"On the same platform" at which point ?

same box,
same OS,
same patching scheme,
same magnetic sticker forgotten by a malicious DBA ?

My post wasn't crap, it was also sent to make people react.

I may have made a mistake saying that stand by DB could be the solution. Anyway I can't imagine such an efficient solution to implement high availability to be restricted by
hardware or OS considerations.

Sybrand, if you have time to answer me, I'd like to know more about that.
