Abstract

PURPOSE:To dispense with an. operator and to attain the reduction of personnel expenses and the improvement of reliability by providing with a request command generating means and a response command generating means, and monitoring the state of an opposite program at every constant time mutually with each other. CONSTITUTION:Prescribed lapse of constant time is detected by a time detecting means 3, and the request command generating means 4 receives the trigger of detection, and generates the normal operation confirmation request command of the opposite program. The command is transmitted to an opponent via a communication interface 9. A request command analyzing means 6 on the opposite side analyzes the content of a received request command, and checks the state of its own program. The response command generating means 7 generates a response command according to the result of check. The response command is returned to a request side. A response command analyzing means 5 on the request side analyzes the content of the response command from the opposite side, and judges whether or not the opposite program is operated normally.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program status mutual monitoring system, and in particular, in a client / server model in which a plurality of programs communicate with each other using a communication line, for confirming the normality of the operation of a communication partner program. Program status mutual monitoring system.

[0002]

2. Description of the Related Art In recent years, due to advances in computer technology, the performance of workstations has been remarkably improved.
There is a movement to distribute the functions that have been concentrated in the host until now to the workstations. One example of this movement is the client / server model. In these systems, a plurality of programs cooperate with each other to communicate with each other via a line and perform processing. Therefore, it is necessary for each individual program to operate normally.

In the conventional program state mutual monitoring system, an operator causes each program to process evaluation data, confirms the processing result, and notifies each other.

[0004]

In the conventional program status mutual monitoring system described above, the operator periodically causes the system to process data for system evaluation and compares the processing result with the processing result in the normal case. Confirmed the normal operation of each program.

In this conventional system, if the operator shortens the interval of system operation confirmation on a regular basis, the reliability of the system is improved, but the additional cost such as the personnel cost of the operator is also increased, and the operator's mistake is caused. It has drawbacks such as delay in detection of program anomaly and trouble in production work.

An object of the present invention is to automatically check the normal operation of each program between the devices in the system in a client / server model in which a plurality of programs perform processing in cooperation with each other via a communication line. Do each other,
It is an object of the present invention to provide a program status mutual monitoring system capable of improving the reliability of the system without increasing the labor cost of the operator.

[0007]

A program state mutual monitoring system according to the present invention includes a time detecting means for detecting the passage of a fixed time, and a communication destination of the communication destination in response to the time passage detection of the time detecting means. Request command generation means for requesting confirmation of program operation, response command analysis means for analyzing response from the communication destination to the request and confirming operation of the program at the communication destination, and program operation supplied from the communication destination It comprises request command analysis means for recognizing the confirmation request command, and response command generation means for responding to the communication destination the operating state of the program based on the result of the recognition.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a program status mutual monitoring system of the present invention.

The program state mutual monitoring system of this embodiment is applied to a client / server model in which two or more computers 1 as shown in FIG. 1 exist and are connected by a network.

The program state mutual monitoring system of this embodiment includes a time detecting means 3 for detecting the passage of a certain time, a request command generating means 4 for generating a command requesting the normal operation confirmation of the program on the communication partner side, A response command analysis means 5 for analyzing a response command from the other party to the request command, a request command analysis means 6 for analyzing the request command, and a response command generation means 7 for generating a response command are provided. Further, it has a business processing unit 2 for processing a specific business, a data distribution means 8 for distributing commands and business processing data, and a communication line interface 9. The time detecting means 3 generates a trigger for checking the operation of the other party's program, whereby the request command generating means 4 issues a command requesting the normal operation confirmation of the other party's program. The response command analyzing means 5 analyzes the response from the partner side to this command, and has a function of checking whether the operating state of the partner program is normal or abnormal.

Further, the request command analysis means 6 receives the command for confirming the normal operation of the program from the other side,
The response command generating means 7 has a function of determining what kind of check is requested by the other party and returns the result to the other party.

With the configuration of these systems, it becomes possible to periodically check the status of the program on the communication partner side.

Next, the operation of this embodiment will be described.

First, the time detecting means 3 detects the passage of a certain fixed time, and the request command generating means 4 receives the trigger and generates a normal operation confirmation request command of the counterpart program. The generated command is transmitted to the other party via the communication interface 9. Next, the movement of the other party will be described later. First, the state in which the response from the other party is returned to this request will be described.

The operation confirmation response command from the other party enters the communication interface 9 and is distributed by the data distribution means 8 to normal business processing data or various commands. If it is normal business processing data, it is passed to the business processing section 2, and if it is a response command, it is passed to the response command analysis means 5. The response command analysis means 5 analyzes the content of this command and determines whether the partner program is operating normally.

Next, the operation of the other party that receives the normal operation confirmation request command of the program will be described.

The other side also has the same configuration as the request side, and the request command enters the communication interface 9 and is passed to the request command analysis means 6 by the data distribution means 8. Here, the content of the received request command is analyzed to check the status of the own program. The result is passed to the response command generating means 7, and the response command is generated here. This response command is returned as a response command to the requesting side that issued the request command via the communication interface 9.

[0019]

As described above, the program status mutual monitoring system of the present invention monitors the status of the programs of the other party at regular intervals, thereby eliminating the need for an operator and drastically reducing labor costs and reliability. It has the effect of significantly improving
