RE: RAC (Real Application Clusters)
is blowing in California and it's not from the forest fires. One last item. Don't look for RAC to fix your application problems. If your application already has problems RAC won't fix that problem and if your application is not designed to scale then RAC will provide high availability but not scalibility.

RE: RAC (Real Application Clusters)
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.

RE: RAC (Real Application Clusters)
RAC isn't meant to be cheap. It is a fault-tolerant technology. You cannot buy a Ferrari or Aston-Martin for $15,000 with only 2.5% APR. As a matter of fact, when you are buying a red Ferrari, you are probably not even going to mention APR. That is a difference between Ford Focus or Dodge Neon and a Ferrari. On the other hand, Neon or Focus probably do have better gas mileage. -Original Message- From: DENNIS WILLIAMS [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 11:44 AM To: Multiple recipients of list ORACLE-L Subject: RE: RAC (Real Application Clusters) Glenn - I have a question you could ask.

RE: RAC (Real Application Clusters)
Yes, I concur. RAC might be positioned as a cluster of cheap Intel/Linux servers but a true cluster isn't really cheap. On Compaq Tru64 Cluster, we are going for a Memory Channel Interconnect which, I understand, is even more expensive than Gigabit. hemant At 07:43 AM 26-09-02 -0800, you wrote: Glenn - I have a question you could ask.

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. -Original Message- Sent: Thursday, September 26, 2002 11:14 AM To: Multiple recipients of list ORACLE-L Dennis, True, a 2/3 node clusters ain't that cheap.

You cannot buy a Ferrari or Aston-Martin for $15,000 with only 2.5% APR. As a matter of fact, when you are buying a red Ferrari, you are probably not even going to mention APR. That is a difference between Ford Focus or Dodge Neon and a Ferrari. On the other hand, Neon or Focus probably do have better gas mileage. -Original Message- From: DENNIS WILLIAMS [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 11:44 AM To: Multiple recipients of list ORACLE-L Subject: RE: RAC (Real Application Clusters) Glenn - I have a question you could ask.
