For every session it exposes the wait event name, how long the session has been in that wait, and three event-specific parameters (<code>P1</code>, <code>P2</code>, <code>P3</code>) that pinpoint the resource — a file and block number, a lock type, a latch address. It is the view to reach for when the database &quot;feels slow right now&quot; and you need the current state, not a post-mortem from AWR.</p>
