DB2 10.5 for Linux, UNIX, and Windows

Displaying the DB2 Setup wizard in your national language (Linux and UNIX)

The db2setup command queries the operating system to determine the existing language settings. If the language setting of your operating system is supported by db2setup, then that language will be used when displaying the DB2 Setup wizard.

If your system uses the same code pages but different locale names than those supported by the interface, you can still see the translated db2setup by setting your LANG environment variable to the appropriate value by entering the following command:
bourne (sh), korn (ksh), and bash shells:
LANG=locale
export LANG
C shell:
setenv LANG locale
where locale is a locale supported by the interface.
