Point-to-Point topology

With the Point-to-Point topology, each database generates a transfer package for one of two uses. The uses include a database to which information is to be sent or a database to which control of a CR is to be handed over.

For example, imagine three databases (A, B, and C) that want to replicate change request information between each other, and possibly hand over control. Using the Point-to-Point topology, database A can generate to B and C any change requests that it wants to either send, or hand over control. Similarly, database B might generate change requests to A and C, and database C might generate change requests to A and B. When only two or three databases are involved, this methodology is the simplest DCM replication topology.
