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 CDB. The Oracle CDB includes the following components:
The root container of the CDB
The PDBs pdb1.example.com and pdb2.example.com
A redo log that records the changes made to objects in the PDBs.
A capture process that captures DML and DDL changes to the hr schema, the oe.orders table, and the oe.order_items table. from the pdb1.example.com PDB. 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.
