asp.net - 错误 500.19 无法读取配置节 'oracle.manageddataaccess.client'，因为它缺少节声明

Question

我是 IIS 新手，我正在尝试在服务器的 IIS 上安装 Web 应用程序，但在运行时它显示一条消息“配置部分 'oracle.manageddataaccess.client' 不能阅读，因为它缺少节声明”，当我将它安装到我的计算机上时(如果它有效)，但是当我将它传递到服务器时，它会向我发送消息，我的应用程序是在 asp mvc 中制作的，并且我连接到 Oracle 数据库 11g

 100:   </system.data>
  101:   <oracle.manageddataaccess.client>
  102:     <version number="*">

这是我的网络配置

Answer 1

使用<oracle.manageddataaccess.client> web.config 中的元素，需要将其注册为 <section>或<sectionGroup>里面的元素 <configSections> 。您应该取消注释这部分，因为在您的示例中它仍然注释:

<section name="oracle.manageddataaccess.client" 
         type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />

如果取消注释该行仍然不起作用，请将其更改为 <sectionGroup>元素:

<sectionGroup name="oracle.manageddataaccess.client" 
              type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />

还要确保 ODP 托管数据访问已在您的项目和/或 GAC(全局程序集缓存)中注册为程序集引用。
