Abstract

An event management system that plays a central role in handling varying loads of metadata events from each of a large number of touch-points or data servers that come into a Data Centric computing environment. As a matter of distinction when compared to conventional method-centric computing environments, there is broadly contemplated herein the concept not of physically installing a software agent on a designated system as stationary entity, but of launching it in a distributed computing environment and permitting it to “roam” around the numerous data servers to ensure consistency, accuracy and currency between the data entities managed by multiple data servers and the metadata servers in a data-centric computing environment.

Claims

1. A method of communicating metadata, the method comprising:

receiving, at a first node, a first mobile software agent capable of autonomously moving between event generating nodes;

obtaining, by the first mobile software agent, information regarding an event at the node;

creating a second mobile software agent and populating the second mobile software agent with the obtained information; and

sending the second mobile software agent populated with the obtained information to a second node.

2. The method according to claim 1, wherein the second mobile software agent is an instance of the first mobile software agent and is created by the first mobile software agent.

3. The method according to claim 1, wherein the obtained information is metadata corresponding to the event at the first node and the second node is a metadata server.

4. The method according to claim 1, wherein the first mobile software agent is not installed on the first node.

5. The method according to claim 3, wherein the first mobile software agent is dynamically provisioned to the first node by the second node in response to the first node generating the event.

6. The method according to claim 1, wherein the nodes comprise data servers;

and the event comprises a data event associated with one of the data servers.

7. The method according to claim 1, wherein the second mobile software agent comprises an itinerary, which is populated with a metadata server address relating to the first node associated with the event.

8. The method according to claim 3, wherein the second mobile software agent comprises a metadata component and the metadata component is populated with the metadata corresponding to the event at the first node prior to sending the second mobile software agent to the metadata server.

24. The method according to claim 1, wherein the second mobile software agent comprises a metadata component that includes metadata corresponding to the event at the first node, an itinerary component that includes an address of a metadata server, and a credential component that includes authentication information for authorizing the second mobile software agent to the metadata server.

9. An apparatus, implemented using a processor, comprising:

an interface which connects with a plurality of nodes in a computing environment; and

a mobile software component which acts to;

ascertain an event among the nodes; and

create a first mobile software agent and provision the first mobile software agent to a first node from among the nodes that generated the event,

wherein the first mobile software agent is configured to;

obtain formation regarding the event at the first node;

create a second mobile software agent and populate the second mobile software agent with the obtained information; and

send the second mobile software agent populated with the obtained information to a second node.

10. The apparatus according to claim 9, wherein the second mobile software agent is an instance of the first mobile software agent.

11. The apparatus according to claim 9, wherein the obtained information is metadata corresponding to the event at the first node and the second node is a metadata server.

12. The apparatus according to claim 9, wherein the first mobile software agent is configured so as not to install on the first node.

13. The apparatus according to claim 11, wherein the first mobile software agent is dynamically provisioned to the first node by the second node in response to the first node generating the event.

14. The apparatus according to claim 9, wherein the nodes comprise data servers;

and the event comprises a data event associated with one of the data servers.

15. The apparatus according to claim 9, wherein the second mobile software agent comprises an itinerary, which is populated with a metadata server address relating to the first node associated with the event.

16. The apparatus according to claim 11, wherein the second mobile software agent comprises a metadata component and the metadata component is populated with the metadata corresponding to the event at the first node prior to sending the second mobile software agent to the metadata server.

25. The apparatus according to claim 9, wherein the second mobile software agent comprises a metadata component that includes metadata corresponding to the event at the first node, an itinerary component that includes an address of a metadata server, and a credential component that includes authentication information for authorizing the second mobile software agent to the metadata server.

17. A non-transitory computer-readable storage medium readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method comprising:

receiving, at a first node, a first mobile software agent capable of autonomously moving between event generating nodes;

obtaining, by the first mobile software agent, information regarding an event at the node;

creating a second mobile software agent and populating the second mobile software agent with the obtained information; and

sending the second mobile software agent populated with the obtained information to a second node.

18. The non-transitory computer-readable storage medium according to claim 17, wherein the second mobile software agent is an instance of the first mobile software agent and is created by the first mobile software agent.

19. The non-transitory computer-readable storage medium according to claim 17, wherein the obtained information is metadata corresponding to the event at the first node and the second node is a metadata server.

20. The non-transitory computer-readable storage medium according to claim 17, wherein the first mobile software agent is not installed on the first node.

21. The non-transitory computer-readable storage medium according to claim 19, wherein the first mobile software agent is dynamically provisioned to the first node by the second node in response to the first node generating the event.

22. The non-transitory computer-readable storage medium according to claim 17, wherein the nodes comprise data servers;

and the event comprises a data event associated with one of the data servers.

23. The non-transitory computer-readable storage medium according to claim 19, wherein the second mobile software agent comprises an itinerary, which is populated with a metadata server address relating to the first node associated with the event, and

the second mobile software agent further comprises a metadata component and the metadata component is populated with the metadata corresponding to the event at the first node prior to sending the second mobile software agent to the metadata server.

26. The non-transitory computer-readable storage medium according to claim 17, wherein the second mobile software agent comprises a metadata component that includes metadata corresponding to the event at the first node, an itinerary component that includes an address of a metadata server, and a credential component that includes authentication information for authorizing the second mobile software agent to the Metadata Server.
