JPH1069417A - Resident type file monitoring method - Google Patents

Abstract

PROBLEM TO BE SOLVED: To instantaneously recover a file against its failure. SOLUTION: A personal OS(operation system) 6 always incorporates a driver 1. The setting of the driver 1 is written in a parameter setting file 2, and the operation mode is changed by the change of the parameter value. Thus, a disk volume 5 is always monitored. When an error is detected, the error state is displayed on a display 4. Then a faulty file is recovered in accordance with the error processing guide and the recovery history is outputted to a history file 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a resident file monitoring method, and more particularly to a resident file monitoring method in a personal operating system (OS).

[0002]

2. Description of the Related Art Conventionally, on a personal OS, as a method of monitoring a file state, a method of executing and checking a utility in a batch manner, or a method of starting by designating a time is performed.

[0003]

The first problem is that, even if the file is destroyed in the prior art, there is no other way but to monitor the recovery utility by executing the recovery utility in batches.

The reason is that it cannot be incorporated as a resident program.

[0005] The second problem is that, in the prior art, when monitoring the status of a file, it can only be executed continuously for one logical volume. In addition, the program can be executed only when no other program is accessing the disk.

The reason is that the processing of other programs is hindered.

An object of the present invention is to restore a file instantly when a failure occurs.

[0008]

SUMMARY OF THE INVENTION A resident file monitoring method according to the present invention has a file monitoring program resident in an operating system and monitors whether a file is cyclically destroyed at a timing when there is no disk access. When a file is destroyed, an error message and a processing guide are displayed on the display to restore the file, or when the file is destroyed, the file is restored by the parameters of the parameter setting file of the file monitoring program.

[Operation] Since the file is monitored at all times, it is not necessary to stop other jobs and start them in batches.

[0010]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a resident file monitoring method according to the present invention.

In one embodiment of the present invention, as shown in FIG. 1, a resident driver 1 is incorporated in a personal OS 6. The setting for the driver is written in the parameter setting file 2, and the operation mode can be changed by changing the parameter value.

The disk volume 5 is constantly monitored, and if an error occurs, the status is displayed on the display 4.

The file is restored according to the processing guide. The history is output to the history file 3.

Next, the operation of the first embodiment of the present invention will be described in detail with reference to FIG.

The resident file monitoring driver 1 checks the disk volume 5 and displays a status on the display 4 when an error occurs in the file. The operator inputs the countermeasure from the keyboard 7 and processes the file in which a failure has occurred. When the processing is completed, the history is left in the history file 3.

The operation (check) is performed when the number of accesses to the CPU and the disk is small, so as to avoid the performance degradation of other jobs.

Next, a second embodiment of the present invention will be described in detail with reference to FIG.

In the event of a failure, the guide message may not be displayed on the display 4 but automatically recovered by the parameters in the parameter setting file 2.

[0020]

As described above, the resident file monitoring method according to the present invention has a first effect that a file failure can be quickly detected and recovered.

The reason is that the program is incorporated as a resident program.

The second effect is that file status monitoring can be performed without stopping other programs for accessing the disk.

The reason is that the resident program (driver)
Is executed when the CPU and the disk are free.

Claims (3)

[Claims] 1. A resident file monitoring method, comprising: making a file monitoring program resident in an operating system; monitoring whether a file is destroyed; and recovering the corrupted file when the file is destroyed. 2. A file monitoring program is resident in the operating system to monitor the file cyclically at a timing when there is no disk access for file destruction. If there is a file destruction, an error message and a processing guide are displayed on a display. A resident file monitoring method characterized by displaying and restoring. 3. The resident file monitoring method according to claim 1, wherein when the file is destroyed, the file is restored by a parameter of a parameter setting file of the file monitoring program.
