ORA-04089

Looking through some old documentation, I read that you cannot create triggers on tables owned by SYS. I decided to see if this still applies in Oracle 11.2 and it does:

SQL> create trigger andrews_trigger

  2  after insert on sys.impdp_stats

  3  begin

  4  null;

  5  end;

  6  /

create trigger andrews_trigger

               *

ERROR at line 1:

ORA-04089: cannot create triggers on objects owned by SYS
