27.4 Preparing a WebSphere Cluster for the User Application

This section outlines the process for preparing a WebSphere cluster for use with the User Application. This section assumes that you are an experienced user of the WebSphere Application Server (WAS).

  1. Install and configure your WebSphere Application Servers and cluster according to the manufacturer’s instructions.

  2. Install, configure, and deploy the User Application on a WebSphere Application Server.

    For more information about installing and configuring the User Application on a single server, see Section 28.3, Installing on a WebSphere Application Server.

    NOTE:The installer writes the sys-configuration-xmldata.xml file to the directory that you specify during installation.

  3. While performing the steps in Section 28.3.4, Adding User Application Configuration Files and JVM System Properties, you must complete the following additional steps:

    1. Create a new JVM system property for each User Application server in the cluster.

    2. Name the system property com.novell.afw.wf.engine-id where the engine ID is a unique value.

      Each User Application server runs a workflow engine, and each engine requires a unique engine ID.

  4. (Conditional) To use session failover with RBPM, complete the following steps:

    1. In the IBM Admin Console, navigate to Application servers > clustermember1 > Session management > Distributed environment settings > Tuning parameters > Custom tuning parameters.

    2. Specify All session attributes mode, which controls the write content for session failover.

  5. Start the application server, and then access the User Application portal using the context that you specified during deployment.
