Hi
I am trying to understand the difference between 11gR2 RAC on one node and Cold
failover cluster .
The OTN whitepaper on cold failover cluster by Philip Newlan says that
clusterware can be used to protect a single instance oracle database.
This implies there is no additional liscensing costs if we have already brought
Oracle EE .
But the paper also adds a warning that oracle will not support cold failover
cluster so i am in a kind of dilemma.
On the other hand RAC on one node is a extra cost option as i understand it on
top of EE.
My question then is
a)Is my understanding above correct
b)Anybody out there using cold failover cluster.
