Overview

This MBean represents a WebLogic messaging bridge. A messaging bridge instance interoperates between separate implementations of WebLogic JMS or between WebLogic JMS and another messaging product.

For WebLogic JMS and third-party JMS products, a messaging bridge communicates with a configured source and target destinations using the resource adapters provided with WebLogic Server.

    Attributes

    This section describes the following attributes:


    AsyncEnabled

    Specifies if a messaging bridge instance forwards in asynchronous messaging mode.

    AsyncEnabled only applies to messaging bridge instances whose source destination supports asynchronous receiving. Messaging bridges instances that forward in asynchronous mode are driven by the source destination. A messaging bridge instance listens for messages and forwards them as they arrive. When AsyncEnabled is not selected, a bridge instance is forced to work in synchronous mode, even if the source supports asynchronous receiving.

    Note: For a messaging bridge instance with a QOS of Exactly-once to work in asynchronous mode, the source destination has to support the MDBTransaction interface. Otherwise, the bridge automatically switches to synchronous mode if it detects that MDBTransaction is not supported by the source destination.

           
    Privileges Read/Write
    Typeboolean
    Default Valuetrue

    BatchInterval

    The maximum amount of time, in milliseconds, that a messaging bridge instance waits before sending a batch of messages in one transaction, regardless of whether the Batch Size has been reached or not.

           
    Privileges Read/Write
    Typelong
    Default Value-1

    BatchSize

    The number of messages that are processed within one transaction.

    Batch Size only applies to a messaging bridge instance forwarding messages in synchronous mode and has a QOS (quality of service) that requires two-phase transactions.

           
    Privileges Read/Write
    Typeint
    Default Value10
    Minimum value0

    CachingDisabled

    Private property that disables caching in proxies.

           
    Privileges Read only
    Typeboolean
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    DeploymentOrder

    A priority that the server uses to determine when it deploys an item. The priority is relative to other deployable items of the same type.

    For example, the server prioritizes and deploys all EJBs before it prioritizes and deploys startup classes.

    Items with the lowest Deployment Order value are deployed first. There is no guarantee on the order of deployments with equal Deployment Order values. There is no guarantee of ordering across clusters.

           
    Privileges Read/Write
    Typeint
    Default Value1000
    Minimum value0
    Maximum value2147483647

    DurabilityEnabled

    Specifies whether or not the messaging bridge allows durable messages.

    When enabled and the source destination is a JMS topic, a messaging bridge instance uses a durable subscription to ensure that no messages are lost in the event of a failure. DurabilityEnabled ignored if the source destination is a JMS queue.

           
    Privileges Read/Write
    Typeboolean
    Default Valuetrue

    IdleTimeMaximum

    The maximum amount of time, in seconds, that a messaging bridge instance remains idle.

           
    Privileges Read/Write
    Typeint
    Default Value60
    Minimum value0
    Maximum value2147483647

    Operations

    This section describes the following operations:


    addTarget

    You can add a target to specify additional servers on which the deployment can be deployed. The targets must be either clusters or servers.

       
    Operation Name"addTarget"
    ParametersObject [] {  target }

    where:

    • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

      The feature to be added to the Target attribute

    SignatureString [] { "weblogic.management.configuration.TargetMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.DistributedManagementException

    freezeCurrentValue

    If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

    Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

    Note:

    To insure that you are freezing the default value, invoke the restoreDefaultValue operation before you invoke this.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

    Deprecated. 9.0.0.0

       
    Operation Name"freezeCurrentValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException
    • javax.management.MBeanException

    isSet

    Returns true if the specified attribute has been set explicitly in this MBean instance.

       
    Operation Name"isSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to check

    SignatureString [] { "java.lang.String" }
    Returns boolean

    removeTarget

    Removes the value of the addTarget attribute.

    For more information, see:

       
    Operation Name"removeTarget"
    ParametersObject [] {  target }

    where:

    • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

      target

    SignatureString [] { "weblogic.management.configuration.TargetMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.DistributedManagementException

    restoreDefaultValue

    If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

    Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the freezeCurrentValue operation.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

    Deprecated. 9.0.0.0

       
    Operation Name"restoreDefaultValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException

    unSet

    Restore the given property to its default value.

       
    Operation Name"unSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to restore

    SignatureString [] { "java.lang.String" }
    Returns void
