This illustration shows a sample XStream Out configuration with two outbound servers. The illustration shows two client applications and an Oracle database. The Oracle database includes the following components:
A redo log that records the changes for the hr schema, the oe.orders table, and the oe.order_items table
A capture process that captures DML and DDL changes to the hr schema, the oe.orders table, and the oe.order_items table. The capture process converts the changes to logical change records (LCRs) and enqueues the LCRs.
A queue that stores the LCRs that were captured by the capture process
An outbound server named xout that dequeues LCRs from the queue. One client application receives the dequeued LCRs.
An outbound server named xout2 that dequeues LCRs from the queue. A second client application receives the dequeued LCRs.
