Notification that the cluster has changed state with respect to the resource adaptor entity that attached the listener.
A running node is a node that satisfies the following conditions:
the node is a member of the cluster’s primary component
the resource adaptor entity is in the Active state on the node
the SLEE is in the Running state on the node
The running set is a superset of the joined set and has an empty intersection with the left set.
NB: A resource adaptor entity will leave the running state on a node if it or the SLEE transitions to the Stopping state on that node.
