    • Disclosed is a technique for system recovery. Information identifying one or more work requests is retrieved, along with an order of the work requests, for a business process. If the business process is non-transactional, an in-memory structure is created for the business process, a recovery stub is created for each work request, and the recovery stub for each work request is placed into the in-memory structure based on the order. Also disclosed is a technique for system recovery in which, if the business process is transactional, an in-memory structure is created for the business process, a recovery stub is created for each work request that indicates that rollback is to be performed, and the recovery stub is placed for each work request into the in-memory structure based on the order. Furthermore, an alternative technique for system recovery is disclosed in which, if the business process is transactional, a rollback is performed for each work request, and an in-memory structure is created for the business process. New work requests may be accepted in the in-memory structure after processing each of the one or more identified work requests for both transactional and non-transactional business processes.
    • 公开了一种用于系统恢复的技术。 检索识别一个或多个工作请求的信息以及业务流程的工作请求的顺序。 如果业务流程是非事务性的,则为业务流程创建内存中结构,为每个工作请求创建一个恢复存根,并且每个工作请求的恢复存根将基于 订购。 还公开了一种用于系统恢复的技术,其中如果业务流程是事务性的,则为业务流程创建内存中结构,为指示要执行回滚的每个工作请求创建恢复存根,并且 恢复存根根据顺序将每个工作请求放入内存中结构。 此外,公开了用于系统恢复的替代技术,其中如果业务流程是事务性的,则对每个工作请求执行回滚,并且为业务流程创建内存中结构。 在处理事务处理和非事务性事务处理的一个或多个所识别的工作请求中的每一个之后,可以在内存中结构中接受新的工作请求。
