If the application is not prepared to send the commit of "Phase 2" again the transaction branch will be aborted by a heuristical rollback initiated by the engine.
如果应用程序没有准备重新发送“第 2阶段”的提交，该事务分支将被引擎所启动的试探性回滚中止。
Phase 2, commit: If all of the resources are ready, they all commit — after which the old data is deleted and the transaction can no longer roll back.
第2阶段，提交：如果所有的资源都准备就绪，则全部进行提交——在旧数据删除且事务不再回滚之后进行。

If the client receives an "okay" from the databases the client sends the order to commit the transaction to the databases (Phase 2).

In phase 2 (commit phase), WebSphere transaction manager skips the communication with this resource manager, and it will not disk force or log any activities related to this resource manager.

But there is still an open question mentioned in the section "Introduction into the Two-Phase-Commit protocol". What to do, if "Phase 2" failed for a transaction branch?
但是“两阶段提交协议简介”小节中提到仍然存在一个问题，那就是如果第2阶段中一个事务分支发生故障，该怎么办呢？
If phase zero succeeds, the coordinator starts the 2-phase-commit cycle.
如果阶段0成功，协调器将开始两阶段提交循环。
"But", a you might ask, "what happens if an error occurs during Phase 2 of the Two-Phase-Commit protocol?"
“但是”，您或许会问，“如果在两阶段提交(Two - Phase - Commit)协议的第2阶段中出现错误，又将发生什么事情呢？”
Before initiating the 2-phase-commit cycle, the coordinator calls the phase zero participant service of Appl2.
在初始化两阶段提交循环之前，协调器调用Appl2的阶段0参与服务。
DB is the database node. It receives updates of the applications and therefore registers as a participant for the 2-phase-commit protocol.
DB是数据库节点，它负责接收应用程序的更新，因此它作为一个参与者来注册两阶段提交协议。
Coordinator is the WS-transaction coordinator node. It exposes the coordinator services of the completion, phase zero and 2-phase-commit protocols, C-c, C-pz, and C-2pc.
Coordinator是一个WS - transaction协调节点，它提供如下协调服务：完成协议、阶段0协议、两阶段提交协议、c - c、c -pz、和c - 2pc。
To make this happen, the 2-phase-commit protocol was invented (see Principles of Distributed Database systems in Resources) and is also implemented in various systems.
为确保这一点，两步提交协议(请参阅参考资料中的分布式数据库原理)被提出且在各种系统中实现。
It is designed to work with existing mainframe tools and application infrastructure, and offers enterprise-ready 2-phase commit, transactional throughputs, and seamless integration.
