Embodiment
Below in conjunction with accompanying drawing and preferred embodiment technical scheme of the present invention is at length set forth.Should be appreciated that following listed examples only is used for explanation and explains the present invention, and does not constitute the restriction to technical scheme of the present invention.
As shown in Figure 1, be the flow process of cluster management node updates state embodiment in the method for the available cluster condition monitoring of height of the present invention, comprising:
110: management node is received the notice that the clustered node state changes;
120: know the cluster Status Change according to the variation of each clustered node state, upgrade the cluster state of local record;
130: make up information updating message, and this message is sent to all other nodes in the cluster.
Other each node of cluster receives that the handling process after the information updating message that management node sends is as shown in Figure 2, comprising:
210: other node of cluster is resolved this message after receiving the information updating message of reflection cluster state variation;
220: know the cluster state of renewal according to the message of resolving, and the cluster state that upgrades is documented in this locality.
The present invention is directed to said method embodiment, the device embodiment that realizes high available cluster condition monitoring correspondingly also is provided, its structure is as shown in Figure 3, comprising: interconnective information interaction module and state update module, wherein:
