I have a Web server running Windows Server 2008 64, with Oracle 11g 64.

I developing with Visual Studio 2013 under windows 7 32.

I have installed the odp in both machines (64 and 32 versions respectively) and net framework 4.5

To conect dbgrid by sqlDataSource i used odp managed, but if i try to use it in my code, i have problems in the server: 'Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies'

The question is:

- Is posible to do this whit my configuration?
- Is necessary to change my windows 7 machine to 64 bits?
- What conection is better - odp managed or oledb??? Whith oledb in my code i haven't any problems.

Do you have older .NET frameworks on your server? I think ODP works only with 2.0...
Check also that you have the latest ODP version...
