Has anyone come across the problem of transactions not being able to write to the transaction log while a 'dump transaction' operation is in progress and therefore causing the transaction to timeout??
Is there any way of eliminating the timeouts/contention??
We are experiencing some problems when running the same package on multiple threads of a C# application concurrently. The package instances seem to share a Dts.Variables collection.
I have created a test application and package to reproduce the issue. The package is very simple. It has two variables - Instance (Int32) and Content (string). The test application runs two concurrent threads that run through 25 iterations running the package. Each thread loads the package, sets the instance, and then runs the package. The package then takes the instance, sticks it in the Content variable and then writes it to a file called "FileX" where X is the Instance. Thread 1 sets the instance from 1 to 25, thread 2 sets it from 26 to 50. The test execution results in about 15% of the files containing the incorrect "instance content". That is, I'll see "42" in the file named "File14", or something along those lines. This tells me that the variables are being overwritten.
I ran another test where I created a copy of the package, so the code is identical, but the VersionGUID is different. Running the thread test application always succeeds. There is no file name/content mismatch. I then ran another test where I manually edit the XML of the package to change the VersionGUID before the package is loaded (by calling LoadFromXml). Again this never fails.
Changing the VersionGUID may work for us, but it is a total hack. Has anyone else experienced this or have any other solutions? Any thoughts on manually updating the VersionGUID to get around this problem? I hate doing this, but we are getting desperate.
Hi - have 150,000,000 row table receiving BULK INSERTS all day - I have also found out my client likes to performan READ opertions simultaniously against this table with of course chronic contention issues.
Need to provide a quick-fix, will index views enable me to abstact the reporting data away from the BULK INSERT table and is there any connection issues between the base table and the Index View?
I have used Extented event to monitor the occurances of TempDB contention on Production server . I found there are several entried logged in in 30 mints .Now I am trying to determin if Tempdb contention on PFS, GAM or SGAM page then I will decide if I need to increase the number of TempDB data files on Production server . Currently , There are 8 TempDB Data files configured on its separate Disks .There are Page_IDs I found in the extented events for Tempdb files -
Page_ID =1 for PFS page Page_ID = 2 for GAM page Page_ID =3 for SGAM page
but I found the Below Page_IDs and I know there is a formula that you can use to identify if page is PFS,GAM or SGAM ? How should I use this formula and what should I look for to determine if page is PFS,GAM or SGAM ? Is there any threshold value for the duration of TempDB contention occured ?
I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.
If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.

It's got me stumped, so any ideas gratefully received.Thx
I have a design a SSIS Package for ETL Process. In my package i have to read the data from the tables and then insert into the another table of same structure.
for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.
if i'm using the 0 for commandtime out then i'm getting the Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
and
Failed to open a fastload rowset for "[dbo].[P@@#$%$%%%]". Check that the object exists in the database.
I am getting this error :Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.

Exception Details: System.Data.OleDb.OleDbException: Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.have anybody idea?!
i have a sequence container in my my sequence container i have a script task for drop the existing tables. This seq. container connected to another seq. container. all these are in for each loop container when i run the package it's work fine for 1st looop but it gives me error for second execution.
Message is like this:
Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
i am getting this error "Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.".
my transations have been done using LINKED SERVER. when i manually call the store procedure from Server 1 it works but when i call it through Service broker it dosen't work and gives me this error.
I have Full database backup upto previous day and transaction logfile of Today transaction. my database has crashed. I have restored previous day's Full backup. I have faced difficulty to restore today's transaction from today's transaction log. What are the steps to restore full database back and one day's transaction log file. Note: there is no differential database backup and transaction backup.
I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
I created a Calculated measure in cube something like this : ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]). To get only spend transactions. Now, I want to slice this measure with same hierarchy to find the amount distribution across different transaction types under spend transaction. But this query behaving like the measure doesn't have relation with measure.
you can think this as below query: WITH MEMBER SPEND AS ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]) SELECT NON EMPTY {SPEND} ON 0 ,NON EMPTY ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent]) ON 1 FROM [CUBE]
How do I make use of begin transaction and commit transaction in SSIS.
As am not able to commit changes due to certain update commands I want to explicitly write begin and commit statements. but when i make use of begin and commit in OLEDB commnad stage it throws an error as follows:
Hresult:0x80004005
descriptionyntax error or access violation.
its definately not an syntax error as i executed it in sql server. also when i use it in execute sql task out side the dataflow container it doesnt throw any error but still this task doesnt serve my purpose of saving/ commiting update chanages in the database.
I am having some problem with SSIS transaction. Eventhought I tried to imitate the concept that Jamie presented at http://www.sqlservercentral.com/columnists/jthomson/transactionsinsqlserver2005integrationservices.asp

I am executing a stored procedure something like this
Create Procedure TEST @test1 @test2 AS BeGIN TRANSACTION ONE SELECT... UPDATE.. .... ....
.... TRUNCATE etc and lot of Select,update and delete statements like this ..... COMMIT TRANSACTION ONE
The Block of code which I have b/w BEGIN TRANSACTION AND COMMIT TRANSACTION ..Will it be rolled back if it encounters any errors in the SELECT,UPPDATE,DELETE ..statements which I have with the transaction one. IF not How do I roll back if it encounters any erros b/w the BEGIN TRANSACTION and END TRANSACTION.
---------------------------------------------- dim conn, connectionstring
connectionstring= "Provider=SQLOLEDB.1; Data Source = blahblah; Initial Catalog = abc; User Id = osss; Password=xxx"
set conn = server.CreateObject("adodb.connection") conn.open connectionstring
----------------------------------------------
It's just basically to set up the connection to the SQL server, it works on my other pages, but on a few pages, the last line (conn.open connectionstring) triggers this error:
"Microsoft OLE DB Provider for SQL Server error '8004d00a'
New transaction cannot enlist in the specified transaction coordinator. "
I've never encountered this error before and I couldn't think of any solution... please help!!!
I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)
For instance, run these statements to set up a test: --DROP TABLE testTable1 --DROP TABLE testTable2 CREATE TABLE testTable1 (f1 varchar(1)) CREATE TABLE testTable2 (f1 varchar(1)) CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1) insert into testTable1(f1) values ('a')
So table testTable1 has a unique index on it..
Now try to run these statements:
--DELETE FROM testTable2 BEGIN TRANSACTION insert into testTable1(f1) values ('a') insert into testTable2(f1) values ('a') COMMIT TRANSACTION
SELECT * FROM testTable2
..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?
Hi,On My local SQL server I have added a linked server to another SQLserver (remoteserver) in another Windows NT Domain.When I run this codeselect count(*) from remoteserver.mosaics.dbo.LocationThis works fine.However when I usebegin transactionselect count(*) from remoteserver.mosaics.dbo.LocationIt errors out saying thatThe operation could not be performed because the OLE DB provider'SQLOLEDB' was unable to begin a distributed transaction.New transaction cannot enlist in the specified transactioncoordinator. ]OLE DB error trace [OLE/DB Provider 'SQLOLEDB'ITransactionJoin::JoinTransaction returned 0x8004d00a].My question is even though I am just reading data from theremoteserver, why does the local transaction get promoted to adistributed transaction.Any help will be grately appreciated.TIA...Rohit

Hello, I've a problem with a software developed in C# with the framework 2.0. This is the error I receive : The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" returned message "No transaction is active.". If I try directly to restart the process, it works fine. Is there someone who can help me ? This is the process 1. In C# --> Call of a Query : select from the linked server (db in sql 2005) and insert into a table SQL 2005 2. In the C# --> using (TransactionScope scope = new TransactionScope()) and insert in a table in SQL 2005 which is link server Thank in advance.
I found the following link which seems to be the problem we're experiencinghttp://support.microsoft.com/kb/937517
The link includes a workaround which is the following: "To prevent the SQLNCLI provider from sending an attention signal to the server, use the SQLNCLI provider to consume fully any rowsets that the OLE DB consumer creates. "
How do I use the SQLNCLI provider to fully consume any rowsets?
Hello everyone,This is more of an architectural question about SQL Server. Cansomeone please explain why when I perform a query such as the onebelow that updates a table using begin and end transaction I am unableto programmatically truncate the transaction log. The only way I havefound to truncate the transaction log is to stop and start the SQLServer Service. Does this transaction use the tempdb? Is that why Iam unable to truncate the transaction log? Is there a better way todo this?Begin trans T1Update sometableSet random_row = 'blah'End trans T1Thanks!
I have a large database in full recovery model (9.0.3152).
I have s stored procedure, that generates a HUGE transaction log, i have optimized the stored proc as much as i can, i have also broken it up into smaller transactions that i commit more frequently and do transaction log backups more frequently.
However i cannot make a significant dent into the transaction log size.
Is there anyway / syntax to ensure that a transaction or statement is not logged to the transaction log ?
I will never want to have this transaction or commands present if i do a restore.
I have a stored procedure 'ChangeUser' in which there is a call to another stored procedure 'LogChange'. The transaction is started in 'ChangeUser'. and the last statement in the transaction is 'EXEC LogChange @p1, @p2'. My questions is if it would be correct to check in 'LogChange' the following about this transaction: 'IF @@trancount >0 BEGIN Rollback tran' END Else BEGIN Commit END. Any help on this would be appreciated.
Hi have have two linked SQL Servers and I am trying to get things workingsmootly/quickly.Should I be using 'BEGIN TRANSACTION' or 'BEGIN DISTRIBUTED TRANSACTION' ?Basicly, these SPs update a local table and a remote table in the sametransaction.

Need to clear up some needed space. What is the trancsent sql command to clear out your transaction log. Will this prevent any disaster recovery efforts to restore altered/dropped tables?
I know this is a novice question but I have a database that is 12 GB and the transaction log is 6GB and I am concerned about disk space. Is this a normal size for a transaction log and how do I maintain the log so that it stays what I may deem reasonable. I know that the database grows automatically but can I purge the log or have the log purge itself and start over automatically?
