Abstract

A distributed object management method and system, and a recording medium for recording a processing program of the method and the system are disclosed. According to this method, a server object can be changed in operation. The method for managing objects in a distributed object environment includes steps of requesting server object information of server objects to be accessed, selecting and supplying a requester with server object information of the newest one of requested server objects, accessing the server object indicated in the server object supplied, and performing processing requested by the access.

Claims

1. A distributed object management method for managing objects in a distributed object environment, comprising the steps of:

requesting, by a client object, server object information from a management object of server objects to be accessed;

selecting and supplying a requester with server object information of a newest server object of requested server objects based on a change information including a revision information showing a newness of each said requested server object, the selecting and supplying being performed by the management object;

accessing said newest server object indicated in the server object information supplied; and

performing processing requested by said access,

wherein a newest revision of the accessed server object, if it exists, is accessible in response to a request while the performing processing requested continues.

2. A distributed object management method according to claim 1, further comprising the steps of:

in a case where the requester is a server object to be accessed during said accessing step, selecting and supplying, to the requester, the server object information of another server object to be accessed from said server object, in accordance with said change information for the requester server object.

3. A distributed object management method according to claim 2, further comprising the steps of:

in a case where there are a plurality of server objects having a same server object name or same interface identification information, stopping server objects having old change information including old version information.

4. A distributed object management system for managing objects in a distributed object environment, comprising:

a server object information acquisition unit for requesting server object information of a server object to be accessed;

a server object information selection unit for selecting and supplying a requester with server object information of a newest server object of requested server objects based on a change information including revision information showing a newness of each said requested server objects;

a server object access unit for accessing a server object indicated in said server object information supplied; and

a request processing unit for performing processing requested by said access,

wherein a newest revision of the accessed server object, if it exists, is accessible in response to a request while the performing processing requested continues.

5. A computer readable recording medium having recorded thereon a program for causing a computer to function as a distributed object management system for managing objects in a distributed object environment, comprising:

a server object information acquisition unit for requesting server object information of server objects to be accessed;

a server object information select unit for selecting and supplying a requester with server object information of a newest server object of requested server objects based on a change information including revision information showing a newness of each said requested server objects;

a server object access unit for accessing a server object indicated in said server object information supplied; and

a request processing unit for performing processing requested by said access,

wherein a newest revision of the accessed server object, if it exists, is accessible in response to a request while the performing processing requested continues.
