I have a few basic questions, I'm coming from SQL Server, so some of the terms I've been introduced to are unfamiliar,

Someone else has installed ORACLE 8i. They have only run the setup program and are unfamiliar with ORACLE!

1. How do I tell it a repository has been setup on my machine? Is a repository setup during installation? In ORACLE ADMINSTATOR ASSISTANT FOR WIN NT, there is an object under the databases tab and I've successfully connected to it. Is that the repository?

2. Does a management server get created by setup when ORACLE is first installed, or does it need to be created manually using CONFIGURATION ASSISTANT?

3. Does a management server need to be created prior to being able to use (logging in into) OEM?

4. Can I set the Management Server to start automatically when the OS start?

Please recommend books that explain these concepts in great detail (not just reference). I did not have much success with the online documentation.

Any help is greatly appreciated.
