Hi Andrew, 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 Martin Bach Oracle Certified Master 10g http://martincarstenbach.wordpress.com http://www.linkedin.com/in/martincarstenbach ----- Reply message ----- From: "Andrew Kerber" <andrew.kerber@xxxxxxxxx> Date: Thu, Feb 3, 2011 18:27 Subject: 11gr2 Clusterware config (or: does anyone know what an endpoint is?) To: "Surachart Opun" <surachart@xxxxxxxxx> Cc: "ORACLE-L" <oracle-l@xxxxxxxxxxxxx> 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.
