Abstract

PURPOSE:To obtain the same output result that is obtained in the case of the end of report transfer without interruption by automatically removing overlapping pages to print a report at the time when several pages of the report are doubly transferred by the interruption of transfer due to the occurrence of trouble. CONSTITUTION:If trouble occurs in the middle of data reception, a reception control means 8 transmits the indication, which restarts transmission with several preceding pages, to a computer 1. When data is retransmitted, a file write means 9 reports a first report file name before the occurrence of trouble, the presence of a second following report, the second report name, etc., to an output queue register means 12, and this means 13 detects overlapping pages to register them in an output queue 11, and a printer output means 10 prints the first report file and starts printing of the second report file from the printing start page. Thus, the same printer output image that is obtained in the case of the end of report transfer without interruption is obtained, and the processing time is approximately equal to that in this case.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a report output control method, and particularly to a report output control method when a failure occurs during report transfer between computers and it becomes necessary to resend the report.

[Conventional technology]

In conventional report transfer, there is no problem if the transfer completes normally without any problems, but if some failure occurs during the transfer and the transfer is interrupted and resumed, how much of the report will be lost? Once the transfer has completed and been written to the receiving file, there is no way to know for sure where to start the transfer again.

Therefore, the first method is to restart the transfer from the beginning of the report, or to prepare for the possibility that there will be duplicate data received on the receiving side, go back several pages and resend it, and after printing the duplicated data to the printer. A second method is adopted in which the .

[Problem to be solved by the invention]

Of the conventional methods mentioned above, the first method may be acceptable when the amount of data is small, but when a large amount of data is transferred, it has a large impact on time, and the use of the same line becomes difficult. The economic burden associated with this is large and is not practical. On the other hand, in the second method, a person must perform a pressure test on the overlapped data and then discard the overlap.

An object of the present invention is to maintain the same printer output image even when a failure occurs and the transfer is interrupted and restarted during report transfer between computers, compared to when the report transfer ends without interruption. An object of the present invention is to provide a report output control method configured so that processing times are almost equal.

[Means to solve the problem]

The report output control method according to the present invention transfers a report in a sending file used by a first computer to a receiving file using a second computer connected to the first computer by a communication line, In a report output control method in which the report is output to a printer connected to the second computer via an output queue in the second computer, the first computer includes: a file reading means for reading a report to be transferred from the transmission file; a data transmitting means for transmitting the data read by the file reading means; and a data transmitting means for monitoring the transmission status and receiving a retransmission instruction from the second computer when a failure occurs and giving the file reading means to reread from several pages earlier. the second computer comprises: a data receiving means for receiving data from the first computer; and a file writing means for writing the data from the data receiving means into a report file; It monitors the reception status, instructs the first computer to resend data from several pages earlier when a failure occurs, and also notifies the file writing means that the transfer has been interrupted. is output to a separate report file, and several pages of both report files are output based on the report file before the failure occurrence and the report file after retransmission, according to instructions from the file writing means. an output queue registration means that detects duplicates in the report file after retransmission, determines from which page the report file should be printed to eliminate the duplicates, and registers both report files together with that information in the output queue; For registered report files, check whether there are any report files that should be printed continuously and the page to start printing them. If there is a continuation report, print the report file before the failure occurred first, and then print it again after resending. and printer output means for printing the report file from the printing start page.

〔Example〕

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

Referring to FIG. 1, which shows the configuration of an embodiment of the present invention, this embodiment includes data transmitting means 4. Transmission control means 5. A computer 1 consisting of a file reading means 3, a transmission file 6 related to the computer 1, and a data receiving means 7
．． Reception control means 8, file writing means 9. Printer output means 10, output queue 11. Output queue registration means 12
1, a receiving file 13 related to the computer 2, and a communication line 15 for connecting the computer 1 and the computer 2.

FIG. 2 is an example of the structure of an output queue.

In Figure 1, in order to avoid cluttering the drawing, computer 1 is depicted as performing only transmission, and computer 2 is depicted as performing only reception, but it is possible to perform both reception and transmission within one computer. They may be configured to face each other like this.

In FIG. 1, the transmission control means 5 instructs the file reading means 3 to read the report file transmitted by the transmission file 6. The file reading means 3 reads the report file sent by the sending file 6 and passes it to the data sending means 4. Data transmitting means 4 transmits data to computer 2. The data receiving means 7 receives data from the computer 1 and passes it to the file writing means 9.
writes the data to the receiving file 13.

When the data reception is completed normally, the file writing means 9 sends report file information such as the report file name and the fact that there is no continuation report to the output queue registration means 12.
Notify. In response to this, the output queue registration means 12
A report file is registered in the output queue 11. The printer output means 10 refers to the output queue 11 and outputs the report file to the printer 14.

If a failure occurs during data reception, after the failure is recovered, the reception control means 8 sends a retransmission instruction from several pages earlier to the computer 1. Further, for the file writing means 9,
Informs that there is data to be resent and instructs it to be output to a separate report file.

Upon receiving the instruction, the transmission control means 5 transmits the file reading means 3 to the file reading means 3.
command to reread a few pages earlier.

When the data is retransmitted, it is received by the data receiving means 7 and written to a report file by the file writing means 9. When the reception of the retransmitted data is completed, the file writing means 9 notifies the output queue registration means 12 of the name of the first report file before the failure occurred, the fact that there is a second report that was retransmitted, the second report name, etc. .

The output queue registration means 12 recognizes that there is a continuation second report in the first report file, detects duplicate pages between the first report file and the second report file, and stores the duplicate pages in the output queue 11. , the second report file entry contains the name of the second report file, the name of the second report file that is a continuation report, the printing start page of the continuation report, etc.
Register the report file name, no continued report, etc.

The printer output means 10 refers to the ``th'' report file entry in the output queue 11 and recognizes that there is a subsequent report.

Then, the first report file is printed, and then printing starts from the printing start page of the second report file.

〔Effect of the invention〕

As explained above, the present invention can automatically remove duplicate pages when outputting to a printer, even if some failure occurs during report transfer between computers and the transfer is interrupted, resulting in some duplicate report pages being transferred. By removing and printing, it is possible to obtain the same output result as if the report transfer was completed without interruption without increasing the processing time.
