如何添加一个沙箱应用程序调度？
针对时间而不是分配率进行调度的原因是：在应用程序执行期间，分配率通常都是不均匀的。
The reason for scheduling against time instead of allocation rate is that allocation is often uneven during an application's execution.
具有实时特征的调度允许这些关键功能与一些尽力运行的应用程序共存。
Scheduling with real-time characteristics allows the critical functions to coexist with applications that operate on a best-effort basis.
前面的SHEEP应用程序例子说明了使用时间触发预定行为的弱点——这个程序可以跳过调度触发。
The earlier SHEEP application example illustrated a weakness in using time to trigger scheduled actions — the program can skip over schedule triggers.
执行自身形式的线程入池和线程调度的应用程序或库可能需要这种技术。
This technique might be required for applications or libraries that do their own form of thread pooling and thread dispatching.
在进行了合适的响应时间分解配置之后，您必须执行测试或者调度以在负载测试期间初始化应用程序监控。
After making the appropriate response time breakdown configuration, you must execute the test or schedule to initiate application monitoring during the load test.
接口映射导入和导出的服务用于在应用程序及中央调度逻辑之间发送和接收业务对象。
The services imported and exported by the interface maps send and receive business objects to and from the applications and the central dispatching logic.
要实现这一点，您必须进行折中，将并行部署减至最低程度；例如，您的应用程序团队可能会对一个部署调度达成一致意见。
To alleviate this, you must strike a compromise so that parallel deployment is minimized; for example, your application teams could agree upon a deployment schedule.
很多应用程序都假定由操作系统提供内存管理功能或进程调度功能。
Many applications assume the memory management features, or process scheduling features, provided by the OS.
尽管如此，FIFO调度机制为尝试减少延迟的应用程序设计师提供了一项重要帮助。
Nonetheless, FIFO scheduling provides an important helping hand to an application designer trying to put a cap on delays.
由于可能同时调度多个并发的XMLHTTP请求，应用程序本质上变成了一个并发程序，而并发很难实现。
Because multiple concurrent XML HTTP requests can be scheduled in parallel, our application essentially becomes a concurrent program — and concurrency is hard.
更不用说，云计算提供商必须能够在没有人工干预的情况下处理生产意外、管理应用程序和工作负载服务水平和资源以及调度活动。
Not to mention that cloud providers need the ability to handle production exceptions, manage application and workload service levels and resources, and schedule activities without human intervention.
对限额的调度对应用程序性能的影响极小，其延迟可低至几百微秒，通常小于1毫秒。
The scheduling of quanta has an extremely low impact on application performance, with delays as low as hundreds of microseconds but typically less than 1 millisecond.
以下是一些在应用程序中应该询问的关于调度行为的问题。
Following are some questions you should ask regarding scheduled actions in your application.
LotusWorkflow是一种应用程序，可以帮助组织计划、调度、跟踪、监控和存档基于文档的工作和项目。
Lotus Workflow is an application that allows your organization to plan, schedule, track, monitor, and archive its document-based work and projects.
一个必须在精确时间内响应事件的应用程序无法确保不会在一个高优先级线程之前调度另一个低优先级线程。
An application that must respond to events in a well-defined time has no way to ensure that another low-priority thread won't get scheduled in front of a high-priority thread.
本文介绍了如何用WorkManager接口对工作进行调度，以便在应用程序的控制下处理这些工作。
This article examined how you can use the WorkManager interface to schedule work for processing on a thread under the application server's control, either synchronously or asynchronously.
使用这个方法可以监控那些没有进行自动化监控的J2EE、非j2ee和Webservice应用程序，这可以适用于性能测试或者调度的情况。
Use this method for monitoring J2EE, non-J2EE, and Web service applications that do not have automated application monitoring, which is the situation with a performance test or schedule.
DB 2Viper现已可用(用于评估)，本教程可用于帮助您了解如何组合使用XML和SQL，从而构建灵活调度应用程序的基础。
DB2 Viper is now available (for evaluation purposes) and this tutorial can be used to aid in understanding how to use XML and SQL together to build the basis of a flexible scheduling application.
他们推荐了用于控制应用程序线程位置的taskset，以及用于更改调度的chrt命令。
They suggest that taskset be used to control placement of the threads of the application, and that the CHRT command be used to change the scheduling.
然后，每个应用程序服务器都将使用自己的调度程序线程在其内执行自己的分派。
Each application server would then perform its own dispatching within itself, using its own dispatcher thread.
由于应用程序a使用并阻塞了托管任务，因此其他应用程序无法调度。
As the managed tasks are consumed and blocked by application a, other applications are unable to dispatch.
这样的示例有调度驱动程序所使用的传递记录应用程序，来自现场销售代表的订单输入系统等。
Examples of this are the delivery recording applications used by dispatch drivers, order entry systems from field sales representatives, and so on.
但是，要利用FIFO调度机制的易变性优势，可能需要进一步更改您的应用程序。
Taking advantage of the variability benefits of FIFO scheduling, however, can require some further changes to your application.
您可以配置应用程序/批处理服务器域以及进程调度器。
You can configure the application/batch server domains and process scheduler.
实现这种心跳或调度器应用程序有多种方法。
There are multiple ways to implement such a heartbeat or scheduler application.
一种影响数据库大小的常用设计模式是引入“心跳”或“调度器”应用程序。
A design pattern that is often applied, and has impact on the database size, is to introduce a "heartbeat" or "scheduler" application.
调度逻辑直接将业务对象发布到所有与更改相关的应用程序(在本例中只有一个应用程序)。
The dispatching logic simply publishes business objects to all applications interested in the change (in this case, only one application).
应用程序在设计上可拥有多个用户级线程，并将它们计划为由应用程序或libpthread中的pthread调度程序处理。
Applications can be designed to have user-level threads that are scheduled to work by the application or by the pthreads scheduler in libpthreads.
POSIX允许您创建具有不同线程调度策略和优先级的POSIX线程(pthreads)以满足不同应用程序的需求。
POSIX allows you to create POSIX threads (pthreads) with different thread scheduling policies and priorities to meet differing application needs. Three such scheduling policies are.
