ORA-16775: target standby database in broker operation has potential data loss

Cause: The target standby database specified for the broker operation did not have all the redo data from the primary database.

Action: Confirm that the redo transport service on the primary database is functioning correctly by checking its status using either Enterprise Manager or the DGMGRL CLI SHOW DATABASE command. Reissue the broker command once all redo data is available on the target standby database.
