在第二个阶段，每个登录模块提交它的登录的结果，用在登录阶段获取的凭证更新当前访问控制上下文的JAAS Subject。
In the second phase, each login module commits the outcome of its login, updating the JAAS Subject of the current access control context with credentials acquired during the login phase.
例如，对于队列，使用一个MQQUEUE概要文件来控制对该队列的访问，但是mqadmin类中的其他概要文件用于控制上下文和用户安全性。
For example, for a queue, an MQQUEUE profile is used to control MQI access to the queue, but other profiles in the MQADMIN class are used to control context and alternate user security.
通过实际应用来看，应用上下文技术可以用于提高细粒度访问控制的性能，从而提高数据库的安全性。
Application context can be useful for the purposes of enforcing fine-grained access control and enhances the security of database.
