Make sure not to miss Fusion Middleware Summer Camps organized by Juergen Kress. I can confirm - Oracle training events organized by Juergen are the best. These training events are typically very well structured and consist lots of technical information. If you are looking for no marketing, but real technical training - go to Fusion Middleware Summer Camps.
More info and registration details read on Juergen's blog - Fusion Middleware Summer Camps & advanced partner trainings.
Available seats are limited - my advice is to register fast.
