This graphic shows one cluster with three managed servers. Server 1 contains DT Member 1; Server 2 contains DT Member 2; and Server 3 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 a shared subscription. Each server has 3 MDB instances. Each of the shared subscription points to an MDB instance in each managed server. That is, there are 3 MDB instances in each server, and each shared subscription of each DT member points to one of them. For example, the shared subscription on DT Member 1 points to MDB Instance 1 on Server 1, MDB Instance 1 on Server 2, and MDB Instance 1 on Server 3. The shared subscription on DT Member 2 points to MDB Instance 2 on Server 1, MDB Instance 2 on Server 2, and MDB Instance 2 on Server 3.
