5.2. Lock St at es
A lock state indicates the current status of a lock request. A lock is always in one of three states:
Granted — The lock request succeeded and attained the requested mode.
Converting — A client attempted to change the lock mode and the new mode is incompatible with
an existing lock.
Blocked — The request for a new lock could not be granted because conflicting locks exist.
A lock's state is determined by its requested mode and the modes of the other locks on the same
resource.
