I have to import a set of XML files from time to time. Most of those XML files can be imported with out any problems. But at least one file includes a special character U+0016 which occurs randomly some where inside the file.
When I try to import that file I get this ORA- error message:ORA-31011: XML-Parsing nicht erfolgreichORA-19202: Fehler bei XML-VerarbeitungLPX-00217: Ungültiges Zeichen 22 (U+0016)Error at line 39409 aufgetretenMehr »
Quick note: I finally managed to get the APEX Developer Addon signed by Mozilla and therefor working again in Firefox 43 upwards.
Please re-download and install, version of the Addon in Firefox is now 126.96.36.199. No changes for Chrome.
Apologies for the inconvenience and thanks for all those mails I got.
Last year was very eventful at FOEX, which kept me occupied and kept me from blogging. Thankfully I managed to attend a few conferences and stay in touch with the community through Twitter and Slack on apex.world.
FOEX is growing a lot and needed a new website design, so we had a brainstorming meeting and decided to again build it in APEX.
Last week we finally decided everything for the website was ready (more...)
The last part of my APEX 5 migrations series:- APEX 5 Migration - Part 1 - Requirements and Installation - APEX 5 Migration - Part 2 - Common application issues after the migration
This part is about the best and hardest migration:The Universal Theme migration (UT)!
Most of the developers love the new theme and its functionality but what makes it so different to the old ones? What is the value of (more...)
It's conference season! That means time to start looking at flights and hotels and ensuring that while I'm on the road, my wife is not at work (no easy task). In addition to many of the conferences that I've been presenting at for years, I have a couple of new additions to the list.
Here it is:RMOUG

One of the larger conferences, the year usually starts out in Denver for me, (more...)
Why would you need an "auto login"? Can't it be configured in APEX?
In APEX you have a setting to configure the maximum session length. But this setting only lasts a certain time (12 hours as most).
The setting can be found under Supporting Objects > Security Attributes > Session Management:
But in some use cases you don't want the application to log out and to manually re-login again.An "auto login" can come in (more...)
Last night (January 6, 2016) we had our first-in-2016 APEX Meetup meeting in Columbus, Ohio, USA
. For being on short notice, we had a nice turnout
, and I was able to distribute the new apex.world stickers. I was most impressed that a gentleman (by the name of Shannon) drove down from Cleveland, Ohio - almost 2 hours drive each way. He's been using APEX for all of two weeks, was using it with (more...)
Die Deutsche Bahn
ist auf der Suche nach einem APEX Entwickler.
Aktuell bin ich durch meine selbstständige Tätigkeit selbst vor Ort und meine Eindrücke möchte ich mal nach außen tragen, damit ihr seht wie die Bahn auch sein kann.Mich persönlich beeindrucken nicht die offensichtlichen Dinge vor Ort:
- Die Stadt: Frankfurt
- Die Firma: DB Systel (IT Dienstleister der Deutschen Bahn)
- Der Tower: Dein Arbeitsplatz ist an einer der höchsten Stellen in Deutschland (more...)
, from the Oracle Database Insider Newsletter
, asked a number of us in the Database division at Oracle to share our New Year's resolutions for 2016. And while I'm a bit reluctant to share this somewhat personal information, I like the fact that publicizing these resolutions may force me to remain a bit more focused on these goals. So here goes...my resolutions for 2016:
- Attend an Oracle Real World Performance Training class. (more...)
This small example
is showing how powerful jQuery is and how easy it is to use it in APEX. In this case
, I needed to correct the oracle formatting, which adds blanks to the name of the day prior to comma. Probably oracle RPAD's the day names to the longest (Wednesday). Those are showing in APEX as one blank - see the left column. The only good way to go around that annoying side (more...)
In meinem letzten Blogpost für dieses Jahr, möchte ich noch einmal kurz auf alle Highlights in 2015 eingehen. Ich wünsche viel Spaß beim Revue passieren lassen! :)
Als ich das Vortragsprogramm der APEX CONNECT 2016
gelesen habe, musste ich mich doch kurz wundern...Mehr »
This time I will tell you more about the most common problems in your APEX applications after an upgrade to APEX 5.
You will find the most migration bugs in following situations:
Ich hatte vor kurzem die Aufgabe erhalten eine Bitliste auf Basis eines Monats zu generieren.
Bedeutet, ich habe einen String mit 31 Zeichen der je Zeichen den Zustand 1 oder 0 einnehmen kann.
- 1 steht für aktiv
- 0 steht für inaktiv
Um dies anhand eines verständlichen Beispiels zu verifizieren, habe ich mir eine Dienstplan-Tabelle ausgedacht.Mehr »
During this year I have done several APEX 5 migrations and I held three lectures on the topic.
Unfortunately it only reached out in Germany, however the content would contribute to simplifying the work for everyone. So I decided to blog it. I will cover this topic in three different posts:
- Requirements and Installation
- Common issues after the migration
- Universal Theme migration
I start with the requirements and installation of APEX 5. (more...)
Just created a new feature request for APEX at https://apex.oracle.com/pls/apex/f?p=55447:19:::NO:19:P19_ID:50481528500531591330407043519019274105
… Extend Interactive Report API - Get IR Query. The feature request is abut the following:
"This API should deliver a couple of different SQL statements for an interactive report. There are several possible requirements I can think of:
1. IR query including visible columns and filter values - actual SQL for the user session,
2. IR query including all columns and (more...)
When the APEX Gaming Competition 2015
was announced by Vincent Morneau
at the ODTUG Kscope15 conference
this past year, I was very suspect. I've seen many contests over the years that always seemed to have very few participants, and only one or two people would really put forth effort. Why would this "Gaming Competition" be any different? Who has time for games, right? Well...I could not have been more wrong.
I was (more...)

After I looked through the chart types supported by the new Oracle JET framework
I asked myself if we need other chart plugins like D3JS or RaphaelJS in future APEX releases anymore?
The answer is: Yes in special cases.My supposition is that we can use all available JET charts in one of the next versions of Oracle APEX.
Now I will describe the "special case" with two examples where other chart frameworks still make sense:Mehr »
If you've been using APEX long enough, you've probably used a PL/SQL Region to render some sort of HTML that the APEX built-in components simply can't handle. Perhaps a complex chart or region that has a lot of custom content and/or layout. While best practices may be to use an APEX component, or if not, build a plugin, we all know that sometimes reality doesn't give us that kind of time or flexibility.
While the (more...)
