It was written for Oracle 7.2 but it's incredible to see how much the basic things are still relevant today. Of course, there is  a reason for that: the mecanisms of recovery are critical and must be stable.

Friday Philosophy – At What Point Can You Claim a Skill?

I’ve just installed Oracle 12C on my laptop {I know, why only now?}. I went for the option to have a Container database with a pluggable database within it. {It is easy and free to install Oracle on your own home machine – so long as it is for personal use only and you are singed up to OTN (which is also free) }.
