Managing Session State

A session is a logical construct that is used to establish persistence (or stateful behavior) across page views. Each session is assigned a unique ID, which the Application Express engine uses to store and retrieve an application's working set of data (or session state) before and after each page view. An automatic process clears sessions older than 24 hours every eight hours. Oracle Application Express administrators can also purge them manually.

An Oracle Application Express administrator can view session state statistics and purge the session state on the Session State page.
