    摘要： An XLANG/s compiler detects convoy scenarios during compilation and generates runtime directives to correctly correlate incoming messages with business process instances. A convoy scenario, present in event driven processes, is defined by a correlation set initialized during a receive operation which is provided to a subsequent receive operation. The compiler detects those convoy scenarios by analyzing the control and dataflow of a XLANG/s program. Three convoy patterns are distinguished: (1) activation convoys, (2) uniform sequential convoys, and (3) non-uniform sequential convoys. XLANG/s allows declarative descriptions of convoy scenarios without requiring an understanding of the low-level details supporting their correct execution. Convoy scenarios are processed by statically analyzing a written workflow application to deduce the nature and type of convoy scenarios used by the application. Information is extracted at compile time to support the runtime infrastructure. The runtime infrastructure is tightly integrated with the underlying correlation and subscription evaluation framework.

    摘要： A transport-neutral in-order delivery in a distributed environment is provided. Typically, in-order delivery guarantees that sequential orders received by a transport engine are sent out in the same order they are received. Such delivery may be forwarded either to another transport engine or to some application. In case there is a failure of delivery of messages in a stream, the messages are either resubmitted, suspended, or moved to backup. A user or administrator can configure the desired action. Additionally, any stream can be manually aborted or a specified port can be unenlisted. Deliverable streams of messages are locked on to a back-end transport engines or applications and dequeued sequentially unless one of the above mentioned failure scenarios occurs.

    摘要： Methods for providing dynamic process recovery that supports recovery of event driven services. The present invention addresses situations where a service-hosting process fails as well as all of the services which were running in that process. To recover from this scenario, the present invention restarts the services a different process from a last know good state. The present invention also provides for situations where a process is shut down in a controlled manner, but the services running within it are still able to drive. Here again, the services are restarted in a secondary process. The recovery modal described here, therefore, advantageously addresses a problem in the design of a distributed event-driven environment.

    摘要： Systems and methods for controlling the work load on a distributed system comprising a plurality of stages are provided. The capacity of a present stage is monitored, using either various resources of the present stage or rates of work completion and work receipt of the present stage. Information indicating the capacity of a succeeding stage are obtained and communicated to the present stage. The monitored capacity information of the present stage and the communicated information of the succeeding stage, either alone or in combination, are used to determine if a throttling action is necessary to control the load of work at the present stage. A provided throttling technique inserts an appropriate delay before the present stage to allow the present stage to process an amount of work without saturating the capacity of the present stage. This technique is applied at each stage of the distributed system to control the work load of the overall system by controlling the work load at each stage.
