Guys, I have an app that is using mdbs. The mdbs process messages and return a response, ultimately through networking protocols. They must response within a finite amount of time, which they do - but not on the first call, since this seems to be when the mdb is first created. Is there a way of preloadng the mdbs on app server start up and keeping them in memory regardless of usage? is this what @ActiveConfig minPoolSize=x will do? Thanks, Andy.
