This illustration shows an Oracle Streams replication environment with a capture database and three destination databases. These databases are:

• The capture database has a capture process and a queue. The capture process enqueues captured LCRs into the queue. Propagation B at the capture database propagates LCRs to a queue at destination database B. Propagation C at the capture database propagates LCRs to a queue at destination database C.

  The capture database also contains a cloned capture process and a cloned queue. The cloned capture process is disabled. Cloned propagation A at the capture database is configured to propagate LCRs to a queue at destination database A when destination database A is up and the cloned capture process is enabled.

• Destination database A contains a queue that accepts LCRs from propagation A. This database also contains an apply process that dequeues LCRs from the queue.

• Destination database B contains a queue that accepts LCRs from propagation B. This database also contains an apply process that dequeues LCRs from the queue.

• Destination database C contains a queue that accepts LCRs from propagation C. This database also contains an apply process that dequeues LCRs from the queue.
