Hi,
I think you must add Standby Redo logfiles .
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/oracle/ordata/<primary>/log1c.rdo') SIZE 500M;
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/oracle/ordata/<primary>/log2c.rdo') SIZE 500M;
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/oracle/ordata/<primary>/log3c.rdo') SIZE 500M;After that you can edit database primary log transport to SYNC and in broker managed data guard you must chage logxptmode to sync on standby ,too
With
DGMGRL> edit database  <primary> set property LogXptMode="SYNC";
DGMGRL> edit database  <standdby> set property LogXptMode="SYNC";
DGMGRL> edit configuration set protection mode AS MAXPROTECTION;
Max protection is require restart  primary database;
DGMGRL> shutdown immediate; -- if connected to  primary
DGMGRL> startup;
DGMGRL> edit configuration set protyection mode as MAXAVAILIBILITY;Regards
