Next you need to add the necessary activities in the fault handler such as the following
接下来需要在故障处理程序中添加必要的活动，如下所示
The fault handler USES compensation handlers to undo actions that have already been committed.
错误处理器使用补偿处理器来“撤销”之前已经提交的动作。
In the details for the Catch element in the fault handler, select User-defined for the fault type.
在错误处理程序的Catch元素的详细信息中，选择user - defined作为错误类型。
In the outer scope, a fault handler contains a compensate activity whose target is set to the inner scope.
在外部范围中，错误处理程序包含一个其目标设置为内部范围的补偿活动。
In the process editor, the process and each activity within it can have a fault handler associated with it.
在Process编辑器中，流程及其内部的每个活动都可以有一个与其有关的故障处理程序。
A fault handler of a scope may make use of compensation handlers to undo actions performed within that scope.
作用域的故障处理程序可能使用补偿处理程序来撤销这个作用域中进行的操作。
Once you've created the fault handler, you'll need to register it in the deployment descriptor, as noted above.
一旦您创建了故障处理程序，您将需要在部署描述符中注册它，这一点上面已经提到过。
This is required if an unexpected error occurs and there is no fault handler specifically modeled to handle it.
如果发生意外错误，并且没有专门建模错误处理程序来处理该错误，则需要该操作。
The activity is then put in state failed and the fault is propagated to the fault handler of the next enclosing scope.
然后将该活动置于已失败状态，并且将错误传播到下一个封闭范围的错误处理程序。
First, in this example, you need to add a fault handler on the selected BPEL activity to catch the exceptions it throws.
首先，在本实例中，用户需要在选择的BPEL活动中添加故障处理程序，来捕捉其抛出的异常。
Under the ShippingFault element in the fault handler, add a snippet activity, and then fill in the details as in Figure 27.
在错误处理程序的ShippingFault元素下，添加snippet活动，然后如图27所示填写详细信息。
If something goes wrong after the inner scope has completed and the fault handler runs, then the CorrectNotify activity runs.
如果在内部范围完成之后发生了错误，并且错误处理程序在运行，则会运行CorrectNotify活动。
The fault handler in Listing 6 below defines the set of faults it attempts to handle via a corresponding set of elements (line 36).
在下面的清单6中，故障处理程序通过相应的一组元素(第36行)定义了它试图处理的故障集。
Again, the main scope needs a fault handler in order to prevent the fault from being propagated to the surrounding scope or process.
同样，为了防止错误传递到周围的范围或流程，主范围需要一个错误处理程序。
Note that clicking the orange and red 'x' at the top-right of the scope activity toggles between showing and hiding the fault handler.
请注意，单击范围活动右上角的橘红色“x”号可以在错误处理程序的显示和隐藏之间进行切换。
A fault handler is triggered when a fault is thrown by the runtime infrastructure, when a service is called, or when a throw activity runs.
当运行时基础结构抛出错误时、调用服务时或者在抛出活动运行时会引发错误处理程序。
When a fault occurs within a scope, the regular processing within the scope is interrupted and the signaled fault is passed to the catching fault handler.
当故障在作用域中发生时，作用域中的正常处理被中断，发出的故障被传给捕获故障的处理程序。
When a fault occurs within a process and regular execution is no longer possible, you use a fault handler to attempt to find another way to complete the process.
流程内出现故障，不可能再正常执行时，可以使用故障处理程序试图寻找其他方法完成流程。
In this example (see also Figure 5), we added a fault handler on the Validate and generate Topology activities to capture all of the faults generated in that activity.
在本实例中(参阅图5)，我们在Validate和GenerateTopology活动上添加了故障处理程序以捕捉这个活动中产生的所有错误。
When a problem or exceptional situation occurs while a process runs, you can use a fault handler to undo partial and unsuccessful work for the scope in which the fault occurred.
当流程在运行过程中出现问题或发生异常情况时，可以使用错误处理程序撤消发生错误的范围中的部分工作或未成功完成的工作。
Fault handling in this context can be as easy as doing nothing — simply the existence of the custom fault handler prevents the fault from being propagated to the enclosing scope or process.
此上下文中的错误处理非常简单——只要有自定义错误处理程序存在，就可以防止将错误传播到周围的范围和流程。
The activity nested within this fault handler tries to correct the situation such that regular processing can continue outside the scope or alternate ways to complete the process can be taken.
嵌套在这个故障处理程序中的活动试图纠正这种状况，以使正常处理可在作用域外继续或使用其它方法来完成流程。
If the fault Selector detects a fault, the current message will be processed by a fault Handler rather than by a Data Handler.
如果FaultSelector检测到一个错误，当前消息将由Fault Handler而不是Data Handler处理。
Within this Fault Handler, we update the system availability indicator to reflect the unavailability of the target Queue Manager.
在这个Fault Handler中，我们更新系统可用性指示器来反映目标QueueManager的不可用性。
Similar to the Data Handler, the Fault Handler lets you create a message parsing capability that can be used across a number of transports.
与DataHandler类似的是，Fault Handler使您可以创建可跨多个传输使用的消息解析功能。
