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="!class((a)org.jboss.ejb3.annotation.Pool)">
@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
