Tablespaces resides in datafiles. If you don't have a file, you don't have a tablespace. When you moved these datafiles and brought the database back up, are they not still associated to the system tablespace?

Well, I have recieved a server and found some datafiles are reside in System tablespace - in this case to move those datafile we can not put system tablespace offline therefore can not use alter command...

well, I can think of one off the top of my head -- your way the database has to be shutdown.

using alter database rename file you can just take the tablespace that owns that datafile offline and do the work. All users who don't need that particular tablespace are not affected.
