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. >>> >>> Operating System Rolling >>> Upgrades and Patches >> How?

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! >>> Online load balancing and >>> scale-up >> And that of course is possible with a single node? > > Simple, just move to a larger VM.

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... >>> Increases the benefit of >>> Oracle VM with the high >>> availability and scalability of >>> Oracle RAC >> How many sites out there are running production RAC dbs in a virtual >> environment?

No idea ... must be some strange inside reference to something.

I should've said sites rather than environments. I can only plead end-of-year workload, and not properly proofing a silly usenet post. jg -- @home.com is bogus. http://www.signonsandiego.com/news/2009/dec/31/internet-writer-to-challenge-tsa-subpoena-in-court/ |
