[JBoss-user] [Messaging, JMS JBossMQ] - Re: Why serialize object message if using jvm invocation lay
I get it. That would probably be asking too much of the clients - knowing that they can't modify the object. Maybe another way to optimize it could be calling clone() if Cloneable is implemented, or else take the hit with the current impl - (de)serialization?

[JBoss-user] [Messaging, JMS JBossMQ] - Can't initialize MessageCounterHistoryDayLimit to zero
While analyzing the performance of my app, which runs on JBoss 3.2.5, I noticed significant cpu usage eaten up by my JMS queue's message history counter. I figured I could easily disable this by setting the MessageCounterHistoryDayLimit to zero, as show in the descriptor below. This resulted in a NullPointerException at startup caused by the jmx config service calling a setter on the underlying queue object before it was instantiated. Is there another way that I should disable this count history feature? depends optional-attribute-name=DestinationManagerjboss.mq:service=DestinationManager 0 true View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3852081#3852081 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3852081 --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Can't initialize MessageCounterHistoryDayLimit to zero
Well, that didn't work either. Basically, my queue config contains an 'attribute' element with the 'name' attribute set to 'MessageCounterHistoryDayLimit' and the element body is '0'.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Can't initialize MessageCounterHistoryDayLimit to zero
Thanks Adrian. I will look at the code and see if I can figure out where to make the fix. In the meantime, is there any workaround you can think of to disable this message counter history feature at deployment time?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Can't initialize MessageCounterHistoryDayLimit to zero
Adrian - To answer your question as to why the message counter is taking up so much cpu... I've been profiling one particular thread in my application which has popped up on my radar as a bottleneck. The thread basically receives requests via a tcp socket using a proprietary protocol. The request is wrapped up in a JMS message and enqueued to be processed by an MDBean. After focusing on this thread with a cpu profiler, I see that approximately 8% of its cpu usage is spent invoking MessageCounter.updateHistory. Drilling down one more level, I see that the main culprits are 2% in Calendar.getTime, 2% in the constructor for GregorianCalendar, 1.5% in MessageCounter$DayCounter.updateDayCounter and .5% in MessageCounter$DayCounter.getDate().

[JBoss-user] [Messaging, JMS JBossMQ] - Why startTx commit if MDB transaction=NotSupported?
I'm looking at my MDB performance using a cpu profiler. I see quite a few calls being made pertaining to transactions (e.g. SpyXAResource.Manager.startTx, SpyXAResource.commit, etc.). I'm confused because my MDB is deployed to be non-transactional. These invocations don't take up a whole lot of cpu, but I'm trying to trim off every unnecessary tick possible, as my CPU is pinned at 100%. Thanks.

[JBoss-user] [Messaging, JMS JBossMQ] - Why serialize object message if using jvm invocation layer?
I've been doing performance analysis on my application which relies heavily on JMS enqueuing and MDB request processing. I use the jvm-il-service for optimum performance. One thing I see is that a lot of time is spent serializing and deserializing my message objects (I'm using ObjectMessage). I'm considering changing to MapMessage to avoid this hit, but I was curious if the developers considered special treatment of ObjectMessages when the JMV IL is being used?

[JBoss-user] [Messaging, JMS JBossMQ] - jbossmq writes transaction to database even for non-transact
I've got a MDB with the trans-attribute set to 'Supports.' Some database reads and writes are performed within the onMessage method. I'm running with p6spy, which shows me all SQL statements executed by the application. This shows that jbossmq issues 3 additional database writes every time onMessage is invoked. This is performance problem for me. I don't understand why its even executing these transaction-related statements when my bean isn't even transactional. Could someone please help me make whatever config changes are necessary to disable this behavior. Thanks in advance. The 3 SQL statements are: INSERT INTO JMS_TRANSACTIONS (TXID) values(?) DELETE FROM JMS_MESSAGES WHERE TXID=? AND TXOP=? DELETE FROM JMS_TRANSACTIONS WHERE TXID = ?
