out of these possible options, the only protocol that supports two-phase commit transactional coordination for eci flows is the external cics interface (exci).
在这些可能的选项之外,唯一支持eci流程的两阶段提交事务协调的协议是externalcicsinterface(exci)。
if it detects that all the resources involved in the transaction are the same, it can skip the two-phase commit and let the resource manager handle the transaction by itself.
如果它检测出所有与事务相关的资源都一样,它可以跳过两阶段提交并让资源管理器自己来处理事务。
this is because the ejb container cannot commit a one-phase commit resource together with two-phase commit resources in a global transaction.
这是因为在全局事务中ejb容器不能同时提交单阶段提交资源和两阶段提交资源。
some configurations, such as those with only one database resource, do not require the full data integrity that is provided by the two-phase commit protocol of the xa interface.
有些配置(如只有一个数据库资源的那些配置)不需要xa接口的两阶提交协议提供的数据完整性。
at that point it will use a two-phase commit to ensure it can actually acquire data from each source.
这样,它将使用两阶段提交来保证确实从每个源获取到了数据。
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。
the most common commit protocol is the two-phase commit protocol. as it is named, the two-phase commit protocol involves two phases
最常见的提交协议是两阶段提交协议。
an essential part of all transactional standards is the two-phase commit process.
所有事务标準的一个基本部分是两阶段提交流程。
the updates only become hardened once the transaction manager initiates the two-phase commit process.
只有在事务管理器启动两阶段提交进程时,更新才会变得确定。

联邦语句的两阶段提交
instead, use two-phase commit transactions.
作为替代的方式,应该使用两阶段提交事务。
local (default): this setting is required when a component implementation is not capable of participating in a two-phase commit protocol. things to note in a local transaction are
local(默认):当组件实现不能够遵循一个两阶段提交协议时,需要这一设置。
this is particularly true when transactions are widely distributed to business partner systems that may or may not be capable of participating in a standard, two-phase commit transaction.
当事务广泛地分布在也许能或也许不能参与标準的、两阶段提交事务的商业伙伴系统时是尤其正确的。
in this article, gang focuses on xa distributed transactions and on the inner workings of the two-phase commit protocol.
在本文当中,gang 将集中探讨xa分布式事务及两阶段确认协议的内部工作。
are there any circumstances when a one-phase commit protocol provides benefits over a two-phase commit protocol?
是否存在单阶段提交协议比两阶段提交协议更有好处的情况?
a transaction participant that is called during two-phase commit and which can influence the outcome of the transaction.
在两阶段提交期间调用的事务参与者,它能影响事务的结果。
what happens if there is a network connection failure during two-phase commit processing?
如果在两阶段提交处理过程中出现网络连接故障,会发生什么情况?
if your application needs to access multiple resources as part of the same operation, you need two-phase commit transactions.
如果您的应用程序在同一个操作中需要访问多种资源,您就要使用两阶段提交事务。
xa transaction -- a resource adapter that can participate fully in a two-phase commit process, and which can influence the outcome of the global transaction.
xa事务——可以完全参与两阶段提交进程的资源适配器,该资源适配器可以影响全局事务的结果。
