System Locale Name Management

Mechanisms are provided for performing a locale name modification operation. The mechanisms receive, via a locale name management user interface presented by the data processing system, a new locale name to be used by the data processing system to perform locale customized operations. The mechanisms identify an existing locale name to be replaced by the new locale name. The mechanisms map the new locale name to existing locale name data structures associated with the existing locale name to be replaced and verify proper operation of a software element using the new locale name and the mapping of the new locale name to the existing locale name data structures. The mechanisms utilize the new locale name to perform locale name customized operations in response to verifying proper operation of the software element.
