Re: Real World Experience of Oracle RAC and its ability to Scale

Synonym for typical ... regular.

What statistics can you show give evidence that RAC is typically deployed with more than 4 nodes? Possibly oracle has that information ... let's see you dig something up that we can authenticate. Proving a statement ... Tom Kyte does that regularly. So does Mr. Lewis. Other people just make up stuff.

Maybe it's just an english language thing. Seeing 8+ node clusters doesn't mean they are in the majority or even close ... which would meet the definition of typical.

The rest of what Mr. Morgan said appears correct except for the possibly wild speculation about block contention.

Personally I would recommend vendor references that might include visits to current customers and on-site demonstrations with current customers of the application vendor application running in production. Have them explain their recommended architecture and pro's/con's ... and keep drilling for detail.

Maybe it's just a lack of information or not enough information but something doesn't sound right so far. Received on Tue Apr 19 2005 - 19:50:53 CDT
