It depends, if it is small shot you have to put multiple hats whihc means you have to support OS, Dev and DB etc...
In big shops you will have individuals for different things like for networking NETWORK guys and applications and OS then SYSTEM guys for database DB guy....
If no one there to support then there is no harm to learn applying the patches and/or installing service packs...
