Hi

Oracle is not really something I know much about yet so I may be way off base here but it sounds more like a problem with the database. Your Perl scrip may have some form of memory allocation which tells the script to load the database (supposedly quicker) and this may have been exceeded. If so, changing the allocation size in your script could solve the problem.

As I said, I am in no way an expert and this is off the top of my head so I hope it works or gives you another direction to think about and eventually resolve the error.
