PROBLEM TO BE SOLVED: To shorten the restarting processing time of a computer where a fault occurs and to considerably reduce a load to the other normal computer by settling an operation against a common resource in a process by an execution system processing where the fault occurs by means of a computer except for the computer where the fault occurs. SOLUTION: When a fault occurs in the execution system processing function 11 of a computer 1, a fault communication management function 13 detecting the fault is started in the computer 1. The fault communication management function 13 decides the computer of a request source requesting a settlement processing on a common resource 61, starts an execution system processing function resumption start processing at a mutual restoration mode and requests a common resource settlement processing to the mutual restoration system processing function 25 of a computer 2. In the normal computer 2, the mutual restoration system processing function 25 executes the common resource settlement processing settling a processing in a process against the common resource 61 and it can use the common resource 61 from the other normal execution system processing function 31 when it receives a common resource settlement processing request communication from the computer 1. |
