[Messaging, JMS & JBossMQ] - Re: Automatic topic creation & deletion through EJBSessionBe

by adrian＠jboss.org

Why do you need a whole topic for each user? Surely you can use one topic with subscriptions based on some kind of user-id filter in the message? NonDurable Topic subscriptions are automatically deleted when the connection is closed or fails. Anyway this is a consulting question not a technical question. I'm not going to design your application for you. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130826#4130826 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4130826

[Microcontainer] - POJO thread safety

by david.lloyd＠jboss.com

If I have a POJO that (for example) represents a service that has a few properties that will be injected, what thread-safety precautions must I take? Will the POJO be instantiated, configured, and started/stopped all from the same thread? If not, what guarantees are made with respect to synchronization externally?

[Messaging, JMS & JBossMQ] - Re: JMSXDeliveryCount with GenericDLQHandler

by adrian＠jboss.org

"svadu" wrote : | Can someone give me a clue on the problem (I hope I described the problem more or less accurately)? | JMSXDeliveryCount is a property set by the JMS provider (Tibco) not JBoss. We just use it to determine number of redeliveries when it exists (it is optional). Perhaps it is a property Tibco doesn't support, but the message originated in some other system that does set the property. i.e. Tibco just copied it? anonymous wrote : | Do I need to rely (woudl require even more vendor specific configuration) on the external JMS server (Tibco in this case) to handle redelivery counts? | No idea. But I'd imagine Tibco has internal support for DLQs or some other poisened message handler?. So you probably don't need to configure a DLQ handler in JBoss at all? * Set the activation-config-property useDLQ=false * Configure a DLQ (or whatever mechanism they have) for your queue/topic in Tibco. The only reason the DLQ handler exists in the MDB is because JBossMQ doesn't support them internally. Most other JMS providers do support them inside the server.

by dd_la_frime

Hello, I need to know if JBM runs with informix database as there is no informix-persistence-service.xml file ? If JBM can run with such a database could you please give me the xml file for the SQL schema to be created. Cheers. Christophe.

[Clustering/JBoss] - Re: Potential issue with JGroups using JBoss 3.2.7 and Java

by ross.nelson＠saic.com

Apologies for the strange text that appeared above, hopefully this notepad version works better. Java version is 1.4.2_09b05 (cut off from title) Hi there, first post on the site, I currently have a live application (GT-X7 running on JBoss 3.2.7) which makes use of JGroups for clustering. We have 5 "kernels" involved in the group and both today and yesterday we have experienced a "hang" on the 1st kernel which is the originator of the group several hours after startup. This hang renders the kernel completely inaccessible, all logging is halted (Garbage Collection halted in the middle of spooling a row), it's as if the kernel has paused itself waiting for something to happen. It would appear in the meantime that the other 4 kernels continue working away. On the first occasion we did not manage to the get the kill -QUIT to output anything before we restarted. Fortunately today we managed to get the kill -QUIT to go through and I will enclose the output below. The reason I come to JGroups is the item at "waiting" on the dump appears to be part of the JGroups setup. - "MessageDispatcher up processing thread" (from google searching) On both occasions I have observed that around 1 minute before the "hung" kernel occurs, another member of the cluster is suspected, removed and then quickly re-introduced to the cluster, from google searching I did see a bit about "simultaneous" kernel exclusion causing a problem, however this doesn't appear "simultaneous". Thanks in advance for any assistance or even advice on areas to focus on - I'm a bit between JVM (Garbage Collection) and JGroups on this one, will be posting questions both here and on the sun site. I'll post the dump first and then snippets from the STD Out Logs which contain the JGroups comings and goings ....

[Messaging, JMS & JBossMQ] - Re: Error Caught unusual exception in nackMessage

by adrian＠jboss.org

It says the jms server couldn't update the redelivered status of the persistent message in the database because of some Oracle database error you don't show in your post.
