When unixODBC (odbc.ini and odbcinst.in) files are under /usr/local/etc/. My application works fine.
I deleted the unixODBC files from /usr/local/etc/ and copied .odbc.ini and .odbcinst.ini files under home/$USER directory. I have done the environment variable setup for the .odbc.ini files. But while connecting to the database using the OTL library, I am getting the following error
[unixODBC][Driver Manager]Data source name not found, and no default driver specified
Thanks for your help
