Sun Java System Web Server 7.0 Performance Tuning, Sizing, and Scaling Guide

Mapping Web Server 6.1 Tuning Parameters to Web Server 7.0

Many of the tuning parameters that were tunable by editing the magnus.conf and nsfc.conf files in Web Server 6.1 have moved to the server.xml file. These tuning parameters are now tunable through the Admin Console and command-line interface. The following table shows selected tuning parameters, including the Web Server 6.1 parameter, the new server.xml element used for tuning, and the way to change the parameters through the user interface. Editing the server.xml file directly can be error-prone, so using the user interface to set values is preferable. For a complete list of all elements in server.xml, see Chapter 3, Elements in server.xml, in Sun Java System Web Server 7.0 Administrator’s Configuration File Reference.
