Hi, everybody I want to know if a cluster replicates data between HASingleton instances:
I mean if a backup instance of a HASingleton contains the same data of an active node HASingleton.
I?m asking this cause one of my applications controls session states, in a different way (not using the http mechanism) and I do it using a Hash with the session information.
So as the session controller is a singleton I want to know if I will lose the session data or not.
No, there is no replication of data between HASingleton instances; there is only notification when a cluster node becomes a master and the instance needs to begin providing the service. Replication of state would have to be implemented as part of the singleton service (e.g. by deploying a JBossCache or using the JBoss DistributedState service).
