Abstract

A method for configuring software modules that includes accessing a properties repository that includes a plurality of properties of the execution environment of the computer system. The method further includes generating a configuration file for each software module. Generating a configuration file includes obtaining a generator module defined for the software module, and executing the generator module to instantiate the configuration file for the software module. The generator module is configured to identify a property required for the configuration file, obtain the value for the property from the properties repository, and store the value for the property in the configuration file in accordance with a customized format required by the software module. The method further includes storing the configuration file for each of the software modules.

Claims

1. A method for configuring a plurality of software modules to execute in an execution environment on a computer system, comprising:

accessing a properties repository comprising a plurality of properties of the execution environment of the computer system, wherein each of the plurality of properties comprises a name and a value;

generating a configuration file for each of a plurality of software modules using the properties repository by;

obtaining a generator module defined for the software module;

executing the generator module on the computer system to instantiate the configuration file for the software module, wherein the generator module is configured to;

identify a property of the plurality of properties required for the configuration file;

obtain the value for the property from the properties repository; and

store the value for the property in the configuration file in accordance with a customized format required by the software module; and

storing the configuration file for each of the plurality of software modules.

2. The method of claim 1, wherein generating the configuration file for at least one of the plurality of software modules is performed after initiating boot up of the computer system and prior to initiating a load routine to start execution of an operating system in the execution environment.

3. The method of claim 1, wherein the execution environment is a virtualized execution environment.

4. The method of claim 1, wherein the plurality of software modules are located in a plurality of software images.

5. The method of claim 1, wherein each software image comprises the generator module defined for the software module.

6. The method of claim 1, wherein a software image comprises the generator module for each software module of the plurality of software modules.

7. The method of claim 1, wherein the generator module for each of at least two software modules of the plurality of software modules references an identical property in the properties repository.

8. The method of claim 1, wherein the generator module defined for at least one software module is further configured to:

obtain a new property required for the configuration file of the at least one software module, wherein the new property is not stored in the properties repository; and

store a value for the new property in the configuration file in accordance with the format required by the at least one software module.

9. The method of claim 8, further comprising:

identifying the new property stored in the configuration file of at least one software module; and

storing the new property in the properties repository.

10. The method of claim 1, further comprising:

transmitting each of a plurality of software images comprising the plurality of software modules to each of a plurality of nodes in a cluster, wherein the plurality of nodes comprises a heterogeneous properties repository, and wherein each of the plurality of nodes executes the generator using the properties repository on the node to create the configuration file customized for the node.

11. The method of claim 1, further comprising:

extracting a properties file from a software image;

accessing the plurality of properties from the properties file; and

storing the plurality of properties in the properties repository.

12. A system for configuring a plurality of software modules to execute in an execution environment on a computer system comprising:

a processor;

a properties repository comprising a plurality of properties of the execution environment of the computer system, wherein the each of the plurality of properties comprises a name and a value; and

a generator manager executing on the processor and configured to;

generate a configuration file for each of the plurality of software modules using the properties repository by;

obtaining a generator module defined for the software module;

executing the generator module on the computer system to instantiate the configuration file for the software module, wherein the generator module is configured to;

identify a property of the plurality of properties required for the configuration file;

obtain the value for the property from the properties repository; and

store the value for the property in the configuration file in accordance with a customized format required by the software module; and

store the configuration file for each of the plurality of software modules.

13. The system of claim 12, wherein generating the configuration file for at least one of the plurality of software modules is performed after initiating boot up of the computer system and prior to initiating a load routine to start execution of an operating system in the execution environment.

14. The system of claim 12, wherein the execution environment is a virtualized execution environment.

15. The system of claim 12, wherein the generator module for each of at least two software modules of the plurality of software modules references an identical property in the properties repository.

16. The system of claim 12, wherein the generator module defined for at least one software module is further configured to:

obtain a new property required for the configuration file of the at least one software module, wherein the new property is not stored in the properties repository;

store a value for the new property in the configuration file in accordance with the format required by the at least one software module.

17. The system of claim 16, wherein the generator manager is further configured to:

identify the new property stored in the configuration file of at least one software module; and

store the new property in the properties repository.

18. The system of claim 12, further comprising:

an interpreter configured to interpret the generator, wherein executing the generator comprises initiating the interpreter to interpret the generator.

19. A computer readable medium comprising computer readable program code embodied therein for causing a computer system to:

access a properties repository comprising a plurality of properties of an execution environment of the computer system, wherein each of the plurality of properties comprises a name and a value;

generate a configuration file for each of the plurality of software modules using the properties repository by;

obtaining a generator module defined for the software module;

executing the generator module on the computer system to obtain the configuration file for the software module, wherein the generator module is configured to;

identify a property of the plurality of properties required for the configuration file;

obtain the value for the property from the properties repository; and

store the value for the property in the configuration file in accordance with a customized format required by the software module; and

store the configuration file for each of the plurality of software modules.

20. The computer readable medium of claim 19, wherein the plurality of software modules are located in a plurality of software images defined for a virtualized execution environment.
