LOG File Corrupted

Nov 14, 2007

We have one database of 5 GB of which when we take the backup and restore in another location, it says "Device Activation Error. The Physical file name e:databaseike_log.ldf may be incorrect".
The database has more than one log file.
Now when we use another procedure to create new database and stop the sql, then replace the old mdf file and REBUILDLOG. (Ie dbcc rebuildlog(nike,1,0)). It says incorrect DBCC Statment.

Pl. suggest us what to do?

Recover A Corrupted LDF File

Jul 20, 2005

Recently, one of our database's mdf and ldf was corrupted. We were able tobring back the database with the capability of importing and querying thedata. However, the data is not the full list. Some of the data are stillmissing because the tables we want still has sone 'chain mis linkage' errorwhen we did a DBCC checkdb/checktable. DBCC couldn't fix those errorseither. We're pretty sure that there are some data still burry under thecorruption. Then we thought of the life LDF file. This file should haverecorded every transaction up to the point of failure. So we trying torecover that file, but there are 2 problems. First is we don't have back upof that file and 2nd, that file is also corrupted. I couldn't backup thecorrupted ldf file at its current state. It's giving me some unrelated errormessage like disk space is out. All I know now is the only hope to recoverthose missing data are in this LDF file. We tried to use this software fromLimingent Log Explorer to recover it. So far no such luck with that. SoI'm asking anyone who has similar experience or problem. Please let me know.I need to know anyway to recover this LDF file, either by using sql server'snative tools or 3rd party tools. Any input is helpfull. thanks in advance.Wei

Database Corrupted, Need Help Recovering Data From LDF File

May 9, 2007

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?

Analysis :: Corrupted Aggregation File On Process Index?

Feb 8, 2012

I trying to update my Aggregation Design for a partition using BIDS Helper. The current aggregation design contains about 60 aggregations and the new aggregation I am trying to add is across 5 dimension attributes, the product of which is about 500,000 unique values. The fact table is about 13,000,000 rows.

When I deploy the aggregation and run ProcessIndex, I get the follow error:

File system error: The following file is corrupted: Physical file: ?E:Program FilesMicrosoft SQL ServerMSAS10_50.MSSQLSERVEROLAPDataTestDB.14.dbcube_2.607.cub
cubemeasuregroup_2.633.detDefaultPartition_2.579.prt852.agg.flex.data. Logical file.

If I remove the new aggregation, deploy, and run ProcessIndex again, it processes fine.

Is there some file size limitation I am running into? The agg.flex.data file is 7.8 GB before adding the new aggregation, so it isn't subject to the same 4 GB limit as .asstore.

DB Design :: Log File Corrupted While Making Database Readonly

Jun 3, 2015

We have database when trying to make read only throwing below error: with stack dump

Location:              recovery.cpp:4517
Expression:         m_recoveryUnit->IsIntendedUpdateable ()
SPID:                     51
Process ID:          6448
Msg 926, Level 14, State 1, Line 1
Database 'XXXX' cannot be opened. It has been marked SUSPECT by recovery.

See the SQL Server errorlog for more information.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.
Msg 3624, Level 20, State 1, Line 1

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.

Investigation DONE:

- DBcc checkdb shown Clean
- database is online and able to access
-Detached database and attached with rebuild log, still could not bring database read_only

SQL version : SQL server 2008 SP4.

Database Corrupted?

Jan 25, 2005

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.

Corrupted Database?

Dec 15, 2005

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

EM + QA Installs Corrupted

Mar 19, 2007

this may well be the wrong place for my post, if so please move it.

I have a variety of boxes with SQL tools installed on them. For some reason last week several of them seem to have gone a bit squif.

Server 1. Enterprise manager fails to run, giving message MMC could not create the snap-in. QA runs fine.

Server 2. Load EM click on a database and try Tools --> QA it comes back with File Not Found. Add isqlw as an external tool and you can run that ok, but still File Not found on the QA tab.

I know its not data corruption, but I hope someone can give me a clue on this!

Cheers!
