Processing sequence control apparatus, processing sequence control method, and processing order control program

摘要

PROBLEM TO BE SOLVED: To facilitate update of a system that sequentially executes a plurality of processing continuously.SOLUTION: A control process for controlling execution sequence of a plurality of processing that one or a plurality of processes that operate on one or a plurality of computers execute locks the control process and a predetermined storage area included in storage means accessible by the process. Then, the process requests lock for a portion corresponding to the execution sequence of the plurality of processing in the storage area where the control process has locked. In addition, the control process sequentially releases lock of the portion required for lock by the process while making the execution sequence of the plurality of processing correspond to the portion. When the required lock can be executed, the process executes processing corresponding to the portion.
