Is it possible to disable use of fast forward-only cursor on server side?
No, it is not possible to disable fast forward cursors on the server side, as far as I know.

If your application requests a fast forward cursor, that is what it will get, at least in 'modern' versions of SQL Server (2005+). From Using Implicit Cursor Conversions:


  Fast forward cursors are never converted.


I have long since forgotten what might or might not have worked on SQL Server 2000 and earlier in this scenario. You might find one of the implicit conversion cases in the document you reference can be made to work for you temporarily.

Back to the modern world. The fast forward cursor may compile to a static-like or dynamic-like plan, but the restriction to only generate a non-parallel plan will remain in either case.

There is generally no single class of cursor or set of options that will perform acceptably well in all situations. For best performance, the type of cursor and the options set need to be evaluated for each case.
