How have you determined that you don't have bind variable issues? Have you
also checked for the oldest culprit of all, namely SQL with literals
scattered through it. I typically look for this with something like
select substr(name,1,60), sum(sharable_mem), count(*)
from v$db_object_cache
group by substr(name,1,60)
having count(*)>50
order by sum(sharable_mem)
