System.Data.OracleClient.OracleException:ORA-12154: TNS:could not resolve the connect identifier spe

        最近接手离职同事的项目，交接进行了30分钟，牛人直接给了我一个.7z的压缩包，然后电话不接，QQ消息不回，失踪了。
没法，将压缩包解压出来之后，打算编译一个版本准备先发布到服务器上去

项目环境：

VS2010 + MVC3 + ORACLE，

服务器环境：

PL/SQL Developer
  Version 7.1.1.1339
  Windows Vista (64-bit) 6.0 Build 6002 (Service Pack 2)

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

PL/SQL Release 11.2.0.1.0 - Production

CORE 11.2.0.1.0 Production

TNS for Linux: Version 11.2.0.1.0 - Production

NLSRTL Version 11.2.0.1.0 - Production

 

X86下本地测试一切正常，

于是乎编译X64往64位Server 2008服务器上放的时候发生错误-

System.Data.OracleClient.OracleException:ORA-12154: TNS:could not resolve the connect identifier spe

当前服务器上有一个老的版本，并且应用程序池设定不兼容32bit,能够正常运行，PLSQL也运行正常，数据库操作正常，可就是新部署的新版本网站不正常，报错信息如下。

我发现这个Exception来至于System.Data.OracleClient.OracleException ，

1>我下载了一个64位的System.Data.OracleClient.dll测试，问题依旧，

2>我在程序池中设定兼容32位，然后本地BUILD 一个x86的包部署，不但所有DLL无法加载，老的版本也跟着报错

3>改回设定默认：不兼容32位，然后本地BUILDX64,ANYCPU的包部署，问题依旧，
