Configure Intelligent Management for web servers

Enable Intelligent Management on the web server to use Intelligent Management capabilities.

To learn about the web server plug-in configuration tasks, read about selecting a web server topology.

Before you enable Intelligent Management for a web server, disable the dynamic generation of the plugin-cfg.xml file for that web server. Remove all the cell custom property names that begin with ODCPluginCfg, if they apply to a web server with Intelligent Management enabled. Dynamically generating the plugin-cfg.xml file overwrites the Intelligent Management settings in the plugin-cfg.xml file. To learn about the dynamic generation procedures, read about generating the plug-in configuration in a high availability environment, or about configuring an ODR to dynamically update the web server plug-in configuration.

• Enable Intelligent Management:

  1. In the console, click Servers > Server types > Web servers > web_server_name > Intelligent Management, and select the Enable check box. Click OK.

  2. Generate the plug-in configuration file. In the console, click Servers > Server types > Web servers . Select the web server and click Generate plug-in.

  3. Propagate the plug-in. In the console, click Servers > Server types > Web servers . Select the web server and click Propagate plug-in.

  4. Restart the web server. Go to Servers > Server types > Web servers , select the web server, and click Stop, then click Start to start the server again.

     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.

• The plug-in routes to multiple WAS 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 that is collected from the remote cells via REST services. See the diagram in the Intelligent Management web server overview for more information. Ensure that the latest WebSphere Application Server version runs on the web server and on the remote cells. To add remote cells to the Intelligent Management web server, follow this procedure:

  1. Add a remote cell to the web server. In the console, click Servers > Server types > Web servers > web_server_name > Intelligent Management. In the Remote cells section click Add.

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

     Avoid trouble: 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.gotcha 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 console, click Servers > Server types > Web servers . Select the web server and click Generate plug-in.

  4. Propagate the plug-in. In the console, click Servers > Server types > Web servers . Select the web server and click 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 , and select the web server. Under Additional properties, select Plug-in properties. Click 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 console for the remote cell, click Security > SSL certificate and key management > Key stores and certificates > CellDefaultTrustStore > Signer certificates . Click Retrieve from port.

     Avoid trouble: 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 console for the remote cell, click Servers > Server types > Web servers > web_server_name > Intelligent Managment, and click the Refresh button.gotcha

• Disable Intelligent Management:

  1. In the console, click Servers > Server types > Web servers > web_server_name > Intelligent Management, and clear the Enable check box. Click OK.

  2. Generate the plug-in configuration file. In the console, click Servers > Server types > Web servers . Select the web server and click Generate plug-in.

  3. Propagate the plug-in. In the console, click Servers > Server types > Web servers . Select the web server and click Propagate plug-in.
