To Install the Load Balancer on Node 3

1. Install the Load Balancer plugin on Node 3 that is provided with Application Server 8.2. Select Web Server as a component to install with the Load Balancer plugin.

2. In a text editor, open the loadbalancer.xml file on Node 3.

   This file is located in the WebServer_base/SUNWwbsvr7/https-Node3/config directory.

3. Edit the file so that the Load Balancer balances the load between the two Access Manager instances.

   Edit the listeners with the appropriate values.

   A sample loadbalancer.xml which balances the load on Portal Server and Access Manager instances on Node 1 and Node 2 is as follows:

   <!DOCTYPE loadbalancer PUBLIC "-//Sun Microsystems Inc.//DTD Sun ONE Application Server 7.1// EN" "sun-loadbalancer_1_1.dtd"> <loadbalancer> <cluster name="cluster1"> <!-- Configure the listeners as space seperated URLs like listeners="http://host:port https://host:port" For example: <instance name="instance1" enabled="true" disable-timeout-in-minutes="60" listeners="http://localhost:80 https://localhost:443"/> --> <instance name="instance1" enabled="true" disable-timeout-in-minutes="60" listeners="http://node1.domain-name:8080"/> <instance name="instance2" enabled="true" disable-timeout-in-minutes="60" listeners="http://node2.domain-name:8080"/> <web-module context-root="/portal" enabled="true" disable-timeout-in-minutes="60" error-url="sun-http-lberror.html" /> <web-module context-root="/psconsole" enabled="true" disable-timeout-in-minutes="60" error-url="sun-http-lberror.html" /> <web-module context-root="/amserver" enabled="true" disable-timeout-in-minutes="60" error-url="sun-http-lberror.html" /> <web-module context-root="/amconsole" 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" /> <web-module context-root="/" enabled="true" disable-timeout-in-minutes="60" error-url="sun-http-lberror.html" /> <health-checker url="/" interval-in-seconds="10" timeout-in-seconds="30" /> </cluster> <property name="reload-poll-interval-in-seconds" value="60"/> <property name="response-timeout-in-seconds" value="30"/> <property name="https-routing" value="true"/> <property name="require-monitor-data" value="false"/> <property name="active-healthcheck-enabled" value="false"/> <property name="number-healthcheck-retries" value="3"/> <property name="rewrite-location" value="true"/> </loadbalancer>

4. Start the Web Server.

5. On Node 1 and Node 2, start Access Manager, Directory Server, and Application Server .
