Old corrupted blocks in nologging mode.
Dear All,
I m facing issue of block corruption, when I check through select from v$database_block_corruption it shows total 511 blocks corrupted and below is one result. This are old one and not having backup for the same.
But when I validate the backup it shows no error. How to resolve this.....
FILE# BLOCK# BLOCKS CORRUPTION_CHANGE# CORRUPTIO
11 3638851 6 5.4254E+12 NOLOGGING
the RMAN backup validate to check block corruption will return if any ACTIVE DB blocks are corrupted or not. So to my knowledge the corrupted blocks u have are not being used by the DB for any read/write hence RMAN backup is not returning an information about the block corruption. The DBverify is an old version if RMAN did not find the corruption then DBVerify will also not return anything. So if RMAN des nt return any block corruption then you will not have any DB outage.

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.

Corrupt block detected in control file
Hi All,
I have a scenario where I have set up Active/Standby RACs and successfully have archive redo logs being applied to Standby - everything was ok
Versions - Oracle 11g R2 , of RHEL 5
Scenario 1:
Redo log application on Standby works perfectly when I do not create our software application tables using sql scripts on the Primary until AFTER the steps for Dataguard/RAC is completed successfully.
Scenario 2:
Redo log application does not work when I do run our sql scripts BEFORE I take a RMAN backup of the Primary to duplicate in the Standby
Everything comes up on the Standby after the rman duplicate, archive logs get transferred , but now they do not get applied.
I see the ORA-00227: corrupt block detected in control file: (block 1, # blocks 1) in the alert log when I put standby in Recovery Mode
My theory is that somehow our sql scripts are breaking my rman backups when I run them before creating an RMAN backup of Primary to load on Standby- I just need someone to advise whether this is a possibility from their experience, if so I will contact Oracle support to investigate further. This is my first time working on RAC DG etc
ThanksHi All ,
Ive tried to upgrade Oracle to 11.2.0.2 to fix this issue - that I can no longer remember !
Managed to complete upgrade on the standby node (after having to reinstall due to hostname change )
Now trying the Active node, I see the following error during the grid upgrade where i execute rootupgrade.sh
Now product-specific root actions will be performed.
Using configuration parameter file: /opt/app/11.2.0/grid2/crs/install/crsconfig_params
Creating trace directory
Failed to add (property/value):('OLD_OCR_ID/'-1') for checkpoint:ROOTCRS_OLDHOMEINFO.Error code is 256
The fixes for bug 9413827 are not present in the 11.2.0.1 crs home
Apply the patches for these bugs in the 11.2.0.1 crs home and then run rootupgrade.sh
/opt/app/11.2.0/grid2/perl/bin/perl -I/opt/app/11.2.0/grid2/perl/lib -I/opt/app/11.2.0/grid2/crs/install /opt/app/11.2.0/grid2/crs/install/rootcrs.pl execution failed
I have to download this patch from MOS for bug 9413827, somehow apply it to the old version of grid 11.2.0.1 and then rootupgrade.sh -
FullOffline Backup - ORA-19566: exceeded limit of 0 corrupt blocks for file
Dear SAP gurus,
I am getting an error from the DBA Planning Calendar every time the job for "Full Offline backup" is run. And it is always as you can see from the log on the same file "oracle/SHD/sapdata4/sr3_16/sr3.data16".
The oracle error is the following:
ORA-19566: exceeded limit of 0 corrupt blocks for file /oracle/SHD/sapdata4/sr3_16/sr3.data16
I found the SAP Note 969192 - RMAN Backup of SYSTEM tablespace terminates with ORA-19566
but it does no apply because this is for the tablespace SYSTEM and not PSAPSR3.

Logically corrupted blocks in standby
Hi
Assume I have a primary database and standby database.
Accidentally, Some of the objects (indexes and tables) are in nologging mode in primary database.
Force logging is not set.
When I scan the datafiles in standby I realize that some datafiles are logically corrupted because of this issue.
How can I get rid of these corrupted blocks?
If I rebuild indexes with logging option, and recreate table as logging,
Will it solve the problem? or any other suggestion
Many thanksSivok wrote:

Many thanksyour primary should run in force logging mode (ALTER DATABASE FORCE LOGGING) then the object level setting is ignored for direct path operations. You can apply an incremental backup to the standby to catchup (or just recreate the standby which might be as quick depending on volumes).

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 SelvanPalani,
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

Hi
1-)
If the database in noarchivelog mode I cannot issue:
Rman>
BACKUP VALIDATE DATABASE;
Since this command just checks if there is any corrupted blocks, and doesnt take backup, why it wants archivelog mode ?
2-) If I want to search corrupted blocks is there any diffrence among using
RMAN> BACKUP VALIDATE DATABASE;
or
dverify
or
analyze ... validate structure ;
P.S:noarchivelog mode.I read the link
The thing is I dont want to specify one by one all datafiles.
I want to scan all datafiles automatically? What if I have more than 700 datafiles?
Is that possible with dbv? -

Alter index ... rebuild was failing - getting corrupt blocks
Database: 9.2.0.5
OS: HPUX-ia64
Hello,
i rebuilded a index, announced from UpdatStats in DB13, and get a ORA-01114: IO error writing block to file 2045 (block # 319154) and
ORA-27072: skgfdisp: I/O error in my sqlplus session.
-> i do a alter index SAPR3."xxx~0" rebuild online parallel 4 nologging;
-> System was up and running
After that, the DBVerify marked some blocks corrupt, here one example:
BR0398E DBVERIFY detected corrupted blocks in /oracle/XXX/sapdata22/btabi_95/btabi.data95
We checked all corrupted blocks - all in free space.
So we fixed that with creating a table with next extend size from the corrupted blocksize.
I think we had not enough space in the tablespace where the index is, okay ... and what we also found, the PSAPTEMP datafiles was created as SPARSE files ...!!
-> PSAPTEMP-Datafile: 10GB in the System - 2,5GB maximum on OS-Level, no more space.
But my question is why i am getting corrupt blocks when a "alter index ... rebuild ..." is failing ?!?!
Thank you for your support.

Markus

I cant find any "cor" entries in the last DBVeriy log.
I think (hope) we dont' have anymore corrupted blocks in the system.
We get a response from SAP to update to 9.2.0.8.
My customer wanna do a update to oracle 10 in march/april 2009, so he send me the question if we need a update to 9.2.0.8 ASAP or can we wait for the update to oralce10.
But the important question from my customer and me is, why we get corrupt blocks after failing the alter index rebuild?

Do I restore the old phone? What should I do?
it now says the old phone is in restoration mode and to restore iPhone.
Hmmm...
That's a doozy. I'll have to think on that for a bit.
Quite perplexing indeed. A quandary you could say.
Not really sure what you could try...
Have you tried anything yet? -
My macbook pro hard drive went bad and i bought a new one and installed it. Now i have the old corrupted hard drive in my hand and i am looking to recover my files from it, any suggestions please? too bad i never backed them up.
After you have installed the OSX on the new HDD in your MBP, install the old HDD in an enclosure and connect it to your MBP via USB. Then try to drag and drop your data to the new HDD.
If this proves unsuccessful, you may look for data recovery software on the Internet. There will be free trails to see if it will work or not. If the trial suggests that it will work, then you will have to purchase the software.
The last resort is a professional data recovery service that will offer NO guarantees and charge a lot of money.
As you now can appreciate, backups eliminate such predicaments.

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

've gotten 60 or 70 messages that that my iCloud doesn't work and to select preferences. The message says I will get an email to verify but I never get an email. I've checked old email, blocked email, and have low filters on emails. Any ideas?
Hey CarolinQc,
Thanks for the question. The symptoms you are experiencing can result from an Apple ID address that has been changed prior to signing out of all of the services. Before you change the email address associated with your Apple ID, you’ll want to sign out of all services to avoid this. As a fix, you can temporarily change your Apple ID back to the old address:

Change your Apple ID temporarily
If signing out and back in to iMessage or FaceTime didn't help, try these steps:
1. Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
2. Go to Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:
- Scroll down and tap Delete Account, then tap Delete to confirm.
- Tap “Keep on My [Device]” or “Delete from My [Device].” In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
- Enter the password for your previous Apple ID.
3. Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.
4. Return to Settings > iCloud and sign in with your new Apple ID.
