Disabling and Enabling a webMethods Messaging Trigger

Integration Server 10.7 | Publish-Subscribe Developer’s Guide | Working with webMethods Messaging Triggers | Disabling and Enabling a webMethods Messaging Trigger

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

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

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

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

When you disable a 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 a webMethods messaging trigger during trigger service execution.

To disable or enable a webMethods messaging trigger

1. In the Package Navigator view of Designer, open the 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 webMethods messaging trigger.
True	Enable the webMethods messaging trigger.

3. Click File > Save.

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