[英]Why would AllocateStreamingResources fail with error code 0x80004005?
[英]OleDbException (0x80004005): Oracle client and networking components were not found. How can I fix this?
我想用我的 web 应用程序中的 oledb 连接(msdaora.dll)连接到 oracle。
我用 :
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:
Server Error in '/PPIGanTT' Application.

我之前尝试过的:
1 - 在 iis 中,我将enable32applications
更改为true
。
2 - 将我的连接类型从oledb
为oracle.data.access
但它也不起作用。
3-- 我想找到 64 位 msdaora.dll 但我找不到。
我能做些什么来解决这个错误? 谢谢。
我有一个类似的问题。 根本问题是我的平台目标是Any CPU
。 有两种解决方案对我有用:
我认为 IIS 正在决定它将使用哪个(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,这是在 PATH 环境变量上切换项目的问题。 即我放置了这个:C:\Oracle\product\11.2\bin; 在此之前:C:\Oracle\product\12.1.0\dbhome_1\bin; 对于不同的公司,这些路径部分会有所不同。 然后需要记住将 PATH 上的项目切换回以再次使用 Oracle 12。
