Subject [jira] Updated: (GERONIMO-2090) Confirm that if version N is deployed, you can distribute version N+1 and later start it somehow
Date Sun, 16 Jul 2006 07:07:00 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-2090?page=all ]

Alan Cabrera updated GERONIMO-2090:
-----------------------------------

    Fix Version/s: 1.1.x
                       (was: 1.1.1)

Moving unassigned issues over to the 1.1.x pool where they can be worked on for the, in all
probability, 1.1.2 patch.

> Let's say you deploy foo/MyApp/1.1/war, to 10 identical servers.
> Now you have version 1.2 ready.
> It would be nice if you could distribute 1.2 to all 10 servers (while 1.1 is still running).
 Then you'd have to be able to run a command to essentially say "switch off 1.1 and switch
on 1.2" in one shot (perhaps using a sticky load balancer to upgrade part of the cluster and
let the rest of the cluster handle old sessions until they're finished).  This isn't precisely
a redeploy (the stuff is already distributed, whereas a redeploy expects to send the new files).
 More of a "cutover" command.
> I suspect there may be bugs in the console and/or tool that manifest if you have two
different versions of the same module installed simultaneously.  The deploy tool may also
not let you distribute a second version of the same module.  But we also need a new command
to do the cutover.
