I am backing up SQL 6.5 DB using Backup Exec 7.2 on NT 4.0 server SP4 with SQL server agent. The backup job ends in Failed status and a warning that DBname is corrupt. I then try to run DBCC Checkdb, newalloc, and checkcatalog commands to repair the DB. No further ahead yet. Are there any other commands that I can perform on the DB so that the corruption can be repaired, or verified there indeed is corruption of DB?

How to repair a corrupted OLAP database?
View 2 Replies View Related
Hi there.
I have a corrupt .sdf database sat on a SD Card but i am unable to find a way to repair it.
So far I have tried a few different methods, most of which just tell me what i already know i.e. "the database is corrupt and needs repairing!!"
I am unable to open the file in SSMS object browser (see above message) which means i cant run repair / shrink utilites.
I am also unable to add the database to a vs2005 project (again see above message) meaning again i can't run any repair utilities.
I have also tried using the compact / Repair utility in Query analyser 3.0 on my Windows Mobile 5.0 PDA but once again i am greeted with an "error reading file - Run the Repair Utility" Message.
Lastly i've tried using the SQLCEengine.repair method and, depending on whether i do it on the PDA or on a desktop pc it throws the exceptions "Error occurred reading database file - run the repair utility"(PDA) or "invalid database type" (PC)
Can anyone shed any light as to whether there is another (easier???) way of doing this or if i just have to face it that this file is lost?
Thanks
ps. the code i used for the .repair is as below:
Dim conn As SqlCeEngine
Dim strdb As String
strdb = "SD CardPathnameDatabase.sdf"
conn = New SqlCeEngine(String.Format("Data Source={0}", strdb))
If conn.Verify = False Then
conn.Repair(Nothing, RepairOption.RecoverCorruptedRows)
MsgBox("Successfully Repaired")
End If

I'm an Access man moving towards SQL Server and I'm interested in knowing if there is a utility for my SQL Server version 7 database that is similar to Access' Compact and Repair utility?

Running SQL 7, Standard version. I had a database marked 'suspect'. I copied the MDF and LDF files to another directory, then deleted the suspect database. I tried to create a new database and attach the MDF file to it. It did not work. Any other ideas? I have no other backups of the data. I am willing to pay for consulting over the phone if necessary.

View 1 Replies View RelatedIf we restore a database (full backup) first and continuously apply its transnational log backups, do we end up with two identical databases at page level eventually?
If so, page level repair to principle server may work as documented. I can see SAN level mirroring will give you exactly two identical databases at page level eventually at some point of time.
I can see Sybase device (in MS word file) level mirroring will give you two identical things at page level for same device.
But applying the transcriptional logs sequentially on the other servers, can SQL Server guarantee these two databases are identical at page level given there is server configuration can be different?

Hi all,
Long time ago, I downloaded the Northwind and pubs databases from the Microsoft website (I do not remember the details of it) and installed these two databases together into the SQL Server Management Studio Express of my PC (Microsoft Windows XP Pro). I tried to learn an example of using "User Instance" (source code was from a book) on the Northwind database located in my SQL Server Management Studio Express. I just find out that my Northwind database has the title only and no tables at all. If I click on the "+" in front of the "Northwind", I got the following error message:
Microsoft SQL Server Management Studio Express
Failed to retrieve data for this request.(Microsoft SqlServer.Express.SmoEnum)
Additional information:
One or more files do not match the primary file of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupted and should be restored from backup. (Microsoft SQL Server, Error: 5173)..
Please help and tell me how I can repair this Northwind database in my SQL Server Management Studio Express.

I deleted the name 'Northwind' in my SQL Server Management Studio Express, executed the "SQL2005DBScriptsInstnwind" program and I got the following error message: Msg 1802, Level 16, State 4, Line 1

Hi all,
Had a disk problem here, and all apps connected to our database hung. Nothing was responding, rebooted, and mssqlserver hangs on startup.
If i move the mdf and ldf files of the database in question to another folder, mssqlserver starts up ok, with the db marked as suspect.
It would seem the the mdf and ldf are corrupted.
I am restoring a backup from yesterday, but this will take hours.
Any suggestions trying to recover it as it sits?
Thanks in advance for any ideas.
I have a SQL 2000 database whose MDF is approx. 105 GB. Everything has been working fine for months until this past weekend when the database server dropped offline. I restarted the services and SQL server looks to have started up okay. However, trying to access it via Enterprise Manager causes EM to hang. Checking the Windows event log, there are a whole series of messages stating ...
3455 : Analysis of database 'ptportal' (7) is XX% complete (approximately 61 more seconds)
This 'analysis' ran for over 12 hours ... I have never seen this run before, much less this long. Now, there are a new series of messages stating ...
3450 : Recovery of database 'ptportal' (7) is XX% complete (approximately 56526 more seconds) (Phase 2 of 3).
This 'recovery' has been running for 9 hours now. Does anybody have any idea what has happened here or what is going on? My guess is that this database has been corrupted and SQL Server is trying to do a repair? Anybody know how long this usually takes and what the success liklihood would be?
Thanks

Hi,
Please Help, I am very desparate for a solution to this one.
I have an error appearing
"Error 25115 Wrong Page (potential database corruption). Try Running the Repair Utility."
I have SQL Server Enterprise set up with Merge replication, it is being used to Sync with Windows Mobile Devices as the subscribers.
All the Windows Mobile subscribers have been synchronising fine up until recently, when 1 of the Subscribing Windows Mobile devices received this error.
The day after, another device Synchronised fine the first time (note that the Synchronisation was a long one and the SDF grew in size dramatically while the synchronisation occured, but the Sync worked fine and the SDF dropped back to its initial size) The 2nd sync 5 mins later failed however so this Mobile device has the same error also.
Any suggestions as to the below are much appreciated
a) Why this error occurs?
b)How do you resolve this error?
c)What is the Repair utility mentioned in the error, and is it of use to me?
Thanks in advance, I am very greatful for any advice.

The following list of actions leads to a corrupt database on SQL Server 2005.
Create a database snapshot
Drop a table in the database
Backup the database
Restore from backup
Revert to the snapshot
I'm not entirely surprised that it results in a corruption, what is surprising is that I can revert from a snapshot after restoring. There needs to be some kind of check to prevent reverting to a snapshot in a case like this. Until SQL Server prevents you from doing it, I'd recommend a best practice is to delete all snapshots before you restore a database so that you cannot do this by accident.
I run MSDE on a Windows XP Server and my database was marked as "suspect" by Enterprise Manager and its icon become gray. I detach that database and try to re-attach it but there is an error as the following:
Error 3624:

Expression: rowLength >= offset + deleteLenght
SPID : 56

After that, I uninstall the MSDE and re-install new MSDE SP4 and try to re-attach the database file again and there is still an error. Is there anyway i can recover the data from that database?
We have repartioned a server (create a larger C-drive/system partition). It's about Windows Server 2003. Before repartioning SP2 was not installed. After repartioning checkdisk started automatically (as normal after using a disk partitioning tool). Checkdisk did some interesting and bad things with my files: changing file permissions and make some files corrupt, how I don't know. Something to do with SP2 not installed and the NTFS filesystem. After this action I have a corrupted SQL database. Tried to repair with the DBCC CHECKDB repair commands, but fail. Error in event viewer:
Error: 823, Severity: 24, State: 2
I/O error (bad page ID) detected during read at offset 0x0000003bdc4000 in file 'D:program filesMicrosoft SQL ServerMSSQLData352.MDF'.
I also still have NTFS errors in my event viewer. What to do? How can I repair the database? Only running checkdisk again? (and will this work?) Than all file security will be reset to Administrators.
Other ways to rebuild my database? (tools???) Unfortunally there isn't a good backup available due to a lack of good configuration of the backup software.
Let me start off by saying that under normal circumstance I would just restore from the last good backup. However in this case it appears as though the last good backup was sometime last August ... arg! After much yelling at the person responsible I've been attempting to get my blood pressure below 200 and see what data is recoverable.
First off, this was a RAID5 system that failed 1 drive. Secondly, before we got someone in there to replace said drive it failed a second drive and the system went down. We managed to massage the system back online but it appears that there is some corruption as a result which is no surprise.
I've done DB repairs in the past and it hasn't been too bad, but this time it is looking a little gnarly.
I've kicked everyone off the server and tried starting SQLServer several different ways.
I tried starting the service normally and then flagging the bad DB into single user mode with "ALTER DATABASE foo SET SINGLE_USER". I then did a select * from sysdatabases to make sure it took, which it did. I also tried starting the whole SQLServer in single user mode from the command line, "SQLServr -m".
I can run "DBCC CHECKDB('foo')" and I get a long ugly list of allocation errors. I posted it to a link as the 1349 lines returned is a little long:
http://chrisnet.net/sqlbad/dbcc_checkdb.txt
But when I attempt to bite the bullet and destroy data in an attempt to put things back together with:
"DBCC CHECKDB('foo', REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS"
I get:
Server: Msg 7919, Level 16, State 2, Line 1
Repair statement not processed. Database needs to be in single user mode.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
But yet the database is in single user mode, according to everything I check check on. Is this just SQL's way of telling me the corruption is too severe to be repaired? No output is displayed in the shell cmd window like it is for a successful DBCC either (when running sqlservr -m).
Ideas? Or do I put a bullet through it's brain?

A friend of mine called and said that his database was suspect and he detached it and was unable to attach it. The SQL Server Version is 2000 with the latest service packs installed. When I checked it the database (MDF) size was 1MB and the LDF size was 3.8 GB. I was not able to attach the two together and I was not able to attach the database using sp_attach_single_file_db. I did find an old backup of his database and attached that so he can work off of it but it is 1 yr old and he needs recent data. Since the MDF seemed to be blank we cant do much with that, but there seems to be data in the LDF. Is it possible to extract any data from the LDF file?

A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 3313, Level 21, State 2, Line 1
During redoing of a logged operation in database 'XXXX', an error occurred at log record ID (0:0:0). Typically, the specific failure is previously logged as an error in the Windows Event Log service. Restore the database from a full backup, or repair the database.
Msg 3414, Level 21, State 1, Line 1
An error occurred during recovery, preventing the database 'XXXX' (database ID 7) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support.

Iam not able to repair the corrupted Windows 2000 Advanced Serverinstallation but the file system is intact.
