UKOUG 2014 - A special edition

Although I’ve attended the UKOUG conferences since 2008, this year’s edition was somewhat special to me. Based on the attendee reviews of last year’s UKOUG, I was elected as “Best Overseas Speaker”. And for me that’s quite an honour and of course a recognition for years of work - and practice ;-)
And with a title comes a plaque - it’ll get a special place on my bookshelf. 

I didn’t just get all the way to Liverpool to collect my award. I also did three presentations - from my point of view it was only 2.5, but I have to round up according to Brendan Tierney…
The first one I did was “Ten Tiny Things” about a couple of the less known new features of APEX 5. And I showed something even one of the APEX Development Team members didn’t know ;-) . The second one was together with Brendan (that’s why I usually count this one only as .5) about the things you can do with the Oracle Data Miner and Oracle Text features in combination with APEX. We both thought it went very well and we had some very positive feedback.
The last one - and even the last one of the conference - was the same presentation that won that prize last year about creating hybrid APEX applications. Although I have done this one quite some times, I still like doing it.
Apart from my bow presentations I attended some other ones of course. Especially the ones about NodeJS - one from John Scott and one from Alex Nuijten - got my attention. And of course the presentations of the APEX Development Team about APEX 5: You see some new stuff every time they show it. And getting more and more eager to get my hands on it !
Alas I had to miss some of the sessions, because a couple of rooms were so tiny, they could only hold like 20 people or so. So they “sold out” in minutes. Too bad - luckily that doesn’t happen in Birmingham (where the conference will be held again next year).
And apart from the sessions, it again was an excellent opportunity to hang out with all the old and new friends. Really enjoyed it again. Hope to see you all back in Birmingham next year!

Push changed rows to an Interactive Grid

For pushing changes from the database to the end user, the regular solution is using websockets. A change in a record is detected - using a trigger or using the CQN (Change Query Notification) feature - and a notification is send to a websocket server. That websocket server broadcasts the notification over a channel to all browsers that are tuned in to that websocket channel. Then the browser reacts to that notification, usually showing an alert or refreshing a report. This trick is described on multiple sites, just Google for "oracle apex websockets" or similar.

So back in the old days, we used that notification in the browser to refresh the (interactive) report. But along comes the Interactive Grid (IG). While he full-refresh mechanism still works for IG, an IG has also the option to refresh just one row.  So wouldn't it be awesome that just the changed row(s) get refreshed upon a change in the database, instead of the whole report? Can we do it ... yes we can!

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…
