The N-to-1 recovery system has one configuration in which you prepare one standby node (recovery server) for N number of executing nodes. When using a global transaction in a configuration with redundant J2EE servers, use the N-to-1 recovery system to terminate the transaction when an error occurs in a particular J2EE server. Use the management portal to build this system. For details on the management portal, see the uCosminexus Application Server Management Portal User Guide. This section describes the settings of the N-to-1 recovery system.

Execute applications in N number of executing node Application Servers. If a failure occurs on Application Server in which applications are running, the cluster software detects this failure, and the recovery server terminates the transaction running on Application Server in which the failure occurred. Following this, application continues processing in the remaining executing node Application Servers that are operating.

For details on the N-to-1 recover system, see 19.2 Overview of the N-to-1 recovery system. For the system configuration, see 3.11.5 Configuration for using a recovery server (N-to-1 recovery system) in the uCosminexus Application Server System Design Guide.
