mod_cluster-manager: disabling a worker / domain
------------------------------------------------
Key: MODCLUSTER-50
URL:
https://jira.jboss.org/jira/browse/MODCLUSTER-50
Project: mod_cluster
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Jean-Frederic Clere
In mod-jk, we had the ability to disable and/or stop a worker. Disabling a wroker W meant
that existing sessions would be served, but new sessions would not be created on W, until
W was enabled again.
I'd like to have the same capability in mod-cluster. It would be good to have
* this capability added to /mod_cluster-manager and possibly
* provide a script (in jboss/bin ?) which allows an admin to do the
same thing, e.g. "./disable-worker.sh node2" or "./disable-domain
D3"
The functionality should include
* Disabling a worker W
* Stopping a worker W. Note that we can achive this by shutting W
down, but 'stopping a worker' merely removes W from httpd's worker
list, but doesn't require a shutdown of W (W would also not
register with httpd at this point)
* Starting a worker W. The opposite of stopping W. Have W resume
registering with httpd
* Enabling a worker W. Allows for new sessions to be created on W
* Disabling / stopping / starting / enabling a domain D. Same as
above, but for all workers in a given domain D.
* It would be nice to be notified when all sessions in a disabled
domain have expired
