It actually means that TNS service at the primary database host is not properly configured to connect with the AUXTILIARY database specified in the connect string in above command block (C:\Users\administrator>rman target sys/pass11g@pri auxiliary sys/pass11g@aux). You should make sure that “aux” TNS service is properly configured at the primary site and you can connect with the auxiliary instance using this TNS service.
