MDB transaction getting silently rolled back?
I have an MDB that is doing a delete of a database record in the onMessage method.
It seems to work fine. I see no errors in the log, in fact I have some debug
statements that indicate everything was completed normally. I even do a count
sql using the same where clause and print the results and see a '0'.
However, when I check the database, the record is still there.
It seems as if the transaction is getting rolled back somehow. The MDB is transaction
required/container tx. I never setRollbackOnly anywhere.
The topic was originally published in a transaction that was rolled back, if that
makes any difference. In fact, the point of the MDB is to clean up a record that
was created during the transaction but not within the transaction.
Any help is appreciated!

It turned out that the MDB was using a different connection pool than it should
have, which was pointed to an old copy of the database. So it wasn't really rolling
back, it really was deleting records as desired, just in the wrong database.
Thanks

Transaction is not Rolling Back in Stateless Session Bean
Hi,
I am using UserTransaction in Stateless Session bean .
Transaction is not rolling back.
The following code is writen in stateless session bean. In UserTransaction i am
calling Two methods of another stateless session bean.
The problem is if doJob2() method fails, doJob1() method is rolling back. These
two methods consist of SQL statement with different Connection Object from TXDataSource.And
session bean(TestSession) is set to CMT, attribute as "Required".
try{
Context ictx=new InitialContext();
TestHome home=(TestHome)ictx.lookup("TestSession");
utx = sessionCtx.getUserTransaction();
utx.begin();
TestRemote remote=home.create();
remote.doJob1();
remote.doJob2();
utx.commit();
}catch(Exception e)
try{
utx.rollback();
}catch(Exception ex)
System.out.println("unable to rollback"+ex);
if any SQL Exception as occured in doJob2(), its calling method utx.rollback()
in catch block. but SQL statements executed thru. doJob1() are not rolling back.
what might be the reason?
thanks
Ranganath
Thanx Priscilla ,
Transaction is working.

Transaction - the subprocess rolling back parent JTA
According to Oracle documentation,
"if the caller partner link specifies transaction=participate and the subprocess also specifies transaction=participate, the subprocess rolls back the client JTA transaction."
But what I experience is if I just set transaction=participate for the partner link alone (and not having transaction=participate in the subprocess), when the subprocess rolls back, it rolls back parent JTA transaction also.
In fact, if we have just transaction=participate for the partner link (and not having transaction=participate in the subprocess), then the rollback in either Parent or Subprocess, is rolling back both Parent and Subprocess.
Can somebody provide the exact usage of using transaction=participate at the subprocess level?
Thanks,
JoeJoe,
You are seeing expected behaviour. Even though both flags are called "transaction" and both are set to "participate", they do different things.
By specifying transaction=participate on the partner link, you are instructing the subprocess to enlist in the transaction. When the subprocess starts, it will then enlist itself. That's all. Now if a rollback occurs, all participating processes will be rolled back.
If you specify transaction=participate at the process level, it has a different effect, and doesn't affect whether or not the transaction is rolled back or not. As I said in the previous paragraph, if the partner link specified transaction=participate, the subprocess will roll back if a rollback is issued, no matter what other settings you have.
So what effect does that setting have at the process level? According to the doc:
When transaction=participate, the process produces a fault that is not handled by fault handlers, which calls the transaction to be rolled back.
This is not exactly crystal clear, to me, anyway. In practice if this is set and your subprocess throws an unhandled fault, it triggers a rollback instead of throwing a fault as it normally would. This exception goes immediately back to the calling process since it is participating on the transaction as well.
If the property is not set, and the subprocess throws an unhandled fault, you get the normal behavior. Namely, the process will be flagged as faulted, and the calling process will wait until it gets a transaction timeout (no relation to the JTA transaction we're talking about here).
It's a simple test. Create two processes, then run it twice. Once with that property set, and one without.
The key is to remember that although they are both called "transaction=participate", the effect they have is very different. It was probably not a good move to use the same name and value like that. Hope this helps.
Regards,
Robin. -

Can't install itunes 11.0.1 on windows 7...get a Rolling Back Action message
Hi...I cannot install iTunes 11 on my Windows 7 PC. The installation goes all the way through and I get a "Rolling Back Action" dialog at the end and the progress bar just goes backwards.
Why is this happening?Not an error that I've seen. What stage of the process are you at when this happens?
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

On the server, we have implemented SessionSynchronization to monitor the transaction. afterCompletion method gets a boolean value "true" indicating that the transaction was comitted.
Any database operation that was successful before the erroneous case was saved in DB.

Transaction Process not rolling back
Hi Experts,
I am testing the Transaction Process which uses a DB Adapter (which calls a procedure) to insert data into a table. There are 2 fileds in the table (employee id and employee name) and in this employee id is the primary key. In the same scope I invoke this DB Adapter PL twice and for the first invoke it went fine but for the second invoke it has thrown me a unique constraint exception (as again I am passing the same data). I am catching the exception with a catch all block which is working absolutely fine.
The problem is in the table I am getting the data entry for the first invoke which should have roll backed as i am using the *'transaction=participate'* property and respective changes have been done in bpel.xml for supporting the transaction.
There should be no entry in the table but yet I am getting it. Please help me.
Where could I have gone wrong?????
I am using BPEL-10.1.3.1 version.
Thanks in advance.
Cheers,
Ankit
Edited by: user11083689 on Apr 24, 2009 4:41 AMhi,
There are two mechanisms to force a rollback from a BPEL process.
Explicitly — throw a bpelx:rollback fault within your flow:
<throw name="Throw" faultName="bpelx:rollback"/>
Invoke a partner link that marks the JTA transaction for rollback only.
For example, in Oracle SOA Suite for 10.1.3.1.0, if Oracle BPEL Process Manager invokes an Oracle Enterprise Service Bus (ESB) flow that in turn fails to call a Web service endpoint, the JTA transaction is marked for rollback. Since the Oracle ESB flow enlists its local transaction in the JTA transaction, a rollback on the JTA transaction impacts Oracle BPEL Process Manager's ability to dehydrate (as the JTA transaction is used by Oracle BPEL Process Manager for persistence).

Transaction doesn't roll back to Oracle
Hello, I would like to ask does webloogic support transaction controlled by client

Any ideas?

Thanks for you reply. I am new to transaction.
The version i am using is 7.0. I get the UserTransaction by ctx.lookup("UserTransaciton......)
where ctx is the InitialContext.
You are right, i found that the transaction is committed at each method.
If i call setRollBackOnly() before calling the bean method, the transaction
cannot committed.
But it is meaningless to me since the transaction should be able to roll
back at any points before the UserTansaction.commit();
TX-SUPPORTS, TX_REQUIRES....are you talking about the deployment descriptor?
I have check the deployment descriptor, the transaction attr is Required.
The rollback() method doesnt work. Are there any things missing?
Thanks

Statement in Transaction Does Not Roll Back
I have a group of MySQL statements in a method of a Java application.
I include an SQL error in the last statement to test the rollback of the transaction.
All the statements roll back, EXCEPT for the one detailed below.
The MySQL table:
CREATE TABLE Counter (
number INT( 4 ) NOT NULL DEFAULT 0,
account_id VARCHAR( 12 ) NOT NULL PRIMARY KEY
) ENGINE = InnoDB;I have run the staement as a PreparedStatement and a Statement:
PreparedStatement:
String updateCounterStr =
" UPDATE Counter " +
" SET number = number + 1 " +
" WHERE account_id = ? "
updateCounter = con.prepareStatement ( updateCounterStr );
updateCounter.setString( 1, accountID );
int uc = updateCounter.executeUpdate(); Statement:
Statement updateCounterStatement = con.createStatement();
int updatecounter = updateCounterStatement.executeUpdate(
"UPDATE Counter SET number = number + 1 " +
"WHERE account_id = \'" + accountID + "\'"
con.setAutoCommit( true ); // ------------------------------------ Transaction ENDS
updateCounterStatement.close();
// updateCounter.close();
... several more
con.close();
} catch(SQLException ex) {
System.err.println("SQLException: " + ex.getMessage());
if (con != null) {
try {
System.err.print("Transaction is being ");
System.err.println("rolled back");
con.rollback(); // < ------------------------------------ con.rollback() HERE
} catch(SQLException excep) {
System.err.print("SQLException: ");
System.err.println(excep.getMessage());
} // ---------------------------------------- END the methodIn both cases Counter is incremented, but does NOT roll back.
The other statements in the transaction do roll back,
I am using:
mysql Ver 14.12 Distrib 5.0.18, for apple-darwin8.2.0 (powerpc) using readline 5.0
on Mac OS X 10.4.x
I would greatly appreciate a solution to this problem.
Many thanks in advanceI think autocommit is true by default. Also, it looks like your'e setting it to true, and then executing more SQL.
Explicitly set it to false, and DON'T set it back to trueif there's any chance you're going to want to rollback after that. -
Fading Rollover Widget - How to get it roll back in again on Rolloff?
Hey there,
sorry for that confusing title
For a nice menu effect, I would like to use the Fading Rollover Widget.
As fading type I went for "horizontal", however, once it has completed this action, the menu does not roll back in again on Rolloff.
Is there a way to fix this?
You can visit the site at kundenservice.n90media.de/n90media (regarding the menu on top of the page).
-MarkusYou can use accordion menu , where menu items can be inserted in container.

Multiple Transaction with Fully Rolled Back
Hi there,
I've the scenario for a project that require multiple transaction as a subsequent process. I'll have one RFC Function Module that wrap multiple BAPI inside there. This RFC will be publish as a webservice and will be consumed by .NET application.
The problem that I've, the subsequent process will depend each other. For the example : Create SO, Purch Requisition, and with Reference to PR, I need to create the PO. So I need to commit the transaction for Sales Order creation before I can't continue to create the purchase order.
If there is a problem during the creation of PO, the Sales Order already committed to the database and I can't roll it back.
Any suggest, how I can handle this situation with concept of Complete the whole transaction and not at all if there is an error for one of the transaction.
Thanks in advance for any help.
Cheers,
DannyHi Danny,
Unfortunately this is the only option for you because you cannot rollback after you commit to the database. The other option would be to trigger Check BAPIs or BAPIs with test mode = 'X'....but that will be a problem for e.g. if you want to create a PO with reference to a PR created in the earlier step. If you can omit the part of creating with reference, then I think this is possible by first triggering BAPIs in test mode for all the documents that have to be created - if the whole chain is successful then you trigger BAPIs in update mode to post the docs (Commit) or else exit the process. Hope it made sense.
Cheers,
Sougata. -
How many of the transactions woill be Roll backed?
Hi friends,
Could you please clarify That How many of the transactions will be rollbacked when we say ROLLBACK....?
(For e.g., As a first transaction i used delete command to delete one row from a table of 10 rows....As a second transaction i used update command two times to update two records in the same table....Now i created one table ...after that i said rollback....So how many of the transactions will be rollbacked?)I'm sure blushadow has heard of all of those, but what does it have to do with the original question?

Transaction is not rolling back
I have statefull session CMT bean and I have a method
public void meth1() {
try {
dao1.method1(connection);
dao2.method2(connection);
} catch (SQLException ex) {
sessioncontext.setRollbackOnly();
throw (application exception);
If dao2.method2 raises sqlexception then whatever happend in dao1.method1 is committed. I have "Required" as transaction attribute for this session method.

How to rollback for application errors.
Thanks in advanceI've never used oracle, so I can't say what your setup should be, however...
databases can have transactions and the syntax is different between databases, e.g.
start {start the transaction}
update table X .....
rollback {rollback the transaction}
should not update the database
but if table X does not support transactions, you can't do this.
I had this problem with mysql, where everything worked fine until I had an exception or called setRollbackOnly. Some stuff would rollback (ovbiously cached in the app server), but other stuff wouldn't.
I configured the tables in mysql to support transactions and it all worked. -
Hello all,
I'm using the below code to send the notication using plsql package. It works fine and sends notification if i don't use '#FROM_ROLE' and 'SENDER' attributetext in the code. If i use them, i get the error message. Please advice
L_MESSAGE_TYPE := 'WFMAIL';
L_MESSAGE_NAME := 'OPEN_MAIL_FYI';
L_NID := WF_NOTIFICATION.SEND(UPPER(P_USER_NAME),
L_MESSAGE_TYPE,
L_MESSAGE_NAME);
WF_NOTIFICATION.SETATTRTEXT(L_NID, 'SUBJECT', P_SUBJECT);
WF_NOTIFICATION.SETATTRTEXT(L_NID, 'BODY', P_TEXT_BODY);
WF_NOTIFICATION.SETATTRTEXT(L_NID, '#FROM_ROLE', 'USERNAME1');
WF_NOTIFICATION.SETATTRTEXT(L_NID, 'SENDER', 'USERNAME1');
WF_NOTIFICATION.DENORMALIZE_NOTIFICATION(L_NID);
Thanks
KKHi KK,
What error you are getting when you set the attributes '#FROM_ROLE' and 'SENDER'?
when you set '#FROM_ROLE' then Wf_Notification.Denormalize_Notification(nid) API will be called. If the attribute is 'sender' then event 'oracle.apps.wf.notification.setattrtext wll be rasied. -
Container transaction NOT rolled back after a long period of time.
Hi, I am using Weblogic 6.1SP5 on RedHat 7.1 and I have seen an unexpected
behaviour with an MDB and I would like to know if there is any circumstance
in which a transaction is not rolled back automatically by the container
after the transaction timeout specified on MDB descriptor expired.
The fact is I have seen a thread locked for 3 entire days without any
exception being raised (the trans timeout was set to 900 seconds for
debugging porpouses)
Sadly I didn't thought on issuing a ps -ax and a netstat -np in order to see
if there was any connection active for any of the JVM threads.
As an aside note I had to throw a kill -9 to Weblogic's JVM in order to
completely stop it because using the standard "stopWeblogic.sh" script it
got stalled.
The only unusual thing that I can think of the MDB is doing is opening a
connection against a remote system via a socket.
My question is. Is it possible that a thread locked on I/O (in this case a
socket) to be out of control in terms of throwing at it a "Transaction
rolled back exception"?
I have modified my code in order to set SO_TIMEOUT on the socket just in
case the other peer hangs and never returns control. But I would like to
know the problem could be there.
I know for sure that at the time the thread stalled the other peer died
(exceptions on other MDBs trying to connect to remote system) but I expected
a "socket exception" to be thrown by the O.S. to the stalled thread instead
of having the thread waiting forever on that "open" socket.
Thanks in advance.
Ignacio.
While a tramsaction may be rolled back at the transaction timeout,
the thread is not stopped. The actual exception won't occur until
the MDB completes. If the MDB doesn't complete (as in this case),
you won't get the exception.
