Enabling MMap

You can enable MMap to change its default parameters. You can also enable MMap for a particular context if the server is running in single-process mode. 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 mmap.

<sun-web-app>
        ...
        <session-config>
            <session-manager persistence-type=”mmap”>
              ...
          </session-manager>
           ...
        </session-config>
        ...
</sun-web-app>

For more information about the sun-web.xml file, see Chapter 9, Deploying Web Applications.
