It’s a Bank Holiday weekend here in the UK.
This is usually a time for doing odd-jobs as a distraction from watching the rain come down.
This time around, rather than subject you to another lament about the Great British Summer ( or lack thereof), I’m going to go through the steps needed to install APEX5 on Oracle 11gXE.
Now, I know that the documentation doesn’t mention Express Edition.
I also know that the instructions that Oracle do have for upgrading APEX on XE haven’t yet been updated to account for APEX5.
I know this because I’ve spent a wet Bank Holiday finding this stuff out the hard way so that (hopefully), you don’t have to.
What I’m going to cover here is :
I would say “let’s get cracking before the sun comes out”, but that would only give us until around the second week in July… Continue reading →
It is a strange time in the UK.
I’m not referring to England being 2-0 up after 2 tests in the Ashes (something that happens about as often as a Briton winnng the Men’s Singles at Wimbledon), nor the fact that a Briton has won the Tour de France for the second year running.
Stranger even than that is the bright yellow ball in the sky which has replaced the traditional warm rain of the British Summer.
This phenomenon has had a strange effect on the cat. Her animal instincts obviously alerted by the unfamiliar change in the climate, she currently spends almost all of her time out in the garden.
Unfortunately, she seems to have decided to treat said garden as something of a litter tray. This will necessitate something of a mine-sweeping exercise before I next mow the lawn.
It’s frustrating when you’re anxious to start something but then hit an unpleasant roadblock.
For example, you may have decided to have a play with that Oracle XE/Apex installation on your laptop that you haven’t used for a little while. However, when you come to connect, you realise that you can’t remember the password.
Health Warning – Before I go any further, I should point out that doing this is not something I’d recommend on anything other than a system that’s being used simply as a playground for you to experiment and which contains no sensitive data.
Guilty pleasures. For some, it’s a “diet” burger with “diet” fries, washed down with a “diet” shake. Others have a penchant for Kurt Geiger shoes. “I’m Welsh and I’m worth it”, they may well say. It may even be that Def Leppard track nestled in your playlist between Coldplay and Oasis.
In programming terms, APEX seems to fall into this category for me. On the one hand, it’s a declarative development environment. This means that, unless you’re very careful, the application you write for it is not going to be too portable to other front-end technologies. But, oh, it’s so nice to be able to bang out a bit of SQL and/or PL/SQL, click my mouse in the right place, and have a nice GUI application drop onto my browser.
If you’ve decided to try the latest and greatest APEX version on your XE installation, you’ll notice that the default Database Welcome Page disappears after the upgrade.
Rather than hunting around for it, I’ve decided to knock up something a bit better…well, different.
So, if you’d like to know how to get some interesting configuration information out of the database…or just want the entertainment value of watching me blunder about in APEX then read on… Continue reading →
