Can we get by with only one box for the 11i Financials implementation and get a test box after the implementation is done? What is the disk layout for Oracle Financial 11i?
For instance, I remember discussing patching and configuration management issues with a consultant after a disaster. They were two weeks before cutover (to the new system) and someone decided to implement a patch without doing a full backup first. The project manager felt they were "too busy" to do the backup. Sometimes patches have unpredictable results -- and in this case, it did. It was an AR patch which failed, in a really freaky way, wiped out the accounting structure and set the project back weeks.
Patching is not the only issue in whether you have one, two, three or more instances. If you have any custom development work, you will want to test it before adding it to what will be your production instance.
If you are starting a new implementation, at some point you will want to start training your users. You will not want to train them on the same instance that you are building for production.
Also, you will probably want a separate box for the Oracle Application Server (which performs the browser interface).
If you use Rapid_install, the install will create your structure for you.
From the applications manual:
