Disabling and Enabling IBM webMethods Messaging Trigger

Integration Server 11.1 | Publish-Subscribe Developer’s Guide | Working with IBM webMethods Messaging Triggers | Disabling and Enabling IBM webMethods Messaging Trigger

Disabling and Enabling IBM webMethods Messaging Trigger in a Cluster or Non-Clustered Group

You can use the Enabled property to disable or enable IBM webMethods messaging trigger.

When you disable IBM webMethods messaging trigger that receives messages from IBM webMethods Broker, Integration Server disconnects the trigger client on the IBM webMethods Broker. The IBM webMethods Broker removes the document subscriptions created by the trigger client. The IBM webMethods Broker does not place published documents in client queues for disabled IBM webMethods messaging triggers. When you enable a disabled IBM webMethods messaging trigger, Integration Server connects the trigger client to the IBM webMethods Broker and re-establishes the document subscriptions on the IBM webMethods Broker.

Note:
You can also suspend document retrieval and document processing for IBM webMethods messaging trigger. Unlike disabling IBM webMethods messaging trigger, suspending retrieval and processing does not destroy the IBM webMethods Broker client queue. The IBM webMethods Broker continues to enqueue documents for suspended IBM webMethods messaging triggers. However, Integration Server does not retrieve or process documents for suspended IBM webMethods messaging triggers. For more information about suspending IBM webMethods messaging triggers, see IBM webMethods Integration Server Administrator’s Guide.

When you disable IBM webMethods messaging trigger that receives messages from Universal Messaging, the corresponding durable subscription remains intact. Universal Messaging enqueues any messages to which the trigger subscribes. The trigger will receive the messages when it is re-enabled.

You cannot disable IBM webMethods messaging trigger during trigger service execution.

To disable or enable IBM webMethods messaging trigger

1. In the Package Navigator view of Designer, open the IBM webMethods messaging trigger that you want to disable or enable.

2. In the Properties view, under General, set Enabled to one of the following:

Select...	To...
False	Disable the IBM webMethods messaging trigger.
True	Enable the IBM webMethods messaging trigger.

3. Click File > Save.

You can enable only valid IBM webMethods messaging triggers. If the IBM webMethods messaging trigger is not valid, Designer displays an error message when you save the IBM webMethods messaging trigger prompting you to cancel the save or continue the save with a disabled IBM webMethods messaging trigger. For more information about requirements for a valid IBM webMethods messaging trigger, see IBM webMethods Messaging Trigger Requirements.
