Active/active =3D RAC
 
Active/Passive =3D Traditional Sun and  Veritas=20 clustering
 
Basically, in RAC both nodes are up servicing queries and if a = node=20 fails, the other one takes care of recovering the other one's=20 transactions. 
 
In=20 traditional active-passive clustering, one node sits there twiddling its = thumbs=20 until the first one fails, at which point it springs into action and = takes over=20 for the failed node. 
 
Does=20 that help?

Hi Guys ,
I am new to this clustering concept. = Just trying=20 to understand few basics . Need ur help .
 
what is differece between oracle = running on sun=20 /hp cluster with 2 nodes and oracle = with RAC=20 running on 2 nodes ? 
 
thanks,
