User development, A new message was posted in the thread "MDB Pool size configuration": http://community.jboss.org/message/530861#530861 Author : Brad Warren Profile : http://community.jboss.org/people/bwarren Message: -------------------------------------------------------------- I'm looking for a definitive answer on configuring the pool size for an MDB.  I've seen several conflicting answers between forum posts and documentation, see http://community.jboss.org/thread/147300?tstart=30   Is it the @Pool annotation?  http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/...   {code}(a)Pool(value=PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX,maxSize=50,timeout=1800000){code}   Is it the @PoolClass annotation?   http://www.jboss.org/ejb3/docs/reference/build/reference/en/html/session-...   {code}@PoolClass (value=org.jboss.ejb3.StrictMaxPool.class, maxSize=50, timeout=1800000){code}   Is it the MaxPoolSize ActivationConfigProperty?   {code} @MessageDriven(     activationConfig={         ...         @ActivationConfigProperty(propertyName="MaxPoolSize",propertyValue="50")     } ) {code}   I've also seen a suggestion to change this section in ejb3-interceptors-aop.xml   {code:xml}      <annotation expr=&quot;!class((a)org.jboss.ejb3.annotation.Pool)&quot;&gt;          @org.jboss.ejb3.annotation.Pool (value="StrictMaxPool", maxSize=15, timeout=10000)       </annotation> {code}   But that applies to every MDB.   I've also looked at the message-driven-bean invoker-proxy-binding in standardjboss.xml and changing the MaximumSize, but that also applies to every MDB.   I've tried the @Pool annotation.  I see that MaxPoolSize is 50 in the jmx-console, but if I do a thread dump when there are many thousands of messages backed up in the queue, I only see 15 WorkManager threads processing messages.   So what do I need to do to get more than 15 messages processed at once?   I'm using JBoss 5.0.1.GA and JBoss Messaging 1.4 -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530861#530861
