Hi everybody,

we have a data guard as it shown below:

DGMGRL> show configuration ;

Configuration - RDG

  Protection Mode: MaxAvailability
  Members:
  SW67    - Primary database
    FRSC    - Far sync instance
      SW66    - Physical standby database
        LGSTDBY - Logical standby database (receiving current redo)

Fast-Start Failover: DISABLED

Configuration Status:
SUCCESS   (status updated 49 seconds ago)

next, you can check the status after I've created a catalog and registered the primary database, and configured all DB_UNIQUE_NAME for the Primary and all standbys.
