Abstract

A Redundancy Group includes one or more functionally equivalent resources, and is employed in the dynamic reconfiguration of resources. This enables a business application associated with the resources to be actively managed during runtime.

Claims

1. A computer-implemented method to determine targets for operations, said computer-implemented method comprising:

obtaining a redundancy group, said redundancy group comprising one or more functionally equivalent resources of a particular type; and

dynamically evaluating, during runtime and in response to an occurrence of an event, which resource of a plurality of resources of the redundancy group is to be used as a target for an operation to be performed.

2. The computer-implemented method of claim 1, wherein the dynamically evaluating takes into consideration the event that has occurred and a state of an Information Technology (IT) runtime environment of which the redundancy group is included.

3. The computer-implemented method of claim 2, wherein the dynamically evaluating further takes into consideration one or more requirements for co-location or anti-co-location in selecting the target resource.

4. The computer-implemented method of claim 1, wherein the redundancy group has a state associated therewith, said state used to influence the availability of an Information Technology runtime environment of which the redundancy group is included.

5. The computer-implemented method of claim 1, wherein the dynamically evaluating selects multiple resources of the redundancy group to be used as targets for multiple operations to be performed, wherein the dynamically evaluating optimizes the selection such that there is a target for each operation of the multiple operations.

6. The computer-implemented method of claim 5, wherein the resource capable of accommodating a minimum number of operations is selected prior to the resource capable of accommodating more than the minimum number of operations.

7. The computer-implemented method of claim 5, wherein the dynamically evaluating is based on at least one of resources in a repel list, non-operational resources, already started resources, co-location requirements or anti-co-location requirements.

8. The computer-implemented method of claim 1, wherein the dynamically evaluating is based on quality of service characteristics of the resources of the redundancy group.

9. A system to determine targets for operations, said system comprising:

a memory comprising a redundancy group, said redundancy group comprising one or more functionally equivalent resources of a particular type; and

at least one processor coupled to the memory to dynamically evaluate, during runtime and in response to an occurrence of an event, which resource of a plurality of resources of the redundancy group is to be used as a target for an operation to be performed.

10. The system of claim 9, wherein the at least one processor to dynamically evaluate takes into consideration the event that has occurred and a state of an Information Technology runtime environment of which the redundancy group is included.

11. The system of claim 9, wherein the redundancy group has a state associated therewith, said state used to influence the availability of an Information Technology runtime environment of which the redundancy group is included.

12. The system of claim 9, wherein the at least one processor to dynamically evaluate selects multiple resources of the redundancy group to be used as targets for multiple operations to be performed, wherein the dynamically evaluating optimizes the selection such that there is a target for each operation of the multiple operations.

13. The system of claim 12, wherein the resource capable of accommodating a minimum number of operations is selected prior to the resource capable of accommodating more than the minimum number of operations.

14. The system of claim 9, wherein the dynamically evaluating is based on quality of service characteristics of the resources of the redundancy group.

15. An article of manufacture comprising:

at least one computer usable medium having computer readable program code logic to determine targets for operations, said computer readable program code logic when executing performing the following;

obtaining a redundancy group, said redundancy group comprising one or more functionally equivalent resources of a particular type; and

dynamically evaluating, during runtime and in response to an occurrence of an event, which resource of a plurality of resources of the redundancy group is to be used as a target for an operation to be performed.

16. The article of manufacture of claim 15, wherein the dynamically evaluating takes into consideration the event that has occurred and a state of an Information Technology runtime environment of which the redundancy group is included.

17. The article of manufacture of claim 16, wherein the dynamically evaluating further takes into consideration one or more requirements for co-location or anti-co-location in selecting the target resource.

18. The article of manufacture of claim 15, wherein the redundancy group has a state associated therewith, said state used to influence the availability of an Information Technology runtime environment of which the redundancy group is included.

19. The article of manufacture of claim 15, wherein the dynamically evaluating selects multiple resources of the redundancy group to be used as targets for multiple operations to be performed, wherein the dynamically evaluating optimizes the selection such that there is a target for each operation of the multiple operations.

20. The article of manufacture of claim 15, wherein the dynamically evaluating is based on quality of service characteristics of the resources of the redundancy group.
