Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] In the embodiment of the present invention, when an active process is started to process service requests, a hot standby process is started, and the hot standby process directly or indirectly uses all or part of the hardware resources used during the running of the active process. When the process stops, the unprocessed service requests and subsequent service requests of the active process are transferred to the hot standby process for processing, so as to achieve high availability of the system.

[0031] In this embodiment of the present invention, an active process refers to a process that...

Abstract

The invention is applicable to the field of computer, and provides a method, a system and equipment for realizing high availability. The method comprises the following steps: starting a hot backup process when an activity process provides services for consumers; detecting the status of the activity process; and starting the hot backup process to provide services for the consumers when the status of the activity process is in a halt state. The embodiment of the invention starts the hot backup process while starting the activity process, so that a service request can be transferred timely to the hot backup process which provides services when the activity process has fault, the fault recover time is shortened, and the availability of the whole system is improved. Meanwhile, the embodiment of the invention can meet the requirement on the high availability in the presence of single server.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method, system and equipment for realizing high availability. Background technique [0002] With the continuous development of computer technology, the scale of users served by software systems is getting larger and larger, and the business activities of enterprises have higher and higher requirements for the availability of software systems. Availability refers to the degree to which the system is in a workable or usable state when it is needed and starts to perform tasks at any random moment. Reliability and maintainability jointly determine availability. The reliability is measured by the mean time between failures (the time during which a device can operate continuously without failure). Maintainability is measured in terms of the time it takes for a system to return to normal after a failure. Existing technologies such as dual-system hot backup and clustering are all...
