RAC - Interconnect traffic
214596May 9 2008 — edited Jun 24 2008In the client place the architecture team wants to implement a a node RAC cluster on Sun Solaris on Oracle 10g. But in order to minimize the interconnect traffic they want applications to connect only to one node and the other node will provide fail over capability.
Though this can be achieved with less complexity thru physical standby, theoretically if in a 2 node RAC cluster if we just use one node will it eliminate interconnect traffic?
I guess that there will not be any requests from the second node for blocks held by the first node so no transfer of blocks over interconnect will take place. But still the second node has to know about the blocks held by the first node in order to recover in case the first node crashes(cache fusion?). Right?
