Is it possible to connect a Ora DB using JDBC connectivity through .NET? If so what are the steps to install JDBC and configure the same and using which I can connect to the DB through C# code?
There's no way to do this out of the box, JDBC runs inside Java and there's no native way to call it from .net
Someone did create a third party package that enables this: http://codemesh.com/products/juggernet/examples/jdbc.html
That said, I can't see why you would ever want to do it when you could just use Oracle's .net provider instead.
