PURPOSE:To effectively use system resources by providing a phase control table showing the control state of phase information in respective transaction processes and controlling a generation in a phase information storage area. CONSTITUTION:A phase control means 20 checks whether a transaction process 102 is writing second generation phase information in a transaction process 101 by using the phase control table 30. When the writing of second generation phase information is not completed in the process 101, the process 102 waits for the completion of the writing of second generation phase information. When the writing of phase information completes in the process 101, the process 102 declares that second generation phase information in being written to the table 30 and writes second generation phase information in the process 102 into the phase information storage area 41. The flag of the table 30 which is raised in a previous step is eliminated here, and a processing terminates. Thus, the system resources can effectively be used. |
