WebSphere Application Server provides you with the capability to
create application servers.
About this task
To create a new application server, 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 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. In this mixed environment, there are restrictions on what you can
do with the servers that are at the older release level:
- You can only create new server definitions on nodes that are running on
the current release level.
- 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 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
- In the administrative console, click Servers
> Application servers > New.
- Select a node for the application server.
- Type in a name for the application server. The name must be unique
within the node.
- Select a server template for the new server.
The new application server inherits all of the configuration settings
of the template server.
- Select whether you want unique ports generated
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.
- If you use an existing application server
as the template for this server, select whether to map applications from the
existing server to the new server. By default, this option is disabled.
Results
The new application server appears
in the list of servers on the administrative console Application servers page.
What to do next
This newly created application server
is configured with many default settings that do not display when you run
the Create New Application Server wizard.
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.
