to Oracle I have to add another scan listener. I cant figure out the correct syntax of the command to add a scan listener, primarily because I dont know what a scan prefix or an endpoint is.
