The 1-to-1 node switching system is a system in which the executing node and the standby node are in the 1-to-1 ratio. With the 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 the Management Servers in the 1-to-1 ratio. This section describes the settings for a node switching system in which the Management Server of the executing node and the Management Server of the standby node are deployed in the 1-to-1 ratio.

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

Note that you can only use the operations of the 1-to-1 node switching system of the Management Server in AIX, HP-UX, or in Linux.

For details on the functionality, 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. Also, for details on the HA monitor, see the manual Reliable System Monitoring Functionality HA Monitor.
