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 pooling method for pooling objects in advance on a specified server to execute an application in a distributed system, said object pooling method comprising the steps of:

storing object information when a process of said server is terminated; and

creating objects according to said object information when a process of said server is started; and

pooling the created objects.

2. The object pooling method of claim 1, wherein said object information is stored with a predetermined priority, and said objects are created in descending order with respect to said priority.

3. An object pooling method on an object pool which is connected through a communication network to a client which sends an access request to an object, and is connected to an application execution environment in which an actual object is executed, comprising the steps of:

pooling a proxy object corresponding to an actual object in said application execution environment;

recognizing a change in status of the actual object in said application execution environment; and

updating actual object management information according to said recognized status change.
