Question re Fusion Middleware Repository

Question

Greetings,
Hopefully this is the proper place to post this question and hopefully I can articulate it properly. I am new to Fusion Middleware and I am at the point of using the repository creation utility to manage the repository. This is a new installation.
I come to the rcu utility page where I am asked to create a new prefix. That I understand. My question is, how do I see what prefixes are already in use for a particular component/schema owner? Is there a view in the repository which enables me to see this information?
Also, is it possible to remove an existing prefix and if so how?
Part of my confusion is that I don't really understand how the prefix is utilized. I don't see an explanation anywhere in the documentation. Any help is greatly appreciated.
Thank you.

The prefix will be part of a schema name in a database. If you go into a sqlplus commandline and issue:
select username from all_users;
You will see all of the existing schemas/users, such as <PREFIX>OIM, <PREFIX>MDS, etc. You can connect as a user:
conn <PREFIX>_OIM/<pwd>@SID
You can see what components are already installed against a prefix when you select that prefix going through RCU again. Assuming install mode, you will see the "already installed" components grey'd out.
There is also a remove/drop mode in RCU. Once you remove all of the components utilizing a prefix, you have essentially removed the prefix.
