Replication Process Configuration

After you determine your replication scheme, you need to develop a replication process that is both reliable and flexible enough to address your business requirements. Figure 11–2 shows an example of a replication process configuration, based on the concepts described previously in this section.


Figure 11–2: Example Replication Configuration

Figure 11–2 represents a replication process between a site database on the left (1) where transactions are shown originating, and the master database on the right (2) where the transactions are replicated and propagated to all sites. In an actual scheme, more than two sites might share the functions illustrated.

The large arrows between the boxed items represent the process flow beginning with the data transaction on the left, and continuing through the replication process on the right. The smaller arrows represent the flow of data.

Collision Manager

The collision manager (on the right side in Figure 11–2) represents a central area where all data collisions in the database network would be resolved. The collision manager could be located on a separate machine. The results of data collision resolution could be transferred to the master database, then propagated to all other sites.
