受信任上下文是一个对象，它为用户提供一组特定的特权，当用户通过一个受信任的连接连接到数据库时，便可以使用它。
A trusted context is an object that gives users a specific set of privileges and is available when the user connects to the database through a trusted connection.

需要注意得是，任何消息都包含事务协调上下文，不管是应用程序间的消息还是应用程序发送给数据库的消息。

最后，验证联合数据库服务器可信上下文对象中的信任属性与连接请求中出现的信任属性相匹配。
Finally, verify that the trust attributes in the trusted context object on the federated database server actually match the trust attributes that are being presented in your connection request.
此外，无状态很难实现，可能会导致多次往返数据库来获取本来通常存储在会话上下文中的信息。
Additionally, statelessness can be difficult to achieve and can lead to multiple round trips to the database for information that is normally stored within the context of the session.
第一次连接到服务器时，将在数据库连接和可信上下文之间建立关系，这种关系将在连接期间一直维持。
The relationship between a database connection and a trusted context is established when the connection to the server is first made and that relationship remains for the life of that connection.
CLI可与多个源文件、上下文文件和DB 2数据库产品表空间一起使用。

更酷的是我们可以从asp页面(需要从数据库中读取配置)中即时生成应用上下文。
Even cooler was that we could generate application contexts on the fly from ASP pages that would read the Settings from a database.
在事务完成或上下文清仓时，会自动更新有关的数据库记录。
Appropriate database records are updated automatically when the transaction is committed or the context is flushed.
当建立一个数据库连接时，DB 2将那个连接的属性与数据库中每个可信上下文对象的定义相比较。
When a database connection is established, DB2 compares the attributes of that connection against the definitions of each trusted context object in the database.
通过使用可信上下文，可以在使用受限制的、敏感的特权时提供更强的控制，并且使中间层服务器或应用程序可以向数据库服务器确定用户的身份。
Using trusted contexts provides greater control while using restricted, sensitive privileges, and allows middle-tier servers or applications to assert the identity of the user to the database server.
在连接时，DB 2检查连接是否与数据库中可信上下文对象相匹配。
At connect time, the DB2 server checks to see if the connection matches the definition of a trusted context object in the database.
即使WLM没有显式地使用服务类(即数据库管理员没有定义任何服务类)，所有用户事务都是在预定义的服务类上下文中执行的。
Even if WLM is not explicitly used (that is, no service classes are defined by the database administrator), all user transactions are executed within the context of the predefined service class.
为验证您有合理的环境变量设置，您可以尝试像之前一样连接到数据库dirdb01；现在它应当可以通过root上下文工作了。
To verify that you have the proper environment variable setup, you can try to connect to the database DIRDB01 as shown earlier; it should work from root context now.
对于DataWebServices，受信任上下文使 Web服务客户机可以使用一个用户id进行身份验证，并且让数据库用相同的用户 id权限为这个请求服务。
With Data Web Services, trusted context allows for a Web service client to authenticate using a userid, and it allows the database to service this request using the authority of the same userid.
持久化上下文作用域划定到数据库事务。
当连接属性匹配DB 2服务器中定义的惟一可信上下文的属性时，可以将数据库连接当作可信连接。
A database connection is referred to as a trusted connection when the connection attributes match the attributes of a unique trusted context defined at the DB2 server. The "trust" is based on.
portlet本身使用portlet上下文获取连接Domino数据库所需的运行时参数（名称、视图、身份验证类型、凭证、Domino服务器和端口，等等）。
The portlets themselves use the portlet context to get the runtime parameters for connecting to the Domino database (name, view, authentication type, credentials, Domino server and port, and so on).
对交互集定义了上下文关系之后，每个已处理事件都需要将少量的上下文信息写到BusinessEvents储存数据库中。
When interaction sets have a context relationship defined, each processed event needs to write a small amount of context information to the Business Events repository database.
WebSphereInformation Integrator通过在其自身的编目中存储联邦数据源的元数据，从而在DB 2UDB数据库引擎的上下文中构建数据库联邦。
