[JBoss-user] transaction timeout problems
hi,
I am using jboss 3.2.1 with jetty.
When I am trying to create a CMP Entity Bean, the transaction is timing out.
My method call is somewhat like this -
public void createA(HashMap aHash){
Set keySet=aHash.keySet();
Iterator ite=keySet.iterator();
while(ite.hasNext()){
Integer id=(Integer)ite.next();
// here I create a new entity
AHome.create(aHash.get(id));
Collection BList=BHome.findByA(id);
Iterator ite2=BList.iterator();
while(ite2.hasNext()){
BObject bobject=(BObject)ite2.next();
// here I update an entity
bobject.setStatus(2);
}
Collection CList=CHome.findByA(id);
Iterator ite3=CList.iterator();
while(ite3.hasNext()){
CObject cobject=(CObject)ite3.next();
// here I update an entity
cobject.setStatus(2);
}
}
}
All this happens inside a session bean method, which is marked with
tx-attribute required. The entity beans are CMP 2.0 and all have a
tx-attribute required.
I am using Optimistic Concurrency with version column.
How can I diagnose what is going wrong here ?

[JBoss-user] Transaction timeout
hi, how can I increase a transaction timeout for a session bean and entity bean? regards, Rafal --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

From a previous answer to this question: From: Barlow, Dustin [EMAIL PROTECTED] In 3.2.1, in jboss_dist/server/target/deploy/transaction-service.xml you will find the following stanza: !-- | The fast in-memory transaction manager. -- mbean code=org.jboss.tm.TransactionManagerService name=jboss:service=TransactionManager attribute name=TransactionTimeout300/attribute depends optional-attribute-name=XidFactoryjboss:service=XidFactory/depends /mbean Change the 300 (in seconds) to whatever you want. I suspect this is the same for 3.0.6 as well. The comment about being the same for 3.0.x is not quite correct, it is in a different place. You will find the same definition for the MBean but in jboss_dist/server/target/conf/jboss-service.xml. I have tried changing this on a running system via the jmx-console and it seems to work. Just change the attribute value TransactionTimeout on the service service=TransactionManager under the jboss namespace. From my reading of the code of the TransactionManagerFactory I think you will also need to stop and start the service as well after changing this value (but I haven't verified any of this). brian wallis... --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

[JBoss-user] Transaction timeout setting not honored
I'm using JBoss 2.4.8 with Tyrex as the TM. In the Tyrex domain.xml file, I set the timeout to 360 seconds (6 minutes). In code, I set the transaction timeout to 600 seconds (10 minutes). After 120 seconds (2 minutes), the default timeout for Tyrex (http://tyrex.exolab.org/configuration.html), the transaction times out and an exception is thrown, stating that the transaction is no longer active. Right now, due to a slow connection, I need to be able to set the transaction timeout to whatever it takes to get the data that I want. With some performance tuning or an upgrade in the connection, I may be able to lower it, but I need it to be higher. I would appreciate any help in solving this problem.

[JBoss-user] Transaction Timeout
Hi All I have a StatelessSession bean which is been called by a servlet. Here is my problem. I have two browsers from which I make calls to the StatlessSessionBean method at the same time. At times this call at the same time causes a Transaction Time Out and then the RemoteException is thrown. Also my transaction attributes for the session beans as well as the entity beans are Required. Since the calls come from 2 servelets I believe they will have their own Transaction contexts. But why would this consequence calls to the bean cause a Transaction time out. Would appreciate any input from any one. Btw. I also tried giving the Isolation levels. But that did not help. Cheers and TIA Imran ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
[JBoss-user] transaction timeout and ctrl-C
Hi All... I have been doing some testing on a P166 with 64MB RAM running Debian linux. jBoss 2.2.1/Tomcat does remarkable well on this machine. However, when the machine gets very overtaxed, I see transation fialures due to transaction timeout. Thats fine. However, I have noticed that after a transaction timeout, jBoss seems to stop responding to CTRL-C and I can't shut it down, short of a kill -9. Has anyone else noticede this? Thanks...

[JBoss-user] Transaction timeout
Hi,
I am running JBoss 2.1 alongwith Jetty 3.0.2 / JDK
1.3.
We have a stateful session bean running with bean
managed transaction. It has got the transaction
boundaries set as follows:
getFirstName() is where the transaction is initiated
by UserTransaction.begin(). In getNextName(), the
transaction is committed by UserTransaction.commit().
Now, the two methods are invoked by two different
servlets. When the user calls the first servlet, it
calls the bean's getFirstName() method, and fetches
the values for us. When the user clicks on the "Next"
button on the form, the second servlet is invoked, and
it calls the bean's getNextName() and fetches the
required values; and commits the transaction.
Our problem is, when the user invokes the first
servlet, and then, chooses to remain idle for more
than 5 minutes, the transaction gets timed out, and
then, if we try to invoke the second servlet, it gives
a RollbackException in the getNextName().
This is because the org.jboss.tm.TxManager class has
got the timeout value hard-coded in it as :
START OF JBOSS SOURCE CODE-
/**
* Default timeout in milliseconds.
* Must be = 1000!
*/
long timeOut = 5*60*1000;
END OF JBOSS SOURCE CODE---
Because of this, we cannot let the user remain idle
for more than 5 minutes.
However, our application, which is a conversion
project from AS/400, needs to have the timeout set to
a higher limit as in the earlier AS/400 version of the
application.
Can we change this timeout value in the
org.jboss.tm.TxManager class, without affecting
anything else?
Thanks,
Sujith.
Additional info:
From the org.jboss.tm.TxCapsule class:
JBOSS SOURCE CODE---
/**
* Create a new TxCapsule.
*
* @param tm The transaction manager for this
transaction.
* @param timeout The timeout for this transaction
in milliseconds
* (timeouts are not yet
implemented).
*/
TxCapsule(TxManager tm, long timeout)
{
this(tm);
status = Status.STATUS_ACTIVE;
start = System.currentTimeMillis();
this.timeout =
TimeoutFactory.createTimeout(start+timeout, this);
branchXids = new HashMap();
}
