In the future, put all the information a reader needs to understand your question in a single post. Otherwise, you run the risk of lazy people (like me) not bothering to go hunting for your other post just to get the back-story. (It also irritates archive-hunters). So, I'm proceeding with no existing information, other than you probably have a load-balanced Tomcat configuration. > What I mean is if I have just 2-3 nodes, while we are performing a > new webapp deployment, we would like that users continue to be > served using the non-updated webapps of course, transparently for > them and with no downtimes. Are you using sticky sessions and does the load-balancer stick them properly? If so, enable Tomcat's parallel deployment and do your deployments "properly" according to those rules. You can update any server at any time you want. Don't forget to undeploy the old version(s) after users sessions expire. You could also couple that with the "farm web deployer" which I myself have never used. > I have thought about it and I have thought of having two tomcats > in each server node that are synced and a second failover Tomcat > in server1 which will take all requests while the main Tomcat in > server1 is being updated. > > Does it make sense? You could do that, but I think it's just more work with little benefit. - -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/ iQIcBAEBCAAGBQJRXcw0AAoJEBzwKT+lPKRYXUoP/35bJ+5/Tj2CaV5mW3PyDFVM mZfWb/BgCT/yCHSKBgy3vhEgZnhUdMiJm2lO1lsTcYb0hYmd2Otjj0MArgBjmdJ1 6xuV8WBMzLPwH0mlBT8QqDz8R5yDu8YsAGPytE3f/tGl5hz2KJ8C0mVXIh9MZ2o6 /WkyXp3e7uXi8xq6+os2ZHoiYyO7ZAetNVxcJ+wEwMHkaHo64udBmj5rAb/6lzez 8eMW71QfegQLE7yzfeoDcEFUeQP2Quve7jcRMmiaHhmW3eemKf3BajTXCuWYchHQ tkrjTTkHytQzsrqqDURXSxXFgaOT/+AiSAcwTr3gfVCdjxIIY7lW9hpzFbmEZ/Os 4bMcrE4SeqsrjlUm8hdP/oIA5vPw/l2IASIZB5EYL1dAPXGuGUwNfm8qO9jGojXy DBo3/Ju0qLTE2KKiJULfA293OsM7jqB7DfNI21a+z9vAvnLnkpduBMLPqB036god eArccFyXGEeNLVvyDIC9VtksfBNSudMaH7ZMXnmCpnCN7WAml2MiWYNjPyI+o+Tv 8eWBseEX8lzlNXt0vgtUqhIuHKCWvgU1mlY1lSe7ctiSqW2jZ7PaXEhJxSJnDgZm 1YorWMeg/z6c3Q5dtHRx374LaE1bMScrtRK+/G+etqV1i/HB365KpdyIPGm5DeqI 7XVPGsY0sWGJHtQ4Zzvo =mM3l -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
