  In the above prior art, it is necessary to stop the business while distributing programs and files. This method increases the data transfer time as the number of distributed computers, terminals, etc. and the amount of data to be updated increase. If the distribution time increases due to an increase in the line usage rate, etc., and the business cannot be stopped for a long time, there is a problem that it cannot be used.

  Also, in order to shorten the distribution time of one time, when distributing the program in several times (several days), the program distribution work must be performed many times, and the work is difficult, There is also a problem that errors are likely to occur.

  Furthermore, in the above prior art, since the distribution source and distribution destination of programs and files are managed on a one-to-one basis, if a plurality of distributed computers and terminals are connected in multiple hierarchies, lower layer distribution management cannot be performed. There is also a problem.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described problems in the prior art, and in particular, to distribute programs and files in a computer system connected in a multiple multiplex hierarchy. An object of the present invention is to provide a processing method, a distribution method and a transmission method using a computer that can be scheduled and can be divided and distributed by one instruction, simplify distribution work and distribution management, and prevent errors.

  The above object of the present invention is a processing method using a computer, wherein the computer starts distribution of a program, the order of sending the program, execution of the program, creation of a work file, deletion of a work file, This is achieved by a processing method characterized in that information including at least one instruction of program copy and program merging is sent to another computer, and the other computer is caused to execute processing according to the information including the instruction.

  Also, a method of sending a program using a computer, when sending a program from a first computer to a second computer, the schedule information stored in advance in the first computer and stored in advance in the second computer This is achieved by a method of sending a program, wherein the program is sent from the first computer to the second computer in synchronization with the schedule information.

  Also, a method of sending a program using a computer, wherein the computer refers to schedule information stored in advance in the computer at the time of startup, and waits for the time to send the program included in the schedule information to another computer. This is achieved by a method of sending a program, characterized by sending the program.

  The above processing eliminates the need for batch program and file distribution from the host computer and facilitates system update and operation.

As described above in detail, according to the present invention, there is a remarkable effect that data distribution using a schedule file can be realized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 2 is a configuration diagram showing a computer system including a host computer and a plurality of distributed computers for executing the file distribution method according to the embodiment of the present invention.

In the figure, a host computer 11 and a plurality of distributed computers 21 are connected by a line 1. The host computer 11 has a schedule file 12 that stores distribution schedules of programs and files, a distribution program file 13 that stores programs to be distributed to the distributed computers 21, and a distribution file 14 that stores files to be distributed to the distributed computers 21. Further, the host computer 11 executes a distribution management program (host) 15.

  On the other hand, each distributed computer 21 in the system has the same schedule file 22 as the schedule file 12 on the host computer 11 side, an update program file 23 to be updated, and an update file 24. The distributed computer 21 executes a distribution management program (distribution) 25. Furthermore, the distributed computer 21 allocates work files 26 necessary for program distribution as needed.

  The above distribution management program (host) 15 and distribution management program (distribution) 25 refer to the respective schedule files 12 and 22 and transfer the distribution program file 13 and distribution file 14 to the distributed computer 21 in accordance with this. The update program file 23 and the update file 24 are updated.

  FIG. 3 shows an example of part of the contents of the schedule file 12 when the program and file are distributed in two days in the configuration shown in FIG. In FIG. 3, the ACTION control statement 30 specifies that the program is to be distributed at 19:00 on January 10, 1990. The procedure necessary for program distribution is specified by the following OPERATION control statement. The OPERATION control statement group 31 creates a work file 26, transfers the distribution program file 13 to the work file 26, merges the program in the received work file 26 with the update program file 23, and finally, the work file 26 Is specified to be deleted.

  The ACTION control statement 32 specifies that file distribution is to be performed on January 17, 1990 at 17:00. The OPERATION control statement group 33 creates a work file 26, transfers the distribution file 14 to the work file 26, copies the program in the received work file 26 to the update file 24, and finally saves the work file 26. It is specified to be deleted.

  FIG. 1 shows the flow of processing of a distribution management program (host) 15 that performs program distribution and a distribution management program (distribution) 25 with reference to the schedule file shown in FIG.

  When started, the distribution management program (distribution) 25 refers to the schedule file 22 and sets the next distribution date and time from the current time (step 40). When the distribution time is reached (step 41), control statements are sequentially input from the schedule file 22 (step 42). Then, according to the control statement, a work file 26 is created (step 44), and file transfer is performed in synchronization with the host (step 45). The received data is merged or copied (step 46 or 47).

  Finally, in step 48, the work file 26 is deleted.

  Similarly, when the distribution management program (host) 15 is started, the schedule file 12 is referred to and the next distribution date and time is set (step 50). When the distribution time is reached (step 51), control statements are sequentially input from the schedule file 12 (step 52). Thereafter, the host side only performs file transfer, and nothing else.

  When an ACTION control statement is input, the distribution management program (distribution) 25 and the distribution management program (host) 15 both retrieve the next distribution execution date and wait for the distribution time (steps 43 and 53). The above processing is repeated to distribute the program and file in two days.

In the above embodiment, the host computer 11 distributes the same schedule file storing instructions such as the date and time when distribution is started, the distribution order of programs and files, creation and deletion of work files, execution of necessary programs, etc. Since it can be distributed to the computer 21 at any time and the host computer 11 and each distributed computer 21 can synchronize with each other by referring to the schedule file, the program and file can be distributed. This has the effect of making it easier and preventing errors.
In addition, according to the present invention, a schedule file storing a distribution schedule of programs and the like is distributed to each computer or terminal constituting the computer system, and distribution of programs and the like from the host computer to the distributed computer is performed. Is performed using the schedule file in a synchronized manner, so that divisional distribution is possible with a single instruction, processing using a computer that simplifies distribution work and distribution management, and prevents errors The method, distribution method and delivery method can be realized.

  Next, a second embodiment of the present invention will be shown. In this embodiment, the file distribution from the host computer to the distributed computer is performed in two days according to the line performance, and the file is distributed to the terminal on the same day.

  FIG. 4 is a block diagram showing a computer system comprising a host computer, a plurality of distributed computers, and a plurality of terminals for executing the program distribution method according to the second embodiment of the present invention, and FIG. A part of the contents of the schedule file in the example is illustrated.

  The internal configurations of the host computer 60 and the distributed computers (A) 61 and (B) 62 shown in FIG. 4 are the same as those of the host computer 11 and the distributed computer 21 shown in FIG. The internal configuration is similar to this.

  In this embodiment, similar to the above embodiment, the same schedule file is distributed between the host computer 60 and the distributed computers (A) 61 and (B) 62 at an arbitrary time point. The program or file is transferred as described below in synchronization between the host computer 60 and the distributed computers 61 and 62 using the above.

  That is, by the ACTION control statement 70 and the OPERATION control statement 71 in FIG. 5, the file 65 of the host computer 60 is changed to the file 66 of the distributed computer (A) 61 on February 1, 1990, as in the above-described embodiment. Forwarded. However, since the ACTION control statement 70 is intended only for the distributed computer (A) 61, it is not transferred to the distributed computer (B) 62. The file transfer to the file 67 of the distributed computer (B) 62 is performed on February 2, 1990 by the ACTION control statement 72 and the OPERATION control statement 73. At this time, the data is not transferred to the distributed computer (A) 61. By processing as described above, the file transfer to the distributed computers (A) 61 and (B) 62 can be divided into two days.

  On February 2, 1990, the ACTION control statement 74 and the OPERATION control statement 75 were used to transfer the file from the file 66 on the distributed computer (A) 61 to the file 68 on the terminal 63, and on the distributed computer (B) 62. The file transfer from the file 67 to the file 69 of the terminal 64 is performed simultaneously, and the file distribution to the terminal is performed simultaneously.

  Also in the above embodiment, the host computer 60 distributes the same schedule file to each distributed computer and terminal at an arbitrary time, and refers to this schedule file so that the host computer 60 and each distributed computer and distributed computer Since programs and files can be distributed while synchronizing with the terminal, it is easy to instruct and manage, and errors can be prevented.
