Administer application servers

 

Overview

An application server provides the runtime environment in which you deploy and run the applications.

For information on starting and stopping application servers, see Start and stop application servers.

If you want to configure individual application servers to support different language environments, see Configure application servers for other language environments.

 

Configure application servers

To create an application server with the administrative console, follow these steps:

  1. Start the administrative console.

  2. Expand...

    Servers | Application Servers | New

  3. Specify a name for the application server. You can also specify optional properties:

    • If you are running Network Deployment, you can create the application server on any node in the Network Deployment cell.

    • By default, when a new application server is created, WebSphere Application Server assigns unique HTTP ports to the new server. It is recommended that you generate unique ports for you new application server.

    • You can create the new server based on an existing application server or based on the default application server template.

  4. Click Next.

  5. Review the summary of the new application server's configuration, and click Finish.

  6. Save the configuration.

After you create the application server, configure it to run the applications.

  1. Expand...

    Servers | Application Servers

  2. On the Application Servers page, click the name of the application server that you want to modify.

  3. On the application server's detail page, you can configure additional properties on the Configuration tab. If the application server is running, you can also configure properties on the Runtime tab.

    In the base WebSphere Application Server product, the Runtime tab is available for only the primary application server. If you create additional application servers, you cannot configure runtime propertes for them from the administrative console running in the primary application server. The primary application server is the application server which is running the administrative console application and from which you created additional application servers. To modify runtime settings for a secondary application server, you can use the wsadmin administrative tool.

 

Modify application servers

To modify an application server's configuration, follow these steps:

  1. Start the administrative console.

  2. Expand...

    Servers | Application Servers

  3. On the Application Servers page, click the name of the application server that you want to modify.

  4. Make the changes.

  5. Click OK.

  6. Save the configuration.

 

Remove application servers

You can remove application servers that you create on the node after you create the instance. You cannot remove the primary application server, which is created when you create the instance.

To remove an application server, follow these steps:

  1. Stop the application server if it is running.

  2. To verify that the application server job has ended, run this command on an OS/400 command line: 
    WRKACTJOB SBS(QEJBAS5)
    Verify that the application server job no longer exists in the subsystem.

  3. Expand...

    Servers | Application Servers

  4. On the Application Servers page, select the checkbox for the application or applications that you want to remove.

  5. Click Delete.

  6. To confirm that you want to delete the application server, click OK.

  7. Save the configuration.
