Log in to the machine that has Web Server configured as the load balancer plug-in. You will create a listener for each instance of the cluster and the contexts roots for Access manager.
Locate the loadbalancer.xml file.
Add the listeners to the file. For example:
 <instance  name="instance1" enabled="true" disable-timeout-in-minutes="60" 
listeners="http://host-server1.expamle.com.com:8182"/>
        <instance  name="instance2" enabled="true" disable-timeout-in-minutes="60" 
listeners="http://server1.example.com:8182"/>
        <instance  name="instance3" enabled="true" disable-timeout-in-minutes="60" 
listeners="http://server2.exapmle.com:8182"/>
        <web-module context-root="/amserver" enabled="true" disable-timeout-in-minutes="60" 
error-url="sun-http-lberror.html" />
        <web-module context-root="/ampassword" enabled="true" disable-timeout-in-minutes="60"
error-url="sun-http-lberror.html" />
        <web-module context-root="/amcommon" enabled="true" disable-timeout-in-minutes="60" 
error-url="sun-http-lberror.html" />
In loadbalancer.xml, change property name to the following:
<property name="response-timeout-in-seconds" value="120"/>
Restart the Web Server.
