I have an enterprise level application that is using .NET 3.0 Workflow Foundations, Oracle 10g on Unix. We are using workflow persistence and tracking from MS and storing wf data in a SQL db. Because we're using 10g for our app data, we need to use a distributed transaction coordinator to manage the updating of wf db and app db. I am thinking I won't be able to connect to the 10g db on Unix using MS DTC. Is this true? If I can't use MS DTC, what other options do I have to connect to Oracle on Unix under a distributed transaction?
