PROBLEM TO BE SOLVED: To prevent the double start-up of a business system.SOLUTION: A method refers to execution history before calling out an activation object, and blocks start-up if the activation object is in execution. It records activation history for each type of processing in the order of activation start time, and confirms a situation from the latest item in the activation start time in the event of referring to the execution history. In the confirmation of the situation, it determines activation is not permitted if the latest item is activated (in processing). If processing of the latest item is already complete and activation is permitted, it compares the next item, if it is activated (in processing) at first, it determines processing is not permitted at that time.SELECTED DRAWING: Figure 2 |
