Data Block Corruption error
Hi
I have a partitioned table which has bitmap indexes on it.
Some of the bitmap indexes are giving datablock corruption error. Currently I am dropping the index and recreating it.
Is there any other way to resolve this issue?
Thanks.
What type of system is this - OLTP or Datawarehouse ?
Since you did not post the exact Oracle error received, lets try some educated guess. Are you getting this error:
ORA-01578: ORACLE data block corrupted (file # string, block # string)
Cause: The data block indicated was corrupted, mostly due to software errors.
Action: Try to restore the segment containing the block indicated. This may involve dropping the segment and recreating it. If there is a trace file, report the errors in it to your ORACLE representative.
Did you see if there was something more useful in the trace file (if created)?

How to overcome from Data block corruption error
Hi,
I am using one table when i was deleting one row, i encountered "Data block corruption error".
Kindly suggest solutions for the same.
Regards,
AbhishekIf you have a recovery manager backup, then you can perform a block recovery operation, after the information shown on the error message where the file# and the block# are displayed you can perform the block recovery operation.
Syntax for the block recovery operation can be found here : BLOCKRECOVER
In case of an index block, it is enough to rebuild the index.
In case you have a regular backup with archivelog enabled you can restore the damaged datafile and perform a simple file recovery operation.
One more additional tip that can be used, you may be interested in using the DBMS_REPAIR package unit.
Finally, I suggest you to check the complete datafile using dbv (Database Verifier) utility to find out if there are more corrupt blocks in your datafile, and proactively run this utility as a maintenance task.

Need advice on ORA-01578: ORACLE data block corrupted
We have a development database server version- 10.2.0.3 with materialized views refresh as complete every morning. Yesterday we had a power failure and the server went down and database was shutdown unexpectedly.
When we restarted the database after the server restarted, we found some of the datablocks got corrupted . Following were the exceptions that we saw in the alert.log.
Errors in file /i01_01/app/oracle/product/10.2.0/db_1/admin/orcl9/bdump/orcl9_smon_7547.trc:

ORACLE Instance orcl9 (pid = 8) - Error 1578 encountered while recovering transaction (9, 38) on object 54463
I tried the following query to see the segment type.
select owner, segment_name, segment_type from dba_extents where file_id =11 and 257712 between block_id and block_id + blocks - 1;
OWNER
SEGMENT_NAME
SEGMENT_TYPE
VISH
INVENTORY_TXN
TABLE
where " INVENTORY_TXN " is a materialized view that was using the block that got corrupted. I can always recreate the MV by dropping and recreating it. Will it solve the problem???
If not, how can I recover/repair the block.???
Can anyone advice on this. Thanks very much in advance.To recover a corrupted block,the best way out is to use Blockrecover command of RMAN. So you would need RmAN backup to perform the operation.But first ypu you need to ensure that this is a persistent error or not? Is this error is coming repeatedly or just once it happened?

Data block corrupted on standby database (logical corruption)
Hi all,
we are getting the below error on our DRSITE,it is MANUAL PHYSCIAL STANDBY DATABSE...
The following error has occurred:
ORA-01578: ORACLE data block corrupted (file # 3, block # 3236947)
ORA-01110: data file 3: '/bkp/oradata/orcl_raw_cadata01'
ORA-26040: Data block was loaded using the NOLOGGING option
I have checked in the Primary database, that there are some object which are not being logged into the redo logfiles.....
SQL> select table_name,INDEX_NAME,logging from dba_indexes where logging='NO'
TABLE_NAME INDEX_NAME LOG
MENU_MENUS NUX_MENU_MENUS_01 NO
MENU_USER_MENUS MENU_USER_MENUS_X NO
OM_CITY IDM_OM_CITY_CITY_NAME NO
OM_EMPLOYER EMPLR_CODE_PK NO
OM_EMPLOYER IDM_EMPLR_EMPLR_NAME NOOM_STUDENT_HEAD OM_STUDENT_HEAD_HEAD_UK01 NO
OT_DAK_ENTRY_DETL DED_SYS_ID_PK NO
OT_DAK_ENTRY_HEAD DEH_SYS_ID_PK NO
OT_DAK_ENTRY_HEAD IDM_DEH_DT_APPL_REGION NO
OT_DAK_ENTRY_HEAD IDM_DEH_REGION_CODE NO

TABLE_NAME INDEX_NAME LOG
OT_MEM_FEE_COL_DETL IDM_MFCD_MFCH_SYS_ID NO
OM_STUDENT_HEAD IDM_STUD_COURSE NO
13 rows selected.
so the main problem is in the OM_EMPOYER tables if i would delete the indexes from that table recreate it again with the logging clause,and then apply the archvied logs to the DRSITE.WILL THE problem will resolve.
Pls suggest me...Hi..
Firstly how did you confirm that it was that index only.Can you post the output of
SELECT tablespace_name, segment_type, owner, segment_name
FROM dba_extents WHERE file_id = 3 and 3236947 between block_id
AND block_id + blocks - 1;
This query can take time, if are sure that its the index don't fire this command .
Secondly, when you will drop and recreate the index, it will be logged into the redo logfile.This information will be be logged in to an the archivelog file as its the replica of the redo logfile. Then when you apply this archive log maually, it will drop that index and then recreate it using the same sql.

ORA-01578: ORACLE data block corrupted on tables in sysaux tablespace
Dear Experts,
From the alert log file we noticed data block corruptions on one of our datafiles. After further investigation, we realized that the corruptions were on 3 of the AWR related tables in the SYSAUX tablespace:
1. WRH$_LIBRARYCACHE
2. WRH$_TEMPSTATXS
3. WRI$_ALERT_OUTSTANDING
The bad news is that we may not have a valid rman backup to do the recovery due to the retention policy - RECOVERY WINDOW OF 2 DAYS. Since this is a development database with limited monitoring, we did not discover the corruption until 6 days later. The issue happened about 6 days ago (about Christmas time).
So, what are our recovery options? Can someone advice? We are thinking about drop and recreate the 3 affected v$WR* tables, but not quite sure about the impact to the system if we drop and recreate the 3 objects. Did someone experience this type of recovery. If you did, what are your approaches?
We are running oracle 10.2.0.3 version.
I greatly appreciate your input and suggestion. Thanks!!!as long as you have a backup of ur database before christmas, you can use the " MAXDAYS " cmd to get ur backup working so long as you have not used delete obsolote....had a same sistuation....where i had a backup and trying to restore it ...kept saying no valid backup...after going thru some stuff...found the MAXDAYS cmd to use my backup...here is an example ...

Impact on import if there is a block corruption error in exported dump file
Hi All
I got an exported file(exp utility) from production database and in the log it is showing the error
EXP-00056: ORACLE error 1578 encountered
ORA-01578: ORACLE data block corrupted (file # 29, block # 387036)
ORA-01110: data file 29: '+ORAFILES/prod/datafile/data.1750.715846723'
ORA-26040: Data block was loaded using the NOLOGGING option
There were two such errors. At the end of the export it is giving the message "Export terminated successfully with warnings"
I want to if I do an import using imp will there be any issues with the import.
will the import complete successfully.
The database version is 10.2.0.2.0
Regards,
Samrat
Edited by: Samrat Kumar on May 18, 2010 11:23 PMYou may try the import and hope it works out, but you and your DBA should address the ORA-26040 error message. Identify the segments that relate to both errors you encountered (using file id and block number) and figure out the what you may want to do if those are not index segments. Here is a link to a similar issue:
ORA-26040: Data block was loaded using the NOLOGGING option

ORA-01578: ORACLE data block corrupted
Dera Guru's,
In SAP i have following error in Oracle Database
SQL error in the database when accessing a table
"Database error text........: "ORA-01578: ORACLE data block corrupted (file #
38, block # 72576) ORA-01110: data file 38:
'K:\ORACLE\D01\SAPDATA4\D01_12\D01.DATA12'"
How can i resolve it.Please guide me...
Thank you for your help and advice....Error: ORA-01578 (ORA-1578)
Text: ORACLE data block corrupted (file # %s, block # %s)
Cause: The data block indicated was corrupted, mostly due to software errors.
Action: Try to restore the segment containing the block indicated. This
may involve dropping the segment and recreating it. If there
is a trace file, report the errors in it to your ORACLE
representative.
Do you already identify the object corrupted ?
What kind of backup do you have ?
Edited by: marcopb on Sep 10, 2012 2:47 PM -
I'm on 9i R2 Patch 7 on a Microsoft Windows Server 2003.
How do you fix data block corruption in a Table?
Is the some way to retrieve the data from the Table drop it then recreate and reimport the data?
or do you have to succumb with restoring the Database from the last known good backup?Hey, you can do the BMR (Block Media Recovery).
Since block corruption is to few subsets of blocks, i.e. a single table, you dont need to restore from the previous valid backup, you can simply do the following to achieve BMR.
Connect to rman and run the following:
run{ backup validate database};
Once the above commend is finishes, exit from RMAN and connect to the database as / as sysdba and use the following view to know the details required for BMR.
select * from V$backup_corruption;
The above queries gives you file# and block# information. Once you have the information do the BMR using following command at the RMAN prompt:
run {blockrecover datafile # block #};
# : indicated the datafile number and block number from the above view.
Let me know if you have any further issues.
You can also use view V$DATABASE_BLOCK_CORRUPTION to view the file# and corrupted blocks information.

Hi,
We are facing block corruption error file system file. I rtied to identify the corrupted object using dba_extents but that query is also giving the block corruption error for the same block. we are running the database in noarchivelog mode and we don't have backup.
please suggest the way how can i solve this corruption error?
Thanks in advance.

DATA BLOCK CORRUPTION : ORA-1578 해결 방법
제품 : ORACLE SERVER
작성날짜 : 2005-08-18
DATA BLOCK CORRUPTION : ORA-1578 해결 방법
=========================================
모든 오라클 데이타 블럭은 sequence 번호(seq)와 incarnation 번호(inc)를
갖고 있다. ORA-1578 에러는 seq=0 이고 inc <> 0 (새로운 블럭이 아님)일 때
발생한다. ORA-1578 에러는 ORA-600[3339] 에러와 함께 발생하곤 한다.
ORA-1578 에러가 발생하면 corruption이 발생한 화일 번호와 블럭 번호를
알려준다. 여기서는 이 때의 화일번호를 f, 블럭번호를 b 라고 부르기로 한다.
<해결 방법>
1) 우선 해야 할 일은 어떠한 오브젝트가 corrupt 되었는가를 알아내는 것이다.
다음의 스크립트를 이용하면 알 수 있다.
SQL>select segment_name, segment_type
from dba_extents
where file_id = f and
b between block_id and block_id + blocks - 1;
2) 만약 해당 세그먼트가 인덱스이면 drop 시키고 다시 생성하면 된다.
3) 만약 해당 세그먼트가 테이블이면 corrupt된 블럭의 데이타는 손상된 것이다.
4) 만약 해당 테이블이 들어있는 export 화일이 있다면 손상된 테이블을 drop
시키고 import 받는 것이 제일 간단한 방법이다. 하지만, 만약 export 받은
화일이 없거나 backup해 놓은 화일도 없다면 해당 테이블에 인덱스가 생성되어
있는 경우에 한해서 다음의 방법을 사용해서 복구를 하도록 한다.
5) 해당 테이블에 대한 인덱스가 생성되어 있다면 이를 이용해서 corrupt된
블럭을 피해갈 수 있다. 이 방법은 다음과 같다.
- empno, ename, deptno 를 컬럼으로 가지는 emp 테이블이 corrupt 되었다고
가정하자. 그리고, empno 컬럼에 인덱스가 생성되어 있다고 하자. 클러스터화
되지 않은 모든 테이블은 Unique한 rowid를 가진다.
rowid를 varchar2/hexadecimal 형식으로 표현하려면 rowidtochar 함수를 이용
한다.
SQL> select rowidtochar(rowid) from emp;
rowid는 총 18자로 block address(8자), dot(1자), row address(4자),
dot(1자), file address(4자)로 구성되어 있다.
SQL> select empno, rowid
from emp
where empno > 0
위의 스크립트를 실행시키면 다음과 같은 결과를 얻게 된다.
EMPNO ROWID
100 00000003.0000.0006
101 00000003.0001.0006
102 00000003.0002.0006
103 00000003.0003.0006
500 00000004.0000.000A
501 00000004.0001.000A
755 0000001A.0005.000A
756 0000001A.000C.000A
만약 인덱스가 character 컬럼에 대한 것이었다면 위의 query 문장을 다음과 같
이 바꿀 수 있다.
SQL> select empno, rowid
from emp
where empno > '';
예를 들어 다음과 같은 에러 메시지가 떨어졌다고 하자.
01578, 00000, "ORACLE data block corrupted (file # 10, block # 4)
그러면, 다음의 스크립트를 사용하여 손상된 블럭에 있는 employee 에 대한
empno를 구할 수 있다.
SQL> select empno from emp
where empno > 0
and rowidtochar(rowid) like '00000004.%.000A';
EMPNO ROWID
500 00000004.0000.000A
501 00000004.0001.000A
이제 emp 테이블과 같은 구조를 갖는 새로운 테이블을 만든다.
SQL> create table temp
as select * from emp
where 1 = 2;
그런 다음 손상된 부분을 피해서 새로운 테이블에 손상된 테이블의 데이타를
추가한다.
SQL> insert into temp select * from emp where empno < 500;
SQL> insert into temp select * from emp where empno > 501;
손상된 테이블을 drop 시키고 temp 테이블의 이름을 emp로 변경한다.
그리고, 백업된 자료나 문서 자료를 통하여 손상된 부분에 대한 정보를 추가한다.
6) 손상된 블럭에 여러 개의 row가 존재하고 있다면 다음의 방법을 이용한다.
SQL> create table empnos as
select empno from emp
where empno > 0
and rowidtochar(rowid) not like '00000004.%.000A';
이 스크립트를 이용하면 손상된 block에 포함되지 않는 empno들을 알 수 있다.
다음의 스크립트를 계속 실행시켜 복구를 한다.
SQL> create table temp as select * from emp where 1 = 2;
SQL> insert into temp
select emp.empno, emp.ename, emp.deptno
from emp, empnos
where emp.empno > 0
and emp.empno = empnos.empno;
7) 만약 Data Dictionary의 table이나 index에서 손상된 block이 발생했다면
지원을 요청해야 한다.Hi,
