If I understand correctly, session_cached_cursors causes a "softer"
parse, but a parse would still show up as a parse in the 10046 output so
I don't believe this parameter could be responsible for the 50%
reduction in parse count. Someone please correct me if I'm wrong.
Thanks,
Brandon

In the upgrade process, did you changed 'session_cached_cursors'
from 0 (default in 8i) to something like 50+?
In this case your hits are much better and there is less
pression on the shared pool, hence your parsing decrease also.
