查看rlzy实例的alert.log文件，可以看到以下错误信息“ORA-00600: internal error code, arguments: [2252], [3418], [573259345], [1594], [50675712]”，关于这个ORA-00600 2252在MOS上有相关bug描述，但我这并不是bug引起的，查看信息时我们也是需要关注时间的，这里时间显示为2001年1月1号了，与当前时间相差了16年2个多月。

查看系统当前时间,居然变成了2001年1月1号，而且奇怪的是并不是重启时时间就被修改了，因为有两个实例在重启之后正常启动了

[root@db1 ~]# date
Mon Jan  1 08:25:34 CST 2001

手工更新为当前时间后并手动启动实例(caiwu,rlzy)，就能正常启动

问题虽然解决了，但是为什么服务器会在启动两个实例后，系统时间发生改变还是不得而知，需要找浪潮服务器的工程师来检查。
