Trying to locate information on MSDTC. Is this "needed" to run SQL Server? That is, if this part of the installation is deleted, will SQL Server still function? Also, does anyone know if this is a crucial tool needed by Veritas Volume Manager or Windows Disk Manager?
If anyone knows of a link to this information, I'd appreciate it. My searches come up with lots on information on MSDTC, but nothing that answers my specific questions.
When i do a BEGIN TRAN to a SQL server sitting on Windows 2003 Server from a SQL Server Sitting on Windows 2000 Server, the Transaction hangs and if I try o kill it the Transaction is in ROLLBACK State.
I tried setting the Properties for the MSDTC and restarted the Windows 2003 Server but in vain
I keep getting this error on my application server...what does it mean?The description for Event ID ( 0 ) in Source ( ODBC ) cannot be found.The local computer may not have the necessary registry information ormessage DLL files to display messages from a remote computer. Thefollowing information is part of the event: Failed to enlist in DTC:SQL state 37000, native error 8501, error message [Microsoft][ODBC SQLServer Driver][SQL Server]MSDTC on server 'PROSQL' is unavailable..any help would be appreciated...thanks-Jim
I'm using msde. On the little icon in task tray, you have under currentservice, a choice of mssqlserver, and another choice is msdtc. What ismsdtc? And what is sqlserver agent?
The resource msdtc is down. Every time, it works pretty well , after we restart the servers(node1 and node2). But, about half a hour later, the problem is there. We reintalled msdtc. It didn't work out too. msdtc and sql server is on a cluster. Can anyone help me out?
I am running SQl 7.0 (SP4) on Windows XP Professional (SP2). Whenever I try an insert/update type of activity, the System returns the following message :
Server: Msg 8501, Level 16, State 3, Line 2 MSDTC on server 'SERVER' is unavailable.
However, all the required services including MSDTC are running on the System.
I have a class that use a TransactionScope object for make make two operations into a database. The problem is that in a computer works well but in another I receive a error message: "MSDTC is not running in .SQLEXPRESS". I had watched the services in the computer and the "Microsoft Distributed Transaction Coordinator" is running. Does somebody know what is happening? Thankyou and sorry for my English.
I am selectively insert data from serverA databaseX to serverB databaseX. (serverA is linked server on B.)
I could insert parent and child tables. But get error when insert to grand-child tables: Server: Msg 8501, Level 16, State 3, Line1 MSDTC on server B is unavailable.
Don't think I need to turn on MSDTC on B. But I could copy and paste from source A server to target B server. Confusing on some table could insert while others with error....
I have an ugent situation. Due to a failure we had to build a new db server for an application and this was done succuessfully. The application requires DTC and it was not intalled when we install SQL on the server.
How do I install DTC? Did I miss an obscure option during SQL install?
I recently moved & upgraded a database from 7.0 to 2000 that makes use of linked servers. After upgrading, a number of queries started failing with the error below. These linked servers with this problem either had a stopped MSDTC or were behind a firewall. I've read the articles on how to configure MSDTC to work through a firewall, but before I do this I'm wondering why this is even happening. There were no problems when the database was at SQL 7.0. Does anyone know why sql 2000 would need to use MSDTC, but SQL7.0 would not? I don't need to use a distributed transaction, so ideally I'd like to somehow tell SQL not to use MSDTC at all. Any ideas?
Thanks

I have a SSIS package in which there are lot of Sequence Containers. Each sequence container has two Execute Sql tasks which brings 2 values, and if the comparison of the value is true, it runs a data flow task. Comparison is done using Expression.
If any of the sequence container fails the comparison, I wanted whole package to rollback so I had to use Transactions. I set "Required Transaction" on the package and "Supports Transaction" on each Sequence Container and Tasks respectively.
Now that I am trying to run the package, it runs few sequence containers fine and on few it gives this error.
[Execute SQL Task] Error: Executing the query "SELECT ISNULL(MAX(ClaimBillTypeKey), -1) ClaimBillTypeKey FROM dbo.Dim_ClaimBillType" failed with the following error: "Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Also, this is not consistent, one time one Seq. Cont will fail and next time it will run fine but something else will fail. What is going on????
I have set up two server and also created linked server between server1 to server2
I could select from there just fine but when i try to run tirgger on table server1 which updates in server2 it gives me error following: OLE DB provider "SQLNCLI" for linked server "Server2" return message "No Transaction is active" MSG 7391, level 16, state 2, Procedure servertrigger, line 34 the operation could not be performed because OLE DB provider "SQLNCLI" for linked sever "SErver2" was unbale to begin a distributed transaction.
I have configured on both server exactly same: with all the option: MSDTC > Security Configuration: Network DTC Access > TRUE Allow Remote Clients > TRUE Allow Remote Administration > TRUE Allow Inbound > TRUE Allow Outbound > TRUE Mutual Authentication Required > TRUE Enable Transaction Internet Protocol (TIP) Transactions > TRUE Enable XA Transactions > TRUE Account: NT AuthorityNetworkService on both server..
On server2 i tried remote proc trans to on and off but it did not help.
INSERT TABLE1 -- ran at SERVER1 EXEC [SERVER2].DB2.dbo.spInformation @VR_STARTSHIFT = '10/10/2006 06:00:00', @VR_INCDATE = '10/10/2006 14:00:00', @VR_STATION_ID = 221
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].
Server1 has a linked server to Server2 (this linked server is working because i can run the SP without the insert). The Server1 is under WIN2K Server and Sever2 is under WIN2003 The MSDTC is installed and is running in both servers.
hi all....active/active. windows 2003 sp2. two nodes. two instances, each on a separate virtual server. my msdtc resource is in the cluster group. when i have the cluster group on one node, the sql instance that is running on the other node can't see DTC. Makes sense since the service is not up, but is this a problem? Seems strange to have a red stop sign on my dtc icon in sql management studio. I suppose I won't be able to run Distributed Transactions on that node, which kinda stinks. Wondering if anyone has seen a workaround.
I have setup a trigger to update records on a linked server, the link works fine and I can query tables on the remote server. However when my trigger activates I get the following error
The operation could not be performed because OLE DB provider SQLNCLI for linked server "NHS" was unable to begin a distributed transaction.
OLE DB provider SQLNCLI for linked server "NHS" returned message "No transaction is active"
I've followed a microsoft KB article and installed MSDTC on both servers, what else do I need to do?
HelloI had a question reagrding MSDTC usage. I know that MSDTC will enlisteach connection transactions as it's own (take ownership) andcommit/abort accordingly.However I'm not sure what would happen where I have a stored proc withinput parameters and 2 Delete commands on 2 different tables. In thiscase, would MSDTC also enforce ACID rules when 1 cmd succeeds and 2ndaborts ? In the script for the Stored Proc, there is no checking for@@ERROR value. There are just DELETE statement and a plain RETURN.thanksSunit
As newbie in server country I try a course example to test a distributed transaction accessing both SQL Server 2005 and Sql Server 2005 Express.
But I get an error message saying: --->MSDTC on server is not available
I Internetted somewhere that MSDTC stands for TransactionManager service. If I look in the 'Services' list I do not see something like MSDTC, so I think it is not installed or started.
Today we installed on MS Cluster (W2k3) and SQL Server 2000 a MSDTC Service. The installation was succesfull, but wenn we try to move the group, then it failed. Because we have only 2 Disks on the cluster one for the Quorum, the other for the Sql Server. We installed the MSDTC as a Resource on the Quorum Disk. The other Thing, wenn we start the firts node all is running on the first node, but we cannot move. Wenn we start the second node all is running on the second node, but we cannot move the Group which contain the Msdtc resource.
High level question: Is there a way to rollback a transaction without failing a task?
Here's the scenario:
A single foreach loop contains a sequence container. The sequence container has its TransactionOption set to "Required." All activity happens within the sequence container. This is so that each iteration of the foreach loop is in its own transaction space. Now the catch. In the sequence container I run a few tasks, but more importantly, at the end (final task before the next foreach iteration) I run a Script Task to compare the values of two variables to see if they match. If they do, then all is well; move onto the next iteration. If they don't (and this is where my problem lies), then I need to roll back the current transaction without halting the foreach loop's iterations.
Is the best idea/approach to increase the value of MaximumErrorCount for the parent/package and set the Dts.TaskResult to Dts.Results.Failure, or is there a way in the script task that I can roll back the transaction and set Dts.TaskResult = Dts.Results.Success??
I am trying to do something simple to test TransactionOption. I have a ScriptTask (out of the box), which runs fine. To test TransactionOption, I set the Package Properties TransactionOption = Required. Straight away the package fails with the following message
Error: The SSIS Runtime has failed to start the distributed transaction due to error 0x8004D01B "The Transaction Manager is not available.". The DTC transaction failed to start. This could occur because the MSDTC Service is not running.
I am running this on my Laoptop, which has XP Pro with SP2.
I checked the services and MSDTC and it is running fine. I have checked the Event Viewer and saw the following messages... One is Information and the other is Error
Information (Disk - Event ID 2444) ---------------------------------------------- MSDTC started with the following settings: Security Configuration (OFF = 0 and ON = 1): Network Administration of Transactions = 0, Network Clients = 0, Inbound Distributed Transactions using Native MSDTC Protocol = 1, Outbound Distributed Transactions using Native MSDTC Protocol = 1, Transaction Internet Protocol (TIP) = 0, XA Transactions = 0
Error (Devices - Event ID 4437) ------------------------------------------------ The account that the MS DTC service is running under is invalid. This can happen if the service account information has been changed using the Services snap-in in Microsoft Management Console (MMC). MS DTC service will continue to start. Please make sure that the MS DTC service account information is updated using the Component Services Explorer.
I have checked Component Services. All looks fine from what I can see.
[Microsoft][ODBC SQL Server Driver][SQL Server]The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "DUL41" was unable to begin a distributed transaction.
If I use query analyzer (or whatever we're calling it now) to connect to server 1 and run the statement, it works fine. But, SQR is connecting via ODBC (that's different) and also is SQR.
I'm also not 100% sure all of the new MSDTC aspects are configured correctly, but I've gone through the settings a few times. Right now, I pretty much have everything set about as open as possible (these are test servers on the same network) and am still getting the error.
Any help, or ideas I could try, would be great. Thanks.
Here is the situation. We have a .Net application that some consultants developed several years ago. They made use of DAO for database access, using some inbuilt classes like ContextUtil to get a transation environment.
Until last weekend, the envorinment was:
Web application on IIS5 / Windows 2000 Advanced Server
Database on SQL2000 on Windows 2000 Advanced Server
We switched over to a new database server environment - a cluster of two Windows 2003 servers wth SQL Server 2000. This required Active Directory to be set up on the two database server machines.
Everything worked but this particular application - where it goes to update the database. It appears (but since I haven't yet been able to rebuild the .Net solution) that the error - "Object reference not set to an instance of object." is in fact a spurious error caused when the transation tries to roll back.
I have spent about 10 hours on this, and have come to the conclusion that the fact I have MSDTC involved on a database server that is in an AD domain, while the web server that is issuing the transaction is outside that domain is the cause of the problem. Now, I don't want to put AD on the IIS 5 web server - we are migrating this to a new Win2k3/IIS6 server in 5 or 6 weeks time.
Any suggestions? If I have to, I can move the database for this particular app back to the non-clustered Windows 2000 server (which is also outside the AD domain).
I have a multitier app running 24 x 7...All is running ok until the server delay too much to respond when I'm trying to add the records, so I start to receive erros from the msdtc and the transaction is aborted...How can I resolved this trouble? I'm not sure if the cause is too long response from the server, but I have noted that in some moments the server is busier than when it's running ok...just for clearing this, my app have a maximum of 5 threads each one create an transactional objects to process the new entry.
I just uninstalled SQL 6.5 from my server (Now totally running in 7.0 Mode) and now I can't get the MSDTC service to start again. I get the error "Could not initialize the MS DTC XA transaction manager" (In Application Log)... and error "The MSDTC service terminated with service-specific error 3221229574." (In system log). I believe that somehow MSDTC got uninstalled and I don't know how to reinstall only MSDTC? Any suggestions would be appreciated...
Is there any way to set up name resolution for DTC when there are two servers with the same name? I have three servers - two production systems named "SQL" and an archive system "DMART". I want to run DTC procedures to archive data from both SQL's to the DMART. Is there any way to set up the DMART so it can properly resolve the names from each of the SQL's? They are on separate networks, but unfortunately have the same NetBIOS name.
Does MSDTC auto-install with the plain vanilla version of SQL Enterprise? Or do I have to install it later?Do you know of any links that reference specifically SQL 2012 stand-alone server installs of MSDTC?
