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.
