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
