SQL Server Detected A Logical Consistency-based I/

Mar 16, 2008

This local test DB was doing just fine. I fire up SQL Server again, and all of a sudden I can't access it (expend the database in Management Studio). So I detach and try to run this script which was run initially to re-attach it:

USE [master]
GO
CREATE DATABASE [ABS] ON
( FILENAME = N'C:DatabaseABS.mdf' ),
( FILENAME = N'C:DatabaseABS_log.ldf' )
FOR ATTACH
GO
if not exists (select name from master.sys.databases sd where name = N'CMS' and SUSER_SNAME(sd.owner_sid) = SUSER_SNAME() ) EXEC [CMS].dbo.sp_changedbowner @loginame=N'domain estuser', @map=false
GO

and I get this error: SQL Server detected a logical consistency-based I/O error: torn page

Logic Consistency-based I/o Error. Dbcc Checkdb

every few days i'm getting an error in the application log , eventID 824, saying 'SQL Server detected a logical consistency-based i/o error; incorrect checksum. it then recommends completing a full database consistency check (dbcc checkdb).

i have run the dbcc checkdb ('databasename') and it is returning an error msg of:

An internal error occurred in DBCC which prevented further processing
Msg 8921, Level 16, State 1, Line 1

i have oodles of disk space left. any ideas on where to go from here.

SQL Server 2008 :: Error Renaming Logical Filename

Feb 27, 2015

I have a SQL Server 2008 R2 Cluster. I have moved a file to another drive by adding a new file on the drive, doing a shrinkfile with emptyfile. I have removed the old file and when I try to rename the new file to the old files old name, I get an error.

ALTER DATABASE mydb REMOVE FILE myfilename
Msg 5009, Level 16, State 9, Line 1
One or more files listed in the statement could not be found or could not be initialized.

ALTER DATABASE mydb
modify FILE ( NAME = temp_filename
, NEWNAME = myfilename
)
Msg 1828, Level 16, State 3, Line 4

The logical file name "myfilename" is already in use. Choose a different name.

I have completed a failover, thinking the name was being held in cache. I've also renamed to something completely different then tried to rename to the old filename.

'Identity Insert Off' Not Detected, Validation Error

Jul 24, 2007

I am trying to capture the rows that fail during an insert.



The insert is an OLE DB command component.

I have config'd errors to redirect to a flat file.



My problem is this

I need to override the identity, fine if you are using 'fast load' but then you can't capture the redirected rows.

So I am using the regular 'table or view' data access mode, but then I lose the 'keep identity' checkbox.



At this point I add in another OLE DB command "SET IDENTITY_INSERT table OFF" before the actual insert ODB component.



But now it won't validate. I changed the task 'delay validation' property to true, but still it is failing.



It seemingly cannot detect this statement.



So how then can I capture error rows from an insert where I need to switch the identity off?



[This is a one off historic load I am working on]

XML Validation Error Detected On The Target Service. How To Keep And Save The Original Wrong XML Message?

May 9, 2007

Hello,



I have a message that is validated using a schema.


If I send the message that is not compliant with the schema, the message is not enqueued on the target queue but it is send back to the Initiator queue and the message_body contains the description of the Error.



On the Initiator queue I have activated a SP that is I used to end the conversation and log the error.



One of the information that I need to log is the original XML message that causes the validation error so I can check it.


It seems that in the moment I'm on this SP, activated when there is something on the Initiator queue I have no memory of the original message or at least I'm not able to find it.



Any hints/helps??



Thank you very much!

Consistency Error.

Jul 18, 2006

OS & SQL Version:

Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Enterprise Edition on Windows NT 5.0 (Build 2195: Service Pack 4)

It's a working database. It's set up to make a backup every night at 4:15 AM when the load is minimal. When making a backup it should run DBCC CHECKDB without any repair option on. One day i got a notification that backup didn't completed. I checked the errorlogs for the day between last successful backup and the next one failed. Logs are clean.

Here is the result of "DBCC CHECKDB WITH NO_INFOMSGS, ALL_ERRORMSGS":

Table error: Table 'Sessions' (ID 398624463). Missing or invalid key in index 'PK_Sessions' (ID 2) for the row:

Sessions0nonclustered located on PRIMARYLoginTime, BytesIn


REPAIR_FAST does not help. The error isn't cleared.
I have two questions about that issue.
1) How i can dig into that problem? For example i would like to simply look at the row causing problems, but i just don't know how to select rows referencing them by RID. Is it piossible? Actually i don't quite understand what DBCC output means. :(
2) Second question is of course how to correct that problem. :)

Of course i can restore from backup, but i'd like to know if there are other ways? Maybe without loosing all the information which was entered during the day? I can afford loosing several rows from that table, but loosing all info entered is not very good solution. No, i don't need backup strategy involving several DB backup during the day. :) Just don't want to reenter all the info, but it can be done if there are no other ways. :)

Internal Consistency Error

Feb 13, 2007

I have been running log shipping for more than a year now and it has been very successful until just recently. For some reason the SQL Agent jobs that backup the database, ship it across the network to a standby server and restore it are failing. On the source server the backup process is running, the log shipping is running however when it tries to restore it on the destination server it fails with the following error:

SQL Server Help file: Help context: 0 Error Detail Records: Error: -2147217900 (80040E14); Provider Error: 3013 (BC5) Error string: RESTORE DATABASE is terminating abnormally. Error source: Microsoft OLE DB Provider for SQL Server Help file: Help context: 0 Error: -2147217900 (80040E14); Provider Error: 3270 (CC6) Error string: An internal consistency error occurred. Contact Technical Support for assistance. Error source: Microsoft OLE DB Provider for SQL Server Help file: Help context: 0 Error: 0 (0); Provider Error: 3211 (C8B) Error string: 10 percent restored. Error source: Microsoft OLE DB Prov... Process Exit Code 1. The step failed.

If I delete the database on the destination server, re-run the sql agent job that ships the backup job, and re-run the restore job on the destination server the process will succeed without error. This tells me the original backup was fine but something may have been lost during the shipping. Have you ever seen this message before? What does it mean and what should I be looking at to resolve the error?

Thank you.

repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKTABLE (msdb.dbo.sysdtssteplog ).

Is this a DTS package or log file I can just remove, or can I just somehow remove that data from the table? I ask this because all the DTS packages seem to be running (and logging) fine.

Or will this involve restore and replace? What direction should I go from here?

I have not seen any hardware errors on this machine. Yet.

Thanks for any and all help.

Restore Fails With Internal Consistency Error

May 30, 2002

I am trying to restore a production database backup to a new location on a development workstation, and it fails with "An internal consistency error occurred, Contact Support". When I tried this on a more powerful workstation it ran without a hitch. The db is about 1.5GB, and I think the dev workstation may be running out of resources during the restore. I stopped non-essential services and ran from TSQL, and it still fails. Any suggestions other than getting a better workstation?

Thanks,

There are no other corruption issues on the server that I can find. I do not believe there are any current hardware issues, though I am not on site.

What would be the best way to resolve this? Is recreating or defrag/rebuild the index an option, here? Or can I just run a repair on this? Since it's a merge table, I'm a little gun shy, having limited experience with replication.

Thanks.

Insert Trigger Logical Error

Apr 25, 2002

The many that I have spoken to all are clueless on this one. Thanks in advance for the right solution!

The insert trigger I created works fine (well, nearly fine), except that AFTER the first insert operation (ie second, third etc), it always produces the correct results BUT FOR THE PREVIOUS INSERTED ROW. It is as if there is a latency of one row in the temp table INSERTED.

I would greatly appreciate a 'why', and more importantly, a 'how to fix it' for this problem.

If you need to look at the code, a NOTEPAD file is attached.

Much appreciated

--start trigger--
create trigger UpdateAffiliateEarnings
on Orders
for insert, update

Logical Error: Using Expressions &&amp; Package Variables

Jun 24, 2007

Hi,



I have encountered some strange output when testing an SSIS package I've been working on.



Please see this thread for background information: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1590716&SiteID=1. The previous thread was resolved and i have used the tips listed here to create a package with Data Flow Tasks that use expressions to create 'dynamic' queries.



The Data Flow tasks use two package-scope variables to determine the date range that they're operating on - this allows me to script the from / to dates (usually 'last week' range) or, in event of error, 'back date' the job easily without having to update each individual components.



However, something weird is happening - when I have two data flow tasks (DFT) in the same Sequence Container (tasks that are not 'connected' or configured to operate in a flow) only one DFT is picking up the package variable & returning the rows. The other DFT is not returning any rows & seems to be using the default value of the variables.



I have tested this by simply enabling DFT A and disabling DFT B - debugging shows only one DFT executes correctly. The same point is illustrated when I disable DFT A and enable DFT B. However, if I configure DFT A to run after DFT B then both pick up the correct variable values and return the correct row counts!!



I want Data Flow Tasks that pull data from the same remote source to be the same sequence containers so when an error occurs I can get container level transaction support.



Note:

I have thoroughly checked the 'evaluated' expressions in IDE and in Management Studio - this is an SSIS specific quirk (or me!).



Questions:

What's happening here, have I made a conceptual error of how this should work?
On the same variable topic: is there a way to set values for package level variables at execute time .e.g via command line execution / dtsexecui??

Let me know if you need any extra explaination / diagrams etc to understand this, the other (closed) thread I have listed above should provide more context for my problem



Thanks for your support!!

URGENT - Failure On Database Restore - Internal Consistency Error Occurred

Sep 13, 2007

We have received a backup of a database from an external company for a project that we are taking over. We have attempted to restore the database and it fails giving us the error: "Internal consistency error occurred."

We have run the restore verifyonly command with the results: "The backup set is valid." However, I don't have confidence that the verify is telling the complete story.

It appears that the database is restored and the overall restore is failing on the transaction log file.

Any help is appreciated. This is rather urgent.

Error: A Deadlock Was Detected While Trying To Lock Variable X For Read Access. A Lock Could Not Be Acquired After 16 Attempts

Feb 2, 2007

I simply made my script task (or any other task) fail

In my package error handler i have a Exec SQL task - for Stored Proc

SP statement is set in following expression (works fine in design time):

"EXEC [dbo].[us_sp_Insert_STG_FEED_EVENT_LOG] @FEED_ID= " + (DT_WSTR,10) @[User::FEED_ID] + ", @FEED_EVENT_LOG_TYPE_ID = 3, @STARTED_ON = '"+(DT_WSTR,30)@[System::StartTime] +"', @ENDED_ON = NULL, @message = 'Package failed. ErrorCode: "+(DT_WSTR,10)@[System::ErrorCode]+" ErrorMsg: "+@[System::ErrorDescription]+"', @FILES_PROCESSED = '" + @[User::t_ProcessedFiles] + "', @PKG_EXECUTION_ID = '" + @[System::ExecutionInstanceGUID] + "'"

From progress:

Error: The Script returned a failure result.
Task SCR REIL Data failed

OnError - Task SQL Insert Error Msg
Error: A deadlock was detected while trying to lock variable "System::ErrorCode, System::ErrorDescription, System::ExecutionInstanceGUID, System::StartTime, User::FEED_ID, User::t_ProcessedFiles" for read access. A lock could not be acquired after 16 attempts and timed out.

Modify the expression to be valid.

Warning: The Execution method succeeded, but the number of errors raised (4) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

And how did I get 4 errors? - I only set my script task result to failure

Any idea what this error is??
Thanks.

Restore Gives &#39;invalid Logical Page Number&#39; Error

Jun 24, 1999

We tried to restore an empty database from a backup and got:
'Load database encountered an invalid logical page number' error.
This then set the database as 'loading'

Anyone got any ideas?

We aren't exactly sure how big the first database was when the backup was done but if the new database isn't big enough to contain the backed up data, wouldn't we get a more meaningful error?

Logical XOR Operator In T-SQL (SQL Server 2000)

Sep 5, 2006

Hi all....

I was wondering why SQL Server 2000 lacks a logical XOR operator. Do you have a ready to use function that implements it?

How can I program one by myself? I know that A XOR B is equivalent to NOT A * B + A * NOT B. So I tried to create this function :

CREATE FUNCTION XOR

(

-- Add the parameters for the function here

@A BIT,

@B BIT

)

RETURNS BIT

AS

BEGIN

RETURN NOT @A AND @B OR @A + NOT @B

END

But it didn't compile.

How can I pass boolean values as parameters? any other hint?

Thanks

Jaime

SQL Server 2012 :: Error Creating Temp Table Based On IF Logic

Nov 13, 2014

I could deploy across my environment, which is a mix of 2008R2/2012 servers, to give some information on log files. Running into a silly issue right off the bat. The table that DBCC LogInfo() conjures out of magic is different between the two. In 2012 it gained the RecoveryUnitID column. So I'm trying to write some logic to create a temp table based on which version is running. I would like to avoid a global temp table if possible. Here's what I've tried:

sp_executesql creates a table outside of the scope of my session:
DECLARE @PrVers NVARCHAR(128)
, @PrVersNum DECIMAL(10,2)
, @StageTable NVARCHAR(1024) = N''

[code]....

An Error When Instantiating C#-based COM Object In OLE DB Provider Linked To SQL Server Express

Aug 24, 2007

Hi,


I'm working on an OLE DB provider. This provider is supposed to retrieve data from managed application running in background. The data retrieval is handled by C# component communicating with source application via remoting, the data are then exposed via component's COM interface. OLE DB provider itself instantiates the communication component.

Now, the problem: this worked ok in SQL server 2000, but it doesn't seem to work in SQL server express edition. Concretely, the communication component fails to get created (CoCreateInstance ends with 'class not registered') and SQL server logs this:


2007-08-24 14:48:49.42 spid51 Error: 6511, Severity: 16, State: 20.
2007-08-24 14:48:49.42 spid51 Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131022. You may fix the problem and try again later.


I've googled a bit and found out someone else getting this message, and he was told something like 'trying to load CLR in some cases is disabled in newer (>2000) versions of SQL server'.

Now, I have very little knowledge of SQL server, CLR integration etc., so I'm not sure whether this applies to my case as well, but I think so - that problematic COM object is C#-based.

I'd be glad for any hints, ideas how to solve this issue, I just need the OLE DB provider to be able to access that managed application.


Thanks,L.

SQL Server 2005 Large IO And Logical Reads

May 22, 2008

A table in one of my databases is running very slowly. The IO is very high and below is a printout from the SET STATISTICS IO ON command run on a common query used on the table:


(4162 row(s) affected)

Table 'WebProxyLog'. Scan count 3, logical reads 873660, physical reads 3493, read-ahead reads 505939, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

I have a clustered unique index and a nonclustered index on the table. I have ran SQL Profiler and opened the trace in Database Tuning Advisor, DTA displays 0% improvement suggestions. I have a number of statistics on the table and index which are all up to date and fragmentation is less than 1%. I've tried a number of variations on indexes to improve performance but to no avail. There is only one query which runs on the table, and the nonclustered index created on the table did significantly improve performance, however the query still runs at around 23 seconds. The query does bring back a large amount of data however i'm sure there is a way to bring down the IO and logical reads to improve performance.

The table and index scripts are below:




Code Snippet

PS There are 60,078,605 rows in the table

Please help!

Many Thanks
