Problems solved by technology

[0003] The existing high-availability cluster resource management is mainly managed through a one-way linked list. One of the one-way linked lists manages the cluster group, and the other one manages the resources in the group. There are two main problems in this management method: one is the group and Resources are managed separately, resulting in unclear associations between groups and resources, and resource names in different groups cannot be the same
The second is that the resources of all groups are managed through a linked list. When operating on a certain group or resource, it is necessary to traverse all resources, which affects the resource switching time

Embodiment

[0016] A high-availability cluster resource management method described in this embodiment uses a two-level AVL tree to manage groups and group resources in the cluster in a high-availability cluster; establishes an association relationship between groups and group resources through a two-level AVL tree , specify the relationship between groups and group resources. The high-availability cluster resource management method manages the cluster resources through a tree structure, improves the search speed of the cluster resources, and further improves the resource switching time.

[0017] This high-availability cluster resource management method is mainly used in high-availability cluster management software to optimize resource information management methods in high-availability clusters. Groups and group resources in the cluster are organized and managed through two-level AVL trees; the first-level AVL tree management The cluster group uses the cluster group name as the key valu...

Abstract

The invention discloses a method for managing high-availability cluster resources and relates to the field of high-availability cluster software. In high-availability cluster resource management, a two-stage AVL tree is used to manage groups and group resources in clusters, an original linked list management mode is replaced; the incidence relations of the groups and the group resources are established through the two-stage AVL tree; and the incidence relations of the groups and the group resources are clear. The resources are managed through the AVL tree, the resource switching time is reduced, the service interruption time is shortened, and the competitiveness of high-availability cluster products is improved.

Description

technical field [0001] The invention relates to the field of high-availability cluster software, in particular to a high-availability cluster resource management method. Background technique [0002] With the rapid increase of Internet information and the development of e-commerce, people have higher and higher requirements for business reliability and continuity. Whether an Internet company can provide high-reliability services has a great impact on the company's recognition. The emergence of high-availability cluster technology caters to the needs of various high-reliability services. [0003] The existing high-availability cluster resource management is mainly managed through a one-way linked list. One of the one-way linked lists manages the cluster group, and the other one manages the resources in the group. There are two main problems in this management method: one is the group and Separate management of resources leads to unclear association between groups and resourc...
