ORA-16814: incorrect redo transport setting for AlternateLocation for standby database

What triggered the Error:

The Data Guard broker detected an incorrect redo transport setting for a standby database AlternateLocation property. The incorrect setting could be one of the following: *- The AlternateLocation property was empty, but the redo transport to the standby database had an ALTERNATE setting. *- The AlternateLocation property was not empty and the redo transport to the standby database had no ALTERNATE setting. *- The AlternateLocation property did not match the ALTERNATE setting in the redo transport. The mismatch may include service string, directory specification of the alternate location, or the DB_UNIQUE_NAME attribute. *- The LOG_ARCHIVE_DEST_STATE_n parameter corresponding to the alternate location was not set to ALTERNATE. *- The flash recovery area was being used by the standby database for archived logs, but the redo transport to the standby database still had an ALTERNATE setting for the AlternateLocation property. Data Guard broker logs provide more details on which of the above cases caused the error.

What should we do to fix it:

Reenable the primary database to clear the error.
