Embodiment 1
[0057] Embodiment 1: The member node that applies for a shared resource lock for the first time in the system is used as the lock management node of the shared resource.
[0058] Assume that there are 5 member nodes in the computer cluster system, namely: node 1, node 2, node 3, node 4 and node 5;
[0059] There are 10 shared resources in the system, namely: shared resource A, shared resource B, shared resource C, shared resource D, shared resource E, shared resource F, shared resource G, shared resource H, shared resource I and shared resource J ;
[0060] Each node (node 1-5) in the system stores a global resource directory information table, and the global resource directory information table includes at least two fields: shared resource name and corresponding lock management node. When the system is initialized, there is no record in the global resource directory information table in each node; when the system starts and runs, the application process in one or more node...
Embodiment 2
[0067] Embodiment 2: The corresponding lock management node of the shared resource is established through the hash algorithm.
