Abstract
The present invention is a kind of computer system fault tolerance method, is comprised the step of：(1) dual system cold standby：When working machine failure, the backup machine being not powered on starts and takes over work automatically, and fault diagnosis and maintenance are carried out to working machine；When pending fault reparation finishes, working machine goes electricity to become guest machine.(2) dual system warm standby：Two-shipper is simultaneously powered up, machine work, and another machine, which is in, to be waited.When working machine failure, system will be automatically switched, and take over work by warm standby machine, and failure machine is diagnosed and repaired；When pending fault reparation finishes, working machine becomes warm standby machine.A kind of computer system fault tolerance method of the present invention, ensure that the computation error to be happened suddenly in operation will not cause the failure of whole system using substantial amounts of fault-toleranr technique.
Description
Technical field
The present invention relates to computer system fault tolerance field, more particularly to a kind of computer system fault tolerance method.
Background technology
Fault-toleranr technique refer to when system operationally it is wrong be activated in the case of uninterrupted offer service is be provided
Methods and techniques.Cured in some particular applications, such as Aero-Space, national defense and military, nuclear energy electric power, industrial chemical, health
The key sectors such as first aid are treated, one time computer system errors this may result in irremediable massive losses, at these
It must ensure that it is whole that the computation error to be happened suddenly in operation will not cause using substantial amounts of fault-toleranr technique in the design of critical system
The failure of individual system.
The content of the invention
The present invention is to overcome the above insufficient, there is provided a kind of computer system fault tolerance method, is comprised the step of：
(1) dual system cold standby：When working machine failure, the backup machine being not powered on starts and takes over work automatically, to work
Machine carries out fault diagnosis and maintenance；When pending fault reparation finishes, working machine goes electricity to become guest machine.
(2) dual system warm standby：Two-shipper is simultaneously powered up, machine work, and another machine, which is in, to be waited.When working machine failure,
System will be automatically switched, and take over work by warm standby machine, and failure machine is diagnosed and repaired；Pending fault reparation finishes
When, working machine becomes warm standby machine.
(3) dual system is hot standby：Two-shipper is simultaneously powered up, and is in working condition, and simply the result of hot standby machine is not defeated
Go out.Once attended computer breaks down, attended computer is changed, carries out result switching；When pending fault reparation finishes, working machine becomes hot standby
Machine.
(4) dual system duplex：Two-shipper is simultaneously powered up and work, result export simultaneously, is compared consistent rear output.
The beneficial effects of the invention are as follows：
A kind of computer system fault tolerance method of the present invention, ensure to happen suddenly in operation using substantial amounts of fault-toleranr technique
Computation error will not cause the failure of whole system.
Embodiment
It is described in detail below with reference to embodiments of the invention.
A kind of computer system fault tolerance method, is comprised the step of：
(1) dual system cold standby：When working machine failure, the backup machine being not powered on starts and takes over work automatically, to work
Machine carries out fault diagnosis and maintenance；When pending fault reparation finishes, working machine goes electricity to become guest machine.
(2) dual system warm standby：Two-shipper is simultaneously powered up, machine work, and another machine, which is in, to be waited.When working machine failure,
System will be automatically switched, and take over work by warm standby machine, and failure machine is diagnosed and repaired；Pending fault reparation finishes
When, working machine becomes warm standby machine.
(3) dual system is hot standby：Two-shipper is simultaneously powered up, and is in working condition, and simply the result of hot standby machine is not defeated
Go out.Once attended computer breaks down, attended computer is changed, carries out result switching；When pending fault reparation finishes, working machine becomes hot standby
Machine.
(4) dual system duplex：Two-shipper is simultaneously powered up and work, result export simultaneously, is compared consistent rear output.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
Claims (1)
- A kind of 1. computer system fault tolerance method, it is characterised in that comprise the step of：(1) dual system cold standby：When working machine failure, the backup machine being not powered on starts and takes over work automatically, and working machine is entered Row fault diagnosis and maintenance；When pending fault reparation finishes, working machine goes electricity to become guest machine.(2) dual system warm standby：Two-shipper is simultaneously powered up, machine work, and another machine, which is in, to be waited.When working machine failure, system It will be automatically switched, work taken over by warm standby machine, and failure machine is diagnosed and repaired；When pending fault reparation finishes, work Become warm standby machine as machine.(3) dual system is hot standby：Two-shipper is simultaneously powered up, and is in working condition, and simply the result of hot standby machine does not export.One Denier airliner breaks down, and changes attended computer, carries out result switching；When pending fault reparation finishes, working machine becomes hot standby machine.(4) dual system duplex：Two-shipper is simultaneously powered up and work, result export simultaneously, is compared consistent rear output.
