Dynamic reconfiguration allows you to make configuration changes to a live web server without having to stop and restart the web server for the changes to take effect. You can dynamically change all configuration settings and attributes in server.xml and its associated files without restarting the server. So any changes that you make within the virtual server user interface can by applied without restarting the server. You can dynamically reconfigure your server after changes using the reconfiguration script or the user interface.
On UNIX platforms the dynamic reconfiguration script is a shell script named ’reconfig’ located in each instance’s directory. There are no commandline arguments to this script. You can run the reconfiguration script by simply typing ’reconfig’ from the server instance’s directory.
On Windows, the dynamic reconfiguration script is a batch file called ’reconfig.bat located in each instance’s directory. There are no command line arguments. You can run the reconfiguration script by simply typing ’reconfig’ or ’reconfig.bat’ from the server instance’s directory.
When run, this script initiates a dynamic reconfiguration of the server, similar to the user interface, and displays the server messages related to reconfiguration.
To access the dynamic reconfiguration screen, click the Apply link found in the upper right corner of the Server Manager, Class Manager, and Virtual Server Manager pages, then click the Load Configuration Files button on the Apply Changes page. If there are errors in installing the new configuration, the previous configuration is restored.
