Cluster Troubleshooting

• Cluster frontend is unresponsive
  • Check if the Coordinator(s) in question are started up.
  • Check if all processes have been started up with the same . If not ensure that the used across the cluster nodes is identical for every process.
  • Check if all cluster nodes have been started with SSL either dis- or enabled. If not decide what mode of operation you would like to run your cluster in, and consistently stick with for all Agents, Coordinators and DB-Servers.
• Cluster front end announces errors on any number of nodes
  • This is an indication that the Agency is running but either Coordinators or DB-Servers are disconnected or shut down. Establish network connection to or start the according nodes.
