Abstract

PURPOSE:To update a file remotely from an external file device by controlling file updating status based upon a command to the on-line system side, and at the generation of a system failure after selecting and updating an update file memory, switching the current file to a backup file. CONSTITUTION:When a file 8 in the on-line system 1 is to be updated, the on- line 1 is specified from a control terminal 7 on the basis of a command and a file update mode is specified. Receiving the file update mode, an external maintenance device 3 selects a file updating new file memory 6 in a file memory 4, transfers the contents of the memory 6 to the file memory 8 in the on-line system 1 through a communication circuit and sends a rise command to operate the on-line system on the basis of the new file. If a failure is generated in the on- line system 1, the file memory 6 is switched to a backup operation file memory 5, the contents of the memory 5 are transferred to the file memory 8 to rise the on-line system 1 on the basis of the backup file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a file update method that allows files to be updated remotely from an external file device in an online system such as an electronic exchange or a computer.

[Background of the invention]

Conventionally, file updates have been performed directly by a file update function in the system. Therefore, when there are many systems of the same model, it is necessary to individually prepare files with new contents and go to each system installation location to update the files, resulting in extremely poor update efficiency.

[Object of the Invention] An object of the present invention is to provide a file updating method that enables efficient updating of seven files of electronic exchanges, electronic computers, etc. by remote control.

[Summary of the invention]

The present invention realizes file updates performed independently by the online system by remote control from an external maintenance device, manages the file update status based on commands to the online system, and selects and updates the update file memory. This is designed to switch to the backup file when a new system error occurs.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. In Fig. 1, 1 is an online system, 2 is a communication line, 6 is an external maintenance device, 4 is a file memory, 5 is an operating file memory lJ for backing up the online system, and 6 is a temporary temporary storage of new files for updating files. 7 is a terminal for controlling the external maintenance device, and 8 is a file memory of the online system 1. Here, file 8 of online system 1
When updating the online system 1, the maintenance personnel uses a command or the like from the control terminal 7 to set the speed of the online system 1 and specify the file update mode. The external maintenance device 3 receives it and
Select a new file memory 6 for file update in the file memory 4, and send it to the online system 1 via the communication line 2.
The data is transferred to the file memory 8 of. After the transfer is completed, the external maintenance device R5 detects this and sends a start-up command to the online system 1. Thereafter, system restart processing, which is a function of the conventional online system 10, is started and the system is operated using the new file. Thereafter, the external maintenance device 3 updates the operating status of the online system 8 based on the new file until the file update mode is canceled by the control terminal 7.
It is monitored, and when an abnormality occurs in the online system 1, it switches to the backup operation file memory 5 and performs the same communication as above! 2 to the file memory 8 and start up with the backup file (old contents). If there is no abnormality in the online system 1 within the above-mentioned monitoring period, the file update mode will be canceled automatically or by a command instruction from maintenance personnel from the control terminal 7.
The contents of the new file memory 6 in which the file has been updated are transferred to the backup operation file memory 5. The above is an overview of file update operations.

Next, a software algorithm for so-called file load processing, such as file update mode identification and file selection in file transfer processing, will be explained with reference to FIG.

A file load request is made from the control terminal 7 when updating a file,
It is activated when an abnormality occurs in the online system 1.

Here, the above two examples will be explained. In the former case, the system is normal (step 11L7 since the file update mode is set (step 12), a new file selection process is executed (step 13), and then file transfer is executed (step 14). In the latter case, a system abnormality is notified from the online system 1 in FIG. 1 via the communication line 8, and the external maintenance device then executes the file save process in FIG. 2. In this case, it is determined that the system is abnormal, step 11), backup file selection processing is performed step 15), and 7-aisle transfer is performed (step 14). The rest is the same as above.

As a result of the above, On System's 7 Eye/I/j! This can be achieved using new remote control.

〔Effect of the invention〕

The present invention has the following effects.

(1) Since files can be updated in as many as i online systems using the same file memory, the number of file devices can be reduced, resulting in an economical system configuration.

(2) It becomes possible to update files on multiple online systems simultaneously using the same procedure, and therefore it is expected that the efficiency of file update work will be improved. −

Claims (1)

[Claims] An external maintenance device that is connected to an online system such as an electronic computer or an electronic exchange through a communication line, and collects and updates operating files of the online system,
The system includes an operating file memory for backing up the online system and a new file memory for updating files due to addition of functions, and includes means for specifying file updating by remote control for the online system and identifying the file update status. , has a means for selecting and transferring a file memory with new contents to a specified online system, and a means for switching to a backup operating file memory and transferring it if a system error occurs after updating, A file update method characterized by updating files in an online system.
