Hi, I tried dbv today with 11.1.0.06 on RHL4, normal cooked file system. I get: dbv file=system01.dbf blocksize=8192 DBVERIFY: Release 11.1.0.6.0 - Production on Tue Jul 14 10:07:17 2009 Copyright (c) 1982, 2007, Oracle. All rights reserved. DBV-00600: Fatal Error - [21] [2] [0] [0] MetaLink lists a bug (Bug 6820317 -) about not having write access the file, but this is not the case here and the error message is different. I only tried this because over-night the some oddity made the root file system read only and we had to reboot. Any one else seen this? Regards Pete
