Description

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

[Conventional technology]

Conventionally, in an information processing system consisting of a terminal and a center, when adding a function or changing two functions to five business programs, it was necessary to modify the program on the center side. Also,
Even when adding an information processing device (front-end processor) between the terminal and the center to distribute the load, it was necessary to modify the program on the center side.

Note that related techniques of this type include, for example, Japanese Patent Application Laid-Open No. 138439/1983.

[Problem to be solved by the invention]

The above conventional technology has a problem in that in an existing information processing system, when adding nine functions to a business program, the program at the center must be modified. 1
2. Existing computer system5. It consists of 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 accepts a message requesting processing from the terminal 12 through the line 18, the business program group 8 analyzes the contents of the processing request message, and references and updates the data file 6. and returns the processing results to the terminal 12. In information processing systems such as banks' online services, business programs on existing centers8
The scale is on the order of several M steps to several 10 M steps, and adding or changing one function to the business program group 8 requires a large number of man-hours. Furthermore, since the data file 6 of the existing center 5 also has a large capacity, it takes time to refer to and update it, which causes a problem that the response time to the terminal 12 becomes long.

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

[Means to solve 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 additional functions and changing functions within this information processing device. At this time, the additional information processing device is connected to the center through the conventional center-to-terminal interface, making it unnecessary to modify the existing center program.

Further, in order to provide functional support within the additional information processing device, it is necessary to share some information such as a database existing in the existing center with the center.

Therefore, when updating shared information, it is necessary to update it 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 update information is stored in the additional information processing device. Information is updated using the information stored in this additional information processing device.

Additionally, if an error occurs due to a line failure when updating the information of an existing center using accumulated information, the additional information processing device queries the existing center and completes the process without notifying the terminal user. If not, try again.

Furthermore, if an error occurs when updating the information of an existing center using stored information, if the already stored information has the same information as the information that caused the error, it will be inhibited from being sent to the existing center. It is.

[Effect]

The additional information processing device receives the message input from the terminal, updates the information in the additional information processing device, and returns an update completion response to the terminal side. Furthermore, this updated information is accumulated. After that, the update information is read out, converted into a message format that follows the protocol between the conventional terminal and the existing center, and sent to the existing center. As a result, there is no need for the existing center to perform processing that takes into account the message from the additional information processing device, and there is no need to modify the existing center's program. The turnaround time seen from the terminal is also shortened.

When the stored information is read and the message sent to the existing center causes an error due to a line failure or the like and the processing result at the existing center is unknown, the additional information processing device sends an inquiry message for the processing result to the existing center. When the processing is completed, the next processing is performed, and when the processing is not completed, the message in which the error occurred is sent again. This eliminates the need for retry processing for error messages, which was conventionally performed by terminal users.

If the stored information is read and a message sent to an existing center causes an error in the existing center due to the contents of the message, there is a possibility that information with the same content as the error message remains in the stored information. By suppressing the message, it is possible to prevent the error message from occurring again.

〔Example〕

Hereinafter, one embodiment of the present invention will be described using drawings in which an information processing device 4 is added between the existing computer systems 5, a business program group 7 is constructed on the additional information processing device 4, and functions for the center-side business programs are explained below. Added 9 functional changes. 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, for example, data file 6 manages nationwide data, while shared data in data file 2 manages prefecture-wide data.
This means that the shared data in data file 2 constitutes a copy of a portion of data file 6.

As a specific example of a function change, for example, in the business program A of the existing computer system 5, a series of business tasks was completed by exchanging data with the terminal 12 multiple times, but instead of Data exchange with terminal 1 is performed by business program A' and data file 2.
Sometimes it can be done in one session. In other words, message 1 from terminal 1
The business program A' that received the data file 3 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 correspondence information in the data file 6 is updated.

Also, as a specific example of adding functions, data file 2 has
Add new data that is not in the data file 6, add a business program D that is not in the business program group 8 of the existing computer system 5, and communicate between the terminal 1 and the business program D in the additional information processing device 4. By doing so, it is possible to provide a new service that does not exist between the terminal 12 and the existing computer system.

Note that data file 6 is a record in data file 2.
Updated records that are shared with the user need to be reflected in the data file 6 as well. Furthermore, the processing of the business program A of the existing computer system 5 can be partially replaced by the processing of the business program A' in the additional information processing device 4;
Since the process of outputting the form 11 using input data cannot be replaced, the updated information and additional information in the information processing device 4 must be transmitted to the computer system 5 for this purpose as well. For reflection, when the business program A' updates the data file 2 between the terminal 1 and the business program A', the updated contents are handed over to the relay program 19, and the relay program 1
9 is temporarily stored in storage file 3. After that, the relay program 19 reads the record 15 in the storage file 3, and based on the record 15 and the corresponding record in the data file 6, the conventional terminal 12 and the existing computer system
It is converted into a message 22 in the format exchanged between the business programs A above, and sent to the existing center 5 through the line 17. Business program A is data file 6 as before.
At the same time, necessary output information is output to the form 11. In this way, updates to the data file 2 can be reflected in 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, it updates the data file 2. Thereafter, the business program A' takes over the contents of the message 13 related to the update to the relay program 19. The relay program 19 analyzes the message 13 from the terminal and extracts information (business code, telephone number) for creating the storage record 15. Create a storage record from the extracted information, write it to the storage file,
Sends a response message to terminal 1. Next, the storage record 15 in the storage file 3 is read, and the transmission message format is the same as the message 22 between the conventional terminal 12 and the existing computer system 5, and the contents of the storage record 15 and the telephone number in the storage record 15 are used as key information. It is created using the corresponding record of data file 2 searched as . Thereafter, the message 22 is transmitted to the existing computer system 5. In the above embodiment, the message 22 is created from the storage record 15 created from the contents of the message 13 related to the update and the corresponding record in the data file 2. However, if sufficient space can be secured for the storage file 3, the update is possible. The entire message 13 related to the above may be stored as the accumulation record 15.

Next, a relay program 19 for when a failure occurs in the line 17 between the additional information processing device 4 and the existing computer system 5
An embodiment of the retry (retransmission) process will be explained in FIG. 3, and the process flow of the relay program will be explained in the fourth part.

The relay program 19 in the additional information processing device 4 reads the accumulated record 15 from the accumulated file 3, assembles it as a message 22, and sends it to the existing calculation system 5. If a line failure 30 occurs on the line 17 during transmission or when receiving a transmission result, the communication control program 23 in the additional information processing device 4
detects the error and sends a failure notification 24 to the relay program 19. When the failure notification 24 is issued, it is unclear whether the processing on the existing computer system 5 side has been completed and the data file 6 has been updated. Therefore, the relay program 19 creates an inquiry message 28 inquiring about the processing result of the message 22 that encountered the failure, and sends it to the existing computer system 5. The inquiry message 28 is the inquiry program 2 of the existing computer system 5.
9, the data file 6 is referred to for the customer information of the specified telephone number, and the result is notified to the relay program 19 as an inquiry result 27.

The relay program 19 determines whether the customer information 27 in the inquiry result matches the customer information sent last time.

If they match, it is determined that the update has been completed and that the line failure occurred while receiving the transmission result, and the relay program 19 performs the process of reading the next accumulated file 3. If they do not match, it is determined that a line failure has occurred during transmission from the additional information processing device 4 to the existing computer system 5, and that the data file 6 has not been updated on the existing computer system 5, and a line failure has occurred. The same message as message 22 was sent to the existing computer system 5.
Send to. By realizing this retry process, the terminal 1
Processes that were previously performed manually by the person operating 2 can be automatically performed, improving operability.

Next, an embodiment of the message regulation process will be described with reference to FIG. 5, and a process flow of the relay program in the message regulation process will be explained with reference to FIG. 6.

If transaction processing for the same identification code, for example, the same telephone number, is performed multiple times from the terminal 1, there is a possibility that a plurality of storage records 15 having the same telephone number will exist in the storage file 3.

In this state, the relay program 19 reads the first 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. During processing in the existing computer system 5, if the telephone number in the message sent from the additional information processing device 4 is not in the data file 6, the existing computer system 5 notifies the relay program 19 of this as a failure notification. Notice. Note that whether a fault notification caused by a line fault is a fault notification caused by business program processing in an existing computer system is determined based on the fault information in the fault 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.Then, when the next storage record 15-2 in the storage file 3 is read, the relay program 19 registers the telephone number in the failure notification as the restriction information 34. The program 19 determines whether the telephone number in the storage record 15-2 matches the telephone number in the regulation information 34. If it matches, the stored record 1
The message transmission process for 5-2 is suppressed, and if there is no match, the message is created and transmitted. With this method, the failure notification from the existing computer system 5 can be made only for the first record of the stored records having the same identification code.

〔Effect of the invention〕

According to the present invention, it is possible to add and change functions to a business program of a large-scale system without modifying the existing business program, thereby reducing the number of man-hours required for adding and changing functions and improving serviceability for terminals. can be improved.

Furthermore, the retry process for failure notifications can reduce the intervention of the terminal operator, thereby automating the operation.

Furthermore, the message regulation process excludes messages with a high probability of error from being scheduled for transmission, which has the effect of suppressing the generation of wasteful transmission messages.
