Description of the illustration xstrm084.eps
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
andpdb2.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, theoe.orders
table, and theoe.order_items
table. from thepdb1.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.
