Parallel Development in Apex

Source: http://paulhammant.com/files/multi-branch.jpgMy current client has a large number of Apex applications, one of which is a doozy.

They always have a number of projects on the go with it, and they wanted us to develop two major revisions to it in (more...)

Random XDB authentication problems with Apex and EPG: problem solved? So it seems.

human readable URLs in Oracle APEX – Part 2

In the first part of this Blogpost Series we touched some fundamentals and finally listed some options. If you haven’t read it, yet, please do now before continuing here.

The last post ended with me saying I found a way for hrURLs that works with APEX Listener, mod_plsql and EPG.

hrURL – human readable URLs in Oracle APEX

Searching the APEX Forum for nice URLs is as old as Oracle APEX itself, so far without much luck. There is magic switch that forces APEX to create readable URLs.

As part of preparing my Presentation “Going Public” for Kscope 2014 in Seattle, I investigated the available methods on providing readable URLs and found some good ones.

You can check this public APEX website to see how good URLs can look like: www.click-click. (more...)

APEX Tree based on Pipelined Table Function

D-I-Y apex_mail_log maintenance and an Apex feature request
