Is there a way to verify that the > cluster is working? What do you define as a "cluster"? Are you just load-balancing between machines that aren't tied to each other in any way? Are you attempting to use distributable sessions? What component is "clusterizing" these machines? Do you have an lb out front, or Apache httpd + mod_jk/mod_proxy? These details are useful in helping you. > I can see no message exchange. is there a way (even > some jsp code) to ensure that the cluster is working and the number of > nodes joining it? You may be able to verify that sessions are being distributed properly by modifying your own JSESSIONID cookie (or simply running with cookies disabled and then manually changing the 'jsessionid' parameter in the URL in order to force connection to a particular backend. Again, this depends entirely upon your lb strategy (which we don't know). > Furthermore...is there some debugging tool to see the cluster status? Logs certainly help. How about providing your startup log from catalina.out? Also, make sure that you have logging.properties set up in a sane way, and that you can get debugging output from at least one component. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxAuV8ACgkQ9CaO5/Lv0PBOnQCcCaOcC9gmtmixIUFYAzVCYvUy 3u4AnjsorOZJbbZEO4GGFKshOr94q7JH =Qobh -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
