Agent Clusters are one or more JobScheduler Agents that are accessed by a single URI. This means that there are two components to each Agent Cluster: the Agent or Agents itself / themselves and the URI common Process Class. The Process Class defines the address or addresses - i.e the address of the Agent Cluster, which is defined in a separate Process Class object. the URIs - of the individual Agents as well as the maximum number of tasks that the Cluster may execute at any one time.
Process Classes are also JobScheduler resources and shown in the JOC Cockpit Resources / Process Classes view (see below). Each Process Class specifying a group of one or more Universal Agents that are reached through a common address is considered as a separate Agent Cluster. (Conversely, Process Classes not including agent address information are not considered as Agent Clusters.)
This means that a group of Universal Agents , separately specified in two only one Process Classes, Class will be listed as two separate one Agent Clusters Cluster, and a single Universal Agent operating "stand-alone" will be listed as an Agent Cluster. Note that a Process Class not including agent address information will not be considered as an Agent Cluster.but listed in three Process Classes will be listed as three Agent Clusters.
