All too often, I see people asking questions about backup strategies they should employ for their databases. It never seems to fail, every question of this sort that I have come across in a variety of forums never once includes their recovery requirements.

Background Processes
I swear that as I get further and further along in my Oracle career, I have a harder and harder time keeping up with Oracle’s background processes. I’d like to chalk this up to getting older, but after digging into it, I’m pretty sure its just Oracle’s explosion of background processes in 11g that is …
