COMPUTER DEVICE FOR SUPERVISING DUAL SYSTEM STATUS

摘要

PURPOSE:To speed up the switching of the titled computer even when an auxiliary storage device is used in common by detecting the last status information processed by a main system in a queued system at the failure of the main system and allowing the queued system to continue status detecting processing from the succeeding status information. CONSTITUTION:Status information is inputted both main and queued systems. When a computer in the main system stops, a computer in the queued system reads out the remote control information finally processed by the main computer which is left in a remote control information input waiting table 11 from a processed pointer 19, retrieves the same information as the read-out information from a remote control information input waiting table 17 and then starts processing from the succeeding remote control information. Consequently the computer in the queued system can continue the processing of status information immediately after switching the computer from the main system to the queued system.
