shutdown

public void shutdown()
              throws ClusteringFault

Shutdown the cluster. This member will leave the cluster when this method is called.

Specified by:

shutdown in interface ClusteringAgent

Throws:

ClusteringFault - If an error occurs while shutting down

setConfigurationContext

public void setConfigurationContext(ConfigurationContext configurationContext)

Specified by:

synchronizeAllMembers

public boolean synchronizeAllMembers()

Method to check whether all members in the cluster have to be kept in sync at all times. Typically, this will require each member in the cluster to ACKnowledge receipt of a particular message, which may have a significant performance hit.

Returns:

true - if all members in the cluster should be kept in sync at all times, false otherwise
