Abstract

A client connected to a communication network performs an access request to an object. An application server performs an application by an actual object according to the client request. An object pool connected to the client and the application server pools a proxy object corresponding to the actual object and holds the actual object management information. The application server notifies the object pool of an event according to the status change of the application. The object pool automatically updates the actual object management information according to the notification of the event from the application server.

Claims

1. An object pool data processing system using distributed objects, comprising:

a computer comprising memory and at least one processor;

an application server executing in the memory by the processor of the computer and hosting an application;

an object pool established in the memory by the application server, the object pool comprising a multiplicity of object proxies to objects of the application;

a client request analyzing unit disposed in the object pool and executing in the memory by the processor for analyzing an access request by a client to an object amongst the objects of the application;

an object information storage unit executing in the memory by the processor for storing object information at a termination of a process of said object pool;

an object creating unit disposed in the object pool executing in the memory by a processor for creating an object at a starting of a process of said object pool according to said object information stored by said object information storage unit; and

an object managing unit disposed in the object pool and executing in the memory by a processor for pooling the object in the object pool created by said object creating unit before accessing said object from said client;

said application server notifying said object managing unit of an event according to a change in status of said application, and said object managing unit automatically updating said object management information according to the notification of said event from said application server.

2. The object pool data processing system as set forth in claim 1, wherein the object information stored by said object information storage unit is constructed so that it can be at least recognized to be a last accessed object, and said object creating unit starting creation of said object from said last accessed object.
