Abstract

PURPOSE:To obtain a system which has the less probability that an erroneous value is transferred, by maintaining the excellent real-time characteristics of memory transfer between computers, by providing a data base equivalency part and a data base copying part in a doubling controller. CONSTITUTION:In a doubling controller 3, a data base equivalency part 33 is provided to receive the rewriting address of a memory 12 when an actual- operation side computer 1 rewrites data, utilized in common by two computers, in its own memory 12 and also to transfer the data in the address from the memory 12 of the said computer 1 to the memory 22 of a stand-by side computer 2. Further, a data base copying part 34 is also provided which operates in parallel to the equivalency part 33 and transfers the data base in the memory 12 of the computer 1 to the memory 22 of the computer 2 at least in the initializing stage of the computer 2.
