"WebSphere MQ issue"

--------------------------------------------------------------
Hi,
I'm running a web app in JBoss AS 5.1.0 with WebSphere MQ 7 configured as a JCA
resource. The application works well pushing/popping messages on and off the queues.
Recently during some load testing we've noticed two things that has us concerned. The
first is that the "open input count" on the MQ queues continues to grow and so
do the number of TCP connections to WSMQ.
I did some research and found that the MQ Queue Open Input Count "shows the number of
open input handles, that is the total handles open for input on this queue. This gives you
an idea on the number of applications that are currently connected to the queue to put
messages on the queue". In our test, the count rose to 125 in 20 hours of load
testing. The number of connections to WSMQ rose to 27 (according to netstat).
There is concern that over time these counts and connections will continue to grow.
Should there be a concern here? Is there some configuration that can control this
behavior?
BTW...the production system is running on a different application server and queue open
input count remains low 1 or 2.

Two options:
1. Look through the TRACE logging for the JCA container
2. See if the problem is the same on JBoss Application Server 7.0.0.Alpha
The 3rd option is of course to open a support ticket on the issue.

TRACE logging didn't reveal much. I did notice that there is a newer
"wmq.jmsra.rar" file than the one deployed in JBoss 5.1.0. The
"wmq.jmsra.rar" file is 3 months newer 8/13/2009 from WSMQ 7.
We are going to rerun the load test and I'll report back.

Ok, well I believe the problem has been resolved. Apparently, using the
"wmq.jmsra.rar" that came in the WSMQ 7 installed has corrected the problem with
queue "open input count" and number of connections. We ran another overnight
test and the queue "open input count" never exceeded 6 with 4-6 connections to
WSMQ.

Good. Feel free to try with the IronJacamar 1.0.0.Beta4 release too.

Hi Rod! Ihave similar configuration: jboss 5.1.0, wmq.jmsra.rar 7 and WSMQ 7. I configured
one connection factory in wmq.jmsra-ds.xml. I use it to send messages to ws mq queue (it
works perfectly). Recently I tried to receive messages within my MDBs. It requires
configuring inbound messaging and I stacked with samples based on jboss 5.0 and ws mq 6
which are not apropriate for jboss 5.1.0 and ws mq 7.
Please can you describe me way you receive messages from mq - and if you do it in inbound
manner can you post samples of your descriptors?
Thank you very much!

Below is the configuration that my app is using. There's more information there than
you need. I had to "clean" it somewhat before posting so hopefully I didn't
make any mistakes. I use token replacement {$...} with JVM properties in the jboss.xml so
that I don't have to hard code WSMQ configuration when deploying to different
environments.
