Hi again,

I tried NLS_LANG too. But still same result.
My database settings are:
NLS_LANGUAGE=AMERICAN
NLS_TERRITORY=AMERICA
NLS_CHARACTERSET=WE8ISO8859P1

I tried:" export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1", but still 
execution of script gave me same error.
I can connect to database through sqlplus and run queries.
I'm working on HP-UX, and database is also on an HP-UX machine.
LD_LIBRARY_PATH is also correct. :-(

We have reinstalled DBI and other related packages. But that also didn't 
work.

Regards,
Sandeep
