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. Click 服務整合 -> 匯流排 -> bus_name.
  2. Specify the following properties for the bus:
    說明
    跨引擎傳輸鏈

    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.

    捨棄訊息
    Select this option to indicate that after a queue has been deleted, any messages remaining in the data store for that queue should be discarded.
    啟用重新載入配置
    Select this option to enable automatic update of configuration information on all the messaging engines on the bus.

    Changes to bus destinations or mediations are applied when destinations or mediations are added to or removed from the bus.

    Changes to the modifiable configuration information for any foreign bus connections are also updated automatically. The time when these changes take effect varies:

    Foreign Bus Connection properties
    Immediately
    WebSphere® MQ link properties
    On channel restart, except Description (immediately), and Initial State (on messaging engine restart)
    MQ sender channel properties
    On channel restart, except Initial State (on messaging engine restart or sender channel creation)
    MQ receiver channel properties
    On channel restart, except Initial State (on messaging engine restart or receiver channel creation)
    Publish/subscribe broker profile (0 to n) properties
    Immediately
    Service integration bus link properties
    On link restart, except Description (immediately), and Initial State (on messaging engine restart or link creation)

    To ensure that dynamic configuration updates are made on an application server, click 伺服器 -> 伺服器類型 -> WebSphere Application Server -> server_name -> [伺服器傳訊] SIB 服務 then select Configuration reload enabled.

    To ensure that dynamic configuration updates are made to each node, click 系統管理 -> 主控台喜好設定 to display the Console Preferences window then select Synchronize changes with nodes.

    預設傳訊引擎高訊息臨界值
    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.
  3. 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)
  4. Click OK.
  5. 儲存對主要配置所做的變更。
