I don't like to laugh at anyone's pain, but my goodness. As a great pre-med student before me said "my advice to you is to start drinking heavily".
The only way I can possibly think of an out, is if you have transaction logs/journals from the beginning of time (not sure what DB platform you are on). Then you MIGHT, we're talking being in McGyver territory here, you might be able to reinstall and then rebuild.
Hopefully the previous poster was correct in assuming that since you don't have any backups, this is a new install, in which case you either want to scratch and restart, or if on the iSeries, reinstall the system library from the install menu. I wouldn't bother with the planner to system mess.
I'm really hoping for you, the situation is the latter.
I will enjoy the creative ideas that I'm sure this post will generate.
