Juan,
Find out whether datafile needs recovery or not by selecting V$DATAFILE_HEADER.

Hi I don 't know if you know please how to fix this error
ORA-01251 (See ORA-01251.ora-code.com): Unknown File Header Version read for file number
The datafiles was copied, but for some reason in windows xp, (problem didn 't
happen with other databases), can recognize a readonly datafile, then the
tablespace was offile, copying again and trying to put online I got the
previous error.
The datafile is there, all is ok, v$datafile checked, etc., I don 't know if
there is a trick to fix it.
Thanks
