Hi All,

ALL tables are analyzed
Tables and index have degree =1
No hint for the parallelism is

No,
tables are not partitioned

Whoops, I
sent my earlier message too fast.
You've
already checked the degree on table
and
index. Hmmm... Puzzling...
I'm curious
to see the answer if you ever get one.

What does v$pq_sysstat show? What does v$pq_sesstat show? (If session is
still connected).

So, it is clear that there is PQ in use here. Are you sure the query in
question is really using PQ servers?
Can you run that query again via another session? If so, please post
contents of v$pq_sesstat as seen right after the query ends.
Thanks.
