从消极的方面看，容器对装入条件和数据请求模式的响应是不可预知的，所以必须在开发过程中添加大量的基于方案的装入测试。
On the negative side, the container's response to load conditions and data request patterns is unpredictable, so extensive scenario-based load testing must be added to the development process.
如果多个箭头显示一个环形的锁请求模式—由于它们正在相互等候其它线程释放锁，所以线程彼此阻止运行—结果就形成了一个死锁。
If multiple arrows show a circular lock-request pattern — threads prevent each other from running because they are waiting for each other to release a lock — then you have a deadlock.
在这个示例中，您可以考虑请求端缓存模式。
You can consider the Requester side Caching Pattern in this case.
在这个模式中，请求和响应是单独的WSDL操作内定义的两条消息。

如果没有匹配的odr路由规则，则默认行为是考虑单元中所有拥有匹配请求的URI模式的应用程序。
If there are no ODR routing rules, then the default behavior is to consider all the applications in the cell that have URI patterns which match the request.
请求端缓存模式经常能够提供性能问题的有效解决方案，但架构师需要谨慎考虑一系列因素。
The requester-side caching pattern can often provide an effective solution to a performance problem, but the architect needs to carefully consider a number of factors.
XACML标准(见参考资料获得详细信息)要求根据XACML请求和响应模式定义所有授权请求。
The XACML standard (see Resourcesfor more information) requires all the authorization requests to be defined according to the XACML request and response schema.
您可以使用请求端缓存模式来实现写策略。
You can use the Requester Side Caching Pattern to implement the On Write policy.
在这个实例中，请求是REST模式的。
客户机使用上述的请求应答协议获得模式信息。
Clients use the same request response protocol described above to get the schema information.
图17显示了应用请求端缓存模式后的序列关系图。
Figure 17 shows the sequence diagram after having applied the requester-side caching pattern.
在出现不完全符合由面向对象的方法模式所公开的典型同步请求-响应模式的情况时，如何处理？
How can cases be handled that do not fit neatly into to the synchronous request-response pattern typically exposed by the object-oriented method pattern?
本文将详细讨论请求端缓存模式；此模式用于处理请求端的缓存。
This article details the requester-side caching pattern, which addresses caching on the requester side.
现在可以基于模式规范创建多个请求端缓存模式实现。
Numerous requester-side caching pattern implementations can now be created based on the pattern specification.

Listing 4 shows the request format, the REST URL pattern, and the server response to the request.
服务消费者根据STAR模式创建目录请求文档。
The service consumer creates an inventory request document according to the STAR schema.

通常，当使用名称请求组时会加载组；在递归模式下，所请求组的所有子组也会加载。
Ordinarily, groups are loaded as you request them by name; in recursive mode, all subgroups of requested groups are also loaded.
