I want to automate the dbcc checkdb process. I create a temp table called #CheckDbTbl and run the following command:
INSERT INTO #CheckDBTbl dbcc checkdb(MyDbName) with tableresults
I plan to send myself an email if any problems are found.
Does anyone know what Error numbers or Levels or anything else I should look for in the #CheckDBTbl that will tell me a problem exists? Right now I'm only checking for: Level >= 16.
Every night all our DBCC CHECKDB runs on all our databases. The trouble is one of them is very large and the database is inaccessible whilst this runs. DBCC CHECKDB (dbname) WITH physical_only executed by user found 0 errors and repaired 0 errors. Elapsed time: 0 hours 24 minutes 46 seconds
This normally happens fairly shortly after the backup, and normally (but not always) after a series of these entries in the log.SQL Server has encountered 7976 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [D:Program FilesMicrosoft SQL ServerMSSQL11. MSSQLSERVERMSSQ LDATA empdb.mdf] in database [tempdb] (2).Would this cause SQL to automatically run a CheckDB.
I would like to know as to how can I put a Current Date & Time stamp on a FILE NAME automatically which is created by a DTS package.
E.g. I create a file named ABC.TXT daily. How do I get this file to have the current Date stamp so that the file name is ABC121201.TXT without any user intervention.
I have a dataflow task that creates a text file and posts it in a FTP share. In need to rename the file attaching datestamp(current date of package execution) at the end of filename. For ex: My dataflowtask creates a file called 'Samplename.txt'
I need to rename it to : 'Samplename20080225.txt.
I think it can be done using the File task...I see an option to rename the file but not sure of how to configure the task to attach current datestamp.
I see some suggestions online, but complete steps on how to implement the above would be highly appreciated.
I followed the advice of Paul Randal, but Im stumped as I am not able to determin what the corruption issues are. This is SQL 2000 and the database is a Solomon database that was recently upgraded to 6.5. the error I get when running the DBCC checkdb is as follows:
Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:18645) with latch type SH. sysindexes failed. DBCC execution completed. If DBCC printed error messages, contact your system administrator.
DBCC execution completed. If DBCC printed error messages, contact your system administrator. DBCC execution completed. If DBCC printed error messages, contact your system administrator.
Now, the bad news. I am a bit of a novice and have picked this up from someone who left my company. It appears the latch error has been around for some time and only reared up when I instituted a new back up system that runs a dbcc check befor backing up. I don't think I have any clean backups.
In my environment, there is maintenance plan configured on one of the server and while running DBCC checkdb on a database of size around 200GB, log file usage of tempdb is increasing and causing the maintenance job to fail.
What can I do to make the maintenance job run successfully, size of the tempdb database is only 50GB and recovery model is set to simple. It cannot be increased as the mount point on which it is residing is 50GB.
Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB 2) Create table called TEST on primary 3) Insert 40MB of data into test 4) Create another file group called temp in primary size 200MB 5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group. 6) Add another 2 files called DATA2 and DATA3. Both are 200MB. 7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3 8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB, DATA2 = 13MB, DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB DATA1 = 10MB DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over the remaining files in PRIMARY.
I have a few extremely large databases in SQL Server 6.5 sp3 (soon to be 5a - but we won't talk about that!!) NT 4.0 sp4 (about 10 GIG each). I don't have a big window of down-time in order to do any maintenance. Does anyone know of a way to be able to run dbcc checkdb or other dbcc's that I can run to verify the database yet complete within a reasonable amount of time? The last time dbcc checkdb was run, it was started Friday night and still not complete Sunday night. Over a weekend, I may have up to a 24 hour maintenance window.
Any suggestions would be appreciated. Thanks! Toni
Hai , When I ran DBCC CHECK DB of userdatabase, its reporting along with usual messages as Descriptor for system table '8' in database '8' not found in the descriptor hash table. I could'nt understand being familiar error encounterd . Any one will appreciate for the help
I recently took over a SQL server with 300 MB of data. I am relatively new to SQL 6.5 and have been reading that DBCC checkdb and checkalloc should be run at least once per week. Apparently the person before me never ran any of those checks. Is not running the database consistency checks for so long going to present a problem? has anyone run into problems when running those checks? Any advise is greatly appreciated.
I ran "dbcc checkdb(MCMSdb) with no_infomsgs" and I get the following: Server: Msg 8946, Level 16, State 12, Line 2 Table error: Allocation page (1:274992) has invalid PFS_PAGE page header values. Type is 0. Check type, object ID and page ID on the page.
What cane be done to correct this problem? Can this error prevent a user from connecting to the database?
I ran checkdb and found 4 error message on the db.. it seen like same object.. can anyone tell me what it is.. and how can i fix it? thanks !!!!

Does anybody know if the results of DBCC CHECKDB are stored anywhere? If yes, where? Also, if you don't select "attempt to repair minor problems" option when you set up the maintenance plan, will SQL Server let you know about any errors Integrity check encounters? If yes, where the erros can be found?
in the SQL 6.5 documentation it says when running the DBCC CHECKDB, you should make the database read Only or DBO use only. Do you guys know if SQL 6.5 locks rows while this runs? In SQL 7.0/2000 it only locks the schema.
I am using windows nt40 and sql server 6.5 on a DEC ALPHA and accidentlly started a dbcc checkdb. Is it possible to stop the process with out damaging the database?
When running dbcc checkdb from my workstation(nt) I recieve some of the output and then I get "Connection Broken" this is on a 6.5 machine with the service pack 5, what could be causing my ODBC connection to drop during the proccess of running checkdb?
How can I make the dbcc checkdb fail so I can get the errors displayed in the report log? DBCC Checkdb is the step in the integrity job that I run once a month. What I am trying to do is when the dbcc checkdb fails for any reason, I want to get notified so I can correct the problem. I don't want to use repair fast or any other repair parameters that you can select when you run dbcc checkdb function because most of my dbs are 24x7.
I have a job set up that runs the dbcc checkdb and puts the results into a table. Then I run a query against this table to check the results of dbcc checkdb. If there are errors, I get a page that lets me know that there are some problems. When I ran this job on my production server, the job failed stating that there are problems with data integrity. So I copied this db to a dev server and recreated the job just like I have in prod. The job completed successfully withou any errors. Can anybody tell me what to look at to figure out why it failed on the prod server?
Madhur writes "Last week DBCC CHECKDB <database name> took 2 Hrs to complete on a database. Today again i have started but with the following command: dbcc checkdb (<database name>, REPAIR_FAST ).
It is now running for more than 2.5 Hrs now.
Does the execution time increases even when the DB is consistent?
Can we cancel the execution in the middle? What consequences it may have on the db?
I have a db that is about 50Gigs. Last night it went into a suspect mode and I have not been able to get any of my tables to display. I am running the dbcc checkdb. I have been running it for over 7 hrs. Do you have any suggestions as to what I should do or do you have any ideas as to how long this process might take?

My nightly maintenance task runs fine normally. Last night it didn't. When it got to DBCC CHECKDB for an audit database (it gets populated from triggers in other databases; one of the tables has over a million records), the live database server shut down and did not come back up. DBCC CHECKDB completed in 6 seconds with no errors. The next task in the sequence that would have run (but the log has no message of it completing or failing) was DBCC INDEXDEFRAG on that audit table with over a million records.
Even the OFF button on the 64-bit Dell server (SQL2005, Windows Server Enterprise x64 2003 SP1, 16 gig ram) did not work. There wasn't even the blue screen of death. It was just a blue screen. A plug out and plug back in was required.
The only recent configuration change has been that we have had Dell install a piece of disk-level replication software called Double Take.

Hi, Appreciated someone able to provide me some clu on how to perfom DBCC CHECKDB. Is it necessary to set the database to "Read only" before execute DBCC CHECKDB?
I have a database that was handed to me which is getting the following errors:
DBCC CHECKDB ('DBName') returns: Server: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1, index ID 0, page (1:37). Test (m_freeCnt == freeCnt) failed. Values are 680 and 788.

I've looked at the MDF with a hex editor and there's definitely data in there. I have the DB attached and in single user/emergency mode, but DBCC isn't having much luck. Help?
