Abstract

PURPOSE:To effectively use a transaction processing task by dynamically determining the execution priority of the task at the time of allocating task depending on whether the task is for the on-line transaction or the center-cut transaction. CONSTITUTION:When the idle task exists, a transaction processing control part 8 first preferentially allocates the on-line transaction to the task. After the allocation, it is transferred to a task execution priority determining part 9, the task execution priority fetermining part 9 sets the high priority at the task at the time of the on-line transaction, and sets the low priority at the task at the time of the center-cut transaction. For the transaction inputted in such a way, since the allocation control of the transaction processing task and the task executing priority are dynamically determined by the idle condition of the task and the queuing condition of the transaction, the transaction processing task can be effectively used.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transaction processing control system, and in particular, to a method for performing center-cut transaction processing while executing online transaction processing, such as in the center-cut processing format in banking systems. Concerning transaction processing control methods in executable systems.

[Conventional technology]

Conventionally, there have been two main methods for this type of transaction processing control. One method is to share multiple transaction processing tasks 12 between center-cut transactions and online transactions, as shown in FIG. 3, and the other method is to share execution priority tasks as shown in FIG. This system has an online transaction processing task 14 dedicated to high online transactions and a center cut transaction processing task 15 dedicated to center cut transactions with low execution priority. In each method, transactions are assigned to free tasks and processed in the order they arrive.

[Problem to be solved by the invention]

In the conventional transaction processing control method described above, the first method is when both online and center-cut transactions share the processing task, so both transactions have the same priority, and there are many center-cut transactions. has the disadvantage that online transaction priority is relatively lowered.

Furthermore, the second method fixes a dedicated task for each transaction, which has the disadvantage that tasks cannot be used effectively depending on the amount of online and center-cut transactions.

As a result, for example, when a center-cut transaction is submitted, the task assignment and execution priority of the online transaction are the same as those of the center-cut transaction in the first method, so the response of the online transaction decreases, and the second method With this method, even if online transaction tasks are available, they cannot be used.

In view of the above-mentioned points, an object of the present invention is to provide transaction processing control that allows online transactions to be processed preferentially regardless of the load status of online transactions and center-cut transactions, and that enables effective use of transaction processing tasks. The purpose is to provide a method.

[Means to solve the problem]

The transaction processing control system of the present invention includes a plurality of terminals and a center device, and the center device processes online transactions input from the terminals, and a center input input according to instructions from an operator of the center device. In a transaction processing control method in a system that simultaneously processes transactions, there is provided a transaction queuing unit that connects each online transaction or center cut transaction to a dedicated queue with a priority when the online transaction or center cut transaction is submitted; a transaction processing control unit that examines each of the dedicated queues according to the priority and allocates a task to the first transaction; The present invention is characterized by comprising a task execution priority determination unit that dynamically determines the priority.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

This transaction processing system includes a plurality of terminals 1,
A magnetic disk device 2 storing center-cut data, a transaction queuing section 3 including an online transaction queuing section 4 and a center-cut queuing section 5 that queue terminal transactions in a queue, and an online transaction queue. 6, a center cut queue 7, a transaction processing control unit 8, a task execution priority determination unit,
It is composed of a plurality of transaction processing tasks 10.

The transaction queuing section 3, which operates when a transaction is input, and the transaction processing control section 8 and task execution priority determining section 9, which operate when there is a vacant task, operate asynchronously.

When online transactions or center cut transactions are input, the transaction queuing unit 3 queues them in dedicated queues 6.7.

FIG. 2 shows the operations of the transaction processing control section 8 and the task execution priority determination section 9. If the task is available,
The transaction processing control unit 8 assigns tasks with top priority given to online transactions. After the allocation, the task execution priority determination unit 9 sets a high priority in the case of an online transaction and a low priority in the case of a center cut transaction.

〔Effect of the invention〕

As explained above, the present invention employs a system in which the allocation control of transaction processing tasks and the task execution priority for submitted transactions are dynamically determined based on the idle state of the task and the waiting state of the transaction, so that online transactions Even if center-cut transactions are submitted at the same time, online transaction processing is given top priority, and multiple transactions are set in the system depending on the input status of each transaction. Similarly, even in that case, there is an effect that the online processing can be given top priority.
