2012-02-06 Thread Domenico Briganti 
Hi Fernando, 
open HTTP/AJP il the last step that tomcat do when it starts. Why don't
you put your initializzations on webapp's context initialize and wait
the ready of your resource that?

There is a recent thread on this topic, see
http://old.nabble.com/Best-practices-for-deployment-on-cluster-environment-td29532493.html

If you need service continuity, you have to use at least 2 Tomcat
instances

Thank Pid, Yes, I know that. But I have 24 Apache server and more than
200 worker configured. If I can, I prefer to not manage mod_jk too. 
I will let you know if my system works,

Re: Best practices for deployment on cluster environment

2010-08-27 Thread Domenico Briganti 
I've read many response to this thread, but when you redeploy in an
enterprise environment (many httpd+mod_jk -> 4 tomcat server -> a db)
independently if use shared or not appBase, manual or scripted deployer,
with or without tomcat manager, you return to your client at 404 or
worst a 503 when a request reach the tomcat. And for my application it's
not permitted

This is what I think I can do:
Environment (24 Apache+mod_jk -> 4 tomcat server)
mod_jk with ping_mode=A and prepost_timeout=1000
to redeploy a wabapp:
For each tomcat server:
   Connect to JMX MBean and stop AJP connector.
   Wait the end of all APJ RequestProcessor.
   Redeploy webapp with tomcat manager.
   Restart tomcat.
   Wait for 60 sec (The default maintenance of mod_jk).
end.

How about this?

Regards,
Domenico
