Hi Giovanni,
My own experience has been that it is fairly stable
once up and running, but once something goes wrong, a
bear to get right(trigger based replication in 9.2).
If you want to implent replication anyway, choose
streams based replication since it is much easier to
manage.
So I'd also recommend that you stay away from
replication as a failover solution. Instead, I think
that DataGuard is a better solution. It is also
designed to work with 9i RAC.
