There is one pitfall: If you changed the database shema, EOModel and use
ERXMigration (what have I done without?)

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. _______________________________________________
