问题背景：
客户数据库服务架构为一主一备，某日备库操作系统意外重启，重启后Oracle MRP进程起不来，
报错：ORA-00600: internal error code, arguments: [2619], [227424], [], [], [], [], [], [], [], [], [], []
1> 检查MRP进程
SQL> select process,status from v$managed_standby;
PROCESS STATUS
------- ------------
ARCH CONNECTED
ARCH CONNECTED
MRP0 WAIT_FOR_LOG
RFS RECEIVING
没有MRP进程，说明备库没有处于恢复状态。尝试启动MRP进程
alter database recover managed standby database disconnect from session ；
MRP进程起不来，报错日志如下：

发现这个600错误是备库在执行恢复的过程中，发现227424这个归档日志有问题或者找不到,导致日志应用失败，
错误原因是因为Errors with log /oraarchivelog/oradb/oradb_1_227424_866810169.arc
这条日志有问题,把归档日志下的这条日志删除，然后从主库传输过来这条日志，
2> 手动重新应用这条日志
alter database register OR replace logfile '/home/oracle/oradb_1_227424_866810169.arc';
3> 开启日志应用
alter database recover managed standby database disconnect from session；
或者数据库open状态下
alter database recover managed standby database using current logfile disconnect from session;
修复完成，问题解决
