Oracle replication is not performed via redo logs per say. The Standyby database option gets in this area a little bit. Oracle can support ASYNC replication using other Queues. Take a look at the Replication Manager. Contact your local Sales Consultant with the Sales team that works with your account. Anyway... using Async replication, you can store and forward transactions needing replication and control many aspects of the replication process. Synchronous replication is also supported.
