ORA-01195:

online backup of file string needs more recovery to be consistent
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file is an online backup which must be recovered to the time the backup ended.
Action: Either apply more logs until the file is consistent or restore the database files from an older backup and repeat recovery.
