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
[root@db1 ~]# date
Fri Mar 24 11:26:44 CST 2017
[grid@db1 ~]$ srvctl start database -d caiwu
[grid@db1 ~]$ srvctl start database -d rlzy
[grid@db1 ~]$ crsctl stat res -t

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。
