CREATE CONTROLFILE REUSE DATABASE "EDWPROD" RESETLOGS  ARCHIVELOG
*
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01189: file is from a different RESETLOGS than previous files
ORA-01110: data file 2: '/ora/prod/edwprod/data/EDWPROD/datafile/o1_mf_undotbs1_334h0kxm_.dbf’

?

原因：

In order to recreate the controlfile, all datafiles must be at the same incarnation, or resetlogs time.
We cannot allow datafiles to be at different incarnations.
