Realization of Fault-tolerant Technique in Distributed Multi-layer System
Zhen Li · Modern Electronic Technique · 2005
In distributed multilayer system, we distribute application server in two or more computers, according to load balancing, client application can connect with one of application servers and ask for services If the application server fails and can't keep providing services Under the help of Agent, client application can link to other application server running in other computers and ask for services If all the computers running application servers fail, client application can save updating data, when the computers failed come back to normal states, client application write the saved data back to the remote database automatically, so the fault tolerance of distributed multilayer application system is improved greatly.
