Well, of course the process needs to be reconfigured but that's not the point at all. The point is, why are objects in a readonly tablespace vulnerable to being dropped? That's counterintuitive behavior even if it does make sense after thinking about the implementation. I think the original poster was asking if she can make readonly tablespaces act with the expected behavior.

The best idea I've seen has been the trigger option from Juan. I haven't looked at triggers at the DB level so I'm not sure how much security it'll provide, but at least it holds promise. For example: SQL> create trigger boo
  before drop
  on database
DECLARE
  eERROR exception;
begin
  raise eerror;
end;
/
  2 3 4 5 6 7 8 9
Trigger created.

SQL> create table boojam (a number);

Table created.

SQL> drop table boojam;
drop table boojam
*
ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 1
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at line 4

Just needs a lot of spiffing up.
