ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务

别人能连，我用pl/sql却连不上

仔细对比后发现是tns配置问题，管理员提供的是SID，而不是服务名

 

QQQQ =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.15.50)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME= orcl)
)
)

 

改为

 

QQQQ =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.15.50)(PORT = 1521))
)
(CONNECT_DATA =
(SID= orcl)
)
)
