4] in normal course of operation, event periodically fault detection: is carried out to each module of software and hardware of composition computer system
Barrier detection；
5] failure logging: after finding that computer system breaks down, tentatively judging the failure of generation, record event
Hinder information；
6] failure recovery: according to the fault message of record, further screening failure, filters off accidental recoverable
Failure determines position and the type of unrecoverable failure；
7] it policy selection: according to the position of unrecoverable failure and type, is determined at failure according to the description of system blueprint
Reason strategy, if requiring system self-healing, selection can bypass the configuration item of failure；
8] configuration updates: setting can bypass the configuration item of failure as item is currently configured, which will be in system
It is loaded into system when starting next time, renewal process does not change the operating status of current failure system；
9] system is closed: after the completion of configuration updates, being closed the operation of system, is loaded updated match when waiting starting next time
Set item.
Above step 5] in record fault message mainly include failure occur time, position and type.
The present invention has the advantages that
The present invention replaces malfunctioning module from the point of view of computer system, through backup module, using in system blueprint
Current-configuration item control system self-healing procedure, realize the fault self-recovery of complex computer system, have Self healing Strategy it is simple,
The advantage that self-healing procedure is controllable, self-healing result determines.

Specific embodiment
The present invention is described in detail below in conjunction with attached drawing.
Fault self-recovery method based on system reconfiguration, applied computer system on hardware by multiple functional modules and
Backup module composition includes the modules such as fault management, configuration management, system blueprint composition on software.
System blueprint is the key Design of system failure self-healing.It includes multiple configuration items of system operation, each configuration
Item all describes the various configurations such as software, hardware, network of computer system, and computer system can be according to the description of configuration item
Operation；These configuration items further include the description to all troubleshooting strategies, these strategy include system closing, system self-healing,
It continues to run；Configuration item includes 1 fault-free configuration item and multiple fault configuration items, and fault-free configuration item describes system and exists
Configuration when fault-free, and fault configuration item utilizes certain unrecoverable failure of backup module bypath system, enables a system to
It is operated normally under the failure；In all configuration items, there is 1 meeting to be arranged to be currently configured item, can add after system starting
Carry this configuration item.
Backup module is the necessary condition of system self-healing.Some module unrecoverable failure can occurs in systems in it
When, instead of the work of the module.
As shown in Figure 1, whole system is interconnected by multiple modules, input-output unit by communication network, pass through branch
The middleware for holding system self-healing realizes the fault self-recovery of system according to the description of system configuration file.Systematic difference operates in
In processing module, the input and output of application are completed by input-output unit.The module of system is by multiple functional modules and backup
Module composition, under the action of middleware, when unrecoverable failure occurs for some module in system, backup module can be replaced
The work of the module.
Critical process of the invention is as shown in Figure 2.Firstly, in system operation, after detecting system jam,
Failure is positioned and is filtered, judges fault type；Secondly, the strategy of self-healing is selected according to fault type, by working as system
Preceding configuration item is updated to that the configuration item of failure can be bypassed；Finally, system is according to new current-configuration item after system restarting
Work, system function self-healing.
Middleware is the moulds such as critical software, including fault management, configuration management, system blueprint that system self-healing function is realized
Block, by the way that system starting, configuration load, fault detection, failure logging, failure recovery, policy selection, configuration update, system is closed
Close and etc., realize the self-healing of failure, as shown in Figure 4.It is described as follows:
1] system starts, and completes the initialization of each module software and hardware of system during the system startup process；
2] configuration loads, current-configuration item described in configuration management function loading system blueprint to computer system
In；
3] system is run, and computer system operates normally or close system according to the description for being currently configured item；
4] fault detection, in normal course of operation, fault management capability is regular to each module of composition computer system
Carry out fault detection；
5] failure logging tentatively judges the failure of generation after finding that computer system breaks down, and records event
Time, position, type of barrier etc. are used for system maintenance, accident analysis；
6] failure recovery is implemented to screen, filters off accidental recoverable failure to the failure of generation, determines irrecoverable event
The position of barrier and type；
7] policy selection, according to the position of unrecoverable failure and type, it is suitable to select according to the description of system blueprint
Processing mode or reconstruction strategy；
8] configuration updates, and setting can bypass the configuration item of failure as item is currently configured, which will be in system
It is loaded into system when starting next time, renewal process does not change the operating status of current failure system；
9] system is closed, and according to the operation of set instruction closing system, waits starting next time.
