Definicja optimistic lock
Possible value of the lock mode of a lock object.
As with read locks, several transactions can request an optimistic lock on an object. If the data then really has to be changed, the optimistic lock is converted into a write lock (mode E) and other optimistic locks on the object are invalidated.
Write locks are indicated with 0 in the lock administration.
