JPH04256019A - Same processing re-execution preventing device - Google Patents

Abstract

PURPOSE:To save time and manhour by making it unnecessary to copy saved data before update, to generate a program for restoring the data, or to input the data again. CONSTITUTION:A same processing re-execution preventing device 10 is constituted of a processing starting device 1 for starting the processing of an information processing system, an execution history storage checking means 2 to decides whether the processing started by this was started before or not by referring to a processing execution history table 3, and a re-execution caution display means 4 to display an alarm on an output device 6, and simultaneously, input the selection of the propriety of the continuation of the processing when check results in decision that the processing was started before, and an execution history storage means 5 to store the history of the processing in the processing execution history table 3 after the end of the started processing.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing re-execution of the same process, which issues a warning to an operator if the activated process has already been executed when the process is activated in an information processing system.

0002

2. Description of the Related Art Currently, information processing systems are widely distributed, and the number of operators who operate the information processing systems is increasing. Large computer systems are often operated by operators with specialized knowledge, but medium and small computer systems, which make up the majority of information processing systems in circulation, do not have such specialized knowledge. It is often operated by an operator.

[0003] Therefore, in an information processing system operated by such an operator or an information processing system operated by multiple operators, the same process may be started more than once without realizing it. be. If this process is a data update process, data will be erased or destroyed.

In such cases, in conventional information processing systems, if the data before the update has been saved, the saved data is copied to restore the state before the update, or the data before the update is logically restored. The solution was to create a program that could restore the corrupted data, or to re-enter normal data on the screen to replace the corrupted data.

[0005]

[Problems to be Solved by the Invention] In the above-mentioned conventional information processing system, when the same process is started more than once and data is erased or destroyed, it is necessary to either copy the saved data before updating or restore the data. The disadvantage was that it required a large amount of time and man-hours, as it required either creating a program to restore the data or re-entering the data.

In view of the above points, an object of the present invention is to store the execution history of a process in an execution history storage table, refer to the execution history storage table when starting the process, and display a warning on the screen output device in the case of re-execution. An object of the present invention is to provide an apparatus for preventing the re-execution of the same process, which can prevent data erasure or data destruction due to re-execution of the same process by displaying this and allowing the operator to select whether or not to continue the process.

[0007]

[Means for Solving the Problems] The same processing re-execution prevention device of the present invention includes a processing starting device for starting a process of an information processing system, and a processing started by the processing starting device that has already been started. an execution history memory checking means for determining whether or not the processing execution history is present by referring to a processing execution history table;
If the result of the execution history memory check means is that it has already been activated, a warning is displayed on the output device, and a re-execution warning display means is provided for selecting whether or not to continue the process. and execution history storage checking means for storing the processing history in the execution history storage table when the processing is terminated incorrectly.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. 1, the same process re-execution prevention device 10 of the present embodiment includes a process starting device 1, an execution history storage check means 2, a re-execution warning display means 4, an execution history storage means 5, and an output device 6. The processing execution history table 3 is connected to the processing execution history table 3.

The process starting device 1 uses a keyboard as an input source and takes in the name of a process that an operator wants to start. Next, the execution history memory checking means 2 refers to the process execution history table 3 based on the process name input from the process starting device 1,
Determine whether the process has already been executed, and further,
If it has already been executed, determine whether it can be executed again. Subsequently, if the execution history memory checking means 2 determines that the process has been executed, the re-execution warning display means 4 displays a warning message on the drawing of the output device 6 to warn that the process is to be re-executed. Let's do it. Further, if re-execution is possible, the operator is asked to select whether or not to continue the process, and if the process is not to be continued, the process is terminated. Then, after the execution of the process is finished, the execution history storage means 5 stores the process execution history table 3.
The executed classification is set as executed.

[0011] This will be explained in more detail with reference to FIG.

FIG. 2 is a diagram showing the structure of the processing execution history table 3.

Based on the name of the process started by the process starting device 1, the process execution history table 3a is searched for the contents of the same process name. In the example of process name A in the process execution history table 3a, the executed category is "0" (process not executed).
Therefore, the re-execution warning display means 4 does not issue a warning,
The execution history storage means 5 stores that the process has been executed in the executed category.

Further, in the example of process name B, since the executed classification "1" is (process executed), the re-execution warning display means 4 displays a warning on the drawing of the output device 6 that re-execution is to be performed. display. Furthermore, the re-executable classification is “
0'' (a re-executable process), the operator is prompted to select whether or not to continue the process using the output device 6. If the operator selects to continue the process, the same process is re-executed,
Further, if the end is selected, the process ends without executing the process.

Finally, in the example of process name C, since the executed classification is "1" (process executed), similar to process name B, the re-execution warning display means 4 displays a message on the drawing of the output device 6. A warning message will be displayed to warn you that the process will be re-executed. However, since the re-executable classification is "1" (a process that cannot be re-executed), the process is not executed and ends.

[0016]

Effects of the Invention As explained above, the present invention displays a warning on the screen of the output device when the same process is re-executed. In an information processing system operated by multiple operators, there is no possibility of accidentally erasing or destroying data.

Therefore, there is no need to copy the saved data before updating, create a program to restore the data, or input the data again, as in the past, and the effect is that the time and man-hours required for this can be saved. be.
