Oracle parsing SQL with Hibernate

Question

Hi,
I build an J2EE application using framework Hibernate. After auditing DBA on any scenario from my soft, I note all request SQL executed are parsed. Same request, using "bind variable", so identical, is parse as many time it execute (ratio 1/1)... Not really powerful, isn't it?
Did somebody already encounter the problem?
Thanks

This sort of technical question needs to be addressed to one of the technical forums. Products | Database | SQL and PL/SQL would seem to be appropriate here.
Have you tried applying the latest patchset for your database? Seems to work for me on 9.2.0.5
SCOTT @ HP92 Local> select * from (
  2  select dept.*,emp.ename from dept
  3  left outer join emp on (emp.deptno=dept.deptno)
  4  )
  5  where (deptno) in
  6  (
  7  select deptno a from
  8  (
  9  select deptno,dname from dept where deptno=10
10  UNION ALL
11  select deptno,dname from dept where deptno=20
12  )
13  )
14  /
