Connor, It's 0130 AM here and I'm working on a DB that won't come up after we restarted it after a cold backup. This is after we spent 24 hours recovering it from veritas yesterday. I'm a little (lot) groggy.

        What's the fastest way to unveil the scenario you described below?

	Thanks
	Larry

Another thing to look for is the (poor) practice of people leaving their check constraints with
auto-generated names (SYS_C....). When you export/import et al, you can get 'n' copies of the
same constraint.

My favourite example is a vendor that once sent us a seed data export dump file with some 300
copies of the same constraint on SYSTEM.DEF$...(something) because they always unload/reloaded
with a FULL=Y. This was picked up because it took longer to import this (virtually empty) table
then any table in the import!
