Deb recently bought a new kettle.
Now, a kettle used to simply boil water and turn itself off when it was done.
Not this thing.
It lights up as it boils and announces the fact that it’s finished with a melodious ping.
It’s got gauges and lights and switches.
I’ve decided that it’s probably a Dalek in disguise.
Like Daleks (or at least, the original Daleks), it can’t go up stairs – or if it can, it’s not advertising the fact.
Every morning, descending to the kitchen is filled with trepidation.
When will the Dalek tire of vaporizing innocent water molecules and move on to World Domination…
Doc-tor ! Doc-tor ! I feel like a ket-tle !
I wouldn’t be entirely surprised to find that, like most whizzy modern appliances, it runs on Java.
Which brings us, by a fairly circuitous route, to the topic at hand – SQLDeveloper.
Oracle’s latest incarnation of it’s IDE does indeed run on Java – the version 7 JDK to be precise.
In this post, I’ll go through the steps required on Mint to :
Install the Java 7 JDK
Install SQLDeveloper 4
Persuade SQLDeveloper 4 to play nicely with Java
Add SQLDeveloper to the Cinnamon Menu
The good news is that we can do all of this without the messy alien conversion of an rpm package to .deb format.
NOTE – I’ve followed these steps on Mint13, but they should be pretty much the same for any Debian Distro.
Anyway, without further ado…
The magic of the FA Cup. It’s one of those cliches that you are brought up to believe as an article of faith if you’re English.
It is supposed to refer to the glorious unpredictability in a knockout cup competition where there is no seeding.
In recent years, it’s become a lazy journalist’s phrase. An attempt to sensationalise a result that, usually, isn’t that surprising.
In this year’s fourth round, however, Non-league Luton Town went to Premier League Norwich and won, 1-0.
The first time in 24 years that a top-flight club has been knocked out by one outside of the Football League has taken it’s toll.
Simon, life-long Luton fan, now has some very achy face muscles as a result of walking around with a huge grin on his face for the last week.
At this point, I could try to relate this sporting miracle back to the Star Wars theme that’s been running through this series of posts on Oracle Licensing, but it’s a bit difficult.
Luton, plucky underdog rebels. Norwich City the Evil Empire…I just can’t really see it. Delia Smith as Palpatine with Chris Hughton as Darth Vader ? Somehow it just doesn’t seem to work.
Anyway, back to the license stuff. So far, we’ve looked at :
“You’re problem is you’re BBC”, a colleague remarked recently.
On further investigation, I found this not to be some reference to the British Broadcasting Corporation but rather that I had been “Born Before Computers”. Yes, I grew up – in computing terms at least – on the Command Line.
A number of things have changed since those dim and distant days.
Recently, I had a comment from Darryl claiming that chocolate bars had also been gradually reducing in size.
Damning photographic evidence of this scandal has recently come into my possession…

There’s more. My phone keeps insisting that I can’t spell and arbitrarily replacing words when I’m writing an SMS.
“You’re just the breast” took a bit of explaining to a rather skeptical Deb.
Having finally persuaded my phone that I really don’t require it’s assistance when composing a short missive, I have now turned my attention to SQLDeveloper. Continue reading →
SQLDeveloper 3.0 production has finally been released.
Like a kid on Christmas morning, I ripped off the wrapping paper and plunged straight into the installation on my Ubuntu laptop.
All was going according to plan…until I fired it up and found that it hadn’t imported my connections from SQLDeveloper 3.0 EA4 ( 22.214.171.124).
It seems that the production version has got a bit sniffy about it’s Early Adopter sibling although, oddly, it does still import any extensions you have installed.
Anyway, to save you the trouble of setting up all your connections again… Continue reading →
A couple of years ago, I wrote an application to reverse-engineer a CRUD matrix for tables in an Oracle database.
I’ve since used it quite a lot for impact analysis and have refined it a fair amount. I’m now happy enough with the new version to let it take it’s first steps into the wider world….where doubtless people will be able to find some of the bugs that I’ve missed.
At this point, if you’re wondering what a CRUD matrix is, you can have a look at the original post here. Continue reading →
My new year’s resolution that no alcohol will pass my lips is in no way connected to the fact that the only drink left in the house is half a bottle of cooking sherry that I’ve had for ages and really don’t like the look of right now.
As I’ve struggled through the hangover haze of a New Year’s Eve spent being corrupted by my better half, I’ve made a number of discoveries :
I now know why Belgian beer is only served in small glasses
the more you drink, the less it matters about the accuracy of your cocktail mixing skills
don’t try and install SQLDeveloper on Ubuntu if you’ve got a hangover
A colleague of mine (Martin, you know who you are), remarked the other week that he wasn’t overly interested in the contents of the blogosphere. He said that it usually put him in mind of the cartoon of the tag-cloud consisting solely of the word “me”. This got me to thinking, why do I do this ?
Let’s put my ego to one side for a moment ( pause to sounds of straining, followed by a dull thud). That was heavier than it looked.
One of the reasons for maintaining this blog is that I’ve got a quick reference to look at if I come across something I did a while ago and need a quick reminder of syntax etc. Also, my Mum likes to know what I’m up to.
The starting point for this entry was to attempt to drag together all the basic bits about Ref Cursors in PL/SQL – specifically, accessing them from within PL/SQL itself.
Whilst I was writing this, it was pointed out to me that SQLDeveloper doesn’t handle Ref Cursors quite as nicely as Toad. The specific issue was the difficulty in dumping the results into a grid, from whence it can be transferred to Open Office Spreadsheet ( or Excel).
For the most part, Ref Cursors are used to transfer data from the database to a web application. So, why would you need to start fiddling about with getting results back in PL/SQL ?
There are probably several answers to this question. However, for me, it’s mainly a case of having to trace problems raised in various support calls. Knowing what data results from each of the calls in a process usually helps a bit. Continue reading →
