Oracle two kinds of common ways to configure URL and java connection

1. Ordinary SID instance name configuration

　jdbc:oracle:thin:@136.155.131.111:1521:dzyw

     Java connected in such a way: url = jdbc: oracle: thin: @ 136.155.131.111: 1521: dzyw

2.RAC (cluster connected) Configuration

　jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 136.155.131.111 )(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME = dzyw)))

   The cluster approach in java connection: url = jdbc: oracle: thin: @ (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = 136.155.131.111:1521) (PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = dzyw)))
