I’ve had my first play with 11gR2 today:
Nothing too unpredictable really.
I guess the most noticeable change is the new installer. I didn’t have an issue with the old installer, but a few friends from the Microsoft world had pointed out how dated it looked. The new is much cleaner, and although it will take some getting used to, I think it is a step in the right direction.
I’ve decided that I’m only going to do 64-bit installations from now on. I see little point doing the 32-bit installations, as I hope I will never work on one again. 🙂
