Question

我在IIS上收到引用我的Oracle数据连接的错误500。我已经附加了堆栈跟踪。我已经验证我安装了Oracle客户端，并且DLL都存在于应用程序目录中。我正在运行带有IIS 8.0的Windows Server 2012。附件是我的堆栈跟踪...

我确定我的 SOMETHING 配置错误。基本上我希望这个站点能够从dev移动到生产，我已经设置了Oracle.DataAccess的引用来复制本地，它会复制到bin文件夹，所以我的理解是它应该引用那个dll而不是服务器上的任何东西。但是我确实在服务器上安装了版本为11g的客户端，所以也许我引用了那个错误。 这是在64位版本的Server 12上运行的32位应用程序。

您正在为已安装的Oracle客户端版本使用不兼容的提供程序。这就是发布的堆栈跟踪所指的内容，如下所示

"ExceptionMessage":"The provider is not compatible with the version of Oracle client"

检查您的config文件并进行相应更正。
