I am very confused by the internal behavior of persistent manager of jboss
messaging with ms sql server.
I use event tracer of ms sql server to capture sql statements sent out from one
jms message comes into jms queue to consumed by consumer.
The following sql statements shows one jms message
We are now using JBM 1.4.0.SP3, and we just use a queue with one message
producer and one message consumer, never use topic.

Afterward we setted up another test, this time we setted the parameter to ten
minutes,
and we setted the FullSize parameter, PageSize parameter, DownCacheSize
parameter of the queue to be tested
to 3355444, 1, and 1, and the messages we sended in this test were all
NON_PERSISTENT
the duration parameter to ten minutes

Hi,
I am now attempting to use JBM as a JMS Server on my application.
I did a performance test on it using the JBossJMSNewPerformanceBenchmark
framework,
but the result was so difference from the performance result that we saw on the
development wiki.
My test environment and executors setup
As you said, Database that persistent manager processes is bottleneck. Is there
any method can improve performance of the traffic between jms queue and
persistent db? Exactly, we tried to use batch mode for persistent manager. But
I don't find any option to alternate the batch size. Finally, I
Another question :
How can I turn off the persistent while sending and receiving messages ? That
means all the messages sended to the queues are just store in memory.
regardless PERSISTENT message or NON_PERSISTENT message.

En, could you please tell me how JBM determine client and server are in the
same VM ?
You know, in a Servlet we use JNDI as follow :
Context ctx = new InitialContext();
QueueConnectionFactory factory = (QueueConnectionFactory)
ctx.lookup(java:/ConnectionFactory);
and we don't use the JNDI
I am now using JBoss Messaging as a JMS server in my application and I don't
use any Cluster feature now and this application is deployed on JBoss AS
4.2.2.GA. In my application I use JMS API to send messages and receive messages
in a Servlet, that means the JMS client and JMS server are in the
