Description

Interface Summary

ClusterLeaderListener	Listener that is called when the local server becomes the cluster leader.
ClusterMasterRemote
LeaseLostListener
LeaseObtainedListener
Leasing	The Leasing interface provides access to leasing services, which allow servers in the cluster to gain exclusive ownership over named entities.
LeasingBasis	A LeasingBasis provides the underpinnings for implementing the LeaseManager.
MigrationData	Information about one ongoing or completed migration.
RemoteLeasingBasis	A RemoteLeasingBasis provides a remote implementation of LeasingBasis.
SingletonService	This interface defines a stateless lightweight singeton service that has the following contract: Activate is invoked on one and only one server in a cluster Deactivate can be called anytime after activate is called.

Class Summary

ConfigMigrationProcessor
DatabaseLeasingBasis	LeasingBasis that leverages an HA-database for lease ownership.
DomainMigrationHistoryImpl	Holds the migration history of all domain members for exposure through console.
LeaseManager	Implementation of the Leasing interface.
LeaseManagerFactory
MigratableServerService	MigratableServerService registers ServerMigrationCoordinator with the MBean server and creates the ClusterMaster Leasing implementation.
MigrationDataRuntimeMBeanImpl
MigrationDebugLogger
QueryDumper
QueryHelper	Helper class for ClusterMaster to determine servers that are unresponsive and to find lease owners.
QueryHelperImpl	Helper class for ClusterMaster to determine servers that are unresponsive and to find lease owners.
RemoteLeasingBasisImpl	Remote implementation of RemoteLeasingBasis as a wrapper around a LeasingBasis.
ReplicatedLeasingBasis	LeasingBasis that delegates to replicated remote instances.
SimpleLeasingBasis	Dumb LeasingBasis that holds leases in-memory.
SimpleLeasingBasis.LeaseEntry
SingletonServicesDebugLogger

Exception Summary

ClusterReformationInProgressException	ClusterReformationInProgressException is just a tagging exception on top of IOException to indicate to the caller that consensus is going on right now.
DatabaseUnreachableException
LeasingException
MissedHeartbeatException	Exception that is sent by a LeasingBasis implementation if it failed to deliver a heartbeat in a suitable time interval.
