A CICS program that issues a SYNCPOINT command (with or without the rollback option) cannot be subordinate to another transaction manager, and thus cannot be part of an extended or global transaction.
发出SYNCPOINT命令(带有或不带有回滚选项)的CICS程序不能从属于另一个事务管理器，因此它也不能成为扩展或全局事务的一部分。
Not only will Client a receive an exception if it tries to roll back the transaction, but Client a cannot take corrective action because the transaction has already been marked for rollback.
客户机a在尝试回滚事务时，不仅会收到一个异常，而且客户机a还不能采取纠正操作，因为事务已经被标记为回滚。
The business process also has a snippet component, which you can use to raise a fault and to demonstrate a global transaction rollback.
业务流程也有一个代码段组件，您可以用它来引发一个故障并演示一个全局事务回滚。
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。
Note that even in the case of a rollback, the callback function must do some cleanup, removing all the records that were part of the transaction from the named memory.
注意，即便是回滚情况，回调函数也必须执行一些清理：从已命名内存删除作为事务一部分的所有记录。
When you rollback to a savepoint set earlier in a transaction, IDS just rolls back all the operations logged by the transaction after the savepoint was set.
当回滚到事务中早先设置的保存点时，IDS将只回滚在设置保存点后由事务记录的所有操作。
Unfortunately, the effect of this characteristic is that a lower-level method that isn't the transaction owner might perform a rollback on exception.
遗憾的是，此特性的效果是，作为非事务拥有者的较低级方法可以对异常执行回滚。
Why does the commit or rollback of a transaction close the result set?
为何事务的提交或回滚关闭结果集？
Conversely, application exceptions under EJB 1.0 automatically caused a transaction rollback under certain circumstances.
反过来说，EJB 1.0下发生的应用程序异常在某种环境下会自动导致一个事务回滚。
Once you are in a transaction, you may use PDO: : commit or PDO: : rollBack to finish it, depending on the success of the code you run during the transaction.
在一个事务中，可以使用PDO：commit或PDO：rollBack来结束该事务，这取决于事务中运行的代码是否成功。
A transaction callback must be defined in the objectgrid.xml to receive transaction commit or rollback events and send it to the JPA layer.
在objectgrid.xml中必须定义事务的回调函数，这样就可以接收事务提交或回滚的事件，并将其发送到JPA层。
The domain class properly has a transaction attribute of MANDATORY because the client is starting the transaction, and the domain model (insertTrade()) is not responsible for rollback.
域类属性有一个事务属性MANDATORY，因为客户机正在启动事务，而域模型（insertTrade()）不负责执行回滚。
Stateful components can be problematic in a web context because of managing cached state for example - many applications break when a rollback occurs because the state isn't tied to the transaction.
由于需要管理缓存着的状态，有状态的组件可能会在Web上下文中出现问题，比如，发生回滚时许多应用都会出问题，因为状态并没有和事务绑定起来。
This means that if the transaction ends with a rollback, the record is removed from the auditTable table.
这意味着如果事务最终回滚，记录将从audittable表中移除。
Hence, both actions need to be within a single transaction with a single outcome: either both actions occur (a commit outcome), or neither action occurs (a rollback outcome).
因此，两个动作需要在具有单个结果的单个事务内：两个动作都发生(提交结果)，或两个动作都不发生(回滚结果)。
Prior to the two-phase commit process, all work performed during the transaction is said to be in-flight, and failure during this period will lead to a rollback of work.
在两阶段提交进程之前，事务过程中执行的所有工作都被认为是“在处理中”，并且在此期间如果失败将会导致工作回滚。
This lets you set, rollback, and release savepoints in a transaction.
它允许您在事务中设置、回滚和释放保存点。
In the case of an error, the transaction logic can specify that the transaction rollback to a savepoint.
在发生错误的情况下，事务逻辑可以指定该事务回滚到某个保存点。
The transaction log is stored as a sequential disk file (or sometimes in a raw partition) and will generally only be written to, not read from, except in the case of rollback or recovery.
事务日志存储为连续的磁盘文件(有时存储在原始分区中)，并且一般只是用于写入而不用于读取，回滚或恢复的情况例外。
Below you have the example how to rollback the transaction branch for a database.
下面的例子展示了如何为数据库回滚事务分支。
First, if a method did not start a transaction, it has no business managing that transaction (for example, marking it for rollback).
首先，如果某个方法没有启动事务，那么它就不需要管理事务（例如，将其标记为回滚）。
So COMMIT and ROLLBACK statements are important building blocks of a transaction implementation.
因此COMMIT和rollback语句是事务实现的重要构建块。
This option specifies whether or not a CICS transaction abend should trigger an automatic rollback of the RRS unit of Recovery and force a back-out of all updates made within the CICS unit of work.
此选项可以指定CICS事务异常终止是否应触发恢复的RRS单元的自动回滚，并强制执行在CICS工作单元中所进行的所有更新的回退。
This illustrates the use of savepoints in a scenario where you would want to rollback just a small part of a transaction.
这演示了在您希望仅回滚事务的一小部分的保存点。
