Subject RE: Guidelines for deploying Geronimo in a production system
Date Thu, 24 Apr 2008 19:26:15 GMT

Your input has been very useful.
I would like to prepare a document or set of documents to my team here. I
have never done this 
kind of thing before (deploying an Application Server in production). How
can I put together a production plan or something.
I will utilize the information provided by you. By architecture and
requirements documents, what exactly should I address?
