Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for performing consistency processing of backed-up system data in a network management system (Network Management System) for managing a network having an exchange or the like as a node.

[0002]

2. Description of the Related Art A network management system (hereinafter referred to as "management system") has been conventionally used as a system for mainly managing a failure or the like occurring in a data communication network. When a failure occurs, the management system acquires information such as a failure location in real time and notifies the management system user of the failure. It also monitors network traffic and the like.

The network management processing is performed by a management system server. The management system server stores system data, and performs network management based on the system data. Here, the system data includes data of the node inclusion relationship that indicates the characteristics of the nodes such as the exchanges (for example, what kind of board is inserted into which slot, etc.). It also includes data on the connection relation between nodes indicating the network state and the hierarchical state (which boards of which switches are connected to each other). The system data is all data for performing such system management and operation. The management system user monitors the state managed by the management system server from a management system console which is a terminal connected to the management system server via a network different from the network to be managed.

Here, for example, when performing maintenance or the like, a recovery process of system data may be performed. The recovery process is a process of calling backed-up system data and storing it on a hard disk or the like in the management system server when recovering the system. The recovery process is performed by a management system user who has a right to stop or start a normal process of the management system, and issues a command for a stop process request, a recovery process request, and a start request of the management system every time the process is completed. This is done by inputting from.

[0005]

However, the conventional management system as described above has the following problems. The first problem is that the management system user issues three commands: a command for stopping the management system, a command for recovering system data, and a command for starting the management system after recovery. It is necessary to input from. Therefore, during that time, the management system user needs to wait for the input of the command, and must spend time for that. Moreover, these commands can only be input by a system administrator of the management system having the authority to stop and start the management system.

[0006] The second problem is that a management system user other than the manager of the management system sharing the management system server has to stop the network management processing operation during the recovery processing. However, it was not possible to know whether it was due to recovery of system data or a failure in the management system without asking an authorized administrator.

Accordingly, the burden on the management system administrator when performing the recovery processing and the like is reduced, and the management system user can recognize that the maintenance of the system data is performed in the management system server. Realization of a simple network management system has been desired.

[0008]
