Like most things oracle... "It depends"

In large shops > 500 databases I don't think there is a way around the silo (app/system) approach - "today". There are probably just too many dbs involved to keep things standardized and maintainable.

My environment is >1500 databases and we have about 10 dbas to handle system work, I think there are well over 50 app dbas, for the most part the skills don't overlap at all. In this environment you are definitely going to loose major skills where as to severely limit your career. Unless you spend your free time playing with the other side of the technology.

The real problem I have with it is, management is constantly trying to divide an conquer and that's easiest to do in a silo approach and even easier on the system side of things. So, I find my work has gotten highly process orientated and technologically "dumbed down". (so "anyone" could support it). To get anything done , you might as well have both hands tied behind your back and type with a pencil in your mouth.

When I started there about 5 years ago, there were small teams of about 5-8 dbas pretty much grouped by application. A very good well rounded  atmosphere.

The first swipe was get everyone together to support each others apps, then downsize, then split app/system - then outsource. Install more processes so every breath can be counted and continue to "manage" the "team" to be "more efficient", repeat above.
