在三层架构中，队列管理器只了解应用程序的身份。
In the three-tier architecture, the queue manager knew only the identity of the application.
并行作业管理器层同样也是计算网格的组成部分，可以将较大的作业分解为较小的分区、并为跨集群执行的分区作业提供操作控制。
Parallel Job Manager tier, also part of Compute Grid, decomposes large jobs into smaller partitions and provides operational control over partitioned jobs executing across the cluster.
当域对象离开数据访问层时，它与实体管理器脱离。
When a domain object leaves the data access tier, it gets detached from the entity manager.
组合使用并行作业管理器(PJM)、n层缓存结构和关联路由，可以提供功能强大的高性能计算网格。
Combining the Parallel Job Manager (PJM), N-tier caching structures, and affinity routing provides a powerful, high-performance compute grid.
从图1可以看出，使用JDBC 1.0通过数据库管理器获取和释放数据库连接将影响ejb层的性能。
You can see from Figure 1 that acquiring and releasing database connections via the database manager, using JDBC 1.0, will impact the performance on the EJB layer.
如果是一个数据库管理器层的配置参数。
diagpath参数是数据库管理器层的配置参数，它指向DB 2诊断信息的完整路径。
The diagpath parameter is the database manager level configuration parameter that points to the fully qualified path for DB2 diagnostic information.
这些GUI通常被称为窗口管理器，因为它们占用了 X-Windows细节层上面的一层，并且它们对窗口进行管理。
The GUIs are commonly known as window managers, because they occupy a layer above the nitty-gritty X-Windows layer and they manage windows for you.
有很多轻量级的窗口管理器可以使你更好的通过X层访问你的系统。
There are many lightweight window managers that will give you better access to your system through the X layer.
