The portal instances should be clustered and HADB should be installed.
Undeploy the portal.war from the Application Server 8.2 DAS (administration server), and add the <distributable/> tag in the WEB-INF/web.xml of portal.war. Refer to the sample web.xml file displayed below:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN " "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name>Sun Java Enterprise System Portal Server Desktop Web Application</ display-name> <description>Provides a user customizable interface for content that is aggregat ed from Portlet applications</description> <distributable/> <context-param> <param-name>desktop.configContextClassName</param-name> <param-value>com.sun.portal.desktop.context.PropertiesConfigContext</param-value> |
Add the same <distributable/> tag to the web.xml of the portlet.war which is used for storing session variable.
Ensure that the Availability option is selected for both portal.war and the portlet.war files.
