Also: Driven by client request the following changes have been made the the StdServerSessionSession/Pool in the ASF implementation: 1) 3 new elements have been added to jboss.xml | <LazyInitialization></LazyInitialization> | <RecycleIdleSessions></RecycleIdleSessions> | <IdleTimeOutMinutes></IdleTimeOutMinutes> | | LazyInitialization being set to true requires that the StdServerSessionPool be lazily constructed with only the minimum pool size being created on startup. RecycleIdleSesssion being set to true creates a JMS Reaper that functions in the same manner as our IdleRemover: removes idle JMS Sessions a configured interval (IdleTimeoutMinutes) As a result, the StdServerSessionPool functions in a similar manner to the InternalManagedConnection pool. A semaphore has be implemented to managed acquiring session. Idle sessions are recycled with a PoolFiller maintaining the minimum pool size in the case that the session count falls below the minimum. THis stuff is on a different branch at this point but my plan is to carry these features over to the JMS Inflow stuff as time permits.
