<P>PROBLEM TO BE SOLVED: To shorten a period required for restoration by this system. Ž<P>SOLUTION: In a duplex processor system, each of an active system processor and a standby system processor includes a CPU and a main memory, and when a fault occurs in the active system processor, a restart activation means is activated and a restart method according to a fault factor is selected. In the duplex processor system which performs restart activation, the restart activation means includes a memory restoration means which performs restoration, when detecting an error which is not corrected with an error correction and detection code of data read from the main memory of the active system processor, by reading this data from the main memory of the standby system processor and writing it in the main memory of the active system processor, and performs restart activation by selecting the restart method according to the fault factor after restoring the data of the main memory of the active system processor with a memory restoration means.
