To do. For example, even when an application or control unit of the own computer is stopped, it is assumed that the information about the stopped state is collected and operated independently so as to transmit / receive, but a case such as power down is also conceivable. It is not always necessary to operate independently.

  Further, as shown in FIG. 3, the status information R1 includes a sender ApID that indicates an ID that is an application identifier of a computer on the data transmitter side, a receiver ApID that indicates an ID that is an identifier of an application on the data receiver computer, Operation status information indicating the operation status of the application (normally operating, stopped) and processing details (for example, data transmission, data reception, data transfer to the application are completed) Processing contents indicating that data processing is completed during data processing, load information indicating the CPU, memory, and other load information described above, a data ID that is an identifier of transmitted / received data, and a transmission / reception time of the data / Transfer time to the application / CPU load Composed of each item column of the detection time or the like time information of.

In the present specification, the state information transmitted from each computer is referred to as “R1”, and the state information transmitted from the state management computer 100 is referred to as “R2”.

  The operation status information is described in the following. The linkage module monitors the status of its own application, “normally operating” when the application is operating normally, “stopped” when the application is stopped, and will be described later. When the application is stopped and then restarted, each piece of “normally operating” information is stored. In addition, the collection and transmission function that collects and transmits status information is as follows: (1) When data transmission / reception is performed on the computer under its control, (2) When the application stops, (3) Application When the system is restarted after being stopped and operates normally, (4) every predetermined time interval (for example, 1 minute interval), (5) every predetermined time (time minute specification), any other set At the timing, the other state of the self-application is collected and transmitted to the state management computer 100 as the state information R1.

[Operation]
In the linked computer system configured as described above, the linked module units 14/24/34/44 and the like of each computer shown in FIG. 1 include status information including the above-described application operation status and other information in its own computer. Is transmitted to the state management computer 100 via the communication network 90, and the state information received by the state management computer 100 is transferred to another computer that cooperates with the application or the cooperation module unit on the transmission side. This operation will be described with reference to FIGS. 6A and 6B.

[State A]
First, the operation when the applications of both the transmitting and receiving computers are operating normally will be described. In the linked computer system in this state, as shown in the state A of FIG. 6A, when the application A (reference numeral 12) of the computer 10 operating normally transmits data to the computer 40 (step S30), the linked module of the computer 10 The unit 14 transmits the state signal R1a shown in FIG. 3 to the state management computer 100 as a transmission report (step S31).
The cooperation module unit 44 of the computer 40 that has received the data from the application A (step S32) transmits the status information R1d storing the received data in the processing content to the state management computer 100 and reports the reception (step S33). )I do.

  The state management computer 100 that has received the state information R1a and R1d from the computers 10 and 40 refers to the application cooperation table unit 111 and searches for the application identifier of the computer that cooperates based on the originating ApID of the state information R1a. (Step S35), the application A of the sending computer 10 and the application D of the computer 40 cooperate, and the data is sent from the application A to the application D, and the application D receives the data from the application A. That is, it is determined that the status information R1a by the calling application and the status information R1d of the receiving application correspond to each other, and data transmission / reception is normally completed between the cooperating applications. At this time, the state management computer 100 according to the present embodiment generates state information R2 including the receiving-side application identifier included in the state information R1a and the processing content (processing progress information) included in the state information R1d, and this state information R2 Is transmitted to the cooperation module 14 of the application A (step S36).

The cooperation module 14 of the transmission-side computer 10 that has received this status information R2 (step S39) includes the status information including information on the transmission-side ApID “d” and the “processing content” received from the reception-side cooperation module 44. By receiving R2, it can be determined that the data transmitted by itself is normally received by the receiving computer 40.
Furthermore, the cooperation module 44 of the receiving computer 40 according to the present embodiment performs data processing when, for example, the control unit of the computer 40 transfers received data to the own application D, and when the application D is processing the transferred data. When completed, state information R1d including these states in the processing content is reported to the state management computer 100 (step S37, step S38), and the state management computer 100 that receives this reports the processing content to “data transfer” / “ By transmitting the status information R2 rewritten to “data processing in progress” / “data processing complete” to the data transmission side computer 100, the transmission side application 12 can determine the data processing process in the reception side application. In the above-described example, it is determined in step S35 that the applications A and D are linked. However, since the linkage information R1a from the transmission side application includes the transmission side and reception side application identifiers, In step S35, step S35 is not always necessary. The processing in the above-described steps S37 and S38 is the same in the examples shown in other states B to E described later.

[State B]
Next, the operation when the application 42 is stopped when the application 12 of the computer 10 tries to send data to the application 42 will be described. In the linked computer system in this state, as shown in the state B of FIG. 6A, when the application A (reference numeral 12) of the computer 10 transmits data to the computer 40 that has stopped (step S40), the linked module unit 14 of the computer 10 3 transmits the status signal R1a shown in FIG. 3 to the state management computer 100 as a transmission report (step S41), but the computer 40 is receiving a report (step S43) because the computer 40 is stopped. ) Cannot be performed.

At this time, the control unit 110 of the state management computer 100 refers to the application cooperation table unit 111, and the applications C and D (reference numerals 32 and 42) cooperate with the application A (reference numeral 12) on the transmission side. In addition, the abnormal state caused by the transmission of data from the application A to the application D and the fact that the application D has not received the data from the application A within a preset threshold time is determined (step S51), and the computer 10 is linked. The receiving side application identifier included in the state information R1a received from the module 14 and the determined abnormal state are generated in the “processing content” as processing progress information, and the state information R2 is generated and transmitted to the application A (step S46). To work.
Upon receiving this status information R2 (step S49), the cooperation module 14 of the originating computer 10 receives the status information R2 storing its own originating side ApID “a” and the other side originating side ApID “d”, and By determining that the “processing content” is “abnormal state”, the fact that the data transmitted to the application D by itself has not been received normally (the transmitted data is lost or the partner computer / application is stopped) Can be determined.

  On the other hand, the state management computer 100, which has determined that the application D has not received data from the application A within the preset threshold time, refers to the failure report destination table unit 123 and reports the failure. It is operated so as to report to the e-mail or other means (step S50).

  In this example, the reason that the notification to the originating computer and the administrator is suspended for the threshold time in step S51 is that the data transfer time may be delayed due to the communication network being busy, and the busy state is regarded as computer shutdown. This is to prevent misjudgment. Further, the process state information in the present embodiment is stored in the storage unit 113 illustrated in FIG. 1, so that an administrator who operates the computer 800 refers to the state information stored in the storage unit 113, and there is a failure. You can know the computer and application that occurred. Note that this state B is the same in the case of data lost in which data is lost during data transfer due to some cause even though the receiving-side application is operating normally.

[State C]
Next, in a state where the application D (reference numeral 42) of the computer 40 is preparing to transmit data to the application A (reference numeral 12) of the computer 10, the operation at the time of high load on the computer 10 on the data receiving side is performed. explain. In the linked computer system in this state, as shown in the state C of FIG. 6B, the linked module unit 14 of the computer 10 includes the load information of the own computer (high load in this example) at the timing of the predetermined time interval described above. The status information R1a (the receiving-side ApID is blank) is transmitted to the status management computer 100 (step S60).
The state management computer 100 that has received the state information R1a refers to the high load etc. determination table 112 based on the load information included in the state information R1 to determine whether the load is higher than the threshold of the computer 10 (step) Next, S61) is performed, and all other application IDs linked to the application A of the computer 10 are searched by referring to the application linkage table unit 111 based on the calling side ApID included in the state information R1a (step S62).

  In the case of this example, since the CPU of the computer 10 has a higher load than the threshold set in the high load etc. determination table 112, the state management computer 100 refers to the state information R1a received from the computer 10, and Generate status information R2 in which “a” is stored in “ApID” and “abnormal status” due to a high load status is stored in “processing content”, and the status information R2 is transmitted to other linked applications searched in step S62 described above ( Step S63).

  The cooperation module unit of the computers 30 and 40 determines that the “receiving side transmission ApID” of the received state information R2 is “a” and the “processing content” is “abnormal state”, whereby the receiving side ApID “a "A" is determined to be in an abnormal state, the data transmission / reception process for the application A of the computer 10 is suspended (steps S64 and S66), and each of the computers 30 and 40 performs these steps for a predetermined time. It operates to stand by (steps S65 and S67). The waiting time may be set in advance by an instruction from the state management computer 100.

On the other hand, the state management computer 100 according to the present embodiment searches the failure report destination table unit 123 for an administrator to report, together with the above-described abnormality report of the originating application with respect to the linked application, and searches the management It operates so as to report a trouble (step S68) to the person by means of e-mail or the like.
In the above example, the case where the computer is heavily loaded has been described. However, the state management computer 100 according to the present embodiment is not limited to the above example, and the application A is stopped or the application A is restarted. The same operation is performed, and the state information R2 in which an abnormal state including that the application A is stopped or a normal state including that the application A is restarted is generated and linked in the “processing content”. Operates like sending to other applications.

  Through these series of operations, when the receiving computer or application is in a high load / stopped / restarted state, the linked computer system according to the present embodiment changes the status of the receiving computer or the like of the other sending computer. By reporting to the application, it is possible to temporarily hold the processing of the cooperation destination computer and the application and report the status of the receiving computer to the administrator.

[State D]
When the application C (reference numeral 32) of the transmission-side computer 30 in the state C described above generates a data transmission process for the application A (reference numeral 12) of the computer 10 (step S10), the cooperation module of the computer 30 according to the present embodiment Since 34 is on standby in the above-described step S65, it operates to maintain the suspension of data transmission (step S11).
With this operation, the linked computer system according to the present embodiment can prevent the occurrence of a timeout error when data is transmitted, for example, because the computer 30 maintains the suspension of data transmission to the computer 10.

[State E]
Next, an operation when the load factor of the receiving computer 10 is reduced in the state D described above will be described. In this case, the cooperation module 14 of the computer 10 transmits the state information R1a including the load information in which the load factor is reduced to the normal state to the state management computer 100, and the state management computer 100 that has received the state information R1a Then, referring to the application cooperation table unit 111, search for other computers and applications that cooperate with the receiving computer 10 (step S25), and then refer to the high load determination table 112 that the load factor has decreased below the threshold. Based on the determination result, status information R2 in which the normal status is stored in the “processing content” which is the processing progress information shown in FIG. 3 is generated, and the generated status information R2 is linked to another computer 30. And 40, each computer releases the standby state based on the state information R2 (step S27). It operates as.

  By this series of operations, the linked computer system according to the present embodiment reports the fact that the load factor of the application, which was a high load on the receiving side, has been reduced to the normal state, and reports it to the linked module of the linked sending computer. For example, the data transmission standby in step S11 in the state D can be canceled, data can be transmitted to the computer 10 on the receiving side, and the business process can be continued.

  In the above-described embodiment, the case where the receiving computer 10 is heavily loaded has been described. However, the present invention is not limited thereto, and for example, when the application of the computer 10 is stopped and recovered from the stop, the same applies. It is also possible to report the stop or recovery of the receiving side application to the sending side application. Further, when the linked computer system according to the present embodiment determines the above-described abnormal state, for example, by displaying this on the display unit (or displaying with a flag), the display color of the application name is different from that of other normal applications. The system administrator may be configured to warn.

  In the embodiment, an example in which one application is installed in one computer has been described. However, the present invention is not limited to this, and a plurality of applications may be installed in one computer.
