In [SCH81] some aspects of optimistic concurrency control (CC) in distributed database systems have been discussed, some important problems have, however, not been dealt with in sufficient detail in the paper but only in the oral presentation. Thus, the reader of the conference proceedings might get the impression that optimistic CC, as introduced in [KUR79], is very easily adapted to distributed systems. Unfortunately, when looking into the problem more thoroughly, the contrary turns out to be true. This note is meant to highlight the main problems of optimistic CC in distributed database systems. We cannot discuss possible solutions in detail - this will be done elsewhere.
