Abstract

PURPOSE:To prevent the system-down by performing the transfer of the information started from the district center based on the process sequence of the district center and then restarting the transfer of the information started from the satellite office to the district center based on the process sequence of the satellite office. CONSTITUTION:At the concurring time, the transfer of the information started from district center 11 is carried out based on the process sequence of center 11. For instance, when satellite office 1 decides that the information received from center 11 is to office 1 itself, office 1 operates based on the information. On the other hand, satellite office 2 and 3 decide that the information is not to them and also discontinue the information start when it is started by themselves. Thus office 2 and 3 restart the transfer of the information based on the process sequence of the satellite office after the end of the priority process sequence of center 11 and office 1. In this way, the concurring of the information is avoided to prevent the system-down of the process.
