5.    Start Oracle database in mount state with 

STARTUP MOUNT 

6.    Modify the name or location of datafiles in Oracle dictionary using following command syntax:

ALTER DATABASE RENAME FILE ‘<fully qualified path to original data file name>’ TO ‘<new or original fully qualified path to new or original data file name>’;

ALTER DATABASE OPEN 

If the datafiles that need to be changed or moved do not belong to SYSTEM tablespaces, and do not contain active rollback segments or temporary segments, there is another workaround that does not require database instance to be shutdown. Instead, only the particular tablespace that contains the date files is taken offline.
