Hello Mladen,
Great, now my cluster hot standby works as aspected. Thanks for your quick help!
Current support of redirect is enough for me.
<http://dict.leo.org/se?lp=ende&p=/Mn4k.&search=enough>The domain redirect use case to startup very save a next software generation
is working with the existing domain concept.
You have two tomcat cluster domains. Two Apaches and three tomcat instances at every cluster domain.
worker.nodeA01.domain=A0 worker.nodeA02.domain=A0 worker.nodeA03.domain=A0 worker.nodeB01.domain=B0 worker.nodeB02.domain=B0 worker.nodeB03.domain=B0 worker.list=lb,status worker.lb.balance_workers=nodeA01,nodeA02,nodeA03,nodeB01,nodeB02,nodeB03 worker.lb.type=lb worker.status.type=status
Now you want start a new software generation under high load
Start the new Instance A1x, B1x change the workers.properties at apache A and B gracefull restart the apaches.
worker.nodeA01.domain=A0 worker.nodeA01.disabled=True worker.nodeA02.domain=A0 worker.nodeA02.disabled=True worker.nodeA03.domain=A0 worker.nodeA03.disabled=True worker.nodeB01.domain=B0 worker.nodeB01.disabled=True worker.nodeB02.domain=B0 worker.nodeB02.disabled=True worker.nodeB03.domain=B0 worker.nodeB03.disabled=True worker.nodeA11.domain=A1 worker.nodeA12.domain=A1 worker.nodeA13.domain=A1 worker.nodeB11.domain=B1 worker.nodeB12.domain=B1 worker.nodeB13.domain=B1 worker.list=lb,status worker.lb.balance_workers=nodeA11,nodeA12,nodeA13,nodeB11,nodeB12,nodeB13,nodeA01,nodeA02,nodeA03,nodeB01,nodeB02,nodeB03 worker.lb.type=lb worker.status.type=status
Old Session A0x, B0x working very well for old existing session and replicated backup.
All new sessions goes to A1x,B1x nodes
After a some times, the admin can drop the old nodes (A0x, B0x) with zero sessions active and than remove the
A0x and B0x workers.
How can I force a autoreloading with update the workers.properties, without gracefull restart the apache?
Thanks very much, Peter

You will still need the redirect for hot-standby to work. It's just like for workers, except that instead worker name the domain is used, so you can have multiple failover boxes.
Sorry, It won't failover to domain, so:
worker.node1.domain=A worker.node1.redirect=node3
worker.node2.domain=A worker.node2.redirect=node3
worker.node3.domain=A worker.node3.disabled=True
I'll see if and how a failover redirection for hot standby can be made to a group of workers. Not sure if this will have any real world usage, but it can be made. Convince me why would someone need 5 boxes not doing anything just in case. I mean, a single one should be enough ;).
Mladen.
