Traces all queries that are sent by the application

Question

Hi to all,
I am gokhan,
I am trying to trace and monitor all the queries that are coming from the application servers to oracle db.
Oracle version : Standart Edition 11g r2
I can see the succesfull queries by looking at the V$SQL table but I want to see the queries that have parsing or other types of errors.
Is there a tool that I can monitor all the gueries, their errrors and if they are succesful paremeters that are sent to database and the binding variables that is returned by the database.
An api or methodology would also be fine.
Thanks in advance.
Regards.
Gokhan

Answer 1

I mean
if i execute this query
select sysdate, user from dual;
and then
select * from v$sql order by last_load_time desc;
I can see the query in the table but when i execute the foolowing query which gives INVALID IDENTIFIER error
select sysdateA, user from dual;
and then
select * from v$sql order by last_load_time desc;
I can not see the query in the table.
So I want a table that shows all queries even it has error and not succesfully executed..
