Abstract
A lock control apparatus includes one or more memories, and one or more processors configured to perform setting of, as a target node, each of one or more child nodes other than eldest child nodes among child nodes relating to parent nodes in each of layers of data structure formed by a tree structure, when a first process for first data associated with a first node in the data structure proceeds in a direction from a parent node to a child node, perform determination of whether the first node is the target node, and perform lock of the first node when the first node is the target node.
Claims17
A lock control apparatus comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories and the one or more processors configured to
- perform setting of, as a target node, each of one or more child nodes other than eldest child nodes among child nodes relating to parent nodes in each of layers of data structure formed by a tree structure,
- when a first process for first data associated with a first node in the data structure proceeds in a direction from a parent node to a child node, perform determination of whether the first node is the target node, and
- perform lock of the first node when the first node is the target node.
A computer-implemented lock control method comprising:
- setting, as a target node, each of one or more child nodes other than eldest child nodes among child nodes relating to parent nodes in each of layers of data structure formed by a tree structure;
- when a first process for first data associated with a first node in the data structure proceeds in a direction from a parent node to a child node, determining whether the first node is the target node;
- and
- locking the first node when the first node is the target node.
A non-transitory computer-readable medium storing instructions executable one or more computers, the instructions comprising:
- one or more instructions for setting, as a target node, each of one or more child nodes other than eldest child nodes among child nodes relating to parent nodes in each of layers of data structure formed by a tree structure;
- one or more instructions for, when a first process for first data associated with a first node in the data structure proceeds in a direction from a parent node to a child node, determining whether the first node is the target node;
- and
- one or more instructions for locking the first node when the first node is the target node.
