Realization of persistency for meeting scheduling system based on mobile agent technology

We are developing a meeting scheduling system based on mobile agent technology. This system accesses to users from system side by the agent´s autonomous operation. Moreover, this system negotiates rescheduling based on sharing information by the communication between agents. This system exists the scheduling server at the center of all agents migrate. The previous system had to constantly keep it running, because of agents migrate irregularly between the scheduling server and user´s hosts. If the scheduling server is stopped, moving agents were lost on this system, and agents in user´s hosts cannot migrate to other hosts. These wrong actions lead information´s inconsistency. In this study, we implemented the function to stop the system temporarily, and the system support stopping the power supply for maintenance, etc. Therefore, a scheduling that stepped over the period when the power supply stopped became possible.
