Creating a Cool Dashboard in APEX

In my current project I have to create a dashboards that reflects the actual (and historical) situation in a factory. At first I tried something like the dashboards Anychart provides on it's site, like this. It is possible to create that kind of stuff in APEX, but then you have to generate all the XML data by yourself. And the fastest way to do something is...don't do it at all.

So, since the subregion-feature of APEX 4, you can achieve the same results by only tweaking the Chart XML itself a "little". And now I have something like this:
Kinda cool huh? I also created an example on apex.oracle.com (refreshes every 3 seconds with random data).

UKOUG 2010 Recap - Wednesday

Wednesday I started late, because I skipped the first session to prepare for my second one "Tales from a Parallel Universe: Using 11gR2’s Edition Based Redefinitions". Went also pretty good as well I think, ended nice on time - even, again, with a session chair. And I received some really positive feedback from people like John King and Christian Antognini. Thanks guys!
Then there was a funny debate kind of session between Tony Hasler and Jonathan Lewis about "Does Oracle ignore hints?". In the end it was all about semantics...if you discard bugs, poor or wrong documentation and more or less hidden features and unexpected optimizer processes, Oracle never ignores your hint (which in fact is more a 'directive' than a hint) - otherwise you might say that Oracle actually does  ignore your hint.
After lunch - instead of the good hot lunches we received a school-like lunch bag this time - I chaired my second session : "Edition-Based Redefinition: Testing Li…

UKOUG 2010 Recap - Tuesday

Tuesday started of with a two hour Masterclass by Cary Millsap "Thinking clearly about performance". A really great session that explained clearly what performance actually is (so the content covered the title). Using with a lot of nice stories, examples and analogies Cary has the ability to explain stuff that seems difficult in a way everybody can understand. If you haven't seen this one, it is really a must see if you have the chance!
Because the next session on my agenda was shifted to another place and time a had some time to walk through my own presentation for that afternoon before attending the APEX Roundtable. A nice Q&A about what all APEX stuff. Some person from Oracle even gave us some insight on when to expect APEX 4.1, but I won't repeat the schedule, because he actually was not allowed to say that (but if you are really interested, I already tweeted about that...). After lunch I chaired Anthony Ashton's session about "Practical Oracle 11g XML…

UKOUG 2010 Recap - Monday

Compared to some other attendees I had a fairly easy travel back home from another great UKOUG conference. And now I finally have the time to look back and write a blog post about my experiences over seas. As usual I planned to do a daily blogpost, but - also as usual - I can't find the time during the conference to blog. All those "social commitments" in the evening...sigh... 
I'll split it in three, otherwise it will become too long.

At Monday I started of with Grant Ronald's "The Quick Start Guide to Fusion Development with Oracle ADF". A good session that covered baby's first steps in ADF Development. As always, as Grant shows is, it seems so easy... But, coming from a Oracle Forms/Designer background, to me JDeveloper is still a huge box with tons of options to me. But I think I've forgotten how impressed I was when I first opened up Designer - with also tons of options! So IMHO developing in JDev might be fast (and definitely can result in …
