Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fault monitoring method for an information processing network system including a plurality of information processing systems.

[Conventional technology]

In recent years, with the development of information processing technology centered on computers and high-speed digital communication technology using optical fiber cables, the use of large-scale network systems is progressing. In such a network system, an information processing system is established for each location, and these systems are connected using optical fiber cables or the like. Each information processing system uses each other's resources (for example, a host computer, data files) via optical fiber cables to effectively utilize scarce resources.

[Problem to be solved by the invention]

However, when such a network system becomes large-scale, the possibility of a failure occurring in the entire system inevitably increases, and its influence also spreads to the entire network. Therefore, in such a network system, it is necessary to reduce the occurrence of failure itself, and it is also necessary to provide appropriate display and recovery when a failure occurs.

However, conventionally, when a failure occurs, the person who discovers it first contacts the central system management department by telephone etc., and then the central management department contacts the management departments of each region. Notifications and confirmations will be made, and restoration work will be carried out by the person in charge. Similar work will be performed even after the failure is recovered.

Therefore, when a failure occurs that affects the entire system, a great deal of effort is required for the entire system.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fault monitoring system for an information processing network system that can appropriately deal with a fault when it occurs in the entire network or in each information processing system.

[Means to solve the problem]

A fault monitoring method for an information processing network system according to the present invention provides at least two information processing systems of a plurality of information processing systems connected to each other via a high-speed digital line, each having a role as a host for a different job, In a failure monitoring method for an information processing network system in which, when a terminal device in a predetermined information processing system executes a predetermined job, another information processing system is used as a resource as a host for the predetermined job, the information processing network When a network failure occurs that affects the entire system, the occurrence and recovery of the network failure is displayed on all information processing systems, and when a system failure occurs that involves a system that executes a specific job, the job is executed. The present invention is characterized in that the occurrence and recovery of the system failure are displayed in the information processing system, and when a network failure and a system failure occur in parallel, the occurrence and recovery of the network failure are displayed with priority.

[Effect]

According to the present invention, network failures and system failures are appropriately displayed at the corresponding bases, etc., and are displayed preferentially depending on the importance of the failure, so that various failures can be appropriately displayed. It becomes possible to respond.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 5 of the accompanying drawings. In addition, in the description of the drawings, the same elements are given the same reference numerals, and redundant description will be omitted.

FIG. 1 is a flowchart showing a fault monitoring method according to an embodiment of the present invention, and this method is applied in the systems of FIGS. 2 and 3. FIG. 2 is an overall configuration diagram of the information processing network system. As shown in the diagram, the head office information processing system la, which constitutes an information processing system,
The base information processing system 1b and the branch information processing system lc are connected by a high-speed digital line 2 made of an optical fiber cable or the like, and a failure line 3 is arranged in parallel to this high-speed digital line 2. Each information processing system 1 has a multiplexer 4a that connects the high-speed digital line 2 to its own system.

4b and 4c, and a failure switching unit 5a that connects the failure line 3 and its own system.

5t;, 5c. The head office information processing system 1a has a head office system 6a, the base information processing system 1b has a base system 6b, and the branch information processing system 1c has a branch system 6c.

FIG. 3 is a block diagram of the base information processing system 1b shown in FIG. 2. The multiplexing device 4b is dedicated to the high-speed digital line 2, and multiplexes various data from the base system 6b and sends it to the high-speed digital line 2, as well as multiplexed data sent via the high-speed digital line 2. It functions to convert the data into individual data and pass it to the base system 6b. The failure switching unit 5b switches the data transmission line from the high-speed digital line 2 to the failure line 3 when a network failure, which will be described later, occurs. The communication control unit 7b controls data communication, and includes a host computer 8b that can execute predetermined jobs.
or connected.

The gateway processor 9b is a computer that implements protocol conversion, iMm for facsimile communication (FAX mail) with other information processing systems, media conversion, and additional functions for network management. A readable and writable memory 10b is attached. This memory 10b is used to temporarily store transmission data, etc., and the gateway processor 9b
By working together with the Internet, it is possible to make effective use of the high-speed digital line 2.

The voice recognition response unit i1b converts voice data to EDP data and EDP data to voice data, thereby making it possible to notify failure information by voice and to transmit EDP data by telephone. The facsimile control section 12b controls a facsimile connected to its own information processing system 1b and performs code image conversion, and the data module 13b performs data communication between the gateway processor 9b and the private branch exchange 15b. The private branch exchange 15b is a large capacity digital electronic exchange, which includes a personal computer 16.
b: A large number of facsimiles 17b and telephones 18b are connected.

The head office information processing system 1a and the branch information processing system IC are also configured in substantially the same manner as the base information processing system 1b shown in FIG. However, the head office information processing system 1
As for a, a computer (not shown) may be provided to comprehensively monitor the entire information processing network system, and a data communication control device (not shown) may be provided to perform comprehensive communication control. Further, for the branch information processing system IC, the host computer that performs a predetermined job may be omitted.

Next, the operation of the above system will be explained with reference to FIG.

According to this system, it becomes possible to effectively utilize all the resources of the information processing network system. First, the head office information processing system 1a has a host computer 8a with a sales management system and personal computers 16a1 and 16a2 that can be used for multiple purposes.
b has a host computer 8b with a development support system and personal computers 16b and 16b2 that can be used for multiple purposes, and ■ branch information processing system IC has a host computer 8c that has an inventory management system and personal computers 16c and 16c2 that can be used for multiple purposes. And so.

Then, employees at the base office use the base information processing system lb.
The host computer 8c in the branch information processing system lc can be operated using the personal computer 16b in the branch office, and the inventory management system can be executed. In addition, employees at the head office can operate the base information processing unit 8b using the personal computer 16a in the head office information processing system la, and can proceed with product development using the development support system. Furthermore, branch employees can use the personal computer 16c in the branch information processing system lc to operate the host computer 8a in the head office information processing system la, and use the sales management system to compare the sales status of their own branch with that of other branches. You can do it.

Note that such effective use of resources is possible not only between a personal computer and a host computer, but also between post computers. Data communication at this time is performed via the high-speed digital line 2, but when the high-speed digital line 2 is busy, the data may be temporarily stored in the memory 0b within the own information processing system. Note that this data is stored in the gateway processor 9a.

This is done under the control of 9b and 9c.

When a failure occurs in a system such as the one described above, the effects are far-reaching.

The failure that has the greatest impact is what is called a network failure. This occurs, for example, when the central communication control device (not shown) in the information processing system at the head office goes down, or when the high-speed digital line 2 becomes unable to communicate nationwide, and the entire information processing network system system becomes unusable. The next most influential failure is what is called a system failure. This occurs, for example, when the host computer 8b in the base information processing system fails, and if this occurs, for example, in the example of FIG. 4, the development support system becomes unusable for all information processing network systems. In addition, there are failures within each information processing system, and these cases rarely affect the entire information processing network system.

22, high-speed digital line 2 and multiplexing equipment 4a, 4b
, 4c, the fault switching section 5a of the faulty information processing system.

5b and 5c are activated, and communication is performed via the failure line 3. Therefore, normal system services will not be possible, but important services and monitoring will be performed normally in all systems.

Next, processing when a failure occurs will be explained with reference to FIG.

First, whether or not a failure has occurred is constantly monitored (step 101), and if there is no failure, the system operates normally (step 1o2). Here, if the occurrence of a network failure is detected in step 101, step 103
A network failure is displayed. Under this failure, the entire system shown in FIG. 4 becomes unusable. Therefore, this display information is sent via the failure line 3 and displayed to all the information processing network systems, and for example, a display as shown in FIG. 5(a) is broadcast all at once.

Specifically, this information is displayed on the display of the personal computer of each information processing system, and is also displayed audibly via a telephone or the like. As a result, all information processing network systems will be notified of the fact that a failure has occurred and the degree of impact.

Next, the cause of the failure is investigated by the function of the gateway processor 9, and a corresponding failure recovery method (previously stored in memory) is instructed on a monitoring display (not shown) (step 104). This allows the staff to know where the failure has occurred, its cause, and the method for recovery, so that they can immediately begin work on recovery from the failure. Note that this state continues until the network failure is recovered in step 105.

When the network failure is recovered, this is automatically detected by the gateway processor 9 etc., and step 10
A fault recovery display as shown in FIG. 5(b) is displayed for all the terminal devices (for example, personal computers, facsimile machines) that displayed the occurrence of a fault in step 3 (Stellar Abu 106). and,
The system will resume normal operation. After recovery, all systems can resume using resources without having to wait for a call from a staff member.

When the fault detected in step 101 is a system fault, the fault display in step 103 is, for example, the fifth
The result will be as shown in Figure (C). That is, for example, when the host computer 8b goes down in the system shown in FIG. 4, the development support system becomes unusable in all information processing network systems, and a message to that effect is displayed. After the failure is recovered, the display shown in FIG. 5(d), for example, is displayed in step 106. At this time, other systems (systems in which no failure has occurred) continue to operate normally.

The system of the present invention not only notifies (displays) the occurrence and recovery of a failure in a personal computer or the like using the above-described procedure, but also notifies the user of a failure by using facsimile (FAX mail) or telephone.

First, regarding notifications by FAX and email, see Figure 5 (a).
) to (d) are transmitted via the high-speed digital line 2 or failure line 3 shown in FIG. 2, and are stored in the memory 10a shown in FIG. 3.

10b and 10c. Then, the gateway processors 9a, 9b, 9c read this and send it to the facsimile 17a, 17b under the control of the facsimile control units 12a, 12b, 12c.

17c is output as is. Therefore, the personal computer 16a
, 16b, 16c are not turned on (at night), the fact of failure occurrence and recovery will be appropriately notified in paper form.

Furthermore, simultaneous broadcasting is also carried out using the telephones 18a, 18b, and 18c. That is, the gateway processors 9a, 9
b, 9c are memories 10a, 10b.

The information regarding the occurrence and recovery of a failure stored in the voice recognition response unit 11a is read out.

11b, llc. Then, the voice recognition response unit 11
a, llb, and llc convert this into voice information and send it to telephone 1.
Call the staff at 8a, 18b, and 18c.

Here, there are important and unimportant information regarding failures, and there is also information that does not need to be announced on holidays or at night. Therefore, schedule management is performed for announcements. At the same time, when multiple failures occur, notifications are made according to priority. That is, the first priority regarding the failure and operation information shown in FIG. 5...the second priority for network failure occurrence information as shown in FIG. 5(a)...the network failure as shown in FIG. 5(b) Third priority for recovery information: system failure occurrence information as shown in FIG. 5(C); fourth priority for system failure recovery information as shown in FIG. 5(d).

In this way, there will be no confusion due to dissemination of various types of information. Note that it is not efficient to make multiple calls when there is no response by telephone (for example, when the staff is absent, the telephone is in use, or the password is not returned correctly), so the number of calls is limited to three times, for example.

〔Effect of the invention〕

As explained above in detail, according to the fault monitoring method of the information processing network system according to the present invention, network faults and system faults are appropriately displayed at the corresponding bases, etc., and are prioritized according to the importance of the fault. Since the information will be displayed in a realistic manner, it will be possible to respond appropriately to various obstacles.
