JPH064352A - Left system informing system for remote maintenance - Google Patents

Abstract

PURPOSE:To detect and inform a management object system which is left for a long time without being maintained when observed from a center system. CONSTITUTION:The minimum access time of the management object system accessed, which was recorded in a management file 1 when access from the center system to the management object system is updated. Concerning all the management object systems, an information processing part 4 calculates lapsed time recorded in the management file 1 from the minimum access day to the current time point, and the identification name of the management object system, for which the lapse of time exceeds a certain fixed access interval critical value, left for a long time without being maintained is displayed on a display device 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abandonment system notification system in remote maintenance.

[0002]

2. Description of the Related Art In the prior art, when a user's system is located at a remote place, a maintenance person connects the center system and the user's managed system with a communication line to monitor the operating state of the system or to take a measure when a failure occurs. We carry out remote maintenance to cope. The maintenance history was managed by the maintenance person himself, and the time when the access for the purpose of maintenance should be performed was decided by the maintenance person himself.

[0003]

In the prior art, there is a possibility that a system to be originally maintained may be omitted due to a memory error of a maintenance person or the like, and there is a managed system left unmaintained for a long period of time. However, there was a problem that the discovery of the managed system, which has a high possibility of failure, was delayed, and that it could not provide a sufficient maintenance service.

[0004]

The abandoned system notification method in remote maintenance of the present invention includes a management file for recording the identification name of the managed system and the minimum access time corresponding to each managed system, and manages from the center system. An update processing unit that updates the last access time of the management file when the target system is accessed, and the time elapsed from the minimum access time to the current time exceeds a certain access interval and is left unmaintained The notification processing unit displays the identification name of the managed system that has been used for a long period, and the display device displays the identification name of the managed system.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In the present embodiment, the management file 1 that records the identification name of the managed system and the last access time corresponding to each managed system, and the management file 1 that corresponds when the center system accesses the managed system The update processing unit 2 that updates the last access time corresponding to the managed system, and the managed system that detects the managed system that exceeds the certain access interval limit value that has elapsed time from the last access time to the present time The system includes a notification processing unit 3 for notifying the maintenance person of the system identification name, and a display device 9 for displaying the management system identification name.

The notification processing unit 3 includes a notification control unit 4 for controlling the notification process, an elapsed time calculation unit 5 for calculating the elapsed time from the minimum access time to the present time for each managed system, and the calculated elapsed time. A comparison / determination processing unit 6 that determines whether or not a certain access interval limit value is exceeded, and a notification target storage unit 7 that stores the identification name of the managed system whose elapsed time exceeds a certain access interval limit value. And a display output processing unit 8 for displaying the identification name of the management target system stored in the notification target storage unit 7 on the display device 9.

FIG. 2 is a flow chart for explaining the operation of the notification processing unit 3 in the embodiment shown in FIG. 1, and FIGS. 3 and 4 are the management file 1 in the embodiment shown in FIG.
It is a figure which shows the example of the file content of.

Considering the case of remote maintenance in which the center system accesses the managed system every 14 days for the purpose of maintenance, the management in which the elapsed time from the last access date is 14 days or more has been considered below. The target system shall be notified to the maintainer. The current date is 91
The date is September 15th.

The operation of the update processing unit 2 will be described. The update processing unit 2 updates the minimum access time of the management target system stored in the management file 1 when the center system accesses the management target system for maintenance purposes.

Next, the operation of the notification processing unit 3 will be described. The notification control unit 4 gives an instruction to the elapsed time calculation unit 5 to calculate the elapsed time of the system 1 out of all managed systems registered in the management file 1. The elapsed time calculation unit 5 calculates the elapsed time A (15 days) by subtracting the minimum access time of the system 1 (August 31, 1991) from the current time (September 15, 1991). 101). The comparison / determination processing unit 6 determines that the elapsed time A (15
Certain access interval limit value B (15 days)
Are compared (step 102). In this case, since A> B, the identification name of the managed system called system 1 is stored in the notification target storage unit 7 as a notification target (step 103).

Next, as in the case of the system 1, the notification control unit 4 gives an instruction to the elapsed time calculation unit 5 to calculate the elapsed time of the system 2. The elapsed time calculation unit 5 is the system 2
The elapsed time calculation unit 5 is instructed to calculate the elapsed time. The elapsed time calculating unit 5 calculates the elapsed time A (12 days) for the system 2 (step 101). The comparison / determination processing unit 6 compares the elapsed time A (12 days) with a certain fixed acceleration interval limit value B (14 days) (step 102). In this case, since A <B, the storage in the notification target storage unit 7 is not performed.

The above steps 101 to 103
The above process is repeated for the system N.

At the time when the processing from step 101 to step 103 is completed for all managed systems, the notification control unit 4 displays the managed system identification name for the notification stored in the notification storage unit 7. The display output processing unit 8 is instructed to do so (step 104). The display output processing unit 8 displays the management target system identification name to be notified on the display device 9.

Although the access interval limit value to be compared with the elapsed time is common to all managed systems in this embodiment, the access interval limit value is individually recorded in the management file as shown in FIG. The unit may compare the elapsed time of each management symmetrical system and the access interval limit value for each managed system. As a result, it is possible to perform detailed maintenance based on the interval limit value that suits the scale and configuration of each managed system.

[0016]

As described above, according to the present invention, the maintenance person recognizes the managed system that has been left unmaintained for a long time as viewed from the center system.
This has the effect of improving the reliability of maintenance technology and enhancing maintenance services.
