[JBoss-user] [Messaging, JMS JBossMQ] - Re: Are JMS messages cached?
We know that, but unfortunately you decided to switch from tomcat 4.x to tomcat 5 which makes 3.2.4/5 a new major release and not a minor release or patch. The customer would have to start their whole test cycle again, which would move the live date to next year, which would cost us more than $20. If that happens I could never convince my superior management that JBoss is a trustworthy Applcation Server and it would definitely disappear from our suggested platform list. So you see, all I am trying is to keep you in the game for our future projects...

and deleting the messages is only fighting a symptom anyway. Those messages should never appear in the database because they were already delivered before the database comes online again and there are no durable subscribers.

That is not correct. It is part of the design of the way the jdbc pm works. Non persistent messages added to store via the cache don't survive a restart. The cache does not fail just because it couldn't remove the persistent copy at acknowledgement time. It will let the restart tidy it up. The problem in earlier versions was that it was issuing an invalid sql statement | delete from jms_messages where txop='T' and txid=null | which some databases allow, but Oracle interprets correctly. It should have been | delete from jms_messages where txop='T' and txid IS null | It was something I fixed a while ago, but the code had regressed. Since the txid being null is irrelevent anyway, later versions do | delete from jms_messages where txop='T' | View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3852077#3852077 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3852077 --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Are JMS messages cached?
a quick update on this issue. According to our investigations the problem was the result of probably two bugs in Jboss. If the database is not available and the cache limit is reached, the messages are not deleted from the cache after delivery (you can see the the counter going up in the JMX console all the time). When the database is up again JBoss is writing all these messages to the database according to its cache configuration. Because the messages are already delivered these entries are never pickud up again and stay in the database. This in combination with the message cleanup bug on Jboss startup can lead to a unique constraint violation if new messages are written. It might be worth mentioning that the JMS cache configuration was too low given the used hardware, but still the messages should be removed from the cache after delivery. As a solution for now we increased the cache size and implemented a startup services that is cleaning the T entries from the JMS Messages table.

Durable subscriptions persist messages by default (unless you explicitly send non persistent messages). The T messages are non persistent messages that don't fit into memory. They are moved to disk to free up memory for something else when memory becomes full. Here is one my favourite links: http://www.jboss.org/wiki/Wiki.jsp?page=MessageSoftening Aren't you an IONA customer? It seems strange that you would be posting in the forums where there is no guaranteed service level (witness the 5 days delay in answering your original question) when you have access to support where you can get a guaranteed response?

My comment about the messages being sent to a temporary topic is actually not true. I mis-interpreted the T in the TXOP column. It only means they are inserted by the message cache, right? I still do not know how JBossMQ works when the database is down. I would expect to get an exception immediately, but it seems that JBossMQ is holding the messages in the cache and when the database comes back online it seems that the messages are then inserted using the CacheStore without being consumed. Any ideas, hints?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Are JMS messages cached?
Getting a little bit confused. My previous post was not right, I think. The destination for the entries in the JMS table is something like TOPIC.ErrorTopic.ID:3.-2147483648 This syntax with the ID is used for temporary topics, right? So, next guess: For some reason on the customer site the topics are temporary topics (nothing in the startup log is indicating that though). When the database is down, the service that runs and executes methods on our J2EE application is producing errors which we catch and send to JMS for logging purposes. The amount of errors exceeds the HighMemoryMark and as a result some of these messages are persisted when the database comes back online, but are not consumed (or at least not removed from the database). So our original problem seems to be the fact that the topics are temporary topics. We don't have any temp topics on our test systems and the startup output from the customer site looks fine, too: The topics/queues are bound 10:36:59,061 INFO [AdminTopic] Bound to JNDI name: topic/efpAdminTopic 10:36:59,061 INFO [AdminTopic] Started jboss.mq.destination:service=Topic,name=AdminTopic 10:36:59,064 INFO [ErrorTopic] Bound to JNDI name: topic/efpErrorTopic 10:36:59,064 INFO [ErrorTopic] Started jboss.mq.destination:service=Topic,name=ErrorTopic 10:36:59,066 INFO [AuditTopic] Bound to JNDI name: topic/efpAuditTopic 10:36:59,067 INFO [AuditTopic] Started jboss.mq.destination:service=Topic,name=AuditTopic 10:36:59,076 INFO [ActiveActivityQueue] Bound to JNDI name: queue/efpActiveActivityQueue 10:36:59,077 INFO [ActiveActivityQueue] Started jboss.mq.destination:service=Queue,name=ActiveActivityQueue and the MDBs are deployed without any warnings about non-existing destinations or created temporary destinations 10:37:36,479 INFO [JMSContainerInvoker] Started jboss.j2ee:binding=message-driven-bean,jndiName=local/SysAuditLogger,plugin=invoker,service=EJB 10:37:36,479 INFO [MessageDrivenInstancePool] Started jboss.j2ee:jndiName=local/SysAuditLogger,plugin=pool,service=EJB 10:37:36,479 INFO [MessageDrivenContainer] Started jboss.j2ee:jndiName=local/SysAuditLogger,service=EJB 10:37:36,516 INFO [DLQHandler] Started null 10:37:36,516 INFO [JMSContainerInvoker] Started jboss.j2ee:binding=message-driven-bean,jndiName=local/HistAuditLogger,plugin=invoker,service=EJB 10:37:36,517 INFO [MessageDrivenInstancePool] Started jboss.j2ee:jndiName=local/HistAuditLogger,plugin=pool,service=EJB 10:37:36,517 INFO [MessageDrivenContainer] Started jboss.j2ee:jndiName=local/HistAuditLogger,service=EJB 10:37:36,541 INFO [DLQHandler] Started null 10:37:36,541 INFO [JMSContainerInvoker] Started jboss.j2ee:binding=message-driven-bean,jndiName=local/ErrorLogger,plugin=invoker,service=EJB 10:37:36,542 INFO [MessageDrivenInstancePool] Started jboss.j2ee:jndiName=local/ErrorLogger,plugin=pool,service=EJB 10:37:36,542 INFO [MessageDrivenContainer] Started jboss.j2ee:jndiName=local/ErrorLogger,service=EJB 10:37:36,576 INFO [DLQHandler] Started null 10:37:36,577 INFO [JMSContainerInvoker] Started jboss.j2ee:binding=message-driven-bean,jndiName=local/BFAuditLogger,plugin=invoker,service=EJB 10:37:36,577 INFO [MessageDrivenInstancePool] Started jboss.j2ee:jndiName=local/BFAuditLogger,plugin=pool,service=EJB 10:37:36,578 INFO [MessageDrivenContainer] Started jboss.j2ee:jndiName=local/BFAuditLogger,service=EJB 10:37:36,615 INFO [DLQHandler] Started null 10:37:36,616 INFO [JMSContainerInvoker] Started jboss.j2ee:binding=message-driven-bean,jndiName=local/ActiveActivity,plugin=invoker,service=EJB 10:37:36,616 INFO [MessageDrivenInstancePool] Started jboss.j2ee:jndiName=local/ActiveActivity,plugin=pool,service=EJB 10:37:36,617 INFO [MessageDrivenContainer] Started jboss.j2ee:jndiName=local/ActiveActivity,service=EJB View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3850636#3850636 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3850636 --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
