Application service operation processing system based on multi-machine hot backup

Abstract

The invention provides an application service operation processing system based on multi-machine hot backup. On the basis that the multi-machine hot backup is adopted, according to the communication control and the switching on-line operation strategy between a plurality of application program operation units and a plurality of service database units, the application program operation units subjected to on-line operation do not need to directly participate in hot backup data processing, the processing performance of the application service, which is outwards provided by the application program operation units, is guaranteed; only when each service database unit in the system obtains that the operation state of the application program operation units subjected to on-line operation is abnormal, the active / standby switching of the application program operation units is triggered; the possibility of the operation of switching by mistake is greatly lowered; the application program operation units and the service database units can be independently subjected to active / standby switching; the transition of the active / standby switching is smoother and quicker; and the application service operation switching smoothness and stability of the multi-machine hot backup system can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of communications and network application services, in particular to an application service operation processing system based on multi-machine hot backup. Background technique [0002] With the development of science and technology, the application of computer systems has become more and more extensive, and the reliability requirements of computer systems are quite high in many application fields. If the computer fails, it may lead to many serious consequences. In some special application fields, it will not only bring various economic losses, but also seriously endanger people's lives. Fault-tolerant technology is one of the most powerful means to build a high-reliability computer system. It refers to the technology that maintains the normal operation of the system when computer software and hardware have abnormal behavior due to physical implementation, environmental impact, operational errors or design de...
