When I started writing this post, it was going to be about something else.
This happens occasionally, I have an idea in my head and set to work.
Then I do some research – don’t look so surprised, I do look at the docs occasionally – and, as in this case, I find out that there’s rather more to the topic at hand than I first thought.
What follows is a re-visiting of some of the tools available in Oracle to help with error logging.
It includes stuff that either I’d forgotten or had never considered about some fairly common functions.
Before I dive in, I’d just like to say thanks to William Robertson, who first pointed out to me the similarity between PL/SQL error logging and Quantum Theory. If you’re still unclear of the connection between the two then consider, if you will, the Schrodinger’s Cat Thought Experiment.
It involves locking a cat in a box and possibly poisoning it.
Schrodinger postulates that the cat is both alive and dead…until you open the box to check.
The conclusions we can draw from this experiment are :
- According to Quantum Theory, the act of observation changes the nature of the thing being observed
- Schrodinger wasn’t a Cat person
Before going any further, I should point out that most of the stuff I know about Physics comes from watching Star Trek.
Moving on, I now invite you to consider…
