Abstract

PURPOSE:To decrease the cases where a terminal operator is kept waiting at the front of terminals owing to the deterioration of the terminal response by giving the information to the transmitter of the transaction data to interrupt the transmission of this data when the queue length of the data waiting for the transaction processing exceeds the largest queue length set previously. CONSTITUTION:A detecting part 361 of a queue length detection means 36 reads a queue length storing file 35, and an informing part 362 of the means 36 informs a transaction inflow controller 2 of the queue length. This queue length is compared with the largest queue length. If the former length is larger than the latter one, a discriminating part 25 discriminates that the start of the transaction processing is delayed. Meanwhile a message transmission part 27 sends the information to a terminal computer 1 to show that the transaction data were not received. When this information is received by a reception part 12 of the computer 1, an output means 13 outputs the contents of the information to an output device 14.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transaction inflow management device in a computer system constituting an online transaction processing system.

[0002]

2. Description of the Related Art Conventionally, in a computer system constituting an online system, after receiving transaction data, the transaction data is unconditionally registered in a queue waiting for transaction processing execution.

[0003]

In the above-described conventional transaction processing system, when transaction data more than the number of transactions that the computer system can process per unit time flows into the computer system, it is registered in the transaction processing queue. There is a problem that the number of transaction data to be processed remains in the queue, and as a result, the time from the reception of transaction data to the start of transaction processing execution is extended. Further, this causes a drawback that the terminal operator has to wait for a long time in front of the terminal from the transmission of the transaction data by keystroke of the terminal to the output of the result.

[0004]

In a transaction inflow management system of the present invention, in an online transaction processing system, transaction data receiving means, transfer means for transferring the transaction data received by the receiving means to a transaction processing computer, Detecting means for detecting the transaction processing queue length of the transaction processing computer, determining means for comparing a preset maximum queue length with the queue length, and the transaction processing computer based on the determination of the determining means. And a transmission means for transmitting a message indicating the busy status to the transmission source of the transaction data.

Further, in the transaction inflow management device of the present invention, when the queue length of transaction processing waiting data exceeds a preset maximum queue length, the transmission of the transaction data to the sender of the transaction data is interrupted. It is configured to let.

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

FIG. 1 is an explanatory view showing an embodiment of the present invention.

The terminal computer 1 has a transmitter 11, a receiver 12, an output means 13, and an output device 14.

The transaction inflow management device 2 has a reception unit 21, a detection unit 22, a queue length storage file 23, a maximum queue length storage file 24, a determination unit 25, a transaction data transfer unit 26, and a message transmission unit 27. There is. The queue length storage file 23 stores a queue identification name, and stores a queue length 231 of a queue having the same queue identification name. Further, the maximum queue length storage file 24 stores in advance the maximum queue length 241 corresponding to the queue identification name.

The transaction processing computer 3 includes a reception unit 31, a queue registration unit 32, a transaction processing queue 33 among a plurality of transaction processing queues, a queue extraction unit 34, a queue length storage file 35, and a queue. It has a length detecting means 36 and one transaction processing program 37 among a plurality of transaction processing programs. The queue length storage file 35 stores a queue identification name and a queue length 351. The queue length detection means 36 includes a detection unit 361 and a notification unit 362.

When the transmitting means 11 of the terminal computer 1 transmits the transaction data and the receiving means 21 of the transaction processing computer 2 receives the transaction data, the judging section 25 determines the queue length storage file 23 and the maximum queue length storage file. Read 24,
The queue length of the queue length storage file 23 and the maximum queue length of the maximum queue length file 24 are compared.

When the queue length is equal to or less than the maximum queue length, the transaction data is transferred to the transaction data transfer unit 26, and the transaction data is transferred to the transaction processing computer 3.

When the receiving unit 31 of the transaction processing computer 3 receives the transaction data, the queue registration unit 32 registers the transaction data in the transaction processing queue 33 and, at the same time, stores the transaction in the queue length 351 of the queue length storage file 35. The value for one data is added.

The queue retrieval unit 34 retrieves the transaction data from the transaction processing queue 33 and, at the same time, subtracts the value of one transaction data from the queue length 351 of the queue length storage file 35 to obtain a transaction processing program. Pass transaction data to 37.

The detection unit 361 of the queue length detection means 36 reads the queue length storage file 35, and the notification unit 362.
Notifies the transaction inflow management device 2 of the queue length.

In the above comparison of the queue length and the maximum queue length, if the queue length is larger than the maximum queue length, the determination unit 25 determines that the start of transaction processing is delayed, and the message transmission unit 27. Sends a notification to the terminal computer 1 that transaction data has not been accepted (in this case, "please wait for a while").

When the receiving section 12 of the terminal computer 1 receives the notification, the output means 13 outputs the content of the notification (“please wait for a while”) to the output device 14.

[0018]

As described above, according to the present invention, in the case where the start of transaction processing is delayed due to the retention of the processing queue of the host computer which constitutes the online system, the situation is immediately reported. By notifying the input terminal, there is an effect that it is possible to reduce the terminal operator from continuing to stand by in front of the terminal due to deterioration of the terminal response. This also reduces the mental stress on the terminal operator,
Also, there is an effect of improving work efficiency by reducing the waiting time in front of the terminal.
