APEX Community Sample Applications

There are a bunch of sample APEX applications out there built by developers (typically with blogs) that are darn useful, but so far I haven't seen a useful central repository.

So I've started one here with a very basic form/report:

Running two oracle installations from the same terminal

Two posts from me on the same day. The other one about Datapatch is about a brand new utility in 12c and is probably new to most people. This post caused mixed reactions when I mentioned it at work last week. Some people laughed at my naivety in not knowing about it, others took the same view as me and were interested to hear about it as it may prove useful one day.

Issue with Datapatch – AKA SQL Patching Tool after cloning a database

There have been a few changes in the way patches are managed and monitored in 12c and whilst looking at this I found a potential problem that might occur when you clone or copy databases around, or even build them from a template file.

Firstly when you apply a PSU and run an opatch lsinventory command you now see a description of the patch rather than just a patch number – here showing that PSU 1 has been applied. This came in at 11.2.0.3 and in my opinion is really helpful.

Oracle ACEs at OUG Ireland 2015

The annual Oracle User Group in Ireland Conference will be on Thursday 19th March. This year the conference will be held in the Croke Park conference centre. This conference centre is only a short taxi ride from Dublin Airport and Dublin City Centre. If you are planning a hotel stay for the conference I would recommend staying in a hotel in the city centre and get a taxi to/from the conference venue.

2014 Annual SQL Championship

Steven Feuerstein runs a great site at PL/SQL Challenge that is just another way for developers to stay up to date with their knowledge of PL/SQL, SQL and database design with a bit of fun.

PL/SQL championships are held quarterly, but the less frequent SQL and Database Design quizzes are currently held annually. Thanks to persistence and maybe a bit of experience, I was eligible to compete in both.

Twitter as a work tool

Scott Spendolini conducted a little experiment last week, then Jeff Smith & Kellyn Pot'Vin whipped up a little slideshow on the topic.

I thought I'd chime in after some recent experiences were helped along by the use of Twitter, a tool it seems many are underutilising.
