JBoss arjuna TransactionReaper don't rollback on timeout

Question

I'm working with an application that access an oracle database. Sometimes objects (rows) on that database are locked by process outside my application.

The problem I'm having is that when the transaction reaches the transaction timeout, arjuna coordinator tries to rollback the transaction but don't succeed in it

The stack trace is the following

09:15:42,494 WARN  [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsF

I'm using jboss-5.1.0.GA, Hibernate 3.3.1.GA and Oracle 9.2.08.

I have done several tests and while the row is locked the rollback don't work. It doesn't matter the time that have passed since the transaction timeout. If i unlock the row after the transaction timeout, the rollback starts at that moment.

I have done some research on the web but didn't find exactly the same error.

Thanks.

Answer 1

Finally I found the answer (here on stackoverflow). It doesn't solve my problem (because what is happening is the expected behaviour), but explains what is happening.

Transaction TimeOut EJB impact on the thread

Answer 2

Here I found how to enable arjuna logging on jboss:

http://germanogiudici.wordpress.com/2011/09/02/how-to-log-transaction-informations-in-jboss-4-2-3-ga/

I hope this helps to get more info on what is happening.

What I found till today, is that the workerThread that holds the transaction doesn't finish on cancel() method. But whith my current log level I can't see what is happening.

I will post more news after debug.

Note: the xml configuration for Transactions in jboss 5.1 is jbossts-properties.xml not jbossjta-properties.xml.
