Abstract

PURPOSE:To reduce a file collection time and to decrease capacity of a magnetic disk on the remote maintenance system by collecting only a difference in an exchange file in the remote maintenance system. CONSTITUTION:Every time data is written in a file memory 16 from a central processing unit 10, address information and data sent from a file memory data processor 14 are stored by one day's share and the result is preserved as a preceding data difference file LAFA. The difference information is added to the difference file LAFA at the end of the date similarly in the succeeding day to revise the preceding data difference file LAFA. Then a guarantee file REF is sent to an external storage device (EX.MT) once per week and the date difference file LAFB is copied to the preceding data difference file LAFA at that time to revise the guarantee file and the preceding date difference file. Thus, the collection time of the exchange file is reduced and the file capacity of the magnetic disk is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a file collection method in a remote maintenance system.

[Conventional technology] The conventional method of collecting files in a remote maintenance system is as follows:
- Once a day, first, the previous day's files for the system were sent to the exchange, and if the comparison result with the current status was normal, all the exchange files were collected and stored on the magnetic disk of the remote maintenance system. .

[Problems to be solved] As described above, in the conventional file collection method, all exchange files were collected once a day and stored on the magnetic disk on the remote maintenance system. The problem is that file collection (comparison and collection) takes too much time in proportion to the size of the exchanger file, and (b) the file capacity on the magnetic disk increases, resulting in a shortage of disk capacity. there were.

The present invention has been made in view of these conventional problems, and its purpose is to shorten the collection time of exchange files and to reduce the file capacity of magnetic disks used in remote maintenance systems. The objective is to provide a method for collecting files in a maintenance system.

[Means for Solving Problems] In order to achieve the above object, the present invention includes a step of transmitting the address and data to a remote maintenance system when writing to a file memory on the exchange side; a management step for managing the addresses and data sent from the exchange on the remote maintenance system side, and the management step is configured to store the addresses and data sent from the exchange in a memory and manage the difference with the guarantee file. has been done.

[Example] Next, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a preferred example of a file collection method in a remote maintenance system according to the present invention, in which 100 represents an exchange and 200 represents a remote maintenance system.

The exchange 100 includes a central processing unit 10, a data channel 12, a file memory data processor 14, a file memory 16, and a monitoring test information aggregating device 18.

The monitoring test information aggregation device 18 is configured to manage an interface with the remote maintenance system 200, and also controls the file memory data processor 1.
4 is configured to send the write address and data to the remote maintenance system 200 via the aggregation device 18 when data is written from the central processing unit 10 to the file memory 16.

Further, the remote maintenance system 200 includes a central processing unit 2
0 and a magnetic disk 22, the magnetic disk 2
On 2 are the guarantee file REF and the previous day's difference file LA.
FA and today's difference file LAFB are provided.

A feature of the present invention is that a remote maintenance system collects files so as to manage backups of exchange files differentially.

Next, a file collection method using differential files according to the present invention will be explained.

First, when starting up the system, the remote maintenance system 200
collects all data and addresses on the file memory 16 of the exchange 100 and stores them in the magnetic disk 22 as a guarantee file REF.

After the system is started up in this way, switch 1
Every time data is written from the central processing unit 10 of 00 to the file memory 16, address information and data sent from the file memory data processor 14 are accumulated for one day, and this is saved as the previous day's difference file LAFA. .

The next day, the addresses and data sent from the exchange 100 are similarly created into a difference file for the day and stored as AFB, and at the end of the day, difference information is added to the difference file LAFA for the day, and the difference file LAFA for the previous day is updated.

In this embodiment, this data updating operation is repeated for one week.

Then, the guarantee file REF is sent to the external storage device (EX, MT) once a week, but at this time, the information in the previous day's difference file LAFA is overwritten on the guarantee file REF,
Today's difference file LAFB is the previous day's difference file LA
By copying to FA, the guarantee file and the previous day's difference file are updated.

[Effects of the Invention] As explained above, according to the present invention, by collecting exchange files in a remote maintenance system using only differences, file collection time can be shortened, and the magnetic This has the effect of reducing the file capacity of the disk.

Further, according to the present invention, since only the differences in exchange files are collected every day, it is possible to manage the history of changes in exchange files.
