1. Oracle非集群url配置

       非集群中java连接的url

　　url=jdbc:oracle:thin:@127.0.0.1:1521:bester

2. Oracle集群中url配置

     （1）Oracle集群中plsql连接配置：

　　db_1_2 =　( DESCRIPTION = 

            ( ADDRESS = (PROTOCOL = TCP)(HOST = 59.208.39.193)(PORT = 1521) )

            ( ADDRESS = (PROTOCOL = TCP)(HOST = 59.208.39.195)(PORT = 1521) )

            (LOAD_BALANCE=yes)

            (CONNECT_DATA =

                        (SERVICE_NAME = bester)

             )

           )

      （2）Oracle集群中java程序连接的url

datasource.url = jdbc:oracle:thin:@( DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST =59.208.39.193)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST =59.208.39.195)(PORT = 1521))

    (LOAD_BALANCE=yes)

    (CONNECT_DATA  = (SERVICE_NAME = bester))

)
