Abstract

An embodiment of the present invention discloses a lock operation method of a database system. The method comprises: a first processing node acquiring a lock operand of a target lock; the first processing node performing a locking operation on a target data object by using the target lock; and when the lock operand meets a condition of an successful locking operation the first processing node determining that the locking operation is successful and updating a value used for indicating a state of the target lock on the first processing node of a data bit in the lock operand to a value used for indicating that the target lock is in a locking state on the first processing node. Correspondingly an embodiment of the present invention also discloses a node device. By using the embodiments of the present invention performance of a database system can be improved.
