Oracle-L: RE: clustering

Active/active = RAC

Active/Passive = Traditional Sun and Veritas clustering

Basically, in RAC both nodes are up servicing queries and if a node fails, the other one takes care of recovering the other one's transactions.

In traditional active-passive clustering, one node sits there twiddling its thumbs until the first one fails, at which point it springs into action and takes over for the failed node.

Does that help?
