Abstract

A computer system includes at least one client computer and at least one server computer. An Object Configuration Manager allows a user to distribute and use objects, such as business logic, database tables, and batch applications. Additionally, through the Object Configuration Manager, access to objects can be limited to select users and applications. The Object Configuration Manager is implemented as a software application.

Claims

1. A method for managing the configuration of distributed objects in a computer network having a plurality of nodes, the method comprising:

maintaining object configuration information on the nodes, said object configuration information defining object accessibility and object locations;

receiving a request to perform an action with respect to one of the objects;

determining whether the action may affect a set of the nodes including affecting an ability of said set of nodes to access the one object or affecting a location at which said set of nodes accesses the one object;

in response to determining that the action may affect said set of nodes, notifying said set of affected nodes with a notification message indicating changes to be made to said object configuration information resulting from the action;

changing said object configuration information maintained on said set of affected nodes for the one object in accordance with said notification message; and

performing the action with respect to the one object;

wherein said object configuration information is updated dynamically at said set of affected nodes to reconfigure the one object in the computer network.

2. The method of claim 1, wherein the object is a batch application.

3. The method of claim 1, wherein the object is a database table.

4. The method of claim 1, wherein the object is business logic.

5. The method of claim 1, wherein performing the action comprises running a batch application.

6. The method of claim 1, wherein performing the action comprises making a copy of a batch application at one node of said set of affected nodes and sending the copy to another node of said set of affected nodes in the computer network.

7. The method of claim 1, wherein performing the action comprises deleting a batch application.

8. The method of claim 1, wherein performing the action comprises the step of altering a database entry indicating a location in the computer network where a batch application can be located.

9. The method of claim 1, wherein performing the action comprises the step of making a copy of a database table at one node of aid set of affected nodes and sending the copy to another node of said set of affected nodes in the computer system.

10. The method of claim 1, wherein performing the action comprises the step of deleting a database table.

11. The method of claim 1, wherein performing the action comprises the step of altering a database entry indicating a location in the computer system where a database table can be located.

12. The method of claim 1, wherein the determining step includes determining whether the action affects the ability of a user or application associated with another node to access the object.

13. The method of claim 1 further comprising:

packaging said request at a requesting one of said set of affected nodes;

receiving said packaged request at a processing one of said set of affected nodes;

determining at the processing node an appropriate middleware component from a group of middleware components including a business logic middleware component, a batch application middleware component and a database middleware component for performing the action;

sending the packaged request to the determined appropriate middleware component for performing the action; and

sending the results of performing the action from the processing node to the requesting node.

14. The method of claim 13, wherein the one object is a batch application object and the determined appropriate middleware component is said batch application middleware component.

15. The method of claim 13, wherein the one object is a business logic object and the determined appropriate middleware component in said business logic middleware component.

16. The method of claim 13, wherein the one object is a database object and the determined appropriate middleware component is said database middleware component.

17. A computer program embodied in a tangible medium and capable of being read by a computer for performing the method of claim 13.

18. A method according to claim 1, further including maintaining said object configuration information on a management database, and supplying said object configuration information to the nodes from said management database.

19. A method according to claim 18, further including updating said object configuration information maintained on said management database to correspond to said changed object configuration information.

20. A computer program embodied in a tangible medium and capable of being read by a computer for performing the method of claim 1.

21. A computer system for managing the configuration of distributed objects in the computer system, the computer system comprising:

a network including a plurality of nodes;

said nodes including an object locator for maintaining object configuration information defining object accessibility and object locations;

an application for receiving a request to perform an action with respect to one of the objects;

the application determining whether the action may affect a set of the nodes including affecting an ability of said set of nodes to access the one object or affecting a location at which said set of nodes accesses the one object and, in response to determining that the action may affect said set of nodes, notifying said set of affected nodes with a notification message indicating changes to be made to said object configuration information resulting from the action to cause said object configuration information maintained on said set of affected nodes for the one object to be changed in accordance with said notification message; and

middleware means for performing the action with respect to the one object in response to receiving the request;

said object configuration information is updated dynamically at said affected nodes to reconfigure the one object in the computer network.

22. The computer system of claim 21, wherein the object is a batch application.

23. The computer system of claim 21, wherein the object is business logic.

24. The computer system of claim 21, wherein the object is a database table.
