| Abstract: | A backup technologies in moment use was analyzed. Hot backup mechanism with multi server was designed, and a voting arithmetic was given. The multi application and multi database servers were operated cooperatively, and the stabilizability and credibility of the application system ensured. This system has been used to the Wuhan Fire Communication and Command System. The stability and reliability of the system are proved. |
