Hi Dan, yes, I have created two domain services representing/managing connections to those two databases. On PostConstrunct of each of them I create two Datanucleus PersistenceManagerFactories and the domain service methods use appropriate Dao's creating the PersistenceManager and managing the transactions manually as needed. I can gladly share my code if you wish to review it or give me some feedback.
