What is a SCAN name ?
Oracle introduced this new concept on 11gR2 version: it stands for Single Client Access Name (SCAN). Its purpose is to eliminate the need to change tns name entry when nodes are added to or removed from the Cluster. What does it happen when you have several client and you decide to add/remove a node? So you have to configure your SCAN name
enter scan name as either rac1 or rac2(basically it should be one of the nodes of the cluster and click on Configure GNS
Click next
Click add button and add the second node
click next
Click Next
Click Next
select ASM
Enter the Disk group name and the candidate disks needed for discovery path
Click next
select the appropriate passwords for SYSASM user.
click next, DO NOT CHOOSE THE FAILURE ISOLATION OPTION FOR THIS INSTALL PURPOSE
Click next
Click next, you may get warning message depending the complexity of the password chosen.
