Assuming that you mean Oracle Real Application Cluster (the Grid is more, 
right?) I wonder if this technology technically still counts as replication. 
AFAIK they do not replicate data but share a common data pool among different 
servers. You still have communication overhead but you write a tuple only 
once for all servers involved. Takes away a lot of overhead on a system 
that's heavily written too.
