You can install multiple web server adapters on multiple machines or on a single machine

6.7.4 Multiple ServletExec/AS Instances (Multiple Java VMs)
It is possible to configure a web server adapter to forward HTTP requests to more than
one ServletExec/AS instance.
To install multiple ServletExec/AS instances
• Run the ServletExec/AS installer again to install another instance. Remember to
give each instance a unique name and port number during the installation process.
To configure a web server adapter to forward HTTP requests to more than one instance
• Specify the incoming requests to forward using this criteria:
1. The virtual host to which the request is addressed (i.e., “
www.abc.com” or
“
www.xyz.com”)
2. The servlet alias (if any) specified by the request
3. The web application context URL (if any) specified by the request
To configure a web server adapter to forward HTTP requests to more than one instance
based on a virtual host or servlet alias
• Manually edit the web server configuration file.
See the Virtual Servers chapter and/or the Servlet Alias section in the ServletExec User
Guide for detailed instructions.
Note
You can use the ServletExec/AS installer to automatically update a web server
configuration file to cause requests that specify a web application URL context path to
be forwarded to a particular ServletExec/AS instance.
To have requests that specify a web application URL context path forwarded to a
particular instance
1. Run the ServletExec/AS installer and select Install or Update a web server
adapter.
2. Enter the name of a previously installed ServletExec/AS instance when prompted.
3. Specify the web application URL context path when prompted.
See Chapter 3 in the ServletExec User Guide for additional information on configuring
