Portal light mode in WPS 7.0

The WebSphere Portal Server 7.0 has a concept of portal light node, this is what the infocenter says "Portal now provides a portal light mode which can improve portal startup time and reduce memory consumption in production environments. When you enable portal light mode, specific portlet applications are not started at portal start up. Instead they are started later by the first standard HTTP request that occurs and renders a portal page with the portlet application on the server. This occurs, for example, when a user accesses the portlet application. The default list of these applications whose initialization is deferred until first use (sometimes called "lazy applications"), contains administrative and sample portlet applications. To benefit from a higher performance improvement, you can adapt the default list of these applications to your needs."

Important Note: WebSphere Portal Server had a concept of enable-develop-mode-startup-performance task for some time now. This configuration task is still there in the WPS 70


You will have to follow these steps to enable portal light mode on your WPS 7.0 environment

• First make sure that the light mode is disabled by executing following command
  
ConfigEngine.sh disable-portal-light-startup-performance -DWasPassword=

  


• Unless you want to change the list of applications to either add or remove one of the applications from the startup list you can execute this config command to disable startup performance
  
ConfigEngine.sh enable-portal-light-startup-performance -DWasPassword=

  


• Startup your portal server

How to customize startup application list

If you want to add or remove application from the server startup list then you can do that by going to /WebSphere/wp_profile/PortalServer/config/StartupPerformance directory and modifying one of the following files

1. wp.base_TargetMapInclList.properties: This file has list of applications which will not be started at the time of server startup, you can add the application name, which you can get from the WAS Admin console to this file to disable its startup

2. wp.base_TargetMapExclList.properties: COntains list of applications that should not be disabled. Make sure that your list of lazy applications does not contain applications that are either required for portal startup or frequently used. Do not add portlet applications to the list that hold portal services or a plug-in for an Eclipse extension point. If you have application that you do not want to disabled then add one line for that application to the wp.base_TargetMapExclList.properties file this is the default list

Important Note: I build and install lot of sample portlets for my blog and as result my server statup performance goes down over period of time. So i run this task frequently to disable some of the sample applications.
