query not working fine
Hi
db version is 9.2.0.8.0
in dev the query is working fine.But in qa the query is not working fine(hanging).I had checked the explain plans.
Both are different.This is due to difference in volume of data.
I am pasting the explain plans of both the queries in qa and dev

I analyzed all the tables involved in it.
can anybody give me suggestion in crating indexes or anything else?
Thanks
