Abstract

An architecture and method for managing at least two distinct machines (or objects) in which resources are shared as a single entity (or object) in an agent-based system. The agent-based system comprising a controller, a local agent coupled to the controller, and at least one clustered machine. The at least one clustered machine includes at least two individual agents, the at least two individual agents sharing at least one shared resource/service. The system also includes a virtual non-persistent connection for coupling the at least two individual agents to the local agent. The at least one shared resource/service is accessed by the local agent through the virtual non-persistent connection using a virtual IP address to enable the at least two individual agents of the at least one clustered machine to be represented as a single object.

Claims

1. A method for managing multiple objects as a single interface in an agent-based system, comprising:

generating a first set of commands to obtain one or more resource or service shared by an agent of a first machine and an agent of a second machine;

sending security information regarding a virtual non-persistent connection from a local agent of a controller through a persistent connection to the first machine and the second machine;

opening the virtual non-persistent connection using a single virtual IP address to both the first machine and the second machine from the local agent as the single interface;

sending the first set of commands from the local agent, through the virtual non-persistent connection to a clustered machine containing the first machine, the second machine and the shared one or more resource or service, wherein the shared one or more resource or service is accessible from the agent of one of the first machine and the second machine;

triggering the agent of one of the first machine and the second machine having access to the shared resource or service to process the first set of commands;

receiving information, through the virtual non-persistent connection, from the one of the first machine and the second machine as a result of the agent processing the first set of commands; and

closing the virtual non-persistent connection.

2. The method of claim 1, wherein prior to generating the first set of commands, the method further comprising:

receiving a request from a user to manipulate the one or more shared resource or service.

3. The method of claim 2, wherein a user comprises one of an administrator and a client.

4. The method of claim 1, wherein prior to generating the first set of commands, the method further comprising:

triggering a request to obtain the one or more shared resource or service.

5.

6. The method of claim 1, wherein sending the first set of commands through the virtual non-persistent connection to the first and second machine further comprises sending the first set of commands to the first and second machine using a virtual Internet Protocol (IP) address of a single object representing a first managed object and second managed object in which the one or more resource or service is shared.

7. The method of claim 1, wherein triggering the agent of an active one of the first and second machine having access to the one or more shared resource or service to process the first set of commands further comprises causing the agent to:

interpret the first set of commands;

perform functions required by the first set of commands; and

send information relating to the first set of commands back through the virtual non-persistent connection.

8. The method of claim 1, wherein prior to opening the virtual non-persistent connection, the method further comprises:

sending a security token through a persistent connection to a the agent of the first and second machine to identify the virtual non-persistent connection as a trusted connection from the local agent.

9. The method of claim 1, further comprising:

receiving a second request for an individual non-shared resource or service of the first machine, the first machine represented as one object generating a second set of commands for obtaining the requested non-shared resource or service from the first machine;

sending the second set of commands through a persistent connection to the first machine;

triggering the agent on the first or second machine to process the second set of commands; and

receiving information from the agent of the first machine through the persistent connection as a result of the agent processing the second set of commands.

10. The method of claim 9, wherein triggering the remote agent of the first machine to process the second set of commands further comprises causing the agent to:

interpret the second set of commands;

perform functions required by the second set of commands; and

send information relating to the second set of commands back through the persistent connection.

11. The method of claim 9, farther comprising sending the received information to the user.

12. The method of claim 1, further comprising:

initiating a second request for individual non-shared resource or service of the first machine, the first machine represented as one object;

generating a second set of commands for obtaining the requested non-shared resource or service from the first machine;

sending the second set of commands through a persistent connection to the first machine;

triggering the agent on the first machine to process the second set of commands; and

receiving information from the agent of the first machine through the persistent connection as a result of the agent processing the second set of commands.

13. The method of claim 12, wherein triggering the agent of the first machine to process the second set of commands further comprises causing the agent to:

interpret the second set of commands;

perform necessary functions required by the second set of commands; and

send information relating to the second set of commands back through the persistent connection.

14. An article comprising:

a computer storage medium having a plurality of machine accessible instructions, which when executed by a processor implement;

generating a first set of commands to obtain one or more resource or service shared by an agent of a first machine and an agent of a second machine;

sending security information regarding a virtual non-persistent connection from a local agent of a controller through a persistent connection to the first machine and the second machine;

opening the virtual non-persistent connection using a single virtual IP address to both the first machine and the second machine from the local agent as the single interface;

sending the first set of commands from the local agent, through the virtual non-persistent connection to a clustered machine containing the first machine, the second machine and the shared one or more resource or service, wherein the shared one or more resource or service is accessible from the agent of one of the first machine and the second machine;

triggering the agent of one of the first machine and the second machine having access to the shared resource or service to process the first set of commands;

receiving information, through the virtual non-persistent connection, from the one of the first machine and the second machine as a result of the agent processing the first set of commands; and

closing the virtual non-persistent connection.

15. The article of claim 14, further comprising instructions for:

receiving a request from a user to manipulate the one or more shared resource or service.
