Abstract

PURPOSE:To reduce the rate of the program transfer maintenance failures due to the input/output faults caused in a maintenance updating state by initializing automatically a program store part at occurrence of an input/output fault and transferring again the program by reference to the control information in order to restore the fault. CONSTITUTION:When an input/output fault occurs, all programs containing both the program total information 1c and the program individual information 1d which are registered into the received control information 1a are received by a storage 3c from a host controller 1 via a communication link 2. Then a program store part 3b is initialized and then the received program is copied to the part 3b. Then the retrial of the transfer maintenance is carried out. If this retrial ends normally, the program control information 3a is updated into the latest state. Thus, it is possible to reduce the rate of the program transfer maintenance failures due to the input/output faults caused in a mainte nance updating state.

In the conventional technology, retrying in case of an input/output failure during maintenance is manually performed, so there is a problem in that it takes a long time to recover when a failure occurs. In addition, program transfer maintenance is often used for maintenance and operation of large-scale network systems, and because there are cases where the system operator on the terminal device side is not present when program transfer maintenance is executed, failure recovery is difficult. There is a risk that this will slow down the system and have a serious negative impact on system operation.

In the program transfer method shown in FIG. 1, the host control device 1 has program management information 1a and a program storage section 1b, and the program management information 1a has overall program information 1c and individual program information 1d. A terminal device 3 connected to the upper control device 1 through a communication link 2 has program management information 3a, a program storage section 3b1, and a storage device 3c for receiving program transfer data. The program management information 3a on the terminal side includes overall program information 3d and individual program information 3e, similar to the host control device, and the operating conditions for transfer maintenance are controlled by comparison conditions.
