Exadata火线救援：10TB级数据恢复—强制拉库篇

发表于 2016 年 7 月 23 日 由 惜分飞

这个库的恢复有一些历史故事(【力荐】Exadata火线救援：10TB级数据修复经典案例详解！)：xx运营商x2的1/4配置的oracle exadata机器，跑了近6年，最近有一个cell节点主机异常,在rebalance过程中,只有两个节点的cell其中一个节点坏了一个硬盘导致.导致asm diskgroup无法正常mount,最后该运营商运维三方通过amdu把该一体机中的数据文件全部抽出来,然后在恢复过程中出现大量错误无法解决,请求我们支持
数据库open过程报ORA-01555错误

这个错误比较常见，可以通过推scn就可以解决,由于已经安装了scn patch,通过oradebug推scn解决该问题.

ORA-600 4194
这个ora 600 4194相对比较特殊,在SMON: enabling cache recovery之后立马报出来,然后实例直接open失败.

ORA-600 signalled during: alter database open...

数据库正常open失败,但是可以upgrade启动.根据对trace文件的分析,定位到问题在HISTGRM$表上面,进一步分析该表结构为

CREATE TABLE SYS.HISTGRM$
(
  OBJ#      NUMBER,
  COL#      NUMBER,
  ROW#      NUMBER,
  BUCKET    NUMBER,
  ENDPOINT  NUMBER,
  INTCOL#   NUMBER,
  EPVALUE   VARCHAR2(1000 BYTE),
  SPARE1    NUMBER,
  SPARE2    NUMBER
)
CLUSTER SYS.C_OBJ#_INTCOL#(OBJ#, INTCOL#);

这个和ORA-600 6711错误相匹配了

ERROR:
ORA-600 [6711] [a] [b] 1 [d]
VERSIONS:
versions 6.0 to 12.1
DESCRIPTION:
This error is generated when we find more blocks on a cluster key
chain than are supposed to be there.
Usually this indicates that the chain contains a loop within itself. We
cannot have more than 65535 blocks in a chain.
ARGUMENTS:
Arg [a] beginning DBA
Arg [b] table slot number (in table index)
Arg {c} dba of key next in chain
Arg [d] row slot of key next in chain

需要处理该错误,也就是需要处理CLUSTER SYS.C_OBJ#_INTCOL#,这个可以通过重建来实现,但是当重建之时发生

ORA-00600: internal error code, arguments: [kkoipt:invalid aptyp], [0], [0], [], [], [], [], [], [], [], [], []
ORA-08102: index key not found, obj# 39, file 1, block 1374829 (2)

这里错误比较明显obj#=39为obj$的i_obj4的index的记录和表不匹配,导致任何ddl无法执行,因此如果要处理C_OBJ#_INTCOL#就必须要先处理i_obj4的问题.通过一些技巧重建i_obj4,然后重建C_OBJ#_INTCOL#,数据库终于可以正常打开.由于大量数据字典不一致,exp/expdp导出依旧有问题,通过dblink直接拉数据到新库,完成本次恢复
补充说明：1. 在这个库的恢复过程中,我们还使用了大量的event和隐含参数,因为比较常规而且不涉及核心环节,因为未列举出来;2. 由于当时操作记录未能够保留日志因此相关操作步骤无法贴出来,本文只能提供恢复处理思路
再次提醒各位数据库做好备份,做好巡检工作,哪怕是强大的Oracle exadata也禁不起无备份折腾,数据重于一切

根据QREF kddummy_blkchk / kdBlkCheckError Check Codes Listing (Full) (Doc ID 1264040.1)分析
这里的18025是代码的KCBTEMAP_EC_START + KTS4_EC_SBFREE部分异常，主要表现在Incorrect firstfree or nfree 可以通过设置一些参数进行屏蔽

在恢复过程中还有其他错误

ORA 600 2662的错误处理
根据经验,这个错误只需要推scn即可,可以通过bbed,隐含参数,event,oradebug,修改控制文件等方法进行,推scn之后,数据库报熟悉的ORA-00604 ORA-00607 ORA-600 4194错误,以前我们遇到的block大部分是128,这次报异常block为9.实际中跟版本有关系,在ORACLE 9.2.0.6中该错误为file 1 block 9.大部分版本为128
