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 HTML DB 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. As an Oracle HTML DB administrator, you can also purge them manually.

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