摘要： A transaction management engine, such as a business process management (BPM) engine, can allow an application to define transaction demarcations in order to ensure that portions of a workflow are processed atomically. In one such system, a JMS message is queued to the workflow as part of an existing transaction. If that transaction commits, the queued JMS message ensures that the workflow will be invoked in a new transaction that allows the workflow to perform the next unit of work in the newly initiated transaction. When the unit of work is completed, the workflow queues another JMS message. If this transaction commits, the transaction ensures the unit of work has executed in a transaction. When the workflow is invoked again due to the second JMS message, the workflow can continue its operation in a different transaction.
摘要翻译：事务管理引擎（如业务流程管理（BPM）引擎）可以允许应用程序定义事务划分，以确保工作流的部分原子处理。在一个这样的系统中，JMS消息作为现有事务的一部分排队到工作流。如果该事务提交，则排队的JMS消息确保在新事务中调用工作流，从而允许工作流在新启动的事务中执行下一个工作单元。当工作单元完成时，工作流排队另一个JMS消息。如果此事务提交，则事务确保工作单元在事务中执行。当由于第二个JMS消息再次调用工作流时，工作流可以在不同的事务中继续其操作。

摘要： A Registration protocol is used in transaction processing for normal operations. If an error occurs, the system reverts to a Full Broadcast protocol. The Registration Protocol reduces the number of messages that are sent among CPUs in a cluster thereby permitting performance improvements in the system. The Registration Protocol has Begin, DP2 Check, Phase 1 Flush and Phase 2 (lock release) phases just as does the Full Broadcast Protocol, thereby permitting the Full Broadcast protocol to step in at any phase after an error is detected.
