          Hi

          Maximum availability=this mode is mixture of maximum protection and maximum performance mode.Primary database dont tell operation completed to end user until write redo data both primary online log and standby online log file.if it can not write redo data to standby redo log during the time specified by net_timeout parameter it operates as in maximum performance

           

          Maximum protection=this mode ensures that no data loss while  primary database is fail.Primary database dont tell operation completed to end user until write redo data both primary online log and standby online log file.primary database has failed if primary database can not write redo information to at least one standby database logfile.

            Hello;

             

            All 3 modes are described here:

             

            Data Guard Protection Modes

             

            Not sure I would call  any of them "highest mode". What does the business need?

             

            Best Regards
