High-speed restart method, information processing device, and program

摘要

Process information saving unit 131 and process restoration unit 132 are provided. A process table 201 and other information required for restoring a process present in an OS 130 are copied in a save area 124 on a main memory area 120 during execution of an application. At the restart, only the OS is initialized while leaving the main memory area used by the application as it is. After the initialization, the saved process information (the process table and other information managed by the OS) is rewritten on the OS data area 12. By employing this configuration, provided is an environment allowing the process before the restart to be continuously operated after the restart.

1. A rapid restart method comprising:
copying, before restart of an OS loaded on a main memory area of a main memory device, process information to one or more save areas on the main memory device, the OS generating the process information that comprises a process condition of one or more user processes in accordance with execution of the one or more user processes to manage the one or more user processes, and the one or more save areas being previously created in accordance with a number of the one or more user processes; initializing, at the restart of the OS, the main memory area of the main memory device used by the OS while not restarting the one or more save areas used by the one or more user processes; and restoring the copied process information from the one or more save areas to the restarted OS loaded on the main memory area after completion of the restart of the OS.
