      protected static final StringManager sm
      The string manager for this package.

    • DEFAULT_REPL_TIMEOUT

      protected static final long DEFAULT_REPL_TIMEOUT
      See Also:

    • name

      protected String name
      The name of this manager

  • Constructor Details

    • BackupManager

      public BackupManager()
      Constructor, just calls super()

  • Method Details

    • messageDataReceived

      public void messageDataReceived(ClusterMessage msg)
      Description copied from interface: ClusterManager
      A message was received from another node, this is the callback method to implement if you are interested in receiving replication messages.
      Specified by:
      messageDataReceived in interface ClusterManager
      Parameters:
      msg - - the message received.

    • requestCompleted

      public ClusterMessage requestCompleted(String sessionId)
      Description copied from interface: ClusterManager
      When the request has been completed, the replication valve will notify the manager, and the manager will decide whether any replication is needed or not. If there is a need for replication, the manager will create a session message and that will be replicated. The cluster determines where it gets sent.
      Specified by:
      requestCompleted in interface ClusterManager
      Parameters:
      sessionId - - the sessionId that just completed.
      Returns:
      a SessionMessage to be sent.

    • objectMadePrimary

      public void objectMadePrimary(Object key, Object value)
      Specified by:
      objectMadePrimary in interface AbstractReplicatedMap.MapOwner

    • createEmptySession

      public Session createEmptySession()
      Description copied from interface: Manager
      Get a session from the recycled ones or create a new empty one. The PersistentManager manager does not need to create session data because it reads it from the Store.
      Specified by:
      createEmptySession in interface Manager
      Overrides:
      createEmptySession in class ManagerBase
      Returns:
      An empty Session object

    • getName

      public String getName()
      Description copied from interface: ClusterManager
      Return the name of the manager, at host /context name and at engine hostname+/context.
      Specified by:
      getName in interface ClusterManager
      Overrides:
      getName in class ManagerBase
      Returns:
      The descriptive short name of this Manager implementation.

    • startInternal

      protected void startInternal() throws LifecycleException
      Start this component and implement the requirements of LifecycleBase.startInternal(). Starts the cluster communication channel, this will connect with the other nodes in the cluster, and request the current session state to be transferred to this node.
      Overrides:
      startInternal in class ClusterManagerBase
      Throws:
      LifecycleException - if this component detects a fatal error that prevents this component from being used

    • getMapName

      public String getMapName()

    • stopInternal

      protected void stopInternal() throws LifecycleException
      Stop this component and implement the requirements of LifecycleBase.stopInternal(). This will disconnect the cluster communication channel and stop the listener thread.
      Overrides:
      stopInternal in class ClusterManagerBase
      Throws:
      LifecycleException - if this component detects a fatal error that prevents this component from being used

    • setName

      public void setName(String name)
      Description copied from interface: ClusterManager
      Set the name of the manager, at host /context name and at engine hostname+/context
