Abstract

A system for providing real-time cluster configuration data within a clustered computer network including a plurality of clusters, including a primary node in each cluster wherein the primary node includes a primary repository manager, a secondary node in each cluster wherein the secondary node includes a secondary repository manager, and wherein the secondary repository manager cooperates with the primary repository manager to maintain information at the secondary node consistent with information maintained at the primary node.

Claims

1. A system for providing real-time cluster configuration data within a clustered computer network comprising a plurality of clusters, comprising:

a primary node in each cluster wherein said primary node includes a primary repository manager;

a secondary node in each cluster wherein said secondary node includes a secondary repository manager; and

wherein said secondary repository manager cooperates with said primary repository manager to maintain information at said secondary node consistent with information maintained at said primary node.

2. The system of

claim 1

, wherein said primary node further comprises a primary data repository and primary services.

3. The system of

claim 2

, wherein said secondary node further comprises a secondary data repository and secondary services.

4. The system of

claim 1

, further comprising:

at least one additional node in at least one cluster wherein said additional node includes a repository agent.

5. The system of

claim 4

, wherein said repository agent forwards all write/update requests to said primary repository manager.

6. The system of

claim 4

, wherein said repository agent includes a software cache of repository data, wherein said repository data may be quickly accessed by an application.

7. The system of

claim 1

, wherein said primary repository manager manages the storage of repository data on a first computer-readable medium, the maintenance of repository data on memory, and the synchronization of repository updates.

8. The system of

claim 7

wherein said secondary repository manager manages the storage of repository data on a second computer-readable medium, and the maintenance of repository data on memory.

9. The system of

claim 8

wherein the repository data in said secondary node is synchronously up-dated so as to remain consistent with the repository data of said first node.

10. The system of

claim 8

wherein said first and second computer-readable mediums each include a disc.

11. A method of providing real-time cluster configuration data within a clustered computer network comprising a plurality of clusters, comprising the steps of:

choosing a primary node in each cluster wherein said primary node includes a primary repository manager;

choosing a secondary node in each cluster wherein said secondary node includes a secondary repository manager; and

causing said secondary repository manager to cooperate with said primary repository manager to maintain information at said secondary node consistent with information maintained at said primary node.

12. The method of

claim 11

, comprising the further step of:

providing a repository agent for each additional mode of each cluster, wherein the repository agent interfaces with the primary repository manager in its cluster.

13. The method of

claim 11

, comprising the further steps of:

sending write/update information from a client only to said primary repository manager;

causing said write/update information to be written in said primary repository manager and said secondary repository manager; and

validating completion of the entry of said write/update information only when the information successfully is written in both said primary repository manager and said secondary repository manager.

14. A computer program product comprising a computer useable medium having computer readable code embodied therein for providing real-time cluster configuration data within a clustered computer network comprising a plurality of clusters, the computer program product adapted when run on a computer to effect steps including:

choosing a primary node in each cluster wherein said primary node includes a primary repository manager;

choosing a secondary node in each cluster wherein said secondary node includes a secondary repository manager; and

causing said secondary repository manager to cooperate with said primary repository manager to maintain information at said secondary node consistent with information maintained at said primary node.

15. The computer program product of

claim 14

, wherein the computer program product is adapted when run or a computer to effect the further steps of:

providing a repository agent for each additional node of each cluster, wherein the repository agent interfaces with the primary repository manager in its cluster.

16. The computer program product of

claim 14

, comprising the further steps of:

sending write/update information from a client only to said primary repository manager;

causing said write/update information to be written in said primary repository manager and said secondary repository manager; and

validating completion of the entry of said write/update information only when the information successfully is written in both said primary repository manager and said secondary repository manager.

17. A computer program product comprising a computer useable medium having computer readable code embodied therein for providing real-time cluster configuration data within a clustered computer network comprising a plurality of clusters, the computer program product comprising:

means for choosing a primary node in each cluster wherein said primary node includes a primary repository manager;

means for choosing a secondary node in each cluster wherein said secondary node includes a secondary repository manager; and

means for causing said secondary repository manager to cooperate with said primary repository manager to maintain information at said secondary node consistent with information maintained at said primary node.

18. The computer program product of

claim 17

, further comprising:

means for providing a repository agent for each additional mode of each cluster, wherein the repository agent interfaces with the primary repository manager in its cluster.

19. The computer program product of

claim 17

, further comprising:

means for sending write/update information from a client only to said primary repository manager;

means for causing said write/update information to be written in said primary repository manager and said secondary repository manager; and

means for validating completion of the entry of said write/update information only when the information successfully is written in both said primary repository manager and said secondary repository manager.
