Abstract

Embodiments of the present invention address deficiencies of the art in respect to configuration changes in a network architecture and provide a method, system and computer program product for change verification using a configuration management database (CMDB). In one embodiment of the invention, a change verification method can be provided. The method can include receiving a proposed configuration change for application to a CMDB, cloning at least a portion of the CMDB to produce a clone, applying the proposed configuration change to the clone, and evaluating the clone as modified by the proposed configuration change. Thereafter, the proposed configuration change can be applied to a resource referenced by the clone based upon the evaluation.

Claims

1. A change verification method comprising:

receiving a proposed configuration change for application to a configuration management database (CMDB);

cloning at least a portion of the CMDB to produce a clone;

applying the proposed configuration change to the clone; and

,

evaluating the clone as modified by the proposed configuration change.

2. The method of claim 1, further comprising proceeding to apply the proposed configuration change to a corresponding resource referenced by the clone based upon the evaluation

3. The method of claim 1, wherein cloning at least a portion of the CMDB to produce a clone, comprises cloning the entire CMDB to produce a clone.

4. The method of claim 1, wherein evaluating the clone as modified by the proposed configuration change, comprises:

loading a set of configuration rules;

evaluating data in the clone according to the set of configuration rules; and

,

identifying any violations of the configuration rules in the set.

5. The method of claim 4, further comprising:

reporting the violations through a user interface; and

,

permitting an application of the proposed configuration change to a resource referenced in the CMDB responsive to an affirmative approval provided through the user interface.

6. A configuration management database (CMDB) managed data processing system configured for change verification comprising:

a plurality of host computing systems hosting a plurality of applications;

a change management host coupled to the host computing systems over a computer communications network;

a CMDB coupled to the change management host; and

,

change verification logic coupled to the change management host, the change verification logic comprising program code enabled to receive a proposed configuration change for application to the CMDB, clone at least a portion of the CMDB to produce a clone, apply the proposed configuration change to a corresponding resource referenced by the clone, evaluate the clone as modified by the proposed configuration change, and apply the proposed configuration change to the CMDB based upon the evaluation.

7. The system of claim 6, further comprising a set of configuration rules, the change verification logic comprising additional program code enabled to compare the clone as modified to the set of configuration rules, and to identify any violations of the configuration rules in the set.

8. The system of claim 7, wherein the set of configuration rules comprise rules specifying acceptable levels of firmware parameter settings.

9. The system of claim 7, wherein the set of configuration rules comprise rules specifying acceptable levels of application-level parameter settings.

10. The system of claim 7, wherein the clone is a clone of the CMDB.

11. The system of claim 7, wherein the clone is a clone of a portion of the CMDB.

12. A computer program product comprising a computer usable medium embodying computer usable program code for change verification, the computer program product including:

computer usable program code for receiving a proposed configuration change for application to a configuration management database (CMDB);

computer usable program code for cloning at least a portion of the CMDB to produce a clone; and

,

computer usable program code for applying the proposed configuration change to the clone.

13. The computer program product of claim 12, further comprising computer usable program code for proceeding to apply the proposed configuration change to a corresponding resource referenced by the clone based upon the evaluation.

14. The computer program product of claim 12, wherein the computer usable program code for cloning at least a portion of the CMDB to produce a clone, comprises computer usable program code for cloning the entire CMDB to produce a clone.

15. The computer program product of claim 12, wherein the computer usable program code for evaluating the clone as modified by the proposed configuration change, comprises:

computer usable program code for loading a set of configuration rules;

computer usable program code for evaluating data in the clone according to the set of configuration rules; and

,

computer usable program code for identifying any violations of the configuration rules in the set.

16. The computer program product of claim 15, further comprising:

computer usable program code for reporting the violations through a user interface; and

,

computer usable program code for permitting an application of the proposed configuration change to the CMDB responsive to an affirmative approval provided through the user interface.
