Business Process Choreographer overview

Describes the facilities provided by the Business Flow Manager, Human Task Manager, and Business Process Archive Manager.

Business Process Choreographer is an enterprise workflow engine that supports both BPEL processes and human tasks in a WebSphere Application Server environment. These constructs can be used to orchestrate services as well as integrate activities that involve people in business processes. Business Process Choreographer manages the lifecycle of BPEL processes and human tasks, navigates through the associated model, and invokes the appropriate services.

Business Process Choreographer provides the following facilities:

• Support for BPEL processes and human tasks.

  Allows you to model your business process using the Web Services Business Process Execution Language (WS-BPEL, abbreviated to BPEL). With human tasks, you can use the Task Execution Language (TEL) to model activities that involve people. Both BPEL processes and human tasks are exposed as services in a SOA or Service Component Architecture (SCA); they also support simple data objects and business objects.

• Application programming interfaces for developing customized applications for interacting with BPEL processes and human tasks.
• Human workflow widgets as part of Business Space.

  These widgets allow you to manage work, create tasks for other people, and initiate services and processes.

• Business Process Choreographer Explorer.

  This web application allows you to administer BPEL processes and human tasks.

• Business Process Archive Manager.

  When configured, this provides a separate database, to which completed process instances and human tasks can be moved by running an administrative script. This can help to maintain the performance of your Business Process Choreographer database. An API is also available so that you can create your own client that can work with archived instances.

  The Business Process Archive Explorer is a web application that allows users to browse or delete instances that have been moved to the archive database. See BPEL process archiving overview.

• By default, new Business Process Choreographer configurations benefit from the performance improvements resulting from using shared work items.

• To monitor and report on BPEL processes, use IBM Business Monitor.
