Hi Steve, when explicitly setting the Dialect to an empty string I have several failures; when leaving it as-is I believe this run was valid though, at least that's the feeling I'm getting from the kind of failures: http://ci.hibernate.org/view/ORM/job/hibernate_orm_master_oracle/ws/hiber... Some tests are failing, but a significant amount is passing just fine and the logs seem to indicate that it's using the Oracle testing instance. Also, setting the dialect seems consistent with other matrix configurations? Thanks, Sanne
