Configuring bus properties

You can configure how many messages the bus can handle, when to discard messages, and which messaging engines the bus can communicate with. You can also specify changes that can be made to the bus that do not require a restart of the messaging engines.

About this task

You configure bus properties after you have created a bus. To configure the properties of a bus, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click Service integration > Buses. A list of buses is displayed in the content pane.
  2. In the content pane, select the bus that you want to configure.
  3. Specify the following properties for the bus:
    Description
    A service integration bus supports applications using message-based and service-oriented architectures. A bus is a group of interconnected servers and clusters that have been added as members of the bus. Applications connect to a bus at one of the messaging engines associated with its bus members.
    Inter-engine transport chain
    The transport chain used for communication between messaging engines in this bus.

    The transport chain must correspond to one of the transport chains defined in the Messaging engine inbound transports settings for the server. All servers automatically have a number of transport chains defined to them, and it is also possible to create new transport chains.

    When you specify the name of a transport chain, that chain must be defined to all servers hosting messaging engines in the bus. Otherwise, some messaging engines might not be able to communicate with their peers in the bus.

    When the use of permitted chains is enforced and a protocol is not specified for intra-bus communications then InboundSecureMessaging is assumed instead of InboundBasicMessaging. This can be overridden by setting the protocol attribute in the bus configuration. If InboundSecureMessaging is not a permitted chain then an error occurs.

    Discard messages
    Whether messages on a deleted message point should be retained at a system exception destination or can be discarded. Select this option to indicate that after a queue has been deleted, any messages left in the data store for that queue should be discarded.
    Configuration reload enabled
    Select this option to enable certain changes to the bus configuration to be applied without requiring the messaging engines to be restarted. These changes are applied when destinations or mediations are added to or removed from the bus. This option also controls whether automatic updates occur on all the messaging engines on the bus.
    High message threshold
    A threshold above which the messaging system will take action to limit the addition of more messages to a message point. When a messaging engine is created on the bus, the value of this property is used to set the default high message threshold for the messaging engine.
  4. Specify topology, destination resources, Web services and additional properties for the bus, as required. To restrict the number of audit messages, add a custom property called audit.bus.authentication with one of the following values:
    • all (audit all attempts to authenticate to the bus)
    • failure (audit only failure to authenticate to the bus)
    • none (do not audit any attempts to authenticate to the bus)
  5. Click OK.
  6. Save your changes to the master configuration.
