Throttle creation of new connections ------------------------------------ Key: JBAS-3033 URL: http://jira.jboss.com/jira/browse/JBAS-3033 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: JCA service Reporter: Elias Ross When a pooled connection is not available, the connection pool creates an additional connection with no waiting, up to the maximum allowed size. What tends to happen with many worker threads is the DB pool grows very quickly. It would be nice to have a settable property with the following behavior: 0. if there is an available connection, return it 1. poll() for N seconds for a recently returned connection, if one arrives in N seconds, return it 2. else, create a new connection For JMS connections, this would be useful for keeping the server from creating the maximum number of MDB right away and ballooning memory. Additionally (and perhaps as a different bug), the BasicThreadPool should have this sort of property as well.
