After successfully testing my MVC4 programs using this environment
I tried to publish it to 64-bit Windows 2008 Server with the IIS that disallows 32 bit apps, then I start getting stuck with the exception : the referenced dll's dependencies cannot be found!
I tried every advice the internet can give me including modifying web.config to reflect their dlls' on deploy-to server win 2008 using global cache cmd's on the prompt!
Yet nothing works. 32-bit is working but 64-bit is flat broke!

First, I stopped messing around the web.config. Then, I re-installed Oracle 11g 64 on my Windows 2008 server. Finally I placed ODAC on top of 11gx64's installation. The key to success is locating the correct ODAC to match the version of Oracle you have on your system.

To VERIFY you have the right ODAC installed correctly over oracle 11 g you have to look into [asp.net] and [ODP.net] directories to make sure they BOTH have 2.x's and 4's dirs in each bin and their presence in global cache 64.
Ater solving the ODAC installation problem, I start experimenting with oracle client dll's. I copied the Oracle.DataAccess.dll(64-bit) from bin [2.x] to my app's compiled bin only to watch my program still crashed with the same complaint that it cannot find the dependent DLL's. Then I copied the Oracle.DataAccess.dll from bin [4], then everything WORKS fine!!
Now the remaining question is why 4.112.4 not found in register cache GAC_64 is working great but the set of dll's registered in GAC_64 broke the program? Can't help not being confused.
See the resulting view of the working dlls ==>
If you acquire all those screens I show in this case, your MVC4 apps should fly high with Oracle 11 g 64-bit client! Good luck! I'll share mine with you!
