DATA BASE IDENTIFICATION SYSTEM FOR DUPLEX PERSONAL COMPUTER SYSTEM AND PROTECTIVE RECOVERY SYSTEM FROM TROUBLE

摘要

PURPOSE:To enable a subordinate personal computer side to perform a data gathering process as a substitute when trouble occurs to a main personal computer side in a data base identification state. CONSTITUTION:Various inspection data are gethered to the main personal computer 1 through each terminals 5, but when the personal computer 1 and subordinate personal computer 3 perform specific processes automatically corresponding to events except in trouble occurrence, the personal computers 1 and 3 can identify a data base at all times. When the terminals 5 are switched to the personal computer 3 in case of trouble occurrence on the side of the personal computer 1 and the personal computer 3 operates as a substitute for the personal computer 1, the personal computer 3 serves as the main personal computer thereafter.
