---------------------------------------
Please, I didn't catch why no one is moving on this important issue.
How are u using DIH in production? without prepared stamentent? If so, why
yours DBAs don't claim?
May be there is a different basic solution that I cannot see. Please anyone
aware of it, advice me.
Regards to all.
