Selecting Message Processing

To select message processing

1. In the Package Navigator view of Designer, open the webMethods messaging trigger for which you want to specify the message processing mode.

2. In the Properties view, under Message processing, select one of the following for Processing mode:

Select...	To...
Serial	Specify that Integration Server should process documents received by the webMethods messaging trigger one after the other.
Concurrent	Specify that Integration Server should process as many documents received by the webMethods messaging trigger as it can at once.

3. If you selected concurrent processing, in the Max execution threads property, specify the maximum number of documents that Integration Server can process concurrently. Integration Server uses one server thread to process each document in the trigger queue.

4. If you selected serial processing and you want Integration Server to suspend document processing and document retrieval automatically when a trigger service ends with an error, under Fatal error handling, select True for the Suspend on error property.

For more information about fatal error handling, see Fatal Error Handling for a webMethods Messaging Trigger .

5. Click File > Save to save the webMethods messaging trigger.

Notes:

If you selected serial processing, Integration Server creates a serial durable subscription on the channels that correspond to the publishable document types to which the trigger subscribes.

If you selected concurrent processing, Integration Server creates a shared durable subscription on the channels that correspond to the publishable document types to which the trigger subscribes

Integration Server Administrator can be used to change the number of concurrent execution threads for a webMethods messaging trigger temporarily or permanently. For more information, see webMethods Integration Server Administrator’s Guide.
