Solaris: Configuring developer mode

Use developer mode to improve startup performance, and to configure IBM WebSphere Portal for development. Developer mode is for a development environment only. Do not use the developer mode in a production environment. We can also run the optimize-derby-database task to improve the Derby database performance.

Install WebSphere Portal.

This task modifies the following components:

    JVM

    The JVM is switched to development mode. This setting is a WebSphere Application Server specific setting independent of WebSphere Portal. The initial heap size is set to 768 MB to reduce the amount of garbage collection during startup.

    Portlets

    Portlets and web applications are activated on first access and not at the startup. However, some of the portlets and applications are required at startup. Create a white list, which contains the list of applications required at startup.

    To add applications to the white list, modify...

      WP_PROFILE/PortalServer/config/StartupPerformance/wp.base_TargetMapExclList.properties

    Add a line such as App_name, where App_name is the name of the application. To get a list of available applications...

  1. Open a command prompt.

  2. Stop the WebSphere_Portal server..

  3. Change to the WP_PROFILE/ConfigEngine.

  4. Run the ./ConfigEngine.sh optimize-derby-database task to improve the performance of the Derby database.

    This task is appropriate only in a demonstration or development environment that is not configured to use WCM. We can also run the optimize-derby-database task after large data changes in the database.

  5. Start the WebSphere_Portal server.

  6. Run...

      ConfigEngine.sh enable-develop-mode-startup-performance

  7. Restart the WebSphere_Portal server to propagate the change.

  8. Prepare the remote web server for the developer mode.


What to do next

To revert to a production server.

    ./ConfigEngine.sh disable-develop-mode-startup-performance -DWasPassword=foo

Restart the WebSphere_Portal server to propagate the change.

We can run the disable-develop-mode-startup-performance task for the following scenarios:

  • When we are done developing the portal and portlets.

  • If the development settings are not adequate for a special development situation.

  • When we cannot re-create a problem on the development server.
