ORCAN event

Yesterday I attended an event organised by the Swedish Oracle User Group (ORCAN). They picked a real nice venue for this meeting: the top floor (54) of the Turning Torso. From this top floor you have a stunning view over the Oresund (all the way to Copenhagen) and Malmö and it's surroundings. Might be a little bit distracting from the presentations, but nevertheless...
There were two concurrent presentations. The first one I attended was by Moren Egan about Edition Based Redefinitions. As I presented about the same subject at OOW and UKOUG, I was just curious about how he would present this material. More SQL*Plus oriented as I did it, but I think the message came across just fine. The second one was by Randolf Geist, called "Advanced Oracle Troubleshooting". In fact it was just the first half (the second half was after lunch). Although I could grasp most of he said, some details were a little bit over my head. So I skipped the second part and went to SQL Developer New Features by Sue Harper. I was already familiar with most of the features, but it's still worthwhile to renew your insight about this product. It is growing with every release!
Then it was my turn wih APEX 4 New Features. To my surprise 75% of the audience had no experience at all with APEX - so all features are new to them! But I emphasized and spent most of the time demoing the cool Dynamic Actions and Plug-ins. Just to show how you can create stunning results with almost no coding! After a short coffee break I presented about Charts & Dashboards. This time I had alomst all attendees in my class, as the "other side" only had 4 (sorry Sten). All went pretty well I think, but I have to admit, doing two presentations back to back is a little bit exhausting.
Then it was time to leave for dinner in the center of Malmö. When I got my jacket I noticed my pockets were empty - and I was pretty sure I left my car keys and phone in there (which isn't that smart, I have to admit)! So a little panic broke out. We contacted the reception, searched the whole place - but nothing found. But then I noticed that there was something else missing from my jacket: It had just the Oracle logo, and mine had Oracle ACE Director logo! So it wasn't mine! A quick thought whose jacket it could be...and it had to be Sten Vesterli. And Sten was on his way to Copenhagen... We phoned him, but got his voice mail. So we went to the restaurant...and there was Sten with my jacket. While walking to the station he noticed there was a phone in his jacket (or my jacket) and another one in his pocket. So he also concluded he had taken the wrong one - and decided to go to the restaurant to exchange jackets. A total relief for me. Thanks Sten - not for taking the wrong jacket, but for returning it ;-) !
We had a nice dinner outside on the square. This little square is packed with restaurants and everyone is sitting outside. So they have a lot of heaters (and I mean really a lot!) and blankets for everyone. So I think global heating is for a major part caused by the Swedish... ;-)
All in all a nice event and I am looking forward to the next one!

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…
