The thing is that installing the X window system means installing a hell of a lot of extra code. All that extra code means a lot of extra possible vulnerabilities. The connection between your desktop and the server also needs to be secured (read: encrypted), otherwise anybody on your network can see whatever you're doing on the server and could even take over your session without you knowing it. Anything running in X is also a lot harder to secure and isloate from the rest of the system. This means your desktop needs to be absolutely secure. Should a hacker take control of your desktop, it would become relatively easy for him to compromise the server, unless the server is properly hardened with SELinux etc. - requiring a lot of extra time of the server administrator.
I'm not gonna go into any more technicalities here, but it is considered a bad practice to install X on a server when it can deliver its services without X.
I don't know anything about databases, but I'm inclined to agree with your sysadmin. If there is a way for you to do what you want to do without requiring the X window system to be running on the server, you should do that.
Would it be possible to securely mount a network drive to your desktop and use the DBCA client on your desktop to create and manage databases on the server's disk?
