Home -> Community -> Mailing Lists -> Oracle-L -> RE: RAC (Real Application Clusters)
To which I would add... downtime and losing data can be very expensive so
given the alternative, if you need fault tolerance and scalability then
maybe it is cheap by comparison.

Dennis,
True, a 2/3 node clusters ain't that cheap. But to achieve high
availability
the other choice is to buy a high end server like Sun E10k or the newer
ones. And I think the 2/3 node clusters are cheap compare to those big
iron boxes and you get a very good availability and scalability from
clusters.
I think that's the selling point of RAC. You can cluster bunch of cheaper
Intel based machines running Linux cluster and run RAC on it.

Glenn - I have a question you could ask. Oracle talks about how RAC will
allow Oracle to make better use of cheap computers. To me the weak point is
how much bandwidth you have between the nodes. If you have a gigabit fiber
optic connection between the nodes, it might work well, but suppose you have
a shared LAN? To me, RAC would work quite nicely in a clustered server, but
then we've strolled away from cheap, haven't we? This point is keeping my
hardware people from buying into the concept.

I am visiting Oracle next week and will be getting a dog-and-pony show on Oracle 9i and RAC (Real Application Clusters). Does anyone have any experience or comments on this product/technology? Can you suggest some burning questions I can pose to Oracle when we get the demos? This is a technical overview and we will be seeing conversions (Apps and non-Apps environments) as well as failure scenarios.
Any advice/comments are welcome. Thanks.
