可以看到时间有一个大量的向回改的过程，日志显示为1976年，报错MOS解释如下：

CHANGES

In the scenario where this problem happened there was a power outage and somehow the operating system clock got misconfigured.

CAUSE

The operating system date and time changed.

SOLUTION

Correct the operating system date and time and re-start the instance.

所以向回改时间需要注意，尽量关闭数据库，同时等到当前时间超过原有时间后启动数据库
