System, method and computer program product for dynamically changing message priority or message sequence number in a message queuing system based on processing conditions

摘要

A message sequence number or message priority level stored in a queue maintained by a message queuing system may be dynamically changed based on processing conditions by the use of a message sequence regulator (MSR) system. The MSR system includes a message parser, a message extraction repository, a rules repository, a message definition repository, an interface to a resource monitor for monitoring system resources by single resource monitoring agents, and a notification component for identifying sequence regulation operations which cannot be executed. The MSR system receives copies of messages loaded into or retrieved from queues by a queue manager as well as event messages from the resource monitor. The message extracts parts of the message using message structures defined in the rules repository and stores the extracted parts in the message extraction repository. If a defined condition is found to exist, the MSR system initiates calculation of an appropriate message sequence number or message priority level. The queue manager updates the message record without removing the message from the queue.
