Oracle RAC Listener configuration is the same as the single-instance configuration
11g after installing the RAC process, do not need to execute NETCA to manually create the monitoring, when installing the cluster software, will automatically create a listener;
The Tnsname.ora file is created automatically when the DBCA is built.
