Can someone tell me in some kind of priority why specifically you need root Access to UNIX. I am not a UNIX Administrator, but I am familiar with NT, WIN2K administrator roles. So I'm not a total idiot, just a partial one when it comes to UNIX. We have a Compaq Alpha running tru64 UNIX and our hosts say they need exclusive root access, which means our people don't have root access, they also want to take away our Oracle DBA priveleges. I hear a number of reasons from various people that we can't do this but nothing concrete.
What are the differences between root, sys, and system?
If the question requires more points please let me know that as well.
