Home -> Community -> Mailing Lists -> Oracle-L -> Re: Master to Master Replication and availability
Greg,
One of my customers does, and has had at a time something like 10 or 15 replicated databases, using a 'hub-and-spokes' topology. They weren't using Oracle replication, but some in-house code, not flawless but by-and-large satisfactory for their needs. It isn't 'synchronous' replication proper (to me, the main advantage of replication is the shock-absorbance provided by queues) but near real-time across 3 continents (something like 4/5 seconds for a Paris to Tokyo roundtrip).
