Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exclusive control method in a network management system in OSI network management, and more particularly, to an operation request from an administrator (manager),
When a managed resource conflicts with an event report generated by itself,
The present invention relates to an exclusive control method for controlling contention by giving priority to a report from a management target.

[0002]

2. Description of the Related Art When focusing on a certain management target, a conventional network management system does not perform exclusive control.
Even if it was performed, the operation for the management target was processed in chronological order.

[0003]

In the above-described conventional network management system, the exclusive control is not performed, or even if the exclusive control is performed, the operation for the management target is processed in order of time. When the operation request is not issued to the managed object, the status of the managed object changes between the time when the operation request is received and the time when the operation is actually performed on the managed object. Although the condition of the operation request may not be satisfied, the operation is performed irrespective of the change of the management target, and there is a problem that a desired operation cannot be obtained.

Further, when exclusive control is performed in the order of time, even if exclusive control is performed in the order of time, only the event report from the management target is suspended, and changes in the management target are ignored. This is similar to the case where exclusive control is not performed, and has the same problem as the case where exclusive control is not performed.

[0005] In view of the above problems, the present invention provides an exclusive control method in a network management system capable of returning a correct result to a network administrator by giving priority to an event report from a management resource. The purpose is to provide.

[0006]

According to an exclusive control method in a network management system of the present invention, an operation request receiving means for receiving an operation request from an administrator and a management resource to be operated are selected from the received operation request. Management target selection means, operation instruction means for executing an operation request for the selected management resource, operation target stack means for storing the selected management resource until the end of the operation request, and receiving an operation result from the management target Operation result receiving means, operation result issuing means for responding the operation result to the administrator, event report receiving means for receiving an event report from the management resource, and judging whether the event report does not conflict with the operation request being executed A conflict checking means for abnormally terminating the conflicting operation request when there is a conflict, and an event report issuing means for notifying the administrator of an event report. There.

Further, there is a conflict checking means for discarding only an operation request to a management resource in which an event report and an operation request conflict.

In addition, there is a conflict checking means for discarding the conflicting management resource operation request and issuing the manager's manipulation request again to the conflicting management resource.

[0009] Further, there is provided an operation object reselecting means for re-evaluating the management resource based on the operation request from the administrator when the operation request is issued again for the resource in which the conflict has occurred.

[0010]

According to the above arrangement, the operation request receiving means receives an operation request from the network administrator, and the operation instructing means instructs the operation to the management resource selected by the operation target selecting means, and the operation request and the management The correspondence with the resource is stored in the operation target stack unit.

The event report receiving means receives the occurrence of the event report from the management resource, notifies the conflict checking means of the event report of the management resource, and notifies the event report issuing means. The conflict checking means refers to the event report and the storage contents of the operation target stack means to determine whether the management resources conflict, and if there is a conflicting operation request, cancels the conflicting operation request. .

Alternatively, only the operation request for the conflicting management resource is discarded.

Alternatively, the previous operation request is discarded and another operation request is issued for the competing management resources.

Alternatively, when an operation request is issued again to a conflicting management resource, processing is performed so that the management resource is evaluated again by the operation target reselection unit based on the operation request from the administrator. In the event of a conflict between the request and the event report from the management resource, the event report is preferentially processed, and a correct result can be returned to the network administrator.

[0015]

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

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention.

In FIG. 1, the operation request receiving means 10 comprises:
An operation request from a network administrator is received, and the received request is instructed to an operation instruction unit.

The operation instructing means 20 instructs an operation to the management resource based on the instructed operation, and simultaneously stores the correspondence between the operation request and the management resource by the operation target stacking means 40. The target management resource is determined by calling the operation target selection unit.

The operation target selecting means 30 determines a management resource to be operated based on the specified operation. The operation target reselecting means 31 determines whether or not the already issued instruction for the management resource is valid after the change of the management resource by the event report.

The operation target stack means 40 stores the correspondence between the operation and the management resource based on the instruction from the operation instruction means 20 until the processing of the operation request is completed.

The operation result receiving means 50 receives the operation result from the management resource and notifies the operation result issuing means 60.

The operation result issuing means 60 returns the operation request result to the administrator.

The event report receiving means 70 receives an event report from a management resource.

The conflict checking means 80 refers to the event report and the operation target stack means 40 to determine whether or not the management resources generating the event reports are in conflict. If there is a conflicting operation request, the following processing is performed. I do.

Cancel a conflicting operation request.

Alternatively, only the instruction for the competing management resource is canceled.

Alternatively, for a competing management resource, the previous instruction is canceled and a new instruction is issued.

Alternatively, for the competing management object,
The operation target reselecting unit 31 determines whether the currently issued instruction is valid. If the instruction is valid, the instruction is left as it is. If the instruction is invalid, the previous instruction is canceled.

The event report issuing means 90 notifies an administrator of an event report from a management resource.

Next, a specific operation of the present invention will be described with reference to the drawings.

FIG. 2 shows a configuration model of the management resources in this description. In FIG. 2, there are two host computers, and each host computer (host 1 and host 2) has three terminals (terminal 1 to terminal 3 for host 1, terminal 4 to terminal 3 for host 2). Model 6) is a connected network. It is assumed that the terminal 1 and the terminal 4 are being used.

First, a first embodiment of the present invention will be described.

In a case where there is no conflict, the network manager issues an operation request to the network management system to "show the use status of the terminal connected to host 1".

Then, the operation request receiving unit 10 receives an operation request “show the use state of the terminal connected to the host 1” from the administrator, and requests the operation instruction unit 20.

The operation instructing means 20 calls the operation object selecting means 30 to select a management resource satisfying the condition "terminal connected to the host 1" from the operation request.

The operation target selecting means 30 knows from the network configuration information inputted in advance that the terminals connected to the host 1 are "terminal 1,""terminal2," and "terminal 3." This is returned to the operation instruction means 20.

Next, the operation instructing means 20 receives the "terminal 1", "terminal 2", and "terminal 3" obtained by the operation object selecting means 30.
To report usage status. At the same time, it instructs the operation target stack 40 to store the correspondence between the operation request and the operation target.

The operation target stack 40 stores a correspondence between an operation request and a management resource.

The network management objects receiving the instruction, that is, the terminal 1, the terminal 2, and the terminal 3 respond to the operation result receiving means 50 with the use state (in this example, only the terminal 1 is in use and the others are not used). I do.

The operation result receiving means 50 includes terminals 1 to 3
And notifies the operation result issuing means 60 of the response. At the same time, assuming that the operation has been completed, the operation request to the terminal 1, the terminal 2, and the terminal 3 is deleted from the operation target stack.

The operation result issuing means 60 notifies the administrator of the result from the operation result receiving means 50.

If the use of the terminal 2 is started after the request from the network administrator is completed,
This is notified to the event report receiving means 70.

The event report receiving means 70 notifies the conflict checking means 80 that an event report has been received from the terminal 2 and notifies the event report issuing means 90.

The conflict checking means 80 checks whether or not an operation has been performed on the "terminal 2" by referring to the operation target stack means 40, and does not perform any operation since no operation request has been made.

The event report issuing means 90 notifies the administrator of the event report from the "terminal 2".

Next, a description will be given of a case where a similar operation request is received and the use of the "terminal 2" is started before the request from the administrator is completed in a case where there is a conflict.

The process from receiving an operation request from the network administrator to issuing an instruction to the network management target is the same as in the case where there is no conflict, and therefore will not be described. (Operation request receiving means 10, operation instructing means 20, operation target selecting means 30,
Here, when the use of the terminal is started, an event report indicating that “the use has been started” is generated from the terminal 2.

The event report receiving means 70 notifies the conflict checking means 80 that an event report has been received from the terminal 2 and notifies the event report issuing means 90.

The conflict checking means 80 checks whether an operation corresponding to “terminal 2” has been performed or not.
In this case, it is known that the operation request for the terminal 2 is being executed, and since the terminal 2 is applicable, the operation request from the network administrator is canceled and the operation result is issued. It instructs the means 60 to respond that "the operation request has been discarded".

The event report issuing means 90 notifies the administrator of the event report from the “terminal 2”.

The operation result issuing means 60 notifies the administrator that the operation request has been discarded. Thereafter, the network administrator can obtain the correct result by making the same request again.

Next, a second embodiment of the present invention will be described.

In the case where there is a conflict, a case will be described in which the same operation request as in the first embodiment is received and the use of "terminal 2" is started before the request from the administrator is completed. .

Until an operation request is received from the network administrator and an instruction is issued to the network management target, the first
Since it is the same as that of the embodiment, it is omitted. (Corresponding to the processing of the operation request receiving means 10, the operation instructing means 20, the operation target selecting means 30, and the operation target stack 40) Here, when the use of the terminal 2 is started, the terminal 2 issues a message indicating that the use has been started. An event report occurs.

The event report receiving means 70 notifies the conflict checking means 80 that an event report has been received from the terminal 2 and notifies the event report issuing means 90.

The conflict checking means 80 checks whether an operation corresponding to “terminal 2” has been performed or not.
In this case, it is found that the terminal 2 is applicable, and the processing for the terminal 2 is canceled.

The event report issuing means 90 notifies the administrator of the event report from the "terminal 2".

Thereafter, the operation results from the terminals 1 and 3 are reported to the network administrator in the same manner as in the first embodiment.

Next, a third embodiment of the present invention will be described.

In the case where there is a conflict, the case where the same operation request as in the first embodiment is received and the use of "terminal 2" is started before the request from the administrator is completed will be described. .

Until an operation request is received from a network administrator and an instruction is issued to a network management target, the first
Since it is the same as that of the embodiment, it is omitted. (Corresponding to the processing of the operation request receiving means 10, the operation instructing means 20, the operation target selecting means 30, and the operation target stack 40) Here, when the use of the terminal 2 is started, the terminal 2 issues a message indicating that the use has been started. An event report occurs.

The event report receiving means 70 notifies the conflict checking means 80 that an event report has been received from the terminal 2 and notifies the event report issuing means 90.

The conflict checking means 80 checks whether an operation corresponding to “terminal 2” has been performed or not.
In this case, the terminal 2 knows that it is applicable, cancels the processing for “terminal 2”, and issues an operation request to “terminal 2” again.

The event report issuing means 90 notifies the administrator of the event report from the “terminal 2”. Thereafter, the search results from the terminals 1 and 3 are reported to the network administrator in the same manner as in the first embodiment.

Thereafter, the operation results from the terminal 1 and the terminal 3
The operation result requested again from the terminal 2 is reported to the network administrator in the same manner as in the first embodiment.

Next, a fourth embodiment of the present invention will be described.

In a case where there is a conflict, when an operation request similar to that of the first embodiment is received, the “terminal 7” (not shown) is switched to the “host” until the request from the administrator is completed. A case where a new connection is made to "1" will be described.

The first operation request is received until an operation request is received from the network administrator and an instruction is issued to the network management target.
Since it is the same as that of the embodiment, it is omitted. (Corresponding to the processing of the operation request receiving unit 10, the operation instruction unit 20, the operation target selection unit 30, and the operation target stack 40) Here, when the terminal 7 is connected to the host 1,
An event report “connected to host 1” is generated.

The event report receiving means 70 notifies the conflict checking means 80 that an event report has been received from the terminal 7, and notifies the event report issuing means 90.

The conflict checking means 80 checks whether the operation corresponding to the “terminal 7” has been performed or not.
, And knows that the operation is not applicable, and then calls the operation target reselecting means 31 to check whether the terminal 7 corresponds to the currently executed operation request.

The operation object reselecting means 31 knows that the terminal 7 corresponds to the “terminal connected to the host 1”,
That fact is returned to the conflict inspection means 80.

The conflict check means 80 subsequently issues an operation request to the terminal 7 and instructs the operation target stack means 40 to store it.

The event report issuing means 90 notifies the administrator of the event report from the "terminal 7".

Thereafter, the operation results from the terminal 1, the terminal 2 and the terminal 3 and the operation result requested again from the terminal 7 are
It is reported to the network administrator in the same manner as in the first embodiment.

[0075]

As described above, the exclusive control method in the network management according to the present invention can return the correct result to the network administrator by processing the event report from the management resource preferentially. There is an effect that there is.

Further, since the event report is prioritized, it is possible to promptly provide the network manager with an “abnormal situation of network resources” which is important for the network manager.
