Hi,
Tables Analyzed recently?
Indexes analyzed recently?
Histograms possibly?
If all else fails hints are there to force a certain execution anyway
(Oracle must have known that the CBO wasn't/isn't perfect) so just use
them.

Dear All,
I have been entrusted to tune a web based application. This product is at
development stage. I generated the trace file and found out the indexes on
the table. So I specified hints in all the queries and tested the
application. There was a remarkable increase in performance. Can any one
tell me why we have to specify the hints in the queries, when the tables
are having index already.
Platform: WinNT Oracle 8.1.6. Application is developed in JSP and Web
server is iPlanet Enterprise Edition.
TIA
Regards
Venkat
