In addition, the learning distributed environment management server may be configured to enable the system construction and operation of each distributed server by installing a solution.

Therefore, the learning distributed environment management server can realize the sharing of learning resources and management of the distributed server only by installing a simple solution (predetermined management program) on the distributed server. For example, the learning distributed environment management server may install a solution in a distributed server in a short time (for example, 3 to 4 hours) and enable e-learning services in the distributed server. In addition, the learning distributed environment management server may check (check), diagnose, and recover in the event of an error in real time.

It may be a learner's terminal. The terminal will be described in detail later.

On the other hand, shared learning resources are learning resources registered to be shared with other distributed servers by the administrator of the distributed server. The shared learning resources may be all or part of the learning resources stored in the storage area of the distributed server.

The learning distributed environment management server 110 manages shared learning resources. In detail, the learning distributed environment management server 110 receives identification information for distinguishing learning resources from the connected distributed server. In addition, the learning distributed environment management server 110 registers learning resources distinguished by identification information as shared learning resources. Here, the identification information may include a content ID, address information regarding a location where the corresponding learning resource is stored, and information representing the content of the learning resource, that is, information summarizing the content of the learning resource.

In addition, the identification information may be implemented in the metadata format of the learning resource. Here, it will be apparent to those skilled in the art that the metadata may be implemented in various forms including information that can distinguish the contents such as index information of the contents. Therefore, the learning distributed environment management server 110 may receive metadata of the content as identification information from the distributed server.

Thereafter, the learning distributed environment management server 110 may generate list information of registered shared learning resources. In addition, the learning distributed environment management server 110 may provide list information to a distributed server requesting a shared learning resource search.

In addition, the learning distributed environment management server 110 may receive information (hereinafter, referred to as state information) about a driving state of a management program installed in the distributed server. Here, the management program is a program implemented so that the distributed server can perform all types of operations for managing learning resources. For example, the management program may perform operations such as setting of shared content, content creation, and providing a template for content production.

The learning distributed environment management server 110 may check the occurrence of an error of the corresponding distributed server by using the information about the driving state of the received management program. Thereafter, the learning distributed environment management server 110 may display a warning message to an administrator terminal connected to the learning distributed environment management server 110 when an error occurs. In addition, the learning distributed environment management server 110 may solve the identified error. This will be described in detail with reference to FIG. 2.

In addition, the learning distributed environment management server 110 may generate statistical information using the received state information. Here, the statistical information may include information about the network 120 interruption rate, the processing rate for the error, and the server operation status.

The network 120 includes a wired and wireless communication network such as a mobile communication network and an internet network. Herein, the mobile communication network includes all wired and wireless communication networks capable of providing learning resources such as telephone connection and contents as well as WCDMA. Hereinafter, the Internet network will be described as an example.

The Internet network is a computer network 120, which is a local area network (LAN) connected by coaxial cable, fiber optics or wireless, or a long-distance such as a packet switched network (PSTN), integrated services digital network (ISDN), or broadband integrated information network (B-ISDN). It may be a communication network (WAN), and may include a cable TV network, a satellite network that enables internet connection, a wireless internet network, and an internet network of a mobile communication company. Since the Internet network is a known technology, detailed descriptions thereof will be omitted to clarify the gist of the present invention.

Hereinafter, the distributed servers connected to the learning distributed environment management server 110 and the terminals connected to each distributed server will be described in detail.

The distributed servers 130 and 140 are connected to the learning distributed environment management server 110 described above. In the present invention, there may be a plurality of distributed servers 130 and 140. Hereinafter, for convenience of understanding and explanation of the present invention, the first distributed server 130 is a server providing a shared learning resource, and the second distributed server 140 requests the shared learning resource to the first distributed server 130. The description will be divided into servers. However, the present invention is not limited thereto and includes all embodiments of registering and providing shared learning resources in one or more distributed servers 130 and 140.

In addition, the terminal is a terminal connected to the server. Hereinafter, for convenience of understanding and explanation of the present invention, a terminal (for example, the learner terminal 131 or the instructor terminal 132) connected to the first distributed server 130 is collectively referred to as a first terminal. 2 The terminal (for example, the learner terminal 141 or the instructor terminal 142) connected to the distributed server 140 will be collectively referred to as a second terminal.

The first distributed server 130 selects all or part of the stored learning resources as shared learning resources. The first distributed server 130 may transmit identification information of the selected shared learning resource to the learning distributed environment management server 110. Here, the identification information may include content ID, address information of the distributed server storing the corresponding learning resource, and information representing the content of the corresponding learning resource, that is, information summarizing the contents of the learning resource.

Thereafter, when the first distributed server 130 receives the shared learning resource request from the second distributed server 140, the first distributed server 130 may transmit the shared learning resource to the second terminal. In detail, the first distributed server 130 may execute the shared learning resource, and the shared learning resource executed in the first distributed server 130 is displayed at the second terminal connected to the second distributed server 140. This will be described in detail with reference to FIG. 3.

The second distributed server 140 may receive a shared learning resource search request from the connected second terminal. Accordingly, the second distributed server 140 may transmit a shared learning resource search request to the learning distributed environment management server 110, and receive list information on the shared learning resources from the learning distributed environment management server 110. .

The second distributed server 140 may provide the received list information to the connected second terminal. In addition, when receiving selection information of a specific shared learning resource from the connected personal terminal, the first distributed server 130 may request execution of the shared learning resource corresponding to the received selection information.

As described above, the first distributed server 130 and the second distributed server 140 may share learning resources set to be shared with each other. As shown in FIG. 1, sharing of learning resources is not performed through a central server (shared learning resource sharing server of the present invention), that is, a web between the first distributed server 130 and the second distributed server 140. It is a form of resource sharing using services.

In the present specification, the terminal is a personal computer (PC), a hand-held PC, and a notebook PC (notebook PC), which communicate with a wired or wireless Internet network, as well as a personal digital assistant (PDA), a cellular phone, and a PCS (Personal). The terminal may include a terminal for communicating with a mobile communication network, such as a communication service (WCDMA) phone, a WCDMA phone, a CDMA-2000 phone, a mobile broadband and system (MBS) phone, and the like.

Hereinafter, a description will be given on the assumption that each terminal is a terminal such as a PC implemented to use a communication service of the Internet network, but it is apparent to those skilled in the art that the terminal is not limited to the terminal type.

The first terminal is a terminal connecting to the first distributed server 130. The first terminal may be an administrator terminal of the first distributed server 130. The first terminal may set a specific learning resource stored in the first distributed server 130 as a shared learning resource according to a selection input of a terminal user (for example, a server administrator). The first distributed server 130 transmits the identification information of the learning resource set as the shared learning resource to the learning distributed environment management server 110 as described above.

The second terminal is a terminal connected to the second distributed server 140. The second terminal may be a customer terminal using a service of the second distributed server 140. The second terminal can request the search for the shared learning resource. In addition, when receiving list information on the shared learning resource from the second distributed server 140, the execution of a specific shared learning resource may be requested.

In this case, the selected specific shared learning resource is executed in the first distributed server 130 and displayed on the second terminal as described above.

The first terminal has been described as an administrator terminal and the second terminal as a customer terminal. However, it will be apparent to those skilled in the art that the first terminal and the second terminal are not limited thereto, and the first terminal and the second terminal may be all terminals connected to each of the first distributed server 130 and the second distributed server 140.

So far, a learning distributed environment management system according to an embodiment of the present invention has been described with reference to FIG. 1. Hereinafter, the learning distributed environment management server 110 will be described in detail with reference to FIG. 2.

2 is a block diagram for explaining the configuration of the learning distributed environment management server 110 according to an embodiment of the present invention.

The learning distributed environment management server 110 manages learning resources shared among a plurality of distributed servers. A user of the first terminal, that is, a learner, accesses the second distributed server 140 to use the learning resources stored in the first distributed server 130 (of course, shared learning resources set to be shared with the second distributed server 140). Can be.

Suppose, as in the example above, that A and B decide to share learning resources (such as lecture videos). In this case, the learner (university B student) connects to the web server of the university B (second distributed server 140), and the shared learning resource stored in the web server of the university A (the first distributed server 130), for example. Video lessons are available. At this time, according to the exchange agreement between the two universities, the learner can be credited to college B.

Therefore, in addition to sharing learning resources between A and B universities, it is necessary to share historical information on the execution of learning resources. In other words, even if a learner (university B university student) completes the lecture of university A, it is necessary to receive credits from university B.

Therefore, the university A's web server needs to store the execution history information of the shared learning resource executed by the learner and provide the university's web server.

The present invention enables a learner connected to the second distributed server 140 to execute a shared learning resource through the first distributed server 130, and may provide history information on the execution of the shared learning resource.

Referring to the above-described example, the learner may access the university B web server, execute the shared learning resource stored in the university A server, and receive the history information accordingly.

Hereinafter, the learning distributed environment management server 110 for managing shared learning resources will be described in more detail by dividing into functional configurations.

Referring to FIG. 2, the learning distributed environment management server 110 may include a communication unit 210, a learning resource management unit 220, a state management unit 230, and a storage unit 240.

The communication unit 210 receives identification information for distinguishing learning resources from the first distributed server 130. In addition, the communication unit 210 may transmit and receive data and signals including the learning resource request, the list information request for the shared learning resource, the requested list information, and the like with the second distributed server 140. In addition, the communication unit 210 may transmit and receive data and signals with all devices other than the distributed server through the network 120.

The learning resource manager 220 registers the shared learning resource using the identification information received by the communication unit 210. In detail, the learning resource manager 220 registers the learning resource identified by the identification information received from the first distributed server 130 as the shared learning resource. For example, suppose the first distributed server 130 sets a lecture learning resource called "first lecture of a civil law lecture" as a shared learning resource. The first distributed server 130 transmits identification information of the corresponding learning resource to the learning distributed environment management server 110. The learning resource manager 220 may register the lecture learning resource as the shared learning resource according to the received identification information.

In addition, the learning resource manager 220 may generate list information on the shared learning resource. That is, the learning resource manager 220 may generate a list of learning resources to be shared which are received from the first distributed server 130 (including other connected distributed servers). The generated list information may be provided to a distributed server requesting a search for shared learning resources.

In addition, the learning resource management unit 220, through the above-described management program, to each distributed server, a content management tool (Contents Management System (CMS)), a content authoring tool (Authoring Management System (AMS)) and a content development management tool (Contents Development). Management System (DMS) can be provided.

Here, the content management tool is a tool for managing the execution of the learning content and the history information, and can be driven according to the SCORM protocol. In detail, the content management tool is provided to a distributed server. The distributed server can minimize the time required for content management using the content management tool, reduce the development cost of the learning process, and provide customized learning content considering the characteristics of the learners. For example, suppose that new content is stored in the first distributed server 130. The first distributed server 130 has to perform a separate coding operation in order for the administrator to arrange newly stored content in the first distributed server 130. The content management application may automatically perform coding operations that were manually performed, store new content in the first distributed server 130, and perform distribution (including distribution for registration as shared content).

In addition, the content authoring tool supports the creation of content through collaboration between professors and authors, based on templates based on learning models, and provides templates for producing learning content. Content authoring tools (collaboration support) enable rapid content development. For example, the content authoring tool may provide a function of directly mounting and managing html written on the first distributed server 130 including the html authoring tool. Accordingly, a user of the first terminal may access the first distributed server 130 and may easily create a video lecture content using a content authoring tool.

In addition, the content development management tool manages the entire process of content development (planning, analysis, production, inspection, etc.), thereby improving content development productivity and development progress efficiency. In addition, through the content development management tool, communication between instructors, developers, designers, multimedia managers and operators can be facilitated, data exchange and efficient operation can be implemented.

The state manager 230 may provide information about a driving state of a management program installed in each server from a distributed server (the first distributed server 130 or the second distributed server 140) connected to the learning distributed environment management server 110 ( Hereinafter referred to as status information).

Here, the status information may include connection status information, server status information, and error information. In this case, the connection state information is information on the connection state of the network 120 between the first distributed server 130 and the learning distributed environment management server 110, and the server state information is about the operation state of the first distributed server 130. Information. In addition, the error information is information on an error generated in the first distributed server 130. In particular, the error information may be information about an error of a program installed in the first distributed server 130 to provide shared content.

Meanwhile, the state manager 230 may receive state information from the first distributed server 130 using SNMP (simple network protocol management). Here, SNMP is an application layer protocol defined on TCP / IP for the purpose of monitoring the network 120 equipment. In the present invention, SNMP is used as a protocol for monitoring the first distributed server 130. That is, the state manager 230 manages the network 120 connection state, the state (performance, etc.) of the first distributed server 130 by using SNMP, and is generated by a management program installed in the first distributed server 130. Error can be detected.

In addition, when an error is detected, the state manager 230 may generate a warning message, and provide the generated warning message to an administrator terminal connected to the learning distributed environment management server 110. Here, the provided warning message is displayed on the administrator terminal, so that the administrator can check the error occurring in the first distributed server 130.

In addition, the state manager 230 may solve the detected error. In detail, the state manager 230 determines whether an error that occurs is an individual problem of the first distributed server 130 or a common problem that may occur in another distributed server (eg, the second distributed server 140). can do. For example, the state manager 230 may determine whether the error is due to a management problem of the first distributed server 130 alone or a lack of a version upgrade of the management program installed in the first distributed server 130. have.

When it is determined that the generated error is an individual problem, the state manager 230 may individually process the error, such as modifying only the management program installed in the first distributed server 130. Alternatively, when it is determined that the generated error is a common problem (for example, an error generated due to a low version), the state manager 230 collectively manages the same version of the management program as the program installed in the first distributed server 130. By upgrading, you can solve the error. In this case, the learning distributed environment management server 110 may detect one occurrence of an error and may prevent the occurrence of an error in all distributed servers that may potentially generate an error.

In addition, the state manager 230 may generate statistical information using the received state information. Here, the statistical information may include information about the network 120 interruption rate, the throughput rate for the error, and the server uptime rate. That is, the state manager 230 may perform statistical processing of the state information on the basis of the first distributed server 130 or the time on the interruption, error processing, and server operation status of the network 120.

The generated statistical information may be displayed by providing a terminal of an administrator connected to the learning distributed environment management server 110.

The storage unit 240 may store identification information, list information on shared content, and the like. In addition, the storage unit 240 may store a predetermined program for controlling the overall operation of the shared content providing server, data input / output, and various data processed.

In the present specification, the communication unit 210, the learning resource management unit 220, the state management unit 230, and the storage unit 240 (in particular, the learning resource management unit 220 and the state management unit 230) are functionally expressed. That is, although each functional unit is expressed separately, this is for convenience of description and may be implemented in one circuit (micro circuit as one logic unit).

So far, the learning distributed environment management server 110 has been described with reference to FIG. 2. Hereinafter, a process of providing a shared learning resource will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating a process of providing a shared learning resource according to an embodiment of the present invention.

In the present invention, the first distributed server 130 and the second distributed server 140 may be installed a program (hereinafter referred to as a management program) that can perform a specific task. Herein, the management program may set sharing of learning resources, execute sharing learning resources, and request execution of sharing learning resources. In addition, the management program may implement all operations for managing learning resources, as described above.

The management program may be transmitted from the learning distributed environment management server 110. In this case, the management program may be installed in the distributed server.

Subsequently, all the processes of the present invention can be implemented through the above-described management program. Hereinafter, although the management program may not be specified as the subject of the operation, it is obvious that the present invention may be implemented through a program installed in the server.

In addition, the management program may be installed offline (stored in a recording medium such as a CD) in the distributed server, or transmitted online from the learning distributed environment management server 110 to the distributed server online (for example, through an Internet network). May be installed.

The learning distributed environment management server 110 may automatically install a management program on a distributed server through the network 120. The learning distributed environment management server 110 may provide the above-described content management tool, content authoring tool, and content development management tool through the installed management program. In addition, the learning distributed environment management server 110 may receive related information (for example, the number of execution of the shared learning resource, etc.) for sharing the learning resource through the management program.

In addition, the learning distributed environment management server 110 may receive state information, diagnose a state of the distributed server, and automatically recover the state through a management program, which will be described in detail with reference to FIG. 4.

Hereinafter, referring to FIG. 3, examples of shared contents such as lecture videos or MP3 lecture materials, among shared learning resources, include a process of providing shared content and a process of providing history information according to execution of the provided shared content. Let's take a closer look.

In step S301, the first distributed server 130 sets up shared content. In detail, the first distributed server 130 sets contents to be shared among them. In this case, the first injection server may set content to be shared and set according to the setting information input from the connected manager terminal (first terminal).

Subsequently, in step S302, the first distributed server 130 generates identification information of content to be shared and transmits it to the learning distributed environment management server 110. Here, the identification information may be metadata of the corresponding content. Meta data is machine language, the part of code that can identify content on a server. For example, the content may include the type, title, format, storage location, creator, year of production, and the like.

Then, in step S303, the learning distributed environment management server 110 registers the content corresponding to the identification information received in step S302 as the shared content. In more detail, the learning distributed environment management server 110 may register content corresponding to identification information, that is, content that the first distributed server 130 intends to share as shared content.

For example, the learning distributed environment management server 110 may read only the content title and the storage location from the identification information. The learning distributed environment management server 110 may set the read content title and the storage location as the shared content item. Thereafter, the learning distributed environment management server 110 may provide the corresponding content as the shared content when the shared content is required by the administrator or the distributed server.

Subsequently, in step S304, the learning distributed environment management server 110 may generate list information about registered shared content. The learning distributed environment management server 110 may generate list information by selecting and identifying identification information of registered shared content. For example, the learning distributed environment management server 110 may generate list information by collecting titles and storage locations of registered shared content.

On the other hand, in steps S305 and S306, the second terminal (collectively, the terminal connecting to the second distributed server 140, as described above) requests the second distributed server 140 to search for shared content ( S305). Accordingly, the second distributed server 140 may request a shared content search from the learning distributed environment management server 110 (S306). This is the case where the user of the second terminal wants to use the shared content.

For example, assume that the first distributed server 130 is a Seoul National University web server, and the second distributed server 140 is a Korea University web server. Korea University students can access Korea University web server using their ID and password. At this time, if a Korea University student wants to use lecture content stored in a web server of Seoul National University linked to Korea University, the student may request to search for lecture content shared with a web server of Korea University. Korea University web server may request a shared lecture content search to the learning distributed environment management server (110).

Subsequently, in steps S307 and S308, the learning distributed environment management server 110 provides list information about the shared content to the second distributed server 140 (S307). In this case, the second distribution server 140 receiving the list information may transmit the received list information to the second terminal.

In this case, the shared content providing server may provide a search tool to the second terminal. In this case, the user of the second terminal may search list information of the learning distributed environment management server 110 using a search tool. The search tool may be implemented in various ways, such as title search and storage location search (eg, searching for shared content stored in the Seoul National University web server).

Subsequently, in steps S309 and S310, the second terminal may select shared content (S309). In operation S310, the second terminal may transmit information on selecting the shared content (hereinafter, referred to as selection information) to the second distribution server 140. In detail, the second terminal may select the shared content that the user wants to execute through the user's input, and the selection information may be transmitted to the second distributed server 140.

In FIG. 3, the selection information is transmitted to the second distributed server 140, but the selection information may be directly transmitted to the first distributed server 130 (that is, the distributed server storing the shared content). In this case, the request step (step S311) of the selected shared content to be described later can be omitted.

Subsequently, in step S311, the second distributed server 140 may request shared content from the first distributed server 130 according to the selection information received from the second terminal in step S310. Here, the first distributed server 130 is a server in which the selected shared content is stored.

Subsequently, in step S312, the first distributed server 130 directly transmits the corresponding shared content to the second terminal according to the request received in step S311. That is, the first distributed server 130 executes the corresponding shared content according to the received request. In this case, the executed shared content is displayed on the second terminal.

In detail, when executing the selected shared content, the first distributed server 130 causes the execution window of the shared content to be displayed on the display area of the second terminal. In this case, the user of the second terminal may control the shared content running in the first distributed server 130 through an input to the second terminal.

For example, suppose the shared content is video lecture content. The user of the second terminal may start the corresponding video lecture content by inputting a "start" button. In addition, the user of the second terminal may control a corresponding video lecture content by performing a button input such as “pause” or “stop”.

Subsequently, in step S313, when execution of the shared content ends, the first distributed server 130 may store history information on which the shared content is executed in the storage area.

The history information is information on an execution history of shared content, and may include, for example, a title of executed content, user information requesting execution of shared content, and identification information of a distributed server that requested shared content.

Thereafter, in steps S314 and S315, the second terminal may request history information from the second distribution server 140 (S314). In addition, the second distributed server 140 may request the requested history information from the first distributed server 130 (S315).

In FIG. 3, the second terminal requests history information to the first distribution server 130 through the second distribution server 140, but the second terminal requests the history information directly to the first distribution server 130. May

Subsequently, in steps S316 and S317, the first distribution server 130 may transmit the history information requested in step S315 to the second distribution server 140 (S316). In addition, the second distributed server 140 receiving the history information may provide the history information received to the second terminal (S317).

In FIG. 3, the first distributed server 130 provides the history information to the second terminal through the second distributed server 140, but the history information is immediately transmitted to the second distributed server 140. It may be stored in a storage area of the second distributed server 140. In this case, the second terminal may request history information from the second distribution server 140, and the second distribution server 140 may provide the requested history information to the second terminal.

In addition, in FIG. 3, the shared content has been described as a representative example, but the present invention may be applied to all shared learning resources (including content, templates for content creation, and workflow for content production management). Is apparent to those skilled in the art.

So far, the process of providing the shared content according to an embodiment of the present invention has been described with reference to FIG. 3. Hereinafter, a process of managing the state of the first distributed server 130 will be described in detail with reference to FIG. 4.

4 is a flowchart illustrating a process of managing the state of the first distributed server 130 according to an embodiment of the present invention.

According to an embodiment of the present invention, the learning distributed environment management server 110 installs a management program collectively or selectively on each distributed server. Accordingly, an administrator of the learning distributed environment management server 110 may remotely manage a distributed server in which the corresponding management program is installed.

That is, the learning distributed environment management server 110 may query the failure of the distributed server, the connection state, and the server state. The learning distributed environment management server 110 may solve an error generated when an error occurs as a result of the inquiry.

In addition, the learning distributed environment management server 110 may calculate statistics of a network network driving state (or a distributed server driving state) such as a network interruption rate and a failure processing situation. The calculated statistics can be provided to the manager.

That is, according to the embodiment of the present invention, the learning distributed environment management server 110 may manage integrated distributed servers. It may be possible to collectively manage through the above-described management program. In addition, according to an embodiment of the present invention, the learning distributed environment management server 110 may not only manage the integrated distributed server, but also upgrade the management program remotely.

Hereinafter, referring to FIG. 4, when the learning distributed environment management server 110 encounters an error in the distributed server, the process of resolving this is taken as an example. This will be described in detail.

In operation S410, the learning distributed environment management server 110 receives state information. Here, as described above, the state information may include connection state information, server state information, and error information.

In addition, the learning distributed environment management server 110 may receive status information from the first distributed server 130 using SNMP (simple network protocol management). Here, SNMP is an application layer protocol defined on TCP / IP for the purpose of monitoring the network 120 equipment, and is used as a protocol for monitoring the first distributed server 130.

That is, the learning distributed environment management server 110 may receive status information including connection status information, server status information, and error information by using SNMP.

Subsequently, in step S420, the learning distributed environment management server 110 may detect whether an error occurs in the first distributed server 130 using error information among the state information received in step S410.

The learning distributed environment management server 110 may generate statistical information when an error occurrence is not detected, that is, when the first distributed server 130 is normally driven (S470).

Subsequently, in step S430, when an error occurrence is detected in step S420, the learning distributed environment management server 110 outputs a warning message to the connected manager terminal. In detail, the learning distributed environment management server 110 may generate a warning message informing of an error generated in the first distributed server 130. The generated warning message may include information on the type of the corresponding error or the server where the error occurred. The learning distributed environment management server 110 may transmit the generated warning message to the manager terminal connected to the learning distributed environment management server 110 to be displayed on the display area of the manager terminal.

Subsequently, in step S440, the learning distributed environment management server 110 determines whether the detected error is an error that can be solved through an upgrade of the management program installed in the first distributed server 130. For example, the learning distributed environment management server 110 determines whether the error occurred due to a lower version of the management program installed in the first distributed server 130.

In detail, the learning distributed environment management server 110 determines whether the detected error is an individual problem of the first distributed server 130 or a version problem of the management program installed in the first distributed server 130.

In this case, in step S450, when it is determined that the learning distributed environment management server 110 is an individual problem of the first distributed server 130 in step S440, the learning distributed environment management server 110 may solve the detected error.

On the other hand, in step S460, the learning distributed environment management server 110, if the error detected in step S440 is an error that can be solved through the upgrade of the management program installed in the first distributed server 130, the first distributed server 130 It is possible to collectively upgrade the management programs installed on distributed servers with the same management management program installed in the management management program installed in the server.

For example, assume that an error occurred in the first distributed server 130 is an error caused by the installation of a low management program. The learning distributed environment management server 110 determines that the error is caused by the low version of the management program. In addition, the learning distributed environment management server 110 may select an upgrade of an installed management program as a solution to an error. In this case, a lower version of the management program may be installed in other distributed servers. Accordingly, the learning distributed environment management server 110 may upgrade the installed management program for all distributed servers in which the management program of the same version as the management program in which the error occurs is installed. Through this, the learning distributed environment management server 110 may prevent an error occurring in another distributed server in advance.

Thereafter, in step S470, the learning distributed environment management server 110 generates statistical information. In detail, the learning distributed environment management server 110 generates statistical information based on the state information generated in step S410. As described above, the statistical information may include information regarding the network 120 interruption rate, the throughput rate for the error, and the server operation rate.

Although not shown in the drawing, the generated statistical information may be transmitted to the manager terminal connected to the learning distributed environment management server 110 and displayed on the display area of the manager terminal.

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

For example, the computer-readable recording medium may include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.

It may also include the implementation in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium can also be distributed over computer systems connected via a network 120 so that the computer readable code is stored and executed in a distributed fashion.

And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
