About NLS_LANG Parameters
Oracle provides Globalization Support that enables users to interact with a database in their own language, as defined by the NLS_LANG parameter. When you install Oracle9i components, the NLS_LANG parameter is set in the registry.
The default value of the NLS_LANG parameter at installation is automatically chosen based on the locale setting of the operating system. The operating system locale and NLS_LANG value mappings are listed under "Commonly Used Values for NLS_LANG".
NLS_LANG parameter is stored in the registry under the HKEY_LOCAL_MACHINESOFTWAREORACLEHOMEIDNLS_LANG subkey, where ID is the unique number identifying the Oracle home. The NLS_LANG parameter uses the following format:
NLS_LANG = LANGUAGE_TERRITORY.CHARACTER_SET
where:
| Specifies the language and conventions for displaying messages, day name, and month name. |
| Specifies the territory and conventions for calculating week and day numbers. |
| Controls the character set used for displaying messages. |
