PURPOSE:To highly efficiently execute abnormality information to a queuing work program when abnormality occurs, the release of a queue and the release of exclusiveness by forming queues in a requested system and a requesting system. CONSTITUTION:At the time of executing the exclusive processing of a remote file, a working program 3 sends an exclusive request to a server system 2 through an access interface. At that time, the exclusive request is registered in an exclusive request queue 7 by an exclusive transmitter 5-1, and at the time of receiving an exclusive result, an exclusive receiver 5-2 releases the queue. On the server system 2, the exclusive request received by the exclusive receiver 5-3 is sent to an exclusive control process 6 to register the exclusive information into the exclusive control table 8. When abnormality occurs in the circuit, a client system 1 informs an error to the working program 3 based upon the contents registered in an exclusive request queue 7 and the server system 2 releases the exclusiveness and the queue based upon the contents of the table 8. Consequently, the influence of abnormality on a partial line to the stop of the whole system can be suppressed. |
