Disclaimer: I’m not posting to make me look better, we’ve all written code that we’re later ashamed of, and I’m no different!
This is some code from a system I was maintaining some time ago. I’ve kept it since then because it illustrates a number of things NOT to do:
FUNCTION password_is_valid (in_password IN VARCHAR2) -- do NOT copy this code!!! ... RETURN VARCHAR2 IS l_valid VARCHAR2(1); l_sql VARCHAR2(32000); CURSOR cur_rules IS SELECT REPLACE(sql_expression ,'#PASSWORD#' ,'''' (more...)
This article describes how to standardize your JDeveloper Installation as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the installation with examples for windows.
In this version the Oracle Universal Installer allows the silent installation of JDeveloper. All what you need is the installer file for your platform (e.g. jdev_suite_121300_win64.exe) and a response file. You (more...)
From now on I will create a series of lessons to implement the knowledge of the ADF Architecture Course from Oracle ADF product management. Here you can find the videos and the presentations. This post will be the index of this lessons, so bookmark it for further use!

Now that the chaos of Oracle OpenWorld and the craziness of Kscope15 abstract submissions are behind us, it’s time to get into the nitty gritty of where your Enterprise systems are headed. Mobile development plans are at the forefront of everyone’s minds right now, and if it’s not on your agenda then it’s time to get to work!
The statistics of mobile adoption are STAGGERING; Gartner says that 40% of the workforce (more...)

What happens when iPhoto doesn’t export movies? One of two things, you re-install iPhoto and risk losing the movies and photos; or you drop down to the Terminal level and move the files manually before re-installing iPhoto.
Option one is easy, you open iPhoto, choose File from menu, and Export… from the File menu list. When you get to the dialog, change it Kind value to original. If everything is working, you should be (more...)
You all know that when you grant SELECT on a table to a user, they can do a SELECT FOR UPDATE, locking records in the table and preventing other updates or deletes. [Some client tools may do that in the background. ]
Well finally Oracle (more...)
Don’t you hate those nagging issues where you attempt a few fixes in vain, waste hours of your life, and then suddenly the issue just resolves itself? What’s worse than an issue that won’t go away is one that just resolves itself and you don’t know why. You don’t know if it is just hiding, waiting to reappear at some inconvenient time later (e.g. when the app goes live in Production).
I added the (more...)
Another Oracle OpenWorld is behind us (when did it become October?) and as usual, it was fun to catch up with the members of my Oracle developer community, my ODTUG buddies and fellow ACEs. Cloud was definitely the hot topic on everyone’s mind this year, especially because Oracle announced their upcoming Oracle Mobile Cloud Services and released their Oracle Developer Cloud Service to production a few weeks before the (more...)
I missed most of the total but enjoyed the crescent of the partial eclipse re-emerging. It's amazing how distinct the shadow leading to the penumbra.
My friend said there will be some good shots in tomorrow's paper. I laughed and said here in the 21st (more...)
It’s that wonderful time of year again – no, not talking about springtime, when I’m stalked by airborne grass pollens causing me to choke and gag all day. The sound of a lawnmower is enough to elicit a sneezing fit – and in Aussie springtime, that’s most weekends. (I’m so glad my wife does the mowing at our place, usually while I’m at work. My son is now old enough to do the mowing – (more...)
I think, it is as important as ever to follow best practices for server-side development. There are lots of options that could get the job done "now", but very few that would survive for months/years. Also, there is a constant pressure from various "alternative" solutions to (more...)
