The server-side autocommit setting was removed and reimplemented in client applications and languages. Server-side autocommit was causing too many problems with languages and applications that wanted to control their own autocommit behavior, so autocommit was removed from the server and added to individual client APIs as appropriate.
set autocommit to on;
set autocommit to off; removed
Autocommit is always true at the moment
hope this helps
