rolling deployments with tomcat clustering
Hello,
I have a tomcat 7 cluster which I want to do rolling deployments.
I am using FarmDeployer. I am wondering, what is the default behavior of
FarmDeployer, does it undeploy and deploy the new app all at once?
Is there any way to modify this behavior to do it serially?
Thanks,
z

Yes, it will have to be dynamically detected somehow. A real chore.

Note that any JMX monitoring you are doing will likely have to change
due to the new "name" of the context.

Try versioning your war files.
myapp##v1.0.0.war
myapp##v1.0.1.war
This feature is called 'parallel deployment'.
You can use JMX to monitor the activeCount of sessions of the older
version and also to undeploy it when that number reaches zero.
