甲骨文净ManagedDataAccess错误：未能从程序集加载类型“OracleInternal.Common.ConfigBaseClass” [英] Oracle .Net ManagedDataAccess Error: Could not load type 'OracleInternal.Common.ConfigBaseClass' from assembly

问题描述

我有本地工作，我们的开发服务器上，而我们的生产服务器上的一个项目。

I have a project that works locally, on our dev server, and on our production server.

当我试图在测试服务器上运行它，我得到下面的错误，我不知道在我的屏幕做些什么超越楞。提示？流程追溯问题源头？

When I try to run it on the test server, I get the error below, and I don't know what to do about it beyond stare at my screen blankly. Hints? Process to trace the issue to its source?

我已经安装了的NuGet包甲骨文12.2等。

I've installed the NuGet package for Oracle 12.2, etc.

在web.config具有以下块吧：

The Web.Config has the following blocks in it:

  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    <section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
  </configSections>

和

  <oracle.manageddataaccess.client>
    <version number="*">
      <dataSources>
        <dataSource alias="PVMDataSource" descriptor="(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=pdxcludds108.pacificorp.us)(PORT=11086))(CONNECT_DATA=(SERVICE_NAME=DDS1086.PACIFICORP.US))) " />
      </dataSources>
    </version>
  </oracle.manageddataaccess.client>
  <connectionStrings>
    <add name="OracleDbContext" providerName="Oracle.ManagedDataAccess.Client" connectionString="User Id=USERID;Password=WORKINGPASSWORD;Data Source=PVMDataSource" />
    <add name="PVMEntities" connectionString="metadata=res://*/Models.PVMModel.csdl|res://*/Models.PVMModel.ssdl|res://*/Models.PVMModel.msl;provider=Oracle.ManagedDataAccess.Client;provider connection string=&quot;DATA SOURCE=pdxcludds108.pacificorp.us:11086/DDS1086.PACIFICORP.US;PASSWORD=XXXXXXX;PERSIST SECURITY INFO=True;USER ID=XXX&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>

注：有此服务器上工作的其他项目，他们只是使用不同版本的Oracle客户端对于.NET的。其他的没有仅使用管理驱动程序。我要寻找一种方式来挖这个错误，有的提示，如该类型的来源和加载。

NOTE: There are other projects working on this server, they're just using a different version of the Oracle client for .Net. None of the others is using only the Managed driver. I am looking for a way to dig into this error, some hint as to where that type is sourced and loaded from.

推荐答案

之所以能够从由包管理器安装的那些由安装那些在项目Oracle.ManagedDataAccess和Oracle.ManagedDataAccess.EntityFramework更换引用修复oracle的客户端安装程序。该版本是相同的，但版本号是这些DLL

Was able to fix it by replacing references in the project to Oracle.ManagedDataAccess and Oracle.ManagedDataAccess.EntityFramework from those installed by the package manager to those installed by the oracle client installer. The versions are the same but the build number is different on those DLLs
