How to map an application to JVMs or web servers in WebSphere

Mapping an application to JVMs or web servers lets you control what servers will be able to produce the application.

  1. In the left panel of the WebSphere admin console, expand Applications and select All applications.
  2. Select the application that you want to map.
  3. Select Manage modules.

In this example, the Beta application is mapped to server01 is node02 in cell was1Cell01.

 

This is a very simple configuration, where the application is running on a single application server.

 


One web server / one JVM

In this example, the Beta application is running on both server01 (the JVM) and IHS (the web server).

 

This is a fairly common for applications that are not mission critical. In this example, the web server is probably configured to produce the applications running on the JVM.

 


One web server / two JVMs

In this example, the Beta application is running on cluster 1 (two JVMs) and IHS (one web server).

 

This introduces some high availability capabilities. If app server 1 goes down, the application will still be able to be produces by app server 2.
