This illustration shows a sample XStream Out configuration that can be configured using the CREATE_OUTBOUND procedure. The illustration shows a client application 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. The client application receives the dequeued LCRs.
