Tip

Keep track of dropped objects

This procedure gives information about the objects being dropped from a database, such as the name and type of the object, the user who is dropping the object, terminal, etc. Here's what to do:

  1. Create a table with the following structure:
  2. USER_NAME 
    SESSION_ID     
    MACHINE        
    STATUS         
    DATETIME       
    CHANGED_OBJECT 
    OBJECT_OWNER   
    OBJECT_TYPE    
    
  3. Create a public synonym for this table.
  4. Grant insert privileges to all the users of this table.
  5. Create or replace trigger logon_trg after drop on database.
begin   
insert into dbobject_statistics values 
(lower(ltrim(rtrim(user))),userenv('sessionid'),
 lower(ltrim(rtrim(userenv('terminal')))),
'drop',sysdate,ora_dict_obj_name,ora_dict_obj_owner,ora_dict_obj_type);
end; 

By querying this table, we now know the users that are dropping objects in the database.

Reader Feedback

Alberto T. writes: I appreciate this tip but it works only in 8.1.7. In fact, database functions like ora_dict_obj_name, ora_dict_obj_owner, and ora_dict_obj_type are not available in versions like 8.0.6 or 7.3.4. So how do you solve the same matter in those versions? Any suggestions?
