Steve, You may have to dig a little further... What happened to those table(s) in that schema prior to starting the export? Heavy DML, may be? This could be a case of 'delayed block cleanout'. Export triggered the cleanout and wanted to access the rollback segments.
If no table data was modified after export started reading that table, then there is no need to read RBS info (except for the DBC case, IMO). - Kirti --- "Orr, Steve" <[EMAIL PROTECTED]> wrote: > Oh yeah, for the export consistent=N > > -----Original Message----- > Sent: Thursday, May 29, 2003 9:14 AM > To: '[EMAIL PROTECTED]' > > > A certain alignment of the planets occurred creating a good ole ORA-01555 error...
