BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer management system for managing a timer request from a business program.

[0002]

2. Description of the Related Art Conventionally, a business program issues a time designation timer request and an interval timer request to a computer system, and when a time designated by the time designation timer request or a time designated by the interval timer request is reached. When the time has elapsed, a timeout message is transmitted from the computer system to the external system.

FIG. 4 is a block diagram for explaining this kind of prior art, which includes a computer 41, business programs 42-1 to 42-n, and external systems 43-1 to 43-43.
-M.

When the business program 42-i (1 ≦ i ≦ n) wants to transmit a timeout message to the external system 43-j (1 ≦ j ≦ m) at time T1, information indicating the business program 42-i of the transmission source , Destination external system 43-j
, The operation content for the external system 43-j,
A time designation timer request including the information indicating the time T1 and the serial number is sent to the computer system 41, and the time designation timer request is provided as timer request information to a timer request information management unit provided in the business program 42-i. Storing and then computer system 41
Wait for a response from.

The external system 43-j sends the current time T to the external system 43-j.
When a time-out message is to be transmitted after time T3 from time 2, information indicating the business program 42-i of the transmission source, information indicating the external system 43-j of the transmission destination, and the external system 4
3-j operation contents, current time T2, time T3
And an interval timer request including the serial number and the serial number are output to the computer system 41, and the interval timer request is stored as timer request information in the timer request information management unit provided in the business program 42-i. Wait for a response from the system 41.

When a timer request (time designation timer request, interval timer request) is added from the business program 42-i, the computer system 41 first determines whether or not the timer request can be accepted. That is, since the number of timer requests that can be processed simultaneously by the computer system 41 is predetermined, if the number of timer requests currently being processed has reached its upper limit, it is determined that the timer request cannot be accepted, If it is less than the upper limit, it is determined that it can be accepted.

If it is determined that the timer request cannot be accepted, the computer system 41 notifies the requesting business program 42-i that the timer request cannot be accepted by returning a negative response. Upon receiving the negative response, the business program 42-i issues a timer request to the computer system 41 again.

If it is determined that the timer request can be accepted, the computer system 41 returns an acknowledgment to the requesting business program 42-i, thereby notifying that the timer request has been accepted. Start processing for.

When the requesting business program 42-i returns an affirmative response, it resumes the processing interrupted for the response.

Further, the computer system 41 which has started the processing for the timer request receives the time T1 specified by the time specification timer request or the time T3 from the time T2 included in the interval timer request.
Of the external system 43-
A timeout message including the operation content is transmitted to j, and a timeout message including a serial number added to the processed time designation timer request and interval timer request is transmitted to the business program 42-i of the transmission source.

The external system 43-j receives the timeout message from the computer system 41, and performs a process according to the operation content contained therein.

In response to the time-out message returned from the computer system 41, the business program 42-i as the request source receives a time-out message from the timer request information in the timer request information management unit and has a serial number included in the time-out message. A flag indicating that processing has been completed is added to the request information. That is, a flag indicating that processing has been completed is added to the timer request information corresponding to the processed timer request, so that an unprocessed timer request can be confirmed by referring to the contents of the timer request information management unit. This can be used for failure analysis, operation confirmation, and the like.

[0013]

As described above, conventionally, the number of timer requests that can be accepted by a computer system is determined in advance, and if a timer request is not accepted, the business program issues a timer request again. Since it had to be output, there was a problem that the processing of the business program was hindered by the timer request.

It is an object of the present invention to provide a timer management system in which the processing of a business program is not hindered by a timer request.

A timer that outputs the next interval timer request that is connected to the queue when an interval timer request is accepted, and outputs again the interval timer request that is connected to the head of the queue when it is not accepted. And determining whether or not the interval timer request output from the timer management unit can be accepted, and accepting the interval timer request from the timer management unit by determining that the interval timer request can be accepted. A computer system for sending a timeout message to an external system when the time indicated by the interval timer request has elapsed from the time at which the timer request was output.

[0017]

In the configuration (A), when a time designation timer request is output from the business program, the timer management unit stores it in the timer management database and queues it. When a time designation timer request is connected to the queue, the timer management unit outputs the time designation timer request connected to the head of the request to the computer system.
If the time-specified timer request output to the computer system is accepted, the next time-specified timer request that is enqueued is output to the computer system, and if not, it is enqueued at the head of the queue. The time designation timer request is output to the computer system again.

When a time designation timer request is added from the timer management unit, the computer system determines whether the request can be accepted. When it is determined that the request can be accepted, a time designation timer request from the timer management unit is accepted, and a time-out message is sent to the external system when the time indicated by the accepted time designation timer request comes, and the process is sent to the timer management unit. Sends a timeout notification indicating the completed timer request.

When the timeout notification is sent, the timer management unit adds information indicating that the processing has been completed to the time specification timer request indicated by the timeout notification among the time specification timer requests stored in the timer management database.

In the configuration (B), when an interval timer request is output from the business program, the timer management unit stores the interval timer request in the timer management database and queues it.

The interval timer request stored in the timer management database is added with information indicating that processing has been completed by the timer management unit when the time indicated by the request has elapsed.

The interval timer request connected to the head of the queue is sent to the computer system by the timer management unit. If the request is not received by the computer system, the request is transmitted again. If the request is received, the next interval timer request in the queue is transmitted to the computer system.

When an interval timer request is added from the timer management unit, the computer system determines whether the request can be accepted. Then, by determining that the interval timer request can be accepted, an interval timer request from the timer management unit is accepted, and a timeout message is sent to the external system when the time indicated by the interval timer request has elapsed since the business program output the interval timer request. .
