1. Re: Jboss 3.2.7 JCA question.
weston.price Mar 29, 2006 12:51 PM (in response to madhav_inamti)I assume you are calling 'close' on your adapter. What is this RA actually doing on the back end?

2. Re: Jboss 3.2.7 JCA question.
madhav_inamti Mar 30, 2006 5:01 PM (in response to madhav_inamti)I am calling close on the Connection Handle and after we are done with the EJB, we are calling 'remove'.
I have been running the same test against JBoss 4 and everything seems to be ok. However this issue with Jboss 3.2.7
Is it that Jboss 4 is more forgiving than JBoss 3.2.7 or is it a bug in JBoss 3.2.7 ?

3. Re: Jboss 3.2.7 JCA question.
madhav_inamti Mar 30, 2006 5:31 PM (in response to madhav_inamti)The answer to your other question....
The adapter is calling COBOL programs on a COBOL server.

4. Re: Jboss 3.2.7 JCA question.
madhav_inamti Mar 31, 2006 2:22 PM (in response to madhav_inamti)It seems to be trying to passivate the stateful bean and the error is
java.io.NotSerializableException: org.jboss.resource.connectionmanager.NoTxConnectionManager$NoTxConnectionEventListener
Why is this passivation happening ? Could it be because some "remove's" were lost ?

5. Re: Jboss 3.2.7 JCA question.
madhav_inamti Apr 1, 2006 2:29 PM (in response to madhav_inamti)This happens on JBoss 4 too, after about 16 hours.
The same NotSerializable Exception and also take a look at memory consumption of Jboss classes
Here is the heap dump, when the passivation failure happens

6. Re: Jboss 3.2.7 JCA question.
weston.price Apr 1, 2006 3:06 PM (in response to madhav_inamti)At a quick glance, in your SFSB is the connection handle transient? It looks like when passivation occurs, it is trying to serialize your adapter.

7. Re: Jboss 3.2.7 JCA question.
madhav_inamti Apr 2, 2006 3:26 AM (in response to madhav_inamti)I think
org.jboss.resource.connectionmanager.NoTxConnectionManager$NoTxConnectionEventListener
is not serializable.
We would like to solve this issue for the customer.

8. Re: Jboss 3.2.7 JCA question.
madhav_inamti Apr 2, 2006 4:26 AM (in response to madhav_inamti)Indeed it looks like that. the connection handle was not transient in the test code. I will make it transient so that the adapter or parts of it does not get serialized.
However, my question is why is passivation happening. I am calling an EJB method that calls COBOL comes back and a remove on the EJB takes place.
Could it be that a managed connection that was used to call COBOL was destroyed by JBOss before the remove on EJB happened ?

9. Re: Jboss 3.2.7 JCA question.
weston.price Apr 3, 2006 3:12 AM (in response to madhav_inamti)This is really now an EJB question. Submit a question in regards to passivation/activation. If I was to venture I guess, here is what I think might be happening. You may be getting timeouts/exceptions in your operations on of SFSB. In the case of an exception, you have to guarantee that the remove() operation is called (in a finally block). Something tells me that this might not be getting done. As a result, those instances remain in the pool and are subject to passivation. Then, they exception you are seeing occurs.
