If he hadn't launched this and forgotten about it, there would be a ton of things that he could have done to make it easy now. He didn't and it isn't.
I'll suggest gdb to him. Figuring out the right program may be hard though - he's running a Perl script which connects to Oracle and does stuff. I'm not sure that he has the source to the Perl that he is executing this with. :-(
Any other ideas?
