oracle 宕机后文件损坏resetlogs后处理

Posted 2020-11-10

数据库意外宕机，归档开了，但是归档文件损坏，redo损坏，在强行拉起来之后UNDO报错，设置_corrupted_rollback_segments 跳过不一致的ＵＮＤＯ，重建UNOD表空间，接着报错：SMON encountered 100 out of maximum 100 non-fatal internal errors. 然后数据库自动宕机，报错处理如下：
１ORA-00600: internal error code, arguments: [13013], [5001], [458], [4197442], [6], [4197442], [3], [], [], [], [], []

Arg [a] Passcount 错误代码5001
Arg [b] Data Object number 即object_id=458
Arg [c] Tablespace Relative DBA of block containing the row to be updated
Arg [d] Row Slot number
Arg [e] Relative DBA of block being updated (should be same as [c])
Arg [f] Code　３ update~~

select object_name,owner,object_type from dba_objects where object_id=458
analyze table mon_mods$ validate structure cascade;
ALTER INDEX I_MON_MODS$_OBJ REBUILD;
create table mod_mods_bak as select * from mon_mods$;
truncate table mon_mods$;
INSERT INTO MON_MODS$ SELECT * fROM MON_MODS_BAK;
select count(*) from mon_mods$;

2 OBJD=267 smon_scn_time报错

select object_name,owner,object_type from dba_objects where object_id=267;

果断报错

ORA-00600: internal error code, arguments: [kewrose_1], [600]由这个错误产生，mmon进程有关，非关键进程，可以杀掉重启，
