DT require Oracle9i client and Oracle Services for MTS software

"Distributed Transactions require Oracle9i client and Oracle Services for Microsoft Transaction Server software."
I get the error above when attempt to run a COM+ transaction accessing Oracle9i. I'd been checked the installation of Oracle9i and Oracle Services in the client computer and it is ok.
I am using Windows Server 2003 and the database server is on another Windows Server 2003. The database is Oracle9i Enterprise Edition.
At Stanford's web site (http://www.stanford.edu/dept/itss/docs/oracle/9i/win.920/a95496/ch1.htm#1079911) I found Oracle's documentation that explains this, but it didn't worked for me.
Oracle Services is installed in both machines.
The Oracle MTS Recovery Service is running.
The COM+ component is registered.
When I use the same component with SQL Server 2005 beta 2 it works fine. What else do I need to do?
Thanks in advance.

Hi.
I have the same problem, one which works and another which don't (almost though).
I got most of it to work by taking the mtsservices registry entry from the server that works and put it on to the other after i have made the service in Oracle management console for mts.
Now i can search, delete, change but not make a new entry into the database.
And thats where i'm stuck now.
Hope it helps a bit..

How to install Oracle Services for MTS (9i)

OK, I'm confused. I thought installing OraMTS components would be the same in 9i as in 10g.
In 10g I load the universal installer, and Oracle Services for MTS is present as a tickable, installable option
If I load the 9i installer (or point the 10g installer at the 9i stage directories) the option for Oracle Services for MTS just isnt there as a tickable option
How did you guys with 9i get the installer to put MTS on? (oramts.dll and it's friends)

From the base 9.2.0.1 media, start up OUI, choose Custom install type and tick Windows Interfaces (installs odbc, ole db, oramts, ...). If you have Metalink access, you may want to apply a patch set e.g. 9.2.0.7.
You can get 9.2 ODAC (which also includes Oracle's .Net Data Provider), from http://www.oracle.com/technology/software/tech/windows/odpnet/utilsoft.html to install just the Windows Interfaces directly, or to upgrade these files in a patched Client (patch sets seems to not affect/update these dlls).

MSDTC, Vista, Oracle Services for MTS and TransactionScope

Hi there,
We're using .NET 2.0 TransactionScope on a Vista client. By default this will create a distributed transaction using MTS which will then be proxied using Oracle Services for MTS. However we consistently get the following error:
ORA-00161: transaction branch length 100 is illegal (maximum allowed 64).
According to this thread http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=943955&SiteID=1 Microsoft made some changes in MSDTC in Vista which are likely to have caused this problem. They say they were co-ordinating with Oracle to determine an appropriate fix.
Is this an acknowledged issue? Has it been fixed and if not, when will it be fixed?
Kind Regards,
Dean Ward

FYI, the following code reproduces the issue...
using (TransactionScope txScope = new TransactionScope())
using (OracleConnection oracleConnection = new OracleConnection("Data Source=Test;User Id=Test;Password=Test"))
oracleConnection.Open();
using (OracleCommand oracleCommand = new OracleCommand("SELECT 'Test' FROM Test", oracleConnection))
oracleCommand.Connection = oracleConnection;
using (OracleDataReader oracleDataReader = oracleCommand.ExecuteReader())
while (oracleDataReader.Read())
System.Console.WriteLine(oracleDataReader.GetString(0));
txScope.Complete();
}

How to get "Oracle Services for MTS" working?

I've implemented the microsoft code example (see at the bottom) for the use of distributed transactions (with system.transactions and MTS support). The code works fine as long as I use only MS sqlserver.
Well, I tried one connection to an oracle database and one connection to the sqlserver - and here the trouble starts ;-)
Oracle doesn't care about the transaction. After the command is executed the changes are made to the oracle database at once (no commit has occured at that point) even if the second command isn't successfull.
I suppose at the moment that the problem must be something around the interaction between MTS and oracle database, more precisly the oracle Services for MTS.
I've installed the odp.net client (ODAC1020221.exe).
The installer tells me that oracle data access components 10.2.0.2.21 and within the Oracle Services for MTS are installed.
But I cannot find a service with that name in the service list, OracleMTSRecoveryService is listed, but I'm not sure if that's the right one.
So here are my questions:
What's the name for 'Oracle Services for MTS' in the services list?
Do I have to install more than the odp.net client to get the MTS support running?
Is there a mistake in the code I'm running?
any help is welcome ...
thanx in advance!!!
And here's the code I'm working with:
[Transaction(TransactionOption.RequiresNew)]
public class Worker : ServicedComponent
[AutoComplete]
public void Test()
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew, new TimeSpan(0, 5, 0)))
DbProviderFactory theFactory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
using (DbConnection connection1 = theFactory.CreateConnection())
try
connection1.ConnectionString = ".........";
connection1.Open();
DbCommand command1 = theFactory.CreateCommand();
command1.Connection = connection1;
command1.CommandText = "Insert into user (name, surname,benoid) values ('hans','wurst','32315134512345')";
object returnValue = command1.ExecuteNonQuery();
using (SqlConnection connection2 = new SqlConnection("Data Source=localhost;Database=UserManagement;Trusted_Connection=true;"))
try
connection2.Open();
//this command fails
SqlCommand command2 = new SqlCommand("Insert into uuuu (name, vorname) values ('hans','wurst')", connection2);
object retValue = command2.ExecuteNonQuery();
catch (Exception ex)
return;
catch (Exception ex)
return;
scope.Complete();
}

hey what's up you figured out your problem with M$DTC/Oracle 11i with ODP.NET trying to do a TransactionScope?
I saw your problem - and I ran into the same.
Re: 10g Express + ODP.NET (version 2.111.6.20) > support TransactionScope?
Trying to install "Oracle Services for MTS" not sure how but working on it now. Doc looks old however,

Did you get pass this already?

Oracle Services for MTS on multiple servers - does not work

I am having problems with running transactional component (COM+) using Oracle Services for MTS.
I've been through pretty much all the messages in this forum, and I believe that I have
configured things correctly. Here are the details. Sorry for the long post. I wanted to give as much details as possible.

Ganesh,
From the trace provided, it appears that the OraOLEDB had problems loading the OraMTS.DLL appropriately. Can you check to see if the OraMTS.DLL is in your %ORACLE_HOME%\bin and your PATH is set with %ORACLE_HOME%\bin included?
Another possibility is that an older version of OraMTS.DLL resides in your
%ORACLE_HOME%\bin. If you invoke "dumpbin /exports oramts.dll" at the DOS command line, one exported function should be called "OraMTSSvcEnlistEx". If you don't see this, then that means you should try reinstalling OraMTS 8.1.7 again.
Hope that helps.

I can't start Oracle Services for MTS

Hello there, Oracle users!
I am new here, as new to the Oracle technology. We are developping a
software which must be transaction compliant, and we're on microsoft
platform, and thatswy we're using sql2000 and microsoft transaction
server for our application server components.
But one of our clients wants to use oracle 8i db as the resource manager. We had to make the proper work mts with oracle. I've red all of the oracle documentation within this topic, and i successfully installed
the Oracle Services for MTS on our development machine at the workplace.
(created the mts_proxy_info table, granted the specific roles to a specific db user, the specific privileges, and so on), and
it is working nicely, the log says "accepting new enlistment requests",
everything is wonderful.
But at the client, i repeated all of the steps (the only difference is,
that they have the server on a HP-UX machine instead of winnt and i had not access to the oracle server, i just gived the sql script to the oracle dba guy there (maybe he missed something?)), and when i wanted to start the oracle services for MTS on the Application server, the log says this: "incorrect password, or username". I really don't
undestand it, because i can connect through the OLEDB driver with the
specified username, password and Service name. (in a datalink (udl), for example)
If anybody had an idea i would be very happy
thanks in advance,
daniel szabo
ps: the app server config is:
nt 4.0 server
sp 6
option pack 2
iis 4
mts 2
script host 5.5

Daniel,
In pre-8.1.7.4.0 beta implementations, your application server e.g. IIS or MTX.EXE hosts MTS transactional components. When such components acquire OLEDB or ODBC connections to Oracle and external service setup for that database i.e. OracleMTSService<id> joins the MTS transaction on behalf of the Oracle database which quite often runs on a non-Windows platform e.g. Solaris. We restrict each database to have one and only such service. This brings in scalability and availability issues. In 8.1.7.4.0 we have embedded the transaction join and commit logic in the clientside dll. There is no OracleMTSService<id> for a given database. The only service needed is a recovery service one per Windows machine on which Oracle Svcs For MTS is installed. This service is automatically created on installation of the product and doesn't connect to the databases. Instead the involved databases connect to the service via HTTP to resolve any MTS-related transactions that are in-doubt.

Error with VB, Ora ODBC 8.1.6, MS Tran Server and Ora services for MTS

I am getting VB error -2147168246 "Failed to enlist global transaction" from a VB middle tier component loaded in MS Tran Server. The VB error also mentions MS OLEDB Provider, however, I am using Ora ODBC 8.1.6, MS Tran Server 2.0, Ora Services for MTS (8.1.6) and Ora 8.1.6 for Win NT database. The VB middle tier component is marked as Requires Transaction. When the error occurs, the component has performed 3 SELECT's, a DELETE FROM, 3 more SELECT's, and then fails on a 4th SELECT. All of these activities are happening in this one VB component - it is not making calls to other components. Any ideas?

Thank you for your response. To answer your question, no, the SELECT statements do not involve any LOB's. With respect to the "Failed to enlist" error message, the dialog box mentions the Microsoft OLE DB Provider. We are using Oracle's 8.1.6 ODBC Driver and our connection string in VB 6.0 uses the DSN= syntax; we don't expicitly have the Provider= syntax in there. One of our many questions is: Given the above, is the Microsoft OLE DB Provider somehow being used, instead of Oracle's OLE DB Provider? We think not because we use Oracle Services for MTS and its trace file shows some transactions enlisted and completed, but this is a deduction - we don't really know what's happening behind the scenes. Another question we have is: When installing the Oracle 8.1.6 database on Win NT 4.0, there is a step where we must choose communication protocols. We have been selecting just TCP/IP. I read in OTN that Oracle Services for MTS talks to Microsoft's DTC using Named Pipes. We are now wondering if we should have included Named Pipes as a comm protocol when installing the DB.

Installing Oracle Services for MTS (9.2) on a 8.1.7 Database

Hello,
I'm trying to run the script oramtsadmin.sql which comes with the Oracle Services for MTS 9.2 on a 8.1.7 database.
When trying to compile the UTL_ORAMTS package I get the following error:
The following error has occurred:
PACKAGE BODY MTSSYS.UTL_ORAMTS
On line: 0
PLS-00908: The stored format of UTL_ORAMTS is not supported by this release
Any idea where I can find a copy of this wrapped package that can be compiled on a 8.1.7 database ?
thx,
Piet Neyrinck

I have the same problem. The documentation sayes that it will work with 8.1.7, but when I run the script I get the same error

Oracle Services for MTS

While going through documents I came to know that it is not required to configure the Services while using Oracle 9i client. But when I'm running TestOracleXaConfig.exe, it's saying "Trying to load XA73.dll. Load Library on XA73.dll failed."
How can change it to oraClient9.dll?
In the registry I changed OracleXaLib to "oraClient9.dll" under ....HKEY_LOCAL_MACHINE->SOFTWARE->MICROSOFT->TRANSACTION_SERVER->LOCAL_COMPUTER->MY_COMPUTER.

Understanding on Oracle services for Microsoft Transaction Server frm dba point of view

Hi ALL,
i read : -> https://docs.oracle.com/database/121/NTMTS/recovery.htm#NTMTS003
Need help to further confirm my understanding on what i read.
I am coming from the DBA angle... .
the functionality of the Microsoft Transaction server is integrated within the operating system as a COM+ server and as a .NET server, "
can i say these is the application servers ?
and the Microsoft Transaction distributed co -ordinator components is part of it.
Question, i don't install the Oracle Recovery Services on the above system right?
Question 2, as a dba, my only concern is to make sure the Oracle Services for Microsoft Transaction Server is installed. Is this correct ?
plus making sure to create the OraMTS administrator to run the recovery job to check for in-doubt transaction.
Question 3:
is this Oracle services for Microsoft Transaction Server used only when an application useses multiple databases in an env?
Can i say that when there is no user MTSSYS in my database, Oracle services for MTS is not used?
The reason why i ask is i am upgrading/ migrating my database and this database don't work with more then 1 database or the application does not work with more then 1 databases.
I ask the apps team all they say is that they are also not too sure. Thus need help/ advice.

Vista. Are you using ODAC for Windows Vista?
Found here:

look for "Oracle Database and ODAC for Windows Vista"
or
ORA-00161: transaction branch length string is illegal (maximum allowed string)
Cause: An external transaction branch ID with a length either too large or 0 was passed in.
Action: Report the problem to your external transaction coordinator vendor.
