Abstract

PURPOSE:To simplify the control of master file information and to improve this control efficiency by updating a master file after dividing it into the areas that can be controlled for their updating by a host computer and a slave computer respectively. CONSTITUTION:The master file of a host computer is updated to a practical master file 9 by the information on updating of master file given from a master maintenance part 4-1. This information on updating is informed to a slave computer via a communication circuit network 3. The slave computer registers the information to an information store faile 11. Then the slave computer updates the master file to a practical master file 14 based on the master file updating information stored in the file 11 and carrying out the new registration, updating and deletion to an item master file 12. When the master file proper to the slave computer is replaced, the file 14 is updated by combining the proper information given from a master maintenance part 4-2 and the file 12.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a master file update method for a computer network, and in particular, the present invention relates to a method for updating a master file in a computer network, and in particular, to centrally process and manage basic master files stored in multiple slave computers with a host computer. This invention relates to a master file maintenance processing method.

〔overview〕

In the master file update method between the host computer and slave computers in a computer network, the master file is divided into areas that can be updated and managed by the host computer and slave computers respectively, and updated, thereby preventing redundancy or increase in master file items. (This simplifies master file information management and makes it more efficient.)

[Conventional technology]

Conventionally, the master file update method for this type of computer network is to have each slave computer have a master file with the same content, format, and structure as the host computer, and update information each time the master file on the host computer is updated. Each slave computer was notified, and the slave computer side updated the master file of each slave computer based on the master file update information. In other words, the master file was collectively managed by the host computer.

[Problem that the invention seeks to solve]

In the conventional master file update method described above, the host computer collectively manages the master file, so the host computer requires a master file that includes unique information (regionality, operability) for each slave computer. In addition, update requests from each slave computer occur frequently and intensively in the master file update process, and the master file update information for each slave computer is also required for multiple slave computers with the same content. Among the master file update information, unnecessary records and items exist on the own slave computer.

Furthermore, it is not easy for the host computer to grasp the master file usage status of each slave computer.

In other words, in the above master file update method, the master file information of all slave computers is centrally managed, which causes redundancy of master file records and a significant increase in the number of items, making master file management complicated for network system operation. There were some drawbacks.

The present invention simplifies master file management without causing redundancy of master file items or increasing the number of items.
The purpose is to provide a more efficient master file update method.

[Means for solving problems]

The present invention provides a system in which one host computer and a plurality of slave computers are formed in a network, and a master file connected to the host computer has an area updated and managed by the host computer and a master file connected to the plurality of slave computers. It is characterized in that it is divided into areas that can be updated and managed by the slave computers, and includes means for notifying master file update information to the slave computers.

[Effect]

The master file is divided into an area that is updated and managed by the host computer and an area that is updated and managed by the slave computer.

Areas that are updated and managed by the host computer are updated by notifying update information from the host computer to the slave computer.

The areas that are updated and managed by the slave computers are updated by the master file update means of each slave computer.
