要求元のプログラムからのデータ転送要求を受け取る。2. Description of the Related Art FIG. 2 shows a configuration example of a data transfer processing device, in which a data transfer section 2 includes a transfer request reception section 3, a transfer processing section 4, and a transfer result notification section 5. receives a data transfer request from the requesting program.

れたか否かを識別する。[0003] The data transfer request is made up of designation information such as the requester's name, destination name, data type, file name of the transmitted data, etc., and the transfer request accepting section 3 passes this to the transfer processing section 4. The transfer processing unit 4 determines a data transfer line 6 connected to the destination specified in the data transfer request, reads data from the specified file, transmits it according to a predetermined known transfer procedure, and receives the data from the destination device. It is determined whether reception has been performed normally by receiving a response indicating the status or by not receiving a predetermined response within a scheduled time due to a line abnormality or the like.

を応答して、データ転送要求の処理を完了する。[0004] When the data is successfully received, the transfer result notifying unit 5 responds to the request source that the data transmission has been successfully completed, thereby completing the processing of the data transfer request. In addition, in the case of an abnormality, retransmission is continued if necessary, and if reception still cannot be performed normally, the transfer result notifying unit 5 responds to the requester with an abnormal end, and the processing of the data transfer request is completed.

If an abnormal termination response is received, take appropriate response processing.
The configuration must be configured so that if necessary, the data transfer request is issued again.

る。[Problem to be Solved by the Invention] As described above, failure to complete transmission normally may also occur due to a relatively short-term abnormality in the line. In many cases, the error has been recovered, but even in such a case, the request is terminated abnormally, and the request source has to repeat the process of issuing a re-request, which delays data transfer and wastes computer resources. This results in the consumption of

If the numerical value is exceeded, the data transfer request is not stored in the retention request storage section 13, and a predetermined response indicating failure of the data transfer is returned to the request source.

減少できる。[Operation] When the data transfer processing device of the present invention fails, the request is saved and automatically retried after a certain period of time, during which time the data transfer requester is not involved at all. Since this is not necessary, it is only necessary for the request source to reissue a data transfer request in the case of a long-term line failure, and wasteful consumption of computer processing capacity can be reduced.

る。When the retention processing unit 11 receives a data transfer request from the transfer processing unit 15, according to the present invention, it checks the value of a trial count counter provided in addition to the request information, and if it has not reached a predetermined value, it determines the number of trials. Increase the value of the counter by 1 and store it in the retention request storage unit 13 together with the data transfer request,
The value of the term for the data transfer line 6 used by the line switch 17 is set to OFF, and the retransmission processing unit 12 is notified. Note that the initial value of the trial number counter is set to 0.

This is an example of the processing flow. When the retention processing unit 11 receives the data transfer request and the number of attempts counter from the transfer processing unit 15, it identifies the value of the number of attempts counter in processing step 20 of FIG. In processing step 21, the data transfer request is passed to the transfer result notification section 16 as an abnormal termination, and the processing ends.
