Abstract
A technique for identifying a fundamental cause of a system fault in a system in which a plurality of OSs run on one computer. In a system in which each of a plurality of operating systems executes a process by time-sharing hardware of one computer, a plurality of related OSs are stored in advance in association with each other, in a storage means. When a fault is detected in an OS and the storage means stores an OS associated with the OS in which the fault has occurred, a memory dump is performed for the OS in which the fault has occurred and the OS associated with that OS.
