Disclosed is a technique for flow control. It is detected that a work request is being transferred to an in-memory structure. A maximum limit is compared with a number of work requests stored in the in-memory structure. If the number of work requests stored in the in-memory structure equals the maximum limit, a notification is sent that indicates that additional work requests are not to be sent.

Method, system, and program for facilitating flow control

Disclosed is a technique for system recovery. Information identifying one or more work requests is retrieved, along with an order of the work requests, for a business process. If the business process is non-transactional, an in-memory structure is created for the business process, a recovery stub is created for each work request, and the recovery stub for each work request is placed into the in-memory structure based on the order.

System recovery

The present invention provides a method for remotely activating application programs and adapters including a queue manager (QM) that monitors for predetermined trigger events (e.g., time out for messages in an application queue) and, when such events occur, generates a trigger message. The trigger message includes process information associated with the application which is used by a trigger monitor application to issue an appropriate command to the application.

Program reactivation using triggering

Disclosed is a technique for buffering work requests. It is determined that a work request is about to be placed into an in-memory structure. When the in-memory structure is not capable of storing the work request, a work request ordering identifier for the work request is stored into an overflow structure. When the in-memory structure is capable of storing the work request, a recovery stub is generated for the work request ordering identifier, and the recovery stub is stored into the in-memory structure.
