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
oracle集群中plsql连接配置：
db_1_2 =
(DESCRIPTION =

(LOAD_BALANCE=yes)
