METHOD FOR SETTLING COMMUNICATION INTERRUPTION IN INTER-PROCESS COMMUNICATION

摘要

PURPOSE: A method for settling a communication interruption in an inter-process communication(IPC), is provided to settle a communication interruption, without restarting a system after turning off, when a communication is interrupted by an occupancy of IPC queue resources by a special processor, in an IPC server of a real-time operation system. The method enables to continue an information process operation of other processes, by sacrificing only one or small minority of process, in an operation system held up while many processes process information. CONSTITUTION: A method for settling a communication interruption in an inter-process communication(IPC), comprises the steps of: recognizing a queue pool generation and informing a user of the generation; selecting a sacrificial process among processes existing in an operation system; collecting every queue resources from the selected sacrificial process; resuming a normal operation of the system by making the collected queue resources shared by existing processes.
