If all of the application servers in a cell use the same web server to route requests for dynamic content, such as servlets, from web applications to application servers, you can create a global web server plug-in configuration file for that cell. The resulting plugin-cfg.xml file is located in the profile_root/config/cells directory.
To update the configuration settings for a global web server plug-in, you can either use the Update global web server plug-in configuration page in the administrative console, or issue the following command:
%was_profile_home%/config/cells/GenPluginCfg.sh|bat
Both methods for regenerating the global web server plug-in configuration create a plugin-cfg.xml file in ASCII format.
To use the Update global web server plug-in configuration page in the administrative console:
The delay is important because it determines how soon the new plug-in configuration takes effect. Suppose you add a new served path for a servlet, then regenerate the plug-in configurations. The regeneration requires 40 seconds, after which a user should be able to access the servlet by the new served path.
For an HTTP plug-in, the length of the delay is determined by the Refresh Interval attribute of the Config element in the plugin-cfg.xml file. The plug-in polls the disk, or file system, at this interval to see whether the configuration has changed. The default interval is 60 seconds. To regenerate the plug-in configuration requires twice the refresh interval.
In a development environment in which you are frequently changing settings in the administrative console, it is recommended that you set the refresh interval to 3 to 5 seconds.
In a production environment, set a longer refresh interval, perhaps as long as 30 minutes, depending on the frequency of changes.
You might need to stop the application servers in the cell and then start the application servers again before the changes to the plug-in configuration go into effect.
If the web server is running on a remote machine, click View or download the current web server plug-in configuration file to download a copy of the plugin-cfg.xml file to a that machine.
