I am MQ admin and not WAS. Please correct me if my understand is wrong.
I have JMS application running in WAS connecting to MQ. Some use client connection and some uses server. I understand that WAS maintain a pool of MQ connection for JMS clients. If my JMS application is using server connection, does it also get the connection from the pool ?

The reason I asked is we had a server crash and some application which uses server connection are reporting problem that they cannot reconnect. unfortunately some one has also cleared all the error logs. We have to work with our WAS admin to figure out if we need more connections.

As a rule of thumb
(2 times the max configured number of mdb instances) +1
... add up for each mdb
add on top of that a percentage for growth...

Have fun

Thanks for the ROT.
The reason why we need to know if JMS app using server connection to MQ is also using the pool is because during the recovery of the last outage we were told that some JMS app which using server connect cannot reconnect because there was no more free connection in the pool. Since all error logs are gone, we cannot prove that. But what we want is all the server connected Apps get the connection first before the client connected app. if they both use the same pool. Of course, there is no concern if server connected Apps are not using the pool .

Use runmqsc (or other suitable admin tool) to display the connections and channel status (for svrconn type channels). This will give you an idea of method being used (server binding or client) and the number of conns from WAS.
