I am doing 9ir2 hot backup/recovery test.  I got
problem on tempfile (temporary tablespace)
drop problem.

I can drop tempfile under "mount" mode, but NOT under
database open:

SQL> startup mount 
ORACLE instance started.

Total System Global Area  202880128 bytes
Fixed Size                   451712 bytes
Variable Size              83886080 bytes
Database Buffers          117440512 bytes
Redo Buffers                1101824 bytes
Database mounted.
SQL> alter database tempfile
'/apps/oradata/eaii/temp01.dbf' drop;

Database altered.

SQL> alter database open;

If I use same command when database open.  It will
hang in there for ever.

Can anyone tell me how to drop tempfile  when database
open?

Thanks.
