WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

Installation and configuration
To set up an environment as illustrated in Figure 5-2 on page 141 the following
installation and configuration steps are required:
System A
Perform the following steps to install and configure System A.
1. Install and configure a supported Web server.
2. Install and configure the WebSphere Application Server Plug-in for the Web
server.
System B
Perform the following steps to install and configure System B.
1. Install WebSphere Application Server V7.0
2. Create an application server profile using the following profile template:
/profileTemplates/default
3. Create a Web server definition through the Integrated Solutions Console or
through the wsadmin scripting interface.
Note: The Web server definition is used by the application server to
generate the plug-in configuration file. In a stand-alone topology, only one
Web server can be defined to the configuration and it must be an
unmanaged Web server.
5.3.2 Vertical scaling topology
Vertical scaling (depicted in Figure 5-3 on page 144) refers to configuring
multiple application servers on a single machine or LPAR and creating a cluster
of associated application servers all hosting the same applications. All members
of the application server appear as one logical unit serving the applications
deployed to the cluster.
Keep in mind that a WebSphere Application Server cluster can only be
implemented with the Network Deployment or the z/OS packages.
