Having a blast bringing a small group of Online 5 users all the way up to Informix 11.5. Spent the week teaching my version of the IDS Sys Admin and DBA combo class. What an odd environment though – once the engine is setup, it won’t be changed most likely for years due to compliance w/ the FDA. One student said “we won’t upgrade until Informix 17 – since we only upgrade every 6 major releases!” It really has been different from a teaching point-of-view – the normal “and if you see [this], make sure you change ….” and then I’m reminded that changes won’t happen most likely. The engines are rather small, so it could be fine. But again – what a blast to teach again! Awesome.
