[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-line terminal input simulation apparatus, and more particularly to an on-line terminal input simulation apparatus which facilitates performance evaluation and failure analysis when an online system is constructed.

[0002]

2. Description of the Related Art Conventionally, a central processing unit and a plurality of online terminal units are connected via a communication line, a processing request from each online terminal unit is sent to the central processing unit, and the requested processing is executed in the central processing unit. There is an online system in which the execution result is returned to the requesting online terminal device. By performing performance evaluation and failure analysis when constructing this online system, the system's performance is measured in advance and failures are prevented. Performance evaluation and failure analysis at the time of system construction are carried out by performing a simulation based on simulation data in a dedicated format prepared on the online terminal side.

FIG. 6 is a diagram showing a schematic configuration of a conventional online system. In this figure, only one online terminal device is shown.

Central processing unit 1 and online terminal unit 2
Are connected via the communication line 3. A communication module 4 dedicated to the simulation is mounted on the central processing unit 1 during the simulation. On the other hand, the online terminal device 2 is equipped with a communication module 5 dedicated to the simulation and a simulation module 6 for executing the simulation during the simulation. The online terminal device equipped with the communication module 5 and the simulation module 6 at the time of executing the simulation will be referred to as a terminal control device 2. Further, the terminal control device 2 is connected to an input device 7 such as a keyboard for inputting data to be transmitted to the central processing unit 1 and a file device 8 for storing simulation data in advance. A conventional online terminal input simulation device is composed of the above elements.

Conventionally, in order to perform a simulation of an online system, it is necessary to first input data from the input device 7 of the terminal control device 2. This is a procedure of the simulation data already prepared in the file device 8. The input data such as the input character string is transmitted to the central processing unit 1 at regular intervals. Then, the failure is analyzed by checking whether data transmission / reception is normally performed, and the system capability is evaluated by measuring the time required for data transmission / reception.

[0006]

However, since the simulation is conventionally performed as described above, there are the following problems.

First, in order to perform a simulation in an online system, both the central processing unit side and the terminal control unit side require communication modules dedicated to the simulation.

Further, it is necessary to prepare in advance dedicated simulation data for performing the simulation. For this reason, it was not possible to perform a simulation in accordance with the environment, such as being able to perform a simulation only at a predetermined time interval.

As described above, it is difficult to say that the simulation can always be easily performed because many structures used only for performing the simulation are required.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an online terminal input simulation apparatus capable of easily executing various simulations.

[0011]

In order to achieve the above-mentioned object, the present invention relates to a plurality of online terminal devices which are connected to a central processing unit via a communication line and each have an input device. In an online terminal input simulation device that performs an input simulation, transmission and reception between an emulator that emulates each of the online terminal devices as a terminal of the central processing unit and information associated with an input operation from the input device and the central processing unit It is characterized by having a data collecting means for collecting information and a storage means for storing the data collected by the data collecting means.

Further, the present invention is characterized by further comprising input operation simulation means for performing a simulation based on information associated with an input operation from the input device stored in the storage means.

Further, it is characterized in that it has a central processing unit synchronization means for monitoring interruption of transmission / reception of the emulator, and the input operation simulation means carries out a simulation at a timing instructed by the central processing unit synchronization means.

The input operation simulation means operates in parallel with the data collection means.

The present invention is characterized by further comprising fault information collecting means for collecting fault information obtained by comparing the data transmitted and received by the simulation with the data stored in the storage means.

[0016]

In the online terminal input simulation apparatus according to the present invention having the above structure, the data collecting means collects the input operation from the input device and stores it in the storing means. By using the stored input operation as the actual data of the simulation, the simulation can be performed at a desired timing without preparing the simulation data in advance.

Further, the input operation simulation means is
The simulation is performed based on the input operation stored in the storage means. When the central processing unit synchronization means receives a response from the central processing unit, the central processing unit synchronization unit notifies the input operation simulation unit of the synchronization timing, so that the input operation simulation unit can perform the simulation at the timing led by the central processing unit. .

The data collecting means and the input operation simulation means can also operate in parallel.

Further, since the failure information collecting means compares the input operation stored in advance at the time of data transmission / reception with the central processing unit at the time of simulation execution with the actual transmission / reception data, it is detected that a failure has occurred. Then, the failure information can be collected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. The same elements as those in the conventional example are designated by the same reference numerals.

Example 1. FIG. 1 is a diagram showing a schematic configuration of an online system using an online terminal input simulation device according to the present invention. 1 as in the conventional example
Only one online terminal is shown. The terminal control device 12 according to the present embodiment includes a general-purpose emulator 14 that emulates each terminal control device 12 as a terminal of the central processing unit 11, and information and central processing unit 11 associated with an input operation from the input device 7. An actual data collection module 16 as a data collection means for collecting transmission / reception information between the two via the emulator 14. In particular,
Input data sent from the input device 7 to the emulator 14,
For example, when the input device 7 is a keyboard, the contents of keyboard operation and the time or time interval of the operation are collected as information associated with the input operation. In addition, a message received by the emulator 14 from the central processing unit 11 or the central processing unit 11
The input data from the keyboard to be transmitted to and the time or time interval of transmission / reception are collected as transmission / reception information. In order to collect data, the emulator 14 and the input device 7 are set with interrupt addresses in advance in the actual data collection module 16.
Make a change. The file device 8 in this embodiment is used as a storage means for storing these data collected by the actual data collection module 16. Further, the terminal control device 12 has a simulation module 18 as an input operation simulation means for performing a simulation based on an input operation from the input device 7 stored in the file device 8 and a central processing for monitoring an interrupt of transmission / reception of the emulator 14. And a central processing unit synchronization module 20 as a device synchronization means. In the central processing unit synchronization module 20, the interrupt address of the emulator 14 is set / changed in advance in order to monitor the interrupt.

The feature of this embodiment is that the input from the keyboard and the time are collected, so that the information associated with this input operation can be used without preparing the simulation data in advance. The simulation can be performed, and the simulation can be performed at a desired timing.

FIG. 2 is a flow chart showing the processing of the actual data collection module 16 in this embodiment. The operation of collecting information in this embodiment will be described below with reference to this figure. The case where the input device 7 is a keyboard will be described.

When an interrupt is generated from the emulator 14 or the keyboard (step 101), the process of the actual data collection module 16 is started to collect the transmission / reception information or the input operation (steps 102 to 105). The process after collecting the information and storing it in the file device 8 is performed by the original process of the emulator 14 and the keyboard and is repeated until the end command is received (step 10).
6). As described above, since the actual data collection module 16 is provided so that the transmission / reception information or the input operation can be collected without affecting the normal processing, it is not necessary to provide the simulation data in advance.

FIG. 3 is a flow chart showing the processing of the simulation module 18 in this embodiment, and FIG. 4 is a flow chart showing the processing of the central processing unit synchronization module 20, respectively. Next, the processing for performing a simulation based on the input operation of the collected keyboard. Will be described.

The simulation module 18 performs a simulation based on the keyboard input operation stored in the file device 8, and the first input operation is transmitted from the terminal control device 12 to the central device 11 via the emulator 14 ( Step 201). When data is transmitted / received, an interrupt occurs in the emulator 14, so that the processing of the central processing unit synchronization module 20 starts. As a result, the central processing unit synchronization module 20 constantly monitors the data transmission / reception performed via the emulator 14 and collects the transmission / reception information, but when the collected information is a response from the central processing unit 11 (step 301, 3
02), and notifies the simulation module 18 of the synchronization timing (step 303). The central processing unit synchronization module 20 ends the process when it receives the end command via the emulator 14 (step 304).

The simulation module 18 confirms the contents of the response from the central processing unit 11 and freely sets the time interval stored in the file device 8 or an integral multiple or an equal interval thereof, and the setting is made. The next input operation is transmitted at a predetermined time interval (step 2).
03). This is repeated until the end command is received (step 204). In this way, the central processing unit 1
It is possible to perform a simulation in consideration of the load applied to 1. Further, since the next input operation is transmitted after detecting the response from the central processing unit 11, it is possible to perform the simulation led by the central processing unit in consideration of the processing capacity of the central processing unit 11. That is, if the next input operation is immediately transmitted in response to the response of the central processing unit, the simulation can be performed with the maximum load applied to the central processing unit. Since the transmission / reception information is stored in the file device 8, the maximum performance of the central processing unit 11 in the online system can be obtained by referring to the contents.

Further, in the present embodiment, the central processing unit 11 does not need a dedicated communication module or the like for performing a simulation, and only the terminal control unit 12 needs the above-mentioned elements. Furthermore, the simulation in this embodiment can be executed without changing the environment of the software in operation, and can be performed by using the general-purpose emulator 14, the input device 7, and the file device 8 that are normally used. You can

Example 2. In the first embodiment, the input operation from the keyboard is collected as actual data, and then the simulation is performed using the collected actual data. However, the actual data collection module 16 is activated during the simulation by the simulation module 18. Then, the simulation module 18 and the actual data collection module 16 may be operated in parallel. As a result, actual data can be collected while performing the simulation.

When the simulation is executed by the simulation module 18, the keyboard may be operated to input the actual data to be transmitted to the central processing unit 11.

Example 3. In each of the above examples, the performance of the central processing unit 11 could be evaluated by the above configuration. In the present embodiment, in addition to the above configuration, the terminal control device 12 is further provided with failure information collecting means for collecting failure information obtained by comparing the data transmitted / received by simulation with the data stored in the file device 8. The failure information collecting module 22 is provided. The failure information collection module 22 sets / changes the interrupt address of the emulator 14 in advance in order to refer to the data transmitted / received to / from the central processing unit 11.

FIG. 5 is a flow chart showing the processing of the fault information collection module 22 in this embodiment, and the operation of this embodiment will be described below with reference to this figure.

When data is transmitted / received to / from the central processing unit 11, an interrupt occurs in the emulator 14, so that the processing of the fault information collection module 22 starts (step 401). As a result, the failure information collection module 22
Always refers to the contents of data transmission / reception performed via the emulator 14, and compares the transmitted / received data with the actual data prepared for transmission / reception (step 402). As the actual data, the data collected by the input operation of the keyboard and stored in the file device 8 in advance is used. If these data are compared (step 403) and the contents of the data are different or the transmission / reception timings are different, it is determined that some kind of failure has occurred, and the time of the event, the content of the comparison, etc. It is collected as information and recorded in the file device 8 (step 404).
In this way, the failure information can be collected when executing the simulation. This process is repeated until the end command is received (step 405).

In each of the above-mentioned embodiments, the online terminal input simulation device mounted on the online terminal device has been described. However, the online terminal input simulation device of this embodiment is used for response measurement and operation recording of the online terminal device. Can also be applied.

[0035]

According to the first aspect of the present invention, the data collecting means is provided so that the transmission / reception information or the input operation can be collected without affecting the normal online processing. There is no need to provide data. The actual data used to perform the simulation can be easily obtained by a simple input operation from the input device, and the contents can be arbitrarily set according to the load status of the central processing unit. Therefore, it is possible to perform a desired simulation according to the environment of the online system.

Further, since the central processing unit does not require a dedicated communication module for performing the simulation, it is simple and more accurate performance evaluation can be obtained.

According to the second aspect of the invention, since the input operation simulation means is provided, the simulation can be performed based on the input operation stored in the storage means.

According to the third aspect of the present invention, the central processing unit synchronizing means is provided so that the response of the central processing unit can be detected. Therefore, a simulation led by the central processing unit is performed according to the response timing. It becomes possible. That is, if the next input operation is immediately transmitted in response to the response of the central processing unit, the simulation can be performed with the maximum load being applied to the central processing unit.

According to the invention described in claim 4, it is possible to collect the actual data while operating the input operation simulation means and the data collection means in parallel.

According to the fifth aspect of the invention, since the failure information collecting means is provided, it is possible to collect the failure information at the time of executing the simulation.
