ORA-01578的处理

某天一台数据库测试机出现 ORA-01578，虽说这是测试机但是这是客户用的，随便处理也不行，仔细研究一下。

ORA-01578: ORACLE data block corrupted (file # 2, block # 69449)

ORA-01110: data file 2: '/oracle/app/oradata/BOSS/sysaux01.dbf'

看看是在什么对象上

SELECT SEGMENT_TYPE,OWNER||'.'||SEGMENT_NAME FROM DBA_EXTENTS WHERE file_id = 2 AND 69450 BETWEEN BLOCK_ID AND BLOCK_ID+BLOCKS -1;

用dbv看看能不能看到什么情况

dbv file =/oracle/app/oradata/BOSS/sysaux01.dbf

[14:26:30 oracle@SXWG]/home/oracle>dbv file =/oracle/app/oradata/BOSS/sysaux01.dbf

尼玛看不到什么问题

看看可以直接rebulit不

14:33:18 sys@BOSS> alter index SYSMAN.MGMT_METRICS_RAW_PK REBUILD tablespace system online nologging; 

alter index SYSMAN.MGMT_METRICS_RAW_PK REBUILD tablespace system online nologging

*

ERROR at line 1:

ORA-28650: Primary index on an IOT cannot be rebuilt

用下面这句也看不到什么情况

dbv file=/oracle/app/oradata/BOSS/sysaux01.dbf blocksize=8192

用这个检查，也不知道什么

RMAN> BACKUP CHECK LOGICAL VALIDATE DATAFILE 2;

想移表再重建索引，好像也不行

 alter table SYSMAN.MGMT_METRICS_RAW move tablespace system;

 

 alter table SYSMAN.MGMT_METRICS_RAW move tablespace system

                   *

ORA-01578: ORACLE data block corrupted (file # 2, block # 69449)

ORA-01110: data file 2: '/oracle/app/oradata/BOSS/sysaux01.dbf'

 

 看看在哪个列上

 select table_name,COLUMN_NAME from dba_ind_columns where index_name='MGMT_METRICS_RAW_PK';

 

 

 打算把它drop掉再建，先看看创建语句先。

 select dbms_metadata.get_ddl('INDEX','MGMT_METRICS_RAW_PK','SYSMAN') from dual;

 

 

   CREATE UNIQUE INDEX "SYSMAN"."MGMT_METRICS_RAW_PK" ON "SYSMAN"."MGMT_METRICS_RAW" ("TARGET_GUID", "METRIC_GUID", "KEY_VALUE", "COLLECTION_TIMESTAMP")

  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)

  TABLESPACE "SYSAUX"

  

  

  drop index SYSMAN.MGMT_METRICS_RAW_PK ;

  

尼玛发现drop不了，主键约束

  

看看能不能把约束先drop了

  select CONSTRAINT_NAME,CONSTRAINT_type from dba_constraints where table_name='MGMT_METRICS_RAW';

  

尼玛又不能drop

  alter table sysman.MGMT_METRICS_RAW drop constraint MGMT_METRICS_RAW_PK;

  

16:25:14 sys@BOSS> alter table sysman.MGMT_METRICS_RAW drop constraint MGMT_METRICS_RAW_PK;

alter table sysman.MGMT_METRICS_RAW drop constraint MGMT_METRICS_RAW_PK

*

ERROR at line 1:

ORA-25188: cannot drop/disable/defer the primary key constraint for index-organized tables or sorted hash cluster

  

想试试能不能把数据导出，再把用户清了重导

  nohup exp sysman/oracle buffer=48000000 file=/data/backup/sysman.dmp log=/data/backup/sysman.log &

  

  nohup exp sysman/oracle buffer=48000000 file=/data/backup/sysman2.dmp log=/data/backup/sysman2.log tables=MGMT_METRICS_RAW &

  

  

事实证明这个也不行。。。

打算拷一个表的数据

  create table SYSMAN.MGMT_METRICS_RAW_COPY as select * from SYSMAN.MGMT_METRICS_RAW;

  

  

  create table SYSMAN.MGMT_METRICS_RAW_COPY tablespace system as select * from SYSMAN.MGMT_METRICS_RAW;

  

  16:48:04 sys@BOSS> create table SYSMAN.MGMT_METRICS_RAW_COPY tablespace system as select * from SYSMAN.MGMT_METRICS_RAW;

create table SYSMAN.MGMT_METRICS_RAW_COPY tablespace system as select * from SYSMAN.MGMT_METRICS_RAW

                                                                                    *

ERROR at line 1:

ORA-01578: ORACLE data block corrupted (file # 2, block # 69449)

ORA-01110: data file 2: '/oracle/app/oradata/BOSS/sysaux01.dbf'

尼玛这都不行。。。

最后放个大招解决了

emca -deconfig dbcontrol db -repos drop

 emca -config dbcontrol db -repos create
