where to see max/min MDB instance

[leishen]

Attached is my jboss.xml for a MDB. I am trying to play with
various configuation to see how it works, among the things
you can configure, there are
15
5
and I believe that are used to config the instance numbers on the pool.

When I looked at the jmx-console for java:j2ee
jndiName=local/MyFirstMessageDrivenBean,plugin=pool,service=EJB

I saw the maxsize is 100, and no where to see minsize.
Am I looking at the correct place?

Thanks
Lei

Your configuration is for the session pool.
You are looking at the ejb pool.

The session pool configuration will be exposed on the container invoker
from 3.2.4RC1. To make changes take affect, you must restart delivery.

Adrian:

Thanks for the message. Couple follow on questions and want to make sure I understood the whole thing correctly:

1)
If I want to know how many concurrent messages that MDB can handle, which pool should I look, session pool or EJB pool?

2)
It is kind easy to guess what is EJB pool. What is exactly the definition of session pool? what is
the definition of the session here?
I am guess that it doesnot make sense to have
more instance in EJB pool than instances in session pool. Is that right?

Thanks
Lei

1) The session pool. You showed it before. They are ServerSessions that wrap
XASessions.

2) The EJB pool is largely irrevelent unless your MDBs are expensive to construct.
