ODTUG Kaleidoscope 2008 : Day 4 - ADF vs APEX and Wrap Up

The last morning of this years ODTUG was completely filled with one three hour session: APEX versus ADF 'shootout'. Although the presenters, Lucas and Dimitri, quickly stated that there was no violence to be expected, the audience was hoping for some clear statements.

Lucas and Dimitri both built an application using their favorite tool and demo'ed it to the audience. Both failed on one part - as live demo's tend to do - so it was 1-1 at mid time. After the break the match continued with some nice features shown on both sides. Both presenters where dared to say something positive on the other tools. For Dimitri this was the most difficult part: "I can't come up with anything nice to say about JDeveloper".

After a complete comparison, there was one clear winner: The audience!

Thanks to both of you guys for this joint effort!

So to wrap up: ODTUG is a great event. Not great in the sense that you're overwhelmed with 1,000's of people (there were about 700 attendees), but exactly the opposite. Due to the fact that it is rather small, you'll find yourself having a beer (or two) with all kind of guru's, experts, co-bloggers etc. Especially that relaxed, cool atmosphere is what makes ODTUG such an excellent event.

One more note about 'atmosphere': New Orleans in June is so hot and humid, that you barely can stand the outside temperature for more than 10 minutes - on the opposite : inside (in particular inside the Sheraton) the air conditioning is turned to the max. So every time you get from the outside to the inside, or the other way round, you have to deal with a temperature difference that feels like a 20 C.

Also the Sheraton is a good place to stay and from the 43th floor I had a great view on the river. Could have been better if somebody had cleaned the window - but who cleans windows at that height?

I hope to see everybody again next year - in Monterey (?).

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid. The use case I'll cover right here is probably more common - and therefore more useful!

Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user.The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even worse) while you…

Using multiple Authentication Schemes for your APEX application

Recently someone asked me how he could implement multiple authentication schemes for his APEX application. He would like to use (some kind of) Single Sign-on authentication and - as an alternative - an Application Express Authentication. The problem is ... you can only define one Authentication Scheme being "Current" for an application! So how can we solve this issue?

First, we need te be aware that multiple applications can share their authentication by using the same cookie. Thus if you specify "MYCOOKIE" as the Cookie Name in Application A as well as in Application B, you can switch from A to B and back without the need of logging in again. It doesn't matter what Authentication Scheme Type you are using!

Knowing this, we are halfway our solution. We need two Applications. One - the "real" application - using the Application Express Authentication, let's name this one "LAUNCHPAD". And another one using the Single Sign-on Authentication…
