yes your dataguard work in both modes logging and nologging but in nologging some of the tables .anbd transaction would be miss.

Nologging means no redo if no redo no redo would transfer to standby .

As you know dataguard get data from archiveslogs or standbylogfiles so its really really important for your database should be in logging mode.

And this is the ist command in dataguard configuyration steps

• SQL> Alter database Force Logging;

Quote:
NOLOGGING or Unrecoverable Operations
When you perform a DML or DDL operation using the NOLOGGING or
UNRECOVERABLE clause, the standby database is invalidated and might require
substantial DBA administrative activities to repair. You can specify the SQL ALTER
DATABASE or SQL ALTER TABLESPACE statement with the FORCELOGGING clause to
override the NOLOGGING setting. However, this statement will not repair an already
invalidated database.
