PROCESS ABNORMALITY DETECTION SYSTEM

摘要

PURPOSE:To prevent a resource in a decentralized control information interchange system from being held ineffectively by detecting a state dissidence between processes due to a communication failure state which occurs in a call process in its early stage. CONSTITUTION:If the communication failure state occurs between information processors A and B in a transfer process of data (c), a process P0' in the processor A sends out a disconnection request signal to a circuit L0. When a disconnection confirmation signal arrives from the circuit L0, the processor P0' is ceased. On the other hand, a process P1' in the processor B sends a reception ready signal to the process P0' and then detects a communication failure state because no reception ready signal is returned from the process P0', so a disconnection request signal is sent out to a circuit L1. The process P1' is ceased after a disconnection confirmation signal is returned from the circuit L1.
