Yeah, but they don't tell anyone that. It's simply stated that one-node RAC can do all that. It can't. Not by itself.

Look, when RAC first came out I asked Grant Ronald very specifically: exactly how does one address upgrades and patches in a RAC setup?
His "reassuring" answer was: "it's all automatic". Alarm bells straight up, everytime someone from Oracle says: "it's all automatic"!
That was with 9i, nearly 10 years ago! Nowadays, they still can't do it... I'll bet anything that Omotion only works in one system: the one they use for demos!

Oh yeah! LOL!

But the really sad thing is these marketing nongs make claims like that without
even checking their own product range!
Talk about absolutely, totally, *no clue*!...
Cripes, half the add-on product range of the last two years has been on Linux only! For a long time the best advantage of Oracle was their portability and availability in a wide range of platforms, now they are finally shooting themselves in the foot with their strongest (only?) advantage...
