Introduction
Cluster Nodes are Universal Controller instances in a Universal Automation Center system.
Universal Automation Center contains more than one cluster node only if it is operating in a High Availability environment.
Displaying Information About Cluster Nodes
When you start a cluster node for the first time, the Controller automatically creates a database record for that cluster node. You can view these records for details and status information.
Step 1 | From the Agents & Connections navigation pane, select System > Cluster Nodes. The Cluster Nodes list displays: |
---|---|
Step 2 | To display the Details for a cluster node on the list, click the Details icon next to the Node Id of the OMS Server, or click anywhere in the OMS Server row. |
