STATIC MESSAGE PLACEMENT IN QUEUES BASED ON AN APRIORI DEFINED PLACEMENT PLAN

摘要

An information exchange between at least two processes (FEED_PROC-1, FEED_PROC-2, CONSUME_PROC-1) communicating with each other using at least one queue (QUEUE-001) uses a placement plan for determining the order in which messages are placed into the queue. The information feeding processes (FEED_PROC-1, FEED_PROC-2) place pieces of information (MESG-001, MESG-002) into the queue (QUEUE-001), from where an information consuming process (CONSUME_PROC-1) sequentially consumes the pieces of information. The placement plan describes, for at least one possible value of identifying information contained in each of the pieces of information, a respective position (POS-001, POS-002) in the queue (QUEUE-001), such that the pieces of information (MESG-001, MESCG-002) or respective references thereto are placed into the queue according to positions in the queue (QUEUE-001) corresponding to the respective values of the identifying information in the pieces of information.
