数据库启动的时候直接关闭，查看告警日志：

在初始化参数中加入：

event='10061 trace name context forever, level 10'
_smon_internal_errlimit=1000000

再次启动数据库：

SYS@orcl11g>alter database open;alter database open*ERROR at line 1:ORA-00600: internal error code, arguments: [4194], [0x000000011], [0x000000000], [], [], [], [], [], [], [], [], []SYS@orcl11g>SYS@orcl11g>SYS@orcl11g>SYS@orcl11g>select open_mode from v$database;OPEN_MODE----------------------------------------READ WRITE

这时候我们重建undo表空间，问题解决
