Is it possible to query linked servers without the Distributed Transaction Coordinator service enabled or allowing network access?
Is that ONLY for transactions? What if I just wanted to read the data and nothing else?
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?
SQL Server version 7.0 (Service Pack 1)
When trying to start the Distributed Transaction Coordinator through Enterprise Manager, the following error is returned:

Any ideas?
Hi all,
I am trying to updated data on a different database on a different server. I am using linked servers for this. I can do select,updated , insert using the linked server in the management console but when i try to update the tables on remote server thru trigger i get this message MSDTC on server 'myserver' is unavailable. i checked the distributed transaction co-ordinator service in services.msc and its show that its running. Then i checked the logs in sql server 2005 and i see the following message
"The Microsoft Distributed Transaction Coordinator (MS DTC) service could not be contacted. If you would like distributed transaction functionality, please start this service."
i also see the the red stop icon on the distributed transaction co ordinator in under management in sql server 2005. i have enabled remote proc trans using sp_configure
Pls advise
Distributed transactions were happily running between our SQL servers and then we installed Windows 2003 Server SP2 and all of a sudden we got this nice error message when attempting a remote data update via linked servers. I couldn't even run "BEGIN DISTRIBUTED TRANSACTION" without getting the error message. The full error message is:
"Enlist operation failed: 0x8004d00e(XACT_E_NOTRANSACTION). SQL Server could not register with Microsoft Distributed Transaction Coordinator (MSDTC) as a resource manager for this transaction. The transaction may have been stopped by the client or the resource manager."
Apparently, SP2 disables network DTC access (how nice, I feel more secure knowing that my data can't be updated remotely anymore).
Solution:
From Control Panel | Add or Remove Programs | Add Remove Windows Components
Select "Application Server" and click the "Details" button
Check "Enable network DTC access" and click OK for however many prompts it takes to apply the changes.
****NOTE**** this change WILL SHUT DOWN SQL SERVER so plan accordingly (this would have been handy to know in advance since I ran it in the middle of the workday and everyone got disconnected).
Hope this helps!

I have 4 servers, 2 each for application (Dev & Prod)
DEV 1 & DEV 2 are standalone serversÂ
Prod 1 & Prod 2 are Windows Clustered Servers.
From one application to other we do Distributed transactions. Dev 1 - Dev 2 or Dev 2 - Dev 1 can start DTC and working fine,but issue comes when Prod 1 - Prod 2 or Prod 2 - Prod 1. I get error message OLE DB provider "SQLNCLI" for linked server "xyz" returned message "No transaction is active.".

I have two servers linked with sp_addlinkedserver. Now I open a connection to server1 and try some insert queries in server2. It throws up an exception saying nested transaction could not be opened. Please note that I have only one transaction which builds all sql queries and inserts. The exception message aso says,
" The nested transaction was initiated because XACT_ABORT was set to off"
Where am I going wrong? Please help.
Three weeks ago we began a project that involved importing data from an AIX DB2 6 environment via a linked server configuration. Following the data import a second query was executed against the db2 environment using data that resides in the new table within SQL 7 in the join statement (a very basic example is provided below) This was all accomplished in sequence via a package.
SELECT F_NAME, L_NAME, PASSWD
FROM SQL7.LOCALSRV.dbo.NEWUSERTBL as new, DB2.SYSIBM.MASTERTBL.OLDUESRTBL as old
WHERE new.USER_ID = old.USER_ID
Originally we had no problems and while the execute time was not exactly speedy it was tolerable as we would revisit optimization after we established if what we were trying to accomplish was feasible. At the outset the first data import to build the local table was immeadeate and then the distributed query to retirieve more info to build another local table against the DB2 server took aproxiamtly 1 minute per user row returned. Currently we are looking at still having an immeadeate data import (a matter of seconds to build the first table)but now we are looking at more than 1 hour returned for 1 correesponding row of data off of DB2. We are utilizing the the IBM DB2 ODBC DRIVER.
Any input or suggestions as to what could be causing this or perhaps a more efficeint way to code the statement would be much appreciated. Thanks in advance.

I am working on a linked server where a few of the queries use almost exclusively remote tables from 1 other server. I have read somewhere that there are options to specify where a query is performed but can't find it anywhere. Could someone tell me the command and how to use it or point me to something to read about it.

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.
Please help me it's very urgent.
I am trying to write some admin only procedures which will collect information to one of my development server from other production and development servers.
I have created linked servers to access these other servers on the development server. This development server is SQL Server 2000 EE. Other servers which I want to access are 2000 and 2005 (vaious editions)
E.g I have another development server called PRODTEST which is SQL Server 2005 and on the development server I have created a linked server pointing to PRODTEST called TESTLINKSRV. I want to access new object catalog view (as I do not want to use sysobjects)
When I run the following query
SELECT * FROM [TESTLINKSRV].[DBNAME].[sys].[objects]
I get following error,
OLE DB error trace [Non-interface error: OLE DB provider does not contain the table: ProviderName=' TESTLINKSRV ', TableName='" DBNAME "."sys"."objects"'].
Msg 7314, Level 16, State 1, Line 1
OLE DB provider ' TESTLINKSRV ' does not contain table '"DBNAME"."sys"."objects"'. The table either does not exist or the current user does not have permissions on that table.
So I try this query
SELECT * FROM [TESTLINKSRV].[DBNAME].[sys.objects]
and I get following error
Msg 208, Level 16, State 1, Line 1
Invalid object name TESTLINKSRV.DBNAME.sys.objects'.
So bottom line is how do I access catalog views on a 2005 server from a 2000 server using linked server?
I hope someone understands what I am trying to achieve. Please let me know what is it that I am doing wrong.
Thank you

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.
Thanks in advance.
For example I have 15 records in which accountID is a PK. AccountID 1,2,3,4,5 is linked on server1. I want to find out records that are not linked. So its record 6 - 15. Can someone show the stored procs for this scenario? Or the query statement to do this... Im new to linked servers. Thanks alot.

I receive the following error message when I run a distributed query against a loopback linked server in SQL Server 2005:
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
To resolve this problem, I was told that running a distributed query against a loopback linked server is not supported in SQL Server 2005. And I am suggested to use a remote server definition (sp_addserver) instead of a linked server definition to resolve this problem. (Although this is only a temporary resolution, which will deprecate in Katmai)
However, I run into another problem when I use the remote server definition. I receive the following error message:

Greetings,I have 3 servers all running SQL Server 2000 - 8.00.818. Lets callthem parent, child1, and child 2.On parent, I create a view called item as follows:CREATE view Item asselect * from child1.dbchild1.dbo.Item union allselect * from child2.DBChild2.dbo.ItemOn child1 and child2, I have a table "item" with a column named "id"datatype uniqueidentifier (and many other columns). There is anon-clustered index created over column "id".When I connect to the parent server and select from the viewSelect id, col1, col2, …. From item where id =‘280A33E0-5B61-4194-B242-0E184C46BB59'The query is distributed to the children "correctly" (meaning itexecutes entirely (including the where clause) on the children serverand one row is returned to the parent).However, when I select based on a list of idsSelect id, col1, col2, …. From item where id in(‘280A33E0-5B61-4194-B242-0E184C46BB59',‘376FA839-B48A-4599-BC67-25C6820FE105')the plan shows that the entire contents of both children item tables(millions of rows each) are pulled from the children to the parent,and THEN the where criteria is applied.Oddly enough, if I put the list of id's I want into a temp tableselect * from #bv1id------------------------------------280A33E0-5B61-4194-B242-0E184C46BB59376FA839-B48A-4599-BC67-25C6820FE105and thenSelect id, col1, col2, …. From item where id in (select * from #bv1)the query executes with the where criteria applied on the childrendatabases saving millions of rows being copied back to the parentserver.So, I have a hack that works (using the temp table) for this case, butI really don't understand the root cause. After reading online books,in a way I am confused why ANY of the processing is done on thechildren servers. I quote:================================================Remote Query ExecutionSQL Server attempts to delegate as much of the evaluation of adistributed query to the SQL Command Provider as possible. An SQLquery that accesses only the remote tables stored in the provider'sdata source is extracted from the original distributed query andexecuted against the provider. This reduces the number of rowsreturned from the provider and allows the provider to use its indexesin evaluating the query.Considerations that affect how much of the original distributed querygets delegated to the SQL Command Provider include:•The dialect level supported by the SQL Command ProviderSQL Server delegates operations only if they are supported by thespecific dialect level. The dialect levels from highest to lowest are:SQL Server, SQL-92 Entry level, ODBC core, and Jet. The higher thedialect level, the more operations SQL Server can delegate to theprovider.Note The SQL Server dialect level is used when the providercorresponds to a SQL Server linked server.Each dialect level is a superset of the lower levels. Therefore, if anoperation is delegated to a particular level, then Queries involvingthe following are never delegated to a provider and are always it isalso delegated to all higher levels.evaluated locally:•bit•uniqueidentifier================================================This suggests to me that any query having where criteria applied to adatatype uniqueidentifier will have the where criteria applied AFTERdata is returned from the linked server.Any ideas on the root problem, and a better solution to get the queryand all the where criteria applied on the remoted linked server?Thanks,Bernie

Can someone please shed some light on what seems to me to be a common requirement.
If I create an alias or linked server to Server1 - say Alias1 - on Server1 and then use that name in a query on Server1, a remote/distributed query is always used (even though we are running on the local server and that overhead is completely unnecessary).
Is SQL Server really not capable of deciding that
select * from Alias1.db1.dbo.table1
and
select * from Server1.db1.dbo.table1
should be optimized and executed exactly the same when Alias1 is Server1, but that it is a distributed query ONLY when Alias1 is really referring to a remote server? I realize that the four part name is not necessary when I am referring to objects on the current server, but I am trying to write code that is server instance independent.
It just seems that if that is not possible, then the only way to create system independent stored procs that can run in dev, staging, and production environments and work with multiple databases on multiple servers is to create all sorts of scripts to regenerate all the procs whenever you move a database between servers?
If SQL Server is even close to the enterprise big iron server that MS now claims it is, it surely needs to support running in dev, staging, and production environments and work with multiple databases on multiple servers?!
I'm really looking for someone to tell me I'm missing something simple, and of course you can do this - but complex workarounds are invited too :-)
This is not something I am investigating as an academic exercise, I am already doing this, but I have to figure out how to do it better because with all these unnecessary distributed queries, performance is horrible.
Thanks
