This graphic shows two clusters with three managed servers each. Server 1 in Cluster 1 contains DT Member 1; Server 2 in Cluster 1 contains DT Member 2; and Server 3 in Cluster 1 contains DT Member 3. Three messages are received by the DT (indicated by an arrow pointing from 3 messages to the entire DT). Each member contains all three messages, because they are forwarded among the members. Each member has 3 subscriptions. Cluster 2 has three managed servers. Each managed server has 3 MDB instances. Each of the 3 subscriptions points to an MDB instance in each managed server. That is, there are 3 MDB instances in each server, and each subscription of each DT member points to one of them. For example, Subscription 1 on DT Member 1 points to MDB Instance 1 on Server 1 in Cluster 2; Subscription 2 on DT Member 1 points to MDB Instance 1 on Server 2 in Cluster 2; etc.
