Distributed transaction error in WL 7.1

Hi,
I'm trying to set-up distributed transactions for weblogic. We have a requirement
to go against 2 different databases within a single transaction.
My config.xml looks like:
<JDBCConnectionPool CapacityIncrement="1"
DriverName="oracle.jdbc.xa.client.OracleXADataSource"
InitialCapacity="1" MaxCapacity="2" Name="PAWSPool"
Properties="user=STARTESTDATA;url=jdbc:oracle:thin:@s0489dev.dev.schwab.com:1521:ACSTAR;password=STARTESTDATA;dll=ocijdbc9;protocol=thin"
RefreshMinutes="5" ShrinkingEnabled="true"
SupportsLocalTransaction="true" Targets="sps_space"
TestConnectionsOnReserve="true" TestTableName="DUAL"
URL="jdbc:oracle:thin:@s0489dev.dev.schwab.com:1521:ACSTAR"/>
<JDBCTxDataSource JNDIName="jdbc/paws"
Name="PAWSDataSource" PoolName="PAWSPool" Targets="sps_space"/>
and the pseduo code that produces the problem looks like this:
UserTransction.begin(); //assume valid lookup in jndi occurred already
Connection con = dataSource.getConnection(); //datsource obtained from jndi lookup
PreparedStatement ps = con.prepareStatement("sql string");
the error
HELP!!!!!

what is the error ? if you could cut and paste the log / stdout that shows
the error that could be useful.
Also did youmean to say you are using WLS7.0SP1?

Can not commit distributed transaction

Hi
We get error "can not commit distributed transaction" during
commit the transaction in which we have create NEW entities.
Update-transactions on existing enitites work correct.
Our problem is probably due to seauences for object IDs: we are using oracle native sequences:
<sequence name="SeqErrRecObj" strategy="nontransactional" factory-class="native(Sequence=BUYING.SEQ_ERRRECOBJ)"/>
As soon we use strategy="nontransactional" in managed environment,
we get "can not commit distributed transaction" error by creating new instance.
Switching to strategy="transactional" seems to eleminate this problem.
I did not found any hint in about this in documentation.
Can some one confirm our assumption that using nontransactional oracle sequences in manageg (WebLogic 9.2) environment
is responsible for "can not commit distributed transaction" error and "strategy=transactional" is the right solution.
Probably we are completely wrong and tehre is some other explanation for this error ?
kind regards
Andre Teshler

Hi Andre,
It sounds like you have not configured a non-transactional datasource. See section "4.2.1. Managed and XA DataSources" in the <kodo>/docs/jdo/pdf/manual.pdf. Connection is for the managed datasource and Connection2 for the non-transactional.

ORA-02042: too many distributed transactions

1. I have been working on a portal application for several weeks.
2. Portal is installed in 1 instance and my data is in another instance.
3. I've had no ora-02042 problems in the devt environment set up that way.
4. I've recently migrated the application/pages to a test environment set up that way.
5. I've been working in the test environment for several days with no problems.
6. For some portlets on some pages I'm now getting:
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>

7. I cannot find anything about this error in the db log files for either instance.
8. I've increased distributed transactions to 200 in the portal db and bounced
it. Still get the error.
9. No records in dba_2pc_pending or dba_2pc_neighbors in the portal instance.
10. I get the error in various reports and form LOVs at different times. Pages with a lot of portlets seem to be more prone to the error.
Here is a typical LOV error:

Why are these select statements being interpreted as distributed transactions? Note:1032658.6 suggests I "USE SET TRANSACTION READ ONLY". Is this necessary? If so how?
What puzzles me is that this set up has been working fine for several days. I don't know of any changes to my environment apart from me increasing distributed transactions.

Hi,
this is information from metalink:
The ORA-2042 indicates that you should increase the parameter
distributed_transactions.
The ORA-2063 indicates that this must be done at the remote
database.
Explanation
If the distributed transaction table is full on either side of
the database link you get the error ORA-2042:
ORA-02042: "too many distributed transactions"
Cause: the distributed transaction table is full,
because too many distributed transactions are active.
Action: increase the INIT.ORA "distributed_transactions" or
run fewer transactions.
If you are sure you don't have too many concurrent
distributed transactions, this indicates an internal
error and support should be notified.
Instance shutdown/restart would be a workaround.
When the error is generated at the remote database it is
accompanied with an ORA-2063. In this case the parameter
distributed_transactions must be increased at the remote
database.
If there is no ORA-2063 the parameter distributed_transactions
must be increased at the local database.

Errors in DB alert log for distributed transactions

Hi,
I am receiving the following type of errors regularly in one of our development databases:
Errors in file e:\oracle\product\diag\rdbms\agdev10g\agdev10g\trace\agdev10g_reco_16356.trc:

ORA-12500: TNS:listener failed to start a dedicated server process
ORA-12154: TNS:could not resolve the connect identifier specified

//      - Verify that the default context being used is correct by

Get error from SQL AGENT: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D024

I am running SQL Agent that executes an SSIS process from sql server1. The SSIS process executes its SQL/tables/sp’s against another sql server2.
I get an error after adding data flow tasks with transaction supported within a sequence with transaction required. The error, “The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D024 "The transaction
manager has disabled its support for remote/network transactions"
Prior to adding this sequence everything was working from sql agent, and there were other sequences with oledb destinations.
Everything works when running within SSIS Package.
I see this article on similar issue,
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/0bfa2569-8849-4884-8f68-8edf98a9b4fe/problem-to-execute-a-package-and-tasks-with-a-certain-transactionoption-property-i-need-help?forum=sqlintegrationservices
“I had similar issue and solved by setting the following on both the machines. Allow Remote Clients, Allow Remote Administration,
Allow Inbound Clients, Allow Outbound Clients, and TIP are enabled in Component Services/My Computer/Properties/MSDTC/Security Configuration.”
I don’t want to remove transaction required for the “Remove Duplicates from Staging” sequence.
Anyone seen this?
Greg Hanson

DTC was running on remote computer. The problem was it was no longer accepting transactions from remote servers. This was in SSIS so I had to turn to "Transaction Supported" for all Data Flow Transactions.

Linked Server : SQL 2012 to 2000 error - Microsoft Distributed Transaction Coordinator (MS DTC) has stopped this transaction.

Hi all,
If any one has worked around this error and can help ?
Msg 8522, Level 16, State 3, Line 1
Microsoft Distributed Transaction Coordinator (MS DTC) has stopped this transaction.
I am trying to connect from sql 2012 to 2000 server. Established linked server using native client 10. I am able to see catalogs and database and table. Just when I am trying to query i am getting above error.
any help is really appreciated.
Thanks
Please Mark As Answer if it is helpful. \\Aim To Inspire Rather to Teach

Hi Logicinisde,
What the new error message do you get after using the workarounds in this
blog? Please post it for analysis.
Besides, as SQL Server 2012 has stopped connecting to SQL Server 2000 via linked servers, personally I recommend you upgrade SQL Server 2000 to a higher version to make your queries or ETLs efficient.

Hello,
I am not an expert in MSDTC but as we know,SQL Azure Database does not support
distributed transactions. This means that SQL Azure doesn’t allow Microsoft Distributed Transaction Coordinator (MS DTC) to delegate distributed transaction handling.
One common cause of MSDTC getting involved in Entity Framework applications is the fact that we close and reopen the same connection as needed (i.e. for each query that is executed).To avoid the stack from opening and closing the connection multiple times,
you can simply open the connection explicitly and run the queries in the same connectio.
The following thread is about a similar issue, please refer to:
http://answers.flyppdevportal.com/categories/azure/sqlazure.aspx?ID=d705a8cf-cba4-494c-96f6-96a136bd29e3
What's more, you can also try the workaround that involves setting the Enlist option of the SQL Azure connection to false. For the detail explanation, please refer to:Entity
FrameWork and SQL Azure

EJB 3.0 and JTA (Distributed transactions)

hi, first of all sorry for my english.
then :)
i'm working with JBoss Aplication Server an Oracle DataBase using EJB 3.0
i have no problem before ... but now i want work with multiple database and i wand to manage transactions ... how i understand JTA (Java Transaction Api) is a technology for it.

Problem: [Microsoft][ODBC SQL Server Driver][SQL Server]The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.

Hi Gurus,
I have this problem in my MS SQL Server 2012 that is running in SQL Server 2008 R2 Enterprise 64 bit.. Not sure why... Here is the full details of the error:

Still does not work. I have allow MSDSTC in my firewall list.
Hi dudskie,
Have you try to use DTCTester or DTCPing to verify MSDTC functionality over the network? Please refer to the following article:
Troubleshooting Problems with MSDTC:
http://msdn.microsoft.com/en-us/library/aa561924.aspx
Use the DTCTester utility to verify transaction support between two computers if SQL Server is installed on one of the computers. The DTCTester utility uses ODBC to verify transaction support against a SQL Server database. For more information about
DTCTester see How to Use DTCTester Tool.
Use DTCPing to verify transaction support between two computers if SQL Server is not installed on either computer. The DTCPing tool must be run on both the client and server computer and is a good alternative to the DTCTester utility when SQL Server
is not installed on either computer. For more information about DTCPing, see
How to troubleshoot MS DTC firewall issues.

Hope this helps.

ORA-00164 Autonomous and Distributed Transactions in Oracle 8i - Forms6i

Hi, in Forms6i I'm using Autonomous transactions (insert and update), and I want to use also a database link to make a query in a remote database (Distributed transaction). Even when this request are done in different PL/SQL within Forms6i, I get the error message ORA-00164 Distributed transactions disallowed within autonomous transactions. Is there a way to avoid this error message?
Thanx

Hello,
I had a similar Problem, when I tried to log errormessages while selecting by db-link.
I use pipes now to send the errormessages. The pipe is read at regular intervals and then I can Insert without using autonomous transactions.
I hope, this will help you

Distributed transaction using linked server not working in SQL Server 2008 64 bit

Hi. I have had an issue trying to get distributed transactions to work in SQL Server 2008 using a linked server. The error message I get is
OLE DB provider "SQLNCLI10" for linked server "pod1" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 3
The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "pod1" was unable to begin a distributed transaction.
My Environment:
Windows Server 2008 Enterprise 64 bit, SQL Server 2008 Enterprise 64 bit
Problem occurs with multiple different builds of SQL Server 2008 - I have been able to reproduce the problem with 10.0.1600.0, 10.0.1779.0 (CU 2), as well as 10.0.2531 (SP1)
I am aware that other people have had this issue and have reviewed all existing posts. I have verified that the MSDTC is configured correctly on both machines. I have also used DTCTester to verify that DTC is working correctly on all machines in question.
None of the mentioned resolutions has solved this problem for me.
I am not seeing this problem occur on my 32 bit test machines - it is only occurring if at least one of the two machines is 64 bit.

Hi All,
I realise that this topic may be a little bit out-of-date but if someone gets here from some search engine trying to find a solution for DTC problems, this MAY be useful.
So... I recently had the same issue, tried all the approaches described in KB and other articles, but it didn't help. Because my task to solve this was not of the highest priority I forgot about it for some time.
Today I was troubleshooting some other issue and, by accident discovered source of that first problem:
In the EventViewer I found Error entry logged by MSDTC saying:
"The local MS DTC detected that the MS DTC on vm-server1 (other machine name that also runs DTC - my comment) has the same unique identity as the local MS DTC. This means that the two MS DTC will not be able to communicate
with each other. This problem typically occurs if one of the systems were cloned using unsupported cloning tools. MS DTC requires that the systems be cloned using supported cloning tools such as SYSPREP. Running 'msdtc -uninstall' and then 'msdtc -install'
from the command prompt will fix the problem. Note: Running 'msdtc -uninstall' will result in the system losing all MS DTC configuration information."
So I followed suggestion and run:
msdtc -uninstall
msdtc -install
This solved my problems with DTC. Hope it will help someone.

ORA-02074: cannot ROLLBACK in a distributed transaction

I have a stored procedure that successfully creates a portal user when I run it with SQLPLUS.
However when I call the same procedure through ODP.Net, I get the following error.
"ORA-20001: ORA-02074: cannot ROLLBACK in a distributed transaction\nORA-06512: at \"PORTAL30.WWSEC_API\", line 1915\nORA-02074: cannot SET SAVEPOINT in a distributed transaction\nORA-06512: at \"PORTAL30.PRO_CREATE_WEB_USER\", line 28\nORA-06512: at line 1"
The portal version is 3.0.9.8.2 The stored proc is in the portal30 schema and I am connecting as portal30 user.
Any help is greatly appreciated...
Thanks.
The following is the code for the stored procedure:-
CREATE OR REPLACE PROCEDURE PORTAL30.PRO_CREATE_WEB_USER (
puser IN varchar2,
puser_last_name IN varchar2,
puser_first_name IN varchar2,
puser_group IN varchar2,

) AS
l_group_id number;
l_id number;
e_code number;
begin
l_id := wwsec_api.add_portal_user(p_User_Name => puser,p_Last_Name => puser_last_name,p_First_Name => puser_first_name,p_Portal_User => 'Y');
wwsec_api.activate_portal_user(puser);

wwsec_api.set_defaultgroup(p_groupid => wwsec_api.group_id (p_name => puser_group),p_username => puser);
commit;
exception
when others then
raise_application_error(-20001,substr(sqlerrm,1,200));
end;
The foll is the code I am using to call the stored proc.
private void createUser()
string retval ;
OracleConnection oraconn = new OracleConnection(Data Source=testdb;User ID=portal30;Password=portal30" );
OracleCommand cmd = new OracleCommand("PRO_CREATE_WEB_USER", oraconn);
cmd.CommandType = CommandType.StoredProcedure;
OracleParameter a_uid = new OracleParameter("puser" ,OracleDbType.Varchar2,20);
a_uid.Direction = ParameterDirection.Input ;
a_uid.Value = (txtUserId.Text).Trim() ;
cmd.Parameters.Add(a_uid);
OracleParameter a_last_name = new OracleParameter("puser_last_name" ,OracleDbType.Varchar2,20);
a_last_name.Direction = ParameterDirection.Input ;
if (( txtLName.Text).Trim() != "" )
a_last_name.Value = (txtLName.Text).Trim() ;
else
a_last_name.Value = " ";
cmd.Parameters.Add(a_last_name);
OracleParameter a_first_name = new OracleParameter("puser_first_name" ,OracleDbType.Varchar2,20);
a_first_name.Direction = ParameterDirection.Input ;
if ((txtFName.Text).Trim() != "")
a_first_name.Value = (txtFName.Text).Trim() ;
else
a_first_name.Value = " ";
cmd.Parameters.Add(a_first_name);
OracleParameter a_type = new OracleParameter("puser_group" ,OracleDbType.Varchar2,20);
a_type.Direction = ParameterDirection.Input ;
a_type.Value = (lstUserType.SelectedValue).Trim() ;
cmd.Parameters.Add(a_type);
OracleParameter a_passwd = new OracleParameter("password" ,OracleDbType.Varchar2,20);
a_passwd.Direction = ParameterDirection.Input ;
a_passwd.Value = (txtPassword.Text).Trim() ;
cmd.Parameters.Add(a_passwd);
try
oraconn.Open();
cmd.ExecuteNonQuery();
lblMsg.ForeColor = System.Drawing.Color.FromName("blue");
lblMsg.Text = "User Created.";
catch(OracleException e)
{ retval = e.Message ;
lblMsg.ForeColor = System.Drawing.Color.FromName("red");
lblMsg.Text = "Error Creating user" ;
finally
oraconn.Close();

Also note that remote procedure/function calls (e.g. from ODP.NET), do not support distributed transactions (i.e. a SAVEPOINT/ROLLBACK block within the PL/SQL procedure/function) before database version Oracle 9i.
So if you are using say Oracle 817 you must use the "OracleTransaction" object in ODP.NET instead.
