我想在我的web应用程序中使用oledb连接(msdaora.dll)连接到oracle。
我用途:

IIS 7.5
64 bit windows server 2008 r2 enterprise.
64 bit oracle 11g
32 bit oracle client

visual studio 2010
32bit msdaora.dll
my aplication is .aspx

我的错误是什么

我以前尝试过:
1--在iis中,我将enable32applications更改为true
2--将我的连接类型从oledb更改为oracle.data.access,但它也不起作用。
3--我想找到64位msdaora.dll,但找不到。
我可以做些什么来修复这个错误?谢谢。

我也遇到过类似的问题,根本问题是我的目标平台是Any CPU,有两种解决方案对我有效:
1.将平台目标更改为目标上现有(且唯一)Oracle客户端的CPU,在您的情况下为x86,或者
1.安装了缺少的oracle客户端,在您的情况下,为x64安装了msdora.dll。
我认为IIS正在决定使用哪个(x86或x64)msdora.dll,因为Any CPU平台目标编译。您必须要么取消IIS的选择,要么提供所有答案。

对我来说,这是一个切换PATH环境变量上的项的问题。即,我放置了以下内容:C:\甲骨文\产品\11.2\bin;在此之前:C:\Oracle\产品\12.1.0\dbhome_1\bin;这些路径部分对于不同的公司将是不同的。然后需要记住将PATH上的项切换回以再次使用Oracle 12。
