Abstract
The invention provides a dual-module hot standby method and system for spliced screens, wherein states of optical engines are timely switched through establishing a connection between two optical engines. When having failure at an active state, one optical engine is switched into a malfunction state, and the other optical engine at a standby state can be timely switched into the active state. The invention ensures that the standby optical engine can be switched into the active state when the active optical engine has a failure even if a main host has a failure or is shut down, and thus reliability and automaticity of dual-module hot backup are enhanced.
Description
Technical field
The present invention relates to the two-node cluster hot backup field, relate in particular to the high combination of a kind of stability with double hot standby method and system.
Background technology
Two-node cluster hot backup is refered in particular to based on the heat of the two-server in the high-availability system and is equipped with (or high available), and to can be used on domestic use more because of two machine height, so the two-node cluster hot backup of gaining the name.Two-shipper high available be divided into by the switching mode in the work main-be equipped with mode (Active-Standby mode) and two host modes (Active-Active mode): main-mode refers to a station server to be in certain professional operating state (be state of activation fully; The Active state), another station server is in this professional stand-by state (being the Standby state); Two host modes promptly refer to two kinds of different business activestandby state (being Active-Standby and Standby-Active state) each other on two-server respectively.
With the combination system, 7 * 24 hours high reliability is indispensable characteristics for monitoring.In order to improve the reliability of combination system, adopting two-node cluster hot backup is more common means.That combination mainly adopts with Dual-Computer Hot-Standby System is main-be equipped with mode; The Dual-Computer Hot-Standby System of combination employing at present; Operation principle is following: each unit in the combination is by being made up of two ray machines; Promptly first ray machine and second ray machine are set up the TCP communication with every ray machine during main control system PC startup and are connected.When system moved, first ray machine in the unit was in running order, and second ray machine is in stand-by state (promptly second ray machine starts fully, but does not light), to guarantee that when first ray machine broke down, second ray machine can be launched rapidly.Break down at first ray machine; During like the decay of color, brightness or part operation irregularity such as fan, power supply, first ray machine will through with main control system PC between TCP be connected and notify main control system PC fault message, main control system PC is behind the fault message that receives first ray machine; Light order through issuing to second ray machine with being connected of second ray machine; Make second ray machine get into operating state, the fault message with second ray machine is prompted to the user simultaneously, notifies it to keep in repair.
Said system work is simple; But aspect reliability, still there is following shortcoming: first; If main control system PC breaks down or is in off-mode, then first ray machine can't be notified its fault message to main control system PC, thereby can't make second ray machine get into operating state automatically; The second, after the first ray machine reparation finished and powers on, main control system PC can't connect with first ray machine automatically, so when second ray machine breaks down, can't switch to first ray machine, makes first ray machine get into operating state automatically.Above-mentioned shortcoming makes prior art have certain stable hidden danger, needs to adopt new double hot standby method to solve the two-node cluster hot backup problem, to improve the stability of combination with Dual-Computer Hot-Standby System.
