There is one pitfall: If you changed the database shema, EOModel and use
ERXMigration (what have I done without?)
Yes, that can be a problem. Not bad if you are only adding columns, but if removed
columns or adding constraints, when people in the "old" instances save data, it
might blow at the database level.
Adding colums might be also a problem if you add default values via
awakeFromInsertion().

oh!
is that what bounce does?
well then!
so,
1 press bounce
2 deploy new files
2 is press bounce, 1 is deploy new files
3 wait for new instances to come up
The bounce action will start any inactive instances. So you have one running instance and one idle,
and when you "bounce" the already running instance go under "refuse new
sessions" mode (so current users can finish their work) and the idle instance kicks off with
the new code.
so, new instances have the new files and existing instance sessions reliably
run on old files?
Yes, the new instances have to start from another bundle. So say "old" instances runs on
/opt/MyApp.woa.20110101 and the "new" instances runs on /opt/MyApp.woa.20110504

Hi,
I have a question regarding the deploy. Is it possible to redeploy an
application when the application is running, or I need to shutdown every
instance, deploy the application and restart every instance?
You will have classpath issues when doing that. It's better to use the "Bounce" feature of Monitor,
which put the "old" app in "refuse new sessions" mode and start new instances with the
new code. _______________________________________________
