Regenerating the plug-in configuration file does not guarantee a correct configuration for advanced configuration scenarios. If your use of the WebSphere Application Server product requires a plug-in configuration more advanced than the configuration that is provided with the default plug-in configuration, or if the plug-in does not behave properly after the configuration file is regenerated, you can manually edit the configuration file to obtain the proper plug-in behavior for your environment.
If the plugin-cfg.xml file is generated through the Update Web Server plug-in Configuration page in the administrative console or with the GenPluginCfg.sh script, the file is in ASCII format.
Open the plugin-cfg.xml file in a text editor. By default, the file is located in the /QIBM/UserData/WebASE51/ASE/instance/config/cells directory, where instance is the name of your application server instance.
Make your changes to the plug-in configuration file. For descriptions of the elements and attributes in the plugin-cfg.xml file, see The plugin-cfg.xml file.
NOTE: If the plug-in configuration is regenerated, your changes to the plug-in configuration file are overwritten. It is recommended that you maintain a record of your manual changes.
Save the file.
