Generate a plugin-cfg.xml - ODRs

In an environment with an IBM HTTP server routing requests to an on demand router, the plugin-cfg.xml configuration file forwards requests to the appropriate target servers. Each ODR can generate a plugin-cfg.xml file, which includes all the handled URIs.

If we enable Intelligent Management for a web server, DO NOT use the option to dynamically generate plugin-cfg.xml for that web server. Dynamically generating plugin-cfg.xml overwrites the Intelligent Management settings in plugin-cfg.xml.


  1. Generate plugin-cfg.xml using the ODR.

    We can override the default attributes. Generate plugin-cfg.xml in a high availability environment. This ensures that, despite the other processes available, the configuration is always generated by one process in the cell.

    In a multi-cell environment, ODRs in different cells generate cell-specific plugin-cfg.xml files. We can merge plugin-cfg.xml files for different cells into a single plugin-cfg.xml file using the pluginMerge script.

  2. Install the new plugin-cfg.xml file on the IBM HTTP server.
