18.3. Pool Access

The pool is designed for concurrent usage.

Up to <max-pool-size/> threads can be inside the pool at the same time (or using connections from a pool).

Once this limit is reached, threads wait for the <blocking-timeout-seconds/> to use the pool before throwing a No Managed Connections Available exception. More information about this exception can be found at http://www.jboss.org/community/wiki/WhatDoesTheMessageNoManagedConnectionsAvailableMean.

You may need to use the <allocation-retry/> and <allocation-retry-wait-millis/> elements to have the pool retry to obtain a connection before throwing the exception.
