PRGZ-03681
Disaster recovery migrations require both target databases to be in different hosts but '{0}' (-targetnode CLI parameter value) and '{1}' (TGT_STBY_NODE RSP parameter value) are specified instead.
Cause
An attempt to migrate a database with disaster recovery enabled using zero downtime is being rejected because both target databases are in the same host.
Action
Specify both target databases in different hosts and if possible in different Availability Domain, Fault Domain or Region as indicated on Oracle Maximum Availability Architecture (MAA) best practices then retry the operation.
