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

Data Block Corruption

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.

DB Size: 10 TBs+
We had a SAN outage recently. The DB is back online. We want to check for block corruption to be on the safe side. We are planning to take a SAN EMC BCV copy of prod to run this. Looking for opinioms on the best way.Production is up and running. This is just a sanity check.
We are NOT using RMAN for backups. We do a BCV copy and then back that up and archive logs to tape.
RMAN: Can we do this from the control files? Do we have to set anything up? Is this the best way?
DBMS_REPAIR: I have not used this. We don't even have the package installed. I can install it.
DB_VERIFY: not sure if this is a good option or not. Is this current? I know I'll have to do it file by file and grep the logs. I have used this in the past, but its been a while.
Performance issues, CPU, I/O don't matter. We are doing a BCV copy and then mounting the DB on a new server.

Needs help regarding block corruption

DB Version - 11.2.0.3.0
Issue - Last backup failed due to block corruption ,message says "ORA-19566: exceeded limit of 0 corrupt blocks for file /GP/GAA01-N-P/db00/index01/GPEDWPR/bi_gpedw_fcct.dbf'

5. Contact Oracle Support Services if the preceding recommendations cannot be used, or if they do not fix the failures selected for repair
Now how to troubleshoot ? Any help will be highly appreciated

First, you need to determine to which segment the block is assigned:
select segment_type,owner,segment_name
from dba_extents
where file_id=58 and 3106752 between block_id and (blockid + blocks -1);
Your action from there will depend on the type of segment. Since you have no backup, the options are limited. But there are still possibilities.

11g Block Corruption Question..

Hello All,
I am running an 11g (11.1.0.7) 64 bit on a Redhat 5.3 host. I did an RMAN clone or copy of this database to another Redhat host, same file structure, DB version, identical to production. I am using 11g enterprise manager GRID control to manage this newly cloned host. When I try to perform a full-backup using the 11g enterprise manager grid control GUI, it tell me that I have block corruption in datafile#7 and lists all the blocks. Now, I know for sure that my production host (where the clone was made from) does not have any corrupt blocks of any sort. I also ran a 'validate database' and 'validate datafile 7' command on the newly created host and all reports back ok. The full backup completes successfully, but where is it getting this corrupt datafile 7 from? Can I clear this block corruption list somehow? Both Production and the newly created clone are free of any block corruption. When I execute an RMAN> backup database command on the newly created host, it fires off and does its thing, no mention of any block corruption, but when I want to perform a full backup with the GUI, it warns me of the block corruption - but lets the full backup continue and complete. GUI issue with 11g enterpise manager grid control?
Please advise..
Thanks,
RB

Its not mandatory that if you are getting the message of block corruption from GUI , it must be true only. Since you are using RMAN, if it can't find a buffer to read in few tries( 3 I believe) , it would mark the buffer as "corrupted" but that's NOT a corruption. As long as you don't see ora-1578 in the alert log repeatedly, you don't have a corruption. What more you can do is to run the command validate ....check logical to confirm that there is some logical corruption detected or not. Other than that, IMO you are fine.

Hi,
I am using Oracle 10g 10.2.0.1 with linux 32 bit
I wanted to check block corruption using RMAN by following statement

when i executed the statement, following was the output

and when i do the following query
select * from v$database_block_corruption in sqlplus
then there was no row
so it means there is no logical corruption, but when i am looking at alert log file it is giving following lines

Is it normal, why the in alert file it is saying that Error in.
And it did not create any backupset in folder of flash recovery but in Enterprise manager it is showing last backup on 09-may-2008, why ?
Regards,

See logical corruption is normally termed as the internal inconsistancy within the block which is not caused by Oracle but by the user.So if you find internal inconsistancy than the best option is to look at the user and ask him to get the values sorted out.If the internal inconsistancy is some thig like index fragmentation sort of things or index entry pointing to a null rowid than they are termed as the logical corruption and they should not impact your normal as he data is already there and there is no issue in reading the block as such.
The term "corrupted blocks" I would call both in the tables and backup for those data blocks which are unreadable by Oracle which actualy is Physical corruption.
If i am doing the checking at 2:00 am, does it take more than two hours.I didnt understand this.
what can we do for Physical corruptionThis will need the block to be recovered with the Block Recover command of RMAN and a good backup.Read about it here,

Immediate help can be only provided by Oracle Support Services. So if you need that, please raise a Sev1 SR . For your issue, as others have suggested already, if you have a valid backup and you are in the archive log mode, using RMAN's BMR(Block Media Recovery) , the issue can be resolved provided there is nothing wrong with the hardware of yours. If that's the case, recovery wouldn't yield any benefits.

Block corruption in undo_tablespace

due to storage problem my server changed to read only, because of this my database instance gets terminated improperly. after fixing storage issue i started the database it throws error as block corruption. that undo datafile is needed for instance recovery, so i can't able to make it offline.
main thing is my database is in noarchivelog mode.
Please give any solution to open the database except restoring.

How to respond to physical block corruption??

Hi, all.
As far as I know, there are two types of block corruption.
1. logical block corruption
2. physical block corruption
In case of logical block corruption, there are a few method of how to take care of it.
such as BMR with rman, media recovery, and dbms package.
In case of physical block corruption, how can I respond to this type of errors?
Does physical block corruption of a disk mean disk failure??
If so, I have to replace the disk? Or, is there any other way to solve
this type of errors?
In addition, how can I know that the block corruption is caused by logical problems
or physical problems??
Thanks and Regards.

> In case of physical block corruption, how can I respond to this type of
errors?
Round around in circles, screaming at the top of your voice "we're all going to die!".
Hey, why that funny looks? It works. And it scares the stuffings out of management and colleagues... ;-)
> Does physical block corruption of a disk mean disk failure??
If by physical corruption you mean that reading a data block results in I/O errors and a corrupt/incomplete read buffer, then yes. The "disk" is failing - or more correctly, the I/O h/w is failing. It may not be the disk itself. It could be a problem with the HBA, a controller card, etc.
In exceptional cases it may not even be a h/w issue. It could be a s/w induced error. I once got physical I/O errors reported by Oracle. The problem was traced to an incompatibility between the ASMlib kernel module and EMC Powerpath. The SAN disks & h/w were fine.
> If so, I have to replace the disk? Or, is there any other way to solve
this type of errors?
There should be some kind of diagnostics you can run on the disks to determine if they are failing. Simply replacing a disk because there seems to be a physical corruption problem may not solve the problem itself.
You need to identify the actual problem. Which means looking at all Oracle traces/dumps in this regard, looking at the kernel logs, manually dumping blocks to see the results, using whatever I/O & disk diagnostic tools available, etc.
> In addition, how can I know that the block corruption is caused by logical
problems or physical problems??
That depends on what you define as logical and physical corruption. The latter means to me that I cannot get the data off the disk without some kind of I/O error. Logical means that the data can be read just fine, but is garbage. Which could simply mean GIGO without implying any kind of underlaying h/w failure.
