aix环境10g由于控制器异常导致ORA-600 4000故障处理

一台运行在aix环境下面的10.2.0.1的数据库

由于控制器异常导致数据库启动的时候报ORA-600 4000错误

ORA-600 4000这个是在10g版本中非常常见的一个错误,一般是由于对应的block上面有事务没有提交或者scn过大导致,跟踪数据库启动过程发现在以下sql语句报错,而且报错为file 1 block 27527

EXEC #2:c=0,e=62,p=0,cr=0,cu=0,mis=0,r=0,dep=1,og=4,tim=437860213380
WAIT #2: nam='db file sequential read' ela= 139 file#=1 block#=27527 blocks=1 obj#=-1 tim=437860213555

ksedmp: internal or fatal error
ORA-00600: internal error code, arguments: [4000], [9], [], [], [], [], [], []
Current SQL statement for this session:
select rowcnt,blkcnt,empcnt,avgspc,chncnt,avgrln,nvl(degree,1), nvl(instances,1) from tab$ where obj# = :1

这里可以获取到两个有效信息:
1. 报错block为：file 1 block 27227
2. 报错sql为：select rowcnt,blkcnt,empcnt,avgspc,chncnt,avgrln,nvl(degree,1), nvl(instances,1) from tab$ where obj# = :1

进一步对报错数据块进行分析

Block header dump:  0x00406b87
 Object id on Block? Y
 seg/obj: 0x2  csc: 0xfe0.a99d3719  itc: 2  flg: -  typ: 1 - DATA
     fsl: 0  fnx: 0x0 ver: 0x01
 
 Itl           Xid                  Uba         Flag  Lck        Scn/Fsc
0x01   0x000b.014.00f1bb09  0x008027a5.eada.0e  C---    0  scn 0x0fda.f353b198
0x02   0x0009.01e.00212e2a  0x01400cdf.113e.01  --U-    1  fsc 0x0000.a99d371b

这里可以确认几个有效信息:
1. 该block的csc scn为:17457592743705
2. 一条已经提交的事务的scn为:17433059635608
3. 还有一条没有提交的事务,使用的回滚段为9,这个和我们报错的ORA-600[4000][9]这个回滚段名称匹配上

基于上述分析,我们需要确认两件事情:
1. 通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本检查结果,确认当前是数据库的文件头scn为:17457591420434小于该block的csc scn
chk

2. itl操上面有一个锁需要提交,通过bbed工具对其进行提交,然后得出dump block信息

Block header dump:  0x00406b87
 Object id on Block? Y
 seg/obj: 0x2  csc: 0xfe0.a99d3719  itc: 2  flg: -  typ: 1 - DATA
     fsl: 0  fnx: 0x0 ver: 0x01

 Itl           Xid                  Uba         Flag  Lck        Scn/Fsc
0x01   0x000b.014.00f1bb09  0x008027a5.eada.0e  C---    0  scn 0x0fda.f353b198
0x02   0x0009.01e.00212e2a  0x01400cdf.113e.01  C---    0  scn 0x0000.a99d371b

修改好itl之后,先尝试重启库,如果不出意外应该会报ORA-600 2662类似错误（因为前面分析了csc scn大于文件头scn的问题）
2662

这里的ORA-600 2662中的4221831就是报错的rdba地址(10进制),通过dbms_utility.data_block_address_file转换

SQL> select dbms_utility.data_block_address_file(4221831) "file",
  2  dbms_utility.data_block_address_block(4221831) "block"
  3   from dual;

      file      block
---------- ----------
         1      27527

得出报错的ORA-600 2662的block就是我们之前分析和修复的itl块,通过修改该块scn或者修改数据库scn,该库均可open,后续就是安排导出数据导入新库的活

初步分析该错误是由于oracle bug引起,在11.2.0.4版本中比较少见,主要常见于19c版本中
kcvent_intcic_zero_half

正常情况下,实例重启即可,这个客户比较不幸,数据库重启遭遇ORA-600 3716错误

不当恢复truncate数据导致数据库不能open处理

发表于 2026 年 1 月 30 日 由 惜分飞

有客户误truncate操作干掉了数据库中的几张表,然后尝试通过FY_Recover_Data进行恢复,恢复到一半然后终止了,数据库结果就起不来了(具体什么原因不知道,肯定是各种不合适的操作引起的故障),我接手故障的时候,数据库被强制resetlogs,报ORA-600 2662错误

该报错比较明显是由于undo回滚段异常导致,通过屏蔽回滚段,open库成功.后续对客户truncate的表进行分析,比较悲催由于没有第一时间保护现场而且对所在表空间进行了大量写入操作,导致truncate数据恢复较少.
