METHOD FOR PREVENTING DATA LOSS AT SWITCHING MAIN PROCESSOR IN OPERATION AND MAINTENANCE PROCESSOR OF DUAL COLTROL SWITCHING SYSTEM

摘要

PURPOSE: A method for preventing data loss is provided to make a normal message displayed at a user MMC terminal at switching an operation and maintenance processor into a main processor. CONSTITUTION: A method for preventing data loss is described in which an operating system of an MP applies an interrupt signal(S_TAKE_END) to SCIC in response to a standby drive command from a user processor(300,302). The operating system delays an operation for clearing a write_pointer value of an input/output driver so that data stored in a DRAM in the SCIC is displayed at a user MMC terminal(304). The SCIC transfers and displays display information requested by a user and remaining in the DRAM, and applies an interrupt signal to the operating system when all information in the DRAM is transferred. The operating system stores data related to an input/output driver in the DRAM by a predetermined format(306). The data of the input/output driver is copied to a DRAM of the MP at a standby side(308). The operating system operates at a standby mode(310).
