I am running a 8.1.7 database.
I want to resize the datafile in my temporary tablespace.
When I try to resize i get ORA-03297: file contains used date beyond requested resize value.

I have only a single datafile.
Can I drop and re-created temp datafile while users still on the system in 8.1.7

The users have their own tablespace assigned but the temporary tablespace is given access as well as standard temp area.

thanks
