PROCEDURE CALL PROCESS SUBSTITUTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To actualize fault resistance and load dispersion by the multiplication of a procedure execution side and to improve the reliability and performance of procedure call process substitutive system by selecting an execution result according to a specific selection logic. SOLUTION: A remote procedure call(RPC) process part 12 determines the positions of procedure execution parts 20-23 which execute RPCs requested by a procedure request part 10 by using a procedure directory 13. A logic directory 15 is used to determine the execution number and execution order of the procedure execution parts 20-23, and also determine which of procedure execution results received from the respective procedure execution parts 20-23 is returned to the procedure request part 10. Logic used for this determination is selected out of a selection logic function directory 16 and a call logic function directory 17 and registered in the logic directory 15 based on the instruction from a user.
