[jira] Created: (GERONIMO-557) smooth application upgrade/versioning
smooth application upgrade/versioning
-------------------------------------
Key: GERONIMO-557
URL: http://issues.apache.org/jira/browse/GERONIMO-557
Project: Apache Geronimo
Type: New Feature
Reporter: David Jencks
There have been several requests for the ability to change fairly fundamental bits of application configuration at runtime, such as which resource a resource-ref points to. Currently the only way to do this is to redeploy the reconfigured application, and changing this would break a lot of our implementation and some of our philosophy.
Perhaps a better way to approach this kind of problem is to version applications, and have a process for seamlessly switching between versions of an application.
So, to change the target of a resource-ref, you'd configure a new "copy" of your app with the new target, deploy it, and undeploy the old version.

[jira] Commented: (GERONIMO-557) smooth application upgrade/versioning

Sandip Ghayal commented on GERONIMO-557:
----------------------------------------
Also we should allow facility where one can change the plan without need to redeploy the Application.
EJB1 points to Resource1 in plan ABC, version 1
EJB1 point to Resource2 in Plan ABC, Version 2.
Actually deploying version 2 of application could take lot of time and might not be required if the changes are just configuration changes, like e.g. above. So having a facility to hot swap the plans could be really useful.
