once, i had experience when my applications and database have
different values for nls_lang, and i had to make them the same before
doign anythign else..

and of course, i set them to the same value as the database...


also, one of the warnings messaeg is that if i messed up this
nls_lang, my database would be corrupted.. i am not sure how this is
goign to happen but i am not going to take chances so just changed the
value as the database and all is fine.
