Abstract

PROBLEM TO BE SOLVED: To reduce time for transferring a file and to reduce an operator's load and judging mistakes by providing a control means for receiving information on the failure of line connection processing and automatically scheduling again when a transmission processing means sorts communication opposite parties to the order of plural lines and fails in line connection processing. SOLUTION: The schedule control means 5 retrieves transmission data files 4A, 4B,...4Z and lines up the communication opposite parties in the order of many pieces of data to store in a transmission schedule file 6. The transmission processing means 7 collectively file-transfers file pieces of transmission data stored in the transmission data files 4A, 4B,...4Z to each opposite party in the order of storing in the transmission schedule file 6. When the transmission processing means 7 fails in line connection with an opposite party, a re-schedule control means 9 receives connection failure information through a connection failure information file 8 and carries down the transmission order to the opposite party according to a fixed rule to execute re-schedule.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a batch file transmission scheduling method, and more particularly to a batch file transmission scheduling for collectively transmitting transmission data stored in a host computer to a plurality of destinations using a public line network. Regarding the scheme.

[0002]

2. Description of the Related Art In a computer system in which a host computer and a plurality of distributed computers are connected via a public line network, transmission data sequentially generated by the host computer and transmitted to different destinations are stored in a file for each destination. Conventionally, batch transmission of files has been performed in which both the line connection processing time and the data transfer time can be shortened by batch-transferring files to each distributed computer in batch processing at a certain point.

In the conventional batch file transmission process,
The order of destinations to be transmitted is fixedly determined in advance, and when the host computer can use a plurality of subscriber lines in parallel, the order of destinations may be determined for each line. Also, when line connection processing is performed in the determined order, if the connection fails because the other party's distributed computer is communicating with another or is not ready for reception, it is displayed as transmission processing failure. Alternatively, a transmission failure report is made by printing, and the transmission process for the next destination is started.

In Japanese Patent Application Laid-Open No. 1-280961, image information that is input at any time is stored in a memory so that it can be searched for by destination, and the image information accumulated when a certain condition is satisfied is sorted by destination. A facsimile device that collectively transmits at once is disclosed. In this example, only one communication line is used, and the transmission order is configured to give priority to the destination of the previously input image information, and when the line connection processing with the destination fails. No mention is made of the correspondence.

[0005]

As described above, in the conventional file batch transmission processing, the line connection processing is performed in a predetermined order, and if the connection fails, the transmission processing fails and the batch transmission processing is performed. Since it is placed outside the frame of (1), it is necessary to perform retransmission processing manually by the operator's judgment, which is a burden on the operator and there is a drawback that transmission error and transmission delay due to operation mistake cannot be avoided.

Further, since the order of destinations to be transmitted is fixedly determined irrespective of the amount of data to be transmitted, the use time tends to vary among a plurality of lines used in parallel, and the line use efficiency becomes low. There is a drawback that the entire processing time of batch file transmission becomes long. This problem becomes particularly noticeable when the order of the destination is determined for each line.

The object of the present invention is to eliminate the above-mentioned drawbacks,
Provides a batch file transmission scheduling method that makes it possible to reduce the overall processing time by making the usage time of multiple parallel lines almost even, and to automatically perform retransmission processing for the other party who failed in line connection processing. To do.

According to a file batch transmission scheduling method of a first aspect of the present invention, a host computer and a plurality of distributed computers are connected to each other via a public line network, and are sequentially generated by the host computer. In a file batch transmission scheduling method for storing transmission data of different destinations in a file for each destination and batch-transferring files to each of the distributed computers in batch processing at a certain time, preset in the host computer When the conditions are met, a schedule control unit that searches the transmission data file in which the transmission data is stored for each destination and determines the transmission order in the order of the destination having the largest number of transmission data, and the schedule control unit in the order determined by the schedule control unit. Send data file to the other party A transmission processing unit that collectively transmits the accumulated transmission data, and a reschedule that, when the line connection with the destination by the transmission processing unit fails, delays the order of transmission to the destination according to a certain rule and reschedules. And a control means.

According to a second aspect of the present invention, there is provided a file batch transmission scheduling method according to the first aspect of the present invention.
The transmission data file is searched at a preset time to determine the transmission order.

According to a file batch transmission scheduling method of claim 3, in the file batch transmission scheduling method of claim 1 or 2, the re-scheduling control means sets the transmission order to the other party to which the line connection has failed first. The feature is that the number is moved down by n (a positive integer) when it fails, and the schedule is rescheduled to the end when the same partner fails the second time.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings.

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

As shown in FIG. 1, the file batch transmission scheduling system of this embodiment is a host system in which a host computer 1 and a plurality of distributed computers 2A, 2B ... 2Z are connected by a public line network 3. The computer 1 searches the transmission data files 4A, 4B ... 4Z for accumulating sequentially generated transmission data of fixed data length for each destination and the transmission data files 4A, 4B .. 4Z at a predetermined time. ,
Schedule control means 5 for arranging the destinations in descending order of the number of transmission data and storing them in the transmission schedule file 6.
And a transmission processing means 7 for collectively transferring a plurality of transmission data stored in the transmission data files 4A, 4B, ... 4Z to each destination in the order stored in the transmission schedule file 6, and a transmission processing means 7. Is connected to the other end, the connection failure information is received via the connection failure information file 8 and the reschedule control means 9 is provided to carry out rescheduling by lowering the transmission order to the other end according to a certain rule. Is configured.

The schedule control means 5 sends the transmission data files 4A, 4A when the predetermined time comes.
B ... A schedule record for searching 4Z and managing the transmission status is created for each destination, and stored in the transmission schedule file 6 arranged in the order of the destination having the largest number of transmission data items. In the transmission schedule file 6, as shown in FIG. 2, a schedule record having items of transmission status, serial number (transmission order), destination code, number of data, and number of reschedules is created for each destination, and data is recorded. The data are sorted and stored in order of the number of records.

When the process of storing the schedule records for all the destinations in the transmission schedule file 6 is completed, the transmission processing means 7 causes the schedule records to follow the sequence number sequence (the record number and the sequence number are the same when initially stored). Then, the transmission process is started to the distributed computer corresponding to the destination code. At this time, the transmission status of the corresponding schedule record in the transmission schedule file 6 is updated from non-transmission to transmission. As the transmission process, first, an unused line is selected from a plurality of subscribed lines, the destinations are assigned in the order of serial numbers, and the line connection process is performed. When the connection is completed, the transmission data accumulated in the corresponding transmission data file is transferred collectively, and when the transfer is completed, the connection with the other party is released and the line is used with the next party. Start the connection process. In line connection processing,
If the connection cannot be established with one dialing and calling process, the line is held and the redialing and calling process is performed a specified number of times at a specified time interval. Start line connection processing with the untransmitted destination. When the host computer 1 is equipped with a plurality of subscriber lines, data transfer to a plurality of destinations up to the number of subscriber lines installed can be performed in parallel. When the transmission process to one destination is completed,
The transmission processing means 7 updates the transmission status of the corresponding schedule record in the transmission schedule file 6 to normal end,
The transmission process is started for the destination with the lowest serial number that has not yet been transmitted. When there is no untransmitted transmission status in the schedule record of the transmission schedule file 6, the next transmission processing is not started and the transmission on that line is ended. When the transmission processing on all the lines is completed, the file batch transmission processing is executed. Complete.

As described above, the schedule control means 5
Stores the schedule records in the transmission schedule file 6 by arranging the schedule records in the order of the destinations with the largest number of transmission data items, and the transmission processing means 7 sorts the destinations with the largest number of transmission data items into a plurality of subscriber lines in order. The usage time of the subscriber lines can be made almost equal, and the total processing time required for batch file transfer can be shortened.

Next, the flow of processing when the transmission processing means 7 fails in the line connection processing with the other party at the beginning of the transmission processing will be described. When the transmission processing means 7 performs the line connection process to the other party, the other party's line is in the BUSY state, or the receiving program of the other party's distributed computer is not activated, and therefore a predetermined number of redial calls are made. When connection fails due to connection failure even after repeating the process, the transmission processing means 7 passes the connection failure information to the reschedule control means 9 via the connection failure information file 8,
The process proceeds to the next untransmitted schedule record on the subscriber line.

The re-schedule control means 9 updates the transmission status of the schedule record of the other party concerned from transmission to connection abnormal according to the connection failure information, and at the end of the transmission schedule file 6, the corresponding schedule record in which the connection abnormality occurred. Copying is performed, the transmission status is set to non-transmission, the serial number is updated to the original serial number by adding a fixed number n (n is a positive integer), and the rescheduling count is updated to 1 to obtain a rescheduling record. register. At this time, if there is a registered schedule record with the same serial number,
1 in the serial number of each record after the schedule record
Is added and the serial number is sequentially lowered and updated.

The above processing will be described by a concrete example with reference to FIG. In FIG. 3, during the processing of the schedule record shown in FIG. 2, the line connection process for the destination (C) having the record number “2” fails and the reschedule control means 9
Shows that the reschedule by is completed. In this example, the number of equipment lines of the host computer 1 is 3, and the addition constant n for carrying back the serial numbers at the time of reschedule is 5
Shows the case. The transmission process for the record number “1” is normally completed by the # 1 line of the three subscription lines, and the transmission process for the record number “4” is in progress. The line connection processing for the record number "2" by the # 2 line becomes a connection failure after a predetermined number of redials, and the transmission processing means 7 stores the connection failure information in the connection failure information file 8 and then the transmission processing for the record number "5". Is in progress. Also, the transmission processing for the record number "3" is proceeding in parallel by the # 3 line. Upon receiving the connection failure information, the reschedule control means 9 updates the transmission state of the record number "2" to abnormal connection, and copies the record content to the record number "101". afterwards,
The transmission status of the copied records is not transmitted, and the serial number is n = 5
Is added to update the number of reschedules to 1, and is registered as a reschedule record. Finally, record numbers "7" to "10" that are the same as the updated serial numbers
The processing is ended by sequentially lowering the serial numbers up to "0". FIG.
In the figure, the schedule record related to the rescheduled partner is displayed in a shaded manner. After this,
According to the contents of the updated transmission schedule file 6 shown in FIG. 3, the transmission process is sequentially started for the destination whose transmission status is untransmitted and has the smallest serial number. It should be noted that the addition constant n for carrying down the serial number is preferably set to a value larger than the number of equipment lines as in this specific example, but it is complicated because the serial number updating process needs to be changed depending on the situation. It is also possible to set it to be less than a number.

FIG. 4 is a rescheduling control means 9 when the line connection to the same destination (C) fails again as a result of the transmission processing according to the contents of the updated transmission schedule file 6 shown in FIG. The processing result of is shown. That is, the rescheduled record number “1
If the line connection process for "01" fails, after updating the transmission status of record number "101" to connection error,
A new record is created by copying the contents into the record number "102", and the serial number is the number after the final serial number. That is, in the case of the first connection failure, by reschedule as soon as possible, the destination is distributed to a plurality of subscribed lines in the order of the destination with the largest number of transmission data,
We tried not to disturb the purpose of making the usage times of multiple subscriber lines almost equal, but in the case of a second connection failure, there is a possibility that connection failure will occur again even if it is rescheduled earlier. It is configured to reschedule to the final ranks, as more will be. If the connection processing according to the rescheduling of the final order also fails, a transmission failure report is made as a failure of the transmission processing, and the operator is left to judge.

In the above description of the embodiment, it has been explained that the schedule control means stores the schedule record in the transmission schedule file at a predetermined time set in advance. The schedule creation time by the schedule control means is not limited to this. For example, it may be performed when the transmission data amount exceeds a certain amount, or the transmission data amount and the time may be used together. Good.

Further, the re-schedule control means copies the relevant schedule record in which the connection is abnormal to the end of the transmission schedule file, sets a new serial number to which the constant n is added, and sets the same serial number that has already been registered. Although only the serial numbers after the schedule record are moved down in order, the records may be rearranged according to the updated serial number. In this case, the record number and the serial number are always the same, and the transmission processing means Will always process the schedule records in the order in which they were stored.

Further, the re-schedule control means sets 3 if the line connection processing for the same destination fails twice.
Although the re-scheduling is performed so that the line connection process for the second time is performed last, the re-scheduling for adding n to the serial number may be repeated a plurality of times.

[0024]

As described above, in the file batch transmission scheduling method of the present invention, the schedule control means determines the transmission order in the order of the destinations having the largest number of transmission data items, and the transmission processing means assigns the destinations to a plurality of destinations. Since the lines are allocated to the lines in order, the use times of the plurality of lines can be made almost equal, and the total processing time required for the batch file transfer can be shortened. Further, when the transmission processing means fails in the line connection processing with the other party, the reschedule control means for receiving the information and automatically rescheduling is provided, so that there is an effect that the operator's load and judgment error can be reduced.
