Description of the illustration strms060.eps

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

The first stream path flows through components in the following way:

• A capture process (component ID 1) at the first Oracle database enqueues messages (component ID 2).

• A propagation sender (component ID 3) sends messages from the queue (component ID 2) to a propagation receiver (component ID 4) at the second Oracle database.

• A propagation receiver (component ID 4) at the second Oracle database enqueues messages received from the propagation sender (component ID 3) (component ID 5).

• An apply process (component ID 6) dequeues messages (component ID 5).

The second stream path flows through components in the following way:

• A capture process (component ID 7) at the second Oracle database enqueues messages (component ID 8).

• A propagation sender (component ID 9) sends messages from the queue (component ID 8) to a propagation receiver (component ID 10) at the first Oracle database.

• A propagation receiver (component ID 10) at the first Oracle database enqueues messages received from the propagation sender (component ID 9) (component ID 11).

• An apply process (component ID 12) dequeues messages (component ID 11).
