Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a computer system comprising a plurality of processing units or a plurality of computers.
In particular, a record that records an event occurrence response device and an event occurrence response program of a computer system that detects various events such as failures that occur individually in each processing unit or each computer and performs a response process according to each event. Regarding the medium.

[0002]

2. Description of the Related Art In a computer system including a plurality of processing units or a plurality of computers, each application program stored in an auxiliary storage device such as an HDD or a main storage device such as a RAM incorporated in the computer system. Are executed independently.

[0003] Since each application program is independently executed, input data from the outside may be lost even when an abnormality such as a failure or power failure occurs in the process of executing each application, or even when the operation of the computer itself is normal. As in the case of being out of the allowable range, the case where the control target controlled by this computer system is abnormal, or the occurrence of input of normal information,
Programs for executing processes corresponding to various events occurring in the process of executing the relevant application programs are written in the respective application programs.

When the occurrence event indicates a specific failure, a failure occurrence message including a failure name named for the corresponding failure is displayed and output, and if necessary, an alarm is output with a buzzer sound. .

In some cases, a processing unit storing a program stores and holds the occurrence of the above-described event.
In particular, for an event relating to a failure, it is necessary to immediately investigate the cause of the failure and take countermeasures against the failure. Therefore, the event occurrence information is stored in the event occurrence history memory together with the occurrence time.

In the case where independent application programs are executed by each computer incorporated in a network such as a LAN, each computer executes the application program independently with respect to other computers. As with each processing unit in one computer, each computer is provided with a corresponding processing program and an event occurrence history memory corresponding to the occurrence of various events.

[0007]

However, each of the above-described computer systems has the following problems to be improved. In other words, there are many common parts in each processing executed by each processing unit in one computer and each computer incorporated in the network. There are also many common events. Further, the same failure may occur even with different processing contents. For the same failure, the same processing may be performed. For example, the warning message or warning sound of the same failure may be exactly the same.

However, in each of the computer systems described above, even if the processing contents are the same, each processing unit and each computer incorporated in the network independently holds a corresponding processing program.

As a result, there has been a problem that resources used by each application program (used size of memory and disk) are increased. Also, in the event occurrence history memory, the entire event occurrence information is recorded in the event occurrence history memory, so that the amount of data transferred for recording increases, and the data transfer traffic increases.
There is also a problem that the occupation time of the bus becomes long.

[0010] Further, from the viewpoint of maintenance management of the entire computer system, each processing unit and each computer incorporated in the network have fixed processing information corresponding to the above-described occurrence of an event therein. Therefore, when changing the registered contents of an event, etc., it is necessary to individually change the storage contents of all the processing units and computers in which the event is registered, and the time required for maintenance As the size increases, there is a concern that the probability of occurrence of a human error during the maintenance management operation increases.

Further, in the case of a form connected to a network, a failure related to the network is caused by a computer or the like that controls and manages the entire network and the network is configured with a simple network (SNMP).
rk Mamagement Protocol: Simple network management protocol). However, the SNMP cannot cope with a fault that occurs in each computer incorporated in the network.

For this reason, there is a possibility that the information recorded for each computer incorporated in the network may have a difference even in the information of the corresponding process for the same event, and the information of the corresponding process is centrally managed in the entire network. There was a problem that could not be done.

The present invention has been made in view of such circumstances, and provides an event database for centrally managing information on events occurring in each processing unit and each computer, thereby enabling each processing unit and each computer to execute the processing. It is possible to eliminate the processing for the occurrence of events to be stored and stored, to greatly reduce the information about the events to be stored and stored, to greatly reduce the resources such as the memory of the entire computer system, to reduce the manufacturing cost, and to reduce the entire computer system. An object of the present invention is to provide an event occurrence handling device and an event occurrence handling program of a computer system capable of simplifying maintenance and management.

[0014]

In order to solve the above-mentioned problems, an event occurrence correspondence apparatus of a computer system according to the first aspect of the present invention comprises:
In a computer system in which a software module is operated by a plurality of processing units, for each event that can occur in each processing unit, at least an index for specifying the corresponding event and an event database that records a corresponding process, An event occurrence detection unit that holds an index of an event related to the software module of

In the event occurrence handling apparatus of the computer system configured as described above, an index for identifying at least the corresponding event and a corresponding process are stored in the event database for each event that can occur in each processing unit.

The event occurrence detection unit provided in the processing unit that executes each software module does not store all the information of each event and the corresponding processing that needs to be executed when the event occurs. That is,
Only an index for specifying each event is stored in the event occurrence detection unit of the processing unit. When each event occurrence detecting unit detects an event occurrence, it transmits only the index of the event occurrence to the database server.

Therefore, the required storage capacity of the entire computer system can be reduced, and the processing load on each event occurrence detection unit can be reduced. According to a second aspect of the present invention, the database server in the event occurrence handling device of the computer system according to the above-mentioned invention has a database update notifying means for notifying each event occurrence detecting unit of an update notification when the storage content of the event database is updated. Each event occurrence detecting unit, when receiving the update notification from the database server, has index updating means for acquiring the updated storage content from the event database via the database server and updating the index held by itself. doing.

With this configuration, when the storage content of the event database is updated, the index held in each event occurrence detection unit is automatically updated. Claim 3

And a selection transmission unit for transmitting the event to the event occurrence detection unit of the processing unit.

With such a configuration, the database server keeps track of the processing units that use the event database. Therefore, when an event stored in the event database is updated, an update notification only needs to be sent to the registered processing unit, thereby simplifying the update process.

The event occurrence handling device of the computer system according to the present invention is applied to a computer system in which a plurality of computers are incorporated in a network. In this claim 4, for each event that can occur in each computer, an event database that records at least an index for specifying the corresponding event and a corresponding process is provided in each computer,
It holds the index of the event related to its own software module, and when the event occurrence is detected, the event occurrence detection unit that transmits the index of the event concerned, and receives the index transmitted from each event occurrence detection unit, and stores it in the event database. A database server computer for reading out the corresponding process corresponding to the event specified by the stored index and a corresponding process execution computer for executing the corresponding process read out by the database server computer.

Also in the event occurrence correspondence device of the computer system configured as described above, each computer corresponds to each processing unit in claim 1, and the database server computer corresponds to the database server in claim 1. Further, the corresponding processing execution computer corresponds to the corresponding processing executing unit of the first aspect.

Therefore, since the event occurrence detecting section of each computer only needs to store and hold the index of the event relating to its own work, the same operation and effect as in claim 1 can be expected.
According to a fifth aspect of the present invention, the database server computer in the event occurrence handling device of the computer system according to the fourth aspect is configured such that, when the database server computer itself is newly incorporated in the network, an address broadcast which outputs its own address to the network as broadcast communication. When receiving the broadcast, the event occurrence detecting unit provided in each computer includes an output unit, and updates the destination address of the index of the event by using the received broadcast address. Means.

In such a configuration, similarly to the second aspect, when the storage content of the event database is updated, the index held in the event occurrence detection unit provided in each computer is automatically updated. Is done.

According to a sixth aspect of the present invention, there is provided a computer system comprising: a plurality of processing units; and an event database for recording at least an index for specifying the corresponding event for each event which may occur in each processing unit and a corresponding process. This is a recording medium that stores a computer-readable event occurrence correspondence program for detecting occurrence and executing a response process for the corresponding event.

This event occurrence response program is
The computer holds, for each processing unit, an index of an event related to the job of the corresponding processing unit, outputs an index of the corresponding event when an event occurrence is detected, receives the output index, and stores the index in the event database. The corresponding process corresponding to the event designated by the corresponding index is read, and the read corresponding process is executed.

By using the recording medium on which the event occurrence response program configured as described above is recorded, the event occurrence response device of the conventional computer system which does not have the above-described functions can be easily described. The added function can be added.

According to the seventh aspect of the present invention, the event occurrence response program in the recording medium storing the event occurrence response program notifies each processing unit of an update notification when the storage content of the event database is updated. When the notification is received, the storage contents after the update are acquired from the event database, and the own index is updated. Therefore, similarly to the above-described claim 2, when the storage content of the event database is updated, the index held in each processing unit is automatically updated.

In each client 4, in addition to an application program execution unit (not shown) for executing a given application program, a notification unit 4 a for exchanging information with the database server 3, and an application program execution process. An event occurrence detection unit 4b for detecting an event that occurs and an index holding unit 4c are provided.

The index holding unit 4c stores and holds only an index of an event relating to its own business among the events stored in the event database 2. FIG. 4 is a flowchart showing a start-up process when the database server 3 and the client 4 are turned on and shift to a start-up state.

When the database server 3 is started, it reads all the data shown in FIG. 2 stored in the event database 2 and waits for communication of a data transmission request from each client 4. When each client 4 is activated, it communicates a data transmission request to the database server 3 via the notification unit 4a. The database server 3 transmits all the data in the event database 2 to the client 4 that has requested the data transmission, and registers a number (PID) specifying the client 4 that has communicated this time in the client database 3b.

The client 4 that has received all the data of the event database 2 from the database server 3 determines the event related to its own business among the events included in the received data, and uses only the index of the corresponding event as an index. Register in the holding unit 4c.

FIG. 5 is a flowchart showing the operation of each client 4 and the database server 3 during normal operation of the computer 1. When the event occurrence detection section 4b of each client 4 detects an event to be notified or recorded, , The index of the corresponding event held in the index holding unit 4c is read, and only this index is assigned the number (PID) of its own client 4 and the database server 3

The database server 3 has a client 4
When the index with the number of the client 4 is received from the event occurrence detecting unit 4b, the event database 2 is searched, the event name 2a and the corresponding process 2c corresponding to the index are read, and transmitted to the corresponding process executing unit 6. .

The response processing execution section 6 executes the response processing specified in the response processing 2c, and, if necessary, stores the number of the client 4 that occurred in the event file and the event name 2a or index 2b of the event in the event file. sign up.

FIG. 6 is a flowchart showing the operations of the database server 3 and each client 4 when the operator updates the event database 2 via the operation unit 5.

Reading / monitoring section 3a of database server 3
Is constantly monitoring the storage content of the event database 2,
When the storage content of the event database 2 is updated, the client 4 that has registered with the client database 3b and has communicated so far is read, and an update notification is transmitted to the client 4.

The client 4 that has received the update notification transmits a data transmission request to the database server 3 according to the procedure shown in FIG. 4, retrieves all the updated data from the database server 3, and retrieves this data. Index holding unit 4 stores only the indexes of the events necessary for itself
Register to c. That is, the storage content of its own index holding unit 4c is updated in accordance with the update of the storage content of the event database 2.

In the situation occurrence handling apparatus of the computer system according to the first embodiment configured as described above, the index 2b for specifying the corresponding event for each event that can occur in each client 4 in the event database 2 and the corresponding process 2c
Is stored. The event occurrence detection unit 4b provided in the client 4 that executes each application program stores and holds only the index of the event relating to the client 4 in the index holding unit 4c.

Therefore, the event database 2 only needs to store all the events that can occur in each client 4, and there is no need to store each event redundantly. Therefore, the required storage capacity of the entire computer system can be reduced as compared with the case where each client independently stores and retains each client including duplication with other clients as in the conventional apparatus.

When each event occurrence detecting section 4c detects an event occurrence to be notified or recorded, it only sends the index of the event to the database server 3 with a number specifying its own client 4. Therefore,
The processing load on each client 4 can be reduced, and the traffic volume of information on the bus can be reduced.

Further, the processing for responding to the event that has occurred in each client 4 is collectively executed by the response processing execution unit 6 based on the contents stored in the event database 2, and the event occurrence is centrally registered in a cumulative manner. Therefore, each event occurrence detection unit 4
Not only is it unnecessary to individually store and hold the occurrence of the event in b, but the maintenance management for the response process when the event occurs can be unified and facilitated.

Further, when the contents stored in the event database 2 are updated by the operator, the indexes stored in the index holding unit 4c of each client 4 are automatically updated. Therefore, when the detection event is changed, added, or deleted, the operator only needs to update the storage content of the event database 2 and does not need to perform the update operation on the storage content of each client 4. Maintenance work for the entire computer system is facilitated.
