Telling people they probably don't need it might lead some to violate
their license.

That is true, but the people running RAC with standard edition definitely
do not need RAC.

I completely disagree. Why this attitude from both you, and to some
extent Oracle, that people using SE don't need high availability? Is
this some kind of anti-SE prejudice? You don't need MAA unless you
have deep pockets?

Just because someone doesn't need the full feature set of EE does
not mean they don't need to eliminate the server as a single point
of failure (or a DR site).

I know a number of organizations that use SE RAC clusters to support
their Grid Control OMR. Can you think of a single reason why they
would want to go to EE? A single reason why they wouldn't want to
invest a bit of effort in making sure the Grid is always up?

I sure can't.

I agree with Daniel, i'm working for a ISV, we can ask our clients to
buy EE licenses, we sometimes offer
RAC with standard edition, only two nodes, we have never experimented
really high avalability, when we
hava had problems was with database itself and Oracle bugs, not with a
single machine failure. But
i think that same would have appened if we was using Enterprise
Editition two nodes RAC, but
having spent the triple of money of Oracle licenses. We have a
customer with 400 users, we have
no tests of single instance, but another customer with 9iR2 RAC on AIX
(so EE) with hardware
three years older have had performance problems, also with EE.
So i think that RAC with Standard Edition may be an interesting
solution.
