解决An attempt was made to load a program with an incorrect format.问题

有一个项目使用到Oracle Client，然后部署的时候出现以下问题。

Could not load file or assembly '*******' or one of its dependencies. An attempt was made to load a program with an incorrect format.

由于Oracle Client提供的DLL是32位的，因此需要在Application Pool建立32位的Pool来解决问题。
