            YES-Require the DNS Server for fully configure the SCAN
            You can ignore to use DSN and use single scan inside the local /etc/hosts if you don't have separate DNS server

            Please find the details

              thanks for your reply.

              I am using linux 5.5 and oracle is 11g r2.

              1) is there any query or procedure to find DNS server.

              2) where this scan listener will be located. On DNS server or on local server.

              Thanks for you help and sorry for asking too many questions.

                Did you You already configured the RAC or you want to configure from scratch. ????

                You have to work with system administrator for configure the DNS server for RAC Server
                please Refer the below link

                2) where this scan listener will be located. On DNS server or on local server.
                No
                scan listener located inside the local server only

                Hope you got all information.
