ORA-01211: Oracle7 data file is not from migration to Oracle8



ORA-01211: Oracle7 data file is not from migration to Oracle8..

Answer / guest

Cause: The file is not a copy of the file LAST used under
Oracle7. This datafile is either a backup taken from before
the migration, or the database was opened by Oracle7 after
the migration utility was run. When converting a database
from Oracle7 to Oracle8, the migration program MUST be the
LAST utility to access the database under Oracle7. Only the
datafiles that were current when the migration was done may
be accessed by Oracle8.

Action: Have operating system make correct data file
available to database, or repeat the Oracle7 to Oracle8
migration. Make sure that database is NOT opened after
migration utility is run.
