ODP.NET

Hello forum, I've developed an application with Oracle. In the machine client I've installed an Oracle Client, and it's well configured and runs correctly.

However, when I want to use my installed application, it doesn't run correctly. What is the best configuration in order to use in a machine that has installed an OracleClient (using ODP.NET or direct access to OracleClient?)

If I use ODP.NET --> Oracle.DataAccess.dll must to be accessible from my program, and i must be compatible with Oracle version.

Other question --> If I use Oracle.DataAcess.dll (ODP.NET), Has Oracle Client to be installed in final user machine?

I'm using NHibernate using ODP.NET (Oracle.DataAccess.dll) and it crashes -->

NHibernate.ADOException: could not execute query
