Hi

What is the query?
What is the explain plan w/o hints?
what is th eexplain plan with hints?

Is it doing hash joins w/o hints (Full table scans) and nested loops with

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
