Embodiment Construction
[0023] The specific implementation steps of the present invention will be further described below in conjunction with the accompanying drawings and specific examples, but the examples should not be construed as limiting the present invention.
[0024] In a database cluster system based on a shared disk, there are 4 database nodes and 1 global resource management node. Wherein, the database node refers to a server that provides database services, and is used to accept a user's database query request and return a result. It is an integral part of the database cluster system, and there can be one or more. The global resource management node refers to the node that provides the shared resource management service of the database cluster system. It is a core component of the database cluster system, which includes a global buffer manager for managing buffers. The global buffer manager can implement functions such as content indexing, version management and attribute modification o...
