Datafile was inadvertently over-written
Trying to issue SQL*Plus 'recover datafile ...' and get the following error:
SQL> recover datafile '/dbvol/oradb/ebzt/vol02/oradata/ebzt/a_media19.dbf';
ORA-00283: recovery session canceled due to errors
ORA-19909: datafile 297 belongs to an orphan incarnation
ORA-01110: data file 297: '/dbvol/oradb/ebzt/vol02/oradata/ebzt/a_media19.dbf'
Is there a way to recover this datafile?
