DISTRIBUTED TELEGRAPHIC MESSAGE PROCESSING SYSTEM

摘要

Telegraphic messages inputted from external terminals through a communication line are processed in a distributed manner in a plurality of telegraphic message processing devices (10a) as shown in the figure. The common resources in a storage unit (data base) (14) are updated on the basis of the results of this processing operation. Each of the telegraphic message processing devices (10a) is provided with a lock sequence determination unit (15) and a lock processor (16), and lock requests for resources common to the subject devices or other devices, which are issued by the subject devices, are sorted, arranged in predetermined order common to all the devices and issued sequentially, the outputting of subjecting lock requests being held until the lock processing based on precedent lock requests has been finished. Each device is provided in its telegraphic message processing unit (13) with an autonomic telegraphic message assurance member (133) which removes the causes of abnormality, in the event of a failure in updating in the subject device, and execute the updating process autonomically. This system is formed so as to improve a general system processing efficiency while preventing the occurrence of contradiction of the common resources to one another.
