I run a daily maintaince job and it fails.But when i go through the error log. i get
this eror "'Table Corrupt: Extent id 30464 on allocation pg# 30464 has objid 732178004 and used bit on, but reference bit off"
how do i get the table name fron sysobjects as i have had no luck when i do a simple select query to get the details i need
Getting the name would make it easier to solve the problem
thanks

I have a table that I can't read any data.
It hangs up when I try to drop it as well.
So, what are my options here? Secondly, what has caused this?
Hi,
One of my tables got corrupt and it is not possible to bring down the Database into Single user mode to run the dbcc to repair it. Is there any other way that I could correct.
Thanks

I have a problem for dropping a table from my database and I got the error message: ""Extent chain for object 736005653 is not correctly linked." The problem indicates table corrupt on the database from DBCC checknewalloc. Instead of reloading the database from a dump, do you have anyway to repair the damage table or drop it.
TIA,

View 1 Replies View RelatedI have small table that has been corrupted.
I'm getting the following error when running a simple select statement:
"could not open FCB for invalid file ID 0 in database 'data_base_name'.
Table or database may be corrupt. connection broken."
I have already created a new table, but I have been unsuccessful at removing the corrupted table. Does anyone know the steps to go about removing this table? And, if anyone has seen this type of error before, why did it occur?
Is it a bug with microsoft SQL7? Any info would be greatly appreciated.

Hi Everybody,Can any one tell me how to solve the error 8908(Table Corrupt error). Iam getting this problem every 6 weeks or so. Chain linkage mismatch problem.Help in this regard is highly appreciated.Thanks in advance.

Folks,
I am running SQL 7.0 & SMS 2.0. I get the following message while running DBCC CHECKCATALOG on my SMS database.
"Table Corrupt: Object ID 322100188 (object 'Summarizer_ComponentTallys') does not match between 'SYSREFERENCES' and 'SYSCOLUMNS.'."
This prevents my nightly tape backup as well.. Veritas (Backupexec) nightly as well. Is there a fix for this? This has been happening since we installed SMS 2.0 sometime in December.
Thanks.

Hi folks,
on one of my SQL7.0 Servers I sometimes encounter the following message in the errorlog:
Table Corrupt: Object ID 0, index ID 0, page ID (1:999816). The PageId in the page header = (0:0).
It seems to me that this message is put for each db that is delt with in the maintenance plan, because it is the same number (16 times in my case)
It occurs during the index reorganisation phase of my maintenance plan. Before this happens there is a DBCC checkdb and DBCC newalloc on several DBs with no errors.
Anything I have to check or to fix, or can I ignore such zero-messages?
Thank you in advance

I have a corrupt syscolumns table and have no good backups :(
I get message 7930, Level 16, State 1.
Table Corrupt; keys in left child is not less than the parent key; check left child page 15491....
The end result is the appearance that a column is missing from one of my tables. In otherwords, I know the table is supposed to have col1, but when I select data from the table, col1 does not show up....dbcc checkdb gave me the error above.
thanks in advance!

Hi there!
I need to execute: ALTER DATABASE MyDB SET SINGLE_USER
which always returns Timeout Expired.
I can't execute dbcc checktable (MyTable, REPAIR_ALLOW_DATA_LOSS) until the database is in single mode.
How else can I set single-mode or can I bypass that requirement?
Thanks!

I have a table which I am unable to drop, remove indexes from, and when I select the database from the EM and click on Recalculate get the following error:
When attempting to do a Recalculate from the EM I get: Error 2541 (SQL Server) Table Corrupt object id does not match between extent in allocation page a d sysindexes; check the following extent; alloc pg# 589050 extent# 589096 object id on extent=0 object name=0 object id in sysindexes=1420532094 (object name=MifDEtailOct)

When attempting to drop the table from the EM it disappears then when I do a refresh it's back again.
I run a checkdb on the database once a week, but that hasn't resolved the problem.
I also ran the sp_fixindex as outlined in the faq with no relief.
This initially happened on one table and now I'm getting the same error on a second table. I have removed the data from both tables, but can't seem to get rid of them.
These tables originally has a couple of million records in them so they were rather large before I moved the data to a new table.
Truncate also didn't work when I was attempting to clear the table. I had to create an sp to delete a few hundred thousand records at a time.
I would appreciate any suggestions.

I have SQL 2005 with sp1 (can't get sp2 to install yet), with a failover cluster (that works, but hasn't needed to be used in awhile), and the data resides on a, new, 1TB SAN array.
We were not aware one of our tables were corrupt until the last rotation of our backup included the corrupt table. So restoring isn't an option. rebuilding the table is a last resort. I would like to understand how this happened, and how to prevent it.
The error when trying to do anything to the table, read, edit, drop, etc:
Attempt to fetch logical page (1:27232) in database 23 failed. It belongs to allocation unit 72057594049069056 not to 281474980642816.
the first allocation unit # is sysobjvalues, and the second is g2_pluginparametermap
the table that the error happens on is g2_Item.
CHECKDB returns this error:
Msg 605, Level 12, State 3, Line 1
Attempt to fetch logical page (1:27232) in database 22 failed. It belongs to allocation unit 72057594049069056 not to 281474980642816.
Msg 8921, Level 16, State 1, Line 1
Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.
(tempdb is only 14megs, the drive has almost 30 gigs of free space. the db in question is only 300 megs)
dbcc page(db,1,27232,1)
returns nothing
I thought for sure I had manually made a backup quite awhile ago when I knew this table was fine. I restored the backup to a new database and am having the same exact problem.
I found this script some where on internet..i am not sure what it does and how to i solve the problem because my friend has already run the script and i donno how to get back to the original configuration.
/* this script works on a database that is a copy of pubs. I created this database easily with DTS
This only works on SQL Server 7 databases
*/
/* NOTE: This script will truly corrupt a database. It should not be run on ANY real
database. It is only for simulating corruption for training purposes.
*/

go
reconfigure with override
go
update sysindexes set FirstIAM = 1234
where id = OBJECT_ID('roysched')
go

How to sovlve the issue after the corrupt is done...how do i modify the info back to original..
Are there any other process or script that i can simulate to corrupt the databse and solutions pertaining to the same..i would like to experiment and then see how it goes and how quickly i can solve...
Thanks,
Jeff
The ldf file of a db was deleted by mistake. This was done whilst the SQL Server Service was still running. The db was not detached cleanly. I ran sp_detach_db on the db and tried re-attaching but got the error message:
"Database [dbname] cannot be opened because some of the files could not be activated".
Subsequently I have tried creating a new db called the same as the old one. Stopping the MSSQL service, copying over the mdf and re-starting the service. The db still comes up as suspect and the error log shows "Device activation error. The physical file name 'D:LogsETERBK_Log.LDF' may be incorrect". I have tried copying over the new ldf to the correct location but the same message appears.
I am not interested in getting the data back but would like to get back the stored procedures. Can anyone help this is urgernt?
Have a corrupt SQL database that I am unable to repair using any of the repair options with DBCC CHECKDB. Below is the output from the repair_allow_data_loss option.

I had installed a third-party software on my server and that corrupted my Master DB. Over the weekend when we bought SQL server down, we could not bring it back up. I had to re-install SQL server and then restore all my databases from the backup. Is there a better way of doing this???

Hi everybody,
I have a strange problem with one of the jobs created through a maintenace plan. The idea is that every 2 hours a transaction log backup is created and backups older than 2 days should be removed. This worked for several months without a problem, but suddenly today the job reports failed as status.
I looked into jobhistory but all I got is the following message:
sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed.
Strange enough reports the sqllog that the t-log has been backed up succesfully. The files are on disk and I can restore them without a problem.
Any ideas what is going on ???

Hi All,
I am working in a test environment where I need to corrupt a database for test purpose/R&D. After corrupting the database, I ran the DBCC CHECKDB (pubs, repair_fast) and then DBCC CHECKDB (pubs, repair_rebuild) commands. But DBCC is not fixing the corrupt database.
My question is why DBCC is not fixing the corrupted Database? Is that a limitation of DBCC or is there any other way/command or tool to fix the corrupted database other then restoring from the previously backed up file.
The following are the steps that I followed to corrupt the database:
I used the following script (available in the script section of www.swynk.com) to corrupt the pubs database.
sp_configure allow, 1
go
reconfigure with override
go
update sysindexes set FirstIAM = 1234
where id = OBJECT_ID('roysched')
go
sp_configure allow, 0
go
reconfigure with override
go
Then I did a select * from roysched. I got the error:
Server: Msg 5180, Level 22, State 1, Line 1
Could not open FCB for invalid file ID 53764 in database 'pubs'. Table or database may be corrupted.
The pubs database got corrupted. Now, I want to fix this error. So I set the pubs database to single user mode and ran the DBCC command :
DBCC CHECKDB (pubs, repair_fast) that doesn't help so I ran the DBCC CHECKDB (pubs, repair_rebuild) command.
I got big DBCC output. I doesn't seems to fix the pubs database. When I did a select * from roysched again it gave the same corruption error.
I would appreciate any help in this issue.
Thanks

Hi,
I am receiving an Msg 2540 on a database when I perform the DBCCs. It looks like the indexes on this one table got corrupt. I know this because when I perform the DBCCs with the noindex option then I do not get any errors. I tried to drop and recreate the indexes (two indexes - one clustered and one unique) but to no avail. The dbccs continued to produce the error.
If someone has any ideas please respond. This is a prodn problem and so any input would be greatly appreciated.
Thanks again

After implementing a recommendation to perform dbcc checkalloc before nightly backup, I began getting the error below on msdb. Books Online suggests restoring from a known clean backup. We have only been using SQL Server for a few weeks and it seems that all our backups of msdb have the same problem. Is there any way of correcting this problem?

Hello!
I'm intrested in all possible ways to corrupt data or log files in SQL server 2000 except of manualy editing them or cutting the comp's power abruptly.
Thank you.
