Liberty cluster troubleshooting

There are common issues that you might encounter with Liberty clusters.

Problem:
The server is configured to be part of a cluster but the member is not shown to be part of the cluster.
Solution:
A collective server can be configured to be a cluster member while it is running. The new configuration is dynamically updated and published to the collective controller. If there is a problem publishing to the controller, this will affect the server joining the cluster. If a collective server is configured to be a cluster member while the server is stopped, the server will not be a member of a cluster until the server is started.
