Abstract

A method and apparatus for virtualized and adaptive configuration. An embodiment of a method includes generating a system configuration. The configuration includes a setting, with the setting having an abstract value to be resolved based at least in part on a characteristic of a system. The configuration is installed in a recipient system, and a value is resolved for the setting based at least in part on a characteristic of the recipient system.

Claims

1. A method comprising:

generating a self-adapting system configuration, the configuration including a setting for a system dependent element, the setting having an abstract value to be resolved based at least in part on a characteristic of a system receiving the system configuration;

installing the configuration in a recipient system;

resolving the value for the setting for the recipient system based at least in part on a characteristic of the recipient system, wherein resolution of the value of the setting occurs at runtime for the recipient system; and

dynamically adapting the system configuration by changing the value of the setting based at least in part on a change in the characteristic of the recipient system.

2. The method of claim 1, further wherein the configuration is adaptable to a plurality of different systems.

3. The method of claim 1, further comprising installing the configuration in a second system and resolving the setting for the second recipient system based at least in part on a characteristic of the second recipient system, the value of the setting for the second recipient system being different than the value of the setting for the recipient system.

4. The method of claim 3, wherein installing the configuration in the second system includes transferring the configuration from the recipient system to the second recipient system without making any modifications to the configuration.

5. The method of claim 1, further comprising obtaining an abstract element from a database for the setting.

6. A server comprising:

a database to contain a set of abstract configuration elements for a configuration; and

a resolving engine to receive an abstract configuration element from the set of abstract configuration elements, the resolving engine to resolve a value for the abstract configuration element at runtime for a recipient system, the value to be resolved for the purposes of the recipient system for the; and

a set of characteristic values for the recipient system, the resolving engine to obtain a characteristic value from the set of characteristic values and to resolve the abstract configuration element based at least in part on the characteristic value;

wherein the resolving engine is to dynamically adapt the system configuration by changing the value of the abstract configuration element based at least in part on a change in the characteristic value for the recipient system.

7. The server of claim 6, wherein the resolving engine is to resolve a value for the abstract configuration element for the purposes of a second recipient system to receive the configuration, the second recipient system being different than the recipient system.

8. The server of claim 6, wherein the resolving engine comprises an API (application program interface).

9. The server of claim 8, wherein API methods of the resolving engine are used to generate a runtime configuration out of the abstract configuration elements of the configuration.

10. The sewer of claim 6, wherein the only static settings included in the configuration are non-system dependent settings.

11. The sewer of claim 6, wherein the server is a Java 2 Enterprise Edition (“

J2EE”

) compatible server that supports Enterprise Java Bean (“

EJB”

) components.

12. A computer-readable medium having stored thereon data representing sequences of instructions that, when executed by a processor, cause the processor to perform operations comprising:

producing a configuration for a recipient system, the configuration including an element with a value that is to be resolved based at least in part on a system characteristic;

determining a recipient system for the configuration;

resolving the value of the element of the configuration at runtime for the recipient system based at least in part on a characteristic of the recipient system; and

dynamically adapting the system configuration by modifying the value of the element of the configuration based on a modification in the characteristic of the recipient system.

13. The medium of claim 12, wherein the produced configuration does not contain any element that is dependent on the system that receives the configuration.

14. The medium of claim 13, wherein the characteristic of the second recipient system is different than the characteristic of the recipient system.

15. The medium of claim 12, farther comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:

determining a second recipient system for the configuration; and

resolving the value of the element of the configuration based on a characteristic of the second recipient system.

16. The medium of claim 12, wherein the resolution of the elements of the configuration is done by a configuration machine.
