Recreating a trigger in a 'live' system

Assuming
I have the following :

create
table t1 (x number);
create
table t2 (y number);create
or replace trigger aifer_t1 after insert on t1 for each row
begin
insert
into t2 values (:new.x);
end;
/

And
my application frequently executes :

insert
into t1 values (:some_value);

If I
recreate the trigger in a 'live' system, is Oracle able to somehow ‘suspend’ inserts on t1 whilst the trigger is being recreated (using breakable parse locks ?) and thereby ensure that all inserts have fired the trigger ?
Or is it possible that some inserts into t1 will not fire the trigger during the brief time it was being recreated ?regards peter b
