Abstract
Method and apparatus for locking by sharing lock states. Each resource is associated with a lock state that represents its lock. Lock states are made of one set of transactions per locking mode. Resources may share the same lock state if the state of their respective locks is equal. Locking operations change the association between a resource and a lock state to reflect changes to the resource's lock.
