Class ReliableMessagingFeature

  • All Implemented Interfaces:
    StickyFeature

    @ManagedData
    public class ReliableMessagingFeature
    extends javax.xml.ws.WebServiceFeature
    implements StickyFeature
    Reliable messaging feature is an implementation of WebServiceFeature that configures Metro Reliable Messaging runtime functionality.

    Since there is a lot to configure in Reliable Messaging domain, to build create an instance of ReliableMessagingFeature, use a convenience ReliableMessagingFeatureBuilder builder class.

      • getProtocolVersion

        @ManagedAttribute
        public RmProtocolVersion getProtocolVersion()
        Specifies which WS-RM version SOAP messages and SOAP message headers should be used for communication between RM source and RM destination
        Returns:
        version currently configured for the feature. If not set explicitly, the default value is specified by a call to RmVersion#getDefault().
      • getSequenceInactivityTimeout

        @ManagedAttribute
        public long getSequenceInactivityTimeout()
        Specifies a period of inactivity for a Sequence in ms.
        Returns:
        currently configured sequence inactivity timeout. If not set explicitly, the default value is specified by DEFAULT_SEQUENCE_INACTIVITY_TIMEOUT constant.
      • getDeliveryAssurance

        @ManagedAttribute
        public ReliableMessagingFeature.DeliveryAssurance getDeliveryAssurance()
        Specifies the message delivery quality of service between the RM and application layer. It expresses the delivery assurance in effect between the RM Destination and its corresponding application destination, and it also indicates requirements on any RM Source that transmits messages to this RM destination. Conversely when used by an RM Source it expresses the delivery assurance in effect between the RM Source and its corresponding application source, as well as indicating requirements on any RM Destination that receives messages from this RM Source. In either case the delivery assurance does not affect the messages transmitted on the wire.
        Returns:
        currently configured delivery assurance mode. If not set explicitly, the default value is specified by a call to ReliableMessagingFeature.DeliveryAssurance.getDefault().
        See Also:
        ReliableMessagingFeature.DeliveryAssurance
      • isOrderedDeliveryEnabled

        @ManagedAttribute
        public boolean isOrderedDeliveryEnabled()

        Specifies a requirement that messages from each individual Sequence are to be delivered in the same order they have been sent by the Application Source. The RM Source will ensure that the ordinal position of each message in the Sequence (as indicated by a message Sequence number) is consistent with the order in which the messages have been sent from the Application Source. The RM Destination will deliver received messages for each Sequence in the order indicated by the message numbering.

        In-order delivery can be used in combination with any of the ReliableMessagingFeature.DeliveryAssurance values, and the requirements of those values will also be met. In particular if the ReliableMessagingFeature.DeliveryAssurance.AT_LEAST_ONCE or ReliableMessagingFeature.DeliveryAssurance.EXACTLY_ONCE value is applied and the RM Destination detects a gap in the Sequence then the RM Destination will not deliver any subsequent messages from that Sequence until the missing messages are received or until the Sequence is closed.

        Returns:
        true if the ordered delivery si required, false otherwise. If not set explicitly, the default value is false.
      • getDestinationBufferQuota

        @ManagedAttribute
        public long getDestinationBufferQuota()
        This attribute may be used together with ordered delivery requirement. It specifies the maximum number of out-of-order unprocessed request messages that may be stored in the unprocessed request message buffer within the RM destination before the RM destination starts rejecting new request messages.
        Returns:
        currently configured flow control buffer on the destination. If not set explicitly, the default value is specified by DEFAULT_DESTINATION_BUFFER_QUOTA constant.
      • getMessageRetransmissionInterval

        @ManagedAttribute
        public long getMessageRetransmissionInterval()
        Specifies how long the RM Source will wait after transmitting a message before retransmitting the message if no acknowledgement arrives.
        Returns:
        currently configured base retransmission interval. If not set explicitly, the default value is specified by DEFAULT_MESSAGE_RETRANSMISSION_INTERVAL constant.
      • getMaxMessageRetransmissionCount

        @ManagedAttribute
        public long getMaxMessageRetransmissionCount()
        A message is considered to be transferred if its delivery at the recipient has been acknowledged by the recipient. If an acknowledgment has not been received within a certain amount of time for a message that has been transmitted, the infrastructure automatically retransmits the message. By default, the number of retransmissions is not limited. This can be checked by a call to #isMessageRetransmissionLimited() method. In case the #isMessageRetransmissionLimited() returns true, the infrastructure tries to send the message for at most a getMaxMessageRetransmissionCount() number of times. Not receiving an acknowledgment before this limit is reached is considered to be a fatal communication failure, and causes the RM session to fail. The infrastructure uses a back-off algorithm retrieved via getRetransmissionBackoffAlgorithm() to determine when to retransmit, based on the configured base retransmission time retrieved via a call to getMessageRetransmissionInterval().
        Returns:
        maximum number of message transmission retries
      • canRetransmitMessage

        public boolean canRetransmitMessage​(long nextRetransmissionCount)
        Returns true if the next attempt to retransmit a message indicated by nextRetransmissionCount input parameter is allowed as per current feature configuration.
        Parameters:
        nextRetransmissionCount - indicates the ordinal number of the next (potential) attempt to retransmit a single message
        Returns:
        true if it is possible to retransmit a message, false otherwise.
        See Also:
        getMaxMessageRetransmissionCount()
      • getMaxRmSessionControlMessageResendAttempts

        @ManagedAttribute
        public long getMaxRmSessionControlMessageResendAttempts()
        The infrastructure tries to send each RM session protocol control message such as CreateSequence, CloseSequence, TerminateSequence at most a getMaxRmSessionControlMessageResendAttempts() number of times. Not receiving an acknowledgment before this limit is reached is considered a fatal communication failure, and causes the RM session to fail.
        Returns:
        maximum number of reliable messaging session handshake message transmission attempts
      • getAcknowledgementTransmissionInterval

        @ManagedAttribute
        public long getAcknowledgementTransmissionInterval()
        Specifies the duration after which the RM Destination will transmit an acknowledgement. Specified in milliseconds.
        Returns:
        currently configured acknowledgement transmission interval. If not set explicitly, the default value is specified by the DEFAULT_ACKNOWLEDGEMENT_TRANSMISSION_INTERVAL constant.
      • getAckRequestTransmissionInterval

        @ManagedAttribute
        public long getAckRequestTransmissionInterval()
        Specifies interval between sending subsequent acknowledgement request messages by an RM Source in case of any unacknowledged messages on the sequence.
        Returns:
        currently configured acknowledgement request transmission interval. If not set explicitly, the default value is specified by the DEFAULT_ACK_REQUEST_TRANSMISSION_INTERVAL constant.
      • getCloseSequenceOperationTimeout

        @ManagedAttribute
        public long getCloseSequenceOperationTimeout()
        Specifies the timeout for a CloseSequenceRequest message. If no response is returned from RM destination before the timout expires, the sequence is automatically closed by the RM source and all associated resources are released.
        Returns:
        currently configured close sequence operation timeout. If not set explicitly, the default value is specified by the DEFAULT_CLOSE_SEQUENCE_OPERATION_TIMEOUT constant.
      • isPersistenceEnabled

        @ManagedAttribute
        public boolean isPersistenceEnabled()
        Specifies whether the runtime should use persistent message storage or not.
