You cannot lower the maximum below the value of steady-pool-size. > If you try to do this, it reports an error and won't let you proceed.

The pool is creating 8 connections because that’s what the minimum is set to. Testing with a delay in your web service code between the connection acquisition and close calls - as Robert T already did - will show the pool size not growing beyond 8 until there are more than 8 concurrent requests being processed. > This is clearly stated by the monitoring report, and you can’t disagree with > that. The report only shows that 8 connections have been created; there is no indication in the report of anything else. > I have considered upgrading to a newer version of Glassfish, but this would > be another project that I'm not prepared to undertake right now. But you apparently are prepared to handle all the security risks of running a 11-year old server exposed to the internet. Bad tradeoff. - Chuck --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org<mailto:users-unsubscr...@tomcat.apache.org> For additional commands, e-mail: users-h...@tomcat.apache.org<mailto:users-h...@tomcat.apache.org>
