    • the first Agent that is configured to execute jobs for the process class will be contacted.
    • if the first Agent is not available then the next Agent listed in the process class configuration will be contacted
    • this procedure will be repeated until an Agent is found that can execute the job.
  • Use cases for this scenario include
    • all Agents running on different server nodes: the switch to the next available Agent implements a fail-over to the next server node.
    • a number of Agents running on the same server node: the switch to the next available Agent implements redundancy  of Agents within a single server node.
