KScope 11 - Sunday

The first day (or pre-conference day) was filled with four full day Symposium sessions. The APEX one I attended was completely filled by the APEX Development team itself. 
Joel Kallman kicked the day off with a nice story about the development of APEX, the tools they used etc. Then there where three more sessions about Tablular Forms, Interactive Report and Webservices - all pointing out the new APEX 4.1 features. 
The coolest one of the day was Marc'Sewtz's presentation on APEX for Mobile Devices. He showed that, using HTML 5 in your template, you can create real native-looking applications for mobile devices. You can already do that using the current version of APEX, but the 4.1 will also contain support for special mobile actions, like rotate and tap - so you can create Dynamic Actions on these events. As jQuery Mobile, the framework they're using, isn't production yet, probably some of these mobile features will be disabled in the first release of 4.1. 
Mike Hichwa had the keynote as the last session of the day. He outlined the plans for APEX after 4.1. Next on the wish list are more cool functions like a Modal Dialog, Multiple File Upload etc. It seems that every good plug-in out there will be added as standard functionality! Als providing RESTful web services will be a feature of an upcoming APEX release  - using the power of the APEX Listener.Talking about APEX Listener...some BI Publisher functionality might be incorporated in the AL, so the AL then can be used for generating PDF documents - a sort of "BI Publisher Light"...
Last but not least: Did you know Oracle uses an APEX application for their partner store and orders with a total worth of 4 billion dollar go through it....so, who dares to say APEX can't be used for business critical applications and is only suitable for small department level ones?

Uploaded our "XFILES, the APEX 4 version - The truth is in there" presentation ....

Yesterday, June 15th, Marco and I did our first try-out of this brand new presentation during the AMIS ODTUG Preview. The next real appearance will be in two weeks in Long Beach during KScope11. It all went pretty well, we received some tips and tricks do it even better - so be there if you can!
The presentation can be downloaded from Slideshare or from http://xace.sourceforge.net/. On SourceForge you can also download the demo application...
And we still can use some votes for OOW Suggest-a-Session... (until June 19th).

OOW Suggest-a-Session : Top Voted Sessions

During the period the Suggest-a-Session for Oracle Open World 2011 on Oracle Mix is open, you can't see the rank of the (or your!) proposal. Only by accessing every proposal and writing down the number of votes, it is possible to get an idea of the rank of a proposed session. This is quite a cumbersome exercise...so why not automate this? Heavily inspired by Wilfred van der Deijl, who wrote a Java program to do that, I created a similar functionality using just the Oracle Database. Who needs Java after all ;-)
The first set up requires setting the ACL right for using utl_http. Next I had to import the certificate Oracle is using for that site into the Oracle Wallet Manager and then create a function that retrieves all proposals and filters the title, presenter and the number of votes. This takes a while, so I dumped the results in a table. 
Next I uploaded the results to my workspace on apex.oracle.com (couldn't run the procedure from that site as the ACL there prevents the use of utl_http) and created a Report and a Chart on top of it. So now you can see your rank (I will - try to - update the data every day).

As you can see the session Marco and I proposed still needs some votes, so when you like this overview, please vote for our session as a "thank you": https://mix.oracle.com/events/oow11/proposals/10930-xfiles-the-apex-4-version-the-truth-is-in-there !
