Good day all,
I have a query that has been a stumper for the past couple of days -
Oracle 8.0.5
HPUX 11
When running it in Dev environment, it does a full table scan on a large
table and the performance is terrible. But when running it in prod
environment, it uses the index and the performance is great. Both Dev and
Prod are running with Rule-based ( this is Oracle Apps so we don't have a
choice ). Also Dev is a 'clone' of prod from about 2 weeks ago.
The only thing I have a funny feeling about is that while Rule-based
optimizer is set in init.ora, all the tables are analyzed with a 2001 date (
done by previous DBA ). But since both environment have the same statistics,
I don't think this can make a difference. I deleted statistics from the
table in Dev and the plan remains the same.
TIA
Dennis
