Have you set event 10046, lev 8 for the session? If not, try setting
it and then use 9.2 tkprof to see what is the instance waiting for
as well to analyze the execution plans and see how they differ.
Also, during the execution, you can watch v$session_wait and see what the
session is waiting for. If the event is something like 'db file scattered
read', then it is the execution plan that is causing trouble.
Try the "DBA 101" red book, written by Gaja Viyadanthaya (hopefully,
I didn't misspell his name), Marlene and comp. It's a book which
has answers precisely to questions like yours.

Hi list,
SCENARIO LAB DB = Oracle 8.1.7.4.0 on Suse Linux 7.2
PRODUCTION DB = Oracle 8.1.7.4.0 on HP-UX B.11.00
I have this strange case, I have this query that generate a text file
and in the PRODUCTION environment ran for about 30 minutes. When
running the same query in LAB ran in about 2 minutes. The 2 instances
have the same parameters setted and the same amount of data, the
Lab DB is updated every night with the production data throught IMP/EXP
procedure.
Trying to solve the problem, today I ran statistics in LAB and the query
lasted more than in PRODUCTION and before was about 2 minutes.
TIA
