Tomcat would not contain information on a Vendor's product. A quick Google search for "oracle ojdbc7 ucp-worker-thread" yields the following very relevant result: http://stackoverflow.com/questions/9671270/oracle-ucp-driver-and-tomcat- threads-failing-to-stop Also, searching for the OJDBC manual has a FAQ which mentions threads and their lifetimes: http://www.oracleimg.com/technetwork/articles/sql/jdbc-faq-090281.html > The threads are not shutting down and they stay alive when the web > service is shut down.

Oh, I believe you that they are piling up. Is there a particular reason you are using Oracle's connection pool rather than the one provided by the container (Tomcat)? Tomcat's pool won't leak like this one does. Then again, the Oracle driver itself might still leak, but it will be less leaky. It's possible that the driver needs to be loaded before the application in order to avoid pinning the ClassLoader into memory. That can be done with Tomcat's configuration, but I'd only recommend that you do this if nothing else is working. I'd still like to know that those other threads (e.g. Thread-0) are doin g. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlbdnygACgkQ9CaO5/Lv0PCClgCfUmDNGz68sT6beiMOwx2Pkewb UGcAoJNpSVJ8wagZRiGZMS9LxO3g0KY9 =qWGg -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
