Abstract

A compiler converts managed object format code or common information model extensible markup language code to instances that can be implemented by management extension models such as Java Management Extension MBeans. The instances which are generated by the compiler interface work together with a meta-model service that exposes the semantics of each object within the common information model to the run-time environment through a parallel managed extension model interface. This meta-model also introspects the common information model so as to provide a query service by forming associations between objects of the common information model and instances of the management extension model.

Claims

1. A computer implemented method for mapping a common information model to a management extension model independent of prior knowledge of the common information model, the method comprising:

converting objects from the common information model to instances capable of being implemented by the management extension model, wherein each object of the common information model comprises a specification and a schema;

generating a management extension interface based on the instances implemented using a set of common information model objects supported by the management extension model; and

creating from the common information model, a meta-model service of the objects exposing information regarding the objects to a run-time environment through a parallel managed extension model interface.

2. The computer implemented method of claim 1, wherein generating comprises forming an interface between the common information model and the management extension model such that, when possible, common information model types are mapped to Java standard types, and responsive to common information model types not being able to be mapped to Java standard types, common information types being mapped to open-data objects.

3. The computer implemented method of claim 1, wherein generating comprises forming an interface between the common information model and the management extension model such that each common information model property is mapped to a management extension model attribute.

4. The computer implemented method of claim 1, wherein generating comprises forming an interface between the common information model and the management extension model such that each common information model method is mapped to a management extension model method of an identical name.

5. The computer implemented method of claim 4, wherein information lost in the mapping of each common information model method to the management extension model method is preserved by a meta-model mapping.

6. The computer implemented method of claim 1, wherein generating comprises forming an interface between the common information model and the management extension model such that <

schema name>

_<

class name>

for the common information model class is equivalent to <

information model prefix>

.<

schema name>

.<

class name>

for the equivalent management extension model.

7. The computer implemented method of claim 1, wherein the common information model is presented in a common information model extended markup language format.

8. The computer implemented method of claim 1, wherein the common information model is presented in a common information model managed object format.

9. The computer implemented method of claim 8, wherein the meta model service introspects the managed object format of the common information model to provide a query service producing associations between objects of the common information model and instances of the management extension model

10. The computer implemented method of claim 1, wherein generating comprises forming an interface between the common information model and the management extension model such that each common information model object path is mapped to a management extension model object name.

11. The computer implemented method of claim 1, wherein the meta-model service provides to the management extension model attribute information about the common information model.

12. The computer implemented method of claim 1, wherein the meta-model service provides to the management extension model parent and child information about the common information model.

13. The computer implemented method of claim 1, wherein the management extension model is a Java management extension model, and wherein the meta-model service exposes a managed object format of the common information model to the Java management extension model providing common information model-derived class information to the Java management extension model.

14. The computer implemented method of claim 13, further comprising matching a Java management extension based query to the common information model meta-model.

15. The computer implemented method of claim 13, wherein generating comprises correlating each construct of a managed object format version of the common information model to a corresponding construct of the Java management extension model making common information model data available for examination in run-time.

16. A computer system for mapping a first information model to a second information model independent of prior knowledge of the first information model, the computer system comprising:

a software portion configured to convert objects from the first information model to instances capable of being implemented by the second information model, wherein each of the objects comprise a specification and a schema;

a software portion configured to generate a second information model interface based on the instances using a set of first information model objects supported by the second information model; and

a software portion configured to create from the first information model, a meta-model service of the objects exposing information regarding the objects to a run-time environment through a parallel model interface of the second information model, wherein the meta-model service provides to the second information model parent and child information about the first information model.

17. A computer system for mapping a common information model to a management extension model independent of prior knowledge of the common information model, the system comprising:

a software portion configured to convert objects from the common information model to instances capable of being implemented by the management extension model, wherein each of the objects comprises a specification and a schema;

a software portion configured to generate a management extension interface based on the instances using a set of common information model objects supported by the management extension model; and

a software portion configured to create from the common information model, a meta-model service of the objects exposing information regarding the objects to a run-time environment through a parallel managed extension model interface, wherein the meta-model introspects the common information model to provide a query service producing associations between objects of the common information model and instances of the management extension model.

18. The computer system of claim 17, wherein the management extension model is a Java management extension model, and wherein the meta-model service exposes a managed object format of the common information model to the Java management extension model providing common information model-derived class information to the Java management extension model.

19. The computer system of claim 17, further comprising a software portion configured to match a Java management extension based query to the common information model meta-model.

20. The computer system of claim 17, wherein the software portion configured to generate comprises a software portion to correlate each construct of a managed object format version of the common information model to a corresponding construct of the Java management extension model making common information model data available for examination in run-time.
