I have a 2 node Oracle RAC cluster, one of them got frozen from time to time. So I have to replace it with a new server. I already set up the new server with ORacle Linux 5.3 and use "yum install" upgrade the OS (we have service contract with Oracle). I also read this document http://www.databasejournal.com/features/oracle/print.php/3929556
but don't know where should I begin. Experts here, do you have any reference.
Our DB is oracle 11g R2.
