asp.net中的ORA-12154: TNS: 无法解析指定的连接标识符

本机PL/SQL能正常连接，但是asp.net连接有问题。

临时解决方案：

 <add key="ConnectString" value="Data Source=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = xxx)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)));Persist Security Info=True;User ID=xxx;Password=xxx;Min Pool Size=3"></add>
