Hi guys, I have inherited an 80gb financial database which has huge data processing run on it nightly and we believe is excessively large and not performing as well as it could. I am in financial systems but new to databases. My questions are; 1. Which are the best database performance monitoring utilities? 2. Any diagnostic tools to spot problems/issues in a db? 3. Can anyone suggest any good books on db administration/optimisation? Thanks, Mark.
