DTC Select Works - Insert Update Fails Cannot Begin Distributed Transaction
Mar 31, 2015
We have a rather large environment and have just a couple of boxes out there that we are getting cannot begin distributed transaction on inserts and updates but works fine on selects. Inserts and updates work fine outside the begin tran / commit so it's definitely DTC
We have checked the configuration on and the source box is set to No authentication required same for destination.
We have: Verified credentials running the service, changed them, same problem. Uninstalled and re-installed MSDTC per Microsoft instructions.
Have run all the tools for checking DTC DTCPing etc and followed those procedures which typically in the past has resolved any DTC issues. Other than swapping out the offending pc for a new one we are at a loss.

I have 3 development SQL Servers A, B & C, all running SQL 2000 sp3 and Windows 2003. Servers B & C have a linked server pointing to A, and A has one pointing to B & C. The linkedservers all have RPC , RPC out enabled. I have a stored procedure called test on server A.
Create Proc test
as
Select Top 5 first_name, last_name from people
GO
--code ran on Servers B & C:
create table #tmptbl (nm varchar(100), nm2 varchar(100))
insert into #tmptbl
Exec ServerA.db1.dbo.test
When the Insert....Exec code above is ran from server B it works fine, however when I run it from Server C, I get error 7391
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a]
But regular linked server calls (directly to tables) and openquery calls work fine from either server...
Eg
insert into #tmp
Select top 5 first_name, last_name from ServerA.db1.dbo.people
--and this works also
insert into #tmp
Select * from openquery(ServerA, 'Exec db1.dbo.test')
Both servers (B & C) appear to be configured the same, and
I have reconfigured MSDTC on all three boxes through control panel and component manager, have tried using SET xact_abort, SET implicit_transactions, registry hacks (TurnoffRPCsecurity), basically everything listed on Microsoft, and everything I've been able to find in these groups.
If anyone has any ideas, I'd like to hear them.
Tim.

I have this code
DECLARE @tempTableName VarChar(50)SET @tempTableName = NEWID()
CREATE TABLE #@tempTableName( State Char(2), Billed Money, AslCode VarChar(10))INSERT INTO #@tempTableName EXEC GetRecords '2/1/2008'
which gives me this error when I run
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a].
GetRecords does a select * from a linked server's table. Which is working fine but if I try to do an insert (into temp table) then I get the error.
Any help?

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. I cant have one table updated and not the other. Please dontsay replicate the tables either as at this time, this is is not an option.I have for example a number of stored procedures that are based around thefollowing:where ACSMSM is a remote (linked) SQL Server.procedure [psm].ams_Update_VFE@strResult varchar(8) = 'Failure' output,@strErrorDesc varchar(512) = 'SP Not Executed' output,@strVFEID varchar(16),@strDescription varchar(64),@strVFEVirtualRoot varchar(255),@strVFEPhysicalRoot varchar(255),@strAuditPath varchar(255),@strDefaultBranding varchar(16),@strIPAddress varchar(23)asdeclare @strStep varchar(32)declare @trancount intSet XACT_ABORT ONset @trancount = @@trancountset @strStep = 'Start of Stored Proc'if (@trancount = 0)BEGIN TRANSACTION mytranelsesave tran mytran/* start insert sp code here */set @strStep = 'Write VFE to MSM'updateACSMSM.msmprim.msm.VFECONFIGsetDESCRIPTION = @strDescription,VFEVIRTUALROOT = @strVFEVirtualRoot,VFEPHYSICALROOT = @strVFEPhysicalRoot,AUDITPATH = @strAuditPath,DEFAULTBRANDING = @strDefaultBranding,IPADDRESS = @strIPAddresswhereVFEID = @strVFEID;set @strStep = 'Write VFE to PSM'updateACSPSM.psmprim.psm.VFECONFIGsetDESCRIPTION = @strDescription,VFEVIRTUALROOT = @strVFEVirtualRoot,VFEPHYSICALROOT = @strVFEPhysicalRoot,AUDITPATH = @strAuditPath,DEFAULTBRANDING = @strDefaultBranding,IPADDRESS = @strIPAddresswhereVFEID = @strVFEID/* end insert sp code here */if (@@error <> 0)beginrollback tran mytranset @strResult = 'Failure'set @strErrorDesc = 'Fail @ Step :' + @strStep + ' Error : ' + @@Errorreturn -1969endelsebeginset @strResult = 'Success'set @strErrorDesc = ''end-- commit tran if we started itif (@trancount = 0)commit tranreturn 0

I am receiving the following error when I run a stored procedure:Server: Msg 7391, Level 16, State 1, Procedure spXXXXThe SP inserts data into a local (sql 2000) table from a remote sql2000 database. The SP works fine until I add a trigger to thedestination. The contents of the trigger do not appear to matter, as Ihave tried removing everything but one line, which is just a declarestatement. Updating the table with the trigger (even the full trigger)in place does not cause an error. Running the SP without the triggeron the table does not cause the error.I have the exact same setup on another server. Both the SP and thetrigger are IDENTICAL. This setup works on one server, but not theother. The only difference I can see is that the non-working server isWindows 2000 Server, while the working server is Windows 2003 Server.Any idea what's going on here?Thanks in advance.Eric

SQL2000 / W2K
I'm having issues with a query to a view that references a view on a linked server, that in turn references a view on a third server.
Query to view on Server A --> View on Server B --> View on Server C
I can query from A to B using the linked server.
I can query from B to C.
I can query from A to C.
All servers at the same location on the same domain.
I cannot query a view on A, that references a view on B, where the view on B references a view/table on C
Each linked server configuration uses "Be made using this security context", with the user specified being 'sa'. I was hoping to get security out of the equation for debug purposes, hence the sa use.
I have tried from Query Analyzer using both windows and sql auth.
MSDTC is running on all servers as local system.
The full error returned is:
Server: Msg 7391, Level 16, State 1, Line 1
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a].
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
Thanks for any support,

Dear all,
I have been attempting to set up a linked server in SQL Server 2000 to point to an Oracle database (a very old Oracle database, v7!).
The linked server set up works fine. Then I created a database on the same SQL Server. Within that database I created a view which reads information from a view in the Oracle database (linked server). When I attempted to create this view in Enterprise Manager, I get the following error:
"The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction."
And so I created the view in Query Analyzer. This worked perfectly, no errors, and I can now go into Enterprise Manager and call up the view, which happily goes off to the view in the Oracle linked server and pulls back the info. BUT, when I attempt to do the same thing through an application on a different machine (using OLE Db, and a UDL to connect) the same error as above appears.
Does anyone know what this error means, and where I went wrong? Any help greatly appreciated. My view onto the linked server looks like this:
"CREATE VIEW dbo.NLPG_VIEW
AS
SELECT * from openquery(sadaslink, 'select * from NLPG_VIEW')"
Many thanks in advance for your wisdom!
P.S I wondered whether I need to check if the distributed transaction co-ordinator is running but don't know how.
Thanks,

Hello!I have an Oracle linked server connected through MSDAORA. Linked serverqueries work perfectly - the "openquery" ones as well as the4-part-named ones.The problem I have is with embedding the queries within SQL Servertriggers.Trigger:CREATE TRIGGER tgTest ON [dbo].[test]FOR INSERT, UPDATE, DELETEASselect * from openquery(LS, 'select * from ORACLE_TEST')executing "delete from test" in SQL Query Analyzer raises this error:Server: Msg 7391, Level 16, State 1, Procedure tgTest, Line 5The operation could not be performed because the OLE DB provider'MSDAORA' was unable to begin a distributed transaction.OLE DB error trace [OLE/DB Provider 'MSDAORA'ITransactionJoin::JoinTransaction returned 0x8004d01b].I've tried almost every solution I found online, but nothing helped:(This looked promissing: http://tinyurl.com/nk2wd , but it didn't get meany futher.Maybe someone can get me through the troubleshoot mentioned in thatlink:- check if DTC running properlyHow do I check that? If I open the "Support services" in EnterpriseManager and right-click the "Distributed Transaction Coordinatior" Ican stop the service, what indicates the service is running, but isthere anything else I should check? I have 0 items in the right windowpane of the DTC item, is it OK?- registry setting as discussed earlierThe following Registry Keys should be entered:[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCMTxOCI ]"OracleXaLib"="oraclient8.dll""OracleSqlLib"="orasql8.dll""OracleOciLib"="oci.dll"My entries are:"OracleOciLib"="ociw32.dll""OracleSqlLib"="SQLLib18.dll""OracleXaLib"="xa73.dll"Are they OK?- check if Mtxoci.dll is loadedThere is a Mtxoci.dll in my system32 dir, but how do I tell if it'sloaded?

I have a database containing my own tables and data and I wanted tobe able to query this against an accountancy program which has an ODBCdriver. This was never a problem with MS Access and Jet but I hit Jet'slimitations and have moved to SQL.Creating my own SQL database was no problem, but I was unsure of thebest way to be able to be able to have my SQL tables and my accountancysoftware tables appearing in the same Access front end.I created a linked server to the accountancy program. This wassuccessful in that I could see all the tables below the linked server inenterprise manager.My problem occurs when I try to bring the data from these tablesinto my SQL database.I create a new view in my database:-SELECT *FROM OPENQUERY(SAGE_SERVER, 'SELECT * FROM STOCK')(My linked server is called 'SAGE_SERVER' and I am trying to retrieveall columns from the STOCK table.)I then try to save this view and get the following errors.ODBC Error: [Microsoft][ODBC SQL Server Driver][SQL Server]The operationcould not be performed because the OLE DB provider 'MSDASQL' was unableto begin a distributed transaction.[Microsoft][ODBC SQL Server Driver][SQL Server]OLE DB Error Trace[OLE/DBProvider 'MSDASQL' ITransactionJoi JoinTransaction returned 0x8004d00a].Thanks in advance,Marcus Thornton.

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.

Hi Folks,
I have been trying to setup distributed views. On two machines I was successful. These machines do not have any domain configured. I was running SQL 2000 Enterprise on both machines with Win2K.
The steps I followed were:
1) Add linked servers
EXEC master.dbo.sp_addlinkedserver @server = 'FED2', @srvproduct = 'SQLServer OLEDB Provider',@provider='SQLOLEDB', @datasrc='WEBSERVER1', @catalog='Federated_Bridge'
2) Add linked servers login
EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname='FED2',@useself='False',@locallogin=NULL,@rmtuser='sa',@rmtpassword='mysapwd'
3) Create table
create table Entity_2(id int not null ,EntityID int not null)
go
4) Add Table constraints
ALTER TABLE [dbo].Entity_2 ADD
CONSTRAINT [CK_11] CHECK ([EntityID] <= 10),
CONSTRAINT [PK_Entity_2] PRIMARY KEY CLUSTERED (id,EntityID )
GO
5) Set Xact Abort on
SET XACT_ABORT ON
GO
..The above steps were repeated on two machines. Step 4 was changed so the check constraint did not overlap.
The steps worked. But now I am trying to do the same thing on two different machines. Both are running Win2K and SQL 2000. The only difference that I can see in the setup is that these new machines are setup under a single domain - ie there is a domain controller - whereas in the first case there is no domain controller.
The error message I get is:
Server: Msg 7391, Level 16, State 1, Line 1
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a].

We have a test db, a staging db and a live db. I have a stored procedure that runs fine on test and staging, but throws the following error on live.
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
The stored procedure uses linked servers and a transaction.
We're using the following transaction code in the stored procedure
BEGIN
BEGIN TRANSACTION
BEGIN TRY
---
procedure stuff here
---
COMMIT TRANSACTION
END TRY
BEGIN CATCH
DECLARE @ErrorSeverity INT, @ErrorNumber INT, @ErrorMessage NVARCHAR(4000), @ErrorState INT
SET @ErrorSeverity = ERROR_SEVERITY()
SET @ErrorNumber = ERROR_NUMBER()
SET @ErrorMessage = ERROR_MESSAGE()
SET @ErrorState = ERROR_STATE()
IF @ErrorState = 0
SET @ErrorState = 1
RAISERROR ('ERROR OCCURED:%d', @ErrorSeverity, @ErrorState, @ErrorNumber)
IF XACT_STATE() < 0
ROLLBACK TRANSACTION
END CATCH
END
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?

I have an SQL statement that, when run through SQL Server management studio works fine. However, when I run it on my ASP page, it doesn’t update the data! I have tried both as a stored procedure and as a simple commandText update statement.
All I do is simly update the value of a column based on another column – nothing particularly complex: update customer set dateChanged = System.DateTime.Now.ToString("dd-MMM-yyyy"), CURRSTAT = 'Active',custType = case WHEN cust_Changing_To IS NOT NULL THEN cust_Changing_To ELSE custType END,cust_Changing_To = NULLFROM customers_v WHERE CURRSTAT = 'Changing'
As you can see, nothing that complex. The line that is causing the problem is the case:
custType = case WHEN cust_Changing_To IS NOT NULL THEN cust_Changing_To ELSE custType END
all it does is if another nullable integer column is not null, sets it to the value of that column, else it retains its existing value.
Like I say, this works in Management studio, but I cannot get it to execute programatticaly from an asp page.
No exceptions are being thrown, it just doesn’t update the data.
Any ideas?
Thanks

This one has me stumped.
I created an updateable partioned view of a very large table. Now I get an error when I attempt to declare a CURSOR that SELECTs from the view, and a FOR UPDATE argument is in the declaration.
There error generated is:
Server: Msg 16957, Level 16, State 4, Line 3
FOR UPDATE cannot be specified on a READ ONLY cursor
Here is the cursor declaration:
declare some_cursor CURSOR
for
select *
from part_view
FOR UPDATE
Any ideas, guys? Thanks in advance for knocking your head against this one.
PS: Since I tested the updateability of the view there are no issues with primary keys, uniqueness, or indexes missing. Also, unfortunately, the dreaded cursor is requried, so set based alternatives are not an option - it's from within Peoplesoft.

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.

I have 2 Gridviews and a DetailsView for each GridView. The first Gridview and DetailsView work fine and I can Insert, Delete and Update the DetailsView just fine. However the second Gridview/DetailsView will only let me Insert but not Delete or Update. When I click on the "Delete" button it just ignores me. If I do an "Edit", when I try to click on the "Update" button it is ignored again and I have to click on "Cancel". I don't get any error messages...
Anyone have an idea what might be wrong?

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.
Anyone know of the reason?

SQL Server 2000, C#, ASP.NET and ADO.NET. I have searched for 3 days trying to figure out why my ADO.NET Transaction executes my stored procedures and runs the .COMMIT() on the server, figured this out by using the SQL Profiler, but the data doesn't show up in the database tables and I recieve no error from SQL or ASP.NET. What gives???? Anyone else ever heard of such a thing. Please help, before I loose my sanity.

Hi
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.
Thanks,

Here is my problem. There is a form where some information has to be filled out while the other does not. Information that is left blank is not inserted into the database so that I don't have millions of empty rows. This works perfectly, keeps the database accurate. When someone goes to update, if they add something new it would need to be inserted, since there is nothing to update. I was going to write a procedure, but that seems like such a waste since this will happen often. Is there an sql command in MS SQL to do this. I tried all of the sql commands from other databases I had used. (I am new to MS SQL). If there isn't one does someone have a procedure that won't create a huge amount of overhead.

Hello,
I seem to have a strange problem in that my code runs fine, but I am trying to INSERT rows into a database, and the rows affected by the INSERT command is alwsy zero, even though no error is thrown. Hence no data gets inserted.
Here is the code:
void recordTick(string pair, DateTime time, decimal sell, decimal buy)
{
SqlConnection thisConnection = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FOREX.mdf;Integrated Security=True;User Instance=True");
insert = "INSERT INTO " + pair + " VALUES(" +
"'" + time.ToString("yyyy-MM-dd HH:mms") + "'," +
"'" + sell.ToString() + "'," +
"'" + buy.ToString() + "'" + ")";
thisConnection.Open();
SqlCommand command = new SqlCommand(insert, thisConnection);
Int32 success = command.ExecuteNonQuery(); // success always = 0!
thisConnection.Close();
}
The database is type .MDF that I created with the Project/Add Component/SQL Database menu. I can inspect it easily in Server Exporer and add data manually with no problem.
Can any one suggest how to get the INSERT to actually add the data?
Any help much appreciated!

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 All,Can any one help by giving me the details/difference in using the Transaction Isolation Levels (read uncommitted, read committed, repeatable read, or serializable)in asp.net. I just want to know in which case we can use these things in begining a transaction, and will it improve the performance. thanks in advance Boo

I need to copy two large tables from one database into another, via the internet. I haven't worked out exactly how yet, but the first issue which has occurred to me is that by the time the first table has been exported (via a SELECT clause?) into a suitable file, the second table (to which it is related) will be out of sync. So, how do I ensure that I end up with a snapshot of the two tables, perfectly in sync with each other? I know that BEGIN/END TRANSACTION makes sure that UPDATES to tables remain in sync, but will it work just for SELECT statements?
