Overview

WebSphere Application Server provides you with the capability to create application servers.

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, use the wizard...

Create a new cluster

...instead of the wizard...

Create a new application server

...to create this application server.

To create a new application server, you can use any of the following wsadmin commands...

• createApplicationServer
• createWebServer
• createGenericServer

...or you can use the administrative console.

You can also create a new application server when you add a cluster member to a server cluster.

If you are migrating from a previous version of WebSphere Application Server, you can upgrade a portion of the nodes in a cell, while leaving others at the older 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, use a server configuration template, and that template must be created from a server instance that matches the version of the node on which you are creating a server.

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

You can perform the following steps to create a new application server from the administrative console.

Procedure

1. In the administrative console, click either...

   Servers | Application servers | New

   ...or...

   Servers | Clusters

   The former starts the Create a new application server wizard.

   The latter starts the Create a new cluster wizard starts and should only be used if the application server is part of a cluster and brings you to the administrative console page where you can either:

   • Click New if this application server is the first member of a new cluster, or

   • Click on the name of an existing cluster to make this application server a new member of that cluster.

   Both options start the Create a new cluster wizard.

2. Select a node for the application server.

3. Type in 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 to perform well for development uses. The new application server inherits all of the configuration settings of the template server.

6. Click Next and then select Generate Unique HTTP Ports if you want the wizard to generate unique ports for the application server.

   By default, this option is enabled. If you select this option, 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, ensure that the default port values do not conflict with other servers on the same physical machine.

7. Click Next. Review the settings for the new server. If you want to change any of the settings, click Previous until you return to a page where you can change that setting. If you do not want to make any changes, click Finish

8. Click Review, select Synchronize changes with Nodes, and then click Save to save your changes.

What to do next

To view all of the configuration settings for this application server in the administrative console, click Servers > Application servers and then click on the name of this application server. If necessary, use this page to change the configuration settings for this server.

You can also set the client.encoding.override JVM argument to UTF-8 if you need to use multiple language encoding support in the administrative console.
