look at the server performance. check cpu and memory utilization. This is the first step i take if overall database performance goes down. If this is ok. check the various hit ratios like buffer cache/library cache/dictionary cache and so on.. There are various other v$ views at database level that you can look at namely v$system_event/v$session_event/v$session_wait each will give you wealth of information about different aspects of your db health. But for this you need to have good understanding of these view.
