ORA-01194: file 1 needs more recovery to be consistent
It occurred during the case of incomplete recovery an insufficient number
of redo logs were applied to make the file consistent.
The datafile was not closed cleanly when it was last opened by the database.
Try to restore and recover the file at consistent state to overcome with this error. Apply all the available archive log to make in in consistent state. In case archive is missing to make datafile in consistent state.
If you face error again ,then only way to recover is “_allow_resetlogs_corruption” this undocumented parameter.
Before use it take your cold backup of database and alert log file backup of current state. This parameter force fully tried to make all datafiles in consistent state. So, its always better to full cold backup before use it.
