I know its too late to answer. But this might help someone else. I was initially working with MS SQL and Crystal report in my .NET MVC application. But the client was using Oracle and my application needed to contact a remote oracle DB. The connection was working fine but the connection of crystal report and oracle was giving intermittent issues.

So the final fix was to create DataSets. In my application before generating the report, I populated the DataSet with data from Oracle. And used the DataSet as the Data Source for my report. It works great now.
