Oracle acronym madness

I delivered a private RAC training class a few weeks ago and one of the things I was asked during introductions was to limit the amount of weird acronyms to a minumum. “OK”, I said and thought, there are maybe a handful of three-letter abbreviations that I’ll be using but they should not be more than a dozen. To check on myself, I made a point of writing down most of the acronyms I used together with their meaning. I was more than surprised to have collected more than 50 of these after just two days. Crazy.

Anyway, here is the list, maybe the translations will be helpful to those poor souls that are getting in contact with Oracle database technology for the first time and need to figure out WTH everyone else is talking about.
