----------------------------------------
Thanks guys for looking into this. But I it looks like I still can not communicate the
issue properly.
After this step I waited until the TX recovery kicked in (runs every
120 secs)
The whole point is that it is possible for the other consumer to get the message BEFORE
periodic recovery runs (if configured at all). The second receive (step 9) is an
independent consumer who may connect at any time. Actually to execute clean test the JBM
recovery should be initially turned off. I did not mentioned it as assumed
"clean" JBoss 4.2.2 + JBM 1.4.0 SP3 will not have it. Eventually I turned it on
at step 11.
The scenario ">After this step I waited until the TX recovery kicked in" is a
different from the test and it works the same way on JBoss 4.2.2 that I am using. So I am
not optimistic that newer version will fix the problem. I guess I will try it anyway.
JTA-prepared message delivered to other consumer.
--------------------------------------------------
Key: JBMESSAGING-1440
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1440
Project: JBoss Messaging
Issue Type: Bug
Environment: JBoss 4.2.2 + JBM 1.4.0.SP3. Windows XP.
Reporter: szhigunov
Assignee: Tim Fox
Fix For: 1.4.0.SP3.CP05, 1.4.2.GA
Attachments: myxatest.zip, myxatest1.zip
The problem is that when fully prepared tx1 fails in the commit phase, JBM delivers the
message second time in tx2, while tx1 is still in progress. Eventually recovery commits
tx1, so the message gets delivered and committed twice.
The attached test (myxatest.zip) is a clean JBoss 4.2.2 + JBM 1.4.0 SP3 with my test
MBean: jboss-4.2.2.GA\server\messaging\lib\myxatest.jar (code and source) +
jboss-4.2.2.GA\server\messaging\deploy\myxatest-service.xml.
Steps to reproduce the problem:
1. Start the server.
2. Go to JMX console + myxatest + service=Test. Invoke send.
3. Go to JMX console + jboss.messaging.destination + name=A.service=Queue. Verify
MessageCount=1.
4. Go to JMX console + myxatest + service=Test. Invoke receive. That will start XA
transaction; enlist DummyXAResource; get JMS connection from JCA and receive message.
DummyXAResource sleeps 60 sec inside the commit call.
5. Verify that DummyXAResource prints "DummyXAResource commit start sleeping for 60
sec" message.
6. Go to JMX console + jboss.jca + name=JmsXA,service=ManagedConnectionPool and invoke
stop(). Check that DummyXAResource finished commit and printed "DummyXAResource
commit end" message. JBM commit fails.
7. Now we have fully prepared JBM transaction in progress. You can see one record in
JBM_TX.
8. Go to JMX console + jboss.jca + name=JmsXA,service=ManagedConnectionPool and invoke
start().
9. Go to JMX console + myxatest + service=Test. Invoke receive again. Same message
delivered again. And this is wrong. Wait for a minute and let transaction finish
successfully.
10. Got to JBM_TX and verify that transaction is still there (nobody recovered it!).
11. Stop server, enable JBM recovery, start server. In couple minutes the original
transaction is found and committed (second time). JBM_TX is empty.
