Description

Method of Self-Diagnosis and Self-Restoration of System Error and A Computer System Using The Same}

The present invention relates to a computer system having a system failure self-diagnosis / recovery function and a method thereof.

According to the related art, as shown in FIG. 1, an operating system (eg, Windows) of a computer system detects a failure occurring while the computer system is operating (101, 102) and generates a message in case of a device failure. If the program is disabled, the program is terminated without generating a general protection fault (GPF) or solving the problem (103, 104). In such a situation, if the user fails to properly recover the failure, the failure may develop into a catastrophic failure of the entire computer system, and in some cases, the hard disk may need to be formatted or newly replaced.

In other words, the above-described conventional technology does not have the ability to monitor the problem and recover the problem when the problem occurs, and the problem remains until the entire system is shut down or restarted, which has a significant effect on the system. (105).

On the other hand, if the user does not know how to recover when a failure occurs in the computer system, the user requests a service from the service center. The service center then accepts this and sends the after-sales engineer to the user, who then checks the user's computer system and repairs it.

By the way, according to the conventional method, even if the failure of the computer system is a very minor failure, after-sales service personnel must visit the place where the computer system is located, and if the number of failures of the computer system is large, it is difficult to timely perform after-sales service. Thus, recovering from a failure in a computer system requires a great deal of time and money for the user. In addition, there may be differences in the quality of services depending on the capabilities of the service personnel.

Therefore, in the event of a failure of a computer system, not only can you recover the failed computer to its normal state quickly and easily without any additional service costs, but also detect the problem as soon as it occurs, notify the user, and analyze the cause of the problem. In order not to affect the system, there is a need for a method for allowing a user to easily recover from a failure of the computer system or to return to a previous state of the computer system.

In addition, in a specific method of implementing a computer system having a failover function, when a system file is changed, the entire system is recognized as a change, and a method of restoring it to a previous state in the form of a full recovery is a time required for failback. It takes a lot of time and the problem that the entire system is changed, so a method that can recover from the failure while avoiding the above method is required.

The present invention proposed to meet the needs as described above, in the event of a failure of the computer system, not only to recover the failed computer quickly and quickly to the existing normal state without additional service costs, but also to detect the problem immediately upon the user The purpose of the present invention is to provide a self-diagnosis / recovery system and method for notifying other users and analyzing the cause of the problem so as not to affect other programs.

Another object of the present invention is to provide a self-diagnosis / protection system to prevent recovery of time and change of the entire system by detecting and recovering only system files that are changed or upgraded by always protecting the system files. It is to provide a recovery system and method thereof.

Characterized in that it comprises a step.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A computer system having a self-diagnosis and recovery function according to the present invention is a personal computer (PC), for example, a desktop PC or a notebook PC, and the operating system operating in the computer system is Windows 95/98/2000 / Includes NT.

2 is a diagram illustrating an embodiment of a system failure self-diagnosis / recovery system according to the present invention.

As shown in FIG. 2, the computer hardware system of the present invention includes a control unit 21, a main memory device 22 connected to the control unit 21 through a system bus, an auxiliary storage device 23, an input / output device 24, CD-ROM 25 and peripheral device 26 are provided.

The auxiliary memory device 23 is a storage location for storing programs and data files for loading and executing the main memory device 22, such as a hard disk driver, a floppy disk driver, and a tape driver.

The CD-ROM 25 is used when an unrecoverable failure occurs by using state information and diagnostic information previously backed up to a computer system, or when a user wants to newly install an operating system and an application program of the computer system. .

However, since the computer hardware environment having the configuration as described above is only a technique well known in the art, detailed description thereof will be omitted herein.

However, in the auxiliary memory device 23, when a computer system is damaged due to a change in a system file or the like, it is possible to quickly and easily recover a computer in which the failure occurred to an existing normal state without a separate service cost, and to detect the problem immediately. The system file protection unit, which is a computer program for informing the user and analyzing the cause of the problem so as not to affect other programs, is stored, and is loaded into the main memory device 22 when the computer system is loaded. It operates under the control of.

The present invention provides a method of operating a separate system file DB and protecting the system file of the operating system based on this in case the system file is automatically or manually changed or the system file is missing. When the system file is upgraded, it checks its normal operation and if it is stable, it configures new information in the upgraded state and protects the system from that time, and backs up, detects, diagnoses, and recovers the DB. It is provided with a system file protection unit which is composed of a module.

That is, the system file protection unit stores a system file before and after the system file is changed in a system file DB, a system file backup unit 221, a diagnosis unit 222 for diagnosing a failure of a system file, and recovers a system file in which a failure occurs. It includes a recovery unit 223, an installation management unit 224 for detecting this when installing the application program to create an uninstall file, and a detection unit 225 for detecting the change of the system file.

This system has two functions, diagnosis function and recovery function.

The recovery function eliminates the problems of system configuration, such as resource conflict, abnormal environment variables, or restores the system to its normal state. In addition, it checks the file configuration of the hard disk and improves the performance of the system.

The diagnostic function detects the occurrence of a system failure while executing an application program and informs the user to take an appropriate response and protects the user's data. It is executed at system boot time, and resides in the form of "Tray Icon" to diagnose programs executed in the system.

When performing the system diagnostics, the system utilizes the characteristics of the operating system (OS) to enable system resources, system files, registry, and various devices (for example, HDD, Mouse, Audio, Video) that Windows has after running Windows. , Modem, etc.) and saves the information of various application programs already installed in Windows at the time of Windows booting and inspects them as Background Job.

When performing the system recovery function, the system checks system resources and system files, registry, various devices (e.g. HDD, Mouse, Audio, Video, Modem, etc.) while using Windows and various application programs already installed in Windows. Self-wizard will change the priority in the form of "TOP MOST Windows" and display a message that the user has a problem. If the user wants to do this, the user can restore the data and drivers to the original state by using the saved data at the same time as booting, reboot, and return to the previous state.If not, remove the message and back to the background job. Go back and continue to check the system.

Also, when recovering, ask the user what level (Windows, Driver, Application) to restore and proceed accordingly. Also, the Windows CAB file and the provided System Utility CD and Recovery ) Use a CD.

This system is executed in Hidden / Background / TOP MOST Windows method under Windows environment and does not affect system performance by using Kernel's Application Programming Interface (API). The function of each component is as follows.

The system file backup unit 221 may include a device state (device operation and drive version), an operating system state (window system file and system file version), and an application state (configuration file for all installed applications). In particular, the system information of the system file is backed up before the system file is changed and after the system file is changed in association with the detection unit 225 detecting whether the system file has been changed.

Reasons for the change of the system file include the system file itself or the installation of an application program or when the user inadvertently touches the system file, such as when the system file is automatically or manually changed or the system file is missing.

In order to protect the computer system mainly on the system file which is the object of the present invention, various information about the system file is obtained. This information includes the internal name, language, original file name, product name, company name that the system file has in common. Get the above information by directly accessing system file about program header, date of creation, etc., and make DB for various system files by using this information and system file comparison method. When it is done, it is used to recover.

4 shows specific components of the system file backup unit 221 as described above and the functions of each component.

The system file backup unit 221 includes a system information checking unit 410, a system file analyzer 420, a system file compression unit 430, and a system file DB 440.

In order to back up the system files for the protection of the system files, the system information grasping unit 410 first analyzes the components of the system files for each directory during the OS installation, and also stores these system files by location. Analyze by function, form, directory structure, and module.

Next, the system file analyzer 420 configures fields of an internal name, a language, an original file name, a product version, a product name, a file size, a program header, and a creation date of the system file, and forms a table structure.

Next, the system file compression unit 430 compresses the file of the information generated using the system information grasping unit 410 and the system file analyzer 420 by using a separate compressor method, Save it in a form that you can use to restore from a link.

The location where the compressed information file for the system file is stored is stored in a non-DOS area rather than an existing FAT or FAT32 area. By doing so, the user cannot access this area, and only the recovery unit 223 of the present invention can access this to use the system recovery function.

The system file DB 440 stores the information or file generated in the above process. That is, it stores system files, file information, encrypted information according to analyzer results, location information of each file, and the like.

The diagnostic unit 222 may diagnose a device (device setting, registry setting, initialization (INI) file, driver version / damage check), OS diagnosis (Windows related system setting, registry, INI, OS file check), application diagnosis (all installed Perform diagnostics (ie registry, INI, related dynamic link library (DLL), check of configuration files, etc.) for the application.

The recovery unit 223 recovers a device (recovering a corresponding fault after diagnosis) (that is, recovering a device setting, a registry setting, an INI file, a driver, etc.), recovers an OS (recovering a corresponding fault after a diagnosis) (that is, a Windows system setting, It performs the functions of registry, INI, system file recovery, etc., application recovery (diagnostic recovery after installation of all installed applications) (ie registry, INI, related DLL, configuration file recovery, etc.).

The installation manager 224 performs a function of generating an application program uninstall (that is, removing a program installed by an uninstall file generated by monitoring) when an application program is installed (that is, after the program installation is monitored and the uninstall file is generated).

The detection unit 225 automatically or manually changes the system file by upgrading the system file itself, installing an application program, or inadvertently touching the system file with respect to system files such as VXD, DLL, and SYS. It detects when a system file is missing.

For example, when installing an application program, the function of each component of the system failure self-diagnosis / recovery system will be described in more detail as follows.

The system file backup unit 221 receives the optimal previous system environment information before installing the program. In addition, the current system environment information is stored when the system is shut down.

The detection unit 225 detects a change in the system file according to the installation of the application program, and the installation management unit 224 associated with this generates an uninstall file when the program is installed.

The diagnosis unit 222 diagnoses an abnormal state of the current system based on the current system environment information, informs the user of the detected abnormal state, and the recovery unit 223 generates the installation manager 224 according to a user's request. It executes the uninstall file and removes the installation program detected abnormally and automatically restores the normal environment of the system before installing the program.

The system files are changed by the user changing the system files by accidentally deleting or modifying the system files such as VXD, DLL, SYS, or by changing the system files by upgrading the system files themselves. In addition, the function of each component in case of system failure is as follows.

First, the system file backup unit 221 backs up the system information on the system file before the system file change, and the detection unit 225 detects the change of the system file due to the respective causes, and receives the fact of detection in association with this. One system file backup unit 221 backs up the system information each time a system file is changed, the diagnosis unit 222 diagnoses a failure of the system, and then the recovery unit 223 according to the user's selection Whenever changes are made, restore the system to the desired level of each backed up system information.

3 is a flow chart of an embodiment of a system failure self-diagnosis / recovery method according to the present invention.

As shown in FIG. 3, in the system failure self-diagnosis / recovery method according to the present invention, when Windows is first booted (301), the previous system information is backed up and the system file is installed for reasons such as installation of an application program and system file upgrade. Detecting this change also backs up system information after each change (302). In this case, uninstall files are created when installing application programs.

After that, it examines the system resources, system files, registry, and various devices (HDD, Mouse, Audio, Video, Modem, etc.) that Windows has, and checks the background information of various application programs installed in Windows. Monitor (303).

At this time, if a problem occurs, the self-wizard changes the priority in the form of a top menu (TOP MOST Windows) and displays a message indicating that a problem has occurred to the user (305). Of course, if a problem does not occur, the system returns to the background job form and continues to monitor the system (303).

Next, the user is asked whether to return to the original state (306) if the user wants to use the system backup information that was saved at the same time as booting, or if there are multiple system file changes, one of the system file changes can be made. The system file can be restored using the system information backed up before the corresponding system file is changed, or in the case of a system failure caused by the installation of an application program, the application program can be deleted using the uninstall file created above. Restore the file (308). At this time, if the user does not want to remove only the message (307) and back to the background (Background Job) form to continue to monitor the system (303).

In this case, when recovering, the user is asked which level (Windows, Driver, Application) to restore and proceeds accordingly. Also, a Windows CAB file, a provided system utility CD, and a recovery CD may be used.

It is possible to configure a remote after-service system using the system file protection unit of the present invention as described above. In other words, the PC client performs diagnosis and monitoring of the system, and when a problem occurs, it recovers it with the current information, so it is possible to update newly changed device drivers or applications, or even to provide a new function provided by a remote server. And various upgrade information can be remotely connected to the server to perform a desired function.

In other words, when accessing a specific website that provides the installation service of the system file protector using the latest Internet technology, the system file protector is automatically installed after receiving the user's consent and the information is simultaneously stored on the local system and the web server. The program installed in the local area performs a backup and restore function, and automatically accesses the Internet web site for comparing the information, and compares the system file information to use for system recovery. In other words, by using the PUSH and PLUG-IN functions which are one of the Internet functions, the system analyzes the information of the corresponding system, receives the user's consent, analyzes the information of the system, and proceeds in the same way as above. .

The system file protection unit of the present invention is a utility for diagnosing and automatically recovering a problem when a software problem occurs in a user's PC, and is performed in the form of hidden / background job when executing Windows. The function of (Self-wizard) can be divided into the diagnosis function and the recovery function of the system.In the diagnosis function, it diagnoses the system resources of the OS and checks devices such as hard disk, memory, modem, audio, and video. It has a function to check and check the built-in application, and as a recovery function, this data can be used to restore the problem to the previous stage before the problem occurs. .

In addition, in the conventional after-sales service method, when a user has a problem, after-sales service personnel visit the user's home or office to solve the problem, and when the number of requests is large, the after-sales service could not be performed in a timely manner. In addition, the present invention enables to easily recover from the failure of the PC through the self-diagnostic and recovery function of the program, not only can reduce the number of service requests for personal users, but also can significantly reduce the cost of services. .
