Re: Cold DB copy-- Create controlfile error

1. If you say that the source database was shutdown yesterday then all datafiles in that database would have been checkpointed and timestamped yesterday. If that one file has an older timestamp (ie it did not get updated by the database shutdown checkpoint) then it seems as if that file does not belong to the current incarnation (since the last resetlogs) of the source database.
2. Was the source database itself created as a copy of another with incomplete recovery and resetlogs OR was the source database at some point opened with a resetlogs ? Can you find out why ?
3. If you can mount the controlfile (or open) of the source database, you can query V$DATAFILE / V$DATAFILE_HEADER or just do a BACKUP CONTROLFILE TO TRACE to list all the datafiles that "belong" to the source database.
4. If this one datafile really doesn't belong to the database how did it get included in your CREATE CONTROLFILE script ? Was the CREATE CONTROLFILE script manually written or really generated from a BACKUP .. TRACE ?
