Configure OPC UA in a High-Availability Cluster

This topic describes how to set up OPC UA servers or clients to operate in a clustered environment.

Procedure

Log in to Operations Hub (Node1 or Node2) and create a data source with OPC UA configuration.
For steps to create a data source, refer to Add a Data Source with OPC UA Configuration (Classic).
Open Windows Failover Cluster Manager and switch to the other node in the cluster.
Log in to Operations Hub (on the other node) and open the data source created in step 1.
Select Test Connection.
A message appears indicating that the test connection has failed.

In the next steps we shall fix the issue with connection failure.
On the node that is currently active, navigate to C:\Program Files\GE\Operations Hub\BrowseService.
Locate and open the ServerConfig.xml file in a text editor.
Search for the term [NodeName] and replace (along with the parenthesis) all the instances (ignore instances within comments) with the name of the Node, where OPC UA was initially configured (the Node in step 1).
Save and close the ServerConfig.xml file.
Open the Windows Services Management Console and restart Proficy Operations Hub OPC UA Browse Service.
Open the data source created with OPC UA configuration again and test the connection.
