notifyRemoteBrokerIsNoLongerAvailable

public void notifyRemoteBrokerIsNoLongerAvailable(String remoteBrokerUrl,
                                         String errorMessage)

Description copied from interface: RemoteQueueTransferListener

Callback when an entire remote broker is not available. This is only triggered when something like an IOException occurs and that means that likely every RemoteQueue is now no longer available on this system. NOTE: The action to take when this callback occurs is to call updateRemoteBrokerState with a state of NOT_AVAILABLE on the DistributedQueueState.

Specified by:

notifyRemoteBrokerIsNoLongerAvailable in interface RemoteQueueTransferListener

Parameters:

remoteBrokerUrl - The url of the RemoteBroker to mark as Not Available

notifyQueueOnRemoteBrokerIsNoLongerAvailable

public void notifyQueueOnRemoteBrokerIsNoLongerAvailable(String remoteBrokerUrl,
                                                String queueName)

Description copied from interface: RemoteQueueTransferListener

Callback when only a specific queue is now no longer available on a Remote Broker. This is triggered when something like a transfer response of "No Local Queue" is received from a Remote Broker. This error indicates that the Remote Broker is still "up", but that just this particular queue is now no longer available. NOTE: The action to take when this callback occurs is to call updateRemoteQueueWeight with a "zero weight" on the DistributedQueueState.

Specified by:

notifyQueueOnRemoteBrokerIsNoLongerAvailable in interface RemoteQueueTransferListener

Parameters:

remoteBrokerUrl - The url of the RemoteBroker to mark as Not Available

queueName - The name of the queue

run

public void run()

Specified by:
