This note provides steps to update 11gR2 Grid Infrastructure (CRS) Single Client Access Name (SCAN) setting or SCAN listener port setting if it's not setup properly or if it's changed after setup.


1. This procedure does not apply when GNS is being used
2. Even though clustername and SCAN name is set to the same during 'typical' installation, changing SCAN name will not affect clustername as change of clustername requires deconfigure and reconfigure of the entire cluster.
