Abstract

PURPOSE:To improve file transfer efficiency when a fault occurs by designating an address into the data on a transfer file when data are registered and at the same time adding the message serial numbers into the data on the transfer file. CONSTITUTION:A host computer 100 includes an inter-computer file transfer device 110, a batch application 120, and an on-line application 130. Then an address is designated into the data on a transfer file when data are registered and the file transfer is carried out between the computers 100 based on said designated address. At the same time, the message serial numbers are added to the data on the transfer file and the processing is started at the data of the relevant message serial number when a fault is restored. Furthermore an application suited to the application form is used and a transmission type is designated into the data on the transfer file. Then the application is started according to the designated transmission type when the transfer file is received. Thus it is possible to set the priority among plural transfer files for simultaneous transfer of files by designating a class name into the data on the transfer file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for transferring files between host computers of a distributed processing online device.

〔overview〕

The present invention provides a method for transferring files between host computers of a distributed processing online device, in which a destination is specified in the data of a transfer file at the time of data registration, a message sequence number is added to the data of the transfer file, and an online application and a batch application are By integrating it, files can be transferred between multiple computers connected in tandem, improving the efficiency of file transfer in the event of a failure and reducing the burden on the operator.

[Conventional technology]

Conventional file transfer devices between host computers are mainly batch-type file transfer devices, and transaction-type file transfers between multiple host computers are not possible, and in the event of a failure during multiple transfers, data is transferred from the beginning of the file. In addition, it was not a unified file transfer device between host computers that included applications and terminals.

[Problem that the invention seeks to solve]

Such conventional computer-to-computer file transfer devices are
As mentioned above, since the data does not have a destination, files cannot be transferred between multiple host computers connected in tandem, and if a communication failure occurs during file transfer, messages cannot be sent to the data. Because it does not have a serial number, it is necessary to resend the file from the beginning, making file transfer inefficient.Furthermore, since the device does not integrate a terminal, online application, and batch application, the burden on the operator is heavy. There were drawbacks.

The present invention solves the above-mentioned drawbacks, and allows file transfer between multiple host computers connected in tandem, which improves the efficiency of file transfer in the event of a failure (and reduces the burden on the operator). The purpose is to provide a method.

[Means for solving problems]

The present invention provides an inter-computer file transfer method for a distributed processing online device that transfers data including data generated from online applications, batch applications, and terminals between three or more host computers. Specify the destination, perform file transfer between the above host computers according to the specified destination, add a message sequence number to the data of the transferred file, restart from the message sequence number when a failure occurs, and transfer. The present invention is characterized in that an online or batch transmission type is specified in the file data, and an application is started according to the specified transmission type when the transfer file is received.

[Effect]

A destination is specified in the data of the transfer file at the time of data registration, and files are transferred between host computers according to the specified destination. In addition, a message sequence number is added to the data of the transfer file, and when recovery after a failure occurs, the message sequence number is restarted, and the transmission type is specified in the data of the transfer file by using an application suitable for the usage type. , launch the application according to the transmission type specified when receiving the transfer file.

By specifying a class name in the transfer file data, you can set the priority of multiple transfer files and transfer them simultaneously.

The above operations enable file transfer between multiple tandem-connected computers, improve the efficiency of file transfer in the event of a failure, and reduce the burden on the operator.
