You can configure additional locales by using the Locale administrator tool. Using the localeadm(1M) tool, you can display information about locale packages that are installed on the system or that reside on a particular device or directory. You can add and remove locales on the current system on a per-region basis. For example, you can add all locales in the Eastern European region to the current system.
The locale administrator now enables you to automatically add and remove locale packages on a per-region basis on the machine, once the system is installed. Because of this capability, you need not work with individual packages, and thus errors are reduced.
The locale administrator is a supplement to the locale selection logic in the Oracle Solaris installer. The installer is still considered as the primary application for the correct installation of Oracle Solaris locales.
