Hi
Since ur database in in archive log mode you can go
for following method also
just move your datafile to some other place. This is
just for backup. Now create a new datafile based on
existing datafile using following command
alter database create datafile'old_datafile_name+path'
as 'new_datafile_name+path'
where old_datafile_name+path will be the path and name
of ur orginal datafile which u have renamed and
new_datafile_name+path will be the name and path u
desire
Then perform media recovery for that new datafile
using
recover datafile 'new_datafile_name+path'
This method is basically used to recreate and recover
damaged datafile
However for this u must have all archive log files
since orginal datafile was created
Hope so this may help u
