[Prior art]
Processing transaction request messages (messages) input from the same terminal in the order of input has been conventionally performed. As this type of conventional technology, for example, the following technology is known (for example, Patent Document 1).
[0003]
When a message is sent from the terminal, the transaction processing system generates a new message storage buffer and stores the message in the message storage area. In addition to the message storage area, the message storage buffer includes a link in the message queue indicating the execution order of messages that can be executed by the same task (transaction execution control means), and a message group input from the same terminal. A message group link indicating the message execution order is provided.
[0004]
Thereafter, a transaction execution control means for performing transaction processing relating to the message is selected, and a message storage buffer storing the current message is connected to the tail of the message queue provided corresponding to the selected transaction execution control means. This processing is performed using a message queue link. At the same time, the message storage buffer that stores the message this time and the last message storage buffer of the message storage buffer that already stores the message from the terminal that sent the message are stored in the message group. Connect using a link.
[0005]
The transaction execution control means indicates that there is a message storage buffer whose execution order is earlier than the message storage buffer among the message storage buffers connected to the message queue corresponding to the transaction execution means. A message storage buffer that is not connected to the front of the message queue is selected. Then, transaction processing is performed according to the message stored in the selected message storage buffer.

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
[Configuration of Example]
Referring to FIG. 1, the present embodiment includes an online transaction processing system 1 that operates by program control and a terminal 2. In FIG. 1, only one terminal 2 is shown, but there are actually a plurality of terminals.
[0018]
The terminal 2 includes an execution request transmission unit 21 and a processing result reception unit 22.
[0019]
The execution request transmitting unit 21 has a function of transmitting (inputting) a plurality of transaction request messages for executing a plurality of unrelated processes to the online transaction processing system 1 in a lump (continuously). . Further, the execution request transmitting means 21 has a function of adding result notification information indicating whether or not it is necessary to return the processing result to the terminal 2 when transmitting a transaction request message. Here, the result notification information indicating that it is necessary to return the processing result is added only to the transaction request message requesting the last transaction in the series processing, and it is not necessary to return the response to other transaction request messages. The result notification information shown is added.
[0020]
The processing result receiving unit 22 has a function of outputting the processing results (normal end, abnormal end, etc.) returned from the online transaction processing system 1 to a display device or a log file (not shown).
[0021]
The online transaction processing system 1 includes an execution request receiving means 11, a transaction starting means 12, a message storage stage 13, a message queue 14 corresponding to the terminal 2, message storage buffers 15-1, 15-2,. The transaction ending unit 16, the processing result transmitting unit 17, the message extracting unit 18, the execution waiting transaction starting unit 19, the abnormal post-processing unit 20, and the recording medium K are provided. In FIG. 1, only the message queue 14 corresponding to the terminal 2 is shown, but there is a message queue for each terminal.
[0022]
When receiving the transaction request message to which the result notification information is added from the terminal 2, the execution request receiving unit 11 generates a new message storage buffer 15-i (i = 1, 2,...), And the message storage area 151 and In the result notification information storage area 152 (see FIG. 2), the transaction starting means 12 stores the function of storing the transaction request message and result notification information received this time, the information indicating the message storage buffer 15-i and the information indicating the terminal 2. It has a function to notify.
[0023]
Upon receiving the notification from the execution request receiving unit 11, the transaction starting unit 12 checks whether or not the transaction process according to the transaction request message already sent from the terminal 2 indicated by the notification is being executed. If the function is being executed, the message storage unit 13 is notified of information indicating the message storage buffer 15-i, and the message storage buffer 15-i is connected to the tail of the message queue 14, When not being executed, the transaction request message stored in the message storage buffer 15-i is passed to the corresponding business program, and a transaction process corresponding to the transaction program is started.
[0024]
The message storage unit 13 has a function of connecting the message storage buffer 15-i notified from the transaction starting unit 12 to the tail of the message queue 14.
[0025]
Message storage buffers 15-1, 15-2,... That store transaction request messages input from the terminal 2 are connected to the message queue 14 in the order in which the transaction request messages are input.
[0026]
The transaction end means 16 indicates that the end notification of the transaction received from the business program indicates “normal end”, and the result notification information stored in the message storage buffer 15-j used when starting the transaction processing is “requires reply”. In this case, after requesting the processing result transmitting unit 17 to transmit the processing result, the execution waiting transaction starting unit 19 is instructed to start the execution waiting transaction relating to the terminal 2, and the end notification is “normal”. If the result notification information stored in the message storage buffer 15-j is “reply unnecessary”, the execution waiting transaction related to the terminal 2 is started with respect to the execution waiting transaction starting means 19. If the end notification indicates “abnormal end”, the error Call the means 20, and passes the information indicating the message storage buffer 15-j.
[0027]
When the execution waiting transaction starting unit 19 is instructed to start the execution waiting transaction related to the terminal 2 from the transaction end unit 16 or the abnormal post-processing unit 20, the execution waiting transaction starting unit 19 passes information indicating the terminal 2 to the message extracting unit 18. Thus, it has a function of acquiring a message storage buffer 15- (j + 1) to be processed next, and a function of starting a transaction according to a transaction request message stored in the message storage buffer 15- (j + 1). Further, the execution waiting transaction activation means 19 calls the abnormal post-processing means 20 when the transaction activation according to the transaction request message stored in the message storage buffer 15- (j + 1) fails, and the message storage buffer 15- A function of passing information indicating (j + 1).
[0028]
When the information indicating the terminal 2 is passed from the execution waiting transaction starting means 19, the message retrieving means 18 reads the message storage buffer 15-(j + 1) connected to the head of the message queue 14 corresponding to the terminal 2 from the message queue 14. A function to connect the message storage buffer 15- (j + 2) that has been removed and connected to the head of the message queue 14, or a message storage buffer 15- (j + 1) that has been removed from the message queue 14 to start the execution waiting transaction of the request source 19 has the function of returning.
[0029]
The abnormal post-processing means 20 is called from the transaction ending means 16 and, when information indicating the message storage buffer 15-j corresponding to the abnormally ended transaction processing is passed, the message storage buffer 15 connected to the message queue 14. The message storage buffer that is a component of the series of processing to which the message storage buffer 15-j belongs is removed from the message queue 14 among-(j + 1), 15- (j + 2),... Information indicating the terminal 2 is passed to the activation means 19. Further, when the message storage buffer 15- (j + 1) corresponding to the transaction process that has been invoked and failed to be started is passed from the execution waiting transaction starting means 19, the message storage buffer 15- (j + 2) connected to the message queue 14 is passed. ), 15- (j + 3),..., The message storage buffer that is a constituent element of the series processing to which the message storage buffer 15- (j + 1) belongs is removed from the message queue 14, and then an execution waiting transaction is started. Information indicating the terminal 2 is passed to the means 19.
[0030]
The recording medium K is a disk, semiconductor memory, or other recording medium, and stores a program for causing the computer to function as the online transaction processing system 1. This program is read by a computer and by controlling its operation, an execution request receiving means 11, a transaction starting means 12, a message storing means 13, a message queue 14 corresponding to the terminal 2, The message storage buffers 15-1, 15-2,..., The transaction ending unit 16, the processing result transmitting unit 17, the message extracting unit 18, the execution waiting transaction starting unit 19, and the abnormal post-processing unit 20 are realized. .
[0031]
[Description of operation of embodiment]
Next, the overall operation of this embodiment will be described in detail with reference to the drawings.
[0032]
When the execution request transmitting means 21 in the terminal 2 inputs a plurality of transaction request messages to the online transaction processing system 1 in a batch in order to execute a plurality of processes that are not related to each other, the flowchart of FIG. The process shown in is performed. It should be noted that a plurality of transaction request messages that are collectively input to the online transaction processing system 1 are stored in the storage device (for example, a hard disk device) of the terminal 2 (not shown) in the order of input to the online transaction processing system 1. . In addition, it is assumed that a plurality of transaction request messages constituting one series of processing are stored in the storage device in a format that can be understood as constituting one series of processing. Further, it is desirable to perform the batch input process as shown in FIG. 3 when the load is small, for example, at night.
[0033]
First, the execution request transmission means 21 pays attention to the transaction request message having the first input order among the transaction request messages to be collectively input (steps A1 and A2). Thereafter, it is checked whether or not the noticed transaction request message is the last one in the series processing (step A3). If it is the last transaction request message, result notification information indicating “return required” is added and transmitted to the online transaction processing system 1 (YES in steps A4, A5, A7), and the last transaction request message is sent. If not, result notification information indicating “reply unnecessary” is added and transmitted to the online transaction processing system 1 (NO in step A4, A6, A7).
[0034]
Thereafter, the execution request transmission unit 21 pays attention to the second transaction request message in the input order (steps A8 and A2), and performs the same process as described above. The execution request transmission unit 21 repeats the above processing until there is no untransmitted transaction request message (until NO in step A3).
[0035]
The online transaction processing system 1 performs the processing shown in the flowchart of FIG. 4 every time a transaction request message to which result notification information is added is sent from the terminal 2.
[0036]
When the execution request receiving means 11 in the online transaction processing system 1 receives the transaction request message to which the result notification information is added (step B1), the execution request receiving means 11 generates a new message storage buffer 15-i, and the message storage area 151 and The transaction request message and result notification information are stored in the result notification information storage area 152 (step B2). Thereafter, the execution request receiving unit 11 notifies the transaction starting unit 12 of information indicating the message storage buffer 15-i and information indicating the terminal 2.
[0037]
Upon receiving the above notification, the transaction starting unit 12 confirms the current transaction execution state and checks whether or not transaction processing according to the transaction request message sent from the terminal 2 is being executed (step B3). .
[0038]
If there is a transaction process being executed, the newly generated message storage buffer 15-i is connected to the tail of the message queue 14 (YES in step B3, B4). On the other hand, if there is no transaction processing being executed, the transaction request message stored in the message storage buffer 15-i is passed to the corresponding business program, and the transaction processing according to the transaction request message is started (step B3 is NO, B5).
[0039]
When the transaction processing according to the transaction request message stored in the message storage buffer 15-i ends, the business program sends an end notification to the transaction end unit 16.
[0040]
When the transaction end means 16 receives the end notification (FIG. 5, step C1), it confirms the processing result of the transaction processing (step C2). Then, in the case of abnormal termination (NO in step C2), information indicating the message storage buffer 15-i used at the time of starting transaction processing is notified to the abnormal post-processing means 20 (step C10). On the other hand, in the case of “normal end” (step C2 is YES), the result notification information storage area 152 in the message storage buffer 15-i used at the time of starting transaction processing is referred to, and the processing result is returned. Is checked (step C3).
[0041]
If it is necessary to return the processing result (YES in step C3), the processing result sending means 17 is used to return the processing result to the terminal 2 (step C4), and then the next execution waiting transaction is processed. In addition, information indicating the terminal 2 is notified to the execution waiting transaction starting means 19 (step C5). On the other hand, if it is not necessary to return the processing result, the information indicating the terminal 2 is immediately notified to the execution waiting transaction starting means 19 (step C5).
[0042]
Upon receipt of this notification, the waiting transaction starting means 19 is connected to the head of the message queue 14 provided corresponding to the terminal 2 by notifying the message extracting means 18 of information indicating the terminal 2. The message storage buffer 15- (i + 1) is acquired (YES in steps C6 and C7). Thereafter, the pending transaction activation means 19 passes the transaction request message stored in the message storage buffer 15- (i + 1) to the business program and activates transaction processing (step C8). If the activation is successful (YES in step C9), once the processing is finished and the end of the transaction processing is notified from the business program, the processing shown in the flowchart of FIG. 5 is performed again. On the other hand, when the transaction process fails to start (NO in step C9), information indicating the message storage buffer 15- (i + 1) used when starting the transaction process is notified to the abnormal post-processing means 20 (step C11). ).
[0043]
The abnormal post-processing means 20 is notified of the information indicating the message storage buffer used when starting the transaction process whose processing result is “abnormal end” from the transaction end means 16 (step C10), or the execution waiting transaction When information indicating the message storage buffer used when the activation of the transaction process has failed from the activation unit 19 (step C11), the following process is performed.
[0044]
Now, for example, if information indicating the message storage buffer 15-k is notified, the abnormal post-processing means 20 pays attention to the notified message storage buffer 15-k (FIG. 6, step D1) and is stored therein. It is checked whether or not the result notification information is “return required” (step D2).
[0045]
If “reply is not required” (NO in step D2), the message storage buffer related to the abnormal series of processing is connected to the message queue 14, and thus connected to the message queue 14. Focusing on the first message storage buffer 15- (k + 1), the message storage buffer 15- (k + 1) is removed from the message queue 14 (steps D3 to D5). Thereafter, it is checked whether or not the result notification information in the message storage buffer 15- (k + 1) removed from the message queue 14 is “requires reply” (step D6).
[0046]
If “reply is not required” (NO in step D6), pay attention to the message storage buffer 15- (k + 2) connected to the head of the message queue 14 (step D3), and the same processing as described above. Process.
[0047]
On the other hand, if the determination result in step D2 is YES or the determination result in step D6 is YES, the message storage buffer related to the abnormal series of processes is connected to the message queue 14. Since there is no problem even if the transaction waiting for execution is started, the processing result transmission means 17 is used to transmit the processing result “abnormal end” to the terminal 2 and the execution waiting transaction start means. 19 is notified of information indicating the terminal 2 (steps D7 and D8). If it is determined in step D4 that there is no message storage buffer connected to the message queue 14, the processing ends.
[0048]
When the information indicating the terminal 2 is notified from the abnormal post-processing means 20, the execution waiting transaction starting means 19 acquires the message storage buffer connected to the head of the message queue 14 provided corresponding to the terminal 2. (Step C6 in FIG. 5), the transaction processing according to the transaction request message stored in the message storage buffer is started (Step C8).
[0049]
Next, the operation of this embodiment will be described using a specific example.
[0050]
FIG. 7 shows a state where a plurality of message storage buffers are connected to the message queue 14. Now, the online transaction processing system 1 is executing transaction processing according to the transaction request message stored in the message storage buffer 15-1, and the message queue 14 must be executed sequentially from the terminal 2. Message storage buffers 15-2 to 15-6 that store the transaction request messages that must be connected are connected in the order in which the transaction request messages are input. In the result notification information storage area 152 of the message storage buffers 15-1 to 15-6, “1” is stored when the processing result is required to be returned, and “0” is stored when the processing result is not required to be returned. ing.
[0051]
At this time, it is assumed that the transaction end means 16 is notified of the abnormal end of the transaction process being executed. When the transaction end result 16 is confirmed, the transaction end result 16 is “abnormal end” (step C2 in FIG. 5 is NO). Information indicating the message storage buffer 15-1 is notified (step C10).
[0052]
When the abnormal post-processing means 20 recognizes that it is unnecessary to refer to the result notification information storage area 152 in the notified message storage buffer 15-1 and return the processing result (result notification information = “0”). (NO in steps D1 and D2 in FIG. 6), in order to remove from the message queue 14 other transaction request messages in a series of processing that are composed of the transaction request message that caused the abnormality, it is connected to the head of the message queue 14. The message storage buffer 15-2 is removed from the message queue 14 (steps D3 to D5). Since the result notification information in the message storage buffer 15-2 is also “reply unnecessary” = “0”, the abnormal post-processing means 20 uses the message storage buffer 15-3 connected to the head of the message queue 14. Remove (step D6 is NO, D3). When the result notification information in the message storage buffer 15-3 is confirmed, “reply required” = “1” (YES in step D6), the process result is returned to the terminal 2 and the next activation is awaited. In order to process the transaction, information indicating the terminal 2 is notified to the waiting transaction starting means 19 (steps D7 and D8). In addition, also when step D2 is YES, the process of step D7, D8 is performed.
[0053]
As a result, the pending transaction activation means 19 uses the message retrieval means 18 to retrieve the message storage buffer 15-4 connected to the head of the message queue 14 corresponding to the terminal 2, and activates transaction processing (FIG. 5, Steps C6-C8).
[0054]
【The invention's effect】
As described above, according to the transaction batch reception sequential processing system of the present invention, a plurality of transaction request messages for executing a plurality of series of processes can be collectively input from the same terminal, thereby improving work efficiency. Can do.
[0055]
The reason is that a message queue in which multiple transaction request messages for executing a series of processes that are not related to each other are input in batch from a terminal are connected in the order of input, and a transaction request that is connected to the message queue This is because it includes execution waiting transaction starting means for sequentially extracting messages and starting transaction processing according to the extracted transaction request message.
[0056]
Further, according to the transaction batch reception sequential processing system of the present invention, when an abnormality occurs in the middle of a certain series of processes in a state where a plurality of series of processes are received (a state in which the batch input has been performed), It can be closed only to the series of processes that occurred.
[0057]
The reason for this is that if an error occurs during the execution of a transaction process, a transaction for executing a series of processes consisting of the transaction request message that caused the error among the transaction request messages connected to the message queue. This is because there is provided an abnormal post-processing means for discarding the request message and then starting the execution waiting transaction starting means.
