我有Windows 8.1 64位，VS 2012 32位，IIS 8.5，IIS Express 32位。
WcfService项目目标框架：.NET 4.5 - ImageRuntimeVersion：v4.0.30319
IIS 8.5中托管的服务.NET 4.5 - ＆gt;引用Oracle.DataAccess.dll ProcessorArchitecture：Amd64版本：4.121.1.0
ERROR执行OracleConnection.Open
Oracle.DataAccess.Client.OracleException at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck, Int32 isRecoverable)

at Oracle.DataAccess.Client.OracleConnection.Open()
使用带有x64的AnyCpu和WcfService项目的WcfService项目出错 我也在oracle.dataaccess.client部分使用DllPath测试，我得到了同样的错误
现在在IISExpress（x86）中托管的相同服务NET 4.5 - ＆gt;引用Oracle.DataAccess.dll ProcessorArchitecture：X86版本：4.121.1.0 确定执行OracleConnection.Open
任何建议，如何调试或获取有关ODP.NET的日志，并获得解决方案？有可能吗？
我使用Target Framework再次测试：.NET 4.0，我得到了相同的错误（CLR 4.0 - v4.0.30319与.NET 4.0和4.5相同）
我也使用DllPath测试，但错误。
