The first real day of this Openworld started off with a PLSQLChallenge 'live'. Good fun as alway, but this time no prices to win. The second session was about integrating Adobe Flash into Application Express. My idea is: ok, you can do it, but why would you? Just because you can?
After that Lucas and Alex did a good job about "Xenogentics" as they cold it. It was all about Java best practices for PL/SQL developers. Some fine and good ideas, but some I never would use in a real environment, because they are too complicated to implement and maintain. But the whole idea too look further than your regular scope for some good practices is very useful.
Then I attended a session about replacing mod-plsql modules in an eBusiness Suite with APEX. Mainly because mod-plsql isn't supported in an eBS12 environment. The presenters mainly focussed on getting the security stuff - authentication and authorization - right. Good stuff if you're in that situation.
The last session of the day was about Exadata. Rich Niemiec covered all hard- and software features that are in that box / machine / appliance.
After all those sessions it was good to wind down a little at the ODTUG meetup and the OTN night.
