Loud! 2006 - Our own OOW, but smaller…

On November 9th my employer, LogicaCMG, organised it’s own version of Oracle Open World, but just a little bit smaller. About 130 colleagues came to Amstelveen to listen to the keynote (after a good dinner) and after that three times a choice from one of the three parallel sessions. As usual the evening was very well organised (thank you committee!), but there was some experience as it was already the 7th version of this annual event.
The keynote speaker was Rob Blaauboer who enlightened us about Innov8 (the 8 should be the mathematical infinite sign, but I can’t find that one on my keyboard), a method to visualize what technologies a company should adopt or look in to in the nearer or farther future.

The first parallel session I visited was Oracle2Go by Reza and Robert. Oracle2GO is a framework as an extension of the ADF Framework, to develop applications faster and with higher quality. They mentioned a couple of success stories and proudly pointed out that they managed to achieve a productivity of 4 hours per function point (calculated according to the fpa standards of the Dutch NESMA): a productivity that is barely to improve in the ‘old fashioned” Designer/Developer approach!

After that Lex Borger told us about Identity and Access Management: he explained the problems around AIM and pointed out the different alternatives for solving these problems. Finally – as this was an Oracle related event – he mentioned the solutions Oracle offers.

The last session I choose was The Best of Breed of Fusion by Ivan Pellegrin. He stated that the Oracle product range is so gigantic nowadays, that the time you could know everything about all Oracle products (as in the time there was only a database, Forms 2.3 and RPT/RPF) has been long gone. So we have to choose our interests and specialise in that area. Form his point of view BI Publisher and WebCenter will get a lot of attention in the near future.

The evening was closed with a quiz (a sort of Jeopardy or 1-against-100) where the winner, he who knows the most (or guessed best) about Oracle related questions, received a Playstation2.

All in all it was a great evening and I’m already looking forward to the next one!

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

A review of APEX World 2017 - Day 1

Last week the SS Rotterdam was the beautiful location of the largest gathering of APEX Developers worldwide. With around 380 (!) attendees a new high was set. And they came from all over the world : I spotted people from The Netherlands, Belgium, Switzerland, Austria, Croatia, Germany, Denmark, Norway, UK, Ireland and the USA. And I even might have missed one or two ….

The event started with a presentation by the “father of APEX”, Mike Hichwa, talking about "Oracle APEX Past, Present and Future”. Of course everyone is curious what the APEX future might bring: Friendly URL’s, automated testing, more JSON, concurrent APEX versions, third party Oauth 2 authentication (think Facebook, Google), APEX app diff and more, a lot more, REST capabilities. And now we have to wait for APEX 5.2 … and that might take a while! 
After this keynote, the conference split up in three tracks. After the coffee break I returned to to big theatre where Geertjan Wielenga talked about "Finally Javas…

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!
