我在adoconnection中建立连接时，选ole db for oracle后，设置好连接oralce的参数（绝对正确）后，点测试连接，报如下的错误。
---------------------------
Microsoft Data Link Error
---------------------------
Test connection failed because of an error in initializing provider. Oracle error occurred, but error message could not be retrieved from Oracle.
---------------------------
确定
---------------------------
我想我的系统是出问题了，请教怎么修复！
