Distributed lock manager
The DLM employs a distributed, centralized tree design. It does not replicate lock information on each cluster member. Rather, the cluster member that manages a lock tree maintains all information about that tree. The member that holds a given lock is aware of only its contribution of that lock to the resource. Any member system can serve as the master for any lock tree, which distributes the overall lock management load.
