Unfortunately, it looks like it. But perhaps you can recover your data by exporting on a per something basis, 'something' being either owner or tables or whatever, just trying to circle around the problem. Which is why you should check dba_extents (somebody posted the query). It will tell you which table is screwed up, and you may be able to use an export function which does NOT export what is held in this table. You have good blocks around the bad one, the problem is to tread carefully around. Kind of minefield with a single mine in it. Of course no need to do this kind of thing if you have a reasonably recent backup and do not care too much about the transactions you might lose. -- Regards, Stephane Faroult Oriole Corporation Voice: +44 (0) 7050-696-269 Fax: +44 (0) 7050-696-449 Performance Tools & Free Scripts -------------------------------------------------------------- http://www.oriole.com, designed by Oracle DBAs for Oracle DBAs -------------------------------------------------------------- -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephane Faroult INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
