Abstract: A database system lock operation method is provided that includes: acquiring, by a first processing node, a lock operand of a target lock; using, by the first processing node, the target lock to perform a lock acquiring operation on a target data object; when the lock operand meets a condition for a successful lock acquiring operation, determining, by the first processing node, that the lock acquiring operation is successful, and updating a value of a data bit that is in the lock operand and used to indicate a state of the target lock on the first processing node to a value that is used to indicate that the state of the target lock on the first processing node is lock held. Accordingly, the embodiments of the present invention further disclose a node device. The embodiments of the present invention can improve performance of a database system.

Abstract translation: 提供了一种数据库系统锁操作方法，包括：由第一处理节点获取目标锁的锁操作数; 由所述第一处理节点使用所述目标锁来对目标数据对象执行锁获取操作; 当锁定操作数满足成功锁定获取操作的条件时，由第一处理节点确定锁获取操作成功，并且更新在锁操作数中的数据位的值并用于指示状态 的第一处理节点上的目标锁的状态被锁定到用于指示第一处理节点上的目标锁的状态被锁定的值。 因此，本发明的实施例进一步公开了节点设备。 本发明的实施例可以提高数据库系统的性能。
