It’s that time of year again: Conference Season! There’s a few conferences that fall in the 1st few months of the year that I try to present at each year, and this year is no different. Here’s where I’ll be presenting at over the next few months:
RMOUG - Denver, CO - February 5th - 7th At RMOUG this year, I’ll be co-presenting a new session called “Creating a Business UI in APEX” with Jorge (more...)
Now that APEX 5.0 EA is out, it's time to do a deep dive in the new features of this early adopter (EA) release.
Overall this new version of Oracle Application Express tries to put even more power and speed in the development. The UI is made simpler and cleaner with a fresher look and feel. Not every part of APEX got an overhaul in EA1, it remains to be seen if in EA2 (more...)
One of the first things I checked in APEX 5.0 EA was the region positioning of the sub regions. I was positively surprised to see that I can now position the regions next to each other as well. In earlier versions the only option was underneath. Having this possibility it will be much easier to create complex forms where you need to take care of positioning multiple items in more than one column. At (more...)
This is definitely the best APEX version ever. I just tested it and it took less than a couple of minutes to get used to it. You know how hard it is to accept major changes. This time it was easy. The changes made in the builder will for sure increase the productivity although this was never a weakness of APEX. There are of course some things missing (or I just couldn't find them) like (more...)
Suddenly a big thunder rolled through the APEX community -> Version 5.0 has arrived in an early adopter version, as published on Joel Kallmans Blog (as usual on a friday, late night over here in europe).
Over the past 10-15 month we saw numerous presentations of what we can expect in APEX 5, and many of us had our own ideas.
As soon as I got word through twitter I applied for a workspace (more...)
Requesting a workspace is not working yet at the time of writing this post, but I expect it can be opened every moment now.
APEX 5.0 carries many new features, one of the biggest is the new Page Designer which should increase developer productivity even more. David Peake recorded some videos, here's the APEX 5.0 Page Designer Overview:
I created a small mobile APEX app for my football team where they can upload pictures to the app.
Sometimes saving the picture worked, sometimes it didn't. If it didn't work I hit the following error: "Post too large". It turned out that my Max Post Size in Configurations - server-config - Network Config - Network Listeners - http-listener-1 under HTTP was set too small.
While I was setting up a demo the other day, I ran into the following issue: My main start page contains a list of customers and that list is created by a call to a (remote) web service. Due to the nature of this service, it takes a few seconds to get a result back - not very slow but slow enough to annoy me. So I looked at ways of caching the web service (more...)
In January 2004, Oracle Database 10g was released. And bundled with the Oracle 10g Database distribution was an additional disc called the Companion CD, which included both Oracle HTTP Server, mod_plsql and this new tool called Oracle HTML DB 1.5. This was the date of the first officially distributed and supported software from Oracle which has grown into today's Oracle Application Express.
In case you use partial page refresh inside your reports you may have encountered an issue that you always stay on the bottom of the page even after the refresh of the report. One of my customer marked this as a bug and meant that after the refresh the display position should be at the beginning of the report.
Seems complicated but worked out to be really easy: Add a dynamic action: After refresh (more...)
Außerdem plant die Community nun schon seit einiger Zeit an einem APEX Stammtisch in Frankfurt. Wer Interesse hat kann sich hier anmelden: http://doodle.com/b9uqef2338itkgkv Mit etwas Glück könnte der Termin im Anschluss des DOAG Treffens stattfinden. :D
Schon etwas weiter in der Zukunft (Mai 2014) liegt der nächste Best Practices Kurs von (more...)
If you’re interested in developing Mobile Web Apps on the Oracle Database – and if you’re following my Blog, chances are that you are – then here’s a great opportunity to get up to speed on the latest trends and learn how you can quickly and easily develop your own mobile web apps and extend your existing APEX apps for mobile use: attend my upcoming free ODTUG Webinar on February 20th:
Our next training will be held in Bensheim on 26th of May 2014. You can find the details here.
Die Erfolgreiche Trainingserie geht auch in diesem Jahr weiter. Dietmar Aust und ich organisieren ein weiteres Best Practice Training am 26.05.2014 in Bensheim. Diesmal findet das Training auf der Basis von APEX 4.2 statt. Nutzen Sie die Möglichkeit von Experten zu lernen und melden Sie sich an. Einen Link zu der Anmeldeseite finden (more...)
This example seems still to be interesting to some people in the community. The number of requests and questions I am getting regarding it forced me to update it. Now the rendering is using an application process instead of a public procedure - using public procedures in XE is somewhat tricky.
"Learn something new about Oracle almost every day"
"Learn a new technology outside the comfortable realm of Oracle Database".
Resolutions I try to follow myself every year...
I love to try and integrate different technologies with Oracle APEX. Looking back at the last two years, just from the Oracle stack alone, in 2012 I played around integrating APEX with E-Business (more...)
In this example you can see how easy it is to preserve report pagination after PPR. With a little jquery coding you can attach a function to the pagination request and this way "document" where the pagination goes. After a report refresh you may read those values and paginate back (more...)
