[Installation, Configuration & DEPLOYMENT] - Re: Re-deployment questions?

by dickson1888

Thanks for Allen's advice. I am new user for JBoss and still study to use it. My first step is to setup a simple environment that achieve all I need. Then, further step is HA (cluster, failover,...etc). I spent a little bit time to read about the cluster of JBoss. The documentation is not clear to show the steps to setup the clustering. I hope JBoss can have a simple clustering setup example steps by steps. If you have simple steps to setup simple clustering, please let me know. Thanks.

[JBoss Messaging] - Re: HeuristicMixedException: cause and remedy?

by kennardconsulting

Tim, Thanks. I have posted a message on the JCA forum. Please note I may not be the only one seeing this. This JIRA seems to indicate they see it intermittently too: https://jira.jboss.org/jira/browse/JBESB-2484 It says "JBoss Messaging sometimes causes a HeuristicMixedException to be raised by the transaction manager during commit. Once this happens the associated session would appear to be destabilised in that subsequent use does not appear possible... The exceptions are always generated with the same session id which would suggest that there is an underlying issue in the JBoss Messaging codebase. We need to handle this until the issue is resolved within JBM." Their JIRA is more concerned with working around the problem, but it was only opened in March 2009. Perhaps you could ask the ESB guys about it?

[JCA/JBoss] - HeuristicMixedException: cause and remedy?

by kennardconsulting

Hi guys, The JBoss Messaging guys suggested I post here (original thread here http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241134#4241134). I'm having a hard time finding good documentation on javax.transaction.HeuristicMixedException. JBoss Messaging (and the old JBoss MQ) seems to throw this exception intermittently while processing large volumes of messages in a batch (say, 2000 messages over 3 cluster nodes): javax.transaction.HeuristicMixedException | at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate | (TransactionImple.java:1431) | at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction | .java:137) | at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDeleg | ate.java:75) | at org.jboss.resource.adapter.jms.inflow.JmsServerSession$XATransactionDemarcationStrategy.e | nd(JmsServerSession.java:657) | at org.jboss.resource.adapter.jms.inflow.JmsServerSession.run(JmsServerSession.java:243) | at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:205) | at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:260) | at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) | at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) | at java.lang.Thread.run(Thread.java:619) The worst thing is, once the exception is thrown, that node is effectively dead. No more JMS messages get processed. My app has multiple queues, but once one queue on the node fails (say, the e-mail queue) then all queues stop working (say, the reports queues): they all report HeuristicMixedException whenever a message is sent to them. Can anybody suggest why this error happens, and whether there is some setting to automatically recover from it? If I manually restart the node it works fine.

[JBoss Messaging] - Clusted FailOver doesn't seem to work correctly with Bridge

by artp

I have a cluster that I'll call cluster A that has a Bridge that moves messages from a Cluster A queue to another cluster's(Cluster B) queue. Cluster B contains two nodes(B0,B1). Initially, when i start all the nodes up all is well, messages are moved from Cluster A to one node(ie B0) in Cluster B. When i take down B0, i get failover messages, on B1, saying that fail over is happening and it's completed. Natually, i'd expect further messages from Cluster A to be processed by B1. Sometimes FailOver works to B1, but most of the time it doesn't. When it doesn't I see the MessageCount and DeliveryCount grow higher has i send more messages from Cluster A. It looks as if the Bridge is doing it's job since i can see the messagecount from the jmx console. FailOver appears to be causing something to go wrong once messages get to B1. From that point on messages are stuck on B1. To get the messages out of the stuck state i have to bring nodes up and down(ie. bring B0 up then take down B1). Eventually, the FailOver kicks in and one Node proceses the messages. Once that happens, messages are processed. Is there something i'm missing? Environment: jboss 5.1, JBM 1.4.4 src, I modified JMSRemoteConnection to compile against Remoting 2.5.1, so we could have the Bridge fixes, etc. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241305#4241305 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241305

[Clustering/JBoss] - Re: HASingletonDeployer ERROR upon secondary server startup

by RichardTaylor

Shall I write up a JIRA ticket for this issue so that it shows up on the appropriate "radars"? We're getting ready to deploy to production with 5.1.0 so we're interested in tracking this topic.

[JBoss jBPM] - Re: Search function of jBPM forum messed up?

by kukeltje

I have not noticed it, but some searches I' ve tried indeed yield nothing. On all forums... A workaround is to use google and add 'site:www.jboss.org' to the query View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241300#4241300 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241300

[JBoss Tools (users)] - Re: High CPU on JSF auto-complete

by jboden

Thanks Max for your help, I took your idea and stated a new project with one bean and one JSF page. As expected, it worked quickly. I then copied my 25 beans and 25 jsf pages, and added faces-config.xml entries. It then went back to 100% cpu. Not sure if that's a valid test with all of the compile error present from just dropping in class files without the spring configs and related classes. As far as screen shot, I simply hit Ctrl-Space and everything freezes. At this point I think I'll have to punt and assume it's something in my project. If anyone has thoughts on what might do that, I appreciate your thoughts. Too many public methods, public or static vars in the beans? Anything Spring-related? I'm including persistence beans into my faces beans as properties in faces-config.xml. <property-name> and . The one JSF bean that does respond quickly does not have these references, but it's also newly created. Not sure if that would matter or not. Any thoughts would be great and we'll just live with it until future releases or faster hardware. :-) Thanks! It sounds like it's specific to my project.
