are all your tables/indexes analyzed? if the statistics are not current then the plans chosen by the CBO can be very bad.

> 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.
