Oracle 184.108.40.206 on SunOS 5.1
i have a client who is running a 2 node RAC environment but has shutdown the instance on one of the nodes. I was wondering whether after doing this they should change the database parameters on the remaining instance to reflect this, in particular i am thinking of parameters such as parallel..., cluster_database, cluster_database_instances, gcs_server_processes etc.
also, if they don't remove the node from the cluster services and grid control, is there a performance overhead? is just shutting down an instance a bad idea when it comes to performance if it is not removed correctly from the cluster?
