Oracle 12 Odds

The links from this page were put here to form a record of some of the things I've come across when playing with Oracle 12c. As the record is for my purposes, I probably don't explain much on any of the pages.

I have started putting some information on Wordpress, and what I put there should have a bit more explanation around it. You are welcome to get what you can from these pages,..,. just I'm not promising that it will be much!
