在此情形下，利用几何过程和补充变量法求得了该系统首次故障前的平均时间及另一些感兴趣的可靠性指标。
Under these assumptions, some reliability indices are derived by using the geometric process and the method of supplementary variable.
日志记录提供了故障前应用程序状态的详细信息，如变量的值、函数的返回值等等。
Logging provides the maximum amount of detail of the application state before the failure, such as value of variables, return value of functions, and so on.
的确出现故障时，在故障出现前未写出的数据可能会丢失，并不会因为服务器使用数据库还是DRS持久性解决方案而有所差别。
