This year it's called a "Professional Learning Event" instead of a conference and the program reflects it - plenty of hands on workshops mixed in with normal sessions. Considering it's (more...)
It will be the same session I did for AUSOUG back in July, which is lucky since it's 6am for us Perth locals. It's a close look at the Oracle APEX 5 Page Designer, and what it means to you as an APEX developer.

Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.
The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)
I love Interactive Reports, they make it easy to deliver a lot of power to users for very little development effort. However, with that power comes some complexity for building certain features not available in the base Apex toolset.
I had an IR with a fairly costly and complex query behind it, linked to another screen to view the details for a record. The (more...)
This article describes how to standardize your JDeveloper Patching as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the patching with examples for windows.
All what you need is the patch file for your platform (e.g. p19591087_121300_Generic.zip for JDEVADF SECURITY (more...)
A couple of very, very basic observations on getting going with 12c Inmemory in a multitenant database.
1. When trying to set inmemory_size within a PDB when inmemory_size is 0 in the CDB
ORA-02096: specified initialization parameter is not modifiable with this option
SQL> alter session set container = cdb$root; Session altered. SQL> select value from v$parameter where name = 'inmemory_size'; VALUE -------------------------------------------------------------------------------- 0 SQL> alter session set container = orcl; Session altered. SQL> alter (more...)

Oracle Database 12c introduces a
SEARCH_CONDITION_VC column to the
USER_CONSTRAINTS views. The
SEARCH_CONDITION_VC column is a
VARCHAR2 data type equivalent to the search condition in the
LONG data type
SEARCH_CONDITION column. Unfortunately, Oracle Database 11g and earlier versions requires you to convert the
LONG data type to a
VARCHAR2 for the equivalent behavior. This post provides you with a function to help you do that in (more...)

Same concept, different theme. All the SQL statements below are clues to the English spelling of countries.

- Working programmatically with bindings
- Getting the binding from a component
- Working with dynamic bindings
- Creating a binding programmatically
One of the most wonderful things of Oracle Open World are the Demo-Grounds. When you want to learn more about a certain feature, this is the place to go to. The actual developers and product managers are there to answer your questions and more!
In a previous blog I had written about Temporal Validity in Oracle 12c and whether it would be possible to have multiple validity periods on one table. You can read that (more...)
Trouble is, sometimes it's hard to decide how to structure your packages - particularly in an APEX project. Over at the PL/SQL Challenge website run by Steven Feuerstein and friends there is a page dedicated to roundtable discussions.
I submitted my question not so long ago and hope to get some interesting responses. Why don't you give the site a visit and contribute? The discussions usually last for about (more...)
I was just in Stockholm visiting a customer, and I noticed a new feature in my Volvo rental car: You could set the cruise control to a speed limit.
(apologies for the blurry picture, it was taken by my Narrative shirt pocket camera)
You drive the car as you would normally do, but when you approach the set speed, the car does not go any faster when you press the accelerator further. Unless you kick (more...)
