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.
