But if retrying fails means, something is wrong in the setup. We need to fix that before creating apps again. However, yes, roll back helps to get the appId back, so you can create the application with same appId even after it failed. However retrying will help in case of intermittent issues. thank you. > > WDYT? > > Thanks, > Janaka > >> >> thank you. >> >> >> On Mon, Jan 6, 2014 at 10:06 AM, Ashansa Perera <asha...@wso2.com> wrote: >> >>> Hi all, >>> >>> To make the application creation process resilient we discussed to >>> implement a rollback mechanism so that if any resource/infrastructure >>> creation failed while creating the application we can rollback the app >>> creation.
