ORA-16052: DB_UNIQUE_NAME attribute is required

What triggered the Error:

The DB_UNIQUE_NAME attribute is required when DG_CONFIG is enabled.

Use the DB_UNIQUE_NAME attribute to specify a valid Data Guard Name for the destination. The list of valid DB_UNIQUE_NAMEs can be seen with the V$DATAGUARD_CONFIG view.
