Hey Dave,

Are you issuing this thru SQL*Plus or Server Manager? Or another package like TOAD, that could be issuing some background queries'n'things that may be locking the table on you?

Since this is a test system, I wonder what kinf of trace you'd get by setting event 4020?

I am trying to do a TRUNCATE TABLE My_Table but keep getting this error;

A self-deadlock among DDL and parse locks is detected. In most cases, this self-deadlock is handled internally.
This should be reported to Oracle Support ONLY IF an error is signalled back to the user on a command-line or screen.
The following information may aid in finding the problem.
ORA-04020: deadlock detected while trying to lock object DFARNSWORTH.REGION_ZIPS This is in my test environment and there should not be anything else locking the table. Any ideas??

Thanks,

Dave
