Goal

How to recreate a datafile that is missing at the operating system level. Missing/inaccessible files may be reported with one or more of these errors:

ORA-01116: error in opening database file %s
ORA-27041: unable to open file
ORA-01157: cannot identify/lock data file %s - see DBWR trace file
ORA-01119: error in creating database file '%s'



No backup or copy of the datafile is required. We only need the redo logs starting from the time of the datafile creation to the current point in time.

Note: plugged-in datafiles do not apply in this scenario and needs to be plugged-in again from its source.
