Oracle Corrupted Blocks .

Hi ,
We using R/3 4.7 with Oracle 9.2 , Now i want to check any corrupted blocks are attected in our server , Can you tell me how can i check . Because i want to check the corrupted blocks in database is in online . Shall i use DBVERIFY .
Regards
Palani Selvan

Palani,
Yes You can use DBVERIFY. You can run it from DB13-->Verify Database
Check below note for details
Note 23345 - Consistency check of ORACLE database
SAP Note 354293 - DBVerify reports corrupt block in freespace area
Note 365481 - Block corruptions
Note 923919 - Advanced Oracle block checking features
Just for your information, in BW system If you get warning like "DBV-00200: Block, dba 97446680, already marked corrupted", it occures because secondary indexes of InfoCube fact
tables are set up in mode NOLOGGING as a standard.
See below notes for more information
Note 442763 - Avoid NOLOGGING during the index structure (Oracle
Note 547464 - Nologging Option when creating indexes
Note 849485 - Reconstruction of the NOLOGGING indexes after recovery

Hope it help

Oracle 11g: Block Corruption in SYSAUX File

Hello All,
I am facing Data corruption issue in the SYSAUX file.
We are using Oracle 11G (Microsoft 32 bit) and our system is running in noarchivelog mode.
Following are the errors in the alert log.

Drop and re-creating the index would be better than re-building the index.

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,

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 ?

it's experimental - so I do not run archives -
Designer on W95 crashes quite often but this should never lead
to corrupted data blocks.
Linux was hanging too - and disk-cache might not have been

Please check first /var/log/messages for any linux errors. It is
likely that if linux crashes and cannot sync to disk that there
might be some corruption problems. For this reason lts of people
would like to see raw device support but apparently Linus is not
willing for some reason...
I assume some hardware relevant problems though

Dear satish kandi,
recently we have created index for one table with nologgign option, i think for that reason i am getting that error.
if i run dbv utility on the files which are shown in alert log file i am getting the following results.

My doubts are :
1.if i drop the index and recreate the index with logging option will this error won't repeat in alert log file
2.in future if i activate the standby database will database is going to open without any error.

ORA-19566: exceeded limit of 999 corrupt blocks for file

Hi All,
I am new to Oracle RMAN & RAC Administration. Looking for your support to solve the below issue.
We have 2 disk groups - +ETDATA & +ETFLASH in our 3 node RAC environments in which RMAN is configured in node-2 to take backup. We do not have RMAN catalog and the RMAN is fetching information from control file.
Recently, the backup failed with the error ORA-19566: exceeded limit of 999 corrupt blocks for file +ETFLASH/datafile/users.6187.802328091.
We found that the datafiles are present in both disk groups and from the control file info, we got to know that the datafiles in +ETDATA are currently in use and +ETFLASH is having old datafiles.
RMAN> show all;
RMAN configuration parameters for database with db_unique_name LABWRKT are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 4 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+ETFLASH/CONTROLFILE/snapcf_LABWRKT.f';
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+ETFLASH/controlfile/snapcf_labwrkt.f';
Above configuration shows that SNAPSHOT CONTROLFILE is pointing to +ETFLASH. So I changed the configuration with the SNAPSHOT CONTROLFILE points to '+ETDATA/controlfile/snapcf_labwrkt.f'. At the end of backup, SNAPSHOT file was created in +ETDATA and I was expecting it to be the copy of control file being used which has dbf located in +ETDATA. But still the backup was pointing to old datafiles in +ETFLASH. Since we dont have RMAN catalog, resync also is not possible.
When I ran it manually, it was successfull without any error and was pointing to the exisiting datafiles.
RMAN> backup database plus archivelog all;
I hope the issue will get resolved if the RMAN points only to the datafiles present in +ETDATA. If I am correct, please let me know how can i make it possible? Also please explain me why the newly created snapshot file does not reflect the existing control file info?

Hi,
I am getting an error from the DBA Planning Calendar every time the job ...
So when was your last successfull backup of this datafile. Check if still available.
If this is some time ago, and may be you are currently without any backup, try to backup without rman at once,
to have at least something to work with in case you get additional errors right now.
Then you need to find out what object is affected. You are on the right way already. You need the statement,
that goes to dba_extents to check what object the block belongs to.
Has the DB been recovered recently, so the block might possibly belong to an index created with nologging ?
(this could be the case on BW systems).
If the last good backup of that file is still available and the redologs belonging to this backup up to current time are as well, you could try to recover that file. But I'd do this only after a good backup without rman and by not destroying the original file.
If the last good backup was an rman backup, you can do a verify restore of that datafile in advance, to check if the corruption is really not inside the file to be restored.
Check out the -w (verify) option of brrestore first, to understand how it works.
(I am not sure it this is already available in version 7.00, may be you need to switch to 7.10 or 7.20)
brrestore -c -m /oracle/SHD/sapdata4/sr3_16/sr3.data16 -b xxxxxxxx.ffr -w only_rmv
You should do a dbv check of that file as well, to check if it gets more information. I.E if more blocks are
affected. rman stops right after the first corruption, but usually you have a couple of those in line, esp. if these are
zeroed ones. (This one would also work with version 7.00 brtools)
brbackup -c -u / -t online -m /oracle/SHD/sapdata4/sr3_16/sr3.data16 -w only_dbv
Good luck.
Volker

Its not a corrupted block but a fractured block and also the object is not there anymore. So there is nothing that you are supposed to do.

Corrupt blocks with RH6.2 and 8.1.7

Hi
We have following problem: while running Oracle 8.1.7 on a Compqa DL580 with Smartarray controller 5304 on RedHat 6.2 system we encounter corrupt data blocks after a certain time.
We can see corrupt data blocks e.g after reboot, but also during normal operation. This happens again and again after some weeks after we had reinstalled the database. Oracle support lead us to install RH6.2 (after having the problems on 7.1), but it crashed again ...
Any tips?
System details:
kernel 2.2.19-6.2.7
glibc 2.1.3-22
mount 2.10r-0.6.x
fs.file-max=8192 (in /etc/sysctl.conf)
Dietmar

Hi
I work with linux RH (6.2, 7.0, 7.1) and 8i (8.1.5 since 8.1.7.0.1) and 9i and I only two times I find just a block corruption warning, but database keeps working fine.
This data corruption affects only Oracle? You can turn extra CRC check into oracle data blocks (of course it slows all process ;)
Maybe the linux RAID drivers have some bug, a simple solution is to install one datafile of the tablespace in a nother disk (IDE for example) and check if this datafile is corrupted too.
Anyway just make a simple script (using dd or random) or C, Perl.. program that writes/reads intensively (one week ir more) "1" on a big file (at least 1G) and check if you get some error. Oracle just calls system I/O, so if one crashes, other must too.

I don't so many trace files to be gerated . Can i do something .
Please help me.Dear Vivek. If you have used DBMS_REPAIR package, it means that you've marked those blocks corrupted and ORacle will bypass those blocks in I/O
Why you haven't used RMAN Block Media Recovery? You can watch my video tutorial on this: http://kamranagayev.wordpress.com/2010/03/18/rman-video-tutorial-series-performing-block-media-recovery-with-rman/
(And please don't tell me that you haven't taken RMAN backup if it's not a production database)
It's just a informatino written to the trace files that Oracle bypasses those data blocks
