15.2.1 Systems that operate the executing node and the standby node in the 1-to-1 ratio (1-to-1 node switching system)
The 1-to-1 node switching system is a system in which the executing node and the standby node are in 1-to-1 ratio. Application Server supports the operations in the 1-to-1 node switching system of Management Server. However, in the execution environment of the batch application, the Management Server is not deployed, and therefore, the operations cannot be executed in the 1-to-1 node switching system of the Management Server.
In the 1-to-1 node switching system, if some failure occurs in the executing node, the cluster software detects the failure, automatically switches to the standby node, and continues the operations. Also, even when a failure does not occur, if the running system has preventive maintenance or other requirements, you can switch to the standby node in a planned manner using the operations of the operator.
For details on the 1-to-1 node switching system, see 17. 1-to-1 Node Switching System (Linked with Cluster Software).
