Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of adding or changing functions to an existing information processing system without changing a business program of an existing center in an existing information processing system.

[Conventional technology]

Conventionally, in an information processing system consisting of a terminal and a center, when adding or changing functions to a business program,
The center program had to be remodeled. Even when an information processing device (front-end processor) is added for load distribution between the terminal and the center, it is necessary to remodel the program on the center side.

A related technique of this type is disclosed in, for example, JP-A-63-138439.

[Problems to be solved by the invention]

The conventional technique has a problem that, in the existing information processing system, when a function is added or changed to a business program, the center side program is remodeled.

A specific example will be described below. In FIG.
12, an existing computer system 5, a business program group 8 in the existing computer system 5, and a data file 6 on the existing computer system 5. In such a system, the existing computer system 5 receives a message requesting processing from the terminal 12 through the line 18, and the business program group 8 analyzes the contents of the processing request message and refers to and updates the data file 6. Then, the processing result is returned to the terminal 12.
In an information processing system such as a bank's online service, the size of the business program group 8 on the existing center is on the order of several M steps to several tens M steps.
Adding and changing functions to the business program group 8 requires a great deal of man-hours. In addition, since the data file 6 of the existing center 5 has a large capacity, it takes time to refer to and update the data file 6, and the response time to the terminal 12 becomes longer.

An object of the present invention is to add or change functions without modifying a center-side program of an existing information processing system.

[Means for solving the problem]

In order to achieve the above object, the present invention adds an information processing device between a terminal and a center, and supports an additional function and a change function in the information processing device. At this time, the additional information processing apparatus is connected to the center by a conventional center-terminal interface, and does not require modification of the program of the existing center.

Further, in order to support functions in the additional information processing apparatus, it is necessary to share information such as a database existing in the existing center with a part of the center. Therefore, it is necessary to update the shared information in synchronization with the center,
After updating the data file in the additional information processing device, the updated information is stored in the additional information processing device, and the information update of the existing center is performed based on the stored information in the additional information processing device.

If an error occurs due to a line failure or the like when updating the information of the existing center with the accumulated information, an inquiry is made to the existing center in the additional information processing device without notifying the terminal user, and the processing is completed. If not, retry.

Further, if an error occurs when updating the information of the existing center with the stored information, the information that has the same information as the errored information in the already stored information will be suppressed from being transmitted to the existing center. It is.

[Action]

The message input from the terminal is received by the additional information processing device, the information in the additional information processing device is updated, and an update completion response is returned to the terminal. Further, this update information is accumulated. After that, the update information is read, converted into a message format according to the protocol between the conventional terminal and the existing center, and transmitted to the existing center. As a result, the existing center does not need to perform processing conscious of the message from the additional information processing device, and it is not necessary to modify the program of the existing center. Also, the turnaround time seen from the terminal is reduced.

When the accumulated information is read, and the message transmitted to the existing center becomes an error due to a line failure or the like and the processing result in the existing center is unknown, the additional information processing apparatus transmits an inquiry message of the processing result to the existing center. If the processing has been completed, the next processing is performed. If the processing has not been completed, the message in which an error has been encountered is transmitted again. This eliminates the need for retry processing for error messages that was conventionally performed by terminal users.

When the stored information is read out and the message sent to the existing center has an error at the existing center due to the content of the message, information having the same content as the error message may have accumulated in the stored information. By suppressing the message, the occurrence of an error message can be prevented.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In this embodiment, as shown in FIG. 1, an information processing device 4 is added between the terminal 1 and the existing computer system 5, a business program group 7 is constructed on the additional information processing device 4, Add or change functions for.
The data file 2 in the additional information processing device 4 shares part of the contents of the data file 6 in the existing computer system 5. Here, "shared" means that the shared data in the data file 2 manages data on a national scale, for example, while the shared data in the data file 2 manages data on a prefecture scale. Constitutes a partial copy of the data file 6.

As a specific example of the function change, for example, in the business program A of the existing computer system 5, a series of business is completed by exchanging data with the terminal 12 a plurality of times. In some cases, data exchange with the terminal 1 may be completed only once by the business program A 'and the data file 2. That is, a message from the terminal 1
The business program A 'receiving the 13 refers to the data file 2 and updates the data file 2 as necessary. Thereafter, as will be described in detail below, the update information is sent to the computer system 5, and the corresponding information of the data file 6 is updated.

As a specific example of the function addition, data file 2
Has new data not in the data file 6,
By adding a business program D that is not in the business program group 8 of the existing computer system 5 and communicating between the terminal 1 and the business program D in the additional information processing device 4,
A new service that does not exist between the terminal 12 and the existing computer system can be provided.

The updated records which are shared with the data file 6 among the records in the data file 2 need to be reflected in the data file 6. Further, the processing of the business program A in the existing computer system 5 can be partially replaced by the processing of the business program A 'in the additional information processing apparatus 4, but the processing of outputting the form 11 with the data file 6 of the existing computer system 5 as input. Therefore, the update information and additional information in the information processing device 4 must be transmitted to the computer system 5 for this purpose. In the reflection, when the business program A ′ updates the data file 2 between the terminal 1 and the business program A ′, the update content is taken over by the relay program 19, and the relay program 19 temporarily stores the updated content in the storage file 3. Thereafter, the relay program 19 reads the record 15 in the storage file 3 and is exchanged between the conventional terminal 12 and the business program A on the existing computer system 5 based on the record 15 and the corresponding record in the data file 6. The message is converted into a message 22 in the current format and transmitted to the existing center 5 through the line 17. The business program A performs a process of updating the data file 6 and outputting necessary output information to the form 11 as before. In this way, the update of the data file 2 can be reflected on the data file 6 without modifying the business program A.

Next, FIG. 2 shows the flow of processing of the relay program 19. When the business program A 'receives the message 13 from the terminal 1, the data file 2 is updated. Thereafter, the business program A ′ takes over the contents of the message 13 relating to the update to the relay program 19. The relay program 19 analyzes the electronic message 13 from the terminal and extracts information (business code, telephone number) for creating the storage record 15. A storage record is created from the extracted information, written in a storage file, and a response message is transmitted to the terminal 1. Next, the storage record 15 in the storage file 3 is read, and the same transmission message format as the message 22 between the conventional terminal 12 and the existing computer system 5 is used. The contents of the storage record 15 and the telephone number in the storage record 15 are used as key information. Is created by the corresponding record of the data file 2 searched. After that, the message 22 is transmitted to the existing computer system 5. In the above embodiment, the message 22 was created from the accumulated record 15 created from the content of the message 13 related to the update and the corresponding record in the data file 2. However, if sufficient space can be secured as the accumulated file 3, the update May be stored as the accumulated record 15.

Next, FIG. 3 shows an embodiment of the retry (retransmission) processing of the relay program 19 when a failure occurs in the line 17 between the additional information processing apparatus 4 and the existing computer system 5, and the flow of the processing of the relay program. Will be described with reference to FIG.

The relay program 19 in the additional information processing device 4 reads the storage record 15 from the storage file 3, assembles it as a message 22, and sends it to the existing computer system 5. When the line failure 30 occurs on the line 17 at the time of transmission or reception of the transmission result, the communication control program 23 in the additional information processing device 4 detects
The failure notification 24 is sent to the relay program 19. When the failure notification 24 is issued, it is unknown whether the processing on the existing computer system 5 has been completed and the data file 6 has been updated. So the message that relay program 19 encountered a failure
An inquiry message 28 for inquiring the processing result of step 22 is created and transmitted to the existing computer system 5. The inquiry message 28 is processed by the inquiry program 29 of the existing computer system 5, refers to the data file 6 for the customer information of the designated telephone number, and the result is notified to the relay program 19 as the inquiry result 27. The relay program 19 determines whether the customer information 27 in the inquiry result matches the customer information at the time of the previous transmission. If they match, it is determined that the line has been updated and the line failure has occurred during the reception of the transmission result, and the relay program 19 determines that the next storage file 3
Is read. If they do not match, a line failure occurs during transmission from the additional information processing device 4 to the existing computer system 5, and the data file 6 in the existing computer system 5
Is determined not to have been updated, and the same message as the message 22 that encountered the line failure is transmitted to the existing computer system 5. By realizing the retry process, the process conventionally performed manually by the person operating the terminal 12 can be automatically performed, and operability can be improved.

Next, an embodiment of the message regulation process will be described with reference to FIG. 5, and a flow of processing of the relay program in the message regulation process will be described with reference to FIG.

If transaction processing for the same identification code, for example, the same telephone number is performed a plurality of times from the terminal 1, there may be a plurality of storage records 15 having the same telephone number in the storage file 3. In such a state, the relay program 19 reads the leading storage record 15-1, converts it into a message format handled by the existing computer system 5, and transmits it to the existing computer system 5. In the processing in the existing computer system 5, when the telephone number in the message transmitted from the additional information processing device 4 is not present in the data file 6, etc., the existing computer system 5 notifies the relay program 19 as a failure notification. Notice. It should be noted that a failure notification due to a line failure or a failure notification due to a business program process in an existing computer system is classified according to the failure information in the failure notification. When the relay program 19 receives the failure notification 24, the relay program 19 registers the telephone number in the failure notification as the restriction information 34. Next, when the next storage record 15-2 in the storage file 3 is read, the relay program
Step 19 determines whether the telephone number in the storage record 15-2 matches the telephone number in the regulation information 34. If they match, message transmission processing for the storage record 15-2 is suppressed, and if they do not match, message creation and message transmission are performed. With this method,
The failure notification from the existing computer system 5 can be generated only for the first record of the stored records having the same identification code.

〔The invention's effect〕

According to the present invention, functions can be added or changed to business programs in a large-scale system without modifying existing business programs. Can be improved.

In addition, the retry process for the failure notification can reduce the intervention operation of the terminal operator, so that the operation can be automated.

In addition, since the message having a high error probability is excluded from the transmission schedule by the message regulation process, there is an effect of suppressing the generation of useless transmission messages.
