PROBLEM TO BE SOLVED: To speed up the recording of logs in the same recording medium by a plurality of processes.SOLUTION: In an information processing device 100, when an acceptance unit 102 detects the generation of log information by a process executed by a process execution unit 101, an assignment unit 108 assigns a log sequence number (LSN) to the log information. Furthermore, when the acceptance unit 102 requests that the assigned LSN and a process identifier that generated the log information be stored in a state holding unit 103 and the long information be recorded. When the recording of log information by a medium recording unit 105 is in progress, the acceptance unit 102 continues detecting the generation of log information. When the recording of log information by the medium recording unit 105 is not in progress, a request unit 104 generates an access request including a request LSN. The medium recording unit 105 collectively records log information requested to be recorded in a log recording medium 106. A completion waiting unit 107 sequentially awakens a process that requested the recording of log information the recording of which has been completed.SELECTED DRAWING: Figure 1 |
