RE: DBA's that tune duhveloper's SQL

I tend to find that tuning is a joint effort between the DBA and the developers. Even the most senior developers that I have worked with tend not to understand that internal workings of Oracle which is sometimes what is needed.  

For example, I've found that developers understand that select...for update; will lock the rows that are selected but they do not understand that the consequence is more redo is generated. So in a effort to be unnecessarily safe they unwitting consume more database resources than would otherwise be needed.  

And of course not all databases behave in the same way so tuning can be somewhat different depending on the DB vendor - a DBA can help clarify the differences.

We have a consultant doing some work at our site and he claims that in most shops the DBA's have the responsibility of tuning duhvelopers code. I find that hard to believe. I was wondering if maybe I am out of most of you also tune all your duhvelopers code??? I can see working together with them if there are issue but have the responsibility of tuning all developer code....EGAD when would I have time to be a DBA. ; )
