Are you sure that no way to implement a generic aproach on the backend? What does specification say? Does Oracle 10g have a core implementation of replication (cluster)?

And, as I say every single time this comes up, Oracle's and IBM's and
MS's and everybody else's replication systems are _also_ add ons.  If
you don't believe me, look at the license costs.  You can get a
system without it enabled, which means (by definition) it's a modular
extension.
