Ora-01578 data block got corrupted
hi folks,
im running oracle9i and using VB6.0 as my front-end. suddenly in my application i got the above error and after a couple of minutes everything is fine.
i would like to know from the guru's and pandits of oracle why this error occurs and what is the best solution to avoid these type of errors in future.
thanks to one n all
have a nice day n night as well
First you need to find out the corrupted block details using available different methods, that is, ANALYZE, DB_VERIFY, DBMS_REPAIR, DB_BLOCK_CHECKING etc., and correct or repair the data block corruption
For more details on how to detect and repair the data block corruption, take a look at the below Oracle Documentations.

Data blocks are corrupted : Error ORA-01578
Hi All,
We having a serious problem with the oracle running in our development server.
Data blocks are corrupted with the error ORA-01578
and we have identified the segment as an Table TBTCO.
Hence can any body suggest us the way to resolve this.
Currently we dont require any data from that table. In that
case can we drop down the table and import it again with
the same table downloaded from production server?
As we dont have any oracle DBA's please suggest us the way to resolve this.
Please advise.
Thanks & Regards,
DVRKHey,
if you are using RMAN backup you can restore and recover only the corrupted blocks.
For more information take a look at that nice blog article from Lars:
Some hints to make handling of oracle datablock corruptions more efficient
If you don't have any idea howto handle this situation, please open a SAP call.

Ora-26040 : data block was loaded using the NOLOGGING option
i have restored full back up database using RMAN sucessfully from one server to another .Restoration process do not contain any error.
New Database contain job when it executes then it leaves mesaage in alert log.
"ORA-01578 oracle data block corrupted file # 6 block # 6888812"
"ORA-26040 data block was loaded using nologging option".
please let me know how it could recovered and prevented.
regards
prabhatIn short, your full backup has happened when a NOLOGGING transaction was on flight. Hence the recovery process should get the transaction's data out of archive logs. BUT the data doesn't exist in archivelog beause the transaction was NOLOGGING. For comprehensive detail read the documents above.
To prevent this situation, backup the database when no NOLOGGING transaction is running. -

This is the beginning of the data block dump. The first line tells us that we are dumping file#3, starting at block# 10 (minblk), and finishing with block# 10 (maxblk). Had we dumped more than one data block, these values would represent a range. The relative data block address (rdba) is 0x00c0000a. For more information on the rdba, refer to a later section in this paper. At the end of this line, we can see in parentheses that the rdba corresponds to file# 3, block# 10 (3/10).
The third line describes the SCN of the data block. In our case, the SCN is 0x0000.00046911. The tail of the data block is composed of the last two bytes of the SCN (6911) appended with the type (06) and the sequence (02). If the decomposition of the tail does not match these three values, then the system knows that the block is inconsistent and needs to be recovered. While this tail value shows up at the beginning of the block dump, it is physically stored at the end of the data block.
The block type shows up on the fourth line. Some of the valid types correspond to the following table:
Type Meaning
0x02 undo block
0x06 table or index data block
0x0e undo segment header
0x10 data segment header block
0x17 bitmapped data segment headeri hope it will help... -
Hello,
We had a SAN crash last month and with all the confusion I missed that we had some bad blocks after the crash. Our RMAN backups have now aged out so we don't have a RMAN backup. What I do have is a datapump backup from before the event. This is table corruption. Is there a way to either restore the table to a stage location, catalog the table or datafile somehow, then restore the bad block? Otherwise, somehow determine the bad data and get the data from the backed up table and insert it back into the bad table after I re-recreate it without the bad blocks?
Oracle support is just saying recreate the table skipping the bad blocks but there has to be some way here if the data is on that datapump backup that I can determin what it is then restore it.
ThanksThe fix blocks procedure did not work and I have not attempted the skip blocks. If I run the skip corrupt blocks will my query work? Is that worth a shot next?

<b>If the datafile get corrupted while creating, what should I do?</b>
Hi
During creation of datafile, if the datafile got corrupted then you can delete the data file and recreate it again. The condition is that the particular data file has not been used after creation.
But if the datafile is created snd used, then you have to restore the datafile from the backup (use the Brtools to restore the datafile)
Please use Brtools utliity for the same.

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.

Hi,
I was trying to collect schema stats. The system occurred with ORA-01578 error.
ORA-01110: data file 7: 'M:\ORADATA\PRODORCL\DATAMDM01.DBF'
ORA-26040: Data block was loaded using the NOLOGGING option

ORA-06512: at "SYS.DBMS_STATS", line 13249

I was trying to do:
SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS') FROM DUAL;
begin
dbms_stats.gather_schema_stats(ownname=>'DBA',estimate_percent => 10,method_opt=>'FOR ALL COLUMNS SIZE 1',cascade=> true);
end;
ThanksI do understand, but I have dealt with block corruption. Can you please tell me how to fix this.
I have gone through couple of documents and tried:
set serveroutput on
declare corr_count binary_integer;
begin
corr_count := 0;
dbms_repair.CHECK_OBJECT (
schema_name => 'DBA',
object_name => 'INVENTORY',
partition_name => null,
object_type => dbms_repair.table_object,
repair_table_name => 'REPAIR_TEST',
flags => null,
relative_fno => null,
block_start => null,
block_end => null,
corrupt_count => corr_count
dbms_output.put_line(to_char(corr_count));
end;
it shows :
6226
but when I do:
set serveroutput on
declare fix_count binary_integer;
BEGIN
fix_count := 0;
dbms_repair.FIX_CORRUPT_BLOCKS (
schema_name => 'DBA',
object_name => 'INVENTORY',
partition_name => null,
object_type => dbms_repair.table_object,
repair_table_name => 'REPAIR_TEST',
flags => null,
fix_count => fix_count
dbms_output.put_line(to_char(fix_count));
END;
it shows:
0
but it should be show the same 6226.
Can you please tell or provide doc for fixing this?

ORA-01578 about standby database in read only mode
Hi,
I have an ORA-05178 (data block corrupted) about a standby database which in read-only mode. About production database, there is no problem.
After analyze, this is an index segment :
SELECT segment_name , segment_type , owner , tablespace_name

WHERE file_id = 58
AND 218173 BETWEEN block_id and block_id + blocks -1
SEGMENT_NAME SEGMENT_TYPE OWNER TABLESPACE_NAME

There is no constraint.
How can I repair this problem ?

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.

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,

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 ...
