In shared application mode

Stop all cluster nodes except one.
Log on to the cluster node and install Message Connector on the shared disk.
If this is the first node:
1. Start the Message Connector Configuration utility.
2. In the Storage file field (General tab), type the path and name of the storage file on the shared disk.
3. It is recommended to change the Trace location (Trace settings tab) to the shared disk as well.
4. Save the configuration.
Stop the Message Connector service.
Change the Windows user under which Message Connector is running. The user must be a domain user having local administrator rights (same user for all cluster nodes).
Stop the cluster node.
Repeat steps 1, 2, 4, 5, and 6 for all other nodes.
Continue with Configure clustered service and IP address.

Message Connector configuration behaves differently when running in a clustered environment:

When Message Connector is installed in shared application mode, the shortcuts to "Message Connector Configuration" and "Message Connector Monitor" in the start menu may only be run on the cluster node, that is, the current owner of the clustered Message Connector service. The shared disk with the Message Connector working folder is only available to this one cluster node.

Do not start the configuration shortcut on other than the active node!

To prevent erroneous situations, we recommend that you to use the remote desktop connection to the cluster and start the configuration tool there. For the remote connection, use the IP address described in Configure clustered service and IP address.
When the Message Connector runs as a clustered service, the Message Connector Configuration application cannot restart the service, because the service is under control of the cluster. To restart the service, save configuration changes, then take the service offline via Failover Cluster Management, and bring it online again.
