The answer is yes & no. First off tablespace data_small will go offline as soon as Oracle realizes that the datafile is gone. At this point any insert, update, or delete that involves a table and/or index in data_small will fail. Therefore there will be no inconsistencies.

Just wondering what will happen in this condition .

supposse I have two tablespaces data_large and data_small . with datafiles data_large01.dbf and data_small01.dbf . some transactions affects tables in both tablespaces . Now one day I lost data_small01.dbf data files . I thought of recovering that data file from one day old backup . when I recover this data data file , will oracle maintain transactio consistency for all transaction happened today . becuase data_large01.dbf is up to date . but data_small01.dbf is one day old . will oracle keep this in mind while applying archived logs at the time of recovery .
