After "ALTER DATABASE OPEN RESETLOGS" queries on V$ARCHIVE_GAP doesn't return
SQL> select * from v$archive_gap;
returns no rows selected
even when GAPs are actually there.
This can happen when the standby database has different incarnations.
Database creates a new incarnation whenever a database is opened with the RESETLOGS option (eg. flashback, failover).
