39.1 Planning Your Messenger System in a
Heartbeat Cluster
Because the Messenger agents are not associated with GroupWise domains or post offices, the
Messenger agents are easier to implement in a cluster than are the GroupWise agents. The
"Messenger Clustering Worksheet" on page 240
Messenger agents in a clustering environment. You should print the worksheet and fill it out as you
complete the tasks listed below:
Section 39.1.1, "Planning a Cluster Resource Group for the Messenger Agents," on page 369
Section 39.1.2, "Recording the Messenger Agents' Secondary IP Address," on page 370
Section 39.1.3, "Determining Appropriate Constraints for the Messenger Agents," on page 370
Section 39.1.4, "Planning the Messenger Agent Installation," on page 371
39.1.1 Planning a Cluster Resource Group for the Messenger
Agents
As with the GroupWise agents, the Messenger agents need cluster nodes, native Heartbeat
resources, Messenger resources, and a cluster resource group in order to function in your Heartbeat
cluster. If you put the Messenger agents in the same cluster resource group, they fail over together. If
you put them in separate cluster resource groups, then they fail over separately.
For a review of these cluster components, see
Linux," on page 134.
