    • An extensible process design provides an ability to dynamically inject changes into a running process instance, such as a BPEL instance. Using a combination of BPEL, rules and events, processes can be designed to allow flexibility in terms of adding new activities, removing or skipping activities and adding dependent activities. These changes do not require redeployment of the orchestration process and can affect the behavior of in-flight process instances. The extensible process design includes a main orchestration process, a set of task execution processes and a set of generic trigger processes. The design also includes a set of rules evaluated during execution of the tasks of the orchestration process. The design can further include three types of events: an initiate process event, a pre-task execution event and a post-task execution event. These events and rules can be used to alter the behavior of the main orchestration process at runtime.
    • 可扩展过程设计提供了将更改动态注入正在运行的流程实例(如BPEL实例)的功能。 使用BPEL,规则和事件的组合,可以设计流程以允许在添加新活动,删除或跳过活动以及添加依赖活动方面的灵活性。 这些更改不需要重新部署编排过程,并且可能影响飞行中流程实例的行为。 可扩展过程设计包括主要的编排过程,一组任务执行过程和一组通用触发过程。 该设计还包括在执行编排过程任务期间评估的一组规则。 该设计可以进一步包括三种类型的事件:启动过程事件,前任务执行事件和后任务执行事件。 这些事件和规则可用于在运行时改变主要业务流程的行为。
