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. A client server system using distributed objects, comprising:

a client connected to a communication network for performing an access request to an object;

an application server for performing an application by an actual object according to the access request by said client; and

an object pool server connected to said client through said communication network and connected to said application server for pooling a proxy object corresponding to said actual object and for holding actual object management information that is information on said actual object, wherein said application server notifies said object pool server of an event according to a change in status of said application, and said object pool server automatically updates said actual object management information according to the notification of said event from said application server.

2. The client server system as set forth in claim 1, wherein the event notified from said application server is formed according to at least one of a result of a process of starting a project and a result of a process of stopping the project.

3. An object pool using distributed objects, comprising:

a client request analyzing unit for analyzing an access request to an object;

an object information storage unit for storing object information at a termination process of said object pool;

an object creating unit for creating an object at a starting process of said object pool according to said object information stored by said object information storage unit; and

an object managing unit for pooling the object created by said object creating unit before accessing said object from said client.

4. The object pool as set forth in claim 3, 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 starts creation from said last accessed object.

5. A client server system using distributed objects, comprising:

an object pool connected through a communication network to a client which sends an access request to an object, and for pooling objects and managing object information; and

an application execution environment connected to said object pool for executing an application according to the access request of said client, and notifying said object pool of an event according to a status change of said application, wherein said object pool updates said object information according to the event notification from said application execution environment.

6. The client server system as set forth in claim 5, wherein an object pool server having a function of said object pool and an application server in said application execution environment are connected to each other through a network, said object pool server pooling objects as proxy objects.

7. The client server system as set forth in claim 5, wherein said object pool and said application execution environment are formed on the same server.

8-10. -10. (canceled)

11. A storage medium in which a program to be executed by a computer is stored so that it can be read by an input unit of said computer, wherein said program makes said computer execute:

a monitoring process for monitoring execution status of a project which executes an application utilizing distributed objects;

an event creating process for creating an event according to execution status of the project monitored by said monitoring process; and

an event issuing process for issuing the event created by said event creating process to an object pool server connected through a network or the like.

12. A storage medium in which a program to be executed by a computer is stored so that it can be read by an input unit of said computer, said computer being connected through a network or the like to an application server for executing an application utilizing distributed objects, and to a client which requests the execution of said application, wherein said program makes said computer execute:

an object pooling process for pooling proxy objects corresponding to actual objects to be executed by said application server; and

an updating process for receiving an event issued from said application server, and updating management information on said actual objects according to said event.

13. The storage medium as set forth in claim 12, wherein said computer is made to further execute:

an execution status managing process for keeping track of execution statuses of said objects, and managing them for each object;

a request analyzing process for analyzing a request including an object creation request and/or an object deletion request from said client; and

a process for executing, upon receipt of a result of a request analysis by said request analyzing process, creation of an object and/or the deletion of an object according to a management result by said execution status managing process.

14. A program sending apparatus, comprising:

a storage unit for storing a software product which makes a computer execute an event forming program for forming an event according to a change in status of an application utilizing distributed objects, and an object pooling program for pooling objects according to the event formed by said event forming process; and

a sending unit for reading out said program from said storage unit, and sending said software product.

15. A program sending apparatus, comprising:

a storage unit for storing a program which makes a computer execute an object pooling process for pooling, on a server, objects associated with execution of an application utilizing distributed objects, an information storing process for storing object information in said server, and a creation sequence determining process for determining a sequence of objects to be created according to said object information stored by said information storing process; and

a sending unit for reading out said program from said storage unit, and sending said program.
