Administered subscribers [Settings]
An administered subscriber provides a mechanism for the WS-Notification service point to subscribe to an external notification producer at server startup time.
To view this page in the console, click one of the following paths:
- Service integration -> WS-Notification -> Services -> service_name -> [Additional Properties] WS-Notification service points -> point_name -> Administered subscribers -> subscriber_name
- Service integration -> Buses -> bus_name -> [Services] WS-Notification services -> service_name -> [Additional Properties] WS-Notification service points -> point_name -> Administered subscribers -> subscriber_name
An administered subscriber contains the name of a NotificationProducer application or a (different) NotificationBroker endpoint and details of a subscription request (for example topic) that the WS-Notification service point should register as part of the server startup procedure. This enables us to pre-configure links between the NotificationBroker and a NotificationProducer, which can be a remote NotificationBroker or a NotificationProducer application.
Configuration tab
The Configuration tab shows configuration properties for this object. These property values are preserved even if the runtime environment is stopped then restarted.
General Properties
External web service endpoint
The URL of the external web service to which the service should subscribe.
That is, the endpoint reference (web address) of a notification producer or notification broker application. For example http://remoteproducer.com.
Required Data type Yes String
Dialect
The dialect in which the topic is expressed.
Required Data type Yes drop-down list
Topic
The topic on which the service should subscribe.
This describes the class of notification messages that are delivered to the WS-Notification service point. For example stock/IBM. This property can include wildcards if they are supported by the topic dialect that we select.
Required Data type Yes String
Topic namespace
The URI that describes the topic namespace in which the specified topic is defined.
Required Data type No Custom
Remote subscription timeout
The length of time in hours after which the remote subscription will expire if not renewed by the server.
This timeout minimizes the potential for orphaned subscriptions in the remote web service if the local server is uninstalled. Note that this field does not indicate the time at which the remote subscription is due to expire. Set the timeout length to something larger than the maximum length of time that the server is expected to remain offline, otherwise the stream of messages from the remote web service might be interrupted. While the server is running it occasionally renews the remote subscription termination time (with the specified timeout) to prevent it from expiring during normal operation. If not specified, this timeout defaults to 24 (hours).
Required Data type Range Yes Integer 1 through 2147483647
