There are perhaps two maybe three third party vendors out there who
will claim to be able to help you out here. For older Oracle versions
(8 and older) some may use triggers for replication but starting with
Oracle 9 they all replicate transactions by reading the Oracle
redo/transaction log. The fellow who did most of the designing of these
logs (and transportable tablespaces) for the last 10 years is named
Alok Pareek. And he is now with GoldenGate Software working on their
replication product.
