The 1-to-1 node switching system is a system in which the executing node and the standby node have the 1-to-1 ratio. In Application Server, you can build and operate a system in which one Management Server of the executing node is deployed for one Management Server of the standby node. You use the Smart Composer functionality to build a node switching system by deploying Management Servers having the 1-to-1 ratio. This section describes the settings for a node switching system in which Management Server of the executing node and Management Server of the standby node are deployed with the 1-to-1 ratio.

In a node switching system where Management Servers are deployed with the 1-to-1 ratio, if a machine failure occurs or if Management Server processes terminate in Management Server of the executing node, the cluster software detects the failure, automatically switches to a standby node, and continues operations. Also, even if failure does not occur and the running system requires preventive maintenance, the operator can switch to a standby node in a planned manner.

For details on the 1-to-1 node switching system of the Management Server, see 17.2 Overview of 1-to-1 node switching system. For system configuration, see 3.11.3 Configuration in which the executing and standby nodes of Management Server have 1-to-1 correspondence in the uCosminexus Application Server System Design Guide.
