Not matching the SYS_CONTEXT('USERENV', 'LANG') with oracle fod schema data

Question

I have imported the fod schema into oracle XE. I observed that the data available for following languages:
SQL> select distinct language from category_translations;
LANGUAGE
EN
EL
FR
DE
JA
But, when I check the value for the LANG in oracle XE, it is returning as 'US'.
SQL> select SYS_CONTEXT('USERENV','LANG') FROM DUAL;
SYS_CONTEXT('USERENV','LANG')
US
Becasue of this, I am not getting data when I run VOs from JDeveloper. Even I am not able to see data from FOD schema views.
Please suggest what changes I need to do for getting data.

Answer 1

Try this,it will work
alter session set nls_language = 'GREEK'
If the above query is used,it will set the current session's language code to 'GL' which is valid in the language filed of category_translations.
I did not find any nls_language value to get the 'EN' code.
You can get the valid language values from the below query:
select * from V$NLS_VALID_VALUES where parameter='LANGUAGE'
