is this failing? can it be found? Also, does the program fails at compilation or runtime?

Edit: It looks there is at least 1 Perl DB Driver Module (very old) on CPAN offering connection to Teradata. There is another deprecated offering a newer version outside CPAN. I would investigate this route rather than inling all code to JAVA. Limited mileage but the first thing to investigate.

Edit: note to fellow monks: teradata db access needs a proprietary driver just as mysql, sqlite et al. do. The only hope on this front is if Teradata::SQL can be made to work.
