有保证的交付和逻辑工作单元。
对话相当于逻辑工作单元。
操作：代表单个逻辑工作单元(LUW)的事务。
Operations: Transactions that represent single logical units of work (LUWs).
事务是一个逻辑工作单元。
Transaction-确定组件处理执行的逻辑工作单元。
Transaction - Determines the logical unit of work that the component's processing executes.
在CICSTG的术语中，这称为扩展的逻辑工作单元(图5)。
Within the terms of the CICS TG, this is referred to as an extended logical unit of work (Figure 5).
如果在逻辑工作单元(LUW)中维护一个数据库活动，那么这一技巧将非常有用。
This technique works fine if you have a single database maintenance activity within the logical unit of work (LUW).
事务是必须以单个单元(常被称为逻辑工作单元)的形式执行的一组操作。
A transaction is a set of operations that must be executed as a single unit, which is often called a logical unit of work.
此操作集是一个不可分割的工作单元，并且在一些上下文中又称为逻辑工作单元。
This set of operations is an indivisible unit of work, and in some contexts, is also called a logical unit of work. Transactions provide what are known as the ACID properties
不同信息源的读写访问(特别在对逻辑工作单元进行协调时)将受到供应商特定的支持的约束。
Read-write access to different information sources - in particular when coordinating a logical unit of work - is constrained by the vendor-specific support.
支持对此集成视图的写访问时，联合服务器必须将各个源中的数据操作同步到逻辑工作单元中。
When supporting write access to this integrated view, the federation server must synchronize the manipulation of data in the various sources into a logical unit of work.
否则，它将在事务上下文之外运行，并假设它是惟一一个在逻辑工作单元（LUW）内得到调用的方法。
Otherwise it will run without a transaction context, with the assumption that it is the only method being invoked within the logical unit of work (LUW).
这两步都必须处理为一个逻辑工作单元(即事务)，其中任何一个服务的失败都会向用户发送失败的信息。
Both steps have to be processed as a logical unit of work, and failure in one of the services will result in a failure message to the user.
否则，它将在没有事务上下文的情况下运行，这需要假设它是在逻辑工作单元(LUW)中惟一调用的方法。
Otherwise, it will run without a transaction context, with the assumption that it is the only method being invoked within the logical unit of work (LUW).
该任务本身由多个可恢复的工作单元（也被称为逻辑工作单元）组成，这些工作单元通过同步点区分。
This CICS task can itself be composed of multiple recoverable units-of-work (also known as logical units of work) demarcated by synchronization points (syncpoints).
当使用requires_new属性的几个方法通过服务间通信或编排在同一逻辑工作单元内调用时，该属性就会出现问题。
Problems occur with the REQUIRES_NEW attribute when methods using it are invoked within the same logical unit of work via inter-service communication or through orchestration.
有时，应用程序是使用细粒度的api层编写的，这需要客户端向api层发起多个调用才能实现单个逻辑工作单元(LUW)。
Sometimes applications are written with a fine-grained API layer, requiring the client to make multiple calls to the API layer for a single logical unit of work (LUW).
服务合成(service composition)是相当复杂的，而且常常涉及到事务、工作单元边界、错误处理、安全性与证书分发、以及业务逻辑聚合等方面的问题。
Service composition is highly complex and often includes transactions, unit-of-work boundaries, error handling, security and propagation of credentials, and aggregation of business logic.
