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
