This feature is new in the Solaris Express 11/03 release and in the Solaris 9 9/04 release.
Locale administrator allows the user to query and configure the locales for a Solaris OS through a command-line interface. Using the localeadm tool, a user can display information about locale packages that are installed on the system or that reside on a particular device or directory. The user can add and remove locales on the current system on a per-region basis. For example, the user can add all locales in the Eastern European region to the current system. See the localeadm(1M) man page.
Prior to this feature's introduction, after a system was installed the user had to add or remove individual packages to change the locales on the machine. This process is prone to error because it is easy to miss or overlook packages. This tool is a supplement to the locale selection logic in the Solaris installer. The installer is still the primary application for the correct installation of Solaris locales.
