Description of the illustration xstrm078.eps

The illustration shows three Oracle databases. In one Oracle database, the redo log records changes to database objects. The redo data is sent to the second Oracle database. At the second Oracle database, the changes are captured by a capture process from the source redo data and enqueued as LCRs into a queue. The LCRs are propagated to a queue in the third Oracle database. In the third Oracle database, an outbound server dequeues the LCRs from the queue, and a client application receives the LCRs.
