String 

Dynamic. Scope = ALTER SYSTEM. 

None  

Either a null string or any valid path or device name, except raw partitions 

Note: If you are using Oracle Enterprise Edition, this parameter is deprecated in favor of the LOG_ARCHIVE_DEST_n parameters. If Oracle Enterprise Edition is not installed or it is installed but you have not specified any LOG_ARCHIVE_DEST_n parameters, this parameter is valid. 

LOG_ARCHIVE_DUPLEX_DEST is similar to the initialization parameter LOG_ARCHIVE_DEST. This parameter specifies a second archive destination: the duplex archive destination. This duplex archive destination can be either a must-succeed or a best-effort archive destination, depending on how many archive destinations must succeed (as specified in the LOG_ARCHIVE_MIN_SUCCEED_DEST parameter).  

The default setting of a null string ("") or (' ') indicates that a duplex archive destination does not exist.
