SQL 2012 :: Failed To Lock Variable RunID For Access With Error

Sep 17, 2015

I have created some packages in visual studio and run the packages from there and they all run fine. I have then imported the THEM in SQL Integration services Catalogues and run the packages individually and they all run successfully.When I tried to create the job to run the packages in a scheduled job I get the following error messages: Backup database error: failed to lock variable "RunID" for access with error 0xc001001 "The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the variable collection on a container during execution of the package and the variable is not there.....

Backup database error. The execute method on the task. Backup database returned code 0x80131904 (Login failed for user 'loginname' The execute method must succeed and indicate the result using an "out" parameter.

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

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.

May 22, 2006

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.

From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"

Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)

I "sometimes" get the following error:

OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.

Help would be appreciated!

I have seen other posts on this but, not able to relate the solution to my scenario.

Many a times see the below error in SQL Error log.

Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ]

Is this something to do here?

Note: If I run the below statement I know that the SQL Error log entry will go off, but wanted to know the real significance of this error?

A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List

May 10, 2006

Hi All,



I have seen a few other people have this error.

Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)

The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")

A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.

I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.



The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.

Any ideas?



Cheers,

Crispin

Execute SQL Task: Executing The Query Exec (?) Failed With The Following Error: Syntax Error Or Access Violation. Possible F

Jan 23, 2008

Hi,
I'm having an SSIS package which gives the following error when executed :

Error: 0xC002F210 at Create Linked Server, Execute SQL Task: Executing the query "exec (?)" failed with the following error: "Syntax error or access violation". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.Task failed: Create Linked Server

The package has a single Execute SQL task with the properties listed below :

General Properties
Result Set : None

ConnectionType : OLEDB
Connection : Connected to a Local Database (DB1)
SQLSourceType : Direct Input
SQL Statement : exec(?)
IsQueryStorePro : False
BypassPrepare : False

Parameter Mapping Properties

variableName Direction DataType ParameterName

User::AddLinkSql Input Varchar 0


'AddLinkSql' is a global variable of package scope of type string with the value
Exec sp_AddLinkedServer 'Srv1','','SQLOLEDB.1',@DataSrc='localhost',@catalog ='DB1'

When I try to execute the Query task, it fails with the above error. Also, the above the sql statement cannot be parsed and gives error "The query failed to parse. Syntax or access violation"

I would like to add that the above package was migrated from DTS, where it runs without any error, eventhough
it gives the same parse error message.

I would appreciate if anybody can help me out of this issue by suggeting where the problem is.

Thanks in Advance.

SQL 2012 :: Variable Returning Asterisk Instead Of Error

Aug 27, 2014

This query was run against a database on 2008 SP3 and 2012 SP2

Here is an example of what I ran

Declare @A_number varchar(5)
Select Top 1 Column_Is_an_int = @A_number
From Our_Main_Table
Where A_Database_Name = 'A database with many records in this table and multiple records in the Column_is_an_int some are more than 5 characters'

Select @A_number
Exec My_Stored_Proc @A_Nmuber

The top result for that database had an integer that was 8 characters including the - sign.

When the query ran I would normally expect it to throw the binary data cannot be truncated error. However in this case it returned a * in the variable which then tried to pass it in to the SP which of course threw a fit.

Once I changed the varchar(5) to varchar(50) it worked perfectly.

SQL 2012 :: DB Backup Failed Because Of Error 9002

Aug 12, 2014

SQL server 2012, SP1

DB is in SIMPLE recovery mode (total size 124 GB). Log file Initial size is 650 MB auto growth set for 500 MB.

Below is the error I am facing.

Could not clear 'DIFFERENTIAL' bitmap in database 'DBSAPCAD' because of error 9002. As a result, the differential or bulk-logged bitmap overstates the amount of change that will occur with the next differential or log backup. This discrepancy might slow down later differential or log backup operations and cause the backup sets to be larger than necessary. Typically, the cause of this error is insufficient resources. Investigate the failure and resolve the cause. If the error occurred on a data backup, consider taking a data backup to create a new base for future differential backups.

A nonrecoverable I/O error occurred on file "//SQLDIFF/SAPCAD_DBSAPCAD.bak:" 995(The I/O operation has been aborted because of either a thread exit or an application request.).BACKUP DATABASE is terminating abnormally.

In the weekend we faced an error on the DB backup.Drive K got full because of database log file grown and we have 4 MB free space left. I have no option to increase the drive space nor the log file size.

I am unable to perform, full or differential backup for this db.

SQL 2012 :: Test Connection Failed Because Of Error In Initializing Provider

I am creating my first SSIS package, simple, I read a file, a computation and then write it to an excel.

I am getting the message: "Test connection failed because of an error in initializing provider." The database is NOT remote. My computer is slow though. after about 10 or 15 seconds after clicking the button to test my connection, I get the message and much more. The message asks me if the instance name is correct. I don't know what this would be. This message is on the first task, reading the file (finding the file).

The last sentence of the long message is: "Named pipes provider: Could not open a connection to SQL Server (2).

My question is: Why am I getting this message and what do I need to do to resolve this problem?

SQL 2012 :: Finding Lock Escalation Cause

Jun 17, 2015

While running SQL Server Profiler I reached some Lock:Escalations. When I searched for Statements having same SPID as Lock:Escalation event I realized that one of delete statements causes this. Is there any way to find out why lock escalation in such place occurres?

Statement is like:

delete from BOOK_IN_LIBRARY where libraryId in (,,,,); <-20 elements ids

CREATE TABLE BOOK_IN_LIBRARY(
[libraryId] [bigint] NOT NULL,
[bookId] [bigint] NULL,
[otherData] [bigint]NULL,
[otherData2] [int] NULL,

SQL Server 2012 :: Perform Update But Skip Lock

Mar 7, 2014

I open query analyser and on one tab I update a record in a transaction and hold it.

begin tran
update customers set territory = 'x' where customer = 'A00001'
--rollback tran

In a second tab I attempt to update all records in the table

update customers set carrier = ''

Clear this fails because of the lock placed during the first script and this is fine.

However, is there a way to get the 2nd script to ignore the locked rows and just update as many as it can? The obvious answer seemed to be the READPAST hint like follows…

update customers with (READPAST) set carrier = ''

…but this is still blocked by the original lock. I’ve tried combining it with all sorts of other table hints but all seem to get blocked.

The following does work, ignoring the lock and not returning the data

Select * from customers with (READPAST) where customer = 'A00001'

I’ve tried combining this with the update like so…

update customers
set carrier = ''
from customers with (READPAST)
where customer = 'A00001'

..but this is blocked too.

I’m so desperate I tried moving the update into a cursor and update one row at a time. Nothing worked. I thought I might be able to do something like this

If (Select count(*)
from customers with (READPAST)
where customer = 'A00001') > 0
--then perform update

..but this returns a value of 1 even though the following returns no rows.

Select * from customers with (READPAST) where customer = 'A00001'

After the 3 messages the following error message is shown for every database:

Populating An Access Combo Box With Large Amount Of Data Causes Table Lock In SQL Server

Jul 20, 2005

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

SQL 2012 :: SSMS Object Explorer Lock Timeout When Running Compression Script

Jan 21, 2015

ALTER TABLE [dbo].[TableNameExample] REBUILD PARTITION = ALL
WITH (DATA_COMPRESSION = PAGE)

The table is 110 GB, so will take time to compress. But it is one table in a database with 60 tables. Why would executing this statement, cause lock timeout on Object Explorer in SQL Server Management Studio? Users cannot drill down objects in this database without getting lock timeout.

When I cancel the compression script, users of SSMS can access objects in this database again from the GUI. Why does compressing a specific table affect access to all tables metadata? I cannot find anything on the internet but I am sure this has happened to other people.

SQL Server 2012 :: Find Queries That Lock Tables Or Not Using Primary Key While Running Update

Jul 20, 2015

I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.

If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.

If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.

SQL Security :: ALTER DATABASE Failed Because A Lock Could Not Be Placed On Database

Jul 20, 2015

I have a script that automates some db drop/restore operations and bringing the database to single user mode is part of it: ALTER DATABASE ... SET SINGLE_USER WITH ROLLBACK IMMEDIATE...I want this to executes under a login, that has restricted privileges, so I've created a login and granted it a dbcreator role + ALTER ANY DATABASE privileges.

Problem: When I run the script against a database with an active/sleeping connection:It fails when using the restricted login: "Msg 5061...ALTER DATA BASE failed because a lock could not be placed on database ..."It completes successfully when using a sysadmin login According to stackoverflow.com the solution is to kill the active/sleeping connections to the database, before ALTER-ing it, which works fine, but the question is....

Questions: Why the "ALTER DATABASE..." statement works under the sysadmin login, but not under a dbcreator one?Does this mean the sysadmin login kills the connections to the target database in the background?Is it possible to grant additional privileges to the restricted login, so the "ALTER DATABASE..." statement won't need preventive killing of the connections?

Row Lock Versus Page Lock In SQL 2000.

Apr 7, 2004

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.

Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.

At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.

So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.

Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :

Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction

We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.

How can I resolve this issue? How can I get lock on wanted rows instead of entire page?

Please advice. Thanks a bunch.

ADS System Timed Out Waiting For Lock Error

Feb 6, 2007

I am attempting to modify the ADS sample to work with my own application and am running into a snag. I have a simple sqlce database that has two tables in it. I have everything working up until the point where I try to "Pull" the data. At this point in time this is what happens.

1.) I successfully Drop Table1 from the SQLCE database and then Pull "Table1" from the desktop database

2.) When attempting to Pull Table2. It runs the DoesTableExist Function, identifies that the table does exist and therefore tries to run the "DropTable" routine before Pulling the desktop Table2 data. As soon as the sqlCmd.ExecuteNonQuery of the DropTable routine runs I get the following error....

"The system timed out waiting for a lock. [ Session id = 1,Thread id = 1318094114,Process id = 1318068802,Table name = Table2,Conflict type = x lock (s blocks),Resource = DDL ][Table2]"

Of Note...I converted the sample to VB.NET so it's possible something didn't convert right? My guess is that it probably has something to with my SQLCE Database but I haven't the slightest clue where to go from there. Anyone have any ideas what might be going on?

Thanks,

Mike

Data Access :: Selecting Data Without Making Any Lock

Oct 26, 2015

I have a scenarios where if I execute select * from tbl it should display the all the records without waiting to release any lock.  For example suppose I have one table called tbl and one session is updating one records and not committed yet and in other session if i execute select * from table I can see all the records, for that records it can show me older version. but my select statement should not wait to commit another session and also it should not show the modified data.

Execute SQL Task: Variable Mapping Failed With Complex SQL Script. Please Help!

Jul 23, 2007

Hi all,
I'm working with Execute SQL task. Connection type: OLE DB. With the following settings, the task works fine:

Parameter mapping:



Code Snippet

Variable Name Direction Data type Parameter Name
User::InputFile Input NVARCHAR 0
User::DesiredOutput Input NVARCHAR 1
SQLStatement:



Code Snippet

exec [spu_CreateOutput] ?, ?

However, I want to put in some conditions so I modified the task as:

Parameter mapping:



Code Snippet

Variable Name Direction Data type Parameter Name
User::OutputFile Input NVARCHAR 0
User::InputFile Input NVARCHAR 1
User::DesiredOutput Input NVARCHAR 2

SQLStatement:



Code Snippet

if(? <> 'NotUsed')
Begin
exec [spu_CreateOutput] ?, ?
End

But the modification doesn't work. The following message was thrown:

Error: 0xC002F210 at CREATE OUTPUT, Execute SQL Task: Executing the query "if(? <> 'NotUsed')
Begin
exec [spu_CreateOutput] ?, ?
End
" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: CREATE OUTPUT

Can anyone tell me what I have been wrong with it? It seems that parameter mapping can only apply for a single select statement/function/procedure call :-?

Thank you,
GiaHi
