2. Description of the Related Art Japanese Patent Application Laid-Open No. 07-225707 discloses a method and apparatus for testing an application operating as a client with respect to a database management system. ) Is provided to diagnose the operation of the test target process. In the case of this publication, it is difficult to distinguish between a failure in the test target process, a failure between the diagnosis processes, and a failure in the diagnosis process. In addition, Japanese Patent Application Laid-Open No. 09-2514
Japanese Patent Application Laid-Open Publication No. 14-142, discloses that when a local system requests data to a remote system, it is determined whether or not the requested information exists in the local system's own cache. It is described that data is taken in from this document, but in the case of this publication, it cannot be confirmed that its own information is the latest.

[0003] Japanese Patent Application Laid-Open No. 07-182885 discloses that communication is of the exchange type, and that a diagnostic device is positioned as a device of a third party separate from a client and a server that actually communicate. Therefore, interactive communication means is required between the client and the diagnostic device and between the diagnostic device and the server. Further, Japanese Unexamined Patent Publication
JP-A-108584 discloses that a client diagnoses the state of a server based on information sent from the server.

As described above, various attempts have been made to diagnose an online system in addition to a client-server system. At the time of such a diagnosis, in a client-server system, an online system, or the like, when a failure occurs, in order to investigate the location of the failure, a survey tool must be incorporated in the server system for each investigation for each management means. Was indispensable.

[0005]

In such a conventional system, when installing a device, it is necessary to disconnect a communication line from the server device or to stop the management means of the server system. There is a problem in that when it is incorporated into a server, it affects server operations. In addition, since a failure investigation tool is often different for each management means, a person in charge of the failure investigation needs a wide variety of knowledge. Further, for the same reason as the above two problems, a time constraint is added to the investigation work, so that it takes a long time for the failure investigation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to diagnose a failure at any time without interrupting the operation of the server system, and to quickly investigate the failure of the server system. It is another object of the present invention to provide a network server diagnostic system that improves the operation rate of a server system.

[0007]

In order to achieve the above object, a network server diagnostic system according to the present invention transmits a diagnostic message to a server system, and transmits the diagnostic message within a predetermined time after transmitting the diagnostic message. When no response message arrives from the server, or when the response message arrives within the predetermined time, but the arrived response message is not the expected value, the diagnostic processing management that recognizes that the server system has failed. In the client system having the means and the server system, provided at a position corresponding to a business message processing unit, when the business message processing unit receives the diagnostic message, it is delivered by the business message processing unit and the diagnostic message corresponds to the self. If so, the response message is transmitted to the client system, and the diagnostic message does not correspond to itself. Diagnostic message management means for transmitting a diagnostic message received in the subsequent stage in the case, characterized in that it comprises a communication channel and that the line connecting the server system and the client system.

According to the present invention, the client system transmits the diagnostic message to the business message processing unit of the server system via the communication path, and when the business message processing unit receives the diagnostic message, it responds to the corresponding business message processing unit. The diagnostic message is transferred from the position to the diagnostic message management unit at the same position, and if the diagnostic message management unit does not correspond to itself, the received diagnostic message is transmitted to the subsequent diagnostic message management unit. If the received diagnostic message is a diagnostic message corresponding to itself, the diagnostic message management unit transmits a response message to the client system through a communication path. If the response message does not arrive within a predetermined time after the transmission of the diagnostic message, or if the response message does not reach the expected value even if the response message arrives, the client system diagnoses the diagnostic message using the diagnostic message. It recognizes that an abnormality has occurred in any of the diagnostic message management means at the stage before the management means.

Next, the operation of the first embodiment will be described in detail with reference to FIGS. FIG. 2 is a flow chart showing a processing procedure of the diagnostic processing management means 2, and FIG. 3 is a flowchart showing a processing procedure of the diagnostic message management means 5. First, as shown in the flowchart of FIG. 2, the diagnostic management unit 24 transfers the diagnostic operation instruction information given from the input / output device 6 to the diagnostic control unit 22 in step 22-2 in step 22-1. Based on the diagnostic operation instruction received from the diagnostic management unit 24, the diagnosis control unit 22 determines the line management unit 41 which is the foremost management unit of the business message processing unit 4.
Is used as the return position information, a diagnostic message is generated in step 22-3.

Next, the diagnosis control means 22 executes step 22
Step 4 sets the diagnostic message return time limit at -4.
After storing the expected value of the response message with respect to the diagnostic message in 2-5, the diagnostic message is transmitted in step 22-6.
Hand over to 1. Next, the diagnosis control means 22 executes step 2
The reception of the response message is waited for the diagnostic message return limit time set in 2-7. If a response message is received within the diagnostic message return time limit, the content of the message is compared with the expected value stored in step 22-5 in step 22-8, and if the result of the comparison is correct, the diagnosis is made in step 22-9. That the management unit of the return position of the business message processing unit 4 that has performed the normal operation is operating normally.
Hand over to

Further, the diagnosis control means 22 executes step 2
In step 2-11, the communication management unit 42, which is the next management unit of the business message processing unit 4, is set as the return position information,
In step 12, the information is compared with the diagnostic operation instruction information passed from the diagnostic management unit 24, and the above-described processing is repeated until the diagnosis is completed. On the other hand, if the diagnostic message return time limit is exceeded in step 22-7 or if the comparison result is different from the stored expected value in step 22-8, step 22-1 is executed.
The management unit of the return position of the business message processing unit 4 that has performed the diagnosis at 0 recognizes that the state is abnormal or an exceptional state, and passes the result to the diagnosis result storage unit 23.

Next, the operation of the diagnostic message processing means 5 will be described with reference to the flowchart of FIG. 3, taking the communication management diagnostic message management means 52 of the diagnostic message management means 5 as an example. First, in step 42-1, the communication management unit 42, which has received the message from the line management unit 41, determines the type of the received message in step 42-2, and in the case of a diagnostic message, receives the message in the communication management diagnostic message management unit 52. Hand over the sent message. Next, the communication management diagnostic message management unit 52 determines whether the diagnostic message for the communication management unit 42 or the diagnostic message for another management unit is based on the message return position information of the diagnosis message received from the communication management unit 42 in step 52-1. Judge.

Next, in the case of a diagnostic message to the communication management means 42, a response message is processed and created by a predetermined process based on the diagnostic message in step 52-2, and the line of the communication management means 42 is processed in step 42-6. The response message is delivered to the message delivery process to the management means 41 and delivered to the line management means 41 as a message. If it is determined in step 52-1 that the message is a diagnostic message for another management unit, the message is not processed into a message.
In step 42-4, the diagnostic message is delivered to the message delivery process of the communication management unit 42 to the transaction management unit 43, and is delivered to the transaction management unit 43 as a message.

If it is determined in step 42-2 that the message has no subsequent processing, the communication management unit 42 is determined in step 42-5.

In step 42-2, in the case of a message to the subsequent management means, a predetermined process for the message of the subsequent management means is performed in step 42-3, and the message is sent to the transaction management means 43 in step 42-4. hand over.

Next, the operation of the first embodiment will be described using a specific example with reference to the operation explanatory diagram of FIG. As shown in FIG. 4, the return position information is "1" in the line management unit and "2" in the communication management unit in the read-only memory (neither is shown) of each diagnostic message management unit. It is set as follows. Now
In a state where an abnormality has occurred in the communication management unit 42 of the device under diagnosis 3, the input / output device 6
It is assumed that a diagnosis request for “communication management means” has been input.

The diagnosis management means 24 is a "communication management means".
With reference to the read-only memory, the return position information is quantified to “2” and passed to the diagnosis control means 22. The diagnostic control unit 22 first sets “1” to the return position information and the expected value of the return message content, sets 30 seconds to the diagnostic message return time limit, and then transmits the diagnostic message to the device to be diagnosed through the communication path A. 3 (steps 22-1 to 22-6 in the flowchart).
The line management unit 41 included in the business message processing unit 4 of the device under diagnosis 3 passes the message to the line management diagnosis message management unit 51 because the received message is a diagnostic message (steps 42-1 and 42-2). .

The line management diagnostic message management means 51 compares the return position information in the diagnostic message with the own management means information in its own read-only memory. Since both are equal to "1", the response message is processed. The telegram is returned to the diagnostic device 1 via the communication path A via the line management means 41. Diagnosis control means 2
In the case of No. 2, after receiving the response message from the device under diagnosis 3, "1" is added to the return position information, and the result is compared with the return position information passed from the diagnosis management means 24. The diagnostic message is transmitted again (step 22
-11, 22-12).

The line management diagnostic message management means 51 of the device under diagnosis 3 compares the return position information in the diagnostic message with its own management means information in its own read-only memory. Therefore, the diagnostic message is delivered to the communication management means 42, which is the management means at the subsequent stage, via the line management means 41 (step 42-6). The communication management unit 42 cannot process the diagnostic message because of the failure, and cannot return a response message to the diagnostic device 1. Diagnosis control means 22
Is set as the diagnostic message return time limit 3
While waiting for a response message for 0 seconds, no response message is returned, it is determined that a failure has occurred in the management means in the device under diagnosis 3 indicated by the current return position information (step 22-7), and diagnosis is performed. Communication management means 4 in result storage means 23
The diagnosis result is notified as the abnormal information in Step 2 (Step 2)
2-10).

As described above, in the first embodiment, the diagnostic device is incorporated in the client-server system, and the diagnostic means for responding to the diagnostic request from the diagnostic device in advance for each management means constituting the server system. Since the message response means is incorporated, failure diagnosis can be performed at any time without interrupting the operation of the server system. As a result, the failure investigation of the server system is promptly performed, and the operation rate of the server system is improved.

Next, another embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a block diagram showing the configuration of the second embodiment according to the present invention. This figure 5
In the description of the configuration, in order to avoid redundant description with FIG. 1, the same parts as those in FIG. As apparent from a comparison of FIG. 5 with FIG. 1, FIG. 5 is different from the embodiment shown in FIG. 1 in that a periodic diagnosis issuing means 25 is provided in addition to the configuration of the embodiment.

The periodic diagnosis issuing unit 25 monitors the timer by itself, and issues a diagnosis request to the diagnosis management unit 24 at regular intervals up to the last stage of the device to be diagnosed. In the second embodiment, since the diagnostic processing is automatically repeated periodically, there is an effect that the failure of the device under diagnosis 3 can be found earlier. Next, the operation of the second embodiment according to the present invention will be described with reference to the operation explanatory diagram of FIG.

In FIG. 6, the return position information that has been digitized in the previous example is represented using an arbitrary character string. The return position information is held as a table called a management means table on a read-only memory shared by each means of the diagnosis processing management means 2. First, the diagnosis management unit 24 obtains a character string representing the return position information from the management unit table based on the diagnosis instruction operation information input from the input / output device 6. Next, the diagnosis management means 24 delivers the return position information to the diagnosis control procedure 22, and issues a diagnosis instruction. The diagnosis control unit 22 obtains return information “line” indicating the line management unit, which is the first data of the management unit table (step 22-3).

Next, the diagnostic control means 22 issues a diagnostic message transmission request to the diagnostic message sending / receiving means 21 and waits for a response message to be received for the return time limit (step 22).
-6). Each diagnostic message processing unit included in the business message processing unit 4 of the device under diagnosis 3 also has its own management unit information having the same character string as the character string set in the previous management unit table. Now, since the return position information transmitted from the diagnostic device 1 is “line”, the line management diagnostic message management unit 51 creates a response message because the line management diagnostic message management unit 51 matches the own management unit information. (Step 52-
2). Upon receiving the response message, the diagnosis control unit transmits the second data “communication” in the management unit table as the return position information to the device to be diagnosed because the response message is expected (step 22-12, 22-6). The second embodiment differs from the first embodiment in that an arbitrary character string is used for the return position information.

[0038]

As described above, according to the present invention, the diagnostic message transmitted from the client system is received by the business message processing unit of the server system, and the diagnostic message is transferred from the business message processing unit to the diagnostic message management unit. If the management unit does not correspond to its own diagnostic message, it sends it to the subsequent stage.If it corresponds to its own, it sends a response message to the client system.If the response message is not sent for any time, it is sent. Even if the content of the response message is different from the expected value, the client system diagnoses that an error has occurred in the server system. Therefore, failure diagnosis is performed at any time without interrupting the operation of the server system. be able to. Along with this, fault diagnosis of the server system can be speeded up, and the operating rate of the server system can be improved.
