When you suspend document retrieval for all the webMethods messaging triggers on an Integration Server, the Integration Server stops retrieving documents from the Broker and Universal Messaging. Integration Server resources, such as threads and memory, that would have been used for document retrieval are available for other tasks.

Suspending document retrieval for all webMethods messaging triggers is a quick way to free up server resources. This can be especially helpful in a situation in which the Integration Server is functioning under heavy load and additional resources are needed immediately.

Suspending or resuming document retrieval can be a temporary or permanent change. (Integration Server considers a document retrieval change to be permanent if you selected the Apply Change Permanently check box when you made the change.) If the change is temporary, Integration Server reverts to the permanent document retrieval state when Integration Server restarts or you reload a package. When you reload a package, Integration Server reverts only the webMethods messaging triggers contained in that package to the permanent document retrieval state. For example, suppose that you temporarily suspend document retrieval for all webMethods messaging triggers. If you reload the package OrderProcessing, Integration Server resumes document retrieval for the webMethods messaging triggers in the OrderProcessing package only.

You can gradually resume document retrieval by setting the Queue Capacity Throttle to a low percentage, such as 10%, and then resuming document retrieval for all webMethods messaging triggers. Integration Server resumes document retrieval at the adjusted capacity for all webMethods messaging triggers. You can also gradually resume document retrieval by selectively resuming individual triggers. For example, you might want to first resume document retrieval for those triggers that are part of a critical or high priority process.
