17.4 Settings of the 1-to-1 node switching system of Application Server (In Windows)
The 1-to-1 node switching system is a system in which you set the executing node and the standby node in 1-to-1 ratio. In Application Server, you can build and operate a system in which you deploy one Application Server of the executing node for one Application Server of the standby node, and a system in which you deploy one Management Server of the executing node for one Management Server of the standby node. Use the management portal to build a system in which you deploy Application Servers in 1-to-1 ratio. For details on the management portal, see the uCosminexus Application Server Management Portal User Guide. This section describes the settings for a node switching system in which you deploy the Application Server of the executing node and Application Server of the standby node in a 1-to-1 ratio.
In node switching systems, where you deploy the executing node and the standby node of Application Server in 1-to-1 ratio, if a machine failure or failures such as termination of the Administration Agent occur in the Application Server of the executing node, the cluster software detects the failure, and continues the operations by automatically switching to the standby node. Also, even if a failure does not occur and the operating system requires preventive maintenance, the operator can switch to the standby node in a planned manner.
For details on the 1-to-1 node switching system of Application Server, see 17.2 Overview of 1-to-1 node switching system. For system configuration, see 3.11.1 Configuration in which executing node and standby node of Application Server are in 1-to-1 ratio (when transaction service is not used) and 3.11.2 Configuration in which executing node and standby node of Application Server are in 1-to-1 ratio (when using transaction service) in the uCosminexus Application Server System Design Guide.
