Obviously, you can set up a validationQuery in the 2 MS SQL Server resources by just adding an appropriate query (e.g. "SELECT 1 FROM DUAL" or whatever is appropriate in MS SQL Server) to the <Resource> attributes. Were you hoping to get some other behavior than just what validationQuery already provides? FYI if you are using Tomcat's default connection pool, then you are using Apache commons-dbcp, whose configuration guide can be found here: http://commons.apache.org/dbcp/configuration.html That will explain all the configuration attributes you can use (right in the XML) and what they all do. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlEIAq0ACgkQ9CaO5/Lv0PBwvgCfd/QXbOkTEsCA4+dVG3GkhcYu dOQAn0lAOIdxaok55TJCE5pu7jb+aR4t =izRU -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
