Abstract

PURPOSE:To use a journal file in the batch serial processing to reproduce the online processing by writing events, which occur in time series, in the journal file as text data in case of the time series processing. CONSTITUTION:When an online processing module 12 receives a reception text 11 in the online distributed processing, a request text data 21 is transmitted to a remove online processing module 14, and terminal reception text data 51 is written in a journal file 5 and the control is transferred to a timer monitor submodule 13. If the submodule 13 returns the timer report to the module 12 when a response text 41 is not returned within a certain time, the cancel processing and timer report data 52 are outputted to the file 5 for the request text 21. In the batch serial processing, data 51 of the file 5 is read by a batch serial processing module 200 and is transferred to a batch online processing module 22, and the processing similar to the online distributed processing is performed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention reproduces online processing using a batch serial method from received message data of a journal file without inputting message data from a terminal or a remote computer system. Regarding online processing reproduction method.

[Conventional technology]

Conventionally, in this type of processing, the received message data of the journal file created during online processing was extracted, and this message data was transferred to the online processing program as if it had been received from each terminal (terminal). The executed process was to be reproduced using batch serial processing.

[Problem that the invention seeks to solve]

With the conventional function, due to the nature of batch serial processing, for example, when transmitting message data between computers in online processing, in the case of inquiry-based processing, the requested message data is processed by the other computer and returned as response message data. It is necessary to monitor the situation until the end. Normally, this function determines a certain period of time (interval) and monitors the time between this interval. If this is reproduced by batch serial processing, since the other computer is not installed, the response message data to the request message data will be returned immediately, resulting in a time difference from online processing. As described above, the conventional batch serial processing method has the disadvantage that time-series processing that takes into account the other computer cannot be reproduced.

An object of the present invention is to provide an online processing reproduction method that eliminates the above-mentioned drawbacks and allows even time-series online processing to be reproduced by batch serial processing.

[Means for solving problems]

The configuration of the online processing reproduction method of the present invention is such that, in the reproduction method of an online distributed processing system in which a received message input from a terminal device of a host computer is processed online and an inquiry is made to a remote computer system, the host computer It is equipped with an external file that stores online processing data as a journal file, including timer monitoring control for communication between systems, and during batch serial processing, online processing is reproduced by using the online processing data stored in the external file. It is characterized by

〔Example〕

Next, the present invention will be explained below based on the drawings.

FIGS. 1(a) and 1(b) are block diagrams showing one embodiment of the present invention. FIG. 1(a) is a block diagram when online distributed processing is being performed, and FIG. 1(b) is a block diagram showing an embodiment of the present invention. It is a block diagram when reproducing online processing by batch serial processing, and 1 indicates a host computer system and 2 indicates a remote computer system.

In this figure, we will first use Figure 1 (
When the online processing module 12 receives the received message 11 from the terminal 1 in the online distributed processing of a), it sends the request message data 21 to the remote online processing module 14 of the remote computer system 2 and at the same time writes the request message data 21 into the journal file 5. Terminal received message data 51 from the terminal device 10 is written to , control is transferred to the timer monitoring sub-module 13 that performs timer monitoring, and there is no response message 41 from the remote online processing module 14 within a fixed interval of, for example, 30 seconds. In this case, when the timer monitoring sub-module 13 returns a timer notification to the online processing module 12, the online processing module 12 outputs the cancellation process to the previous request message 21 and the timer notification data 52 to the journal file 5.

This online distributed processing is reproduced by batch serial processing, which performs pseudo online processing as shown in Figure 1(b).The journal file 5 output by the online distributed processing in Figure 1(a) is The batch serial processing module 200 first reads the terminal received message data 51 transmitted from the terminal 10, passes it to the batch online processing module 22, and performs the same processing as the online distributed processing shown in FIG. 1(a). However, since the remote computer system 2 is not installed due to batch serial processing (indicated by the broken line in the figure), no request message is issued, and no timer instruction is given to the timer monitoring submodule 13. Therefore, the batch serial processing module 200 subsequently reads the timer notification data 52 from the journal file 5, so that the batch online processing module 200 receives the timer notification from the timer monitoring submodule 24 of the remote online processing module 14. By transferring control to , it can be realized with Basochi serial processing, including timer monitoring processing.

〔Effect of the invention〕

As described above, the present invention writes events that occur in chronological order to a journal file as telegram data when performing time-series processing in online processing, and uses this journal file in batch serial processing to perform online processing. This has the effect of making it possible to reproduce and pseudo-online processing.
