Re-deploying application developed by PDK

Question

Hi,
Our portal users are using the applicatoin developed by PDK.
However, we are planning to re-deploy the application developed by PDK.
Here is my questions.
1. Is it possible for portal users to use the current PDK developed applicatoin during re-deploying process?
For example, if the re-deployment takes 10 mins, can the portal user not use the application in that period?
anybody has same experience before?

Answer 1

Hello John,
it depends on the structure and content of your PDK project. If you are using RFServiceWrapper to register your class in CrtClassLoaderRegistry, then you also need to restart J2EE, in order to update previosly deployed class.  In this case, your changes will take effect only after restart (users must stop using the app).
In general, re-deployment consists of two steps:
1 undeploy previous version.
2 deploy the new one.
It means that there is always an time period (relatively small) when your app is not available. If any of users try to access (send a request to) your app. , then he gets an error message (Could not found....).
But there are several options, how to forbid using the app durign the deploy (hide the access point - role; deploy app. with other name, create another iView and then just redirect your users, and so on...). Of course, only if it's not conflicting with your business processes.
