Abstract

PURPOSE:To change a processing logic part of a program in an appropriate timing without stopping the device by making the processing logic part of the program, a data part, and a data reference defining part independent of each other. CONSTITUTION:A processing logic part of a program, a data part, and a defining part of a data reference are independent, respectively, and they are stored in means 10, 12 and 14, respectively. In such a state, the replacement of the program is executed by changing only the processing logic part. Also, a timing which can stop a program processing is detected, and by its timing, the processing logic part is changed automatically. In such a way, by changing the processing logic part by an appropriate timing, the program is improved.

[Industrial Application Field] The present invention relates to a device that executes a program to perform business processing.

The programs of computer systems used in banking and the like are often improved.

[Prior Art] When improving a program, the operation of the system is stopped.

The old program is then replaced with the new one, and then the system is started up and its operation resumed.

[Problem to be solved by the invention] As mentioned above, in the past, system operation was stopped in order to replace the block blank with a new one and improve it. cause interruptions.

This is particularly problematic in banking operations, which require continuous operations.

The present invention has been made in view of the above-mentioned conventional circumstances, and
The purpose is to provide a device that allows programs to be replaced without interrupting business operations.

[Means for Solving the Problems] In order to achieve the above object, the device according to the present invention has the following features:
It is configured as shown in the figure.

In the figure, the processing logic of the program is stored in means 10, the data referenced by the processing logic is stored in means 12, and the definition contents of data references are stored in means 14.

Then, the means 16 detects the timing at which the program processing can be stopped, and when the timing is detected, the program processing is controlled to be stopped by the means 18.

When this program processing stop control is performed, the previous processing logic is replaced by another processing logic by the means 20, and when the processing logic is replaced, the program processing is restarted by the means 22.

[Operation] In the present invention, the processing logic part, the data part, and the data reference definition part of the program are each independent, and are stored in the means 10, 12.14, respectively.

Program replacement is performed by replacing only the processing logic part.

Additionally, the timing at which program processing can be stopped is detected, and the processing logic portion is automatically replaced at that timing.

In other words, the program can be improved by replacing the processing logic part at an appropriate timing.

[Embodiments] Hereinafter, preferred embodiments of the apparatus according to the present invention will be described based on the drawings.

In FIG. 2, a display device 261 and a keyboard 28 are connected to the processing device main body 24, and a banking program is running on the processing device main body 24.

When it becomes necessary to improve a program running in the processing device main body 24, only the processing logic section of the program is transferred from the data storage device (another system) 30 to the processing device main body 24 via the line 32. be transferred.

In FIG. 3, the address space of the processing device main body 24 is explained, and in that space there is a first processing logic area 34. Second processing logic area 36. Data reference definition area 38.
A data area 4o is provided.

Among them, the first processing logic area 34 stores the processing logic part of the program used for actual processing, and the second processing logic area 36 stores the new improved processing logic part. Line 3 from storage device 30
Transferred via 2.

Further, the data area 40 stores data referenced by the processing logic section of the first processing logic area 34, and data indicating the definition content of the data reference is stored in the data reference definition area 38 (the (See Figure 4).

FIG. 5 explains the program exchange function of the processing device main body 24, and the input of a program exchange request (active patch processing request) is constantly monitored (step 500).
.

When the request is provided from input device 28 (or from an external system via line 32), step 50
0 (YES), the data storage device 30 upon acceptance of this request.
A new processing logic unit is transferred from the memory and stored in the second processing logic area 36 of FIG.

Furthermore, the replacement timing judgment module (see FIGS. 4 and 5) built in the processing logic section of the first processing logic area 34 is
(see figure) is activated, and this replacement time determination module determines whether or not it is time to stop the current program processing (processing logic) (step 502).

Then, when it is confirmed that it is time to stop the current program processing (YES in step 504),
), the program processing is controlled to stop as shown in FIG. 6 (step 506), and the new processing logic section transferred to the second processing logic area 36 is written into the first processing logic area 34 (step 508).

Upon completion of this writing, the program processing is controlled to be resumed (step 510), and therefore, thereafter, the data in the data area 40 is referenced by a new processing logic section as shown in FIG.

Note that writing to the first processing logic area 34 is prohibited, and the prohibition is canceled only when the program is replaced.

As explained above, according to this embodiment, the processing device main body 2
Since the program can be replaced without stopping 4, it is possible to avoid interruptions in banking operations.

Furthermore, according to this embodiment, the program is automatically improved at an appropriate timing, so that there is no impact on banking operations.

[Effects of the Invention] As explained above, according to the present invention, the processing logic section, data section, and data reference definition section of a program can be made independent of each other, and the program can remain active without stopping the device.
Since the processing logic part of the program can be replaced at an appropriate time, there will be no interruption of business operations using the device, and there will be no impact on business operations.
It becomes possible to automatically improve programs.
