Raj - I personally favor using the simpler diagnostics first. Why not run
your SQL through EXPLAIN PLAN and see which SQL is performing sorts? My
immediate guess is that under RBO an index was being used that isn't now.

I have a problem with a process and its temp segment usage. 

Previously, in RBO (8161) we used to run 8 reports with slightly different
parameters in parallel and it used to work fine with all other load on the
system and the total TEMP space was 6GB

Since we migrated to CBO (all tables & indexes are analyzed using estimate),
these processes fail with unable to extent temp segment error. Currently we
have allocated 12GB to temp tablespace.

I also have performance issues so I am doing a 10046 trace at level 8 on
this one. Is there a way to identify when this process used temp space, how
much and when does it de-allocate?

Would this information be available in 10046 trace or is there something
else that I could do to track that ... 

Thanks in advance 
Raj
