I have 2 questions 1)Do we need to install Clusterware on node 2 before converting to RAC or rconfig will take care of it. 2)What if the second node has configuration issues, and how rconfig will take care of it ?
Ans 1: YES YES and YES... RAC is clustered nodes... so Clusterware must be installed. Ans2: rconfig is only a tool to help convert SI to RAC... if there are underlying issues, rconfig more than likely will fail. That is why you run rconfig with ONLY option to check first before executing
Great question... Yes, the single instance is shutdown and restarted multiple times and a new rac instance is created. Therefore, existing connections will be dropped as that single instance goes down
