changing temporary tablespace for all schemas

Hello.
All my schemas use an over-dimensioned temporary tablespace called BIGTEMP and I have to free some space on the HD, so I wish to make them to use a smaller temporary tablespace called SMALLTEMP instead. Please let me know if these steps are correct (Oracle 7.3):

1. for each schema, issue the command: ALTER USER ... TEMPORARY TABLESPACE SMALLTEMP ;
2. ALTER TABLESPACE BIGTEMP OFFLINE ;
3. delete BIGTEMP datafile (gulp!)

TIA, Cris
