DB2 supports many code sets and locales without translating the messages for the corresponding languages. Supporting a locale means that you can create and use a database in that locale, but you may have to view all panels and messages in a different language, if translated messages are not available in DB2. For a complete list of locales supported, refer to the Administration Guide.
If you want to operate in a different language environment, do the following:
For example, to use fr_FR messages on DB2 for AIX, you must have the fr_FR message option installed and must set LANG to fr_FR.
The selected message catalog filesets are placed in the /usr/lpp/db2_05_00/msg/%L directory on the target workstation, where %L is equal to the locale name of the message catalog.
