RAC一个节点的数据库无法启动:ORA

一个客户的RAC节点硬件发生了变动，主机重启后数据库实例无法启动，远程登陆查看ALERT日志发现大量报错： Writingtotheabovetracefileisdisabledfornowon... Errorsinfile/oracle/app/diag/rdbms/XXXX/ XXXX 2/trace/ XXXX 2_ora_184464.trc: ORA-00600:inte

查了MOS，原因是主机的系统时间不对，文档是ORA-00600: internal error code, arguments: [4:kgstmLdiToEpochTs] (文档 ID 1334956.1)

抓紧检查节点主机时间，果然是时间不对--年份不对，月日时分秒都是一致。主机的时间应该是更换硬件后恢复了初始时间1970年。

联系客户联系人，协调SA调整时间，又折腾一通，终于全部搞定。。
