Redundancy
Oracle supports redundancy by running one Oracle Utilities Live Energy Connect (LEC) Server instance and one or more standby LEC Server instances. These instances all run on different physical or virtual machines. All redundant LEC Server instances have identical ICCP link configurations. However, only one LEC Server instance can be online at one time. When an LEC Server instance is online, in Active mode, it is the only LEC Server with active ICCP associations and connections to the application’s OPC client connections.
Each LEC Server instance has a Master Control variable that controls whether it is operating online (Active mode) or on standby (Passive mode).
