Weekend Reading: Oracle DB 11.2 Upgrade

Working on getting to the 11.2 database patch set?  Well Tanel wants us to know about a slide deck from Oracle that has over 500 pages of information in it just about this!  Awesome reading material, and something to sink your teeth into (Halloween pun intended) over this weekend.  All that AND another document link which details the behavior changes from 8.0 to 11.2 (and I'd bet it'll be soon updated for 12c too).  Have fun!
