Most production databases at USPTO are high availability (some are two nodes RAC, DATAGUARD… primary has two standbys which are converted into snapshot standby for application/performance testing. ORACLE GOLDEN GATE is our replication tool: (one-way replication/bi-directional replication) we are also replicating (extracting) schemas from a standby (and archived log area) which has to be in an ACTIVE role for this to occur.
