我如何能知道哪个运行时主机正在运行我的代码吗？
通过尝试本文所给出的示例，您就能够体验到如何使用REOPT选项来提高那些包含主机变量或参数标记的查询的运行时性能。
Try out the examples in this article to experience how you can improve runtime performance for queries that contain host variables or parameter markers by using the REOPT option.
某些情况下，如果语句包含主机变量、参数标记或特殊寄存器那么访问路径在运行时的性能不会很好。
In some cases, the access path does not perform well at runtime if the statement contains host variables, parameter markers, or special registers.
更常见的情况是，您需要将运行时从一台机器迁移到另一台机器，修改主机名只是迁移过程中的一个步骤。
More likely, you need to move the runtime from one machine to another, which requires a change to the host name as part of that process.
J2ME技术在一个完整的应用程序运行时模型中定义了这种模块性和可伸缩性，在该模型中的四个软件层都构建在设备的主机操作系统上。
This modularity and scalability is defined by J2ME technology in a complete application runtime model, with four layers of software built upon the host operating system of the device.
在这种情况下，运行时分析结果都在目标内存中得到评价，直到您决定将其返回至主机为止。
In this case, runtime analysis results are evaluated in the target memory endlessly, until you decide to dump them back to the host machine.
单元的主机需求需要得到更新，以反映A SP.NET运行时需求。
The unit's hosting requirement needs to be updated to reflect the ASP.NET runtime requirement.
使用该脚本，我们可以获取命令行上提供的每个主机的正常运行时间列表(请参见清单6)。
Using the script, we can get a list of the uptimes for each host supplied on the command line (see Listing 6).
更新必要的源文件，以反映运行时环境的主机名。
Update the necessary source files to reflect the hostnames of your runtime environment.
客户机应用程序和ejb代理的源代码必须进行自定义，以反映运行时环境的主机名。

清单5显示了一个非常简单的脚本，此脚本将获得命令行上提供的每个主机的系统正常运行时间。
Listing 5 shows a very simple script that will obtain the system uptime for each of the hosts supplied on the command line.
在无权使用运行时环境或不了解特定主机上是如何存储及管理策略时，本地配置是不可见的。
Local configurations are not visible to people without access to the run-time environment or who do not have detailed knowledge of how the policy is stored and managed on a particular host.
由于该接口在所有设备中保持一致，您可以跨多个主机使用相同方法来获取正常运行时间、网络统计数据、磁盘空间甚至进程监视信息。
Because the interface is consistent across all the devices, you can get uptime, network statistics, disk space, and even process monitoring using the same methods across multiple hosts.
在此输出中，所显示的节点URL表明了运行节点的实际主机名称，而tuscany运行时则安装在c： \ tuscany \tuscany - sca - 1.3.1目录中。
In this output, the displayed URL of the node shows the actual host name where the node is run, while the Tuscany run time is installed in the c: \ Tuscany \ tuscany-sca-1.3.1 directory.
多机集中控制：用一台集中控制器可以对多台主机进行集中控制，根据系统负荷及个单元运行时间决定主机工作状态。
Multi-centralized control: The controller can be a focus of many central control console, according to system load and run-time units decide the host job status.
如果主机要求挂钩，则运行时不内联调用。
If the host requires a hook, the runtime does not inline the call.
