Yes, it does, trust me and others who have stated the same in this thread. Oracle is run on Windows, yes, but the majority of Oracle installations are on UNIX/Linux and, as such, you need, yes NEED, a good understanding of UNIX system administration. Such knowledge even helps those who find themselves in Windows shops. Again, trust me on this as I've been in both worlds working production Oracle databases and, even with Windows, I wouldn't have had much chance without the UNIX administration knowledge I gained when I started some 17 years ago.

I suppose you'll next be asking 'why'? Oracle runs on top of an operating system, most often UNIX/Linux; knowledge of the opreating system process management, memory management, user management and kernel configuration is a must. Also, such knowledge is not wasted with Windows, as it make transition much easier between the two operating systems.

If a person cannot manage a UNIX installation, including kernel patches, user administration, resource allocation, etc. one cannot truly hope to be a qualified Oracle DBA. You simply do not paint half a portrait and sell it as a finished product.

Knowledge of Oracle is not enough. One must be capable of assuming the role of backup system administrator as well. There is no compromise on this. Research how often Oracle is installed on UNIX compared to Windows; when you do, you'll find it is the most often selected operating system for Oracle. Then ask other DBAs in those shops what qualifications they need. You'll find, as Daniel and Sybrand have indicated, that UNIX System adminsitration is at the top of their lists. And, the best Oracle DBA's I've had the pleasure to meet or with whom I've worked have been excellend UNIX sys admins. You are deceiving yourself if you think otherwise.
