Creating application servers

During the installation process, the product creates a default application server, named server1. Most installations require several application servers to handle the application serving needs of their production environment. You can use the command-line tool or the administrative console to create additional application servers.

Before you begin

Determine if you want to use the application server that you are creating as part of a cluster. If this application server is going to be part of a cluster, you must use the Create a new cluster wizard instead of the Create a new application server wizard to create this application server. The topic Adding members to a cluster describes how to use the Create a new cluster wizard.

About this task

To create a new application server that is not part of a cluster, you can either use the createApplicationServer, createWebServer, or createGenericServer wsadmin command, or you can use the administrative console.

If you are migrating from a previous version of the product, you can upgrade a portion of the nodes in a cell, while leaving others at the previous product level. This means that, for a period of time, you might be managing servers that are running at two different release levels in the same cell. However, when you create a new server definition, you must use a server configuration template, and that template must be created from a server instance that matches the version of the node for which you are creating the server.

There are no restrictions on what you can do with the servers running on the more current release level.

Avoid trouble Avoid trouble: If you use additional servers with unique ports, WebSphere® Application Server does not automatically configure the virtual host for the server. Specifically, WebSphere Application Server does not automatically add the host alias ports to a virtual host. However, you can use the administrative console to add a new host alias for each of the ports that are used by the new server. For more information, see the documentation about configuring virtual hosts.gotcha

Complete the following steps if you want to use the administrative console to create a new application server that is not part of a cluster.

Procedure

  1. In the administrative console, click Servers > Server Types > WebSphere application servers > New .

    The Create a new application server wizard starts.

  2. Select a node for the application server.
  3. Enter a name for the application server. The name must be unique within the node.
  4. Click Next.
  5. Select a server template for the new server.

    You can use a default application server template for your new server, or you can use the template that is optimized for development uses. The new application server inherits all of the configuration settings of the template server.

  6. Click Next.

    By default, this option is enabled. If you select this option, then you might need to update the alias list for the virtual host that you plan to use with this server to contain these new port values. If you deselect this option, then ensure that the default port values do not conflict with other servers on the same physical machine.

  7. Select Generate unique HTTP ports if you want the wizard to generate unique ports for the application server.
  8. Click Next. Review the settings for the new server.
  9. If you want to change any of the settings, click Previous until you return to a page where you can change that setting.
  10. Click Finish when you do not want to make any additional changes.
  11. Click Review, select Synchronize changes with nodes, and then click Save to save your changes.

Results

The new application server is in the list of servers on the administrative console Application servers page.

What to do next

This newly created application server is configured with default settings that are not displayed when you run the Create New Application Server wizard.
