PROBLEM TO BE SOLVED: To provide a patch processing technology suitable for a system where the operation configurations of a server coexist. SOLUTION: This server system is provided with an active system server device (110) for executing a process (150); a duplex unit (101) equipped with a standby system server device (120) which is put in a standby status for an alternative operation for the active system server device; a simplex unit (102) equipped with a server device (130) for executing the same process (150) as the above process; and a maintenance server device (140) connected to each server device of both the units. The maintenance server device transmits the patch data (141) for correcting the process to the simplex unit and the duplex unit. The standby server device notifies the operation system server device of the success/failure of patch processing. The operation system server device decides the content of notification from the standby server device, and executes the patch processing of its own device from the patch data when it indicates the success/failure of the patch processing.
