SQL分布式事务涉及的会话并不获取可以传递给另一个会话的事务对象，从而也不能将其显式登记在分布式事务中。
The sessions involved in Transact-SQL distributed transactions do not get a transaction object they can pass to another session for it to explicitly enlist in the distributed transaction.

每次事务修改的对象数量越少就意味着会有更多数据库提交，正如4.5节所述每次提交都会带来磁盘相关的开销。
A smaller number of changed objects per transaction mean more commits to your database, each of which incurs some disk-related overhead as mentioned in Section 4.5.
通过将事务上下文作为线程的一部分进行传递，以允许多个合作对象参与单个事务。

These objects will be used with the client to authenticate with the account in all future transactions.
为了应对可能的这种情况，如果在此事务策略中使用对象关系映射(ORM)框架，则应确保使用了版本验证功能。
To deal with this possibility, make sure you use versioning if you are using an object-relational mapping (ORM) framework with this transaction strategy.
这时，与事务范围相关联的所有对象被自动释放回它们的池。
At that point, all objects bound to the transaction scope are automatically released back to their pools.
存根和骨架对象还负责开始和提交容器管理的事务。
The stub and skeleton objects also take care of beginning and committing container-managed transactions.
实体管理层负责实体管理，并确保容器内该对象的事务完整性。
The entity management layer is responsible for entity management and ensuring the transaction integrity of that object within the container.
例如，第一个短事务使用只读查询来具体化对象，这让您可以在不打开事务就显示对象。
For example, the first short transaction materializes objects using a read-only query, which lets you display the objects without leaving the transaction open.
使用OTS代替创建一个新对象事务协议遵循了现有标准，并使J2EE和CORBA能够互相兼容。
Using OTS instead of inventing a new object transaction protocol builds upon existing standards and opens the way for compatibility between J2EE and CORBA components.
DB 2在事务日志中记录了数据库对象的所有操作或修改。
DB2 keeps a record of all operations or changes made to the database objects in transactional logs.
将事务性语义告知面向对象的组件要求对TPM模型进行扩展—在这个模型中事务是按照事务性对象的调用方法定义的。
Imparting transactional semantics to object-oriented components required an extension of the TPM model, in which transactions are instead defined in terms of invoking methods on transactional objects.
当线程经过合作对象时，事务管理程序使用线程的事务上下文来执行所有的工作。
As the thread passes through the collaborating objects, the transaction manager USES the thread's transaction context to perform all work.
这些线程通常都是轻量级的，用于执行缓存清理和对象清理之类的事务。
They are traditionally lightweight and used for executing tasks such as cache cleanup and object cleanup.
除长期执行的事务以外，只有少数业务对象会受事务影响。
Only a few business objects are affected by most transactions, except for long-living transactions.
脏检查用于验证对象在长事务期间没有被修改。
Dirty checking is used to verify that an object has not been modified during a long transaction.
在整个事务处理过程中，作为事务上下文对象传递控制对象。
Control object, as a transaction context object, is passed through the whole transaction process from beginning to the end.
这是事务处理的主要陷阱之一：基于 ORM 的框架需要一个事务来触发对象缓存与数据库之间的同步。
This is one of the first major pitfalls of transaction processing: ORM-based frameworks require a transaction in order to trigger the synchronization between the object cache and the database.
当ctm中的事务提交或回滚时，与事务相关的对象所做的全部更改都一起被提交或取消。
When a transaction in a CTM commits or rolls back, all the changes made by the objects involved in the transaction are either committed or undone as a group.
下图是OTS规范，它展示了包含分布式对象的事务的各部分。
This diagram form the OTS specification shows the parts of a transaction involving distributed objects.
