Abstract

Techniques for expressing temporal relationships between lifecycle representations are provided. For example, one computer-implemented technique includes obtaining two or more lifecycle representations of at least two components of at least one computing system, annotating the two or more lifecycle representations with at least one temporal relationship, and storing the two or more annotated lifecycle representations as at least one deployment descriptor, wherein the at least one deployment descriptor is useable for managing the at least one computing system. In another computer-implemented technique, at least two internal lifecycle models of at least two components of at least one computing system are analyzed, at least one temporal relationship that exists between the at least two components are analyzed, and the at least one temporal relationship is transformed into at least one sequence of change management operations for use in managing the at least one computing system.

Claims

1. A computer-implemented method for expressing temporal relationships between lifecycle representations, the method comprising the steps of:

obtaining two or more lifecycle representations of at least two components of at least one computing system, wherein the at least two components comprise a first component and a second component, and wherein the two or more lifecycle representations comprise at least one of an arbitrary set of states and change management operations;

annotating the two or more lifecycle representations with at least one temporal relationship, wherein the at least one temporal relationship exists between two states in the lifecycle representations of the at least two components, wherein the at least one temporal relationship links a first state in the lifecycle representation of the first component with a second state in the lifecycle representation of the second component;

storing the two or more annotated lifecycle representations as at least one deployment descriptor, wherein the at least one deployment descriptor is useable for managing the at least one computing system; and

outputting the two or more annotated lifecycle representations as at least one partially ordered list of change management operations.

2. The method of claim 1, wherein the step of annotating the two or more lifecycle representations with at least one temporal relationship comprises traversing the at least one temporal relationship.

3. The method of claim 1, wherein the step of annotating the two or more lifecycle representations with at least one temporal relationship comprises generating at least one precedence constraint.

4. The method of claim 1, wherein the at least one deployment descriptor comprises information relating to hardware characteristics of a computing system.

5. The method of claim 1, wherein the at least one deployment descriptor comprises at least one of names, internet protocol (IP) addresses and symbolic names of at least one computing system.

6. The method of claim 1, wherein each component comprises at least one of software, hardware, middleware and networking components.

7. The method of claim 1, wherein the step of annotating the two or more lifecycle representations with at least one temporal relationship comprises establishing at least one pair-wise link between two or more lifecycle representations of two or more different managed resources.

8. The method of claim 1, wherein the at least one temporal relationship may be annotated with a precedence constraint.

9. The method of claim 1, wherein the at least two or more components are co-located on an identical hosting environment.

10. The method of claim 1, wherein the at least two or more components are located on different hosting environments.

11. The method of claim 1, wherein one component is a hosting environment for another component.

12. An apparatus for expressing temporal relationships between lifecycle representations, comprising:

a memory; and

at least one processor coupled to the memory and operative to;

obtain two or more lifecycle representations of at least two components of at least one computing system, wherein the at least two components comprise a first component and a second component, and wherein the two or more lifecycle representations comprise at least one of an arbitrary set of states and change management operations;

annotate the two or more lifecycle representations with at least one temporal relationship, wherein the at least one temporal relationship exists between two states in the lifecycle representations of the at least two components, wherein the at least one temporal relationship links a first state in the lifecycle representation of the first component with a second state in the lifecycle representation of the second component;

store the two or more annotated lifecycle representations as at least one deployment descriptor, wherein the at least one deployment descriptor is useable for managing the at least one computing system; and

output the two or more annotated lifecycle representations as at least one partially ordered list of change management operations.

13. The apparatus of claim 12, wherein each component comprises at least one of software, hardware, middleware and networking components.

14. The apparatus of claim 12, wherein the step of annotating the two or more lifecycle representations with at least one temporal relationship comprises establishing at least one pair-wise link between two or more lifecycle representations of two or more different managed resources.

15. A computer program product comprising a computer useable storage memory having computer useable program code for expressing temporal relationships between lifecycle representations, the computer program product including:

computer useable program code for obtaining two or more lifecycle representations of at least two components of at least one computing system, wherein the at least two components comprise a first component and a second component, and wherein the two or more lifecycle representations comprise at least one of an arbitrary set of states and change management operations;

computer useable program code for annotating the two or more lifecycle representations with at least one temporal relationship, wherein the at least one temporal relationship exists between two states in the lifecycle representations of the at least two components, wherein the at least one temporal relationship links a first state in the lifecycle representation of the first component with a second state in the lifecycle representation of the second component;

computer useable program code for storing the two or more annotated lifecycle representations as at least one deployment descriptor, wherein the at least one deployment descriptor is useable for managing the at least one computing system; and

computer useable program code for outputting the two or more annotated lifecycle representations as at least one partially ordered list of change management operations.

16. The computer program product of claim 15, wherein each component comprises at least one of software, hardware, middleware and networking components.

17. The computer program product of claim 15, wherein the step of annotating the two or more lifecycle representations with at least one temporal relationship comprises establishing at least one pair-wise link between two or more lifecycle representations of two or more different managed resources.
