No, I am not saying that. I am saying that the connections, being returned to the pool on connection.close(), remain open as long as they are not garbage. When a context is reloaded, the previous context hangs around for a while. That context holds reference(s) to the pool, which in turn holds reference(s) to open connections. Once the context is gc'd, then the cascade effect is to close the connections.
Bouncing the entire tomcat server will always close all the connections, because all contexts are shut down and garbage collected. Tim P.s. See this: http://marc.theaimsgroup.com/?l=tomcat-user&m=114001512903342&w=2 (which still has no answer, BTW. Anyone have one? I'd be happy enough to be able to manually shut down the pool on my ServletContextListener.contextDestroyed()) -----Original Message----- From: Edward Quick [mailto:[EMAIL PROTECTED] Sent: Friday, March 10, 2006 7:50 AM To: users@tomcat.apache.org Subject: RE: Tomcat jdbc settings Thanks Tim. I have also noticed that bouncing the tomcat clears the connections. So are you saying java's garbage collection will clear the old connections out? Does this mean my settings below are redundant?
