oracle集群中plsql和java程序连接方式非集群中plsql连接配置：
    DB1_193 =

    (DESCRIPTION =

    (ADDRESS_LIST =

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

    )

    (CONNECT_DATA =

    (SERVICE_NAME = bester)

    )

    )

    非集群中java连接的url

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