tough job to abandon Oracle DB
I don't believe you could find a single entity running Oracle DB that is using the DB standalone. Folks are running specific applications that require Oracle DB as the backend. This is "safe" for the application vendor - how can you possibly go wrong with Oracle as your data store ?? But more and more of these app vendors are also listing MS-SQL as supported. And a large percentage of the small - medium size users are making that switch, or considering it. Your opportunity would not be to get customers to go open source, but to get app vendors to go open source. And there are few of those who have the huevos to abandon Oracle or MS.
