Listing or deleting active WS-Notification subscriptions

List the subscriptions that exist at run time for a particular WS-Notification service point, or for all service points for a particular WS-Notification service.

About this task

The runtime panels for WS-Notification subscriptions list the durable subscriptions that have been created by a WS-Notification service point in response to "Subscribe" requests from WS-Notification applications. 您可以檢視該訂閱的相關聯訂閱名稱 (ID)、主題和其他資訊,且您可以檢視存放在延緩遞送之可延續的訂閱上的訊息。您也可以刪除訂閱。 例如,在 應用程式表現不佳之後,進行清理。

Note: WS-Notification 訂閱和發佈者登錄資源兩者皆含有排定終止作業的概念,其中,應用程式會指出一段時間,一旦過了此時間,即會銷毀資源。"「表現不佳」" 在這裡說明應用程式要求某個資源有無限的生命期限,但在它離開(永不返回)之前,卻不明確刪除這個資源。

A subscription created by a WS-Notification application can contain more than one topic expression, and each of these topic expressions can be in a different namespace, which can result in service integration bus subscriptions being created in multiple topic spaces.

To display a list of WS-Notification subscriptions that exist at run time, use the administrative console to complete the following steps:

Procedure

  1. 請完成下列子步驟之一,以便選擇特定服務點的資訊,或特定服務之所有服務點的聚集資訊:
    1. Optional: 如需特定服務點的執行時期資訊,請導覽至服務整合 -> WS-Notification -> 服務 -> service_name -> [其他內容] WS-Notification 服務點 -> point_name服務整合 -> 匯流排 -> bus_name -> [服務] WS-Notification 服務 -> service_name -> [其他內容] WS-Notification 服務點 -> point_name,然後按一下執行時期標籤。 這時會顯示一個畫面,其中含有鏈結,可連接至這個 WS-Notification 服務點的訂閱、登錄、取出點和受管理訂閱者的相關執行時期資訊。
    2. Optional: 如需特定服務之所有服務點的執行時期聚集資訊,請導覽至服務整合 -> WS-Notification -> 服務 -> service_name服務整合 -> 匯流排 -> bus_name -> [服務] WS-Notification 服務 -> service_name,然後按一下執行時期標籤。 這時會顯示一個畫面,其中含有鏈結,可連接至這個 WS-Notification 服務的訂閱、登錄和取出點的相關執行時期資訊。
  2. Click Subscriptions The 訂閱 [集合] form is displayed. 這份表單顯示這個 WS-Notification 服務點或服務目前在作用中的所有訂閱。 這份收集表單含有每一個清單項目的如下資訊:
    訂閱 ID
    Topics
    An array of topic names. Note that this will usually only contain one element.
    遞送狀態
    In normal operation the subscription will show a state of OK. Other states are PAUSED, indicating that the application has paused the subscription as defined by the WS-Notification standards, or ERROR, indicating that the last attempt to deliver an event notification to the notification consumer was not successful. In the error case, more information about the cause of the failure can be found in the SystemOut log.
    Note: 這個主題參照一或多個應用程式伺服器日誌檔。 此外,在分散式和 IBM® i 系統上,另外也建議您可以配置伺服器來使用「高效能可延伸記載 (HPEL)」日誌和追蹤基礎架構,而不使用 SystemOut.logSystemErr.log, trace.logactivity.log 檔案。HPEL 與原生 z/OS® 記載機能也可以一起使用。如果您使用 HPEL,則可以從伺服器設定檔 bin 目錄,利用 LogViewer 指令行工具來存取您所有的日誌和追蹤資訊。請參閱有關利用 HPEL 疑難排解應用程式的資訊,以取得更多使用 HPEL 的相關資訊。
    消費端 EPR
    That is, the endpoint reference to which notification messages are delivered as specified on the subscribe call.
    建立時間
    終止時間
    取出類型
    That is, whether this subscription is being accessed by a pull point. If the asynchronous (push) subscription model is being used, this field displays "No". If a pull point is being used, this field displays "Yes".
    服務整合匯流排訂閱
    This is a link to the service integration bus durable subscription detail panel for the subscriptions that contain data for this object.
  3. Optional: To observe the runtime state of each of the service integration bus durable subscriptions that have been created, click the link in the SIBus subscriptions field.

    If only one durable subscription has been created, the bus durable subscription detail panel is displayed. For more information, see Administering durable subscriptions.

    If multiple durable subscriptions have been created, for example if the WS-Notification subscription is spanned across multiple service integration bus topic spaces, a runtime collection form is displayed that shows the individual bus durable subscriptions. 這份表單顯示這個 WS-Notification 服務點或服務目前在作用中的所有發佈者登錄。
    SIBus subscription
    The service integration bus durable subscription ID. This links to the associated bus durable subscription detail panel. For more information, see Administering durable subscriptions.
    Topics
    The list of topics that are contained within a single service integration bus topic space (and thus durable subscription).

What to do next

To delete one or more WS-Notification subscriptions, and the associated service integration bus durable subscriptions, select the check box next to each subscription name then click Delete.
