Abdul,
You can choose whether to archive redo logs to a single destination or multiplex them. If you want to archive only to a single destination, you specify that destination in the LOG_ARCHIVE_DEST initialization parameter. If you want to multiplex the archived logs, you can choose whether to archive to up to ten locations (using the LOG_ARCHIVE_DEST_n parameters) or to archive only to a primary and secondary destination (using LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST). The following table summarizes the multiplexing alternatives, which are further described in the sections that follow.
LOG_ARCHIVE_DEST_n : LOG_ARCHIVE_DEST_1 = 'LOCATION=/disk1/arc'
LOG_ARCHIVE_DEST_2 = 'SERVICE=standby1'

Vamsi.
