What are wait events. Describe the wait event tables...

Answer / surya

Many of these wait events are tied to the internal implementation of Oracle and therefore are subject to change or deletion without notice. Application developers should be aware of this and write their code to tolerate missing or extra wait events.

The following SQL statement displays an alphabetical list of all Oracle wait events and the wait class to which they belong:

SQL> SELECT name, wait_class FROM V$EVENT_NAME ORDER BY name;
