Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing method for managing an object which is a data unit of a system in a computer system network.

[0002]

2. Description of the Related Art In a network in which a plurality of computer systems are connected, for example, the following method is used to manage information about network resources referred to by a communication management program of each system. There are cases.

That is, each resource, for example, information for each terminal or the like is called a data unit as an object. For example, each computer system holds and manages an object relating to a resource under its own direct control, and another computer system. If necessary for the resource under the control of, the other computer system having the object is inquired.

In this case, in order to manage those objects as a network, for example, a tree structure of hierarchical relation of names is provided, each terminal node thereof is associated with each object, and as shown in FIG. Each B manages a part of the tree structure.

In the tree structure of names managed by each system, the objects corresponding to each end node include all objects held by the computer system, and these objects are used as real name objects, and the names determined by the tree structure (real name and Yes).

The object to which the end node corresponds is
In addition to the real name object of its own, there is an object of control information for accessing the real name object of another computer system required by the computer system, and this object is an alias object, and a name similarly defined in the tree structure (also called an alias ).

For example, in FIG. 2, "D" of system B
When a node (a node identified by the name “A.C.D”, but simply referred to as D etc. in the following description for simplicity) is a real name object, the system A refers to this object. If necessary, for example, an "O" node is provided as a node of the alias object, and the name "D" of the real name object and the "system A" and the address etc. are recorded in the object as information indicating the location.

If there is a relation between the real name and the alias, and the name of the real name object is changed to "X" for the convenience of the system B, for example, the alias object "O" of the system A will exist. It is obvious that there is an inconvenience because the object "D" that does not exist is instructed.

It is an object of the present invention to provide an object management processing method for automatically maintaining the matching relationship between a real name object and an alias object.

[0010]

FIG. 1 is a flow chart of processing showing the configuration of the present invention. The figure shows a configuration of an object management processing method, which is a network in which a plurality of computer systems are connected, and each computer system is under the control of the computer system, and an object identified by a real name is a real name object. And a predetermined control information required to access each real name object of another computer system that requires access from the computer system as an alias object identified by each alias Is.

An alias management book is provided for each real name object, the alias held by another computer system for the real name object in the alias management book, and predetermined information on the location of the alias object having each alias. And shall be the management book to be registered.

When the alias object is newly created, deleted or changed in the computer system (processing step 1),
The registration information related to the alias object is sent to the computer system that holds the corresponding real name object (processing step 2), and registration, deletion, and change of the registration related to the alias object in the alias management list are performed ( Process step 3).

In the computer system, when the real name object is deleted and the real name is changed (processing step 4), all the registered real names are referenced by referring to the alias management list of the real name object. Regarding the alias, the computer system that holds the alias object of each alias is notified of the information regarding the deletion and change (processing step 5) to delete the corresponding alias object and update the alias object. (Processing step 6).

[0014]

According to the processing method of the present invention, when the real name object and the objects having the relationship between the real name object and the alias object are automatically notified and maintained of the new object, deletion or modification of the other object, etc. The normal relationship is always maintained, and when the real name object is deleted or the real name is changed, the alias object does not remain in the invalid state.

[0015]

EXAMPLE FIG. 3 shows an example of a structure of an alias management book of the present invention. Registration information for each alias object provided in a real name object and notified to the real name object is registered in each row.

In each line of the alias management list, an alias is recorded in the name column, the system name of the computer system having the alias object is recorded in the system column, and the system address of the alias object is recorded in the address column.

FIG. 4 is a diagram showing a detailed example of processing by the management subsystem of each computer system according to the present invention by taking the real name object "D" and the alias object "O" of the system B in FIG. 2 as an example. .

When a new program for the alias object "O" for the real name object "D" is issued from an appropriate program in the system A, the management subsystem receives the new request for the process A1 and creates the alias object "O" in the system A. to add.

In the process A2, a request for registering the alias object "O" in the alias management list of the real name object "D" in the system B is generated and transmitted by the information in the added alias object "O". In system B, registration is performed in process B1 and the results are notified to the request source.

When the system B issues a request to change the real name of the real name object "D" to "X" or to delete the object, the management subsystem receives and executes the request in process B2, and process B3. Refers to the alias management book of the real name object “D”.

Since the alias object "O" is registered in the alias management list, the management subsystem generates a request for changing the alias object "O" to the system A in step B4 according to the registered contents of the alias management list. Send.

Then, the management subsystem of the system A performs the following process in the process A3 according to the notified change contents. That is, when the name of the real name object “D” is changed to “X”, the real name information held by the alias object “O” is updated.

When the real name object "D" is deleted, the alias object "O" is deleted. System A
Then, when a request is made to change the name of the alias object "O", delete the object, or change the real name object corresponding to the alias object "O" (change the real name object from "D" to "Z" etc.), The request is executed in process A4.

According to the real name object information held in the alias object "O" in the process A5, a change request is generated and sent to the real name object "D" of the system B, for example.

In the change request, when the name of the alias object "O" is changed, the registered content of the name in the alias management list is changed. In the case of deleting the alias object and changing the corresponding real name object, the request is to delete the item with the name “O” registered from the alias management list.

When the corresponding real name object is changed, a registration request to the alias management list is generated for the newly corresponding real name object "Z" (which may not be system B) in process A6. And send.

[0027]

As is apparent from the above description, according to the present invention, in object management in a computer system network, the matching relationship between the real name object and the alias object is managed so as to be automatically maintained. There is a remarkable industrial effect.
