JPS628250A - Generating system for high load transaction - Google Patents

Abstract

PURPOSE:To easily perform a high load test by returning the value of an input field without inputting a key-in by a display terminal against a telegram having a prescribed value of instant response display bit, and returning print completion without printing by a printer terminal. CONSTITUTION:After a menu picture plane is transmitted 101 from a center to a terminal, an operator at a terminal side selects 102 a job to be processed by the menu and starts up 103 the job. At the next, when the telegram having data instead of key-in input, setting an instant display bit as 1, from the center is transmitted 104, the terminal returns 105 the data from the center without waiting the key-in by the operator. After the job is carried out 106 against the response, with transmitting 107 on which printed data are present and the printed data setting the instant display bit as one, a terminal side returns immediately the print completion without performing a print operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high-load transaction generation method for performing online system evaluation under high load before starting a service.

[Conventional technology]

Conventionally, in order to verify the operating status of the system during peak hours before starting service of an online system, it is necessary to generate peak load using all the actually installed terminals, or to place the central computer in the opposite direction. The method used was to use one computer to generate and verify transaction data corresponding to peak times.

[Problem that the invention seeks to solve]

Among the conventional high-load transaction generation methods described above, in which all terminals are actually used to generate transactions, it is difficult to imagine that all terminals are installed before the online service starts, which is the time when evaluation is required. Not limited to
Also, since the terminals are scattered all over the country, there is a drawback that it is difficult to perform evaluations easily. Also, connect a computer to the opposite side,
The method of generating a high load requires hardware equipment such as an opposing computer and line, and has the drawback of requiring man-hours to develop software for a program tool for generating test data. be.

[Means for solving problems]

The system of the present invention includes an immediate reply display bit in the message used between the center computer and the terminal, and when the instant reply display bit receives a message with a predetermined value, K responds to the message in the case of a display terminal. When the terminal is a printer terminal, K responds to the message and returns print completion information without printing.

〔Example〕

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

FIG. 3 shows an example of conventional communication between a center and a terminal.

The data sent from the center to the display terminal includes display screen data and initial values for input fields on the screen, and when the terminal receives these data, the operator keys in the appropriate data for the input field on the screen. This keyed-in data is returned from the terminal to the center and processed at the center.

The time required for one transaction in such normal communication is the line transmission time T, the terminal data input time from receiving data at the terminal to keying in the corresponding data and transmitting this keyin data 11 If the processing time in the center is P, it is approximately (T+I+P) and n
The number N of online transactions generated per unit time from terminals is expressed by the following equation.

The suffix i means that it corresponds to the first terminal.

Among the above T, I, and P, the highest threshold value is l.

This is because the process usually includes the operator's thinking time for key-in. Therefore, in the present invention, by setting I=o, the number of occurrences of online transaction 1 is increased, and it is intended to be used for evaluation under high load.

FIG. 1 shows a flowchart of one embodiment of the present invention.

Further, FIG. 2 shows the message format used in this embodiment.

The message format shown in FIG. 2 includes an immediate reply indication bit F in addition to the normal protocol header.

B) When F is "1", if it is a display terminal, data key-in is not required and the data in the input field on the display screen is returned, and if it is a printer terminal, K indicates "1 printing is completed immediately without performing a print operation." When bit F is @0'', the terminal operates as usual.

The procedure of this embodiment will be explained with reference to FIG.

The center sends a menu screen (processing task selection screen) to multiple terminals with F=0 (step 101). The operator of terminal a inputs the processing task name on this screen (step 102). As a result, the data type of the transaction is not unique, and the data distribution can be made to be similar to that during the actual service. When a processing task is selected on the menu screen, a screen corresponding to the selected task is displayed on the terminal, and the screen display data includes screen data and initial value data for each input field. Here, in order to use the initial value data of the input field as a substitute for the input data of the terminal, the center sends significant data in advance, and bit F on the host-terminal protocol is sent as @1'' (step 104).As a result, the terminal substitutes the data sent by the center for the key-in data of the terminal,
The data is sent back to the center (step 105).

When printing data is sent to a terminal in a processing operation, it is sent as bit Ft-11# of the host-to-terminal protocol (step 108), so that printing is treated as completed without actually printing on multiple terminals (step 109). Become.

In this way, according to this embodiment, the number of transactions generated from one terminal can be increased by eliminating key-in time or printing time for multiple terminals. In this way, it is possible to perform an online high-load test by increasing the number of transactions occurring at each terminal.

〔Effect of the invention〕

The present invention includes data key-in time at the terminal.

By saving printing time, it is possible to increase the number of online transactions of terminals during testing.This has the effect that testing at peak times can be conducted efficiently before service starts with a small number of terminals. be.

Claims (1)

[Scope of Claims] An immediate reply display bit is provided in a message used between a center computer and a terminal, and when a message in which the immediate reply display bit has a predetermined value is received, the display terminal responds to the message. A high-load transaction generation method characterized in that display data is returned to an input field on a screen without a key-in, and when a printer terminal is used, print completion information is returned without printing in response to the message.
