What Do You Need?

To create and configure machines in the domain by using the administration console, perform the following steps:

1. If the administration server of the domain is not already running, start it.
   1. Open a Terminal window and navigate to the domain directory. In this tutorial, the domain directory is /scratch/u01/app/fmw/user_projects/domains/mydomain.
   2. In the domain directory, enter the following command: ./startWebLogic.sh

      

   3. At the prompt, enter the credentials of the domain administrator. In this tutorial, the username is weblogic and the password is welcome1.
      Note: The password is not displayed.

      

      
      

      Wait until the administration server is running before continuing.

2. If any of the managed servers of the domain are running, shut them down. (You cannot change the machine of a running server.)
   
   1. Open a web browser and enter the following URL for the administration console: http://hostname:port/console
      In this tutorial, the URL is http://<ip_address>:7001/console. Replace <ip_address> with the host name or IP address of your administration server.
   2. On the Welcome screen, log in with the username and password that you entered to start the administration server.

      

   3. In the administration console, under Domain Structure, expand Environment, and then click Servers.

      

   4. On the Control tab, under Summary of Servers, select the check box for each running managed server, and then select Force Shutdown Now from the Shutdown list.

      

   5. At the prompt, click Yes, refresh the browser, and ensure that all managed servers show the SHUTDOWN state.

      

3. Creating a machine is a change to the domain's configuration, so you must first locked the configuration. In the Change Center, click Lock & Edit.

   

4. Under Domain Structure, expand Environment, and then click Machines.

   

5. On the right, above the Machines table, click New to open the Create a New Machine wizard.

   

6. On the Machine Identity page, enter machine2 for the name, select Other for the machine OS, and then click Next.
   Note: In this tutorial, WebLogic Server is running on Linux. Although Linux is a UNIX-based operating system, you don’t need the UNIX-specific machine settings for this tutorial. Therefore, select the simpler Other option.

   

7. On the Node Manager Properties page, select Plain for the Node Manager type, enter the host name or IP address of the machine, enter a port, and then click Finish.
   In this tutorial, the IP address is entered for the Listen Address, and 5557 is entered for the Listen Port.

   

8. In the Change Center, click Activate Changes.

   

   The following message is displayed: "All changes have been activated. No restarts are necessary."

9. To update the new machine, lock the configuration again.

   

10. In the Machines table, click machine2.

    

11. Under " Settings for machine2," click the Configuration tab and the Servers subtab.

    

12. Above the Servers table, click Add.

    

13. On the Add a Server to Machine page, ensure that Select an existing server, and associate it with this machine is selected, select server2, and then click Finish.

    

14. Change the settings of machine1.
    1. In the Machines table, click machine1.

       

    2. Under "Settings for machine1," click the Configuration tab and the Node Manager subtab.

       

    3. Select Plain for the Node Manager type, ensure that the machine's host name or IP address is correct for the Listen Address, ensure that Listen Port is 5556, and then click Save.

       

    4. Click the Configuration tab and the Servers subtab and review the servers for machine1.

       

       
       

       In the Servers table, you can see that the other servers are still assigned to machine1.

       

15. In the Change Center, click Activate Changes.

    

To restart the managed servers, perform the following steps:

1. Run the managed server start script.
   1. Open a Terminal window and navigate to the bin directory under your domain directory. In this tutorial, the domain directory is /scratch/u01/app/fmw/user_projects/domains/mydomain.
      
      Enter the following command: startManagedWebLogic.sh. This command takes two arguments:
      
      • The name of the managed server that you want to start
      • The URL of the administration server
      
      In this tutorial, those arguments are:
      
      • server1
      • http://<hostname>:7001
        Note: Replace <hostname> with the host name or IP address of your administration server.

        

   2. At the prompt, enter the administrator username and password.
      Note:The password is not displayed.

      

2. Wait for the following message: The server started in RUNNING mode. This message means that the server is up and running.
