A database instance failure is typically caused by an operating system crash or a power outage.
数据库实例故障通常是由于操作系统崩溃或断电造成的。
As described in this section, if you know the cause of an instance failure, a complete recovery may not be necessary.
正如本部分所描述的，如果导致实例故障的原因是已知的，就不必进行完全恢复。
Keep in mind, in order to repair a process instance, it might be necessary to update one or more process variables to avoid the same failure again before one of these functions can be applied.
请注意，为了修复流程实例，可能需要更新一个或多个流程变量，以避免在应用其中某个功能之前再次发生相同的故障。
After the instance is in place, it is then possible to use the logs to pinpoint errors or use the post-processing scripts to identify performance or failure trends over multiple runs of the instance.
当实例位于恰当的位置并运行了多次之后，就可以使用日志查明错误或使用后处理程序脚本确定性能或故障趋势。
After the failed airliner bombing on Christmas, for instance, I seemed to hear and read a lot of complaints about his failure to address the nation-to comfort and reassure, to calm nerves.
比如说，在圣诞节炸飞机未遂事件之后，我听到也读到许许多多人都在抱怨他管理国家失当——他没有很好地让人民宽慰和放心下来，没有舒缓这个国家紧张的神经。
In this configuration, the active instance of both WebSphere MQ and WebSphere Message Broker run on the same physical server after failover, which makes this server a single point of failure.
在这种配置中，WebSphereMQ和WebSphereMessageBroker的主动实例在故障转移后运行在同一个物理服务器上，这使得该服务器成为单个故障点。
For instance, if the database is not mission-critical and 24x7, some downtime and loss of data may be acceptable, and re-keying of data may be an acceptable option should media failure occurs.
例如，如果数据库不是任务关键型和24x7型的，那么停机上一段时间和丢失一些数据可能是可以接受的，对于媒介错误，重新键入数据也可能是一种可以接受的方法。
For instance, transformers could suffer higher failure rates and efficiency of some types of thermal power station could be markedly reduced because of increasing temperatures.
例如，因为温度的不断增高，变压器可能出现较高的失效率，而某些类型的火力发电站的效能也可能会显著的降低。
For instance, if a laser is experiencing an overcurrent situation that could lead to machine failure, the sensors would detect this so that the situation can be addressed before a failure occurs.
举例说明，如果一个激光器正处于电流过载状态，持续下来可能导致机器损坏。传感器能够探测出异常，在损坏发生之前提醒操作人员进行处理。
If the instance is shut down (or suffers some sort of failure), information persisted on the file system is lost.
如果关闭实例(或发生了某种故障)，那么存储在此文件系统上的信息就会丢失。
Perhaps the instance is performing some form of work, but only to help prime a recovery in the event of a failure; for example, in a High Availability Disaster Recovery (HADR) scenario.
这个实例可能正在执行某种形式的工作，而只是在出现故障事件时帮助启动恢复（例如在 HADR 场景中）。
For instance, adding elements to a Queue could be done with the add method of Collection, throwing an unchecked exception on failure.
例如，向Queue添加元素可以用Collection的add方法来实现，它在失败时会抛出未检测异常。
Kidney failure produces a fishy smell and uncontrolled diabetes generates fruity fumes, for instance.
如，肾功能衰竭产生一种腥味，糖尿病产生水果味的气体。
For instance, the goal in climbing is to avoid muscular failure at all costs and, hopefully, reach the top of a boulder problem or climb before the arm and forearm muscles pump out.
举例说吧，攀爬的目的是想方设法避免肌肉力竭，在手臂和前臂肌肉力竭前有希望到达顶点。
For instance, when heart rate goes up these patients cannot produce enough ATP and then result in going into heart failure.
例如，当心率升高时，这些患者不能产生足够的AT P，于是导致进入心力衰竭状态。
For instance, when heart rate goes up these patients cannot produce enough ATP and then result in going into heart failure.
例如，当心率升高时，这些患者不能产生足够的AT P，于是导致进入心力衰竭状态。
