Hello, Uday,
First step, try ANALYZE TABLE ... COMPUTE STATISTICS for EVERY table
participating your query(es). Check and compare execution plan before and
after analyze.

Hi All,
Recently we moved the database(Oracle 8.0.5) from NT to Sun machine. Now
this database is going online very soon. When we were testing we observed
that, the application (select statement) is running very slow. (I don't know
how fast it was earlier). I have a feeling that it is not using indexes
properly. I have created 6 indexes on that table on each columns. also
created a composite indexes. How do I know that the sql is using which index
for select statement.? Is there any other ways to improve the performance?
Thanks
Uday
