WebIn Figure 1, the queue manager STF2 is a member of both the clusters. When a queue manager is a member of more than one cluster, you can take advantage of namelists to reduce the number of definitions you need. Namelists contain a list of names, for example, cluster names. You can create a namelist naming the clusters.
