That impact is due to the overhead in creating and destroying those objects by the database resource manager process.
“数据库资源管理器”时,此窗口显示在开发环境的左边。
Database Explorer, the window appears on the left edge of the development environment.
数据库资源管理器拥有新的选项,允许对资源进行更好的控制。
The Database resource Manager has new options that allow for more granular control of resources.
在那种情况下,因为池管理器预先在启动时创建连接对象,所以,J2EE组件可以使用连接对象,而不会导致数据库资源管理器上的系统开销。
In that situation, a J2EE component can use connection objects without causing overheads on the database resource manager, since a pool manager creates the connection objects up front, at startup.
如果数据库是参与事务的唯一资源管理器,则数据是一致的。
If the database is the only resource manager that is participating in the transactions, the data is consistent.
接下来的各个部分将列出在中间件环境中这四个步骤的一些关键点,在这些环境中使用不同的数据库或消息传递产品作为资源管理器。
The next sections list some key highlights for these four steps in middleware environments using different database or messaging products as a resource manager.
对于JTAEntityManager, JTA事务被传递到底层的资源管理器(即虚拟数据库,由它将这个事务中继到物理数据库)。
For a JTA EntityManager, the JTA transaction is propagated to the underlying resource manager (i.e., the virtual database, which relays the transaction to physical databases).
〇默认情况下,这些列不在数据库文件夹的对象资源管理器详细信息页上可见。
By default, these columns are not visible on the Object Explorer Details page for the Databases folder.
只要涉及到资源管理器和库服务器数据库,一旦有了一次原始备份,并且所有日志均完好无损,即可保证不损失任何数据。
As far as Resource Manager and Library Server databases are concerned, once you have a baseline backup and all logs are intact, there is a guarantee that there will be no loss of data.
当一个EJB组件想访问数据库、消息队列服务器或者其它一些事务性资源时,它需要到资源管理器的连接(通常是使用JNDI)。
When an EJB component wants to access a database, a message queue server, or some other transactional resource, it acquires a connection to the resource manager (usually by using JNDI).
可以在数据库项目资源管理器窗口中看到新项目,如图5所示。
The new project can be seen in the database project explorer window, shown in Figure 5.
从数据源资源管理器,下钻到GSDB数据库中的GOSALESCT模式中的表。
From the data Source explorer, drill down to the tables in the GOSALESCT schema in the GSDB database.
从数据源资源管理器,下钻到GSDB数据库的GOSALES模式中的表。
From the data Source explorer, drill down to the tables in the GOSALES schema in the GSDB database.
在对象资源管理器,单击数据库文件夹。
资源管理器存储应用程序状态,常常是数据库,但也可能是消息队列服务器(在J2EE 应用程序中,它们将是 JMS提供者)或其他事务性资源。
The RMs store the application state and are most often databases, but could also be message queue servers (in a J2EE application, these would be JMS providers) or other transactional resources.
分布式事务支持,这样队列操作可以同其它资源管理器(如SQL数据库)一起参加分布式事务。
Distributed transactional support, so queue operations can participate in distributed transactions with other resource managers, such as SQL databases.
运行数据包括WebSphere事务日志、与流程服务器数据库关联的一些文件以及与任何其他资源管理器关联的一些文件。
The run data consists of the WebSphere transaction logs; some of the files are associated with the process server databases and some of the files are associated with any other resource managers.
WebSphere通常为协调器,而各种数据库、队列管理器、遗留系统,以及其他实体均为资源管理器。
WebSphere is typically the coordinator, and the various databases, queue managers, legacy systems, and other entities are the resource managers.
修改列在数据库文件夹的对象资源管理器详细信息页上的列表。
You modified the list of the columns on the Object Explorer Details page for the Databases folder. Additionally, you included at least one of the following columns.
从数据源资源管理器,下钻到GSDBNEW数据库的GOSALESCT模式中的cust表。
From the data Source explorer, drill down to the CUST table in the GOSALESCT schema in the GSDBNEW database.
从数据源资源管理器中下钻到GSDB数据库的GOSALES模式中的任何表,比如product表。
From the Data Source Explorer, drill down to any table in the GOSALES schema in GSDB, such as the PRODUCT table.
这个可视化的建模器和VisualStudio 2008整合在一起,开发人员可以借此通过从服务器资源管理器(ServerExplor)拖拉数据库表来创建模型。
The visual modeler is integrated with Visual Studio 2008 allowing developers to create the model by dragging database tables from the Server Explorer.
从数据源资源管理器中,导航到GSDBTEST数据库,并下钻到GOSALES模式。
From the data Source explorer, navigate to the GSDBTEST database, and drill down to the GOSALES schema.
然后,用户就可以通过Windows资源管理器来访问FileTable文件夹,并通过拖拽文件的方式来把它们添加到数据库中。
Users can then access the FileTable folder via Windows Explorer, and drag and drop files to add them to the database.
在基本的分布式环境中,对于资源(文件、打印机、数据库,等等)的访问是通过资源管理器(应用程序服务器)进行管理的。
In a fundamental distributed environment, access to a resource (whether a file, printer, database, etc.) is managed by resource managers (application servers).
点击“确定”按钮以创建这个数据库。“服务器资源管理器”窗口将反映出这个新的添加。
Click the OK button to create the database. The Server Explorer window will be updated to reflect the new addition.
“解决方案资源管理器”中,单击要配置其设置的数据库项目。
