Hi,
In Wildfly 10, it is possible to make the whole JEE application HA singleton (active-passive cluster configuration).
In active-active cluster configuration, it is also possible to write a service implementing Singleton Service to manage individual singleton EJB annotated with @Singleton @Clustered so that each active cluster member will have one instance of the singleton EJB, but only one across the cluster will be active.
I am wondering if there is a way to configure a singleton EJB so that only one will be active across a cluster, instead of write a service to manage this function.
Thanks,
Wayne
