MRP进程起不来：ORA-00600: internal error code, arguments, [227424], [], []

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： Clearing online redo logfile 5 complete Media Recovery Log /oraarchivelog/xxxx/oradb_1_227424_866810169.arc Errors in file /u01/oracle/diag/rdbms/oradb/oradb/trace/oradb_pr00_5429.trc  (incident=48266): ORA-00600: internal error code, arguments: [2619], [227424], [], [], [], [], [], [], [], [], [], [] Incident details in: /u01/oracle/diag/rdbms/oradb/oradb/incident/incdir_48266/oradb_pr00_5429_i48266.trc Completed: ALTER DATABASE RECOVER  managed standby database disconnect from session   Use ADRCI or Support Workbench to package the incident.

Sweep [inc][48266]: completed Sweep [inc][48257]: completed Sweep [inc2][48266]: completed Sweep [inc2][48257]: completed 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
