The ora-03124 has nothing to do with DBB::Oracle as this is either a disk/space issue a lisence issue (as in you do not have the correct one) or you are trying to stuff too much data into a single row or field. You will have to look at you oracle logs to see what is going wrong. As it ran once I would go the too much data in a row or field and it might have something to do with non UTF8 chars By they way no one but me actully look at this list (and I only when I have some spare time) You would be much better off posting this at http://www.nntp.perl.org/group/perl.dbi.users/ or raise a RT ticket at http://rt.cpan.org/Dist/Display.html?Queue=DBD-Oracle
