ODAC连接远程Oracle数据库时,数据源名称orcl改为gscloud

今天用ODAC连接远程Oracle数据库时，怎么也连接不上，

更改配置文件的tnsname.ora，使之都一样，并完全配置正确还是出现错误，连接不上。

最后请大神一世，原来是数据源名称的问题。

把数据源名称orcl改为gscloud就可以了。

ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 223.223.179.17)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

把以上改为：

GSCLOUD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 223.223.179.17)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
