(Dist) Add assisted lifecycle middleware servers (deprecated)

By configuring assisted lifecycle middleware servers, we can manage representations of externally created middleware servers that were created outside of the administrative domain.

Deprecated feature: Assisted and Complete Lifecycle servers have been deprecated in WebSphere Application Server v9.0. Migrate WebSphere Liberty servers to a Liberty Collective configuration. There is no recommended migration action for other server types.depfeat

Read about adding middleware servers to configurations for information about installing the node agent on nodes, and federating those nodes into the configuration.

With assisted lifecycle middleware servers, we can create a representation of the server. The node agent provides the information that Intelligent Management needs to manage these servers. We can configure the following assisted lifecycle middleware server types:

Intelligent Management support for using the following server types is stabilized:

On the administrative console, when we select Servers > All servers > middleware_server> Stop for a middleware server that displays a status of Started, we can intermittently receive an error. The following message is an example of the error:

The server cannot be stopped from this page when this situation occurs.

As a work-around, complete one of the following actions to stop the started middleware server:

After installing the node agent on WAS Community Edition nodes and federate the nodes, middleware discovery can automatically create representations of these servers in the administrative console. We do not need to perform the manual steps to create the representation of the server in the administrative console. We can continue to manage these servers in the WAS Community Edition console. Make any representative changes in the administrative console.


Tasks

  1. Create a representation of the middleware server.

    • If we use wsadmin scripting commands:

      • For Apache Tomcat servers, use createTomCatServer.

      • For BEA WebLogic servers, use createWebLogicServer.

      • For JBoss servers, use createJBossServer.

      • For external WebSphere application server (application servers that run outside the Intelligent Management cell), use createForeignServer.

      • For Liberty profile servers, use createLibertyServer.

    • If we use the administrative console.

      1. Add an existing server.

        In the administrative console, click...

                Servers > Add a server and select Add an existing server.

      2. Select the node on which the middleware server that we are configuring runs.

        The node must be running a node agent. Create a name for the server that is unique among all servers in the cell.

      3. Specify the server template to use for the middleware server.

      4. Click Finish.

      5. Click Save to save the changes to the master configuration.

  2. Perform additional configuration steps for the middleware server, including adjusting the values for the WebSphere variables for each server type and configuring server operations to stop and start the servers:

    • For Apache Tomcat servers, read about configuring Apache Tomcat servers.

    • For BEA WebLogic servers, read about configuring BEA WebLogic servers.

    • For JBoss servers, read about configuring JBoss servers.

    • For WAS Community Edition servers, read about configuring assisted life-cycle WAS Community Edition servers.

    • For custom HTTP servers, read about configuring custom HTTP servers.

    • For external WebSphere application server (application servers that run outside the Intelligent Management cell), we can manage previous versions of WebSphere application servers, from Version 5.1 and later. See configuring external WebSphere application servers.

    • For Liberty profile servers, read about configuring Liberty servers.

    The WebSphere variables define settings for the middleware server such as the installation location and vary depending on the middleware server type. By editing the server start and stop operations, we can specify the username and password required to start and stop the servers in the middleware server.

  3. Start the middleware server.

    • For Apache Tomcat servers, BEA WebLogic servers, JBoss servers, Liberty profile servers, and external WebSphere application servers, use the startMiddlewareServer command.

    • In the administrative console, click...

              Servers > All servers. Select the server to start and click Start.

    The start server operation that is defined for the server runs.

    If the node agent and the server are stopped at the same time, the last known status of the server is reported. Because the last known status is reported as started, the on-demand router (ODR) tries to route to the server.


What to do next

Create a middleware server template based on your configured server. After creating a middleware server template, we can create additional servers using the template, which creates servers with the same settings as the original server.

To easily manage groups of existing servers to host an application, configure dynamic clusters. By configuring a dynamic cluster, the product can adjust the number of running servers to meet the application service policy. For assisted lifecycle middleware servers, you group together the representations that we created. These servers must have the same applications installed.

The logs and trace views in the administrative console are not supported for assisted lifecycle middleware servers. For Apache Tomcat servers, BEA WebLogic servers, JBoss servers, Liberty profile servers, and external WebSphere application servers (application servers that run outside the Intelligent Management cell), we can view logs for these middleware servers on the machines that host them. For other assisted lifecycle middleware servers, configure the external log viewing service to view the log files in the administrative console.
