-- key points
1. The value of the load_balance parameter is yes, which means the connection is in load balancing mode, and the value is no, which means that the non-load balancing mode is used.
2. The value of this parameter of method is basic, which means that there is only one connection node for the initial connection, and the value of preconnect means that Initially connect all rac contacts
3. The server parameter value dedicated indicates dedicated server mode, which is not practical and can be removed
