6.9 About Running APEX in Other Languages
You can install a single instance of Oracle APEX with one or more translated versions.
The APEX developer and admin interface is translated into the 9 standard languages: French, German, Italian, Japanese, Korean, Portuguese (Brazil), Simplified Chinese, Spanish, and Traditional Chinese. Developers can choose to run the APEX development environment in any of the installed languages by simply selecting the language from the App Builder sign-in or home page.
The APEX runtime engine which is used by developers to create applications is available in the following additional languages: Arabic, Brazilian Portuguese, Croatian, Czech, Danish, Dutch, Finnish, French, French - Canada, German, Greek, Hebrew, Hungarian, Icelandic Italian, Japanese, Korean, Norwegian, Polish, Portuguese (Portugal) (pt), Romanian, Russian, Serbian - Cyrillic, Serbian - Latin, Simplified Chinese, Slovak, Slovenian, Spanish, Swedish, Thai, Traditional Chinese, Turkish, Ukrainian, and Vietnamese.
A single instance of APEX can be installed with one or more of these translated versions.
In order to install other languages you must use the apex_24.1.zip file which contains the extra files as described in Installing Translated Versions of APEX. If you previously downloaded apex_24.1_en.zip, then you do not need to re-install APEX. Simply download apex_24.1.zip and unzip the file into the same directory where you unzipped apex_24.1_en.zip.
The translated version of APEX should be loaded into a database that has a character set that supports the specific language. If you attempt to install a translated version of APEX into a database that does not support the character encoding of the language, the installation may fail or the translated APEX instance may appear corrupt when run. The database character set AL32UTF8 supports all the translated versions of APEX.
You can manually install translated versions of APEX using SQLcl. The installation files are encoded in AL32UTF8.
Note:
Regardless of the target database character set, to install a translated version of APEX, you must set the character set value of the NLS_LANG environment variable to AL32UTF8 before starting SQLcl.
The following examples illustrate valid NLS_LANG settings for loading APEX translations:
American_America.AL32UTF8
Japanese_Japan.AL32UTF8
