This illustration shows three Oracle databases with two stream paths flowing between them.

Both stream paths start with a capture process (component ID 1) at the first Oracle database that enqueues messages (component ID 2). From the queue (component ID 2), two propagation senders send the messages to the second Oracle database and third Oracle database.

The first stream path flows from a propagation sender (component ID 3) at the first Oracle database through components in the following way:

• The propagation sender (component ID 3) sends messages from the queue (component ID 2) to a propagation receiver (component ID 5) at the second Oracle database.

• A propagation receiver (component ID 5) at the second Oracle database enqueues messages received from the propagation sender (component ID 3) (component ID 6).

• An apply process (component ID 7) dequeues messages (component ID 6).

The second stream path flows from a propagation sender (component ID 4) at the first Oracle database through components in the following way:

• The propagation sender (component ID 4) sends messages from the queue (component ID 2) to a propagation receiver (component ID 8) at the third Oracle database.

• A propagation receiver (component ID 8) at the third Oracle database enqueues messages received from the propagation sender (component ID 4) (component ID 9).

• An apply process (component ID 10) dequeues messages (component ID 9).
