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:
ORA-01578: ORACLE data block corrupted (file # 11, block # 257712)
ORA-01110: data file 11: '/i01_01/app/oracle/product/10.2.0/oradata/orcl9/ts_gen_data_02.dbf'
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?
About Blockrecover command,read here,

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 ?

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 ...

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

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.

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)? -
DATA BLOCK CORRUPTION : ORA-1578 해결 방법
제품 : ORACLE SERVER

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,

Oracle 10g + VMware Workstation 6.5 = data block corruption?
I'm trying to run Oracle 10g on VMWare Workstation 6.5 (host and guest are windows 2003)
I've noticed a couple times that I easily get block corruptions and wonder if there are some settings to lower the risk.
Note this is a DEV machine, not a production machine.
I don't know if Oracle supports the set up but I'm sure many people are running Oracle in Vmware so I'm looking to those who have done so successfully.
Anyone know of special precautions in either Vmware or Oracle config to limit the risk on block corruption?
According to VMWare, ESX is a perfect platorm so maybe I should move from Workstation to ESX, maybe it has to do with Windows in VM and Linux would work better.
Anyone has some info on why Oracle has block corruption on VMware Workstation (windows/windows)?
Other people with positive/negative experience on VMWare Workstation (mention OS's and Oracle version please)
(before someone tells me it's not supported, also see these pages on vmware.com:
http://blogs.vmware.com/performance/2007/11/ten-reasons-why.html
http://blogs.vmware.com/oracle/2009/03/a-perspective-support-for-vmware-with-oracle.html)
Edited by: phmeert on Feb 26, 2010 4:27 PMWell, it's indeed not for production, I use it for product demos and small development tasks, there is no critical data in my database but I wished I could run Oracle inside a VM on my laptop...
It works reasonably well (I even have run multiple VM's (Workstation) with Oracle insde on 1 laptop (4 GB Ram, Core Duo), but sooner or later it gives some problems. If there is any setting that can lower the risk would be great.
I was thinking of installing ORacle VM but apparently my laptop is not compatible with that (nor with ESX for that matter).
Anyone use plain Xen (which seems to support any processor) + Oracle on Linux ??
I can't install Oracle natively on the machine directly since I need the capabilities of a VM in respect of easy backup + I have many different applications and databases so depending on what I need to show, I just start a different VM
The VM provides the capabilities to move back to previous situation, exchaning demos with collegues, have multiple parallel copies with different configurations (depending on customer), etc...
... installing natively is too much of hassle, we used to swap hard disks but that's a pain when the hardware changes, at least with VMWare WS you can run it on pretty much any computer.
How do other people deal with this type of situation?? We have ESX on a hosted environment but internet access is not always available...
It seems stable enough to run my demos (I'm doing this for quite a while but the block corruption seems to happen sooner or later)
The problem is that I first need to get the demo installed without corruptions. Once it's installed I can just restart from that situation over and over again, but obviously I don't want to run the risk of having a disk corruption in the middle of a demo. -
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.

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.

How create data block corruption for test DBMS_REPAIR
Hello to all
I wanna create data block corruption in a table for testing Dbms_repair
is it possible ? if yes please say to me how I can do it ,by example please
thanksthank you so much that link was helpful (specially it's last respond)
I could create data block corruption and I tested DBMS_REPAIR and RMAN for data block recovery
but now I got head spin that if we have rman backup from database so using dbms_repair is what for?
while we can recover corrupted data blocks
please guide me

Query Execution/Elapsed Time and Oracle Data Blocks
Hi,
I have created 3 tables with one column only. As an example Table 1 below:
SQL> create table T1 ( x char(2000));
So 3 tables are created in this way i.e. T1,T2 and T3.
T1 = in the default database tablespace of 8k (11g v11.1.0.6.0 - Production) (O.S=Windows).
T2 = I created in a Tablespace with Blocksize 16k.
T3 = I created in a Tablespace with Blocksize 4k. In the same Instance.
Each table has approx. 500 rows (So, table sizes are same in all the cases to test Query execution time ). As these 3 tables are created under different data block sizes so the ALLOCATED no. of data blocks are different in all cases.
T1 = 8k = 256 Blocks = 00:00:04.76 (query execution time/elapsed time)
T2 = 16k=121 Blocks = 00:00:04.64
T3 = 4k = 490 Blocks = 00:00:04.91
Table Access is FULL i.e. I have used select * from table_name; in all 3 cases. No Index nothing.
My Question is why query execution time is nearly the same in all 3 cases because Oracle has to read all the data blocks in each case to fetch the records and there is a much difference in the allocated no. of blocks ???
In 4k block size example, Oracle has to read just 121 blocks and it's taking nearly the same time as it's taking to read 490 blocks???
This is just 1 example of different data blocks. I have around 40 tables in each block size tablespace and the result are nearly the same. It's very strange for me because there is a much difference in the no. of allocated blocks but execution time is almost the same, only difference in milliseconds.
I'll highly appreciate the expert opinions.
Bundle of thanks in advance.
Best Regards,Hi Chris,
No I'm not using separate databases, it's 8k database with non-standard blocksizes of 16k and 4k.
Actually I wanted to test the Elapsed time of these 3 tables, so for that I tried to create the same size
tables.
And how I equalize these is like I have created one column table with char(2000).
555 MB is the figure I wanted to use for these 3 tables ( no special figure, just to make it bigger than the
RAM used for my db at the db startup to be sure of not retrieving the records from cache).
so row size with overhead is 2006 * 290,000 rows = 581740000(bytes) / 1024 = 568105KB / 1024 = 555MB.
Through this math calculation I thought It will be the total table size. So I Created the same no. of rows in 3 blocksizes.
If it's wrong then what a mes because I was calculating tables sizes in the same way from the last few months.
Can you please explain a little how you found out the tables sizes in different block sizes.Though I understood how you
calculated size in MB from these 3 block sizes
T8K =97177 BLOCKS=759MB *( 97177*8 = 777416KB / 1024 = 759MB )*
T16K=41639 BLOCKS=650MB
BT4K=293656 BLOCKS=1147MB
For me it's new to calculate the size of a table. Can you please tell me then how many rows I can create in each of
these 3 tables to make them equal in MB to test for elapsed time.
Then I'll again run my test and put the results here. Because If I've wrongly calculated table sizes then there is no need to talk about elapsed time. First I must equalize the table sizes properly.
SQL> select sum(bytes)/1024/1024 "Size in MB" from dba_segments> 2 where segment_name = 'T16K';
Size in MB
655
Is above SQL is correct to calculate the size or is it the correct alternative way to your method of calculating the size??
I created the same table again with everything same and the result is :
SQL> select num_rows,blocks from user_tables where table_name = 'T16K';NUM_ROWS BLOCKS
290000 41703
64 more blocks are allocated this time so may be that's y it's showing total size of 655 instead of 650.
Thanks alot for your help.
Best Regards,
KAm
