Illustration strep033.htm shows the details of the mult1.net Streams configuration, including the following mechanisms:

• One queue that is used by the capture process, propagations, and apply processes.

• A capture process that captures changes in the redo log and converts relevant changes into LCRs, which it enqueues into a queue. The capture process captures a change only if its tag is NULL.

• One apply process that applies changes from mult2.net and another apply process that applies changes from mult3.net. Both of these apply processes dequeue changes from the same queue. Any apply change from mult2.net and mult3.net has a tag of '00' in the redo log.

• One propagation to propagate locally captured LCRs to mult2.net and another propagation to propagate locally captured LCRs to mult3.net
