Sun Java System Web Server 7.0 Update 4 Developer's Guide to Java Web Applications

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.

            <session-manager persistence-type=”mmap”>

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