Adding or modifying topic mappings on the WebSphere MQ link publish/subscribe broker

Define topic mappings on a publish/subscribe broker profile, part of the publish/subscribe bridge on a WebSphere® MQ link. A topic mapping is a mapping between a topic on a service integration bus and a stream queue and subscription point provided by a WebSphere MQ broker.

Before you begin

You have to know the bus name, messaging engine name, WebSphere MQ link name and the name of the broker profile on which you intend to define the topic mappings.

About this task

Topic mappings are associated with a WebSphere MQ link publish/subscribe broker profile. Together, the profile and topic mappings enable publication and subscription with a broker in a IBM MQ network.

Note: Publication messages forwarded to a message broker in the IBM MQ network are republished on the same topic as they were originally published to in the service integration bus topic space, and vice versa.

To define topic mappings, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click 服務整合 -> 匯流排 -> bus_name -> [拓蹼] 傳訊引擎 -> engine_name -> [其他內容] IBM MQ 鏈結 -> link_name -> [其他內容] 發佈/訂閱分配管理系統設定檔 -> profile_name -> [其他內容] 主題對映
  2. In the content pane, either click New to add a new topic mapping, or click the name of a existing topic mapping that you want to modify. The 主題對映 [設定] form is displayed.
  3. Type the topic name.

    The topic name can contain wildcards that are in the service integration bus syntax. For more information, see Wild cards in topic mapping.

  4. Select the name of the topic space that contains the topic. If you don't select a name the default is used.
  5. Select the direction of publication flow. The direction of publication flow can be:
    雙向
    匯流排和 IBM MQ 之間的雙向訊息流程。
    目的地 IBM MQ
    只從匯流排到 IBM MQ 的訊息流程。 That is, from WebSphere Application Server to a message broker in the IBM MQ network.
    來源 IBM MQ
    只從 IBM MQ 到匯流排的訊息流程。 That is, from a message broker in the IBM MQ network to WebSphere Application Server.
  6. Select the broker stream queue you want to use. If the queue you require is not on the list, click other, please specify then enter the name of the broker stream queue.

    The broker stream queue in this instance is a queue on the IBM MQ queue manager to which the message broker is connected. This queue is being used as the input node for a message flow containing a publication node. Messages sent to this queue are processed by the message broker, then published to applications that have subscribed on the topic specified in the message.

    Stream names are case sensitive.

    After you type a new name, then save your changes, the name becomes available for selection in the drop-down list.

  7. Select the IBM MQ message broker subscription point from which the service integration bus receives messages. If the subscription point you require is not on the list, click other, please specify then enter the name of the subscription point.

    The default subscription point is used if no value is specified.

    After you type a new name, then save your changes, the name becomes available for selection in the drop-down list.

  8. Click OK.
  9. 儲存對主要配置所做的變更。
  10. Optional: If you have enabled dynamic configuration updates, the changes take effect immediately. Otherwise, restart the application server.
