Configure Intelligent Management for web servers


Before starting

  1. Learn about the web server plug-in configuration tasks.

  2. Dynamically generating plugin-cfg.xml overwrites the Intelligent Management settings in plugin-cfg.xml, so we need to disable the dynamic generation of plugin-cfg.xml for that web server.

    At the cell level, for every web server with Intelligent Management enabled, remove custom property names that begin with ODCPluginCfg.

Enable Intelligent Management

  1. In the administrative console, click...

      Servers | Server types | Web servers | web_server_name | Intelligent Management | Enable | OK

  2. Generate the plug-in configuration file.

      In the administrative console, click...

        Servers | Server types | Web servers | web server | Generate plug-in

    • Propagate the plug-in. In the administrative console, click...

        Servers | Server types | Web servers | web server | Propagate plug-in

    • Restart the web server...

      When global security and Intelligent Management are both enabled, the web server plug-in uses the client certificate that is labeled default to communicate with the back-end cells. This certificate is issued by the cell when the web server is first created, and must be renewed by the user periodically to maintain its validity. The initial validity period is one year.


Enable the plug-in to route to multiple WebSphere cells

The plug-in routes to multiple WebSphere Application Server cells. However, the plug-in is managed from a single WAS cell. To enable the plug-in to route to multiple WebSphere cells, add remote cells to the Intelligent Management web server. If we add remote cells, the Intelligent Management configuration in the generated plug-in includes endpoint information collected from the remote cells via REST services. Ensure that the latest WAS version runs on the web server and on the remote cells.

Add remote cells to the Intelligent Management web server...

  1. Add a remote cell to the web server

    In the administrative console, click...

      Servers | Server types | Web servers | web_server_name | Intelligent Management | Remote cells | Add

  2. Specify the remote cell properties.

    Enter the remote cell information on the configuration panel, and click OK.

    To avoid connection issues, the remote cell name must be different from the name of the local cell in which the web server is located. The remote cell now displays in the remote cells list on the Intelligent Management configuration page.

  3. Generate the plug-in configuration file. In the administrative console, click...

      Servers | Server types | Web servers | web server | Generate plug-in

  4. Propagate the plug-in. In the administrative console, click...

      Servers | Server types | Web servers | web server | Propagate plug-in

  5. If we imported certificates during the remote cell properties specification step, refresh the web server keystore. Click...

      Servers | Server types | Web servers | web_server | Additional properties | Plug-in properties | Copy to web server key store directory

  6. To establish a secure connection to the remote cell, import the local cell certificate into the remote cell. In the administrative console for the remote cell, click...

    If we enable Intelligent Management on the web server, and change the global security setting, the HTTP or HTTPS protocol does not change on the Intelligent Management web server connectors. In order for the security change to be reflected on the Intelligent Management web server connectors, run the refreshCellForIntelligentManagement command on local and remote cells. To propagate the security change to remote cells, use the refresh button on the remote cell. In the administrative console for the remote cell, click...

      Servers | Server types | Web servers | web_server_name | Intelligent Managment | Refresh button

  7. Restart the web server

      Servers | Server types | Web servers | web server | Stop | Start


Disable Intelligent Management

  1. In the administrative console, click...

      Servers | Server types | Web servers | web_server_name | Intelligent Management | clear the Enable check box

  2. Generate the plug-in configuration file.

    In the administrative console, click...

      Servers | Server types | Web servers | web server | Generate plug-in

  3. Propagate the plug-in.

      Servers | Server types | Web servers | web server | Propagate plug-in

  4. Restart the web server.

      Servers | Server types | Web servers | web server | Stop | Start
