Managed stand by data base
To make sure high availability oracle provide a managed stand by data base future A stand by data base is a copy of the regular data base i.e. in solved on the separate system. If a catastrophic failure occur on the primary system, the stand by system is activate and take over there by minimizing effect on failure on a availability.
