Enabling memory

You can specify memory explicitly to change its default parameters. To do so, edit the sun-web.xml file for the web application as in the following example. Note that persistence-type must be set to memory.

<sun-web-app>
         ...
        <session-config>
           <session-manager persistence-type=”memory”>
              <manager-properties>
                 <property name="reapIntervalSeconds" value="20" />
              </manager-properties>
           </session-manager>
            ...
        </session-config>
        ...
</sun-web-app>
