Abstract

The invention relates to a data processing method comprising: receiving an attribute request from a device management client by a server using a first access protocol, wherein the attribute request comprises a first representation of an attribute of an element of a data processing system; mapping the attribute request from the first representation into a second representation, the second representation being an object-oriented standard representation comprising: objects, types of objects, collection of objects and attributes of objects, wherein the objects represent a set of elements; fetching the attribute from a cache coupled to the server, if the cache stores the attribute of the element; transforming the attribute request from the first protocol into a second protocol, if the attribute is not stored in the cache; fetching from a device management provider coupled to the element a plurality of attributes including the attribute using the second protocol, if the attribute is not stored in the cache; storing the plurality of attributes including the attribute in the cache with the object-oriented standard representation and sending the attribute to the device management client.

Claims

1. A data processing method comprising:

receiving an attribute request from a device management client by a server using a first access protocol, wherein said attribute request comprises a first representation of an attribute of an element of a data processing system;

mapping said attribute request from said first representation into a second representation, said second representation being an object-oriented standard representation comprising;

objects, types of objects, collection of objects and attributes of objects, wherein said objects represent a set of elements;

fetching said attribute from a cache coupled to said server, if said cache stores said attribute of said element;

transforming said attribute request from said first protocol into a second protocol, if said attribute is not stored in said cache;

fetching from a device management provider coupled to said element a plurality of attributes including said attribute using said second protocol, if said attribute is not stored in said cache;

storing said plurality of attributes including said attribute in said cache with said object-oriented standard representation and sending said attribute to said device management client.

2. The method of claim 1, wherein said attribute request further comprises a cache parameter, wherein said fetching to said cache is completed if said cache parameter is activated, wherein said fetching to said cache is disabled, if said cache parameter is deactivated.

3. The method as in claim 1, wherein the method further comprises:

identifying a first device management provider of said set of providers, wherein said first provider is coupled to said element; and

fetching disabled cache instruction of said first provider.

4. The method as in claim 3, wherein said fetching to said cache is completed, if said disabled cache instructions of said first provider is a periodic refresh with a time interval and if said information on said cache was received from said first provider within said time interval

5. The method as in claim 3, wherein the method further comprises:

checking if said information stored in said first provider has been changed, storing said changes in said cache and completing said fetching to said cache, if said disabled cache instructions is a check immediate.

6. The method as in claim 3, wherein if said disabled cache instruction is an asynchronous update, said information on said cache is updated using an asynchronous mechanism.

7. The method as in claim 1, wherein said first access protocol is an access protocol and is one of:

Common Information Model—

XML, Web Services for Management, or Web Services Distributed Management.

8. The method as in claim 1, wherein said information is stored on said cache is structured into Common Information Model classes, namespaces, class names and instances.

9. The method as in claim 1, wherein said server is a Common Information Model object manager server, wherein the method further comprises:

fetching all available information on said first provider and storing it in said cache, if said information of said element is not stored in said cache.

10. The method as in claim 1, wherein fetching all available information is completed with an enumerateInstances operation.

14. A computer program product stored on a computer usable medium, comprising computer readable program means for causing a computer to perform a method according to claim 1 when said program is run on said computer.

11. A device management server comprising:

a first adapter adapted for receiving attribute requests from a device management client by a server using a first access protocol with a first representation and mapping said attribute request from said first representation into an object-oriented standard representation, wherein said attribute request specifies an attribute of an element of a data processing system, wherein said object-oriented representation includes;

objects, types of objects, collection of objects and attributes of objects, wherein said objects represent said set of elements,

a core service adapted for fetching said attribute from a cache coupled to said server, wherein said cache is adapted for storing information describing a plurality of attributes of said set of elements, wherein said information is stored in said cache with said object-oriented standard representation,

a second adapter for transforming said attribute request from said first protocol into a second protocol and fetching a plurality of attributes including said attribute from a device management provider coupled to said element using said second protocol, if said instance is not stored in said cache.

12. A device management server as in claim 11, wherein said cache is further adapted for storing all available information from said device management provider, if said information of said element is not stored in said cache.

13. A device management server as in claim 11, wherein said device management server is a Common Information Model object manager server.
