<P>PROBLEM TO BE SOLVED: To avoid the possibility that a restarted OS fails due to the same factor again by detecting the failure of an OS in operation, and calculating an OS control parameter as the solution of the factor of the failure. <P>SOLUTION: A computer system having a means for restarting the same OS or the same type of OS when the execution of an OS in system operation can not be continued is provided with: a means for detecting the failure incapable of the continuity of the operation by a means for analyzing its own load status or failure and by a failure monitoring means; and a means for specifying a kernel control parameter item and value for solving or avoiding the circumstances. When the specified parameter includes a static control parameter, the specified parameter is designated, and the same OS or the same type of OS is restarted. When the specified parameter is a dynamic parameter, the restart of the OS is not operated, and it is applied to the OS in operation. Also, when the OS is restarted according to the instruction of a manager, the optimization parameter specified so far is applied to restart the OS. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
