[Version 5.0.2 and later]Planning to use process choreographer

Why and when to perform this task

For each application server that uses process choreographer, you must configure the business process container before installing any enterprise applications that contain processes. Before configuring the business process container, consider the following items:

Steps for this task

  1. To gain more understanding about the process choreographer architecture, refer to the architecture White paper in Target can be accessed only when this topic is linked to the World Wide Web   DeveloperWorks WebSphere .
  2. Decide which database system to use:
    • Cloudscape

      Note: Because Cloudscape Network Server has no XA support, process choreographer can only use the Embedded Cloudscape version that can not be accessed remotely. That is why Cloudscape cannot be used as database system for process choreographer in a distributed environment

    • DB2 UDB for Linux, UNIX, and Windows
    • DB2 for z/OS
    • [Version 5.0.2 and later]Microsoft SQL Server
    • Oracle
    • Sybase Adaptive Server Enterprise; process choreographer uses distributed transactions, so you need to purchase and install the Distributed Transaction Management (DTM) feature for Sybase Adaptive Server Enterprise.
  3. Check the Target can be accessed only when this topic is linked to the World Wide Web   required software levels for the supported database version and Java database connectivity (JDBC) driver.
  4. Decide which machine you want to host the database.
    If the database machine is remote, you need a suitable database client or a type-4 JDBC driver that has XA-support.
  5. If you are not going to create a WebSphere cluster setup, decide whether you want to use the Java Message Service (JMS) API provided by:
    • The messaging service that is embedded in WebSphere application server.
    • A separate WebSphere MQ installation.

    Note: If you intend to use embedded messaging, you must have selected this option when you installed WebSphere Application Server. If you want to use WebSphere MQ messaging, it must be installed before you start configuring the business process container. Embedded messaging is not supported in a cluster setup. Some options for optimizing the performance of WebSphere MQ for process choreographer can only be made before the queue manager is created. For more information about tuning process choreographer, see Tuning interruptible processes .

  6. If you intend to use process choreographer in a WebSphere cluster environment, plan your cluster, as described in Process choreographer scenarios for clustering.
  7. Decide if you want to use the install wizard (recommended) rather than configuring the business process container manually:
